Title: Apparatus for producing a uniform flow of gas and its use in the drawing of glass sheets
IPC: C03B15/12
Filed: 1968-10-01
Abstract: 1,236,219. Drawing glass sheet. PPG. INDUSTRIES Inc. 1 Oct., 1968 [2 Oct., 1967], No. 46641/68. Heading C1M. [Also in Division F4] In the drawing of glass sheet 10 upwardly from a melt 12 through a drawing chamber 20 and then through a drawing machine/annealing lehr 30, a flow of gaseous fluid is directed towards both surfaces of the glass sheet at a position between the drawing chamber 20 and the drawing machine 30 by a plurality of plenum chambers 50, 50<SP>1</SP> to give a substantially uniform flow across both surfaces, the: flow against the central portions of each surface being at a temperature different from that impinging against the marginal portions and the rate of flow being controlled so that natural convective flow of air currents between the drawing chamber and the drawing machine are substantially eliminated. Each chamber 50 comprises a continuous throat of varying cross-section receiving a flow of gaseous fluid from a burner 60 through an entrance port in rear wall 43 and discharging through an exhaust aperture 51 extending across the full width of the throat, the throat having a first portion with diverging side walls 47 followed by a second portion with parallel walls, the upper and lower walls 45 being parallel and spaced close together relative to the distance apart of side walls 47. A baffle plate-53 extends from side wall to side wall in the second portion of the throat to create turbulence on the upstream side and uniform gaseous pressure at the nozzle aperture 51. Automatic control of the temperature of each gaseous flow is obtained through a thermocouple 66 and of pressure from a pressure probe 99. A series of these chambers 50a to 50e and 50a<SP>1</SP> to 50e<SP>1</SP> extend across the width of glass sheet 10 and are of differing widths as shown and the ends are sealed by an assembly 133 with base-plates 135, shelves 136 and edge plates 134 extending just between the outer chambers 50a, 50a<SP>1</SP> and 50e, 50 e 1.

Abstract: 1,040,290. Melt-spinning. E.I. DU PONT DE NEMOURS & CO. Nov. 26 1963 [Nov. 27 1962] No. 46712/63. Heading B5B. In the melt-spinning of synthetic polymers to form filaments, in which the molten polymer before extrusion passes through a filter medium of high surface area, oxygen is removed from the filter medium before molten polymer reaches it and is kept free from oxygen until spinning is begun. Preferably, a filter pack containing a particulate filtering medium is used and oxygen is removed by flushing the filter with a gaseous, inert oxygen-free medium, e.g. nitrogen, carbon dioxide or steam. The filter may be pre-heated in an oven while it is being flushed with a gaseous inert oxygen-free medium. A filter pack containing a particulate filtering medium may be assembled with a spinneret plate, a small amount of solid carbon dioxide placed inside the pack, and the pack pre-heated in an oven. Examples describe the spinning of 6-6 nylon.

Abstract: 1,246,139. Manufacture of integrated circuits. NORTH AMERICAN ROCKWELL CORP. 17 Oct., 1968 [18 Oct., 1967], No. 49384/68. Heading H1K. A structure for use in the manufacture of integrated circuits has a monocrystalline insulative substrate bearing a plurality of semiconductor regions separated by isolating sidewalls borne by or forming part of the substrate. Circuits including diodes, transistors and passive components may be formed by normal diffusion techniques and interconnected by metal deposition across the flat surface of the structure. Substrate materials used are sapphire, magnesia, beryllia, spinel and chrysoberyl. Sidewalls may be formed of three materials or of silicon oxide. Silicon is the semi-conductor of the embodiments; germanium and gallium arsenide are suitable. In one embodiment a silicon oxide layer is deposited on a sapphire substrate, annealed to densify and vitrify it, and masked and etched to form sidewalls. Silicon is deposited overall (and between the sidewalls is epitaxial with the substrate) and the surface mechanically or chemically polished to remove material from the top of the sidewalls. In other embodiments the substrate and sidewalls are formed from an original insulative wafer by removal of material in the areas to be occupied by semi-conductor regions; semi-conductor is then applied by masked deposition. To remove the insulative material a phosphorus-doped oxide or phosphosilicate glass is heated in contact with the insulative wafer and the reaction product dissolved away. One method of applying a layer of the phosphorus-containing material is to decompose TEOS in an oxygencontaining atmosphere in the presence of trimethyl phosphate, trimethylphosphite or triethylphosphate. An alternative method of applying the layer is to deposit a thin silicon layer and to thermally oxidize this in the presence of a gaseous phosphorus-containing material. In each case the layer is then photoresist masked and etched away from the desired location of the sidewalls. The wafer is strongly heated in oxygen and then etched with hydrofluoric acid to remove the reaction product and excess phosphosilicate glass and leave the desired substrate and sidewalls.
