Title: An hydraulic percussion tool
IPC: B21J7/24
Filed: 1956-11-20
Abstract: 805,288. Percussive tools. HUPPERT & CO. Ltd., C. Nov. 20, 1956 [Nov. 23, 1955], No. 35488/56. Class 124. A hydraulically operated percussive tool comprising a casing, a cylinder having a piston therein, and a striker operatable by and movable in unison with the piston has at least one pneumatic pressure accumulator coacting with the pressure liquid, a high pressure liquid conduit communicating with the working side of the piston, a second conduit, in which high and low pressure conditions alternate, communicating with the return side of the piston, the pneumatic pressure accumulator being continuously associated with the high pressure conduit and intermittently with the second conduit, the latter being in intermittent communication with a low-pressure return line to conduct pressure liquid from the return side of the piston during the working stroke. As shown, a piston 4 having a striker 5 is acted upon by pressure liquid in a blind cylinder 8 to drive it downwardly and strike the shank of a drill steel 7, rotary valves 18 and 19 driven by a hydraulic motor 20, 21 controlling the supply of pressure liquid to a space 10 (of greater crosssectional area than the cylinder 8) to return the piston. Pneumatic accumulators 13 and 15 are provided in the pressure line and return line respectively to ensure a constant liquid pressure. Starting and stopping the machine is controlled by a valve 27 which when open allows the pressure liquid to circulate and the tool is inoperative. On closing the valve 27 liquid under pressure is supplied to the cylinder 8 and with the valve 18 closing the port 47 and the valve 19 opening the port 25 the space 10 is connected to the return line and the piston moves downwardly in a working stroke. Further rotation of the valves 18 and 19 causes opening of ports 23 and 47 and closing of port 25 thus connecting the pressure liquid to the space 10 and returning the piston. The accumulator 13 is always in contact with high pressure liquid and when the valve 18 is closed is in a compressed condition but when valve 18 opens it expands and a constant pressure is maintained in the liquid. The accumulators comprise flexible containers and are charged to a predetermined pressure, e.g. high pressure accumulator 13 to 450 lbs. per sq. in. and low pressure accumulator 15 to atmospheric pressure when the liquid pressure is 800 lbs. per sq. in. on the high side and 70 lbs. per sq. in. on the low side. A detailed description of a practical embodiment of the invention is given. Figs. 2-8 (not shown).

Title: Attachments for duplicators
IPC: B41L9/08
Filed: 1920-12-17
Abstract: 177,221. Fairweather, W. C., (Beck Duplicator Co.). Dec. 17, 1920. Copying documents.-An attachment for duplicators, of the type provided with a movable adhesive duplicating-medium, comprises a sheetsupporting member having an opening in the bottom, the pile of sheets being depressed towards the duplicating-medium so that a part of the lower sheet adheres thereto and the sheet is withdrawn from the pile, the remainder of the sheets being retained in position upon the supporting-member. As shown in Fig. 1, a duplicating-film is wound upon rollers 13 and passes over a bed on the duplicator frame, the attachment comprising a base 23 having an opening at one end and provided with sides 21 and ends 22, a bracket 24 attached at one end lying flush with the base and extending into the opening in the base. Side pieces 25 support this end of the attachment clear of the duplicating- film. The other end of the attachment is provided with extension pieces 26 having pins 27 engaging slotted members 28 on the frame of the duplicator, the slots being closed by latches 29. This construction provides a hinge joint between the attachment and the duplicator frame. On pressure being applied to the pile over the opening in the base of the attachment, the lower sheet adheres to the duplicating-film and is withdrawn when the attachment swings upwards. A sheet gauge, Fig. 4, has lugs 31 which straddle the sides of the attachment. In another form of attachment, shown in Fig. 5, the sheet-supporting table has depending flanges 43 so that it can slide upon the duplicator frame. The sides 42 project beyond the base 4G and have pivotally mounted between them a U shaped frame 44 provided with a handle 45 and an impression roller 46. The frame 44 has also secured to it a paper-depressing member 51, a laterally extending finger 47, and an adjustable paper-supporting shelf 48. When the pile of papers is depressed towards the duplicating-film, the finger 47 enters a depression 153 in the bed of the duplicator, and when the table is being returned, this finger rides upon the bed to keep the paper-depressing member elevated.

