Title: Improved process for the manufacture of pyroxylin or other cellulose ester sheet material
IPC: C08L1/10
Filed: 1930-04-04
Abstract: Translucent films, suitable for use in making non-splintering glass, are made by mixing pyroxylin or other cellulose ester with sufficient solvent to form a stiff dough-like composition, usually stiffer than bread dough, and extruding it by high pressure as a self-sustaining sheet.  From this sheet the solvent may be evaporated by hot air &c., or dissolved out, or replaced by a volatile non-solvent which is afterwards evaporated; no provision need be made for recovery of the very small amount of solvent used.  A suitable film-forming composition contains 210 lb. pyroxylin, 70 lb. camphor, 175 lb. alcohol, and 17 oz. urea, the camphor being dissolved in the alcohol before mixing with the cellulose nitrate.  It is filtered and then continuously extruded at a pressure which may be 1000-2000 lb. per sq. in.  The extrusion slot may be straight or annular.  A bath for the wet process may contain petroleum naphtha, with enough camphor to prevent extraction of that component from the film, say one pound to each gallon of naphtha.  Finishing, smoothing, and polishing may be effected simultaneously with the wet treatment; the finishing may be done as in Specification 353,045.ALSO:A composition for the manufacture of films suitable for use in making non-splintering glass consists of 210 lb. pyroxylin, 70 lb. camphor, 17 oz. urea, and 175 lb. alcohol.  After extrusion of the composition in the form of a continuous sheet, the alcohol is removed by evaporation, solution, or replacement by a volatile non-solvent which is afterwards evaporated.

Title: Heterogeneous artificial filaments and methods for producing said filaments
IPC: D01D5/28
Filed: 1969-02-28
Abstract: 1,248,293. Making artificial fibres. KANEGAFUCHI BOSEKI K.K. 28 Feb., 1969 [29 Feb., 1968; 30 July, 1968 (2); 8 Oct., 1968], No. 10950/69. Heading B5B. A heterogeneous filament comprises a fibreforming material dispersed in another fibreforming material incompatible therewith in a nebular configuration containing at least 50 "stars" in any cross-section of the filament, the nebular configuration extending along the length of the filament. The whole or a part of the crosssectional area of the filament may have said configuration. In the latter case the part having the nebular configuration and the other part may be disposed in conjugate side-by-side relationship or in conjugate sheath-core relationship which may be eccentrically or concentrically conjugated. The mutually incompatible components of the filament may be a polyamide and a polyester, a polyamide and a polyalkylene oxide or a polyamide and a polyolefin. The polyamide may be nylon-6 or nylon-66. The polyester may be polyethylene terephthalate, polyethylene oxybenzoate or poly-1, 4-bis(hydroxymethyl)cyclohexane terephthalate. The polyalkylene oxide may be polyethylene oxide. The filament may be produced by subjecting at least two molten fibreforming polymers which are not mutually miscible to at least eight joining and dividing steps in different phases to layer multiply the polymers and then melt-extruding the resulting mixture from an orifice in a spinneret. Before extrusion from an orifice of a spinneret, the layer-multiplied material may be conjugated with a stream of another molten film-forming polymer. The term "nebular configuration" is defined as a configuration in which at least one component is irregularly dispersed in the other component in the form of circles, ellipses or other similar shapes, in various sizes and shapes in a manner similar to the disposition of stars in a nebula. A film-forming material is judged to be incompatible with another fibre-forming material if when the two materials are conjugate melt spun the resulting conjugate filament when drawn or bent splits up to form fibrils. In an example, nylon-6 having an intrinsic viscosity of 1À15 in meta-cresol at 30‹ C. and polyethylene terephthalate having an intrinsic viscosity of 0À45 in meta-cresol at 30‹ C. are mix spun by means of two spinnerets as shown in Fig. 19. One of the spinnerets has three distributing plates and the other twelve. Both spinnerets are maintained at 280‹ C. The molten nylon-6 is fed to the reservoir 1 and the molten PET to reservoir 2 by means of gear pumps at equal rates by weight. Both the melts are joined and divided through the distributing plates and layer-multiplied. They are then extruded through orifices 105 into air to form filaments which are cooled, solidified and drawn at a draw ratio of 3À9 on a snubbing pin maintained at 90‹ C.

Title: Method of manufacturing Semiconductors Device
IPC: H01L23/29
Filed: 1967-03-09
Abstract: 1,187,611. Etching. MATSUSHITA ELECTRONICS CORP. 9 March, 1967 [23 March, 1966], No. 11068/67. Heading B6J. [Also in Division H1] In making a semi-conductor device a layer of oxide is formed on the surface of a semiconductor body and an opening etched in it using the photo-resist technique. A second layer of oxide is formed over the first layer and in the opening and then a photo-resist film with an opening corresponding to that in the first oxide layer is applied and the oxide beneath the opening removed by etching in a fluid which etches the oxide of the second layer faster than that of the first. In one embodiment, Fig. 3, using a 500 ohm. cm. P-type silicon wafer, the first layer 2 is formed by heating the water under specified conditions in dry oxygen, and the second layer 3 of phosphorusdoped oxide formed in a diffusion process in an atmosphere of oxygen and phosphorus oxides. A mixture of hydrofluoric and nitric acids is used to etch the hole in layer 3 without undercutting the photo-resist. In a similar method using an N-type wafer both layers are formed by the pyrolysis of an organo-oxysilane which in the formation of the second layer is doped with boron. Reference has been directed by the Comptroller to Specification 1,142,405.

Filed: 1939-04-13
Abstract: 527,465. Measuring rates of change of pressure. KOLLSMAN, P. April 13, 1939, No. 11170. Convention date, May 6, 1938. [Class 106 (ii)] A rate of climb indicator for aircraft comprises a supporting member for a diaphragm capsule and its indicating mechanism and for a temperature insulating vessel enclosing the capsule, the unit being contained in a cylinderical casing. A vacuum bottle 15 closed by a cork stopper 16 provides a pressure chamber 17 and is enclosed by a casing 10 having a window 13 held by a snap ring 14. A capsule 18 within chamber 17 actuates a spindle 19 through link 22 and crank 24, the spindle in turn actuating through quadrant and pinion 47, 46 the spindle 39 of a pointer 38 moving over a scale 40. The capsule is mounted on a spring cantilever 25 fixed to a support 27 extending from a base plate 28 and may be moved bodily for zero adjustment by the eccentric end 30 of a spindle 29 rotated by gearing 32, 33 from a spindle 36 with a slotted bend 37. The interior of the capsule 18 is connected at 51 through a conduit 50 to the interior of the casing outside the vacuum bottle. The chamber 17 is connected with the space inside the casing through a capillary tube 52. The vacuum bottle is pressed against a rubber jacket 54 by a spring 55. In use, when the instrument moves into an atmosphere of less pressure, the capsule 18 at once assumes the new pressure via conduit 50, but the chamber 17 follows the new pressure slowly owing to the restriction 52. A pressure difference is set up inside and outside the capsule and is indicated. The quicker the device moves up or down the greater this change. A slight leakage of constant amount occurs through the jewel bearing 44. This acts like a slight further restriction 52 and may be allowed for in calibrating the scale. In a modification, a thin partition is placed between the spindle 39 which is shortened and the pointer spindle and both spindles carry similar bar magnets at their contiguous ends by means of which the movement is transmitted to the pointer spindle.
