Title: Multiple electric switches
IPC: G05G7/08
Filed: 1963-06-12
Abstract: 993,814. Keyboard switches. C. M. G. DU T. DE ROUGEMONT, and M. STAPFER. June 12, 1963 [June 16, 1962], No. 23314/63. Heading H2B. A plurality of various push-button operated switches 21, 22, 23, are assembled on a single channel-shaped carrier member 6 by means of projections 12 engaged in bayonet slots 14 in the flanges of the carrier member and a lug 20 on the latter is bent down to retain the switches in position against one another. A gap is left between the front of the switch bodies and the base of the channel, a spring- urged bar being slidable therein to engage notches 32 in some of the operating members 9 to provide interlock. Switches not thus interlocked have independent locking means (not described). A lug 20 may be provided adjacent each slot 14 such that switches may be individually retained in position with spacing therebetween (Fig. 4, not shown).

Abstract: 405,359. Compressing tea, coffee, &c. to form tablets. PHILLIPS ENGINEERING CO., Ltd., Evelyn Road, Sparkhill, Birmingham, and WOOD, C., Goulston Street, London. Aug. 20, 1932, No. 23419. [Class 87 (ii).] Tea, coffee, or other powdered or granular material is compressed in moulds to form tablets, the moulds being carried by, or formed in a rotary which is supported by tie rods n and distance pieces m between end plates a, b either or both of which is or are provided with teeth whereby drive may be imparted to the structure by pinions e, f, on a shaft g driven by belt and bevel gearing. The end plates, and mould plate revolve about a fixed central shaft c which carries stationary cams s, 3 whose edges engage rollers r, 2 located at the joint of toggles q, w, these toggles being connected at one end to one of the end plates a, b and at the other to plungers o, v which operate in the moulds b to compress the powder and eject the moulded tablets. The plungers o, v are fitted with rollers t, 4 which engage cam tracks u, 5 to retract the plungers, the toggles being positively broken by projections 11, 27 which engage rollers 10, 28 on the cam tracks. The cams u, 5 are provided with ramps such as 20 to engage the projections 11, 27 and break the toggles should the structure be rotated in the wrong direction. The fixed cam 5 has a spring pressed pivoted member 6 forming part of its track to ensure that the ejectors v are retracted to their lowest position. The cam 3 is fitted with a radially adjustable toepiece 25, Fig. 4 opposite the charging position to regulate the effective depth of the mould cavity, the material being charged into the moulds by a fixed hopper 9 having a mouth resting on the mould plate k. After the material has been compressed, the tablets are ejected and are then swept off to a shoot by a fixed blade 12. The surface of the table k is cleaned between the discharge and charge positions by a fixed brush. Specification 357,194 is referred to.

Abstract: 1,176,292. Coating with gold. ENGELHARD MINERALS & CHEMICALS CORP. May 16, 1968 No.23448/68. Heading C7F. A gold decorating composition used to produce a gold coating by thermal decomposition of a gold mercaptide comprises an organic gold mercaptide dissolved in an organic vehicle containing 1-100% by weight based on the weight of gold, of a free halogen selected from iodine, bromine, and interhalogen compounds of iodine and bromine, iodine and chlorine, or bromine and chlorine. The gold mercaptides may comprise gold resinates, cyclic terpene mercaptides, or primary, secondary or tertiary gold mercaptides of alkyl, cycloalkyl or aralkyl mercaptans, preferably containing 1-20 carbon atoms in the molecule. The solvent may include mixtures of essential oils, terpenes and resins and the composition may include a gold flux such as salts or resinates of Bi, Pb, B, Si, Cr, Cd, Sn, Cu, Co, Sb, U. Salts or resinates of Ag, Pd or Pb may also be included. The halogen may be added to the composition prior to the coating process or it may be introduced as a gas during the firing. The substrates coated are plastics such as cellulose acetate, wood, paper, textiles and glazed porcelain. The halogen lowers the decomposition temperature of the mercaptide.

Title: Super-regenerative wave-signal translating system
IPC: H03D11/02
Filed: 1947-08-25
Abstract: 643,347. Super - regenerative receivers. HAZELTINE CORPORATION. Aug. 25, 1947, No. 23466. Convention date, Sept. 24, 1946. [Classes 40 (v) and 40 (vi)] In a super-regenerative receiver having a separate quench oscillator a voltage developed from the quench oscillation supply dependent upon the amplitude of the quench oscillation is applied to the super-regenerative amplifier to offset variations in quench oscillation amplitude. As shown, the receiver comprises an amplifier valve 10 regeneratively connected to a tuned circuit 11, 12 coupled to the aerial and a detector valve 41 connected to the anode circuit of the valve. The quench voltage is generated by a separate oscillator valve 25 and applied through a capacitor 32. Part of the self-bias developed across grid resistor 29 is applied through resistor 35 to the grid of valve 10 to compensate for changes in the amplitude of the quench oscillation. In an alternative and more effective arrangement (Fig. 2, not shown), the compensating bias is obtained from a similar connection but the quench oscillation obtained from the grid is used as the anode supply for the super-regenerative amplifier. It is also suggested that the bias may be obtained by separately rectifying the quench oscillation.

Fig. 5 shows another arrangement in which a support plate 29 is provided for the liner 5. The plate is perforated at 30 to allow the insertion of raised portions 31 of the liner to pass through and be held. The portions 31 are arranged in staggered fashion so that rollers 9 pass evenly over them. Other forms of reinforcing are described in connection with Figs. 6, 7 (not shown) including canvas strips.

Leather sealing strips 82 secured to the cap 44 are fitted to prevent oil flowing upwards towards the drill shank. To permit the discharge of cuttings and oil flowing upwards from the drill point, radial slots 86 are cut in the body member in alignment with the flutes the slots act as a centrifugal pump aiding the withdrawal of cuttings and oil. The device may be pressed against the work by a spring 60. In a modification, Fig. 10, the recesses 30<11> are of semicircular form, the communicating holes 62<11> from the oil chamber are drilled in the body member and the sealing means comprises balls 102 in holes 100 slightly restricted at the inner ends so that the balls can project sufficiently to seat in the recesses 30<11> under the oil pressure acting through apertured plugs 104 ; the cap 44", which has no ears, has projections modified to fit the semicircular recesses. As applied to rotating work, Fig. 8, the sleeve 64 is omitted and fluid is supplied through branch pipes 94 connected to a flexible tube 98 that permits a small amount of rotation of the body as the drill is fed into the work. When. the device is used as a drill bush by setting it in a jig, roller bearings may be fitted between the sleeve 64 and body 34.
