Title: Improvements in electric lamp holders
IPC: H01R33/46
Filed: 1928-07-20
Abstract: 324,349. Pullon, J. R. July 20, 1928. Holders.-An approximately cylindrical insulating block is divided into two portions d, e, Fig. 2, having reduced or enlarged extensions which engage between inwardly or outwardly extending lugs c formed integrally with a bayonet socket a, one portion d of the block having recesses i to receive contact pins j and the other portion e closing the recesses, the contact pins being retained therein by the pressure of the block portions. Flats f on the block and the lugs c may have ribs g and grooves h in order to register the block axially; slots and projections may be also provided to ensure correct circumferential position. The block portions may be registered relatively to each other by the provision of grooves and ribs and the block and ring may be tapered upwardly. A conductor k may be threaded through holes drilled in different axial planes in the contact pins and the end of the conductor may be attached in any manner to another part thereof so as firmly to secure it to the pins. Alternatively, circumferential, spiral, longitudinal or transverse slots may be cut in the pin. A slot may be cut so as to form a resilient tongue. The slots and holes may be dispensed with, the conductor being held against the pin by the block portions. The pins may be held in clips provided with holes or slots for the conductors. Both portions of the block may be recessed to house the pins and the recesses may be of a tapered. angular or wedge shape. The conductors k may be gripped in channels l, in which transverse ribs may be provided, but, preferably, they are given free play therein. The block members may be secured together by a screw. In a modification, a holder which may be screwed to a wall-fitting has the block members formed with enlarged extensions and a space may be provided at the enlarged end to house surplus wire.

Abstract: 974,085. Gear pumps and motors. FRANK G. HOUGH CO. June 12, 1961, No. 21104/61. Heading F1F. A gear pump or motor comprises three pairs of meshing gears mounted on parallel shafts 20, 21, each central gear 15, 18 rotating in the opposite direction to its corresponding outer gears 14, 16, or 17, 19. The width of the central gears is equal to the sum of the widths of the outer gears, to balance the transverse forces on the shafts, and the bearings 22, 23, 36, 38 which support the shafts may therefore be less substantial than shown. The two shafts are connected by a gear train 45, 40, 44, and rotate in the same direction. The gears, and the walls 24, 26, 28, 30 separating them are urged together by the flange 32 on the cover plate 31, or by springs or fluid pressure.

Abstract: 1,182,496. Two-part couplings. J. S. PUTYATO, A. M. MEDVEDENKO, A. V. MARTSINKEVICH and E. B. ASHURKOV. 8 May, 1967, No. 21339/67. Heading H2E. Complementary socket and plug connector parts 1, 2 comprise arrays of contact-carrying insulating plates 6, 12 interleaved with springs 14 and retained on bars 5, 11 by end plates 3 and 4, 9 and 10, the registration of parts 1, 2 on engagement being facilitated by co-operating projections 33 and recesses 34 on end plates 3, 9 respectively. Pressure between contact blades 13 and socket contacts, which comprise opposed blades 7, 8, is produced by tightening a nut 20 on the threaded end of a rod 16 against a pressure plate 18 whose two parts 17, 22 are linked by projections 19 and recesses 23 on. coupling the connector. Tightening of the nut 20 resiliently pulls together the contactcarrying plates 6, 12 in each connector part and forces projections 26 on each plate 6 against the socket contacts of an adjacent plate 6, thereby closing the socket contact blades 7, 8 around the contacts 13. A cover 32, for housing terminal connections and which includes a cable grip, is secured to one of the connector parts by screws.

Building boards are secured against the web-remote face of flanged supporting laths by latches mounted on the ends of the webs of board stiffening laths, the latches being spring urged to engage over the web-adjacent face of the flanges of the supporting laths when the boards are pressed into position against the laths. In one form, see Figs. 1 and 2 in which the boards themselves are not shown, a latch plate d pivots in a slot cut in the upstanding flange of an angle section board stiffening lath b secured, for example as described in Specification 530,192, to the hidden face of the building board, the tail part of the latch being pulled by a spring d' towards the lath b, causing the other end to engage over a flange of an inverted, sheet-metal supporting lath a to secure the board against the other side of the flange. The latch is released by the longitudinal movement of a plate e in a slot in the web of lath a, the ends of the plate pushing the latch clear of the flange, to the position shown, in dotted line in Fig. 1. The plate is moved by a blade inserted between the adjoining edges of the boards and into the space between the sides of the web of lath a. In a modification, see Figs. 7 and 8, the latches consist of blade springs f spotwelded to the board stiffening laths b.

Abstract: 320,437. General Electric Co., Ltd., and Wilson, W. July 26, 1928. Drawings to Specification. Running-in after assembly. - Fluid-pressure engines, in particular internal - combustion engines for motor-cars, are run-in by electric motors which start slowly and are controlled automatically so as to increase the speed when the frictional resistance diminishes. After a determined speed has been reached, the engine is started and the electric motor is converted into a braking generator for the purpose of testing the adjustments of the engine and of measuring its power-output. The Specification describes the electric motor control arrangements in which automatic acceleration is obtained in part under time-limit control and in part under current-limit control. The timing device may be a, drum driven from the machine through reduction gearing. Specification 316,384, [Class 38 (v), Electric switches &c.], is referred to.

The electrode may be a tapered pin connected to a needle valve controlling the material flow or embedded in the insulating nozzle assembly. All metal within the barrel and nozzle assembly is insulated from the air with the exception of the electrode. The material may be sprayed hydrostatically or pneumatically, air being discharged through horns 14, 15 in the latter case. The flexible cable 26, which may be coaxial, is supported by clamps 28, 31a, the spray material is supplied through conduit 32 and air through conduit 31. A trigger 21 controls the gun valves in the case of manual operation; the gun may alternatively be operated automatically, the gun being mounted on an insulating support and the coating material, such as paint, being supplied through a high electric hose, e.g. nylon tubing. Safety means in the power supply prevents the potential end current exceeding certain limits. One end of the source 30 connects the article 17 to be coated to earth.

Abstract: 239,242. Telefunken Ges. f³r Drahtlose Telegraphie. Aug. 30, 1924, [Convention date]. Frequency, changing.-In means for obtaining alternating current of a lower frequency from a source of higher frequency current by the use of iron-cored static transformers, a plurality of circuits arranged on a common core are made of such a character that their natural frequencies are related to each other by a straight line law. In the arrangement shown in Fig. 1 in which the core is magnetized by a direct current, winding, the frequency of the generator circuit w is equal to the sum of the natural frequencies of the circuits w1 and w2. When direct current magnetisation is not employed, the frequency relationship w1+2w2=w may be obtained. When the frequency w1 is only slightly less than the generator frequency w, w2 may be a beat frequency. The Specification as open to inspection under Sect. 91 (3) (a) also states that the frequencies w and w1 may be obtained in a single circuit tuned to the frequency w1 but acted upon by the. generator oscillations of frequency w. This subject-matter does not appear in the Specification as accepted.
