Title: Improvements relating to prepayment electricity and other like meters
IPC: G07F15/08
Filed: 1940-11-23
Abstract: 542,858. Prepayment mechanism for electricity, gas and like meters. CHAMBERLAIN & HOOKHAM, Ltd., JAMES, S., and DEACON, L. O. Nov. 23, 1940. No. 16838. [Class 27] Means for varing the rental charge or the quantity of commodity available for a given coin comprises an axiallyimmovable spindle a rotated by a motor b, a clock, or a coin carrier, a driven member d loosely mounted on the spindle and adapted to operate a switch, valve or like member, means p fixed to the spindle for disconnectibly driving the driven member d, a rotatably-adjustable stationary cam u for connecting and disconnecting the means p and the member d, and a spring m for returning the member d to an initial position after each disengagement. In the construction shown the spindle a is driven by a motor b through gearing c, and the member d is normally held in one position by a spring m, a stop n on the member d abutting an adjustable stop o. As the spindle a is rotated one side of a spring-loaded axially-movable detent s on a disc p fixed to the spindle engages a pin t on the member d and drives the member forward until the other side of the detent enters a notch y in the normally stationary cam u whereupon the detent disengages from the pin t and frees the member d so that the latter is returned to its zero position by the spring m. The angle through which the member d is rotated at each revolution of the spindle a thus depends on the angular portion of the cam u. This cam is secured to an adjustable dial or index v set by hand to any desired position, and is retained in position by a spring-loaded pawl w engaging a ratchet wheel x secured to the cam. The member d may, as shown, form a gear wheel meshing with a gear operating a switch (not shown); This gear is loose on a shaft f to which ratchet wheels g, h are fixed, a pawl being mounted on the frame k and engaging the wheel h to prevent backward rotation of the shaft. The other ratchet wheel is engaged by a pawl mounted on the gear e so that the wheel g and shaft f are driven in one direction by the gear e. In a modification the disc p is axially-slidable on the spind e a and has a fixed detent projecting from each face thereof, one adapted to engage the pin t on the member d and the other the recess y in the cam u.

Abstract: 545,507. Secret transmission. AKT.-GES. BROWN, BOVERI, & CIE. Nov. 23, 1940, No. 16841. Convention date, Oct. 2, 1939. [Class 40 (iv)] In a system in which elements of a message are differentially delayed. and transmitted in a jumbled sequence, the message is submitted to two jumbling plans with different and preferably incommensurable recurring periods with the aid of the same delaying apparatus. For example, the message elements are recorded in accordance with a pre-selected plan with the aid of a distributer U1, connecting- field A1 and group of recording magnets B11 .. B14 on a telegraphone tape and are picked up for transmission to line with a further shuffling of the order with the help of a group of reproducing magnets B21 ... B25, connecting- field A2 and distributer U2. The timing may be such that each reproducing magnet picks up a whole element or a part of two elements. In another arrangement, a disc is used instead of a tape. The same apparatus can be used for two-way working with the respective messages passing through the jumbler in the same or in opposite directions. The telegraphone may be replaced by an equivalent electrostatic or electro-optical record. Thermionic, rectifier, or cathode ray distributers may be used at U1, U2. Additional secrecy apparatus'of the same or another type may be employed. According to the Specification as open to inspection under Sect. 91, electrical delay networks or acoustic delay tubes may be used instead of a telegraphone. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of multi-part leads for vacuum tubes and the like
IPC: H01J9/28
Filed: 1945-07-06
Abstract: 595,577. Making leading-in wires for vacuum tubes. STANDARD TELEPHONES & CABLES. Ltd., and FITCH, C. K. July 6, 1945, No. 17302. [Class 83 (ii)] In making multi-part leads for vacuum tubes or the like which are sealed through the envelope thereof, means are provided for making one or more parts of the lead from lengths of wire stock with both ends of the parts conically shaped to facilitate welding or use. The said means is preferably combined with the welding device, means being also provided for feeding the parts automatically as they are severed from the wire stock into position for welding to another part of the lead so that reels, coils or lengths of wire to provide the sealing piece and extension piece can be fed direct to the welding device without a separate earlier preparatory operation being necessary to make ready the doubly pointed extension member. The extension members 2 which are doubly-pointed so as to be welded to a sealing part 1 of smaller diameter and also so as to be plugged into a socket without an adapter, are made by feeding wire 6 by a reciprocating gripper comprising a fixed chuck 8 and chuck 9 mounted on a traversed slide through a guide 10 under a rotary cutting or grinding disc 16 to form grooves 20 successively along the wire. The cutter is mounted on a slide 19 which is moved intermittently towards and from the wire and the end portion 22 of the wire is seized by a non-rotary gripper 21 carried by a slide 23. The chucks are rotated by a belt 13 during the grooving operation and the end section 22 which is held by the gripper 21 is thus broken off and is then transferred by movement of the slide 23 to a position opposite a component 24 made in the lead making mechanism 5, where welding is then effected by electricity and by a flame 25.

