Title: Electric multiple-contact relay the contacts of which are progressively closed
IPC: H02P9/18
Filed: 1950-05-18
Abstract: 674,688. Electromagnetic switches; regulating switches. ECLAIRAGE DES VEHICULES SUR RAIL. May 18, 1950. [May 24, 1949] No. 12472/50. Class 38 (v). [Also in Group XXXV] Variation of voltage at 9 causes a coil 2 to move a member 3 so as to cause the successive engagement of contacts 6 connected to points on a resistance 7 and of intermediate contacts connected to circuits 8. Thus a particular voltage at 9 causes a particular number of circuits 8 to be closed. The circuits 8 may lead to contactors controlling resistances, inductances, capacitances, etc., so that the resistance, say, controlled by them is a function of the voltage 9. The resistances between the contacts 6 need not be equal and the above function may be anything desired, e.g. a logarithmic function. In a modification, Fig. 2 (not shown), the above relay is associated with a vibrating regulator which, by short circuiting a resistance in series with the coil 2 serves to amplify the effect of the variation of voltage. In another modification, Fig. 3, a constant source of voltage 16 is applied to the relay and the variable voltage 15 is applied to a coil 13 of the vibratory regulator 10. For each value of voltage 15 there will correspond a definite position of the control member 3 of the relay. In a further modification, Fig. 4 (not shown), the variable voltage 15 is applied to a coil on the same core as the coil 2 of the relay.

Filed: 1974-04-30
Abstract: 1472862 Bar-stock feeding WICKMAN MACHINE TOOL SALES Ltd 30 April 1974 [15 March 1973] 12544/73 Heading B3B A bar feed control device mounted on a multispindle lathe comprises an arm 15 fixed to a shaft 14 which can be rotated to angularly swing the arm 15 and moved axially to laterally move the arm, the arm including a stop surface 17 and a projecting finger 16. In a method of controlling the bar feed, the shaft 14 is moved axially to move the arm 15 away from a spindle 12 and also rotated to swing the arm 15 into alignment with the said spindle so that a bar fed through the spindle chuck to engage the stop surface 17 protrudes more than is required. The arm is moved further angularly so that finger 16 knocks the bar so that if only a short section of the bar is remaining it will be knocked from the spindle chuck. If a long section of bar is remaining a lost motion drive in the rotation of the shaft 14 allows the arm 15 to bear against the bar. The shaft 14 is then retracted axially to move the bar back into the spindle chuck to a required machining position, and then rotated to swing the arm to a clear position.

Title: Motion control system for an inductively controlled multi-phase motor
IPC: G05B19/23
Filed: 1975-03-27
Abstract: 1516645 Automatic control TEXAS INSTRUMENTS Inc 27 March 1975 [1 April 1974] 12891/75 Heading G3N A motor control system for e.g. a printhead employs a multi-phase motor 75 operable in stepping or continuous mode to whose coils 72-4 suitable driving currents are connected to drive the motor in one or the other direction, and to retard it by energizing one or more lagging phases when approaching a desired position. Sensors 76, 77 indicate motor position for synchronization of energizing or braking currents. "Print", "carriage return" and "back space" modes may be selected via flip flops 17 and ROM 22 which provides sequential coded outputs Y5-Y7 indicating the motor phases to be energized. In the print mode for example, rotation is initiated by selecting a suitable phase, then tachometer 76 detects rotation and signals trigger and timing circuit 80, this in turn selects a lagging phase to brake the motor and reselects the motion phase which now holds the motor stationary at the desired position. Printing is effected and flip flop 17 and ROM 22 step on to the next motion phase to rotate the motor again. Excess or low speed of the head over the paper is compensated by detecting it in drive circuit 30 Fig. 3 (not shown) and applying more or less braking current. Backspace is achieved in a similar manner but without an allowance for the time taken to print, and carriage return is by continuous operation of the motor until nearly home and then braking with two lagging phases to bring the head smoothly back.

