Abstract: 511,941. Fluid-pressure engines. UNITED AIRCRAFT CORPORATION. Dec. 22, 1937, No. 35483. Convention date, Aug. 14. [Class 122 (iii)] [Also in Group XXVII] Engines with groups of radial, multiple cylinders connected to cranks by master-rods and subsidiary link rods have the master rods and/or the cranks so arranged as to reduce vibrations due to harmonics of the torque variation. The groups are arranged so that their vibrations balance out or neutralize. In the arrangement shown in Fig. 3, the cylinders of each group are staggered with respect to the cylinders in the adjacent group. The cranks of the adjacent groups are arranged oppositely, with their master rods 22, 34 respectively as nearly as possible in coincidence. The harmonic components of the torque curves of the respective groups when added together result in a reduction of the exciting vibratory forces. In an arrangement such as shown in Fig. 2, the master rods may remain as shown, and one of the crankpins moved through 180 degrees to bring it into axial alignment with the other crank pin.

Abstract: 987,876. Impedence testing. EVERSHED & VIGNOLES Ltd. Jan. 3, 1963 [Oct. 3, 1961], No. 35626/61. Heading G1U. Apparatus for determining whether or not the line to earth loop impedance of an A.C. wiring system is above or below a predetermined safe value comprises line, neutral, and earth terminals 1, 2, 3 connectible to a system line and neutral 4, 5 supplied from the secondary of transformer 15 and to a system earth containing a loop resistance X returned to one side of the transformer primary. Neon indicators 16, 18 are connected between line and neutral and between line and earth, while a switch 10, limiter resistance 12, circuit breaker 11 and circuit breaker contacts 11a are series connected across the line and earth terminals of the apparatus; whose neutral and earth terminals are interconnected by variable resistance 20, circuit breaker 7 and circuit breaker contacts 7a. Initially the breakers are closed and on closure of switch 10 a predetermined current flows between terminals 1, 2 and sets up a voltage between terminals 2, 3. If the loop has impedance below a critical value, the current dependent on the value of resistance 12 operates breaker 11 and opens contacts 11a, while the voltage between terminals 2, 3 is insufficient to operate circuit breaker 7 and open contacts 7a. For high loop impedance the current dependent on the sum of loop impedance and resistance 12 may or may not operate breaker 18, while the voltage between neutral and earth 2 and 3 operates breaker 8 and opens contacts 7a. Operation or non operation of breaker 7 thus indicates an unsatisfactory or satisfactory value of loop impedance. The breakers may be of the hand restored toggle type.

Title: Improvements in or relating to plier-type tools for applying open ended retaining rings
IPC: B25B27/20

Abstract: 800,344. Pliers for applying split rings. WALDES KOH-I-NOOR, Inc. Nov. 22, 1956 [Dec. 7, 1955], No. 35753/56. Class 61. A plier-type tool for fitting a retaining splitring R to a shaft S has on one jaw a pocket 17 with side walls 19 dimensioned to limit the spread of the ring located in it when it has been expanded enough to slip onto the shaft S positioned in a central hole 16; the tip of the other jaw is formed as a wedge 24 which enters an opening 20 in the side of the pocket 17 to engage and extend a split 21 in the ring R. The jaw with the wedge is offset at about 90 degrees on either side of the pivot pin and the edge of the wedge 24 is inclined downwards so that it engages the split 21 with a scissoring motion which assists in holding the ring in the pocket. The pocket 17 is in a detachable holder 14 and a spring 25 keeps the pliers open when not in use. In embodiments in Figs. 3 to 7 (not shown) the wedge-bearing jaw is cranked somewhat similarly to that in Fig. 1, but is pivoted in lugs which depend on either side of the slot in the other arm of the pliers so that the ring-receiving pocket opens downwards whilst the wedge moves into the split upwardly. Because of this the edge of the wedge faces upwards in this embodiment. In the form shown in Fig. 10 the wedge 71 is on a spring-controlled arm 67 pivoted to the cranked jaw and is so placed in relation to the main pivot that the wedge moves laterally to engage and disengage the split-ring. Specification 781,550 is referred to.

Abstract: 811,706. Valves.ENGLISH ELECTRIC CO. Ltd. Dec. 6, 1955 [Dec. 10, 1954], No. 35895/64. Class 135. A valve assembly comprising a closure member 11a coacting with a seating 13c and carrying a flexible, annular sealing ring 20, clamped both to the closure member and to the seating so as to form a seal before the valve is initially opened is actuated by a piston 24 in response to the application of pressure fluid under the control of a pilot valve assembly itself actuated by fluid pressure in a bellows 32. The assembly is suitable for controlling the supply of liquid fuel for rocket propulsion in response to pressure of an oxidant, the latter being supplied under the control of a valve or a burster disc and connected to the interior of the bellows 32 which, in response to internal pressure, opens a pilot valve member 23a to admit fuel under. pressure from the inlet 13b of the main valve through an opening 17b to a passage 28c to act on the upper surface of the piston 24. At the same time a pilot valve member 26a is moved to close a vent. The rate at which pressure is built up above the piston 24 is determined initially by the restriction offered by the passage 28c but after the initial movement of the piston a closure 28d is opened to permit unrestricted flow of pressure fluid. The bellows 32 is subject to the action of a spring-loaded sleeve 25 between which and the bellows is a heat-insulating sleeve 25a. Although the main valve may be reclosed after operation it may leak slightly in the absence of the sealing ring 20, but such leakage may be prevented by arranging the ring 20 to shear in such a manner that a lip remains to form a seal against the seating 13c on closing.

Abstract: 1,267,310. Fluid-pressure servomotor systems. BENDIX CORP. July 24, 1970 [Aug. 19, 1969], No. 36048/70. Heading G3P. A hydraulic circuit breaker comprises a housing 10 with a main valve piston member 18 which is actuated to isolate a utilization outlet 16 to an actuator from a pressure inlet 12 in the event of abnormal loss of pressure either between the outlet and the actuator or in a return conduit 69 from the actuator which passes through the housing. Mounted within the main piston is an auxiliary valve piston having at least two piston elements on a common rod 30. One element 28 is responsive on opposite sides through ports 22, 24 to the pressures on the upstream and downstream sides of a flow restriction formed by a ridge 20 on the main piston. Loss of pressure downstream of the outlet moves the auxiliary piston to the right at a rate controlled by a dashpot piston 38 having an orifice 42, to a position where a second piston element 32 exhausts pressure from the left hand side of the main piston through a chamber 52 and passage 74 to the return conduit, so allowing the main piston to move to the left and shut off the outlet 16. As shown, a third piston element 34 in operated position places the right hand end of the main piston in communication with one side of the element 28. In the event of loss of pressure in the return conduit 69, a separate control piston 62, which is subjected to the pressure upstream of a check valve 68 through a passage 64, is moved to relieve the loading of a spring 58 and the auxiliary piston again operates to cause closure of the main valve piston.
