Title: Improvements in or relating to electric current regulators
IPC: G05F1/648
Filed: 1933-10-30
Abstract: 427,430. Automatic regulation. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WESTELL, E. P. L., c/o General Electric Co., Coventry. Oct. 30, 1933, No. 30090. [Class 38 (iv)] In apparatus in which resistances controlled by a chain of relays are employed to obtain constant current from a supply of varying voltage, the operation of one relay sets the next relay in the chain ready for operation, the relays being operated in one direction by connecting them to a source of voltage and in the other by short circuiting them. Resistances RA-RK are put into or cut out of the circuit in succession by switches A4-K4 operated by relays A-K. The relays are controlled by a moving finger 1 which engages fixed contacts 3 or 4 according to whether the current flowing in the coil 2 is above or below a predetermined value. As long as finger 1 engages contact 3, the relays all brought into action rapidly in succession, the action only ceasing when all the resistances are switched in or when the finger 1 leaves contact 3. When for example relay A is operated, the resistance controlling switch A4 is opened, switch A3, which maintains the relay in operation, is closed, and switch A2 is closed and thereby closes the circuit of relay B which is thereupon operated. Relay B similarly operates switches B4, B3, B2 and also opens switch B1. When finger 1 engages contact 4, those of the switches K1-B1 which are still closed short circuit the relays in succession and cut them out of action. Specifications 27618/02, [Class 38], 6567/09, [Class 38 (iii)], and 12427/10, [Class 38 (iv)], are referred to.

Filed: 1974-07-08
Abstract: 1421690 Load responsive valve arrangement; valves SVENSKA AB BROMSREGULATOR 8 July 1974 [11 July 1973] 30108/74 Headings F2F and F2V A load responsive valve arrangement controls pressure fluid flow to a servomotor of a vehicle brake system to give a lower or higher braking effort according to whether the vehicle load is below or above a particular value; the valve arrangement comprises a two-part housing 1, 2 mounted on aprt of the vehicle underframe and a flexible spring steel control arm 7 actuated by another underframe part, the two parts being movable relative to each other when the load changes. The control arm 7 connects with a control shaft 5 journalled in the housing 1, 2 and as vehicle load increases the arm 7 rotates shaft 5 clockwise; secured to a control yoke 9 integral with the shaft 5 is a control pin 10 whose movement allows control of an insert valve 15, 15A to control communication between ports 13, 14, the port 13 being connected to a source of fluid pressure and the port 14 being connected to the servomotor. In this embodiment the fluid is compressed air but it may be hydraulic or vacuum. A return spring 11 urges the control pin 10 against an abutment 1A and acts to turn the control shaft 5 anti-clockwise when there is a decrease in vehicle load. A tubular spring support 12 limits compression of spring 11 and movement of pin 10 by the shaft 5; if the vehicle load increases after support 11 engages housing part 2, the arm 7 flexes. A movable projection 15A of the insert valve is operable by a control stem 16 which has a flange 16B urged against the control pin 10 by a helical compression valve-operating spring 18 which is weaker than the return spring 11. The control stem 16 has a venting passage 16A which vents port 14 to atmosphere in the position of the control stem 16 is shown in which the insert valve is closed and port 13 is disconnected from port 14. If the vehicle load increases above the particular value the control pin 10 is moved upwards, and the control stem 16 is moved upwards by spring 18 to close passage 16A and to open valve 15, 15A and connect ports 13, 14. The arrangement prevents great forces being transmitted to valve 15, 15A since it is the spring 18 solely which operates the valve. When the vehicle load decreases below the particular value the spring 11 urges yoke 9, pin 10 and flange 16B to move to their illustrated position. In an hydraulic arrangement passage 16A communicates with a reservoir.

Filed: 1950-12-13
Abstract: <PICT:0699641/III/1> <PICT:0699641/III/2> <PICT:0699641/III/3> A gas analyser for continuously determining the content of a paramagnetic gas in a mixture is provided with an elongated temperature sensitive resistor disposed lengthwise in a horizontal tubular gas cell, the axis of the resistor being displaced from the plane defined by the lines of maximum intensity of a magnetic field between pole pieces disposed lengthwise on opposite sides of the cell.  The magnetic convection currents assist or oppose the thermal convection currents thus cooling or heating the resistor, the change in temperature of which is proportional to the paramagnetic gas content of the mixture in the cell.  In Figs. 1 and 3 identical resistors 16 and 17 are placed in gas cells 14 and 15, the latter being for comparison purposes, on either side of a supply pipe 12.  The cell 14 is subjected to an offset magnetic field from magnet 22 with pole pieces 23 (Fig. 3) which set up magnetic convection currents (full lines) to assist thermal convection currents (dotted lines) thus cooling the resistor 16 which with resistor 17 form adjacent arms of a Wheatstone bridge circuit.  The unbalance of the bridge consequent upon the cooling and hence decrease in resistance of resistor 16 is proportional to the paramagnetic gas content.  Alternatively, as shown in Fig. 7, the magnetic field is applied to both cells, preferably on the same side of the supply pipe, the magnetic convection currents opposing in one and assisting in the other the thermal connection currents, the resistors as before being incorporated in a Wheatstone bridge.  Either of the above types of circuits may be used in conjunction with the other the cells in one circuit being filled with a standard gas.  The ratio of the unbalance of the two bridges is then measured.  Slack diaphragms are provided in the cells containing the standard gas, if other than air, assuming the test cells are worked under atmospheric pressure.  In a further modification a single gas cell is provided, the resistor of which forms one arm of a Wheatstone bridge, which is operated isothermally, the unbalance of the bridge being corrected by increasing manually or automatically, the current input to the bridge to restore the temperature of the resistor.  An ammeter, voltmeter or wattmeter measuring the current, voltage drop or :  input is calibrated to read directly in terms of the paramagnetic gas content.  Preferably such a bridge containing instead a cell containing a standard gas is connected, preferably in parallel to a second bridge circuit otherwise similar containing the analysis cell, the first bridge controlling the input to the second.  The unbalance of the second cell is measured as before.  It is preferable in this case to connect the two four-armed bridges to a six-arm bridge supplied with current from a common source.  The isothermal operation of the first circuit, containing the standard gas may also be effected by a separate heater circuit controlled by the unbalance of the first circuit.
