Patent GB-819776-A (GB)
Title: Improvements in apparatus for controlling the unloading of a spring
IPC: B60G17/027
Filed: 1957-10-17
Abstract: 819,776. Vehicle spring suspensions; hydraulic shock absorbers. EDWARDS, R. W. Oct. 17, 1957, No. 32406/57. Classes 108(2) and 108(3) An apparatus for controlling the unloading of a helical suspension spring 10, Fig. 1, disposed between a vehicle chassis 11 and a lower link 12 of an independent suspension comprises a lever 32 pivoted to the link, one arm of the lever being connected to the helical spring 10 to apply loading force from the link in opposition to the force applied by the chassis, a second spring 35 connected between the link and the other lever arm so as to be loaded when the helical spring is loaded, and a hydraulic damper 25 controlled by movement of the lever 32, which holds the helical spring in its loaded state and releases it when the second spring 35 is unloaded so that rebound of the suspension spring occurs relatively slowly and does not impart shocks to the vehicle chassis. In operation when a wheel strikes a bump, spindle 14, Fig. 1, post 15 and links 12, 17 move upwards. Upward movement of link 12 acts through lever 32, pivoted to link 12 at 33, against eye 28 of hydraulic damper 25, to compress spring 10 between seat 22 on chassis 11 and seat 23 pinned to eye 28. Compression of spring 10 causes lever 34 to pivot and compress spring 35, and through links 49, 48, Fig. 5, 47, 46 to move sleeve 44 downwards along cylinder 38 to close ports 42 so that hydraulic fluid above piston 39 is trapped. Thus piston 39 cannot. move upwards and spring 10 is locked in loaded condition and cannot suddenly rebound. Spring 35, Fig. 1, now expands and lifts chassis 11 relative to link 12 through the arms of lever 32. Pivoting of lever 32 now moves slide 44 upwards through links 49, 48, Fig. 5, 47 and 46 to align ports 45 with ports 42 so that hydraulic fluid trapped above piston 39 may escape. This permits piston 39 to rise slowly in cylinder 38 and spring 10 to expand slowly. Any tendency for spring 10 to expand suddenly is checked by movement of lever 32 which closes ports 42 and holds piston 39 stationary. To augment the strength of spring 35 when leaning of the vehicle causes weight to be thrown towards the wheel spindle, pendulum 80, Fig. 2, mounted on rod 81 under link 12 swings outwards so that end 84, Figs. 2, 1, of rod 81 bears down on arm 34 of lever 32 near spring 35. Spring 35 may be placed inside a telescopic capsule 70, Fig. 4, movable along arm 34 of lever 32 so that the leverage exerted by the spring may be varied to suit different load conditions, preferably by a flexible control wire 75 from the vehicle cab.

Title: Improvements in or relating to electric fuses or cut-outs
IPC: H01H85/38
Filed: 1946-11-01
Abstract: 619,239. Cut-outs. MULLER, H. Nov. 1, 1946, No. 32445. [Class 38 (i)] A fuse comprises a mass of iron B in proximity to a fusible wire A which is stretched over two sharp-edged members F, G. A large current in the wire A magnetizes the iron B which attracts the wire and facilitates its rupture. The wire may be supported by several members similar to the members F, G arranged at intervals along the insulating base C. Fig. 4 shows a modification in which the wire passes round two sides and one end of the base which is provided with an iron mass B between the two side portions of the wire and a sharp projection H at one end. The wire may completely encircle the base which is then provided with a projection at each end. The iron B may be replaced by a permanent magnet which projects at right angles from the base. The wire is attracted towards the magnet for only one direction of the current. Fig. 7 shows a further modification in which a permanent magnet B is placed in the same position as the iron in Fig. 1. The wire in this construction passes through an opening in a mica bridgepiece H which produces a shearing force on the wire when a large current passes. Instead of a single piece of iron several pieces may be arranged on opposite sides of the wire alternately, the wire passing through apertures in a number of bridge-pieces. Fig. 10 shows two iron masses B, B1, on opposite sides of a wire A which passes through an opening in a bridgepiece F. The opening has sharp edges K, L. A three-phase circuit may be provided with a fuse comprising three wires on one side of an iron mass or two wires on one side and one on the other, all the wires passing over sharp rupturing edges.

