Title: Improvements relating to processes for polishing or imparting a pattern to thermoplastic polymeric plastic films or layers
IPC: B29C71/00
Filed: 1958-05-21
Abstract: A polish or pattern is imparted to the surface of a thermoplastic (e.g. cellulose acetate or polyvinyl chloride) film by applying a softening agent (e.g. water, or a mixture of water and methanol or ethanol) to the surface, which is then brought immediately into engagement with a heated surface having the necessary smoothness or pattern and maintained in engagement until the surface of the film has been substantially rehardened. The polishing or patterned surface may be that of a rotating drum, an arc-shaped surface having a rocker-like motion, or a flat surface performing a stamper movement, and is preferably heated to 180 DEG F., although temperatures between 120 DEG  and 220 DEG F. do not lead to significantly different results.  The pressure of the plastic against this surface is not critical and may range from 10 to 250 lbs./linear in. width.ALSO:A polish or pattern is imparted to the surface of a thermoplastic (e.g. cellulose acetate or polyvinyl chloride) film or layer by applying a softening agent (e.g. water, or a mixture of water and methanol or ethanol) to the surface which is then brought immediately into engagement with a heated surface having the necessary smoothness or pattern and maintained in engagement until the surface of the film or layer has been substantially rehardened.

Abstract: Divided solids react with hot gases in an annular reactor 2 (Figures show half-sections), being pre-heated and cooled in annular heat-exchangers 1, 3 by gas which moves round a closed circuit under action of fans 19, 23, the closed circuit being divided into streams 111, 1111, 11111, having different temperature ranges and a proportion of gas being withdrawn from the cool stream at 25 to allow for hot gas being injected.  Hot gas is injected from toroidal combustion chamber 4, and the fuel gas or combustion air may be preheated, by the gas withdrawn at 25 or by the hottest gas stream in a heat exchanger 14, or some of the hottest gas may be added to the combustion gases.  Heat exchangers 1, 3 comprise concentric walls of louvre construction, and one wall of preheater 1 may rotate to facilitate solids flow.  Gas and solids in reactor 2 may flow counter-currently or con-currently (Fig. 1, not shown).  A blade-type extractor may remove solids from outlet 26, and cyclone separators may treat the withdrawn and circulating gases.  In another embodiment, not illustrated, solids are carried on an endless grate through a preheater, reactor and cooler with gas circulation as above.
