Title: Semiconductor devices
IPC: H01L21/331
Filed: 1960-08-04
Abstract: 959,447. Junction transistors. RADIO CORPORATION OF AMERICA. Aug. 4, 1960 [Aug. 24, 1959], No. 27116/60. Heading H1K. A transistor is formed from a semi-conductor wafer of one conductivity type having on one face a surface layer of the opposite type produced by diffusion and forming a gradual junction with the rest of the wafer. Impurity is diffused into both wafer faces to form a thin high conductivity layer of the opposite type on each face and then leads are attached to each layer and to the part of the wafer of said one conductivity type. A typical transistor of this type is made from a wafer of 1-20 ohm cm. P-type germanium by masking one of its surfaces, immersing it in germanium powder doped with 4 X 10<SP>16</SP> atoms/c.c. of antimony and heating to 800‹ C. for an hour. Masking may be effected by heating the wafer for 10- 15 minutes at 700‹ C. in a current of argon containing triethoxysilane, the latter decomposing to form a silicon oxide layer which is then removed except from one face by treatment in 5% hydrofluoric acid. Alternatively, during the heat treatment one face of the wafer is protected from the gas flow by being stuck to a glass plate. After removal from the doped powder the wafer is reheated in nitrogen to 850‹ C. for 20 hours to produce a gradual PN-junction 34 (Fig. 3b) by further diffusion. The masking layer is then etched away and the wafer immersed in a powder consisting of 95% by weight germanium and 5% arsenic and heated for an hour at 800 C. in a nitrogen swept furnace to form an N+ layer over its entire surface. After etching the wafer to the form shown in Fig. 3d, the collector region 35 is attached to copper header 17, Fig. 3e, with lead antimony solder. A ring-shaped base contact 13 of indium-coated nickel and emitter contact of nickel coated with tin lead are then attached to connect the respective zones to wires 15, 16 sealed through the header, and the device encapsulated. The use of silicon, silicon germanium alloys, and alloys of phosphorus, antimony and arsenic with aluminium, gallium and indium instead of germanium is suggested.

Patent GB-880406-A (GB)
Title: Production of condensation products of alcohols
Inventor: MCLEAN ANDREW
Filed: 1957-08-30
Abstract: Higher ketones or such ketones and carbinols are prepared by dehydrogenating a lower aliphatic or cycloaliphatic monohydric secondary alcohol having not more than 6 carbon atoms in the vapour phase at an elevated temperature by contact with a supported nickel catalyst in the presence of an organic hydrogen acceptor capable of being hydrogenated under those conditions in which the aliphatic or cycloaliphatic alcohols are dehydrogenated, and recovering the higher ketones and/or carbinols from the reaction mixture.  The hydrogen acceptors are compounds which apart from accepting hydrogen, otherwise take no active part in the reaction and include ethylenically and acetylenically unsaturated hydrocarbons, aromatic hydrocarbons and quinone.  The proportion of hydrogen acceptor to alcohol may vary from, for example, 1:4 to 4:1.  Some of the lower alcohol is converted into the corresponding lower ketone and the latter may be recovered and recycled with fresh lower alcohol feed. Dehydrogenation may be effected at 100 DEG -300 DEG C., if desired in the presence of inert diluents such as N2 or paraffins.  The preferred catalyst is nickel-on-kieselguhr, pretreated with hydrogen at 200 DEG -400 DEG C. and then with steam at 150 DEG -300 DEG C. The products may be isolated by condensation followed by fractional distillation.  Examples describe the dehydrogenation of isopropanol using benzene or a mixture of pentenes sometimes containing pentane, as the organic hydrogen acceptor and the higher condensation products include methyl isobutyl ketone, di-isobutyl ketone and methyl isobutyl carbinol in addition to acetone and other condensation products; comparative experiments are described using no hydrogen acceptor, the yields of higher ketones and carbinols being reduced or wherein acetone replaces the isopropanol, the produce then being mainly mesityl oxide.

Abstract: 337,892. Gilbert, W. V. Dec. 8, 1928, [Convention date]. Aeroplanes; planes, arrangement and construction of; controlling.-Aeroplane wings of which the camber and dihedral angle can be varied in flight each comprise a main spar C braced towards its outer end by auxiliary spars A, B, articulatively connected to the main spar C, means being provided for controlling or adjusting the relative position of the inner ends of the spars. The inner ends of the spars A, B are articulatively connected to sleeves I, K, respectively, adapted to slide on a longeron, links E, F, or ribs maintaining the spar C at its correct distance from them. The movement of sleeves I, K is restricted so as always to maintain the inner end of spar C above those of spars A, B. The inner end 4 of the main spar C is linked by an extension D to an apex joint 5 to which is similarly connected the extension of the main spar of the complementary wing. Links G, H connect the joint 5 to sleeves I, K. Thus alteration in the camber produced by movement of sleeves I, K causes variation of the dihedral of the wings. In a modification, Fig. 4, the extensions D on opposite sides are approximately collinear and links H are omitted, variation of dihedral being effected by causing the longerons or guides for sleeves I, K to approach or recede from one another by mechanism such as shown at L. Both the sleeves I and K may be operated or one pair only operated and the other allowed limited movement against spring-operated stops. The guide for the moving sleeve may be arranged at an angle to the wing chord at its inner end so that a change in camber also causes a change in incidence. The wing ribs may be flexible or be formed in two parts and hinged about the longitudinal axis of spar C.
