Abstract: 1298677 Pressure regulating valves I V PRESSURE CONTROLLERS Ltd 1 May 1970 [10 July 1969] 34890/69 Heading F2V Outlet pressure acts on piston 23 via passage 26 to move it against the adjustable spring- loading 27 and thus allow the closure member 14 to follow the movement of the piston-rod 22 under the action of its spring-loading and so move relative to its seat 15 to regulate outlet pressure. The end of the rod 22 is shaped to co-operate with a seat 17 on the closure member 14 and if when the closure member 14 is closed outlet pressure rises the rod 22 will move away from its seat 17 to vent the outlet via passage 18. Passage 29 allows outlet pressure to act on the lower end of the closure member 14 so that it is substantially pressure balanced. Piston 23 may be replaced by a diaphragm and the loading may be a gas-loaded dome.

Title: Improvements in or relating to intermittent driving gear
IPC: F16H31/00
Filed: 1933-12-13
Abstract: 429,043. Shaft couplings. POWELL DUFFRYN STEAM COAL CO., Ltd., Tredomen Offices, and FENNELL, W. F., 10, Hillside Terrace, both in Ystrad Mynach, near Cardiff. Dec. 13, 1933, No. 35129. [Class 80 (ii)] [See also Group XXX] Relates to an intermittent driving gear particularly applicable in connection with the tipping of wagons, trucks and the like, and in opening and closing gates of tunnel ovens for firing plastics and like operations. As applied to the driving mechanism for overhead truck &c. tipplers, a horizontal shaft 10 is driven through reduction gearing 16 from a reversible electric motor 18. Two pairs of rope sheaves 20, 22 are freely rotatable on the shaft 10, and adjacent each sleeve is a crank arm 21, 23 keyed to the shaft 10. The outer faces of the sheaves 22, 20 are provided each with a spiral track 26, 24 and in each of these tracks runs a roller mounted on a pin 28, 29 carried by links 25, 27, each of which is connected to its appropriate crank 21, 23. At the outer end of each spiral track is a block 30, 31 respectively, with a recess 33, 34 adapted to be entered by the end of the link 27 to drive the sheave. Two tipping devices 36, 38, Fig. 1, are provided and have their inner ends pivoted at 140, 142 respectively near the middle of the framework 14. The outer ends of these devices each carries a pair of pulleys, one of each pair being shown at 40, 42 respectively. Four cables 45-48 are employed, each of which is attached at one end to one of the sheaves 20, 22 and after passing round one of the pulleys 40-43 has its other end anchored to the upper part of the framework 14. The length of each spiral track is such that the difference of the effective lengths of the cables when the devices are fully up and fully down is accommodated by the amount wound on or from the sheaves, so that slack is avoided. In operation, the main shaft 10 being rotated in one direction, cranks 23 and links 27 will rotate sheaves 20 or 22 in connection with one tipping device 36 or 38 say three revolutions to effect the tipping action. During this movement the rollers on the other links are travelling inwards along their spiral grooves and no motion is transmitted to their sheaves. The motor 18 is now reversed whereupon the two wound-up sheaves will rotate under load and unwind, during which movement the rollers in the grooves of the other sheaves are moving outwardly but do not impart motion until their links strike the abutments 30. Thus the raising and lowering of one device takes place while the other is at rest.
