Title: Improvements in or relating to railway signalling apparatus
IPC: B61L3/02
Filed: 1931-03-31
Abstract: 372,506. Actuating signals on trains. BALLS, S. T., 34, Cowcross Street, London. March 31, 1931, No. 9706. [Class 105.] Relates to track apparatus for actuating signals and brakes on trains, of the type comprising a fixed track ramp engaged by a pivoted lever on the locomotive to give a clear signal (bell) or a danger signal (siren) with brake application accordingly as the ramp is electrically alive or dead in dependence on the position of the wayside signal. The pivoted lever 1 is formed with an angular shoe 1<B> so that a face thereof engages the ramp surface and is held thereto by the action of a spring 4. Throughout the angular movement of the lever 1 the ramp is connected through the shoe 1<B>, a stud 8 sliding over an arcuate strip 6, and a lead 7, with the electromagnetic control apparatus. A similar stud contact device on the lever may be provided with an insulated stud moving over two short arcuate strips to act as a switch which is opened on movement of the lever by the ramp; this switch is diagrammatically denoted by 5<A> in Fig. 8, which shows one form of the control apparatus. At a clear signal the ramp is electrically alive so that a magnet 15 is energized over the lead 7 during the passage of the locomotive lever 1 over the ramp; the normal circuit of a magnet 26 is broken at the switch 5<A> by the deflection of the locomotive lever 1 but this magnet 26 continues energized over contacts 21, 22 closed by the lifted armature device 17 of magnet 15 which further closes a contact 23 in the circuit to a bell 25. A battery 24 supplies the magnet 26 and bell 25. The armature contact device 17 is held in. its lifted position by a spring. 47 until manually released. At a danger signal the ramp is dead and accordingly the magnet 15 is not energized to complete the parallel holding circuit for magnet 26 which therefore drops its armature device 28; when the switch 5<A> opens, and so actuates the brake valve 35, the air operating a siren 37. The modified form of lever 1, shown in Fig. 7, when deflected allows a rod 11 to drop and therefore in the apparatus shown in Fig. 9 the armature device 28 of magnet 26, being supported by the rod 11, will drop unless the ramp is alive to energize the magnet 26 directly over the lead 7. If the magnet 26 is so energized its armature device 28 closes contacts 32, 33 to energize the magnet 15 which in turn lifts its armature. device 17 to close the circuit to the bell 25. By means of the apparatus shown in Fig. 12 the brake application when initiated is prevented from being cancelled. The brake valve lever 34<A> when operated passes beneath a spring catch 54<A> which is only withdrawn when the fall of air pressure in the piping 36 permits a spring- pressed piston 49 to descend and actuate the linkage 53, 59.

Abstract: 551,661. Actuation of switches ; switches held set and freed mechanically. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and BALFOUR, J. W. A. Aug 1, 1941, No. 9829. [Class 38 (v)] A control panel bearing a diagram of signals, points &c. has keys mounted near the positions indicated on the diagram of the apparatus controlled, each operating a switch carried on a distant support through a mechanical connection, one at least of the switches comprising a plurality of contacts ganged together. In the example, switch contacts 26 are carried on supports 23 at a distance from a panel upon which a switch operating arm 15 is mounted, moving contacts 33, 33A, 33B carried on a sliding rod 28 being operated by a mechanical connection shown as a wire 20 in a rigid outer tube 22 but which may be hydraulic or pneumatic. In the example, springs 34 tend to return the sliding rod to a central position and the moving contacts bridge appropriate tongues 26 in the three positions obtained by the movement of the wire 20, in response to movement of arm 15, through the lever 18. In a modification the bridging contacts are supported on a rod capable of being rotated to take up three positions by movement of the wire 20, to effect the required switching arrangement. In a further modification any one of several such switches can be operated selectively by arranging the wires 20 with their casings 22 as a circular mount 80, each having a tappet 78, Fig. 7, at the operating end. A sleeve 70 bearing a knob 72 at the end and a pivoted arm 75 at the other is turned until the desired switch tappet is over the arm 75. On depressing a knob 84, a sliding member 77 actuates the arm 75 to pull the tappet 78 to operate the switch. A pin 87 can be caused, by turning the knob 84, to be retained in a notch to keep the tappet in pulled position. Specification 515,793, [Group XXX], is referred to.

Filed: 1989-08-02
Abstract: A control arrangement for a home entertainment unit, including a television receiver and one or more peripheral devices, such as a video recorder, coupled to the television receiver, includes a single remote control transmitter for transmitting a remote control signal to the television receiver, which, in turn, passes on control instructions to the peripheral devices. To allow such a remote control operation, even when one or more of the peripheral devices is produced by a manufacturer different than that of the television receiver and which therefore requires a different remote control code, the television receiver has a memory in which, under the control of a microprocessor, the remote control codes allocated to respective function control keys of the remote control transmitter supplied with a peripheral device are stored during a learning process. During the learning process, the screen of the television receiver displays messages for instructing the user which function control key of the remote control transmitter associated with the peripheral device to press. Thereafter, when a device function control key of the remote control transmitter supplied with the television receiver is pressed, the microprocessor, working in conjunction with the memory, converts or translates the codes contained within the received remote control messages to codes corresponding to the peripheral device and a correspondingly encoded remote control signal is relayed by the television receiver to the peripheral device.

IPC: H02M1/08
Filed: 1981-01-09
Abstract: PURPOSE:To prevent the rush current to an induction load by gradually raising an output voltage by controlling the ON operating phase of an AC switch after a throw instruction for closing the switch is produced. CONSTITUTION:A gate pulse is fed to a thyristor 121 at a point a upon production of the ON command of an AC switch 12. The contact B of a changeover switch 303 is closed under the conditions that the output voltage of the switch 12 is zero and the switch 12 is first thrown. When the ON command is fed in this state, the ON command is inputted through the contact B to an integrating circuit 304. The output from the circuit 304 is fed to a gate pulse generator 305, which in turn produces a gate pulse controlled in phase at the time b. Thus, it can prevent the rush current to an induction load such as a transformer or the like.
