Title: Improvements in fluid-operated actuators
Inventor: HOLDHAM BERT ROY
IPC: F15B11/032
Filed: 1961-10-30
Abstract: 944,631. Fluid pressure apparatus. NORTH HANTS ENGINEERING CO. Ltd. Oct. 30, 1962 [Oct. 30, 1961], No. 38743/61. Heading FIP. An actuator comprises two rams 11, 14, Fig. 1, of different area movable in a common hydraulic cylinder 11, a double-acting pneumatic piston and cylinder the piston 4 of which is connected to operate the smaller of the rams in the hydraulic cylinder, a hydraulic reservoir 18, and a passage 22 between the reservoir and hydraulic cylinder controlled by a valve 24 which, during each return stroke of the actuator, is opened by means 28 responsive to air pressure in that end of the pneumatic cylinder to which compressed air is admitted for the return stroke. The smaller ram 11 is connected to the rod 10 of the pneumatic piston 4 and extends through the larger ram 14 with a clearance 34 through which fluid can flow. The reservoir 18 is connected to the lower end of the hydraulic cylinder by a passage 20 and to the upper end by the passage 22 which is normally closed by the spring-pressed valve 24. When compressed air is supplied through a passage 6 to the upper end of the pneumatic cylinder, the piston 4 moves the ram 11 downwardly to pressurise hydraulic fluid in the upper part of the hydraulic cylinder so that the larger ram 14 moves downwardly at a low speed. The rams are returned to their upper positions by compressed air supplied to the lower end of the pneumatic cylinder through a passage 8, the pressure in the cylinder acting on a piston 28 to open the valve 24 to enable the hydraulic fluid above the ram 14 to pass to the reservoir as the ram is raised by a flange 36 on the smaller ram 11. In an alternative embodiment in which the movement of the larger ram is effected in two stages, a seal 52, Fig. 2, is provided between the concentric surfaces of the rams 11 and 14, and two passages 54, 57 connect the interior of the larger ram 14 with the hydraulic cylinder. The passage 54 is controlled by a spring-loaded valve 56, and the passage 57 is controlled by a relatively heavily spring-loaded valve 58. During the first part of the forward stroke of the actuator, the pressure within the larger ram is above atmospheric pressure and the downward movement of the larger ram draws fluid from the reservoir through the valve 24. When the larger ram encounters resistance, the pressure within the ram opens' the valve 58 to enable pressure to act in the cylinder 11 on the whole area of the larger ram, the pressure also closing the valve 24. On the first part of the return stroke, the valve 24 is opened by the pressure in the lower part of the pneumatic cylinder and the valve 56 opens so that, during upward movement of the smaller ram, the larger ram remaining stationary, fluid can flow into the larger ram. The return stroke is completed by the flange 36 engaging the valve 58 to raise the large ram, hydraulic fluid passing to the reservoir through the valve 24. The upward movement of the piston 4 is damped by a boss 42 and throttle 46.

Title: Hydraulic system for adjustable pitch aeronautical propeller
IPC: B64C11/42
Filed: 1957-12-16
Abstract: 868,419. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. Dec. 16, 1957 [Dec. 18,1956], No. 39014/57. Class 114. Variable-pitch propellers are adjusted by an hydraulic motor fed with fluid under the action of a control valve, normally adjusted by a speed governor driven from the engine, and a feathering valve. The housing 14 contains the hydraulic motor which varies the pitch of the blades 12 through suitable cam and gear mechanism. The feathering valve 32 when in its " closed position (as shown) allows communication between the fluid supply source fed to conduit 28 and conduit 28a, which leads to control valve 34, and also connects conduits 26a, 26 and 30a, 30, conduit 26 feeding fluid to the hydraulic motor to decrease the pitch and conduit 30 supplying fluid to increase the pitch. The control valve 34 when in its " central " position (as shown) terminates the flow through conduit 28a from the supply source and this valve is moved by a governor 48, driven from gearing 42, against the action of spring 52 to connect conduits 28a, 30a to provide fluid to the hydraulic motor to increase the pitch, and when the spring loading is sufficient to overcome the governor action conduit 28a communicates with conduit 26a to decrease the pitch. The supply of hydraulic fluid is provided by a main pump 62 and a standby pump 64 which deliver fluid from a tank 56 supplied by pumps 58 from a tank 54. The main pump 62 delivers fluid past filter 66 and conduit 22 to the conduit 28 which is provided with a branch conduit 94 leading to a normally closed valve 92. The standby pump 64 delivers past filter 68 to a conduit 70 which communicates when valve 32 is " closed " with a conduit 70a leading to a spring loaded valve 72 having a small orifice 88, the main delivery flows through conduit 78 to a drain conduit 80 communicating with the tank 56 while part of the flow passes through the orifice 88 to conduit 82 which communicates through passage 84 of control valve 34, when in its " central " position, with conduit 86 which leads to the drain conduit 80. When control valve 34 is moved to vary the pitch it closes conduit 82 and the pressure in this conduit increases to the value existing in conduit 70a thus allowing valve 72 to close under the influence of its spring, thus the pressure in conduit 70 increases and opens a non-return valve 74 thus permitting the delivery from standby pump 64 to join the delivery from the main pump 62 whenever the pitch is changed. Similarly, when the feathering valve 32 is " opened " conduit 70 is closed and the two deliveries combine as above. Specifications 683,906, 724,284 and 824,078 are referred to.

The orifices 16 in the plates 1, 3, 5, 7 increase in number and decrease in size in the direction of flow, so that their total area decreases and the plates 2, 4, 6 have slots 17 in their peripheries. The plates 2, 4, 6, 8 are dimpled to keep the plates spaced apart and may have a coating of glycerine. The impingement plates 2, 4, 6, 8 may be omitted and the perforated plates 1, 3, 5, 7 arranged so that the orifices are in staggered relation so that the perforated plates act also as impingement plates.

Abstract: 1,073,619. Lasers. HONEYWELL Inc. Sept. 22, 1965 [Sept. 23, 1964], No. 40349/65. Heading H1C. [Also in Division G2] In a photo-cauterizing apparatus including a coherent light source provided with an output beam focuser an auxiliary non-coherent light source is provided to pass light through the coherent light source along the direction of the output beam so that the plane in which the output beam is focused may be determined without activation of the coherent light source. Light from one end of an optically pumped ruby rod laser is focused by means of two convex lenses and a prism on to the retina of an eye and for setting up purposes an auxiliary non-coherent light source and condenser lens system is situated at the other end of the rod. Prior to activation of the helical flash tube surrounding the laser rod the auxiliary source is activated and the convex lens further from the one end of the rod is moved until the light is focused on to the required spot of the retina. General viewing of the eye is provided by means of an apertured mirror arranged at an angle at the focus of the convex lens nearer to the one end of the rod which mirror has light shone upon it from a second non-coherent light source. The appropriate energy level of the laser beam is then chosen by means of a series of different filters or apertures carried on a disc next to the one end of the rod and finally the laser is activated to produce a coherent light beam focused at the required spot.
