Title: Improvements in or relating to pressure ratio control devices more particularly for aircraft air conditioning systems
IPC: B64D13/04
Filed: 1950-02-27
Abstract: 724,076. Elastic-fluid turbines. GARRETT CORPORATION. Feb. 27, 1950 [May 3, 1949], No. 4958/50. Class 110 (3). [Also in Groups X, XIII and XXIX] A regulating valve 15, Fig. 1, in the inlet 14 of the turbine 11 is regulated by means 18 responsive to the ratio of the pressures at the inlet and outlet of the engine and operative to control the ratio of these pressures. The cooling turbine 11 supplies an aircraft cabin or other enclosure 10 with cooled air and drives a fan 19 drawing coolant air through a heat exchanger 12. The valve 15, which may be of the butterfly type, is biased by a spring to the open position and closed by pneumatic pressure on a bellows 61 arranged in a casing 60. The means 18 comprises a housing 23, Fig. 2, with chambers B, C separated by a diaphragm 26 and connected by pipes 22, 21 with the cabin 10 and the inlet pipe 14 respectively. The chamber C communicates through an axial aperture 29 with a larger chamber containing an evacuated bellows 40 loaded internally by a spring 43. The head 41 of the bellows is adjustably connected to a screwed spindle 30 to the head of which the diaphragm 26 is clamped. The base 42 of the bellows is secured to an adjusting screw 44 mounted in a nut 45 and also carrying a lock nut 46. The nut 45 is held by a locking cap 49 secured by screws 51. The head 41 of the bellows is adapted to open a spring-loaded needle valve 32 supplying the bellows casing 60 through a connection 34 and a pipe 17. The housing 23 has similar connections 35, 36 for the pipes 21, 22 respectively. If the nut 45 is held stationary and the screw 44 is rotated, the position of the diaphragm 26 relative to the head of the bellows is adjusted and this affects primarily the slope of the curve formed by plotting the inlet pressure against the outlet or cabin pressure. The spring load on the bellows is adjusted by rotating the nut 45 and holding the screw 44 stationary. The latter adjustment primarily affects the position of the curve referred to above. By means of the two adjustments, the pressure ratio may be maintained constant or arranged to decrease slightly as the aircraft ascends.

Filed: 1967-02-02
Abstract: 1,163,814. Press brakes; guillotines. DOUGLAS BARNES Ltd. 24 Jan., 1968 [2 Feb., 1967], No. 5125/67. Headings B3E and B3W. A press brake or guillotine has the movable beam operated by a single fluid piston-cylinder unit slung between two bell crank levers pivoted to the machine frame and adapted to rotate the levers in opposite directions, through a mechanism comprising an operating link pivotally connected to each lever and the beam, and an angled tie-link extending between one of the levers where it is connected to the piston-cylinder unit and an integral tail part extending radially from the pivot of the other lever. The fixed tool 2 is mounted on the base 1 of the machine and the movable tool 5 is mounted on the ram 4. Above the ram is an hydraulic piston and cylinder unit 7, the cylinder of which is pivotally connected at 14 to a bell crank 8 which is pivoted at 10 to the machine frame. A link 20 connects the point 18 of the bell crank to the ram 4 at 22. The outer end of the piston-rod is connected to a similar bell crank 9 and link 21. Also connected to the outer end of the piston-rod, at the pivot point 16 is a tie-link 24, the other end of which is connected at 25 to a depending arm 26 of the bell crank 8, so that the thrust is equalized between the two ends of the ram. The radii of the points 14, 25 and 18 from the pivot 10 are equal, and are also equal to the radius of the point 16 from the pivot 11. The radius of the point 19 from the pivot 11 is slightly greater than that of the point 16 and this compensates for the fact that in its uppermost position the beam is not parallel to the lower tool. The pivot connection 23 includes an eccentric to permit initial adjustment of the rake angle of the ram. The tie-link 24 may comprise two parallel links and the cylinder unit 7 may be replaced by two cylinders in parallel, Fig. 3, (not shown) or by a single cylinder containing two oppositely moving cylinders, the pistonrods of which project from opposite ends of the cylinder, Fig. 4 (not shown). In a press brake, stroke limiting screw adjustable stops 27, 28, 29 are provided and in a guillotine these are omitted and hold-downs are provided. The stroke of the beam is also controlled by electric switches 30, 31 actuated by means 33, 34, Fig. 2 (not shown) on the ram and controlling fluid valves in the cylinder unit circuit. .

