A thin brittle wafer 30, such as a silicon disc 0.25 mm (.01") thick and 75 mm (3") in diameter, is firmly held so as to allow the wafer to be brought into abrading contact with a moving lap wheel 14, by means of a pad 40 of resilient but firm cellular material bonded on a pedestal 36, both the pad and the pedestal surface it is upon being lapped flat. A film 62 of a liquid which is preferably wat...

A process for the production of an expandable silicone resin includes reacting a substantial amount of the silanol (SiOH) groups present in the resin to form siloxane bonds and water, and heating the resin to a temperature above the resin's melting point, at which chemical reaction (condensation) of the silanol groups occur. The reaction increases the molecular weight of the resin and decreases th...

Production of acrylic resin plates in which upper and lower endless belts (1,1'), e.g. 1500 mm wide, run parallel to one another at 0.5-4.0 m/min, and thin acrylic resin film, transparent or with a printed pattern, is supplied onto the top stretch of the upper belt after a coater (17), e.g. a methacrylate polymer brush unit, has coated this belt's surface. Monomer or partially polymerized acrylic ...

A method for preparing flame-resisting modacrylic fibers containing pentavalent antimony oxide is described wherein the antimony oxide is suspended in a mixture of water and an organic solvent selected from dimethylformamide and dimethylacetamide and the suspension is then mixed with the viscose solution of the modacrylic polymeric material to be spun. The process yield high luster, flame-resistin...
