  Infomercial from Mitsuba Systems  

The MAGIC EYE Part Sensing System is an Automatic Sensing system for triggering Automatic Gun on and off - depending on workpiece presence & workpiece size.

It consists of an advanced PLC controller along with Vertical and Horizontal sensor on a touch screen. These sensors are placed at the entrance of the booth just outside. They sense the changes in height of the part and trigger on the appropriate number of guns. Thus if the part entering the booth is of a small height, less number of guns shall be triggered on and if the length of the part is taller the PLC system shall trigger on more number of guns. These sensors also check for line gaps (i.e. missing parts on conveyor / empty jigs) and appropriately trigger on / off the respective number of guns.

Reciprocators / Wagglers / Oscillators can be coupled to horizontal movement systems. The MAGIC EYE sensors can move them in / out horizontally while keeping track of the changing width of the part. This automatic intelligent gun triggering system shall result in better productivity, lesser overspray of powder; high quality finishes and is a great tool to save money on the floor shop.

Upgrade procurement rules: paints body

The Indian Paints Association (IPA) has urged the ministry of defence, government of India (GoI) to set up a task force for reviewing and upgrading paint procurement specification.

“The defence minister, GoI Pranab Mukherjee has been requested to set up a task force to review inspection and purchase specification of paints. The minister has consented to consider the matter,” said Promod K Khanna, president, IPA at their 42nd Annual General Meeting.

The defence often purchase paints according to their own specification which in most cases follows the old technology, he explained.

It was further informed that ministry might from now will accept self certification, subject to certain specification.

The paint consumption by defence is to the tune of 25 lakh litre worth Rs 80 crore purchased from a scattered market.

“Defence will get a better value for money if they start procuring the paint that are produced using best technology. It would significantly reduce revenue loss due to corrosion,” said Subir Bose, managing director, Berger Paints India Ltd.

Changing specification will not be an easy task but the association will sincerely follow up the matter with the ministry, assured Bose. <more>

Big B's Viruddh ropes in brands

Amitabh Bachchan is not the brand ambassador for Aviva Life Insurance, yet he's heard repeating 'Jiyo har pal, karo kal par control' -- the tagline of Aviva in the recent promos of the film Viruddh.

Obviously, Aviva's director marketing Vivek Khanna is kicked: "The concept of the film is in sync with our brand. Getting Amitabh Bachchan to say 'Kal Par Control' and 'Kya aap zindagi ke chote bade surprises ke liye taiyar hain' in two 30-second promos is an innovative marketing methodology evolved by our in-house team to create brand recall," he says.

For Nerolac Paints, Advista saw an opportunity in the film's script. The brand's commercial plays in the background as Amitabh Bachchan paints the house to welcome his son back from the US. <more>

Space Shuttle Coatings

NASA Celebrates Launch With Caution

KENNEDY SPACE CENTER, Fla. -- With the thunderous roar of 7.5 million pounds of thrust, equivalent to the power of a small nuclear device, the United States relaunched its era of spaceflight Tuesday, sending seven astronauts into orbit aboard the Space Shuttle Discovery. The crew of Discovery have begun their first day in orbit with a painstaking, delicate search of the exterior of the shuttle to investigate whether the spacecraft was damaged during blast-off. 

A 4cm (1.5in) piece of thermal tile appeared to break off from the Discovery’s belly during lift-off, as well as a larger piece of foam, according to Nasa flight operations manager John Shannon. Neither object struck the space craft as they fell.

NASA Says Damage to Shuttle Discovery Surface Insignificant

The U.S. space agency NASA says it has discovered no serious defects in the shuttle Discovery's surface as the result of debris impacts during Tuesday's launch. Mission managers have also extended Discovery's visit to the International Space Station for extra supply transfers. They made the decision because they had earlier suspended future shuttle missions until NASA learns how to prevent further debris strikes like the kind that doomed the shuttle Columbia mission in 2003.

07.30.05 - STS-114 MCC Status Report #09
Space Shuttle Discovery’s heat protective tiles and thermal blankets have been pronounced fit for entry after engineers reviewed the imagery and other data to judge their health.

Repair Kit (Earlier news)

During his first spacewalk, Noguchi will test new repair measures inside the shuttle's storage room that opens up to outer space.

He will also fix any thermal protection tiles that are damaged with silicon repair material. He may even have to apply a new coating of bonding material on any deep cracks and gashes in the reinforced carbon-carbon composite layer.

