Latest Patents
One of his latest patents is a method for coating a solid closed surface. This method involves using a peelable adhesive masking film, which is lifted off the surface at one end. A low viscosity coating composition is then poured into the wedge formed by the lifted film. As the masking film is pulled off further, the wedge moves along the surface, allowing for efficient coating. The coating composition in the wedge is replenished at the rate at which it is consumed. Another significant patent is a transfer printing process for solid objects employing high-pressure gas. This process describes how to transfer print onto solid substrates made of plastics or those with a surface layer of varnish or plastic. A sheet dye carrier, heated to a suitable temperature for dye transfer, is pressed against the surface using superatmospheric gas pressure. The surface to be printed is maintained at a temperature below the thermoplastic range during the transfer process.
