Abstract: 1,193,868. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 28 June, 1967 [30 June, 1966], No. 29878/67. Heading H1K. [Also in Division C7] An ohmic contact is formed on a semi-conductor, e.g. silicon, substrate by first forming a layer of Pt or Al on the substrate and then sputtering layers of Mo and Au. The Au may also contain Pt by making the cathode of an Au-Pt alloy or with a Pt coating. A wafer 70 having a transistor on the left-hand end and a resistor on the right-hand end and an oxide coating 69, has the oxide coating removed at the contact positions, and a layer of Pt is evaporated over the whole surface. The substrate is heated at 700 C. to form platinum silicide at the contact positions, and the substrate is then boiled in aqua regia to remove the Pt on the oxide surface, leaving platinum silicide parts 81. The Mo layer 77 and the Au or Au-Pt alloy layer 78 are then sputtered, and an overlying Au layer 79 evaporated. The metal layers are then selectively removed to produce the desired pattern of contacts and interconnections.

Title: Improvements in and relating to apparatus for stabilising the current in an electric load circuit
IPC: H05G1/44
Filed: 1949-11-24
Abstract: 682,688. Automatic current control systems. GENERAL ELECTRIC CO., Ltd., COOPER, M., and DUNHAM, C. R. Nov. 24, 1950 [Nov. 24, 1949], No. 30160/49. Class 38 (iv). [Also in Group XL (b)] The current in a D.C. load circuit is stabilized by a valve in series with the load, the voltage drop across a cathode resistor being compared with a reference voltage and the resultant being applied to the control grid. As applied to stabilizing the voltages of the dynodes of an electron-multiplier photo-electric cell (see Group XL (b)), an H.T. supply 10 supplies a load consisting of resistors 11 ... 20 in series with a triode connected valve 21 and cathode resistor 22. The control grid is maintained at a steady potential by a gas-filled stabilizer tube 23 fed through a resistor 24. A resistance 25 having a value equal to the value of the cathode resistance multiplied by the amplification factor of the valve is connected between the cathode and the H.T. supply.

Title: Improvements in or relating to the control of variable attenuation of networks for alternating signalling or like systems
IPC: H04B3/20
Filed: 1935-11-01
Abstract: 465,464. Two - - way transmission. TELEPHONE MANUFACTURING CO., Ltd., BURRIDGE, B. J., and PADDLE, L. H. Nov. 1, 1935, No. 30253. Addition to 442,947. [Class 40 (iv)] [Also in Group XL] The system described in the parent Specification which involves the application of control voltages derived by rectifying A.C. signals from two sources to different points of a multi-branch circuit for the control of attenuation networks deriving their normal bias voltages from such circuit is modified by amplifying the signals before rectifying and applying the control voltages in direct opposition to each other and simplifying or omitting the multi-branch circuit. As shown in Fig. 1 control signals on circuits S1, S2 are amplified and rectified and produce voltages across resistances R3, R4 acting in opposition on the networks N1, N2. Signals from S2 also operate a relay X which short-circuits itself. Normal bias for the rectifiers is supplied by battery BT. In one modification only one, and in another neither of the networks has an initial bias. In another arrangement, Fig. 4, the control signals act on four networks N1 .. N4 which may have different initial bias so that they change their state in a predetermined order. A further arrangement, Fig. 5 (not shown), resembles that shown in Fig. 4 but the transformers T3, T4 have separate secondaries for N1, N2 and N3, N4. In a further modification, Fig. 6, adapted for very weak signals, the valves V<1>, V<2> amplify alternating current from a local source such as AC1 and the incoming signals either block or unblock these valves, the output from which is rectified and controls the networks as in the other systems. The circuit VC automatically limits the value of the resulting currents.

Abstract: 208,149. Limon, F., (Assignee of Picard, R.). Dec. 5, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Whistles.-A fluid-pressure whistle has an annular bell 1, through the central orifice 2 of which the operating fluid is projected. The fluid jet may be annular of cylindrical (Fig. 3), conical (Fig. 20), or polygonal shape, or may be a solid cylinder of any desired regular or irregular shape. A core 3, Fig. 3, may project more or less into the outlet 5 which may be divergent as shown or cylindrical. The whistle may be used for directional signalling by mounting it with its axis horizontal so as to be rotatable about a vertical axis, or upon a universal mounting; by terminating the outlet 5 in a horn which may have oppositely-projecting mouth portions or may be subdivided by partitions so as to have a cellular formation; or by providing a reflector 9, Fig. 20. In order to vary the note given, the height of the bell may be varied by screwadjusting means, Fig. 15, or by the construction shown in Fig. 16 which may be used for code signalling and in which a spring-controlled piston member 10 is operated by rods 12. The bell may be provided with adjustable orifices to cause a further variation in the tone and to prevent accumulation of water in the bell. In order that the whistle may give several notes simultaneously, the bell may comprise several chambers 14, 15, 16, Fig. 18, of different volume. The Specification as open to inspection under Sect. 91 (3) (a) states that the outlet 5 may also be convergent or any combination of divergent, cylindrical and convergent, and that the principle of a double-acting whistle, which is a feature of whistles according to the invention since that part of the fluid which at first passes into the bell also operates the whistle upon escaping, may also be applied to whistles of ordinary type by causing the fluid which passes into the bell to pass through a suitable orifice when it escapes into the atmosphere. This subject-matter does. not appear in the Specification as accepted.