A repair kit using Starfire Systems Inc. pre-ceramic polymers will be tested on the Space Shuttle Discovery, which was launched Tuesday.

The kit will be one of five methods that are being developed for testing on this and future space shuttle flights. All five kits will include Starfire materials.  The kit being tested on the flight being launched Wednesday is designed to repair damage to the shuttle's heat shielding in orbit. A puncture in the wing heat shielding was responsible for bringing down the shuttle two years ago. Starfire, of Malta, N.Y., produced the polymers that are in a sealing paste developed by Alliant Technologies Inc. of Minnesota. The paste is dispensed in a caulk-gun type device. It can be used to seal small cracks and damaged coating in the shuttle's heat resistant surfaces to protect astronauts from re-entry temperatures that can be more than 3,000 degrees Fahrenheit.

The kit will be tested by astronauts on a simulated shuttle panel in the spacecraft's cargo bay during a space walk.

Discovery Launched From Refurbished Launch Pad

 KENNEDY SPACE CENTER, Fla. - While eliminating the debris that sheds from the Space Shuttle's External Fuel Tank has been one of the primary requirements for the Return to Flight mission, work to eliminate hazardous debris went far beyond the Tank. When Discovery launched this week, the Shuttle stack departed from a structure that was cleaner than ever thanks to a major corrosion abatement effort that began in April of 2004 and was completed in March of this year. The pad was be virtually rust-free.

The extensive corrosion control project at Launch Pad 39 B has corrected decades of exposure to the damaging affects of one of the most corrosive
environments in the world. Additional work on Pad A is currently underway  Harry Moore, who is part of the United Space Alliance (USA) technical
operations staff of Construction Management/Corrosion Control, said the original plan was to treat the corrosion "hot spots" on the fixed service
structure and the rotating service structure of the launch pads. "But since the existing coating is at the end of its 10-year life span,
and since we had down time, we decided on a full corrosion control effort," he said.
The first step of the 11-month corrosion control project at Pad B was to strip the 247-foot steel launch tower down to bare metal, ridding the surfaces of all the old coating and getting rid of the rust. Preparation for the blasting to take off the rust and paint took place in April. Critical items such as pneumatic tubing and light fixtures had to be covered with a heavy-duty plastic. Then, the abrasive blast cleaning began. Workers from Ivey's Construction, the Merritt Island contractor handling the job, hit the metal with a spray of crushed coal slag, a byproduct of coal- fired power plants. Moore said the crushed slag is applied with a pressure of 90 pounds per square inch. "It could cut your desk in half," he said.

The blasting was finished in January this year and the coating was applied in February and March. Applying the coating was a two-step process. First, a basecoat of inorganic zinc was applied. Then a topcoat was applied to protect the zinc .

That topcoat is a mixture of mostly Portland cement plus a few other "proprietary ingredients," according to Moore. The mixture was developed by
private industry specifically for KSC to deal with the acidic residue left behind by the Solid Rocket Boosters that help propel the Shuttle into space.
In addition to protecting the pad structures from rust degradation, the corrosion control effort aims to reduce the likelihood of foreign object debris, or FOD, a key CAIB concern.
In the past the main focus of corrosion control was preserving structural integrity. Now, following recommendations of the CAIB, corrosion control is
also focused on reducing debris from pealing paint and rusted flakes of metal. Corrosion now falls under critical debris.

This change requires more inspection and stepped-up maintenance day-to- day. Under the new system, any object the size of a quarter or larger (0.01 pounds of mass or more) will be considered to have a potential impact on launch.

In addition, a three-step process has been implemented to monitor debris. The first step is a "clean as you go" system in which all pad workers monitor for debris they may have created, and eliminate it as they work. Second, there are daily "walk-down" inspections of the tower by a designated employee. Finally, once a week, managers perform walk-downs to check for debris. This new system complements an existing corrosion tracking program that involves photographing all sections of the pad structures and filing those photos in a database.

All of these efforts -- both new and old -- have put USA on track for providing one of the cleanest, safest launch platforms ever for the Return to
Flight mission.

