Title: Process for the production of homogeneous rubber deposits from rubber latex
IPC: C09D5/44
Filed: 1926-02-23
Abstract: 257,885. Anode Rubber Co., Ltd. Sept. 4, 1925, [Convention date]. Moulding indiarubber.-The invention relates to the electrophoretic deposition upon metallic bases of homogeneous layers of indiarubber, guttapercha, balata, &c. from latex or artificial dispersions. According to one feature of the invention those ingredients of commercial latex, such as ammonia, which favour the evolution of gas at the anode are partly or wholly removed from the latex before the electric treatment, or are converted into harmless compounds. For example, ammonia may be removed by dialysis, centrifuging, aeration, evaporation, or treatment in vacuo, or it may be converted into less volatile substances by reaction with aldehydes, &c., or by combination with acids, which may be generated in the latex by oxidation of aldehydes. In another modification of the invention latex is used which contains no ammonia but which has been preserved by small additions of bactericides such as thymol, Vucin or eukopinotoxin. According to another feature of the invention the current density is so regulated that the potential produced at the deposition surface is insufficient to cause electrolysis. A further feature consists in coating the deposition base with an absorbent coating such as gelatine or collodion which is impregnated with a coagulating agent. The metals used as anodes are preferably those which continuously ionise and become dissolved during the electrophoretic treatment, such as zinc, cadmium, iron, lead, and alloys thereof. The invention may be combined with or applied to the processes described in Specifications 245,177, [Class 70, Indiarubber &c.] ; 246,532; 253,069, and 254,765, [both in Class 70, Indiarubber &c.]. Specifications 21441/08 and 223,189 also are referred to.

Title: Improvements in mechanism for controlling the speed of a fluid-actuated prime mover, e.g. an air-driven turbine
IPC: F01D17/22
Filed: 1951-03-05
Abstract: 710,095. Air turbines. GARRET CORPORATION. March 5, 1951 [March 20, 1950], No. 5279/51. Class 110(3) [Also in Group XXIX] A speed governor for a turbine 10 driving an alternator 12 and fed with motive fluid e.g. compressed air, through a conduit 14, comprises a valve 22 in the conduit and actuated by a diaphragm 28 controlled by a pilot valve 37 movable by flyballs 41 driven by the turbine through gearing 19, 44. The chamber 26 beneath the diaphragm is connected to a pipe 33 at one end joined through a restrictor 34 to the conduit 14 and at the other end forming a seat 35 for the pilot valve which allows air to bleed from the pipe 33 when the turbine is at the desired speed. Thus should the turbine speed exceed the desired value, the valve 37 will move to permit a larger bleed thus reducing the pressure in the chamber 26 and permitting a spring 30 to move the valve 22 in a closing direction to reduce the speed. Similarly a decrease in speed below the desired value causes the pilot valve to decrease the bleed, thus increasing the pressure in the chamber 26 to move the valve 22 towards open position. The pipe 33 has another outlet 36 forming a seat for a solenoid-actuated valve 38 which may be opened by closing a switch 47 to cause complete closure of the valve 22. In a modification. the valve 38 is movable manually or by an electric motor to permit a constant bleed from the pipe 33 thereby setting the desired speed of the turbine. An electrically-operated stop-valve 48 may be provided upstream of the valve 22. In another arrangement. the valve 37 is arranged to control the supply of air to the chamber 26.

Title: Semiconductor device
IPC: H01L21/20
Filed: 1967-02-08
Abstract: 1,146,943. Semi-conductor devices. SONY CORP. 8 Feb., 1967 [9 Feb., 1966], No. 6606/67. Heading H1K. A semi-conductor device comprises a substrate of one conductivity type and an epitaxial layer comprising single crystal portions of the opposite conductivity type and polycrystalline portions surrounded by diffused regions forming PN junctions with the single crystal portions. As shown, Fig. 3, a layer 12 of N-type silicon is grown on a P-type silicon substrate 10 by decomposition of silicon tetrachloride containing phosphorus trichloride. The N-type layer 12 is monocrystalline except at regions above seeding areas formed on the surface of substrate 10 where wedge-shaped polycrystalline regions 13 are produced. The seeding areas may be grooves 11 formed in the surface or areas of silica deposited on the surface. The wafer is then heated to diffuse acceptor impurities from substrate 10 into epitaxial layer 12. Since the impurities diffuse faster through the polycrystalline regions 13 than through the monocrystalline part of layer 12 a P-type layer 14 is formed which completely surrounds the polycrystalline regions 13. Electrodes may be applied to the upper and lower surfaces to produce a variable capacitance diode. In a modification, Fig. 4 (not shown), the substrate and epitaxial layer are both of N-type conductivity and an acceptor impurity is diffused into the surface of the epitaxial layer instead of diffusing the impurity out of the substrate. This produces a surface P-type layer (16) which extends down the sides of the polycrystalline regions (13). An integrated circuit can be produced by planing down the surface of the device shown in Fig. 3 to expose the polycrystalline regions 13, Fig. 5 (not shown). Alternatively the deposition of the epitaxial layer can be stopped before the polycrystalline regions (13) are completely covered. Devices such as transistors, diodes, capacitors, and resistors can be formed in the monocrystalline regions and are electrically isolated from one another by the PN junctions surrounding the polycrystalline regions (13). In further modifications a P-type epitaxial layer is deposited on a P-type or an intrinsic substrate provided with seeding areas and a donor impurity is diffused through the substrate or epitaxial layer respectively into the polycrystalline regions.

Abstract: Epoxide resins, i.e. glycidyl ethers obtained by the reaction of a polyhydric aromatic compound, formed by the condensation of a phenol with a ketone or an aldehyde, with a compound having a glycidyl radical or a compound capable of yielding a glycidyl radical under the condensation reaction conditions are hardened by an alkyl substituted mono-nuclear aromatic diamine containing two primary amine groups attached directly to the aromatic nuclus. The alkyl substituents contain 1-5 C. atoms and more than one alkyl group may be substituted in the nucleous; m-toluylene diamine is specified.  An epoxide resin was prepared by heating a solution consisting of 11.7 parts water, 1.22 parts NaOH and 13.38 parts diphenylol propane to 70 DEG  C. and then cooling to 45 DEG  C. and adding 14.06 parts epichlorhydrin.  The product was washed and dried in vacuo to give a viscous liquid resin; 10 gs. of mixed isomers of m-toluylene diamine were added to 100 gs. of the resin and a product having a pot life of 8 hours at room temperature was obtained which was suitable as a bonding medium for glass cloth laminates or for potting electrical components.  A second resin was obtained by reacting phenol and paraformaldehyde in presence of boron trifluoride-ethyl etherate to give a phenol-formaldehyde condensate which was reacted with epichlorhydrin in presence of alkali.
