Patent GB-872019-A (GB)
Title: Improved hydraulic actuator
IPC: F15B21/0423
Filed: 1959-04-09
Abstract: 872,019. Hydraulic apparatus. GENERAL MOTORS CORPORATION. April 9, 1959 [April 14, 1958], No. 11995/59. Class 69 (2). [Also in Group XXVI] An hydraulically-operated actuator for use at high ambient temperatures comprises a cylinder 10 having a piston 22 forming opposed chambers 24, 26, the piston having a hollow rod 28, a ring 64 subjected to the pressure difference existing between the chambers, a passage 68 communicating with one end of the hollow rod, and a passage 74 connecting the other end of the rod with one of the opposed chambers 24, whereby the liquid flowing past the piston-ring passes through substantially the entire length of the rod. The piston is formed with two grooves in each of which are two cast-iron piston-rings 58, 60 and 62, 64, respectively. Between the rings is an annular groove 56 connected by the passage 68 to the interior of the hollow rod 28. A member 48 is press-fitted into the piston and is formed with a tube 70 which, with the rod 28, forms a space 72 extending to the closed end 66 of the rod. A nut is secured to the piston and engages a threaded-rod 42 rotatably mounted in a ball-bearing 44 in one end of the cylinder. Liquid supplied from a port 46 passes through the bearing 44 and the chamber 24 to move the piston to the right. The liquid also passes through the passages 74 and the inside of the tube 70 and through the space 72 and passage 68 to the groove 56. The pressure is therefore equal on both sides of the ring 60 but a pressure differential exists across the ring 64 since the chamber 26 is connected by passage 34 and a drain pipe 36. A metered amount of liquid determined by the flow past the ring 64 thus passes through the passage 72 to cool the rod 28. Because of the movement of the piston relative to the cylinder, the orifice constituted by the piston-ring is self-cleaning. In an alternative embodiment, the pressure differential exists across the ring 60 and the chamber 26 is connected by a passage to one end of the hollow rod.

Filed: 1955-04-27
Abstract: 770,937. Intercommunication systems. STANDARD TELEPHONES & CABLES, Ltd. April 27, 1955, No. 12185/55. Class 40(4). In a loud-speaker intercommunication system in which each station may call one or more others by means of a calling key or keys, operation of a calling key at any station renders all other stations incapable of originating a call and thereafter makes a connection to the called station, a common one-way amplifier being included in the connection between stations each of which have a talk/listen key which at a station originating a call controls the direction of amplification. Fig. 2 shows the connections between the common amplifier and transmit/ receive loud-speakers at each station, together with a calling tone generator which can be connected to the amplifier input. Fig. 4 shows the arrangement for the keys for a system having stations A, B and C, each of which has two relays H and E and all of which have relays CR and TL in common. Assuming the system is clear of calls station A calls station B by making key B to actuate relay HA, which connects up relay EB, isolates the keys of all other stations leaving station A in complete control of the system, brings the calling tone relay CR and amplifier reversing relay TL into circuit with the talk/listen key of station A, and (see Fig. 2) connects the transmit/receive loud-speaker of station A to the output of the amplifier. Relay EB connects the loud-speaker of station B to the input of the amplifier. To call B the talk/ listen key at A has a third position in which it energizes relays CR and TL to apply calling tone. In the talk position of the key relay TL is energized to reverse the amplifier. Each station has an engaged lamp and a lamp for each of the other stations, the circuits being controlled by relays such as HA, EB (see Fig. 5, not shown).

Abstract: 186,018. Ross, J. A. Mav 1, 1922. Jacks.-In jacks of the kind described in Specification 20930/13 the shell forming the reservoir is made in one piece with the part that carries the working parts, the bottom of the shell is formed by a detachable plate which acts as the base of the jack, and the passages for the liquid are formed either in the walls of the shell or in ribs formed thereon. The cylinder 1 in which works the telescopic ram is formed integral with a shell 2 closed by a detachable plate 3. The lower end of the cylinder 1 is closed by a screw plug 12 having an annular recess 13 into which opens a passage 10 formed in a rib 11 connecting the cylinder 1 and the barrel 5 of the force pump. A passage 14<x> connects the recess 13 with a vertical passage in which is a non-return valve 14. The non-return valve 15 in the main ram 16 is raised from its seating by a pin 18 on the plug 12 to permit the descent of the secondary ram 17. Liquid passes from the cylinder back to the reservoir through passages 21, 19 in ribs 22, 20, Fig. 2, on the shell 2 and a by-pass 24 in the valve 23. The passage between the upper end of the cylinder 1 and the reservoir may be formed in the cylinder wall, or in a rib on the outside of the cylinder, but preferably comprises a pipe 25 the free end of which is bent to bring it into register with the filling orifice of the reservoir to avoid any siphon action.

[Classes 80 (i) and 80 (iii)] Consists in mechanism for conveying oscillating motion and for converting oscillatory motion in a vertical plane into reciprocating motion in a horizontal plane, means being provided for adjusting the amplitude of oscillation or reciprocation. The invention is particularly applicable for actuating the inker or vibrator rollers of a printing press. Form rollers 4, 5, 6 deliver ink to a printing. form which reciprocates horizontally in contact with the undersurface of such rollers. The ink is delivered to and distributed upon the form rollers by vibrator rollers 28, 29 and these have to be reciprocated axially in opposite directions. Near the end of each roller is a peripheral groove accommodating a roller 215, these rollers being carried by opposite arms of a lever 216 having integral therewith a bevel gear 218 with which meshes a bevel pinion 220 carried by a stub shaft 219 which carries also a spur gear segment 221 meshing with a spur gear segment 222 pivoted at 223 and having an arm 224 carrying a roller 225. Oscillation of arm 224 will cause oscillation of lever 216 and reciprocation of the rollers 28, 29. The roller 225 is embraced by a fork 228 on an arm 227 secured to a shaft 226 which carries an arm 229 to which is pivoted a link 231 carrying at its lower end a roller 232 slidable along a slot in an oscillatable driving member 234.
