Patent GB-2459415-A (GB)
Title: Hydraulic actuator
Inventor: HANKINSON CHRISTOPHER
IPC: F15B13/04
Filed: 2008-03-05
Abstract: A double-acting actuating device (1) has a cylinder (2) with a piston (3) connected to a rod (4). The cylinder is provided with ports (8,9) at opposite ends for flow/return lines (10, 11) to provide flow of hydraulic liquid to whichever side of the piston is to be pressurised for its movement and to provide return of hydraulic liquid from the other side. The lines (10, 11) pass to opposite ends of a shuttle valve (20) having a body (21) with a bore (22) accommodating a double acting piston (23) having short rods (24, 25) extending on either side. Each rod carries a centring spring (26, 27) acting against its face of the shuttle piston and an end fitting (28, 29) of the body. The springs are relatively stiff and centralise the shuttle. The fittings seal the bore, except that each has a central drilling (30) which can freely accommodate the rod on its side of the piston and allow hydraulic liquid flow at the same time. Outwards of the drilling, each fitting has a tapered bore (31) for receiving a non-return valve ball (32) held against the bore (31) by a spring (33). The bore has two ports (35, 36) respectively close to the end fittings (28, 29). The body (21) of the shuttle valve has two ports (61, 62), opening into the bore (22) adjacent the end fittings (28, 29), to which ports are connected flow and return lines (63, 64) from a reversible gear pump (65), selectively driven in either direction by an electric motor (66). In normal operation, the pump is driven in the direction required for the desired movement of the actuator, as a whole. Flow of hydraulic liquid is to one end of the shuttle valve. The pressure of the liquid lifts the valve in the respective end fitting (28, 29). Pressure is applied to the actuating device and via its piston to the liquid in the respective line back to the other of the fittings. Until the valve in this fitting is opened no movement can occur. The pressure acts on the shuttle, moving it towards this valve, which it opens via its rod (24, 25), the effective area of the balls (33) seating in their tapers (31) being less than that of the shuttle piston. Movement can then occur with the return of liquid back to the pump and piston rod effect flow to or from the accumulator via the line (75).

Abstract: 696,641. Cutting-apparatus. ADHESIVE DRY MOUNTING CO., Ltd., and DOHERTY & SONS, Ltd., E. April 30, 1952. [April 30, 1951] No. 10041/51. Class 31 (i). In an edge trimmer of the guillotine type, a work clamp is normally biased to the clamping position and the pivoted cutter blade has a projection near the pivotal axis thereof which, near to the completion of the upward stroke of the cutter blade, operates a clamp-actuating member to cause the work clamp to be moved to an inoperative position. In the form shown in Fig. 1, a work-clamping bar 7 is located above a fixed blade 3 and is supported at its ends on rods 5 extending upwardly from the ends of a bar 6 which is biased to a lowered position, corresponding to the clamping position of the bar 7, by means of springs 10. The movable cutter blade 11 is pivoted at 13 and is formed with a tail 14 having a cam edge 15 which, when the cutter blade 11 is raised, depresses the end 16 of a pivoted lever 17 thereby raising the bar 6 and moving the clamping bar 7 to its inoperative position. The upward movement of the pivoted blade is limited by the engagement of a shoulder 22 on the tail 14 with a stop bar 21. The pivot 13 may be provided with a torsion spring when tends to move the blade 11 towards its raised position. In a modification, Fig. 3, the clamping bar 7 is carried by a pivotally-mounted rod 23. One end of the rod carries a spring-influenced bellcrank lever 25 one arm 26 of which is depressed by a tail 14, when the pivoted blade 11 is raised, so as to move the bar 7 to its inoperative. position. A stop 21 limits the upward movement of the blade 11.

