Abstract: 941,474. Switchgear structures. GENERAL ELECTRIC CO. Ltd. Oct. 27, 1961 [Oct. 27, 1960], No. 36944/60. Heading H2B. In electric switchgear comprising a stationary part 1 carrying a fixed terminal 8, an earth terminal 21 and a bus-bar terminal 18, the latter two terminals are alternatively movable into spout 15, so that the two connector contacts (not shown) of the movable part 6 of the switchgear can engage the fixed terminal 10 and one of the other two terminals. The earth terminal comprises an arm 21 pivoted at 20, and the bus-bar terminal comprises a piston 18 slidable in a sleeve 17 connected to one of the bus-bars 16, the two terminals being interlocked so that they cannot occupy the spout 15 together. Auxiliary bus-bars 3 are provided, to which the movable part of the switchgear, e.g. a drop-out circuit-breaker, may be connected. The fixed terminal 8 is connected to a combined cable and voltage transformer terminal 12 through current transformers 11. Although a three-phase bus-bar system is shown, any number of phases may be employed.

Title: A method of manufacturing a diffusion type semiconductor device
IPC: H01L21/00
Filed: 1960-10-27
Abstract: 910,857. Semi-conductor devices. SONY CORPORATION. Oct. 27, 1960 [Oct. 29, 1959], No. 37000/60. Drawings to Specification. Class 37. A semi-conductor device is made by depositing a first impurity on the surface of a semiconductor body, heating in an oxidizing atmosphere to diffuse the impurity into the surface and simultaneously form an oxide film on the body and subsequently removing part of the film and diffusing a second impurity into the exposed part. To form a NPN transistor an N-type silicon wafer is heated in boron oxide vapour at 700-1100‹ C. to form a deposit of boron which is subsequently diffused into the wafer to form a P-type layer by heating at 1000-1300‹ C. in an oxidizing atmosphere for 1-2 hours. An oxide layer is formed at the same time by the reaction with the atmosphere which may consist of wet oxygen, hydrogen or nitrogen or dry oxygen. Part of the oxide layer is then removed by the photo-resist method and donor impurity diffused into the exposed P-type layer to form an N-type layer thereon.

The sheath may be uniform throughout, and be made of metal, ceramic glass or silica, or have a metal end separated from the body of the sheath by a ceramic ring 7 as in Fig. 2 or have a ceramic end sleeved over the ends of a metal sheath (Fig. 3 not shown). After filling the sheath 1 about the resistor 3 with mineral insulating powder 4 and vibrating to compact the powder, the glass is added (Figs. 4-7 not shown). A layer 4a of the same or a different insulating powder may first be added to reduce the glass penetration time in forming the seal, Fig. 9. The inside of the end of the sheath (when of metal) and the surface of the terminal 6 are oxidized prior to addition of the glass. Glass may be added as a powder 5a and melted in situ (Fig. 6, 10 not shown) or as a liquid. The end is maintained at 800‹C for 30 minutes. The element may be cooled in liquid nitrogen between the ends being sealed, so that in use there will be a pressure of interstitial gas of up to 4 atmospheres within the sheath. This improves heat output. Materials used are: sheath 1, metal, quartz glass, crystallized glass, ceramics; insulating powder, alumina magnesia mica of 40-200 mesh; terminals, iron soft steel, stainless steel; glass, B 2 O 3  -SiO 2 -BaO, PbO-B 2 O 3 -ZnO.

Water-soluble amine salts of α-aminobenzylpenicillin suitable for penicillin therapy are prepared by suspending hydrated-amino-benzyl penicillin in an organic solvent, adding a primary, secondary or cyclic amine to cause the α-aminobenzylpenicillin to dissolve, filtering the resulting solution and treating the filtrate with anhydrous magnesium sulphate to remove water therefrom, filtering a second time and treating the dewatered-filtrate to recover the desired water-soluble amine salt of α-aminobenzyl penicillin. Alternatively, the alkali metal salts may be obtained by adding to the dewatered filtrate a solution of (a) an alkali metal salt of a carboxylic acid, e.g. sodium salt of 2-ethyl hexoic acid; (b) an alkali metal oxide of an alcohol or phenol, e.g. sodium methoxide or sodium phenate; (c) an alkali metal iodide; (d) an alkali metal nitrate or (e) an alkali metal thiocyanate.

Filed: 1964-09-25
Abstract: In a process for producing a moulding material, a binding agent is prepared by acid hydrolysis of a silica ester.  A refractory material, e.g. metallic zirconium, is added and the acidity of the binder is reduced by addition of a metal oxide which reacts with the hydrolysis acid to form a salt insoluble in the moulding material and insoluble in the binder solution HCl, H2SO4 and H3PO4 are suitable acids and AgO, BaO or an iron oxide may be used in neutralization.  A more readily hydrolysed silica ester may be added to the hydrolysed silica ester and a metal oxide used which reacts with the hydrolysis acid to form a water soluble salt which is insoluble in any non-aqueous diluent present.  The first ester may be condensed ethyl silicate and the more readily hydrolysed ester methyl silicate.  From 0.05 to 0.5% by weight of metal oxide (based on the weight of moulding material less the refractory) may be used.
