Title: Carrier current telegraph system
IPC: H04L5/06
Filed: 1929-09-25
Abstract: 340,301. Wired-wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London. -(Western Electric Co., Inc. ; 195, Broadway, New York, U.S.A.) Sept. 25, 1929, No. 29027. [Class 40(v).] In a carrier-current telegraphic system with terminal stations interconnected by a transmission circuit 1, 2 and subscribers' loop circuits 11, 15 connected to each terminal station through a balanced bridge 9, a source of carrier current 10 is connected to the neutral points 31 of the bridge, and a key 12 is provided at the subscriber's station to unbalance the bridge, and the carrier-current signals are transmitted over the transmission circuit and over the subscriber's loop 15 to relays 16, 18, which control a direct-current receiver 19. When the sending-key is open, current from the oscillator 10 at the central station divides equally at the terminals 31 of the hybrid coil 9, and no resultant current is induced in windings 28 which are connected through a filter 7 to the transmission line 1. With the sending-key closed, an artificial line 13 is short-circuited, and more current flows in the windings 27 than in the windings 26 with the consequence that current of the oscillator frequency is transmitted over the line to a distant station. At the distant station the signalling current flows through a transformer 4, a band-pass filter 14, and the receiving-loop 15 to the alternating- current relay 16 at the subscriber's station. When the signalling-current moves the relay to its marking- position M, a circuit is completed from a battery 20 through the armature and back contact of the relay 18 and the telegraph sounder 19 to earth, thus operating the sounder. A plurality of subscriber's stations are similarly connected to conductors 5, 6 through different band-pass filters. According to modifications : only three conductors connect each subscriber's station to the central station, and the hybrid coil is connected through a transformer to one of the conductors, which is arranged differentially and at the subscriber's station connected through a transformer with the sending-key and the artificial line (Fig. 2, not shown) ; a single two-conductor loop extends from the central station to each subscriber's station, where a pair of high-frequency currents are combined and the resulting difference frequency operates the relay (Fig. 3, not shown) ; a threeconductor loop is used to each subscriber's station, the oscillator is connected through a transformer to the central lead, which is connected to midpoints of the primary windings of transformers at the central and subscriber's stations respectively, and the key is inserted in another of the leads (Fig. 4, not shown) ; the oscillator and the key are connected in the central lead (Fig. 5, not shown).

Title: Improvements in hydraulic couplings and change speed gears
IPC: F16H39/24
Filed: 1922-10-26
Abstract: 189,110. Wingquist, S. G. Nov. 16, 1921, [Convention date]. Clutches and speed-varying mechanism.-Relates to hydraulic couplings and variable-speed gears comprising one or more pumps of the piston or sliding-vane type, and consists in means for automatic control so that the most suitable transmission ratio is obtained at any moment. In the form shown in Figs. 1 and 2, the driving- shaft 1 carries a rotor 2 co-operating with a rotor 5 on the driven shaft 3 and with rotor bodies 6, 7 carried by sleeves 10. 11 provided with pawls 12, 13 co-operating with ratchet teeth in a frame 15, so that the bodies 6. 7 are prevented from rotating oppositely to the rotor 2. A partition 16 secured to the rotor 2 supports the casings of valves 20, 21, 22, the pairs of valves being linked to rings 35, 36, 37 mounted on a sleeve 38 projecting from the partition, and the outer ends of the valves 20, 21. being always subject to the pressure generated in the pump 2, 5. Safety valves 44 are also provided. With the driving-shaft at rest, springs 42 press the valves 22 into position to establish communication between the pressure and suction chambers of the pump 2, 5. When the driving-shaft rotates at or above a first predetermined speed, the valves 22 are moved outwards centrifugally to close this communication, a pressure, will be established in the pump 2, 5 and the shaft 3 will be driven at the same speed as the shaft 1 if the load on the shaft 3 be a light one. When the load increases, so that the liquid pressure on the valve 20 exceeds the centrifugal force acting on the valve, the valve is moved inwards, so as to open communication between the pump 2, 5 and the pump 2, 6 and a transmission ratio is established. A second ratio is established when the valve 21 is similarly operated. When the driving-shaft exceeds a. second and greater predetermined speed, the valves 20, 21 are moved outwards by centrifugal force and a direct drive is established. In modifications, the rotors 2, 5 are carried by the driven and driving shafts respectively, so that the centrifugal force acting on the valves is that due to the speed of the driven shaft; or two sets of valves may be employed, one controlled by the driving and the other by the driven shaft.

Title: Improvements in machines for measuring leather and hides
IPC: G01B5/26
Filed: 1921-11-03
Abstract: 171,101. Defrance, J. E. A. Nov. 5, 1920, [Convention date]. Surface areas, computing.-In the usual leather-measuring machine provided with a totalizer, the latter is arranged independently of the other members of the machine, and a shaft driven at a speed proportional to the speed of the feeding roller is adapted, by means of an electromagnetic device, to operate the totalizer only during passage of the leather, The leather passes between the feed-roller 2 and a series of rollers 11 carried by levers 12 mounted on knife-edges 15 and acted upon by springs 13 which tend to keep the rollers 11, 2 in engagement. The movement of the roller 11 is transmitted to the totalizer by electrical means involving the use of a shaft 8 driven through reducing gear from the roller 2. When the rollers 11, 2 are separated by the leather, contact is made at 22, 23 for the electrical circuits of magnets 25 which attract one end of a lever 29 pivoted on a knife-edge at 30, the other end of the lever moving a rack 9 into engagement with a toothed wheel on the shaft 8 against the influence of a spring 33. As long as leather is passing under the roller 11 the movement of the rack continues and this movement is transmitted to the totalizer. The spring 33 acts as a pawl to retain the rack in the position to which it has been moved when the electrical contact is broken upon the rollers 11, 2 again engaging. After a measurement has been effected, the parts are restored to normal by pulling on a cord 39 which turns a balanced shaft 36 carrying arms 34, 35, which release the spring 33 and restore the rack.
