Filed: 1926-01-04
Abstract: 268,859. Lanchester, F. W., and Lanchester's Laboratories, Ltd. Jan. 4, 1926. Cores; coils; commutators.-The winding o of an armature of the Gramme or ring type is threaded through holes in the core-laminations a so as to be held in place without wedges &c., the return connections being taken as a single layer through the interior of the ring or through perforations in the laminations near the inner edge of the ring. The armature thus wound is pressed in a hydraulic press to flatten the wire, or it may be wound with rectangular wire. The armature is gripped between a plate g mounted on the spindle n and a plate h which holds its commutator f. For this purpose the plate h is formed with two tapered grooves into which fit two rings u formed of wedge-shaped segments, so that on drawing the rings together by screws v the inner edge of the flange, in which are sawcuts, grips the commutator f, a layer s of insulation being interposed between them. In a modification only one set of segments is employed and the inner flange is formed as a separate piece. Each section of the winding is constructed of a single length of wire and the ends of the sections are serrated to interlock and bound with wire which is connected to the risers from the commutator segments. In a modification a double layer is carried through the interior of the ring; in this case the armature is not compressed but the portions of the winding at the sides of the ring are embedded in a plastic insulating cement.

Comprises steering gear for a heavy vehicle in which an axle housing 4 is steerable ,about a pivot or universal connection 6 to the vehicle frame 5, the steering movement being imparted to the axle through steering gear 8, 24 mounted on a torque rod 10 connected to the frame and pivoted at 13 to the axle. In the construction shown the steering gear comprises a screw shaft 8, mounted in bearings on an arm 14 fixed to the torque rod, and a nut 24 slidably engaging arms 22 on a block 21 connected by arms 20 to the axle housing 4. The shaft 8 is operated by the driver through a universally jointed shaft 29 and bevel gears 27. The torque rod is connected to the frame by a universal joint, not shown, in line with the universal joint 30 in the steering shaft 29. Both axles of the vehicle may be steered in the same manner, and the two steering screws 8 may be operated simultaneously or separately. Either or both axles may be driven; in the latter case they are preferably driven from a central gear casing and forwardly- and rearwardly-extending propeller shafts having universal joints 19 at their axle ends and other joints at their inner ends close to the universal joints of the torque rods. One or two engines may be used to drive the axles. The axis of the axle, and the pivots or joints 6, 13, 19 are located in different transverse planes of the vehicle, the axle pivot 6 being nearer the centre of the vehicle than the axle itself, the torque rod pivot being still nearer, and the propeller shaft joint 19 nearest of all to the central transverse plane. The vehicle is preferably of the kind described in Specification 537,619 in which each axle housing is mounted by means of two balance levers on four driving wheels. The inner ends of the torque rods 10 are connected through the arms 14 to stabilizing means as described in Specification 537,619. Specification 537,629 also is referred to.
Patent GB-138957-A (GB)
Title: Improved electric switch for use with burglar alarms
IPC: G08B13/22
Filed: 1919-01-04
Abstract: 138,957. Nissen, G. Jan. 4, 1919. Burglar and like alarms.-A switch for setting a burglar alarm is operated from outside the premises, safe, or the like to be protected, by means of a key which is adapted to move a ratchet-wheel through a predetermined angle for which the key is automatically set when it is withdrawn, so that the door which has been protected can be opened without giving the alarm only by using the key set for the predetermined angle to return the ratchet-wheel to its original position. The ratchet-wheel 2 is mounted on an axle 7 extending through the door or wall to be protected. The key, Fig. 6, comprises an outer cylinder 21 terminating in a ring 20, and an inner cylinder 22 provided with teeth at its end and at its middle part 23. The teeth at the end of the inner cylinder are adapted to engage corresponding teeth 9 on the axle 7. The cylinder 21 has an outer spur 26, adapted to enter a slot and engage a groove 19 in the member 8 in which the axle 7 is mounted, and an inner spur 27 adapted to engage a spur 24 on the inner cylinder. On inserting and rotating the key, the axle and ratchetwheel are rotated through a predetermined angle by the engagement of the spurs 27, 24. The key is then returned to its original position, the inner cylinder, axle and ratchet-wheel being prevented from rotation by the pawl 3. On withdrawing the key, the teeth 23 under the action of a spring 25 engage the spur 27 and lock the inner cylinder in a position corresponding to the angle through which the ratchet-wheel has been turned. When it is desired to enter the premises without giving an alarm, the key is again inserted in the tube 8 and turned until the spur 27 engages the spur 24; on completing the revolution of the key, the ratchet-wheel is returned to its zero position. In the arrangement shown in Figs. 1 and 9, the axle 7 carries a contact-brush 13 which rests on an insulating-segment 12 in the zero position of the ratchet-wheel; in all other positions the brush 13 completes the circuit through a contact-rail 6. in a modification, the ratchet-wheel and pawl form terminals and one of the teeth of the wheel is covered with insulating-material. In applying the invention to a continuous current alarm, Fig. 10, the contact-brush is insulated from the ratchet-wheel and completes a circuit in the zero position. The switch is provided with a cover 10 through which the axle 7 extends, a button 14 on the end of the axle being provided with an indicator to show the position of the switch.

Title: Television receivers
IPC: H03D1/22
Filed: 1973-01-02
Abstract: 1414892 Automatic gain control MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 2 Jan 1973 281/73 Heading H3T In a television receiver using a synchronous detector from the output of which an automatic gain control circuit is fed, the detector is preceded by a limiter (Fig. 3, not shown). The limiter prevents the sudden application -of an excessive signal to the detector, the output of which falls below a maximum allowable input level. The limiter may comprise series capacitors 11, 12, Fig. 5 in the signal path, together with shunt diode 7 and a source of bias 8; alternatively two oppositely-connected diodes in parallel may be used (Fig. 6, not shown). In the automatic gain control circuit, rectified video signal is applied to the base of transistor 20, Fig. 7 the emitter of which is commoned with those of transistors 18, 19 arid connected by way of a current source comprising the collector to emitter path of a further transistor to earth. Line pulses are applied to the base of a gate transistor 18 and a delay bias to the base of transistor 19. Pulses in the collector circuit of transistor 19 depending upon the value of the sync. pulses are rectified by diode 21 and smoothed by circuit 22, 23; the smoothed voltage is passed by emitter-follower 24 to a further R.C. circuit 30, 31 from which the video I.F. gain control is derived. A further delayed gain control signal is obtained at terminal 28 by means of transistors 26, 27. Synchronous detector.-Video I.F. signal applied to terminal 32, Fig. 11 is amplified by transistors 33, 34 and clipped by diodes 35, 36 to produce a residual carrier wave. Video I.F. signal is also amplified by transistors 37, 38 and the carrier and video I.F. signal mixed and detected by transistors 39, 40.
