Abstract: 1459596 Crimping tools AMP Inc 16 March 1974 11774/74 Heading B4W [Also in Divisions H2 and B3] Wire 6 is connected to a ferrule 10 on a terminal by crimping the ferrule on to the wire and ramming the wire end axially into the ferrule with a twisting action. Apparatus for performing the method may comprise a benchmounted tool or machine or, a hand-operated tool (Fig. 1) of the toggle or cam type, e.g. as in Specification 918,577. In addition to dies 34, 36, 38, 40 for crimping the ferrule and a steel sleeve 15 to the insulation 8, holding dies 35, 41 are provided for gripping the end of the ferrule. Mounted by fasteners 48 on the crimping machine is a cylinder 50 housing a plunger 52 with a conical end 58. A sloping surface 62 on the head 50 of the plunger 52 is pressed by a spring 61 against a similar surface on an abutment 64. After the ferrule has been crimped, rotation of the head 50 by a rod 72 forces the rotating plunger into the wire end, Fig. 5, to weld some of the strands to each other and to the ferrule. Solid aluminium wires also may be crimped, the terminal being of soft metal such as aluminium, copper or tin-plated copper. Alternatively, the terminal may be made from composite stock of copper and aluminium, the width of aluminium providing a lining for the ferrule. The ferrule may have a welded or brazed seam, or a U-shaped terminal may be used, Fig. 7 (not shown), with offset arms (80) for engaging the wire end.

Title: Improvements in or relating to picture transmission, television and like systems
IPC: H04N7/08
Filed: 1930-04-16
Abstract: 348,343. Copying telegraphs. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. April 16, 1930, No. 12114. Convention date, April 20, 1929. [Class 40 (iii).] In copying-telegraphy or television, particularly for short waves, two or more objects 10, 11, Fig. 4, or parts of the same object modulate two or more scanning beams of light, which are sequentially interrupted and influence photo-electric means 12, 13 to produce modulated carrier waves equal in frequency but displaced in phase, and at the receiver, Fig. 6, the signals are synchronously distributed in correct phase to build up the image or images. As shown two illuminating beams are interrupted alternately by a rapidly rotating perforated disc 3, but more than two beams may be employed (Fig. 5, not shown). The signals are distributed to light sources 17<11>, 18<11> by a commutator 11<11> driven from a motor 13<11> controlled by a tuning fork 5<11>. Current produced by this fork is compared with current from a similar tuning fork at the transmitter in the plate circuit of a thermionic valve 2<11>, and a difference in phase causes increasing or decreasing anode current to switch a relay X and thus cause a motor 7<11> to move a differential gear 8<11> backwards or forwards to correct the synchronism of the commutator. Alternatively the multiple of the carrier frequency automatically produced may be used to drive a small synchronous motor on the same shaft as a synchronous motor driven by a local tuning fork and the main driving motor (Fig. 7, not shown). The invention may be applied to television (Fig. 8, not shown). The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of a commutator in the circuit of the photo-electric cells instead of the light-interrupting disc (Fig. 5, Cancelled, not shown). This subject-matter does not appear in the Specification as accepted.

Abstract: 791,919. Claw clutches. DAIMLER-BENZ AKT.-GES. April 27, 1955 [April 27, 1954], No. 12188/55. Class 80 (2). The teeth of the axially slidable member of a synchronized dog clutch are formed as radial spoke-like elements 39 carried in a ring 35, such teeth having squared inner ends 41 sliding in axial grooves 28 in a shaft-mounted hub 25, and lozenge-shaped intermediate zones engageable with facial teeth 60 on the axially-fixed complementary clutch member 22, to be clutched to the hub 25. The clutch has a combined synchronizing and balk ring 46, frictionally engageable externally with one dog clutch element 22, and having circumferential movement with respect to the complementary hub element 25 limited as by clearance teeth 55, 33 on the balk ring 46 and hub 25 respectively. The balk ring 46 has pointed teeth 51 engaged by the sliding clutch teeth 39. For selecting direct or geared drive in a countershaft change-speed gear driven by a fluid coupling, disengageable clutch or slip clutch, there are two dog clutches comprising input members 22, 27 alternatively clutchable to an output shaft 23 through the single clutch ring 35. The hub 25 has annular recesses at both ends accommodating the dog teeth 60, 61 of the clutch members 22, 27. In operation, axial thrust, applied by a shift-fork 43 to the clutch-ring 35 in one or other direction, e.g. leftwards, loads the balk-ring 46 axially through blade detent-springs 56, to engage the synchronizing cone surfaces, whereby asynchronism causes the input clutch member 22 to drag the balk-ring 46, e.g. clockwise, arrow X, Fig. 11, to the limit of the clearance 2e, whereupon the lozenge tooth portions 39 of the clutch pins engage the pointed ends 54 of the balk teeth 51 on the ring 46, thus increasing axial synchronizing pressure. On completion of synchronism, the balk-ring 46 is turned back by the teeth 39, 54 riding up into mesh as the detent-springs 56 yield, permitting final mesh of the tooth portions 39 with the pointed facial teeth 60 of the clutch member 22:

Abstract: 578,368. Transmitting mechanical power; automatic control systems. WINTHER, M. P. Sept. 27, 1941, No. 12550. Convention date, May 5. [Class 38 (iv)] Current ; torque ; speed. A three - phase motor 3 drives a load shaft 9 through an eddy current coupling 15 and the torque during starting or running and the motor load current are limited to or maintained at an adjustable maximum by controlling the excitation of the coupling. Maximum acceleration under load is attained without overloading the motor. Two half-wave, gas-filled rectifiers RT may supply the excitation coil CL and a grid voltage in phase with anode volts is furnished by a transformer GT feeding into resistances GB. A current transformer LT feeding into a resistance potentiometer P gives an adjustable voltage determining acceleration opposed to the former whereby the rectifiers cut off at the limiting value of motor current or torque which is read on an ammeter AM. A governor switch GV responsive to load shaft speed may introduce resistance or adjust a carbon pile in the primary circuit of transformer GT to cut off the normal grid voltage and control the speed. In. a modification a second pair of valves with a different anode voltage is parallelled with the first. The grid circuits of all valves are fed with D.C. voltages derived from three separate rectifiers one of which furnishes suitable fixed but adjustable biases, another a bias cut off, by the opening of governor switch contacts and the third bias which is in an adjustable ratio with the load current. In this modification time delayed switches are inserted in the anode supply to the valves and in the circuit of the current transformer.

Filed: 1921-05-02
Abstract: 162,660. Soc. GÚnÚrale des Freins Lipkowski. May 3, 1920, [Convention date]. Fluid pressure.-In accelerator valves for compressed air brakes, of the kind comprising a piston or diaphragm subject to the opposing pressures in the train-pipe and a control chamber and at each successive reduction in train-pipe pressure actuating a valve to vent the train-pipe to a chamber, the compressed air in the control chamber is allowed to escape to the atmosphere to effect the rapid return of the valve after it has been actuated. The pressure in the chamber B connected to the train-pipe at a is normally equalized through the passage c with the pressure in the chamber c and a small reservoir connected at b, and the parts are thus maintained in the position shown by the spring F with the venting chamber G connected to atmosphere by the passages d, e and slide valve H. When the train-pipe pressure is reduced the passage c being insufficient to equalize the pressures above and below the diaphragm D, the valve H uncovers the passage d to vent the train-pipe to the chamber G and connects the passage f from the chamber C to the exhaust passage d. When by the escape of air from the chamber C both through the passages c, d the pressure therein falls sufficiently. the spring F'returns the parts again to the position shown.