Title: Improvements in ignition-timing and like couplings
IPC: F02P5/06
Filed: 1946-04-30
Abstract: 613,546. Automatically-adjustable couplings. BENDIX AVIATION CORPORATION. April 30, 1946, No. 13013. Convention date, May 7, 1945. [Class 80 (ii)] [Also in Group XXVII] In an ignition timing or like coupling a driving member 11, which has external splines 19 for engagement with the engine; is journalled upon a sleeve 28 that surrounds a shaft 10, the other end of the latter being splined to receive a driven member 12. To provide for relative angular displacement of the driving and driven members 11, 12, their inner ends engage with two pairs of gear segments 15, 16, one of each of which are pivoted upon diametricallyopposed pins 14. A rotary support 13 is mounted upon the pins 14 and is interposed between the two pairs of segments 16, 16 which are formed with weighted arms 17, 18 each of the former pair being heavier than each of the latter. Mounted upon the periphery of the rotary support 13 are adjustable rings 40, 41 that have leaf-springs 42 riveted thereto and bearing upon the outer surfaces of the two pairs of arms 17, 18, so that the spring leverage on the latter may be altered by moving the position of rings 40, 41, in respect to the arms 17, 18. At a predetermined speed centrifugal force causes the arms 17 to pivot outwardly thereby causing the driven member 12 and in consequence the ignition to be advanced. At a given higher speed the two arms 18 pivot outwardly and the driven member 12 is caused to be retarded compared to the driving member 11, thereby giving rise to retarded ignition.

Filed: 1963-04-02
Abstract: 1,015,807. Combination locks. G. E. TEGERDINE and L. TEGERDINE. June 26, 1964 [April 2, 1963], No. 13054/63. Heading E2A. A combination lock comprises a body 1 with a locking member 13 which is normally restrained from movement from the locking to the unlocking position by an abutment 37 carried by each of at least two discs 3, the locking member passing through said locking discs with the abutments 37 engaging detents 17 on the locking member, rotation of each locking disc to a predetermined position with respect to the member 13 removing the abutment 37 from engagement with the detent 17 on said member and thereby releasing the member 13 for movement to the unlocking position, each locking disc comprising an outer part 25 and an inner part 26 carrying non-rotatably the abutment 37, interengaging means (c) being provided on the two parts to allow the inner part to be positioned partly within the outer part in one of a plurality of predetermined rotational positions. In the first embodiment four locking discs 3 are positioned between two arms 4, 5 of the body 1 and the article to be locked e.g. a gear lever is clamped by a part 9 between arms 5, 6. The rodshaped locking member has a series of detents formed by annular recesses 17 and a key-way 19 (Fig. 7 not shown) interconnecting such recesses. One end of the locking member engages a recess 16 in arm 6 and the other end has an operating disc 20, complete withdrawal of the locking member being prevented by a plate 21. The two parts of the locking disc are fixed together by a portion 41 on the inner part engaging one of a series of rebates on the outer part. The outer periphery of each outer part has indentations 31 which correspond to the rebates and which are adapted to engage spring biased balls 23 in the housing 1. The two parts can be fitted together in any one of ten positions giving different positions of the lug 37. The locking member can only be removed from its locking position when all the lugs 37 are aligned with the key-way. In this embodiment the recesses 17 and the lugs 37 have one chamfered surface to allow the member 13 to be inserted even if the lugs are not aligned.  In a second embodiment the lock is adapted for use with a motor-vehicle ignition switch. In this embodiment only three locking discs are used between the arms of a U-shaped body member and the locking member 13 extends in one of its positions beyond the arm 5. Since the recesses 17 are not chamfered the locking member is locked against movement in either direction. In its extended position the locking member engages the switch and it may then be rotated to operate the switch.

Filed: 1974-03-25
Abstract: 1442047 Valves; load responsive brakes WABCO WESTINGHOUSE 25 March 1974 [26 March 1973] 13072/74 Headings F2V and F2F A valve for producing an output pressure as a function of axle loading for a vehicle braking circuit, comprises a membrane 2, Fig. 1, separating a chamber 6 connected to atmosphere from a chamber 7 in which the output pressure is derived. The valve is shown in an equilibrium position for a given loading. However, any out-of-balance due to variation in the loading causes axial displacement of the membrane. An axially movable element 5 co-operates at its upper end with the membrane to regulate flow from chamber 7 to an exhaust chamber 9, and at its mid-portion with a seating 11 to control the supply of compressed air from a chamber 12 to the chamber 7. To keep the region of the membrane that co-operates with the element 5 substantially flat, a channel 15 is formed in a backing plate 4 so that the pressure differential across the membrane forces it into the channel as shown to maintain the said membrane region in tension. The element 5 is mechanically biased upwardly by a light spring 14 and downwardly by a pusher and/or one or more springs acting on the plate 4. In an alternative embodiment, Fig. 2 (not shown), the element (5) is of solid form and the chamber (7) instead exhausts to the chamber (6) via passages formed at the centre of the membrane and plate.
