Title: Recording and measuring instrument
IPC: G01D9/28
Filed: 1946-11-12
Abstract: 641,225. Differential governors. BENDIX AVIATION CORPORATION. Nov. 12, 1946, No. 33594. Convention date, April 16, 1945. [Class 57] [Also in Groups XVI, XVIII, XIX and XXXVII] A differential governor co-operating with clockwork escapement mechanism controls a braking system for ensuring that an electric motor in a recording apparatus (see Group XIX) runs at constant speed. The electric motor drives a brake disc 82 through gearing 46, 80 between a fixed washer 83 and floating washer 84 restrained from rotation and urged toward disc 82 by a spring 86 controlled by a pivoted brake lever 87. The motor also drives a gear 91 which drives, through a spring 97, another gear 93 whose speed is controlled by clockwork escapement mechanism (see Group XVIII) and whose hub is screw threaded on the shaft of the first gear 91 and has a groove engaging the brake lever 87. Thus any fluctuation of the motor from the desired speed causes a difference in speed between the gears 91 and 93 and a consequential axial movement of the latter to adjust the brake and thence the speed of the motor.

Title: Shock absorber for aircraft landing gears
IPC: B64C25/60
Filed: 1954-11-22
Abstract: 765,815. Aircraft undercarriages. SVENSKA AEROPLAN AKTIEBOLAGET. Nov. 22, 1954 [Dec. 2, 1953], No. 33694/54. Class 4. [Also in Group XXXII] The invention relates to a shock absorber for retractable aircraft landing gear, in which liquid in a variable volume chamber 36 is adapted to act on an elastic fluid in a compression chamber 34. According to the invention, liquid can flow in one direction or the other between the chamber 36 and an auxiliary chamber 11  on extension and retraction respectively of the landing gear, and a valve device 42 is arranged to close a connection 39 between the chambers 34 and 36 when the pressure in the former exceeds that in the latter, so that when the liquid in the chamber 36 is in connection with the chamber 11 the shock absorber may be extended and retracted respectively in overcoming only the flow resistance of the liquid. As shown, the shock absorber comprises inner and outer telescopic tubes 27 and 13, extension of which is limited by a stop sleeve 16 and a rubber buffer 21. The compression chamber 34 is defined by concentric inner and outer tubes 31 and 25 which are rigid with the tube 13, and are closed at their outer ends by a piston 26 slidable within the tube 27. A floating piston 42 in the space 34 separates the liquid from the elastic fluid in the form of compressed air and also functions as a valve to control the flow through a passage 39 and a passage 38 controlled by a ball valve 40. The tube 31 contains a hollow stem 57 which is connected to a piston 63 slidable in the auxiliary chamber 11. The stem. 57 carries a plunger 58 at its lower end which is formed with a seating for a valve 52. The latter is slidably mounted in the lower portion of the tube 31, and is normally spring urged against the seating in the plunger 58. The piston 63 is connected by links 69 and 71 to an arm 72. A hydraulic jack 75 is connected between a lug 77 rigid with the cylinder 13 and a lug 89 carried by the cylinder 27. The jack 75 is adapted to be connected to a source of hydraulic pressure (not shown). In operation, when the undercarriage is extended, and under compression, due either to landings, or to normal suspension movements of the undercarriage, the arm 72, links 71, 69, and the piston 63 are in the position shown in Fig. 2 and liquid compressed in the space 36 in the cylinder 27 is forced through the passages 38, 39 to lift the piston 42 against air pressure in the space 34. On rebound, liquid is forced out of the space 34 by the piston 42, the passage 38 this time being inoperative. When it is desired to shorten the shock absorber on retraction of the undercarriage, the arm 72 is swung over from the position shown, to the position of Fig. 3. This raises the piston 63, and raises the plunger 58. Pressure is applied to the jack 75 which as it contracts causes liquid from the space 36 to be forced past the valve 52 into the hollow stem 57 and out through holes 66 into the auxiliary chamber 11.

Title: Improvements in or relating to a process and apparatus for the continuous manufacture of a polished ribbon of glass
IPC: B24B7/26
Filed: 1959-10-07
Abstract: 931,106. Control of several motors. COMPAGNIE DE SAINT-GOBAIN. Oct. 7, 1959 [Oct. 7, 1958], No. 34049/59. Class 38 (3). [Also in Group XXIII] The drive of the rollers 8 in a glass ribbon - making machine (Group XXIII) is automatically controlled by a tacho-generator T, Fig. 2, and other known means so that a compensatory force is applied to the ribbon by the rollers 8, the drive being by one or more motors controlled by varying the voltage, current, or frequency of mains supply (as by a converter group, a Ward-Leonard group, a transductor or a thyratron) to establish the motor torques as a function of the retarding effects on the ribbon of the tools 7. Fig. 2 shows a transductor comprising control, regulating and correcting windings, a watt-meter W which supplies a signal related to the power absorbed by the motor M, driving the polishing tools 7 whilst the tacho-generator T provides a signal proportional to the speed of the ribbon, these two signals being transmitted to a measuring and reference converter CM of known type. A regulating apparatus AR receives voltage signals C2 and speed signals C3 from the motor M2 of the driving rollers 8, which is itself controlled by the apparatus AR, the latter in turn receiving a control signal from the converter CM this having received a feed-back signal C1 from the apparatus AR. Specification 756,222 is referred to.

