Title: Improvements relating to fluid pressure control valves
Inventor: CROASDAILE FREDERICK GEORGE
IPC: G05D16/06
Filed: 1959-05-11
Abstract: 943,549. Valves. OXYGENAIRE (LONDON) Ltd. April 27, 1960 [May 11, 1959], No. 16083/59. Heading F2V. A fluid pressure control valve comprises a valve body 1 having its interior divided into two chambers 15, 16 by a diaphragm 10, an outlet 8 communicating with the chamber 15, a tubular member 6 clamped to the diaphragm, the bore 9 of the member providing an inlet into the chamber 15, a movable needle valve 18 carried by supporting means 19 connected to the diaphragm, movement of the needle valve in one direction being effected by pressure fluid entering the inlet opening of the valve and, in the opposite direction, by pressure fluid acting on the diaphragm. The diaphragm 10, which may be of a synthetic plastic material, is clamped between a housing 1 and a nut 4, thereby defining the pressure chamber 15 and the second chamber 16 open to atmosphere through a port 17. The needle valve 18 is screwed into a yoke 19 and may be provided with a screwdriver slot to effect adjustment thereof. A second closure member 21 is provided and may be formed integrally with the needle valve; both valves may be of a synthetic plastic material. In operation, fluid enters an inlet 9 and passes into the chamber 15, the pressure then acting on the diaphragm and thereby tends to balance the valve against the inlet pressure. If excessive pressure builds up in the chamber 15 due to increase in supply pressure, the valve member 21 is forced against the outlet opening 8 until the inlet pressure is restored to normal.

Title: Improvements in or relating to fluid jack or like devices
IPC: F15B15/26
Filed: 1941-12-15
Abstract: 577,947. Hydraulic machines. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. Dec. 15, 1941, No. 16181. [Class 69 (ii)] [Also in Group XXVIII] Fluid pressure jacks for use on aircraft for operating flaps, bomb doors, retractable undercarriages, &c. are locked in extended or retracted positions by means of locking-devices mounted externally of the cylinder and operable by fluid pressure to release the locking device. As shown in Figs. 1 and 2, a hollow ram 14 is mounted in a cylinder 10 provided with heads 12, 13 with inlets for fluid pressure. The ram 14 is fitted with a pin 21 which is engaged by a spring-controlled locking device in the form of a pivoted half-sleeve 19 having a notch 20 for engaging the pin in the retracted position of the ram 14. The ram is moved to this position by fluid admitted to the head 13 acting upon a piston 33 to which the ram is connected by a pin 31 and slot 32. Within the ram is a rod 30 secured to the piston, and a pin 28 on this rod moves a cam 27 free of a pin 25 of the catch when the ram is fully withdrawn and permits the locking-device to engage the pin 21. When pressure is applied to the cylinder head 12 the ram cannot move until the piston 33 moves to the right and causes the cam 27 to free the locking-device, so that the device remains locked until fluid pressure is applied. In a modification, Fig. 5, a hollow ram 40 provided with a piston 42 co-operates with a cylinder 41 and toggle links 50, 51 are used to connect a sleeve 45 on the cylinder 41 with a cross-head 48 connected to the ram. When the jack,is extended to the position shown in Fig. 5, the toggles move so as to be past the dead-centre position and springs 52 maintain them in this position so that pressure on the piston 42 can not move the ram which is held in locked position until the toggle is moved outwards past the dead-centre position by the action of rollers 55 on a sliding sleeve 54 upon cam blocks 53 connected to the links 50. The sleeve 54 is connected by a rod 58 to a piston 59 slidable in the ram 40 and subjected to fluid pressure in the jack. It is necessary for the rollers to break the toggle before the jack can be operated either when it is in the expanded position shown or in the retracted position in which the links 51 are operated to draw the sleeve 45 towards the cross-head 48. In a further modification the locking-device comprises a longitudinally split sleeve having an annular shoulder adapted to engage with a corresponding shoulder for locking purposes, and means for producing radial distortion of the split sleeve for separating the said shoulders and releasing the lock.

Title: An electric motor
IPC: H02K7/16
Filed: 1961-05-05
Abstract: 935,008. Motor driving arrangements. SIEMENS-SCHUCKERTWERKE A.G. May 5, 1961 [May 13, 1960; May 17, 1960], No. 16492/61. Class 35. [Also in Groups XIV and XXXII] A high speed electric motor has a hollow rotor shaft within which is mounted an output shaft which is pivoted at a point within the hollow shaft, oscillation damping means being provided on one side of the pivot and resilient centring means on the other. Fig. 1 shows an electric motor having a rotor 1 mounted on a hollow shaft 2 supported by a pair of bearings 3. Within the shaft is a further shaft 5 for supporting at its upper end a spinning pot for a synthetic filament and which in operation may vibrate. To prevent the vibration being transmitted to the rotor the internal shaft 5 is pivotally supported within the hollow shaft by a bush 13. The upper end of the inner shaft 5 is resiliently centralized by means of a spring 18 supported at each end by the outer shaft and supporting at its central portion the inner shaf through a bush 20. The lower end of the inner shaft projects beyond the outer, and latera oscillatory movement is damped by means of pressure plates 15, 16 urged together by a spring 17. Drive is transmitted from the outer to the inner shaft through three members 6, 7 and 8 shown in more detail in Fig. 2. Part 6 is fast with the outer shaft, part 8 fast to the inner shaft and part 7 is floating and provides a coupling therebetween. In Fig. 3, in which the motor surrounding the upper part is not shown, oscillatory movement of the shaft is prevented by an air or oil damper consisting of closely adjacent hollow cylinders or of a spiral winding 21 located in the oil reservoir 23. Longitudinal oscillation is damped by providing the inner shaft 25 with a stepped lower end located in an oil chamber 27 having a small orifice 28 connecting with the reservoir. The pivot bush 13 of Fig. 1 is replaced by a swelling 13 or by a corresponding swelling on the inside of the outer shaft. In Fig. 4 the oil-type damper is retained, but a resilient coupling is provided between the inner shaft 33 and the output shaft 34. For this purpose the centralizing spring 38 has a non-circular cross-section as shown in Fig. 5 so that it will non-rotatably engage a swelling 41 on the inner shaft and collars 39, 40 provided on the outer shaft. A pin 42 also helps to avoid relative movement between the inner shaft and the central part of the spring.

IPC: C01B21/26
Filed: 1918-10-10
Abstract: 205,856. Partington, J. R. Oct. 10, 1918. Catalytic apparatus; nitrogen oxides, catalytic production of by combustion of ammonia. - In the oxidation of ammonia by passing it in admixture with oxygen or air enriched with oxygen over a catalytic material, steam is added to the gas mixture to render it non-explosive. Ammonia solution is sprayed through a nozzle c in the presence of oxygen or a gas rich in oxygen admitted by a pipe b and becomes evaporated in a heated spiral a, preferably of aluminium and packed with aluminium turnings; the resulting gas mixture passes to a preheater e, consisting of a number of aluminium pipes heated by hot gases; the gas mixture then proceeds to the converter g containing the catalyst, such as heated platinum gauzes; the products are cooled and absorbed in a vessel i, any remaining nitrogen oxides passing by the outlet ! l to an absorption tower. The original gas mixture may be enriched with either oxygen or ammonia by admitting a supply through an inlet pipe between the evaporator and the preheater; alternatively, water may be sprayed or steam admitted into the evaporator and ammonia gas then introduced by the intermediate inlet pipe. Also, a further supply of oxygen may be admitted by a pipe h into the cooler i, if the higher oxides of nitrogen are to be produced.