Agreement Reached between DuPont and Rhode Island Attorney General in Lead Poisoning Case; Agreement Will Provide Rhode Island Residents Relief, Abatement and Education

MT. PLEASANT, S.C.--(BUSINESS WIRE)--June 30, 2005--Motley Rice LLC, one of the nation's largest all plaintiffs' litigation firms, today applauded the agreement that has been reached between DuPont (NYSE:DD) and the Rhode Island Attorney General Patrick Lynch to resolve the State's groundbreaking lawsuit against the former manufacturer of lead pigment. This action by DuPont, brought about by the R.I. Attorney General, represents DuPont's agreement to help solve the problem of lead poisoning in the state. Originally filed in 1999, the suit alleges that DuPont helped to create a significant public health crisis in the state by manufacturing, distributing and promoting lead-based paint products.

Motley Rice LLC represents the State of Rhode Island in its suit against DuPont, as well as in suits against six other lead pigment manufacturers concerning the lead-poisoning crisis in Rhode Island. According to the Rhode Island Department of Health, nearly 100 Rhode Island children are lead-poisoned each and every month. This litigation is an effort by the State to make the lead pigment manufacturers take responsibility for the pervasive health hazard confronted by the Rhode Island public, including its children, parents, homeowners, landlords and taxpayers.

The agreement reached today calls for DuPont to make contributions in excess of $10 million for a variety of lead abatement, enforcement, and education programs. Jack McConnell, a senior partner at Motley Rice, applauded DuPont's decision to reach this agreement. "We are extremely pleased to see DuPont stepping up to the plate and 'breaking rank' with the other lead pigment manufacturers," said McConnell. "DuPont has done the right thing."

Attorney Fidelma Fitzpatrick of Motley Rice, who has been actively involved in the litigation, echoed McConnell's sentiments. "We are encouraged to see DuPont making the first significant industry effort to clean up the toxic lead mess in Rhode Island," said Fitzpatrick. "For decades, the State and the public have been left to do what they can to deal with a problem they did not create. The settlement with DuPont is a great first step in making sure that this industry is helping to solve the public health problem that exists."

McConnell complimented Attorney General Patrick Lynch for his ground-breaking settlement. "Patrick Lynch has worked tirelessly to bring about this precedent-setting public health benefit for Rhode Island's children and its taxpayers."

The Attorney General, together with Motley Rice and co-counsel Thornton & Naumes of Boston, Mass., are actively preparing for trial in September against the remaining defendants (Sherwin Williams, Millennium, NL Industries, ARCO, American Cyanamid and ConAgra). "We will ask the remaining defendants to accept responsibility for their roles in this public health crisis," McConnell said. <more>

DuPont sued in U.S. over chemical secrets
DuPont Co., the third-biggest U.S. chemical maker, was sued in U.S. federal courts over claims that it knew for two decades that a chemical used to make Teflon non-stick coating can sicken people.
The company said in May it agreed to settle allegations by U.S. regulators that it failed to disclose health data about perfluorooctanoic acid, or PFOA, used to make Teflon. The chemical is a likely human carcinogen, an Environmental Protection Agency advisory panel said last month.

"The class of potential plaintiffs could well contain almost every American that has purchased a pot or pan coated with DuPont's non-stick coating," plaintiffs' attorney Alan Kluger, of Kluger, Peretz, Kaplan & Berlin in Miami, said in a PRNewswire statement.

DuPont, which invented Teflon in 1938, said PFOA isn't harmful to human health and the processing agent isn't found in finished products such as pots and pans. The Wilmington, Delaware-based company said it will defend against suits filed in eight states by Kluger's firm and Oppenheim Pilelsky, based in Fort Lauderdale, Florida.

"Consumers using products sold under the Teflon brand are safe," DuPont said in an e-mailed statement. "Cookware coated with DuPont Teflon non-stick coatings does not contain PFOA." DuPont shares rose 22 cents, or 0.5 percent, to US$43.90 in New York Stock Exchange composite trading. They have fallen 10 percent this year, valuing the company at US$43.8 billion.

The lawsuits, which seek class-action status, call for unspecified damages and ask that DuPont be ordered to place warning labels on Teflon-coated pots and pans and create a fund to monitor the health of users. "DuPont's own research has shown that when Teflon is heated, it can emit a variety of toxic gases," Steve Silverman, Kluger Peretz's litigation chairman, said in the firm's statement.

The EPA advisory panel said in a draft report that the agency is underestimating PFOA's health risk, including the potential to cause breast and pancreatic tumors. DuPont on May 19 said it received a subpoena in a grand jury probe related to the chemical.

