Title: Method and Apparatus for Programming and Operating a Machine Tool
IPC: G05B19/42
Filed: 1979-05-23
Abstract: Initially a template pattern, e.g. for drilling printed circuit boards, is traced manually by a tracer with a computer in "Record" mode and input position and location signals are simultaneously generated and recorded to give the relative positions of the tracer and pattern. When thus programmed, the computer is put into a "Playback" mode and output position and location signals are fed to apparatus to position the tool on the work piece in dependence of the recorded pattern and tracer positions. For accurate positioning of tool and work piece, the pattern is a template with tooling indexes that could be made on the template in "Record" mode, if desired. In the "Playback" mode, a stylus is positioned coarsely by the computer in such a manner as to engage the tooling indexes which then causes self-centering action to bring the tool and tooling indexes into alignment for accurate locations of the tool relative to the work piece. <IMAGE>

Title: Method for modifying surface properties of a shaped article of a polyvinyl chloride resin
IPC: B29C35/08
Filed: 1980-10-30
Abstract: The undesirable phenomenon of surface bleeding of a plasticizer and other additive ingredients contained in a shaped article of a vinyl chloride-based resin is prevented by formulating the resin composition for shaping the article with an ultraviolet absorber and then irradiating the shaped article with ultraviolet light having an energy distribution predominantly in the wavelength region of 200 nm or shorter. Contrary to the hitherto accepted teaching that an ultraviolet light absorber in the shaped article is detrimental when modification of the surface properties of the article is intended by the irradiation with ultraviolet light, the method is effective in preventing bleeding of the plasticizer and the effectiveness of the ultraviolet irradiation according to the method is durable even when the treated article is prolongedly used in an outdoor environment or under irradiation of ultraviolet light having a wavelength of 290 nm or longer.
