Title: Improvements in electrical socket connectors and other electrical contact devices
IPC: H01R24/58
Filed: 1963-04-18
Abstract: 1,087,861. Two-part couplings; binding posts. SEALECTRO CORPORATION and S. T. DEAKIN. April 16, 1964 [April 18, 1963], No. 15400/63. Heading H2E. [Also in Division B6] An electrical connector having an insulating body 10 has a contact formed as a metallic coating on the body and associated with a separately constructed resilient contact 15 is secured to part of the coated contact at 16 so that a co-operating contact is gripped between it and part of the coated contact. In the embodiment shown in Fig. 1, annular support 10 is formed of a photo-sensitive glass plate. Sockets 11 are made in the plate by covering it with a negative exposing it to ultra-violet light and etching with hydro-fluoric acid. Copper strips 12 and the linings for the holes 11 are then printed on the surface by any of the known techniques used for decorating china. Further contacts 15 are then etched in linked form, Fig. 2 (not shown), from a sheet of rhodium-plated beryllium copper or beryllium nickel using conventional etching techniques, and welded on to the copper strips 12 at 16, after which the ties 14 between them are removed and their ends 17 are bent to lie within the copper-plated holes 11. A cover-plate 20 is then formed with holes 21 in a similar manner, and the two plates are riveted together through holes 22. Plug pins or wires can then be inserted and gripped in copper-lined holes 11 by contacts 17. The whole assembly may be mounted in an aperture in a printed circuit board and contact ends 23 soldered to the printed tapes. A stack of plates may be mounted vertically above one another with contacts only in some of the holes 11, Fig. 3 (not shown). When pins are inserted some of the pins make contact with the coated sockets of one plate and others with those of other plates. Thus the ends of metal strips 12 are staggered at different levels for ease of connection. The sockets may be arranged in rows, the contact strips being originally produced in the form of a grid, Fig. 5 and 6 (not shown). In a further embodiment, Figs. 7 and 8 (not shown), a plug of the type shown in Fig. 8 fits into a central aperture of the socket connector and pins (46) fit between the copperplated contacts (38) and the etched contacts (42), lip (45) being formed to provide guide surfaces for the pins.

Abstract: 943,262. Maintaining vehicle height constant. DUNLOP RUBBER CO. Ltd. May 2, 1960 [May 6, 1959], No. 15463/59. Heading B7D. In a height control system for a road vehicle having pneumatic suspension, the rate of flow between the levelling valves 10, Fig. 1, and the springs 6 is reduced at will or automatically to prevent excessive loss of air when the vehicle is in motion by means of an intermediate flow control valve 11 which is remotely operated through a fluid pressure system sensitive to the motion of the vehicle. In one example, the valve 11 is operated to restrict flow by fluid pressure supplied from the hydraulic dampers 11 when the vehicle is travelling at speed. Alternatively, the valve is operated manually through a solenoid-operated valve system or is operated automatically by pressure derived from an automatic gear-box which develops sufficient pressure when the vehicle reaches a predetermined speed.

Title: Improvements in high frequency electrical oscillators
IPC: H01J25/587
Filed: 1942-11-04
Abstract: 590,549. Magnetrons. OLIPHANT, M. L. E., and WRIGHT, C. S. Nov. 4, 1942, No. 15574., [Classes 39 (i) and 40 (v)] In a magnetron of the kind in which a plurality of coupled resonators of the same natural frequency are thrown into oscillation by direct reaction with the electron stream, the main cathode operates by secondary emission and an auxiliary thermionic cathode provides initial primary bombarding electrons, a control grid being located adjacent to the auxiliary cathode to control emission of electrons therefrom and thus to control also the output of the magnetron. In the form shown the main cathode 5, Fig. 2, is surrounded by a number of cylindrical resonators 3 machined from a single block and the primary cathode 12 is located in one of the coupling end spaces 7. The control grid is in the form of a tantalum disc 13 provided with perforations 14, Fig. 3, opposite the cathode 12. A cap 16 surrounds the back of the cathode. Energy is taken from one of the resonators by an antenna connected to coaxial line 9. The main cathode may be formed of a layer of caesium or one or more of the oxides of thorium, aluminium, calcium, barium, strontium or beryllium, of the silicates of barium, upon a metallic base of molybdenum, tantalum, aluminium or copper-beryllium alloy. In one form the cathode is of aluminium, preferably coated on a copper member, provided with a thin oxide film by cleaning it in caustic soda solution and subsequently heating in boiling water. Alternatively, copper-beryllium alloy _may be oxidised to, form a thin layer of beryllium oxide thereon. Cathode 12 may be of tungsten with or without a coating of alkaline earth oxide. During operation of the device electrons returning to the cathode 5 produce further secondary electrons and the device may thus be made self sustaining so that the energisation of the cathode 12 is not required to keep it in operation ; if in this case it is desired to stop operation, for example in keying the magnetron to produce short highfrequency pulses, the anode potential must be momentarily reduced to zero. Alternatively, if the bombardment by return electrons is insufficient to maintain the device in operation, the de-energization of the cathode 12 will stop operation of the device. In a modified form the resonators are rods disposed circumferentially around the cathode and coupled together by common end rings or a common central ring. Resonators may be arranged in a straight line facing a flat cathode. Specifications 588,185 and 588,186 are referred to.

Filed: 1977-04-15
Abstract: In the process, the exhaust air is guided in an absorption stage (100) countercurrent to water. The water absorbs the solvent continuously. Subsequently, in a downstream desorption stage (200), the water is removed from the solvent by continuous azeotropic distillation. The scrubbing water treated in this manner is fed back to the absorption stage. In rectification stages (300, 400, 500) downstream of the desorption stage (200), the solvent is separated even more completely from the water and purified. <IMAGE>