Abstract: 1306258 Pressure gauge AGA AB 4 March 1970 [1 April 1969] 10342/70 Heading G1L A pressure gauge 1 comprises a body 6 in a chamber 2 to which a medium under pressure may be introduced, the body having a part 4 projecting through an aperture in the housing to indicate on a scale 5 the pressure applied to the chamber, there being means in the chamber and in contact with the body which moves relative to and simultaneously with the body due to changes in the pressure in the chamber whereby the body and the means take up relative positions dependant on said pressure which is indicated on its scale by the projecting part of the body. A medium under pressure admitted to chamber 2 in housing 1 through inlet 8 exerts a force on a liquid 7 (for example mercury) in the chamber and causes a member 6 having an extension 4 to rise in the liquid and indicate the pressure on a scale 5. The opening 3 may be sealed with a liquid film Fig. 6, 7 (not shown). The gauge is zeroed by means of wheel 9 and plunger 10. To prevent loss of fluid if the pressure is too high for the range of the gauge and to prevent admission of air if the pressure is too low, O-rings 19,17 can seal the opening 3 of the chamber. Temperature and pressure compensation is achieved by providing additional chambers (13) connected at the top and selectively connectable at the bottom to a chamber 2 Figs. 2-4 (not shown). The scale might be fan shaped and movable laterally to compensate for temperature changes. The liquid may be omitted, a freely movable body (4) being retained and its movement controlled by heavy chains (20) Fig. 8 (not shown),

[Class 51 (i)] [See also Group XXVII] In a combustion-product plant in which gases generated by the firing of a combustible charge are led through a conduit to a prime mover such as an engine, engine-starter, or launching or projecting device, a normally open exhaust valve on the conduit is closed by the operation of firing means for the charge. In one form, Fig. 1, a cartridge c is fired in a combustion chamber a communicating through a conduit f<1>, f<2> with the prime mover to be operated. A balanced valve e controlling an exhaust conduit f<3> is normally held open by a weak spring g. Breech mechanism b of the Farman pistol type is fitted with a firing-pin actuated by a trigger k on a lever i, the first movement of which causes a shoe i<1> to actuate the valve e through a spring head h to close the exhaust conduit f<3>. In the case of a sustained firing stroke, the valve e may be held automatically in the closed position by a lever and ratchet mechanism attached by means of a flexible link or otherwise to the lever i. In a modification, the breech mechanism is of the Very pistol type and an expansion chamber h is interposed between the combustion chamber a and the conduit f<1>. A grid may be arranged between the combustion and expansion chambers. A safety valve l, Figs. 8 and 9, may be fitted on the conduit f<2> leading to the prime mover, in which the pressure lifts a spring-pressed piston l<1> to uncover vent holes l<3>.

Abstract: 493,772. Cutting metal by fusion; blowpipe burners. LINDE AIR PRODUCTS CO. April 13, 1937, No. 10455. Convention date, April 30, 1936. Addition to 448,432. [Class 83 (iv)] [Also in Group XI] The method of cutting metal according to the parent Specification, in which supplementary heat is applied to one surface of the body being cut, is modified in that supplementary heat is applied to more than one surface of the body being cut. A single cutting blowpipe B which may have a central cutting gas passage surrounded by a number of fuel gas passages in the usual manner, is not necessarily water cooled. The work M in the form of a thick sheet is moved relatively to the cutter along .rollers 19. Preliminary heat is supplied to the work by heating tips 13 (five are provided in the example given) which project from a water-jacketed body 12, a part 14 of which projects downwards between the cutting blowpipe and the heating tips to protect the former. The oppositely disposed preliminary heating device 16 is similar to that just described, the water-cooled shield 18 in this case preventing the flame from the heating tips 17 entering the lower part of the cut and thus interfering with the cutting flame from the nozzle 15. Supplementary heat may also be supplied to the work subsequent to the cutting operation by one or more pairs of post-heating leads 20, 21. A shield 30 is used to protect the rollers 19 in the latter arrangement. The application of the invention to the cutting of a flange on aT-section beam is described.