Title: Improvements in and relating to free wheel brake hubs
IPC: B62L5/00
Filed: 1935-06-17
Abstract: 441,373. Coaster hubs. FICHTEL & SACHS AKT.-GES., Schweinfurt, Germany. June 17, 1935, No. 17404. Convention date, June 16, 1934. [Class 136 (ii)] In a coaster hub of the type in which the driver or a part connected therewith is adapted to be locked in position when the brake is applied, so as to avoid continuous back-pedalling, a driving connection so constructed as to allow the braking- effect to be varied is provided between the driver and a locking- member which normally rotates but is fixed during back-pedalling. A disc s is screwed on the outer end of the driver a and is provided with an annular extension g, which receives in a recess the outwardly-bent end h<1>, Fig. 2, of an annular locking-spring h, the free end of which has several inwardly-directed teeth engaging corresponding teeth on the periphery of a locking-disc i. On the inner periphery of the disc i is a recess to receive an outwardlyprojecting lug k on an annular spring l, which has a frictional driving engagement around an annular projection on a nut m engaging a threaded part of the fixed bearing cone u. The rotation of the nut m in either direction is limited by the engagement of one of two spaced stops o thereon with a finger n on a ring clamped between the cone u and a protecting-cap x on the axle d, the friction spring l slipping when the nut is thus held. On back-pedalling, the parts s, h, i, rotate the nut m, which then clamps the friction spring l against a flange on the cone u, thus locking it and the other parts to relieve the back-pedalling action. To increase the braking action, further backpedalling is applied, whereby the teeth of the spring h are forcibly displaced by one or more teeth along the periphery of the disc i. On the resumption of forward pedalling, the spring h grips the disc i so that the teeth cannot spring apart, and the parts resume their normal position. In a modification, the spring ring h and the friction spring l are of somewhat different form, and the bearing cone u is divided to facilitate assembly.

Filed: 1948-07-15
Abstract: 647,397. Door locks. PARKES & SONS, Ltd., J., and BUTTER, F. J. July 15, 1948, No. 17424/49. Divided out of 647,372. [Class 44] In a latch of the kind operable from the inside by a knob and from the outside by a key lock, means are provided external to the latch case to lock the knob by reverse rotation of the key. Figs. 4 and 5 show the locking mechanism in sections at right angles. The latch bolt 2 is retracted by a drag link 3 connected to a cross pin 4 carried in a crank arm 5. The key lock connecting bar 20 engages, with 90 degrees of lost motion, in a quadrant opening 19 in a rotary barrel 18 which carries a projection engaging with 270 degrees of lost motion in a second rotary barrel 17. A spring plunger 12 secures the pin 4 in position and engages dn a circumferential slot 16 in the barrel 17 providing further angular lost motion. A projection on the end of the barrel 17 extends into an opening 25, Fig. 6, in a sliding locking plate 26, so that backward rotation of the barrel, as the result of reverse rotation of the key through more than a complete revolution, lifts the plate to engage a locking lug 32 in a notch in the segment plate 40 carried on the shaft of the inside knob 38 which is thereby locked. The provision of the angular lost motion allows the key to be withdrawn in its normal angular position and leave the sliding plate 26 in the locking position. The cross pin 4 projects through an arcuate slot in a mounting plate 8 and is engaged by a horn 41 of the segment 40 on the knob spindle for normal retraction. The locking plate 26 is slidably mounted on headed studs 30 engaging key-hole slots 31 Which prevent removal of the plate in the locking position. Studs 33 projecting inwardly from the cover plate 28 are slotted to engage the plate 26 in the locking position and prevent removal of the inside knob even when the fixing screws of the cover plate are removed. The locking plate 26 may be operated from the inside by a thumb knob 37 and is yieldably retained in either position by a springloaded detent 35 engaging in notches 36. Specification 647,372 is referred to.

Title: Improvements in short-wave wireless transmitting arrangements
IPC: H04B7/155
Filed: 1929-06-07
Abstract: 331,667. Lorenz Akt.-Ges., C. March 27, 1929, [Convention date]. Relaying systems; directive signalling; multiplex signalling; signalling to aircraft. - In short-wave wireless signalling, intermediate stations Z1, Z2 are arranged between a transmitting-station S and a receiving-station E to relay or alter the direction of the electromagnetic waves in such a way that no obstruction lies in their path. In flat country the intermediate stations are at the same height h above the. ground, but in hilly districts they are arranged at different heights on hills as may be convenient (Fig. 7, not shown). The waves are passed on without amplification by a flat reflecting-surface (Fig. 2, not shown), a reflecting prism (Fig. 3, not shown), or by interconnected receiving and transmitting bi-pole aerials, each at the focus of a parabolic reflector (Fig. 4, not shown). Alternatively an amplifier is arranged between the receiving-aerial and the transmitting-aerial (Fig. 5, not shown). Several signalling-channels may be provided by using different wave lengths or waves polarized in different planes, for example by arranging the bi-pole aerials at right-angles in the two channels (Fig. 6, not shown). Beacons for signalling to aeroplanes or the like are provided near each station.