Title: Jolt ramming machine
IPC: B22C15/10
Filed: 1971-07-20
Abstract: 1352903 Foundry jolt/press moulding machines BADISCHE MASCHINENFABRIK GmbH 20 July 1971 [3 Aug 1970] 34066/71 Heading B3F A foundry jolt/press moulding machine has means which automatically alters the amplitude of jolting depending upon whether the machine is operated to compact a mould by jolting alone or by jolting with simultaneous squeezing. The machine has a jolt piston 15/anvil 7 mounted on a spring 8 below a moulding table 3 and upon a press piston 9. A press cylinder 2 is formed in the machine frame 1. The press cylinder 2 receives an annular projection 4 of the moulding table 3, while a further annular projection 5 of the moulding table 3 acts as a jolt cylinder receiving the jolt piston 15 of the jolt piston 15/ anvil 7. In operation, fluid is fed by a bore 11 to jolt control apparatus 12-25 (Fig. 2) within the jolt piston 15, the fluid passing along a bore 13 in a tube part 12, through a control orifice 26 and along a bore 14 to a chamber above the jolt piston 15, thereby to move the jolt table 3 upwards and the jolt piston 15 downwards. When the jolt table 3 and jolt piston 15 have moved a distance "a" apart fluid escapes beneath an outlet ring 17 so that the table 3 drops and the anvil 7 rises to give a jolt strike. The outlet ring 17 slides on a projection 18 of the inlet tube part 12 and is held in its lowest position by a spring 16 forcing it against an adjustable nut 19. During pressing, fluid is admitted beneath the press piston 9, which rises to entrain projection 4 of table 3 to lift the table 3. A threaded rod 21 on piston 9 lifts the outlet ring 17 compressing the spring 16 thereby reducing the distance "a" and hence the amplitude of oscillation of the jolt piston and table. The amplitude can be adjusted by altering the spacing "d" between the base of outlet ring 17 and the threaded rod 21. A plate 24 holds the square-headed end 23 of the threaded rod 21 against rotation.

Filed: 1954-11-24
Abstract: 773,518. Tanks. UNITED AIRCRAFT PRODUCTS, Inc. Nov. 24, 1954 [Nov. 25, 1953], No. 34105/54. Class 69 (1). A hopper for use in the storage tank of an engine lubricating oil circulation system comprises nested closely spaced apart. inner and outer containers defining an oil flow path between them, the outer container being provided in its base with an inlet communicating with the flow path and the inner container being provided at its base with an outlet which extends through the base of the outer container, and baffle means mounted on the exterior of the outer container defining a channel extending substantially from the top to the bottom of the hopper. In the form shown, the oil tank 25 contains a hopper comprising an outer shell 10, which is connected by an inlet pipe 14 to a valve assembly 27, and an inner shell 34, which is connected by an outlet pipe 15 to the valve assembly. A pair of baffles 16, 17 on the outside of the hopper define an open trough 23, the trough being further defined at its lower end by a bottom plate 21 with upturned portions 22. An inlet 32 from the valve assembly 27 to the tank is carried up the trough 23 and an outlet 33 connects the tank with the valve assembly. Radially-arranged fins 13 are fitted to the bottom of the shell from the opening defined by the plates 21, 22 towards the outlet 33. In operation, when the engine 31 is started, oil is supplied from within the inner shell 34 via the outlet 15, the valve assembly 27 and a pipe 29 to the engine and this oil, heated by the engine, is returned via a pipe 28, the valve assembly 27 and the inlet 14 to the space 35 between the inner and outer shells 34, 10 of the hopper from where it overflows into the inner shell. The hot oil in the space 35 warms the shell 10 and the heat tends to decongeal any congealed oil in the tank touching the shell. This decongealled oil is supplied by the trough 23 to the outlet 33 from the tank. On further running of the engine the valve assembly 27 closes the inlet 14 and the outlet 15 of the hopper and opens the inlet 32 and outlet 33 of the tank which then supplies the engine. Reference has been directed by the Comptroller to Specifications 712,085 and 736,335, [Group XXXIV].

Abstract: 1510493 Rotary compressors with cooling and sealing liquid flow control HOKUETSU KOGYO CO Ltd 15 Aug 1975 [2 Sept 1974] 34121/75 Heading F1N Liquid mixed with the gas delivered by a liquid cooled rotary compressor is separated immediately on its discharge to a chamber 10, the separated liquid being delivered by a pressure drainage pump 15 to a compressed gas receiving tank 17 for subsequent injection through a nozzle 25 into the working chamber(s) 1 at a rate determined by a regulator 24. The compressor is of the vane, screw, worm, centrifugal or turbine types. A pump 22 or the pressure in the tank 17 forces the liquid collected in the tank 17 through a cooler 20 and the regulator 24 to the nozzle 25. During full or partial unloading of the compressor a valve 7 is moved to throttle or stop the flow of gas entering the compressor through an intake opening 6. The resulting reduction in the delivery pressure causes a check-valve 11 to close. In order to reduce the power consumption during unloading the supply of liquid to the nozzle 25 is reduced by the regulator 24, a piston 37 thereof being movable by the valve 7 to a position restricting the flow area through the regulator. Gas in the tank 17  flows through a separator 27, a line 28 and a valve 29 to a point of use. The nozzle 25 may be located in a slide valve (34), Fig. 5 (not shown) movable by fluid-pressure to change the outlet flow area of the compressor.