Title: Improvements in or relating to electric control apparatus
IPC: B60L15/12
Filed: 1923-12-29
Abstract: 230,207. Poolman, C. G. N. Dec. 29, 1923. Master control sys - tems; systems controlling travel for a fixed distance; series-parallel systems.- In controlling a motor to follow the movements of a master handle, a polarized relav connected between tworanges of contacts with variable resistances in the manner of a Wheatstone bridge determines the starting and stopping of the motor at the required points. The range of contacts on the following side comprises alternate extra contacts at intermediate potentials. If the master handle is. moved backwards at any point, the relay is independently energized so as to run the motor back either to its starting point, or to a position corresponding to the backward setting of the master controller, after which the follow up action can be resumed. Tappings from battery cells or other sources of graduated potential may replace the resistances. A number of motors controlled in the above manner may be used to operate the main controllers in a multiple-unit traction system. Fig. 1 shows an arrangement according to the invention for controlling one unit of such a system. The controller-operating motor 24 is started and stopped by a reversing switch 25 subject to a polarized relay 16 connected between two tapped resistances 13, 14 which are connected across an auxiliary generator 12. A master controller 15 in moving from zero position first completes the connection through the relay 16 and afterwards controls the tappings of the resistance 13, the resultant unbalanced current energizing the relay and starting the motor 24 which actuates a slider 18 over tap-contacts of the resistance 14 until the balance is restored. The tap-contacts are alternately long and short, the rest positions being on the short contacts only. The rate of progression is under the control of a current-limit relay 9. Anybackward movement of the master controller takes immediate effect upon a loose segment 27 which brings about the opening of a main circuit switch, the de-energization of the relay 16, and the reverse energization of the motor 24 through a switch 29 operated by the slider 18. In a series-parallel system employing two motors 20, 21, one of which may be cut-out by a switch 45, the operation of the cut-out switch leaves the circuit of the relay 16 in a condition which causes the slider to stop on an intermediate contact, owing to the separation of contacts 47, 48 by a. tappet 52, Fig. 3. Modified arrangements in which the running back of the motor 24 corresponds to the backward setting of the master controller and in which the power circuit connections are simplified, are described in detail.

Filed: 1936-11-27
Abstract: 486,020. Electron multipliers and circuits therefor. STANDARD TELEPHONES & CABLES, Ltd. Nov. 27, 1936, No. 32556. Convention date, Dec. 28, 1395. [Classes 39 (i) and 40 (v)] An arrangement in which relatively out-of-phase potentials are applied to the electrodes from one or more oscillation sources is provided for continuously varying the strength, or direction, or both of the fields between secondary-emitting electrodes so that electrons emitted by each electrode are displaced towards the next electrode. Sinusoidal, pulsating rectified, or rectangular or saw-toothed voltages with phase displacements may be applied to successive multiplying electrodes or successive intermediate grids, so that the electrodes become positive in turn and attract all the electrons emitted from the preceding stages. The multiplier may comprise a caesiated mica cathode Ph, Fig. 8, an output electrode A, and multiplying grids 1, 2, 3, 4, 1<1>, 2<1>, 3<1>, 4<1>, connected in sequence to leads 6. Glass rods 5 support the structure. In a modification the multiplying electrodes are flat or curved plates arranged in helical fashion, and a magnet may be arranged axially. Each plate may be impacted twice. In the form shown in Fig. 11B, the main electrodes C, 1, 2, A are at fixed potentials and varying potentials are applied to the biassed grids g<1>, g<1>1, g<2> g<1>2, g<3>, g<1>3 ; screen or suppression grids may be provided. The multiplying electrodes may be successive frusta of a cone and may be water-cooled. The amplification may be varied by altering the number of stages, or by varying the biasses on the multiplying electrodes or on the field-producing grids. Two tubes may be connected in series by connecting the output electrode of one tube to the grid of the next. The varying potentials may be supplied from a common oscillator through phase-shift networks, or the oscillator may be replaced by an output filter selecting the output carrier frequency so that the tube is self-excited. The filtered output is then stabilized or modified as desired, e.g. to stabilize the non-carrier output. Positive or negative feed-back may be used in an amplifier circuit. The device may be used as an oscillator or modulator.
