Abstract: 393,717. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fredericks, J. de M. ; 151, Delmar Place, Irvington, New Jersey, U.S.A.) March 16, 1932, No. 7841. Convention date, March 16, 1931. [Class 38 (iii).] Travelling to predetermined limits.-In a dish-washing machine automatic valve-actuating mechanism is provided for effecting a timed sequence of operations, including a starting cycle, a washing and rinsing cycle, and a finishing cycle, and a manually-operable control is provided for initiating and stopping each cycle of operation. In the construction shown, the valves are actuated by the step-by-step movement of a shaft 103 effected by the energization of an electromagnet 105. The circuit of the electromagnet, deriving its current from an alternating current source 62b, includes a control switch 132 normally held in a neutral position by spring 134a. The switch is closed by the engagement of the switch member 132b by one or other of two cams 135, 136 adapted to be rotated, respectively, by constant-speed electric motors 140,141. The energization of these motors is controlled by means of a manually-operable lever 153 normally held by springs 157 in a neutral position. Movement of the lever about its pivot 154 in a clockwise direction closes contacts 155 to complete a circuit for the motor 141, reverse movement causing the energization of motor 141. The lever is connected by a rod 183 and a crank arm 182 to a lever 176 provided at one end with a pin 177 adapted to enter either of two diametricallyopposite holes 178, 179 in the cam 135, and at the other end with a pin 180 adapted to enter a hole 181 in the cam 136. To operate the machine, the handle of the lever 153 is moved to close contacts 155 and start the motor 140. The cam 135 turns through half a revolution and is then stopped by the pin 177 entering the hole 179, while the circuit of the motor 140 is opened by the lever 153. This lever is then moved manually to close contacts 156 and start the motor 141 which drives the cam 136 through a complete revolution, the cam being stopped bv the pin 180 entering the .hole 181 and permitting the lever 153 to open the circuit of the motor 141. The lever 153 is again operated to start the motor 140 which causes the cam 135 to complete the second half of its revolution, whereupon the motor 140 is stopped and the complete cycle of operation of the machine is finished.

Title: Automatic adjuster for vehicle brakes
Inventor: TOMPKIN JOHN BARRYMORE
IPC: F16D55/224
Filed: 1958-03-12
Abstract: 843,230. Disc brake adjustment. GIRLING Ltd. March 11, 1959 [March 12, 1958], No. 7905/58. Class 103 (1). In an automatic adjuster for power-operated disc brakes for railway vehicles of the kind in which friction pads 31 adapted to be applied to opposite faces of a rotating disc 30 are mounted on the inner ends of interconnected caliper levers 33, 34 of which one (33) is pivoted at its outer end to the piston or diaphragm of a fluid-pressure cylinder 38 (e.g. vacuum), the pivot 39 for the non-actuated caliper lever 34 is carried or located by a piston-rod 40 associated with a piston 41 working in a cylinder 42 into which liquid is forced through a non- return valve 45 by a sensing piston 48 working in another cylinder 47 and coupled through a lost-motion device 53, 50 to the piston-rod or like of the fluid-pressure cylinder 38. In operation, should the stroke of the fluid pressure actuator exceed a predetermined value, as determined by the free movement of fork 53 between shoulder 54 and abutment 51, through wear of the friction pads or other parts of the brake mechanism, the sensing piston 48 forces liquid into the first cylinder 42 via non-return valve 45 and moves piston 41 outwardly so that the pivot of the non-actuated caliper lever 34 is displaced through a distance sufficient to compensate for the wear and to restore the stroke of the power actuator to its normal value. A diagrammatic representation is illustrated in Fig. 1 wherein when fork or collar 18 attached to the piston-rod of a fluid pressure actuator engages the outer shoulder 19 of reduced diameter part 17 of sensing piston 16 the latter piston is moved outwardly through a small distance dependent on the amount of wear of the friction pads. This outward movement of piston 16 causes liquid to be drawn into the inner end of the bore 12 through valve 21 from reservoir 10. On release of the brake, the collar 18 on its return movement engages the shoulder 20 and moves piston 16 inwardly so that surplus liquid which has been drawn into the bore 12 is forced through a valve 22 into the inner end of a bore 11 and moves a piston 13 outwardly to engage the non-actuated or anchored caliper lever of the disc brake. When the friction pads are worn and have to be replaced, opening of a valve 23 allows liquid to return from the bore 11 to the reservoir to restore the parts to their original positions.

