Patent GB-1220467-A (GB)
Title: Improvements in or relating to gas pressure regulators
Inventor: FARRER SYDNEY
IPC: G05D16/06
Filed: 1968-03-11
Abstract: 1,220,467. Valves. BRYAN DONKIN CO. Ltd. 6 March, 1969 [11 March, 1968; 4 June, 1968], Nos. 11818/68 and 26654/68. Heading F2V. In a valve which is adapted to regulate pressure when such pressure lies between predetermined upper and lower values, and to cutoff flow when such pressure rises above, or falls below, the predetermined values, or when a diaphragm which operates the valve in response to outlet pressure acting thereon becomes ruptured, regulation of pressure is effected by a valve member 32 whilst cut-off is effected by a valve member 34, the two valve members being interconnected by a spindle 36 and co-operating with respective ends of a bore interconnecting the inlet 12 and outlet 14. An extension 30 of the spindle 36 is connected, through an operating lever 86, a trip lever 70 and a link 72, to a diaphragm 44 the underside of which is subjected to outlet pressure, the operating lever being pivoted at 94, and the trip lever being pivoted to lever 86 at 78 and to link 72 at 76. A spring 80 extends between the pivot point 76 and a pin 82 and, under normal regulating conditions, extends below pivot point 78. With the fluid pressure within the predetermined values, the pressure at the outlet 14 acts on the diaphragm which correspondingly actuates valve member 32. Upon such pressure falling below the lower value, spring 52 moves the diaphragm downwardly and hence, via the levers and link, moves valve member 34 on to its seat. In the event of the pressure exceeding the upper value, diaphragm 44 moves upwardly with the result that valve member 32 is seated. Subsequent and further movement of the diaphragm in the same direction, causes spring 80 to move to the other side of pivot 75 and hence, by virtue of the arrangement of pivot points and the spring tension, results in valve member 32 becoming unseated and valve member 34 seated. In the event of the diaphragm becoming ruptured, the outflow from diaphragm chamber 45 results in a pressure differential being created across a spring-loaded valve member 104, which in combination with a seat 102 affords a restricted passage between outlet 14 and chamber 48, and hence in valve member 104 being seated at 102. The resulting decrease in pressure within chamber 48 results in diaphragm 44 moving downwardly and the valve experiencing a "low-pressure cut-off." In modifications (Figs. 2 to 4, not shown), the restricted flow between the outlet and the diaphragm chamber takes place either through an an aperture formed in a spring-loaded valve member or between a two-part valve member (Fig. 4) and its seat, the cut-off initiated by such valve members being of the "high-pressure cut-off" type as the valve members open and so provide a relatively unrestricted flow between the outlet and diaphragm chamber upon the diaphragm becoming fractured.

Title: Means for repeating at will any portion of a gramophone record
IPC: G11B3/08
Filed: 1934-09-19
Abstract: 441,299. Gramophones. LINGUAPHONE, Ltd., and ROSTON, J., 24, High Holborn, London. Sept. 19, 1934, No. 26857. [Class 40 (ii)] An attachment to a gramophone, particularly intended for facilitating the repeating of any desired portion of a language-teaching record, comprises a guide rail a adapted to overhang the turntable in a position adjacent to the path of the soundbox, a carriage c movable along the rail under the influence of a finger d projecting from the sound-box, and remotely-controlled means on the carriage adapted to raise the soundbox from the record, to return it to a previously played part of the record, and to lower it thereon. In the device shown, the carriage c comprises a plate e carrying a channelled member which embraces the flanged upper edge a<5> of the rail a. Pivoted at g on the plate e is a member f formed with a recess j in which the finger d engages, and a cam plate h is also pivoted to the plate e at i. The plate h, which has a curved surface h<1> engaging a screw k on the member f, and has projecting lugs n, o, is adapted to be actuated from a distance by means such as a Bowden cable l connected'to a thumb plunger m. When the plunger is operated, the cam plate h is swung upwards, thereby tilting the part f, so that the sound-box is raised. At the same time, the lug n shifts the finger d towards the right (Fig. 2) in the recess j. On the release of the plunger m, the cam-plate h returns to its normal position, and the sound-box is replaced on the record so that repetition of a previously played portion can then occur. A projection e<2> on the plate e bears on the rail a to exert a braking action during the return movement of the sound-box. The latter may be moved back through a considerable distance if required, by pulling back the carriage C, by means of the remote-control device, when the sound-box has been raised.

[Class 103 (i)] In means for preventing retrogression of vehicles or machines comprising a free-wheel device of which one part is driven by the mechanism of the vehicle &c., and the other part is normally held stationary, the holding means comprises fluid in a closed circuit provided with a valve which can be opened to permit reverse movement when desired. A free-wheel device, Fig. 3, disposed in a casing 11, bolted to the gear box of a motor vehicle has the part 15 integral with a toothed wheel 16 meshed with an input wheel of the gear box and the part 17 integral with an eccentric 18 adapted to drive a piston 22 in a cylinder 12 containing liquid. Valves 24 are normally seated so that the piston and part 17 are locked and rearward or forward movement of the vehicle is prevented according as a forward or reverse gear is engaged; By means of a cam rod 26 the valves 24 can be unseated thus permitting rotation of the part 17 and movement of the vehicle in both directions. The rod 26 may be operated by a hand or foot lever or by the change gear lever which may be in two parts 27, 29 with toothed parts 30 engaged by a spring 31. The part 27 operates the rod 26 by a cam 32 and lever 33 whereby the valves 24 are unseated in the neutral position of the part 27. The toothed engagement of the parts 27, 29 permits movement of the part 27 to the neutral position, though movement of the other part may be temporarily resisted by the gears. The free-wheel part 15 may be driven from a vehicle shaft the driving direction of which is reversed when the change gear is put into reverse and to render the free-wheel device effective to prevent movement of the vehicle in the undesired direction both in forward and reverse drive, the free-wheel part 15 may be driven from the shaft through an epicyclic gear adapted to act as a reversing gear under the control of the change gear lever.
