Title: Improvements in lubricating means for telescopic spring suspensions
IPC: F16N9/04
Filed: 1952-06-20
Abstract: 722,136. Lubricating. AUTO UNION GES. June 20, 1952 [June 21, 1951]. No. 15623/52. Class 12 (3). In lubricating means for telescopic spring suspensions, particularly but not exclusively for motor vehicles, lubricant is supplied by a piston pump actuated by the springing movements of the suspension, the piston rod being formed in a tube provided at or near its lower end with one or more inlet ports for lubricant, and the ports being associated with means whereby they are closed automatically on recoil of the springs. As shown, a tube 10 houses coiled springs 11, 12 and a hollow piston rod 13 formed with openings 16 and closed at one end by a disc 14 which is flattened at the sides 20, 21 for the passage of lubricant. A flanged sleeve 15 which functions, as a piston has limited sliding movement on the piston rod, abutting at one end against the disc 14 and at the other end against a circlip 19. The tube 10 is slidably mounted in bearings 22, 23 formed in a tube 24. A bellows 25 for holding lubricant connects the lower ends of the tubes 24, 10. When these tubes are telescoped together' the lubricant flows through apertures 28 into the tube 10 and through openings 16 into the piston rod 13. On recoil, the piston 15 closes the openings 16 preventing return of the lubricant. The lubricant with or without air, gradually rises in the rod 13 and overflows through openings 27 to points requiring lubrication. In an alternative arrangement the piston 15 is dispensed with and the disc 14 is constructed to act as a piston, the disc being provided with a one-way valve which allows lubricant to enter the piston rod.

Title: Improvements in or relating to protective apparatus for alternating-current systems
IPC: G01R29/16
Filed: 1931-05-28
Abstract: 379,354. Protective cut-out systems. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Fortescue, C. L.; 1013, Heberton Street, Pittsburg, and Evans, R. D. ; 1125, Milton Street, Swissvale, both in Pennsylvania, U.S.A.) May 28, 1931, No. 15632. Convention date, June 16, 1930. [Class 38 (v).] In the protection of polyphase feeders and apparatus using combinations of resistance and inductance to segregate the positive, negative and zero phase-sequence components of the phase currents and/or voltages, polyphase relays operated by the phase-sequence components are employed instead of a number of single-phase elements. In the arrangement shown in Fig. 1, the three current transformers 12, 13, 14 have their ends connected respectively to two impedance networks 16, 18 designed to segregate the negative phasesequence component and the positive phasesequence component respectively. A threephase relay 17 is connected as shown to the network 16 and a similar relay 19 is connected to the network 18. In order to deal with earth faults and render the protection complete, a single-phase relay 21 has its coil 22 connected between the star points of the two relay windings so as to carry a measure of the zero phasesequence component. Two series transformers are adequate in an arrangement wherein the three-phase protective relays are delta-connected. In a modification, Fig. 5, the segregating networks are split up and associated with the several windings of the polyphase relays, the windings a, b, c being those of the negative phase sequence and a<1>, b<1>, c<1> those of the positive phase-sequence polyphase relay. Instead of segregating current components voltage components may be segregated and the polyphase relays connected in the same way. An arrangement is shown in Fig. 12 in which the three-phase stators a, b, c and a<1>, b<1>, c<1> of two three-phase relays 63, 64 are energized by the positive and negative phasesequence voltage components derived from the networks 56, 58 while the rotors S, U, T and S<1>, U<1>, T<1> are energized by the positive and negative phase-sequence components of current derived from the networks 76, 78. The threephase relays 63, 64 may be of the watt-relay type or of the impedance type. A zero phasesequence relay 60 with windings 57, 59 between the star points of the three-phase relay windings and the star points of the voltage and current transformers may be added to act as an impedance relay and provide a time element of operation dependent on the distance of the fault. An arrangement is also described, Fig. 13 (not shown), based on that shown in Fig. 1, in which a single three-phase relay with threephase stator and rotor provides the complete protection. It is stated that the connections described are suitable for operating measuring instruments or regulating apparatus.

