Title: Improvements in lubricated gate valves
IPC: F16K3/36
Filed: 1952-08-08
Abstract: 718,324. Valves. VOLPIN, A. S. Aug. 8, 1952 [Aug. 27, 1951], No. 20027/52. Class 135. [Also in Group XXXIV] A gate valve comprises a closure member of two parts 21, 22, Fig. 1, spring-urged apart and slidable between seats 8, 7 under the control of handwheel 30 and screwed stem 27. Each seat has an annular groove 85 connected with a lubricant or sealing material reservoir 51 via passage 59, groove 72 and a recess 86 in the closure member only when the valve is closed, the recesses moving out of contact with grooves 85 when the valve is opened. Each seat, inwardly of the groove 85, is recessed as at 95 so that the groove connects with the flow line 3. At least the downstream reservoir is supplied with lubricant, the provision of two reservoir and sealing grooves permitting the valve to be used for flow in either direction. The lubricant is caused to flow into the groove 85 and recess 95 in the downstream seat by line inlet pressure acting on a piston 56 in the appropriate reservoir, the inlet pressure fluid moving the upstream closure member part 21 or 22 away from its seat against springs 23 and leaking into chamber 4 to act on the piston. The lubricant will steadily flow due to the groove 85 being connected with the lowpressure outlet line of the valve. Lubricant is supplied to the reservoirs through connections 62, Fig. 3, which communicate each with one of the seat grooves 72 through bores 70, 71. Specification 651,474 is referred to.

Abstract: 434,558. Water and like taps. TOTTENHAM, H. L. W., Greenwood Park, Newry, Co. Down, Northern Ireland. July 9, 1934, No. 20043. [Class 135] In a water or like tap with a screw-down valve co-operating with a seating 3 in an apertured sleeve member 2 which can be rotated to out off the water supply for facilitating the repair of the screw-down valve, the sleeve 2 projects at one end outside the tap casing 1 and is provided with an external flange 2<c> adapted to be engaged by a screwed collar 4 for securing the sleeve to the casing 1, and with flats 5 beyond the flange 2<c> for facilitating the turning of the sleeve. As shown, the sleeve 2 is tapered and is a tight fit in the casing 1. Openings 2<a>, 2<b> in the sleeve normally register with the water inlet 1<a> and outlet 1<b> respectively. When the collar 4 is slackened, the sleeve 2 may be rotated by means of a spanner engaging the flats 5 so that the openings 2<a>, 2b do not register with the water passages, and the screwdown valve can then be removed without causing water to flow. In another form, the sleeve 2 is cylindrical and has a concave inner end engaging a similarly-shaped web formed internally in the casing. Openings in the web and concave end normally are in register for allowing water to flow, but rotation of the sleeve causes the water supply to be cut off.

Title: Improvements in and relating to vibration damping devices
IPC: F16F15/14
Filed: 1936-07-23
Abstract: 478,961. Vibration-dampers. SARAZIN, R. R. R. July 23, 1936, No. 20457. Convention date, July 24, 1935. [Class 108 (iii)] In order to damp vibrations in a non- rotating body, such as an engine or machine, at least one mass is pivotally mounted eccentrically on a rotary shaft which is associated mechanically with the body so that it cannot move axially relatively thereto, the mass, however, being free to oscillate axially of the shaft. When the invention is used to damp the transverse vibrations of a number of aligned engine cylinders, the shaft may be rotated, e.g. through a gear transmission connected to the driving shaft of the engine. As shown in Figs. 1, 2 the masses 5 are enclosed in a casing 6 keyed on the shaft 4 and separated from the periphery 7 of the casing by rollers 10 which engage grooves 8, 9 in the casing and masses. In another construction, Fig. 4, each mass 5 is bifurcated to engage the opposite sides of a plate 11 fixed to the shaft 4, co-operating holes 12, 13 in the plate and mass being engaged by pins of smaller diameter than the holes to allow the necessary movement of the mass. Specification 478,962 is disclaimed. The Specification as open to inspection under Sect. 91 comprises also constructions which now form the subject-matter of Specification 478,962 referred to above and in which a mass or masses are suspended in pendulum fashion, or from two spaced pivots, eccentrically from the crankshaft axis of a reciprocating engine. It further comprises the construction shown in Fig. 1 (Cancelled) in which masses 5 are free to roll in spherical recesses in a flywheel fixed to a shaft 4 driven by an electric motor and rotatably mounted in a casing, axial and torsional vibrations of the shaft being damped by the inertia of the masses. The invention is also stated to be applicable for damping vibrations in aeroplane wings. This subject-matter does not appear in the Specification as accepted.
