Title: Air conditioner
IPC: F24F5/00
Filed: 1953-09-28
Abstract: 744,557. Cooling air; refrigerating. GARRETT CORPORATION. Sept. 28, 1953 [Oct. 20, 1952], No. 26576/53. Classes 29 and 64(3). Air to be supplied to an enclosure 13 is cooled in a heat exchanger 10 by coolant air which previously is cooled by expansion in a turbine 24 and afterwards is acted on by two fans 25, 38 the second of which has means for varying the flow through it, and so varying the cooling effect of the coolant air in the heat exchanger. In the form shown, these means comprise a pre-swirl device 39 in the inlet of the fan 38, which is motor-driven. The pre-swirl device has vanes which are angularly adjustable manually or automatically by changes in the temperature of the enclosure 13. Alternatively, throttle valves may be provided or the speed of the fan 38 may be variable. The first fan 25 is driven by the turbine 24. The coolant air is bled through a passage 23 from air being cooled in the heat exchanger, and flows successively through two passes 20, 21 in the latter. Water is sprayed through nozzles 26, 27 into the coolant air before it enters the passes 20, 21, to increase the cooling effect. To prevent ice-formation by excessive cooling, a byepass 34, regulated by a valve 35 controlled by the temperature of the coolant air entering the heat-exchanger, supplies uncooled air to mix with the cooled air entering the turbine 24. Water is also sprayed in an automatically controlled amount through a nozzle 31 into the cooled air, to keep the humidity in the enclosure 13 constant.

Title: Method of making a semiconductor device
IPC: H01L21/283
Filed: 1969-05-28
Abstract: 1,263,980. Making semi-conductor devices. MATSUSHITA ELECTRONICS CORP. 28 May, 1969 [5 June, 1968; 12 Aug., 1968 (2)], No. 26948/69. Heading H1K. In most embodiments manufacture of semiconductor devices utilizes the fact that whereas a deposited film of palladium or high palladium alloy will adhere strongly to a metal or semiconductor surface it has only low adhesion to silicon oxide and will peel away from this when exposed to an atmosphere containing hydrogen. In one process palladium is deposited on to a silicon body covered with an apertured silicon oxide layer and is then exposed to a hydrogenous atmosphere. A gas blast will then blow away palladium except that in contact with the silicon. Aluminium may be deposited and patterned to complete the contact. (A Schottky barrier or ohmic contact may be formed in dependence on the resistivity of the silicon). In another process an aluminium contact is formed within an apertured silicon oxide layer and also overlies the surrounding oxide. Palladium is deposited over the entire surface and stripped with hydrogen except where it overlies the aluminium. A gold wire may be thermocompression bonded to the palladium. In a further process palladium is deposited through and on to a silicon oxide layer and the deposit is covered with aluminium. That part of the palladium overlying the oxide is then pulled away carrying with it the overlying aluminium. In a different embodiment a process is suggested in which a metal other than Pd but which similarly has poor adhesion to silicon oxide is coated over an apertured oxide layer and is itself coated overall with Pd. Exposure of the structure to hydrogen then lifts the Pd and other metal only in the region where the composite coating overlies oxide. In the above methods aluminium alloys, gold, or nickel may replace aluminium.

Title: Improvements in electrical musical instruments
IPC: G10H3/26
Filed: 1934-09-19
Abstract: 442,379. Electrical musical instruments. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and LEWER, S. K., c/o General Electric Co., Ltd., Wembley, Middlesex. Sept. 19, 1934, No. 26953. [Class 88 (ii)] The strings 1 of an electrical musical instrument are all maintained continuously in oscillation by arranging each of them in a constant magnetic field 3 and passing through all or groups of them, a common alternating current containing components of a frequency corresponding to each of the strings. The current is derived from condenser pick-ups 4, feeding a common amplifier 6. Notes are sounded in the loud-speaker 11 by keying variable-condensers 9 connected to condenser pick-ups 5, the operation of a key serving greatly to increase the capacity of its condenser 9, so that the corresponding pick-up 5 effectively feeds the amplifier 10. Alternatively, the pickup 5 may be directly approached to the string for keying. Transients can be produced by controlling the rate of increase of capacity during keying. The strings may be of tungsten. The Provisional Specification states also that the quality of the note can be changed by varying the position and /or shape of the pick-up 5, and /or by inserting solid dielectric between it and the string.

Title: Improvement in a process for manufacturing an expanded steel member
IPC: B21D47/02
Filed: 1957-08-27
Abstract: 863,877. Making expanded metal members; bending; rolling; shearing. WATANABE, H. Aug. 27, 1957 [Aug. 30, 1956], No. 26977/57. Classes 83 (2) and 83 (4). In a method of making an expanded steel member two alternately-arranged series of longitudinal slits are cut in the web of a channel by rolls to prepare a lattice member and repeated deforming operations are carried out, each consisting of a rolling and a subsequent expanding, said rolling extending the lattice member longitudinally and said expanding being laterally directed by longitudinal diverging guides, which engage flanges of the channel, the expansion being such that the necessary extension in the lattice member never exceeds the extension imparted to that member by the previous rolling operation. A steel channel 10, Fig. 2, is cold-rolled from a tube in four passes and then passes between cutting-rolls 30, 32 and 34, Fig. 3, which slit the web intermittently along two lines 14, 16. Recesses 38 and 40 spaced at 180 degrees on the periphery of the upper rolls discontinue the slit at alternating points in adjacent lines, these points subsequently forming connections 20, 22 between a lattice member 12 and side members 24, 26. The member 12 is extended cold by four pairs of rolls, e.g. 50, 52, the lower rolls being of larger diameter than the upper rolls. After each rolling the lattice member is expanded by continuous diverging guides 42, 44 which engage flanges 46, 48 of the channel. The amount of extension imparted to the lattice member 12 at each rolling is at least equal to that required for its increased length at the next stage of the expansion or may be such that an excess extension is provided to allow for variation in the thickness of the stock. In either case during expansion the' lattice member is always slack. After expansion the latticed member 10<SP>1</SP> passes through a leveller 58 and a flange straightener 60 having axially adjustable rolls 62, 64. To produce an X-formation latticed member the slitting rolls are modified to include further cutting edges.

Filed: 1954-09-17
Abstract: 757,282. Measuring air-speed and yaw. KOLLSMAN INSTRUMENT CORPORATION. Sept. 17, 1954 [April 6, 1954], No. 26997/54. Class 40(1) A system on a helicopter for indicating the air-speed a n d preferably also the yaw angle comprises one or a pair of petot tubes (not shown) mounted at the end(s) of an arm driven at a constant speed of e.g. 3600 r.p.m. and acting on preferably piezoelectric transducers 21. The output of the transducer(s) is passed by a cathode follower adjacent the rotary arm, a transmission line and a filter 25 to amplifiers 27, 28. The output of the former amplifier is rectified and governs the reading of a meter 29 calibrated in air-speed. The latter comprises a current-limiter tube 254 and a clipping pair 267 and is coupled by a cathodefollower 284 with an inductance in its output circuit to the coil 325 of a phase meter 357. The other coils of the meter are fed with currents in quadrature from a generator 31 driven at the same speed as the arm carrying the petot tubes. The reading on this meter gives the yaw angle, since the peaks of the sinusoidal wave generated by the transducer occur at the points in the rotation at which the pressure ducts translation of the aircraft is a maximum.