Title: Improvements in or relating to gyroscope controlled indicating instruments
IPC: G01C19/44
Filed: 1953-06-05
Abstract: 772,005. Gyroscopic apparatus. GOGGIN, A. H. Sept 3, 1954 [June 5, 1953], No. 15638/53. Class 97(3) A gyroscopic attitude-indicating instrument comprises a gyro rotor, two gimbals movable about mutually perpendicular axes in which the rotor is supported, centring devices for each of the gimbals for bringing them in a normal position with respect to the gyro rotor, and an operating member for the two centring devices, said member being a rotatable rod having two parts axially slidable but engaged rotationally one with the other, one part operating the first centring device when rotated and the other part operating the second centring device when slid axially, the latter part of the rod having a locking pin which normally abuts a fixed shoulder and requires rotation to free it for axial sliding, so that the operating rod as a whole must be rotated to centre the first gimbal before it can be slid axially to centre the second gimbal. The gyro rotor is pivoted in an inner gimbal ring 3, Fig. 2, pivoted in an outer gimbal ring 2 which is in turn pivoted in a housing. Gimbal 2 carries a heart-shaped cam 4 the periphery of which can be engaged by a roller 5 on a rockable arm 6. The shaft of arm 6 carries another arm connected by a link 8, Fig. 1, to an arm on a tube 11 journalled in the outer casing. A rod 12 with a knob 10 slides telescopically within tube 11 and has a pin 18 moving in a slot in the tube 11. In normal position, the pin 18 engages the shoulder of a cam surface 17 fixed to the outer part of the casing. After the gyroscope has been toppled it may be caged by rotating knob 10 which rotates the tube 11 and rocks the arm thereon, and through it the arm 6 against action of a spring 19. This forces the roller 5 against the periphery of cam 4, returning gimbal 2 to its normal position, in which roller 5 enters the recess 7 in the cam 4. The rods 12 can then be pushed against spring action within the tube 11. A plate 13, attached to rod 12, has a V-shape leading edge which engages a pin on the inner gimbal 3, thus caging this gimbal also.

Title: Motor drive control arrangements
IPC: H02P7/00
Filed: 1974-04-11
Abstract: 1486428 Automatic control systems INTERNATIONAL COMPUTERS Ltd 9 April 1975 [11 April 1974] 16249/74 Heading G3N A control system for driving a motor according to a predetermined speed curve includes a counter that produces a motor drive signal when it reaches a pre-set count, and means to adjust, in accordance with the speed curve, the number of pulses to be counted before the pre-set count is attained for example during motor acceleration. In the embodiment, a stepping motor driving paper in a computer line printer follows a speed profile that is derived from a desired feed step. A start signal at 8 sets step counter 5 and initiates free-running oscillator 1. Timing counter 2 then counts the oscillator output pulses starting at a given value from read only memory 18. When a pre-set count is reached, counter 2 provides a pulse to motor drive 7 to step the motor and sends a carry pulse to step counter 5. The starting value from memory 18 is then changed by counter 5 so as to reduce the time between adjacent drive pulses from counter 2 i.e. to accelerate the motor. The motor follows the speed profile until the output of counter 5 reaches the end of the acceleration period, when comparator 15 blocks pulses from counter 5 to memory 18 using gates 20. The starting value from memory 18 is thus held and the motor runs at constant speed. During this time, the motor drive pulses from counter 2 continue to step counter 5 until its output reaches the start of the derived decelerating profile, when comparator 15 opens gate 20 to allow the motor to be decelerated along the profile. The speed profile may have the constant speed portion omitted, and the desired acceleration differ from the deceleration. Alternatively, the counter 5 may be stepped by an encoder driven by the motor, and the read-only memory replaced by a diode matrix.
