IPC: A62B9/02
Filed: 1954-10-25
Abstract: 783,434. Fluid-pressure servomotor-control systems; valves. NORMALAIR, Ltd. Jan. 3, 1956 [Oct. 25, 1954], No. 30641/54. Class 135. Valve mechanism for air or oxygen breathing apparatus comprises a flexible diaphragm c of which a part only communicates during inspiration with the interior of a face mask and which is connected through a lever d pivoted at e with a valve g which controls the admission of pressure air or oxygen from a pipe h to a further flexible diaphragm n which, through a lever o, actuates a main valve q to admit air or oxygen under pressure from a supply pipe p to a pipe j leading to the mask. During expiration the diaphragm c is moved to tÁe right to disengage a seating so as to permit exhaustion to the surrounding air (or water), the diaphragm c being then exposed to the expiration pressure over the whole of its area. At the same time the valve g is closed and the pressure acting on the diaphragm n escapes through a restriction k to cause closure of the valve q. The space between the two diaphragms is connected to the surrounding atmosphere or water.

Abstract: 1466203 Pistons CATERPILLAR TRACTOR CO 22 July 1975 [9 Aug 1974] 30705/75 Heading F2T A cup seal for use in an hydraulic cylinder comprises a disc-shaped base portion 21 having an integral annular flange portion 22 which sealingly engages a bore of the cylinder (not shown) and upon its reciprocation within the bore it is caused to rotate by means consisting of a series of grooves 23 obliquely disposed, relative to the axis, each groove extending from an open end at the juncture of the base portion 21 with the flange portion 22 to a closed termination at a point on the surface of the flange portion, at an axial distance L from the base portion 21. The slant angle a, Fig. 3, may lie between 10 and 45 degrees, and may typically be approximately 30 degrees. The cup seal may be composed of a cured and flexible elastomeric material, e.g. an ethylene propylene dienemodified cured rubber composition. The rubber composition may have an acrylic resin (e.g. trimethylol propane trimethacrylate) added to it to increase its hardness. The cup seal may also incorporate a cup-shaped reinforcing fabric member 24, 25, in which the fabric may be composed of a wide range of materials, among which nylon-polyester fabric and PTFE are preferred. The cup seal may be used in an hydraulic master cylinder of orthodox pattern in a vehicle braking system. Rotation of the seal minimizes wear occasioned by passage of the seal past port apertures in the cylinder wall.

Abstract: 1,102,747. Circuit assemblies. SIEMENS A.G. 20 July, 1965 [21 July, 1954], No. 30764/65. Heading H1R. An electric filter in the form of a T or TT network of lumped reactance elements provides frequency selective properties in the U.H.F. or S.H.F. bands. In Fig. 1, a band-pass filter comprising the TT network shown, for use at frequencies between 1 and 2 Gc/s., is formed on a metal base-plate 1; two rigid T-shaped stripmetal members mounted on metal carriers 2, 3 comprise conductor sections 6, 7 and lumped inductance sections 4, 5. The shunt capacitances are provided by plunger type capacitors, whose stators 8, 9 are carried on inductance sections 5, and whose rotors are formed by screwed metal pins 12, 13 connected to the baseplate 1; the dielectric may be air or a thin layer of polystyrene or PTFE. The series capacitor has a stator formed by semi-cylindrical extensions 10, 11 on stators 8, 9 and an adjustable metal pin rotor 14 attached to a screwed insulating pin 15 in the base-plate 1. Fig. 2 (not shown) depicts an equivalent T-network whose capacitor arrangement comprises a central shunt plunger capacitor having on each side a series capacitor with stators made of two halfcylinders. In a modification for use through a frequency range up to c. 10 Gc/s., Fig. 3 (not shown), an arrangement similar to that shown in Fig. 1 is mounted on an insulating carrier plate (23) which is metallized to allow capacitor stators (8, 9) to be soldered thereto and is mounted in a metal screening box (22), the conductor sections (6, 7) being connected to the inner conductors of coaxial lines whose outer conductors are connected to the screening box, as are the inductance sections (5). Alternatively, the insulating carrier plate (23) is attached to the stators at an intermediate region (Fig. 5, not shown). Modifications.-Small straight coils may replace conductor-type lumped inductance elements up to c. 10 Gc/s. Thin-walled tubular capacitor stators may be employed (Fig. 4, not shown), and they may be fixed round insulating tubes on the base-plate (Fig. 6, not shown). Fig. 7 (not shown) depicts equivalent circuit diagrams of a plurality of networks which may be realised according to the invention. ,

The pipes are supported by an up-and-down swinging boom 20, which is power-operated, and the connection 40 between the boom and the pipe is so arranged that the pipe assemblage remains in substantial balance during said up-and-down movements. Several booms may be provided, each supporting a pipe assembly, the booms being mounted on a structure 10 and being moved by hydraulic rams 22. The position of each boom may be controlled manually from a control 26. Each pipe assembly is suspended from its jib by a flexible sling 41 which passes round pulleys 42, 43, 44. The hydraulic system used to control the position of the booms 20 is adapted to supply hydraulic fluid under pressure at either a fast or slow rate to one side of a piston within the ram 22 to raise the boom, also to allow fluid to leak from the ram at a fast or slow rate to lower the boom. In addition, the hydraulic system automatically supplies or leaks fluid from the ram to compensate for changes in the relative positions of a ship and a dock between which the pipe system may be connected.

Abstract: 1442180 Colour television tubes RCA CORPORATION 3 July 1973 [3 July 1972] 31643/73 Heading H1D A colour television tube shadow mask comprises a thin metal sheet having multi-apertured masking portion 28 and imperforate peripheral portion 32 attached to metal reinforcing frame 29, portion 32 having a resistance to heat flow which is # 11 % that of a portion 32 formed by a solid sheet of thickness equal to that of the masking portion, so as to impede heat conduction between portion 28 and frame 29. A method of fabricating a temporary apertured mask for photographic production of a phosphor screen comprises applying to at least one surface of the metal sheet an organic material coating the viscosity of which is reversibly reduced by heating to provide a thin film closing the mask apertures, heating to break the thin film and form a bead inside and partially closing each aperture, and cooling to harden. The above construction ensures the outer apertures remain sufficiently heated to break the thin films, and the frame serves as a heat sink to heat generated by electrons. Skirt portion 32 in Fig. 7 has etched dimples or depressions, and skirt portion (60) in Fig. 9 (not shown) is of lesser thickness than the masking portion. Extending the lengths of portions 32 and (60) further increases the heat resistance. Alternatively, the masking portion is of a high-conductive metal such as Cu, and the skirt portion of a low conductive metal such as steel. Preferably the mass/unit area of the skirt portion substantially equals the mass/unit area of the mask portion. The mask may be 0À006-0À007 inch steel welded to a 0À93 inch steel frame. Mask apertures may be opposed cups (38), (39), Fig. 4 (not shown). Cups (38) are substantially uniform over the masking portion, while cups (39) are graded. Shadowmask apertures and frame dimensions are given. In Fig. 7, the cups extend in the same pattern as the apertures into skirt 32, the mass ratio being 57 : 62. Other ratios are given. The organic material comprising demineralized water, wetting agent, p.v.a. water solution and ethylene glycol may be applied in an upward trajectory as in Specification 1,374,728. Heating cycles are described. Reference is made to a one piece mask electrode, and also heating of the frame 29 (Fig. 11, not shown).
