Title: Automatic adjusters for vehicle brakes
IPC: F16D65/54
Filed: 1974-03-20
Abstract: 1501093 Brake wear adjusting GIRLING Ltd 10 March 1975 [20 March 1974] 12244/74 Addition to 1152712 Heading F2E In an hydraulic brake actuator of the type in which a wear adjusting ratchet mechanism operates between the piston 1 and a mechanical actuator mounted in a counter-member of the hydraulic actuator (e.g. a further piston or, as shown, the cylinder 2) the mechanical actuator rotates about an axis parallel to that of the cylinder. Rotation of a handbrake lever 10 secured to a shaft 7 having a head 8 causes a thrust member 13, which threadedly engages head 8 and is prevented from rotating by projection 24, to move axially. Surface 16 of member 13 abuts complementary surfaces 17 on pawls 21 and forces them into engagement with linear ratchet teeth 19 on a rod 15 attached to the piston; the piston is thus advanced, without wear adjustment, and slippage of the ratchet mechanism is prevented. Pawls 21 are formed as spring-fingers on a ring 14 slidable on rod 15, movement of the ring to the left being limited by washer 26 fixed to thrust member 13. If therefore on hydraulic actuation the movement of piston 1, and hence rod 13, is excessive the pawls slip a tooth to increase the effective length of the strut formed by the ratchet mechanism.

Abstract: 929,907. Automatic aircraft control. BENDIX CORPORATION. April 6, 1961 [April 7, 1960], No. 12422/61. Class 38 (4). [Also in Groups XXIV and XXXIII] An actuator mechanism for adjustably positioning a control surface on an aircraft includes actuator means driven by a two-stage gear train from which a dual output speed is obtainable through electromagnetic means so arranged as to couple selectively an actuator motor to the first or to the second stage of said gear train so as to drive said actuator means at relatively high or low speed ratio respectively and operatoroperative means for controlling the electromagnetic means so as to effect selectively the foregoing operation. A two-speed trim actuator mechanism 3 comprises a screw jack 91 connected at 92 to operate a trim surface 93. A manually operated control column 112 has a trim button 115 to actuate a switch 117 to open a circuit from a battery 119, conductors 123, 128, limit switch 103 in the actuator, conductor 129 relay winding 131 of a gang relay 132 and a conductor 133 to a solenoid 11. The solenoid actuates a clutch in the actuator so that one part or all of a two-part planetary gear train (see Group XXIV) is drivingly connected to an electric motor 13. An autopilot 110 is connected by a shaft 150 to the rotor 149 of a synchro 143, the stator 141 being connected through switches 135, 137 and 139 of relay 132 to a corresponding stator 145 of a synchro 147, of which the rotor 151 is connected by a shaft 153 to surface 93 to provide a feedback output over conductors 155 and amplifier 158 to motor 13. Limit switch 103 is provided to ensure that the autopilot does not over-trim. In operation, button 15 is normally biased by a spring 127 to hold switch 117 closed whereby solenoid 11 actuates the clutch in the actuator so that the jack is driven at a relatively low speed in response to movements of rotor 149 controlled by autopilot 110, the energization of solenoid 131 moving switch elements 135- 137 to the left against action of spring 63. Actuation by the pilot of button 15 opens switch 117 and switches 135-139 so that movement of lever 112 displaces rotor 171 of synchro 167 to cause the jack to move at a relatively high speed. A manually operated flexible driveshaft connection (not shown) is provided between the cockpit and the gear train in the actuator. Specification 801,941 is referred to.

Title: Means for producing a constant electric current capable of adjustment
IPC: G05F1/32
Filed: 1936-05-08
Abstract: 479,596. Automatic regulation. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 8, 1936, No. 13049. Convention date, May 17, 1935. [Class 38 (iv)] An adjustable constant alternating current is obtained from a variable voltage A.C. source by a series connected D.C. biassed inductance the current through which is combined with current through a fixed choke or condenser having a value corresponding to the slope of the voltage x current curve of the biassed choke at its inflection point. A choke 6 in series with the load 11 is adjustably biassed by a D.C.. winding 5 supplied through a rectifier 4 and constant current transformer 2, 3 from the A.C. source whereby the choke is provided with a constant but adjustable D.C. bias. The slope of the A.C. voltage current curve of the choke 6, over its straight part, is compensated by a parallel connected condenser 7 having a corresponding reactance so that the resultant characteristic is vertical over this part and the load current is maintained constant within certain limits of voltage variation of the supply or load. Alternatively the slope of the choke characteristic may be compensated, Fig. 3, by reversely combining current through it with current through a constant inductance 15 supplied from the mains. This is done in a transformer of which windings 16 and 17 are in series with chokes 6 and 15 respectively and oppose one another, and winding 18 supplies the load 11 with constant current. The biassing winding 5 is supplied with adjustable constant current from a D.C. source through a barretter 14 and potentiometer 1 whereby the value of the constant A.C. is adjusted. The Specification as open to inspection under Sect. 91 stated that the slope of the characteristic of the choke may be so steep as to render compensating means unnecessary. An arrangement was also disclosed in which the current through the biassing winding was varied in accordance with the voltage across the choke 6 so that a resultant characteristic having a vertical part was obtained. This was attained by arranging the constant current saturated and unsaturated transformers 2, 3 so that their characteristics converged slightly and connecting them across the choke 6 so that the current through the biassing winding 5 decreased as the voltage across the choke increased. This subjectmatter does not appear in the Specification as accepted.