The announcement followed the settlement with the EPA. DuPont, which didn't specify the amount, set aside US$15 million in the first quarter after the April 21 preliminary agreement. The EPA said last year the penalty might reach US$300 million. <more>

Government of Canada invests in aerospace nanotechnology coatings
Coatings Flash - July 04, 2005
The government announced a $3.4 million investment in the development of new nano-technology-based coatings for the aerospace industry which will advance more environmentally sound technologies. This Technology Partnerships Canada (TPC) investment is part of an $8.6 million research and development initiative being undertaken by Toronto-based Integran Technologies Inc. through the multinational Joint Strike Fighter program.
In the aerospace and defence industry, coatings offer metal surface protection against corrosion, wear, and extreme temperature environments for landing gear and jet engine components. Current coatings technologies use hard chrome plating; hazardous to health and the environment, this method is also expensive to manufacturers.
Integran will develop its unique nano-crystalline cobalt-phosphorous coatings and deposition process technologies as an environmentally friendly and a commercially viable alternative to the current hazardous hard chrome plating process. The nano-technology coatings will have applications on the Joint Strike Fighter (JSF) program and other aerospace and defence platforms. This technology also holds the potential for broad applications in automotive, biomedical, and other industrial sectors.

DSM Coating Resins Announces Price Increases for Powder Coating Resins
Coatings Flash - July 11, 2005
DSM Coating Resins' Gerben Algra, Global Business Manager Polyesters, announced price increases in North America for the Uralac range of polyester powder coating resins. Powder polyester coating resins will increase by up to USD 0.10/lb, differentiated by product grade for all orders shipped on or after August 1, 2005 or as otherwise permitted by the terms and conditions of customer contracts. DSM with five polyester powder resin plants is a leading global supplier of resin for Coatings. Powder Coatings are used in architectural, domestic appliance, automotive and general industrial applications. Algra says the need for these further price increases is due to the continuing escalation in the cost of feedstock such as NPG and PTA, high energy costs and fuel surcharges in North America. Strong global demand was responsible for feedstock s back-to-back price hikes through 2004 and continuing into early 2005. The North American situation is exceptional as feedstock prices have been increasing throughout the second quarter of 2005 and are expected to rise further in the third quarter.

  Powder Coating Manual -General Oven Design and Operation------ (Part - 43)  
A properly designed oven will have easy access and maintenance features such as platforms, ladders, access doors, lights etc. Make sure
your oven will be simple to service so that there is nothing to discourage proper maintenance. Never make an oven too small; a longer process time can be controlled by less temperature but if the oven is too short it may be a problem, particularly if production increases necessitate an increase in line speed.

The temperature in the work package should be consistent and calibrated to reflect the set temperature at the controller. If the temperature
rises and falls during the cure cycle, or if it is inconsistent from top to bottom, the coating may have inconsistent color or gloss. For example, if the top of the oven is significantly hotter than the bottom, the gloss may be higher at the bottom of the rack.

Cold and hot spots can occur along the oven cure cycle if the oven is not properly balanced. Oven balance is accomplished by adjustment
of the air volume and velocity at the discharge cones. If the oven is balanced, the temperature in the cure cycle will remain within 10 °F
(-12 °C) of the set point.

Multiple pass ovens are common in powder coating systems. If the entrance and exit are at the same end, a temperature loss can occur
when the conveyor passes near the openings. To avoid this loss, partitions should be built to separate the 180° turns from the openings as
shown below.

Acceptance criteria for a powder cure oven should include a requirement for a range of control for the temperature throughout the cure

Occasionally, a light colored powder will yellow in the oven. This is the result of excessive temperature stress or a fouled oven environment.
To be sure that the time and temperature are accurate for the powder, a temperature-recording device should be run through the oven around
once a month. The recorder will show how long it takes to get the substrate to temperature and how long it is held at temperature. It will
also show any hot or cold spots in the oven.

Fouling of the oven occurs when the exhaust level is too low. Check to make sure that the cubic feet a minute of exhaust (CFM) is accurate
for the amount of powder being introduced into the oven. Sometimes a production increase will create more powder throughput and create
oven fouling. Check the formula provided in the cost analysis section of this Manual to determine if your exhaust volume is correct.

The rules for controlling the cure of powder are:
• require that the oven maintain a temperature within 10 °F (-12 °C) of the set point throughout the cure cycle
• measure the temperature frequently for process control
• keep the oven clean; vacuum and wipe down once a week
• measure color and gloss frequently
• have the oven burner box serviced with a planned maintenance visit every six months by a qualified service company.
