Title: Improvements in rate gyroscopes
Inventor: HUNN BERNARD ALBERT
IPC: G01C19/42
Filed: 1959-11-19
Abstract: 926,100. Gyroscopic apparatus. VICKERS AIRCRAFT (HOLDINGS) Ltd. Nov. 16, 1960 [Nov. 19, 1959], No. 39318/59. Class 97 (3). A rate-of-turn gyroscope comprises a rotor 11 mounted on the output shaft 12 of an electric motor to the casing of which a rotor cage 14 is rigidly secured. The rotor 11 comprises a heavy metal annulus 15 carried by a disc 16 of rubber contained within the annulus and supported at its centre on the shaft 12. Two piezoelectric crystals 17, 18 are attached at the front surface of the disc 16 and extend in radially opposite directions. Electric connections to the surfaces of the crystals 17, 18 are made by conductors 19, 20, 21 which connect the crystals to a commutator 22 carried on the rotor axle 12 and contacted by wipers 23, 24, 25 mounted on the rotor cage 14. The wipers are connected to a balanced amplifier 26. If the apparatus is to be used for measuring the pitch and yaw of an aircraft it is mounted in the aircraft with the rotor axis 12 in the direction of the aircraft body axis. Deviation of the aircraft from its datum position sets up a precessional torque in the rotor 11 which causes deformation of the rubber disc 16. As the rotor is spinning, each elementary part of the disc 16 first undergoes bending in one sense and then bending in the opposite sense, and this alteration of bending occurs at the spin frequency of the rotor. The bending variations are transformed by the opposed crystals 17, 18 into electric signals with a maximum amplitude corresponding to the maximum bending of the disc at the crystal positions. As the crystals are at diametrically opposite positions of the disc, the oscillatory signals are 180 degrees out of phase, giving a double-amplitude signal in the amplifier 26 which is fed to an amplitude detector 27 and phase comparator 28. The amplitude of the output signal is a measure of the magnitude of the precessional torque and hence the rate of turn. The phase of the signal in relation to a fixed datum signal provides an indication of the direction of the axis about which the applied torque acts and hence the direction of the rateof-turn axis.

Abstract: 1,212,675. Pump control systems. DOWTY HYDRAULIC UNITS Ltd. Dec.4, 1967 [Sept. 9, 1966], No.40421/66. Heading G3P. [Also in Division F2] In a hydrostatic transmission for a cable winding drum comprising a fixed or variable displacement motor 2 and a variable displacement pump 1 adjusted by an hydraulic servomotor, the pump displacement is reduced if the pressure in the transmission flow line becomes excessive. In Fig.1 pump displacement is variable from zero in one direction only by a servopiston 14 which is biased to its zero displacement position by a spring 17. The lower end of the servo cylinder is connected to an input driven pump 5 by a fixed restriction 18, and the upper end of the cylinder is connected to a line 9 which supplies make-up fluid to the return transmission line 4. The pump 5 is connectable to the line 9 by a variable throttle 8 which is settable to determine the pump displacement. A valve 21 has ports 32, 33 leading to each side of the cylinder and is subject to the pressure of the transmission flow line 3 such that above a predetermined pressure a valve spool 25 is raised to inter-connect the ends of the servo cylinder so that the pump displacement is reduced. As shown in Fig. 2 the pump displacement is variable either side of neutral by a servopiston 14, the ends of the servo cylinder being connected to the output of pump 5 through fixed restrictors 43,44. A rotary control valve 46 has ports 51, 53 connected to the ends of the servo cylinder and a port 52 connected to the transmission make-up line 9 and is operable to selectively provide a restricted path between ports 51 or 53 and the port 52 to adjust the pump displacement. The ends of the servo cylinder are also connected to chambers 63, 64 of a valve 61 which has a plunger 68 subject to the pressure in the transmission line 3 acting on a spring end cap 69. A hollow plunger 73 is biased upwardly by a light spring 74 and has a relay valve 78 mounted within it. When the control valve 46 is adjusted for forward drive, the lower end of the servo cylinder is at reduced pressure and the full servo pressure is exerted in the chamber 63 to move the hollow plunger 73 downwardly. At a predetermined pressure in the transmission line 3, plunger 68 shifts upwardly and a projection 85 on the spring end cap raises the relay valve 78 which then inter-connects the ends of the servo cylinder so that the pump displacement is reduced. If the transmission pressure is to be limited during  reverse drive a second valve 61 may be provided to respond to the pressure in the line 4. Specifications 1, 212, 673 and 1, 212, 676 are referred to.

Abstract: 1462180 Slack-adjusting brake transmitting mechanism TWIFLEX COUPLINGS Ltd 15 Aug 1974 [28 Aug 1973] 40444/73 Heading F2E A brake actuator includes a diaphragm acting on a slide rod to which a push rod is screwed, the two rods being relatively rotated during the return stroke when the actuating stroke length exceeds a predetermined value and being coaxial with the line of action of the diaphragm. As shown a brake is applied by downward movement of a push rod 22, non-rotatable relative to a casing 1, on pressurization of a diaphragm chamber 6. On excessive movement due, e.g. to brake-pad wear, a pivoted and spring-loaded pawl 31 rides over the next tooth on a ratchet ring 30 secured to a cylinder 18, secured in turn to a slide rod 14 acted upon by the diaphragm 5. On brake release, and consequent return of slide rod 14 by a spring 20, ring 30, and consequently slide rod 14, is forced to rotate, so push rod 22 is screwed out slightly by threaded connection 25 with slide rod 14. The effective length of the combination 14, 22 thereby increased. A resilient, rather than a pivoted pawl may be used. Instead of fluid pressure, brake application may be by a spring located above diaphragm 5, in which case release may be by fluid pressure under diaphragm 5 (Fig. 4, not shown) or by electromagnetic attraction, spring 20 being dispensed with in these cases. In Fig. 6 (not shown) the ratchet ring secured to the slide rod is acted upon by a further ratchet ring rotatable on the slide rod, spring urged towards the further ratchet ring and rotated in opposite directions on actuation and release by engagement of projections on it with a helical groove in a fixed part.
