Title: Fluid Pressure Regulator
IPC: F15C4/00
Filed: 1968-03-13
Abstract: 1,180,512. Valves. BENDIX CORP. 13 March, 1968 [20 March, 1967]. No. 12223/68. Heading F2V. [Also in Division G3] The loading of piston 28 of a fluid pressure regulator is controlled by one or more pure fluid amplifiers 30, 40 (see Division G3). Fluid from a variable pressure source 20, e.g. a gas bottle, flows past closure 22 and ventilated disc 26 to cylinder 52, 60 which houses a spring-loaded piston 28 and which is connected at 50, 58 to the amplifiers which regulate the pressure Pr of the fluid issuing from outlet 62. In operation, an increase in Pr increases the pressure Pc at port 36 of amplifier 30 so increasing the pressure at exhaust 34 and the pressure at control port 46 of amplifier 40. Since the pressure at exhaust 44 is tied to Pr, an increase in the pressure at port 46 results in an increase in the pressure Pi at part 42 which increases the pressure in cylinder chamber 52 so moving piston 28 to the left and thereby throttling the flow past closure 22 to amplifier inlets 32, 42 and so reducing pressure Pr. Figs. 4-6 (not shown) illustrate a detailed construction using the same references as in Fig. 1. According to a modification (not shown) amplifier 40 can be dispensed with and port 34 is connected directly to chamber 52. Specification 1,136,533 is referred to.

Filed: 1918-07-31
Abstract: 138,376. Dawson, Sir A. T., and Buckham, Sir G. T. July 31, 1918. Sights.-Relates to gun-elevating gear of the kind provided with vertical deflexion gear for adding or subtracting the vertical deflexion angle to or from the angle of tangent elevation, and consists in means whereby the operation of the vertical deflexion gear causes the reading of the tangent elevation indicator to vary by an amount proportional to the vertical deflexion, so that the required vertical deflexion may be imparted by operating the tangent elevation gear until the leading of the indicator is the same as it was prior to the operation of the vertical deflexion gear. In the form shown in Fig. 1, as applied to a gun having an independent line of sight, the operation of the pointing crank-handle F imparts elevation to the sight through the shafts e, e<1>, simultaneously with elevation to the gun through gearing comprising a worm on an extension ex, Fig. 2, of the shaft e, adapted to actuate one bevel wheel of a differential gear the pinions of which rotate, the shaft F<x> carrying a pinion F' gearing with the elevating arc F<2>. The operation of the tangent elevation hand-wheel B<1> causes a worm b to rotate a worm-wheel b<1> solid with (1) the other bevel-wheel of the aforementioned differential gear for imparting elevation to the gun, and (2) a bevel-wheel bx adapted to rotate the range dial A with respect to the fixed pointer A<1> through one member of a differential gear D. The operation of the vertical deflexion hand-wheel C<1> mounted on the opposite side of the gun is adapted, through the shaft C, to actuate, the second member of the differential gear D, whereby the range dial A is rotated by an amount proportional to the vertical deflexion. By actuating the ranging hand-wheel B<1> until the reading of the range dial opposite the fixed pointer A<1> is the same as it was before the vertical deflexion gear was operated, the required vertical deflexion is imparted to the gun. A clock-spring may be provided between the casing and one of the bevel wheels of the differential gear D to take up backlash. A modification is described showing how the invention may be applied to a gun not having an independent line of sight.
