PURPOSE Three male patients with a history of spray-paint inhalation are presented. METHODS Spin-echo MR was used to evaluate the central nervous system changes secondary to toluene inhalation delivered via spray-paint fumes. RESULTS The remarkable findings included the loss of cerebral and cerebellar gray-white matter discrimination, scattered multifocal deep white matter lesions, and gros...

A 46-year-old man who had worked as a bumper spray painter in an automobile body shop for 15 years developed lung cancer. The patient was a nonsmoker with no family history of lung cancer. To determine whether the cancer was related to his work environment, we assessed the level of exposure to carcinogens during spray painting, sanding, and heat treatment. The results showed that spray painting...

The scope of this paper and presentation is to address the properties and benefits of the alkaline cyanide-free zinc deposit as a base coating for paint and powder coating applications. The deposition structure and process characteristics for alkaline cyanide-free zinc plating will be evaluated and compared to acid chloride zinc plating, zinc phosphating and iron phosphating. Salt spray testing...

This study assessed the relationships between ethylbenzene exposure and levels of 8-hydroxydeoxyguanosine (8-OHdG) among spray painters. Sixty-four male workers employed at a large shipyard were recruited for this investigation. Fifteen spray painters exposed to paint, together with two non-exposed groups, namely 19 sandblasting workers and 30 office staffs were selected as the subjects. Person...

We develop a procedure for automated trajectory generation for robotic spray painting applications. Painting requires that the spray gun deposit paint at each point on the target surface such that the variation of the resultant paint deposition is within acceptable limits; we term this the uniform coverage problem. To understand the key issues in the uniform coverage problem, we consider surfac...

Anticorrosion protection on the basis of water-thinnable paint systems belongs among one of ecological ways of protection of metal parts. The aim of the experiment was to test corrosion resistance of water-thinnable systems Eternal antikor speciál V9503 and Colorlak aquarex V2115 in the salt spray environment according to the norm ČSN ISO 9227. Ductility of used paint systems in complience with...

Automated 3D path and spray control planning of industrial painting robots for unknown target surfaces is desired to meet demands on the production system. In this thesis, an image acquisition and laser range scanning based method has been developed. The system utilizes the XY projection of the boundaries of the target surface to generate the gun trajectory’s X and Y coordinates as well as the ...
