Title: Improvements in or relating to fluid-pressure relay apparatus
IPC: B63H25/28
Filed: 1944-11-27
Abstract: 615,619. Fluid-pressure servo motor-control systems; valves. PAULIN, J. G. Nov. 27, 1944, No. 23610. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 11, 1944.] [Class 135] In a fluid - pressure servomotor-control system, the device to be regulated is acted upon by a bellows in opposition to a spring, and the pressure in the bellows is controlled by a valve device of which the actuating member is adjusted by pressure variations in a primary fluid and by forces transferred from the bellows through the said spring in such manner that the forces acting on the valve-actuating member tend to balance out. On screwing down a hand wheel 11, a graduating spring 8 connected to a diaphragm 2 is compressed and the resultant movement, besides being indicated on scale 13, is transmitted to a bridge member 19. Spring-loaded single beat lift or ball valves 15, 16 have a lost motion tapper connected with the bridge 19. and the valve 16 will be actuated by the abovementioned movement to admit compressed air from a conduit 40 into a chamber 17 and thence through a conduit 44 to another diaphragm chamber 45. The pressure in chamber 17 is also transmitted through 'the apertures housing the legs of the bridge 19 to the lower surface of diaphragm 2, and when this pressure has built up to move the diaphragm up sufficiently to balance spring 8, valve 16 will close again under the action of its loading spring. On reverse movement of hand wheel 11, valve 15 will be opened to exhaust the pressure fluid through conduit 36 from conduit 44 and from under diaphragm 2 until the pressure once again balances the tension in spring 8. For stability of control, there is a continual leak from conduit 44 past a leakage valve 89 and through a water-filled vessel 90. The movements of diaphragm 47 resulting from variations in the air pressure in chamber 45 actuate, through a stud 48 or a bridge member 86, valves 77, 78 similar to valves 15, 16. Valve 78 controls the supply of compressed air from a conduit 76 to a bellows-enclosed chamber 81, and through a passage 70 and a conduit 68 to bellows 56, and the resultant movement of the bellows is applied to an indicating pointer 66 and through a lever 61 and a link 62 to a rudder 64. The movement of bellows 56 is also applied to diaphragm 47 through a bridge member 53 and a spring 50 to recentre valves 77, 78. Valve 77, when actuated, controls the exhaust to atmosphere of pressure fluid from bellows 56 and chamber 81. If the space above diaphragm 2 is connected to a Pitot tube, the apparatus will constitute a ship's log.

Abstract: 366,604. Rotary compressors. SANDERS, J. M., Shannon Court, Corn Street, Bristol, and TAIT, J. D., 25, Victoria Street, London. Aug. 11, 1930, Nos. 24038/30 and 9557/31. [Class 110 (ii).] A rotary compresser or exhauster comprises a multithreaded worm or spiral gear 1 and a toothed ring 4 with their axes inclined to one another, the two members fitting a casing 2, 6, and rotating in mesh so that the teeth of the ring act as pistons in the grooves of the spiral gear, to compress the fluid contained therein. The two rotors closely fit the portions of the casings 2, 6, and an oil or glycerine seal is also provided. The top casing 2 has a spigot 8 which locates the.position of the toothed ring 4, and the lower casing 6 has its walls extended upwards at 11 into the ring chamber 5, the wall on one side being cut away to provide an opening in which the teeth of the rotors mesh. Oil is fed to the space 12 from a pipe 15 and drained off through an outlet 18. The oil is carried round by the teeth to seal the spaces between the rotors, and the casing walls, and also acts as a lubricant through channels 16 and gutters 17. A groove 20 drains off oil squeezed from between meshing teeth. Air to be compressed is admitted under the ring 4 through an inlet 13 and delivered through a port situated above the ring. A packing ring 9 is provided. Plain or ball bearings may be used. The compressed air may be delivered to an oil separator. In another arrangement the axes of the ring and spiral gear are inclined to one another at an angle less than 90‹. In this case a larger driving shaft 3 can be used. Fig. 8 illustrates a further arrangement. A casing 21 contains an oil bath through which moves the toothed ring 4, which is vertical but inclined at 30‹ to the axis of the rotor. The rotor casing 22 has projecting members 25 which form bearings for a portion of the ring 4. Inlet and outlet ports 13, 14 are provided. In modified constructions, two or more rings co-operate with one spiral gear, and a corresponding number of inlet and outlet ports are provided. The latter arrangement may constitute a multi-stage compressor. A further arrangement describes a toothed ring which is cup-shaped with long teeth formed on its inner curved surface, and is thick enough to envelop about a quarter of the circumference of the gear 1. All compressors are reversible. Provisional Specification 9557 of 1931 states that the ring may have outer teeth which are driven by an external gear.

Abstract: 935,528. Dispensing measured quantities of liquid. J. LIPPMAN. June 22, 1962, No. 24207/62. Class 106 (5). [Also in Group XIV] A soap or like material dispenser comprises a support member 13 carrying a supply container 10, a passage 39 in the support member leading into an orifice 29 surrounded by a seat 43, and a reciprocable plunger 38 having a closure surface 44 which is moved into or out of engagement with the seat by actuating means 30, the plunger having openings 49, 50 for the passage of pressurized material through the orifice 29 via a chamber 48 when the plunger is moved to the open position by the actuating means. The plunger 38 is urged into the closed position shown in Fig. 3, against the action of a spring 45, by means of a closure plate 35 formed on a ring 32, the latter being rotated by means of a pin 56 engaging a shoulder 57 formed on the ring; the pin is secured to a handle 54. The material, such as liquid soap, is pressurized by means of a piston 31 which is moved downwardly by means of a threaded spindle 58 rotated by a gear drive 55 and ratchet-type clutch 59. In operation, upon rotation of the handle 54 to the chain-dotted position, the ring 32 is rotated, thereby moving the closure plate from the open end of the plunger 38 and thus allow the latter to open the orifice 29. Simultaneously with the movement of the ring, the piston is moved downwardly, thereby forcing the soap through the orifice via the openings 49, 50 in the plunger and the chamber 48. The movement of the plunger is limited by means of the closure plate 35 abutting a stop 52. Upon release of the handle 54, the ring 32 is returned under spring action so that the closure plate contacts the end of the plunger and thereby forces the closure surface 44 into contact with the seat 43.