Title: Improvements in or relating to centrifugal pumps
Inventor: CARTER JAMES C
IPC: F04D29/44
Filed: 1953-02-24
Abstract: 722,677. Centrifugal pumps. THOMPSON PRODUCTS, Inc. Feb. 24, 1953, No. 5130/53. Class 110 (1). A centrifugal pump comprises a casing having a central inlet, a peripheral outlet, and nested concentric diffuser and trough-shaped pumping chambers. The casing of a centrifugal fuel pump, Fig. 1, comprises a part 12 containing the inlet 42, and a part 13 carrying a shaft bearing 19 and a seal assembly 21. The casing part 13 is attached at a circular flange 18 to an electric motor, turbine or other driving means. The casing part 12 is attached to the casing part 13 by studs 32 which enter the thickened ends 31a of diffuser vanes 31. Fuel discharged by the pump impeller 22 is guided into the axial direction by the diffuser vanes 31, which extend spirally along the inner wall of casing part 13. The fuel then passes inwardly to an annular channel or trough 35 formed in the casing part 12, and is discharged into the pump outlet 33 through an opening 38. Pumped fuel leaking back to the inlet through the running clearance between a wear ring 39 on the impeller and a bearing ring 40 on the casing part 12 is deflected by a stationary ring 41 back into the eye 22e of the impeller. The periphery of the axially extending flange 41a of the ring 41 is tapered so as to provide a diverging path between itself and the impeller eye 22e, whereby the leaking fuel is slowed before entering the slower moving stream of incoming fuel at the inlet. The injector action exerted by the leaking fuel in its passage into the impeller eye 22e assists the flow of the incoming fuel and helps to prevent the pump from losing its prime through the accumulation of vapour at the inlet. Drain plugs 29 and 44 are provided; the former may be replaced by a tube. In the modification shown in Fig. 5, the diffuser vanes 55 are formed on the inlet part 52 of the casing, while the annular channel 63 which receives the discharge from the diffuser vanes is formed on the casing part 51 which houses the shaft bearings 57. Relative rotation between the casing parts 51 and 52 is prevented by a hollow pin 69 which provides a drain passageway closed by a plug 70. Holes may be provided through the impeller to equalize the pressure on the two sides of the impeller and to return the leakage past a bearing ring 67 back to the inlet. The pump is driven by an air turbine 59.

Abstract: 267,902. Westinghouse Lamp Co., (Assignees of Marden, J. W.). March 20, 1926, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-In introducing potassium, caesium, rubidium or barium into containers such as those of discharge devices, for example, to clear up residual gases in evacuated containers, to purify rare gases in gas-filled containers, to activate electron-emitting filaments, to lower the starting and operating potentials of discharge lamps, rectifiers, &c., and to create a metallic atmosphere, a non-hygroscopic, anhydrous compound stable at normal temperatures under atmospheric conditions is introduced and subsequently decomposed to liberate the pure metal. The deleterious effects of accidentally-introduced water vapour, such as oxidization of thoriated tungsten cathodes, are thus avoided. The finely divided compound may be heated with a finely divided, stable, moisturefree reducing agent, the products of the reaction not being volatile. The compounds may be chromates, bichromates, trichromates, permanganates, or double halides such as potassiumzirconium or caesium-uranium or caesiumzirconium fluoride and the reducing agent may be magnesium, aluminium, misch metal, iron, nickel or calcium. With the double halides, magnesium or aluminium or misch metal in molecular or greater proportions may be used; with caesium permanganate, powdered iron or nickel; and with caesium bichromate or trichromate, misch metal. The mixture may be applied with a binder to a part subsequently heated or may be enclosed in a metal tube of low melting-point drawn down and cut into lengths to form capsules which are welded to ametal part of the device and heated by highfrequency induction to melt the capsule and produce the reaction. In making caesium radio amplifiers, caesium permanganate or.bichromate may be mixed with misch metal, iron or aluminium so that oxygen is liberated during the reaction to oxidize the surface of the tungsten filament to facilitate the retention of a caesium film, the usual introduction of oxygen being avoided. Specifications 14121/00 and 2901/13, [Class 39 (ii), Electric lamps, Incandescent], arereferred to. The Specification as open to inspection under- Sect. 91 (3) (a) comprises also the introduction of active metals generally and the use of compounds decomposed by heat. This subject-matter does not appear in the Specification as accepted.