Title: Process for removing higher-melting fatty materials from glyceride oils
IPC: C09F5/00
Filed: 1962-09-21
Abstract: The subsequent removal of higher melting fatty material from glyceride oils is facilitated by the addition of 0.001-0.5%, by weight of the oil, of a sucrose fatty acid ester which contains not more than 5 unesterified hydroxyl groups per sucrose molecule and which contains, by weight of the total fatty acids, 15-80%, C12- 22-saturated acids and 85-20%, C12- 22-unsaturated acids; the fatty acids present in the additive suitably comprise 8-16% palmitic acid and 5-15% stearic acid so as to amount in total to 15-27% saturated acids, and 64-76% octadecenoic acid and 3-9% octadecandienoic acid so as to amount to 85-73% unsaturated acids.  The oil and additive may either be heated together until all the fatty material present is liquid before being cooled, or alternatively, the oil may first be completely liquified by heating and the additive then added.  The preferred sucrose ester contains 19% palmitic and stearic acids, 79.5% oleic acid and 1.4% linoleic acid. Specification 604,136 is referred to.
Patent GB-644992-A (GB)
Title: Improvements in and relating to electron discharge devices
IPC: H01J31/04
Filed: 1946-12-05
Abstract: 644,992. Frequency and phase modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 5, 1946, No. 36063. Convention date, Dec. 5, 1945. [Class 40 (v)] [Also in Group XL (a)] In an electron discharge device (see Group XL (a)) for producing phase and frequency modulation, a planar disc of electrons emanating from a central cathode 39, Fig. 6, has a sinusoidal edge produced by the polyphase energization of a plurality of control electrodes 21<SP>1</SP> arranged in groups on one side of the electron disc opposite a neutral electrode arranged on the other side of the disc. Due to the polyphase energization of the control electrodes, the sinusoidal wave at the edge of the electron disc advances around the disc at the frequency of the polyphase carrier wave. The electrons fall on one or other of two anodes arranged concentric with the cathode in accordance with the progression of the sinusoidal wave at the edge of the disc to produce an output voltage at the polyphase carrier frequency. The inner anode 6, Fig. 5, has openings 51, 52 through which electrons may pass to the outer anode. As shown, the wave 53 represents the edge of the electron disc at the instant when all the electrons pass through the openings 51, 52 and are collected by the outer anode. At the instant represented by the wave 54 all the electrons are collected by the inner anode 6. This voltage is modulated by a modulating magnetic field perpendicular to the plane of the disc to advance or retard the sinusoidal wave at the edge of the disc with respect to its unmodulated position. The anodes may be constructed to provide a three-phase output.

Title: Improvements in brakes
IPC: B64C25/48
Filed: 1933-12-22
Abstract: 427,829. Aircraft wheel - brakes. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F., WRIGHT, J., and TREVASKIS, H., c/o Dunlop Rubber Co., Foleshill, Coventry. Dec. 22, 1933, Nos. 36083/33 and 14408/34. [Class 4] [See also Group XXXIV] In a hydraulic wheel-brake system for aircraft comprising spaced master cylinders attached to a rudder bar whereby the brakes on the two sides of the craft may be simultaneously or separately applied, each master piston has a rounded recess that receives the spherical end of an angularly displaceable piston rod the other end of which is pivoted to a hinged pedal. A valve may be interposed between each master cylinder and the brake to retain the braking pressure when desired. Each master cylinder 1 comprises a casing 15 clamped by studs 16 to the rudder bar 2 and a cylinder proper 4 bolted at 23 to the casing and clamping a flexible diaphragm 10. A pedal 13 pivoted at 14 to the casing 15 carries at 12 a piston rod 11 having a spherical end 6 normally separated as shown from the piston 5 so that there is communication through the passage 7 in the piston between the lower part of the cylinder to which the conduits 26, 27 leading to the brakes are connected, and the upper part of the cylinder which forms a reservoir for the liquid. The piston 5 has a plate 21 which normally abuts against a stop formed by a spring ring 20. Liquid is supplied to the cylinder through a nozzle 43. The rudder bar has at each end also a heel rest 17 by which the rudder bar is turned when steering. Depression of the pedal to apply the brake on that side of the aircraft first causes the end 6 of the piston rod to seat on the piston thus closing the passage 7 before depressing the piston to establish the braking pressure. Interposed between the conduits 26, 27 is a casing 25 comprising a pair of valve bodies 35 each containing a ball-valve 36 engaged by a rod 32, the two rods being attached to a cross-bar 31 connected by a link 30 to an eccentric on a spindle 28 secured to a handlever 29. The valves are normally unseated as shown to connect the conduits 26, 27 but after the brakes have been applied by the pedals, the valves may be seated by turning the lever 29 to an upper position to prevent the return of the liquid and the release of the brakes when the pedals are released. The lever 29 has a roller 40 which runs upon a spring 41 by which it is locked in its two positions. Specifications 351,299 and 379,529, [both in Group XXXIV], are referred to.