Filed: 1943-05-19
Abstract: 572,514. Hydraulic transmission of power. THOMAS, A. N. May 19, 1943, No. 7951. [Class 69 (ii)] The speed of a driven shaft is maintained at a constant value by a hydraulic transmission comprising a pump operated by the driving shaft and delivering liquid to a control means on the driven shaft responsive to centrifugal force and regulating the flow through the pump. A clutch 12 between a driving source and compressor comprises a casing 23 belt driven from the main shaft and carrying planet pinions 43 engaging a sun-wheel 42 in the driven shaft and co-operating therewith to pump liquid from the casing 12 into a chamber 58. The latter is connected to the driven shaft and carries radial chambers 63 having ports 69 controlled by spring-loaded valves 66. When the speed of the driven shaft reaches a predetermined value, the valves 65 move radially under centrifugal force to open the ports 69 and the pump discharges into the casing. The spring 65 may be manually or automatically adjustable to obtain any desired constant speed of the driven shaft.

Title: Coupling a two-way path to two one-way paths in electric signalling systems and devices therefor
IPC: H04B1/58
Filed: 1931-03-16
Abstract: 374,528. Two-way transmission. STANDARD TELEPHONES & CABLES, Ltd., LATIMER, K. E., and RENDALL, A. R. A., Connaught House, Aldwych, London. March 16, 1931, No. 8036. [Class 40 (iv).] A hybrid coil for connection to a two-way line without the interposition of repeating coils, and having the windings of the twoway line, two one-way lines and balancing network insulated from each other, is so arranged that currents flowing through the conductors of the two-way line in parallel (phantom circuit, simplex telegraph or interference currents) and passing through the phantom tap to other circuits or through the self capacity of the windings to earth, do not give rise to currents in the one-way paths. The output and input windings in the one-way paths may be connected directly in the grid or anode circuits of the amplifying valves. Arrangements are also described for varying the ratio of the windings and for using the same coil on lines of different impedances, and for connecting the coil to the one-way paths over a second hybrid coil. In the arrangement shown in Fig. 2, the line windings are subdivided and cross-connected to obtain the desired result. To provide against interference only, the capacity to earth or other point of the line windings is concentrated at the points of connection of the windings to the two-way line. This may be done, as shown in Fig. 6, by enclosing the line windings in a live shield and interposing shields, preferably earthed, between the live shields and the one-way windings ; or a one-way path winding and the corresponding network winding are wound first on a spool followed by an earthed screen and then the corresponding line winding the inner end of which is connected to line, the other windings being similarly arranged on a second spool. In the modification shown in Fig. 4, a coil H with cross-connected windings as in Fig. 2 is provided with modified input and output windings connected to the one-way paths R1, R2 by a second hybrid coil W4, W5, W6. The impedance of the lines may be equalized over jacks J used also for measuring. The arrangement shown in Fig. 5 using a coil in which the line to network ratio is not unity may be applied to the arrangements previously described. This arrangement may be used to work on lines of two different suitable impedances by interchanging the line and network connections, and the gain may be measured by an instrument having only one of these impedances. Tappings may be used to connect to lines of other impedances and to obtain gain measurements. As shown, the hybrid coil may be arranged to work with line of impedance 2R, R, or ¢R (tapping) but when the cross-connection method, Fig. 2, is used, an additional winding is preferable to the tap.

Abstract: 213,621. Demole, E., and M³ller, M. March 31, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches partly electromagnetic and thermal; contacts.-In order to prevent sparking between the contacts of a. thermostat controlling the temperature of an electrically-heated oven or similar apparatus by ensuring their rapid approach or separation when the heating-circuit is being established or broken, the contacts 3, 6 are arranged to be separated under the action of the thermostat 8 against the force of attraction between an electromagnet 5 and its armature 1, which is magnetized either permanently or by means of an electromagnetic field, the magnetic force decreasing rapidly when the contacts are only slightly separated owing to the interposition of an air gap in the magnetic circuit. In the construction shown, a bimetallic strip thermostat is employed operating in conjunction with a rod 7 and an adjustable abutting screw 2 on the armature 1, but a capsule or other form of thermostat may be employed. The contact 6 is mounted directly on the magnet 5, while the armature 1 is hinged to the magnet at the point 4.
