Title: Improvements in or relating to gripping devices
IPC: B25B5/06
Filed: 1959-08-21
Abstract: 880,162. Work-holders. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 21, 1959 [Aug. 30, 1958], No. 28638/59. Class 83 (3). A work-holder comprises horizontal and vertical supports 1, 5, to which the work 2 is clamped by clamps 3, 6, simultaneously actuated by a fluid-operated piston 19, and simultaneously rotated about axes B, B, A, A, to inoperative positions, by a fluid-actuated rack 29, after being withdrawn to release the work. The jaw 6 is secured to a sleeve 9 having two bushes 13, 14 therein, urged apart by a spring 15, the distance between the flanges 13a, 14a of the bushes being adjustable by nuts 16a, 16b, screwed on to the bush 13. A rod 11 screwed into the bush 13 is connected to the piston-rod 18 of the piston 19, and on the piston-rod is a member 23, which engages one end of a bellcrank 26, the other end co-operating with a bush 25 splined on a shaft 8 carrying the jaw 3. The piston-rod 28 of a second fluid-actuated piston 36 carries the rack 29 which engages a pinion 30 on the shaft 8 to rotate the jaw 3, and also through bevel gears 31, 32, the jaw 6, to their inoperative positions. In operation, buttons 4a, 4b on the jaws 3, 6 are adjusted, and the bush 13 is adjusted on the rod 11 and locked by a screw 12, the distances from the work to the buttons being equal. The piston 19 is moved to the left, and due to the ratio of the lengths of the legs of the lever 26, the clamp 6 will engage the work before the clamp 3. The piston is moved until both clamps secure the work against the supports 1, 5, the pressure being greater on the clamp 3 due to the above ratio. After the work is machined, the piston 19 is moved to its original position, thus releasing the work. The piston 36 is then actuated to move the rack 29 to the right, and the jaw 3 is thereby rotated to a position away from the work. Simultaneously, the bevelgear 31 rotates the gear 32 keyed to the sleeve 9 and the jaw 6 is rotated.

Abstract: 1,118,404. Ice making. GENERAL FOODS CORP. 7 July, 1965, No. 28860/65. Heading F4H. Carbonated ice is produced by mixing water or water ice with an excess of liquid carbon dioxide in a closed reaction vessel and venting the vapour space above the mixture during and following at least the latter part of the reaction period at a constant rate so chosen as to maintain by evaporation of carbon dioxide a temperature of approximately 11 ‹C. and a pressure of approximately 655 p.s.i.g. while the reaction is proceeding. Venting occurs through a valve which is controlled to maintain the constant venting rate, and completion of the reaction is indicated by a fall in the temperature and pressure, after which the carbonated ice product is withdrawn. The ice or water and the liquid carbon dioxide may be introduced into the vessel at such temperatures and in such quantities that the temperature and pressure develop to 11‹ C. and 655 p.s.i.g. during the course of the reaction. Venting is commenced when this temperature and pressure are reached. The carbonated ice produced by the above process contains between 25 and 125 ml. of carbon dioxide per gram of ice. The process may be conducted continuously.

Title: Improvements in and relating to titanium carbide composite material
IPC: C22C32/00
Filed: 1951-12-11
Abstract: In a method of making articles which are permanently resistant to mechanical and chemical stresses at high temperatures by infiltrating a porous body of refractory metal carbide with a metallic material, the porous body or skeleton is produced from a mixture of free-carbon containing titanium carbide powder and chromium powder in which mixture the major portions of the chromium and carbon are present as a solid solution of chromium carbide and titanium carbide and before compacting and sintering to form the skeleton, the particles of the mixture are coated with a metallic binder comprising cobalt nickel, iron or their alloys. In one example a powder mixture comprising carbide powder comprising 75.96 per cent. titan-carbide powder comprising 75.96 per cent. titanium 18.0 per cent. combined carbon and 2.53 per cent. free carbon, all of 325 mesh was placed in a graphite crucible and heated in dry hydrogen for 30 minutes at 2300 DEG C. and the agglomerated mass thus formed was crushed to pass a 140 mesh screen Ten per cent. by weight of carbonyl nickel powder was added as a binder and the mixture treated in a ball mill for 24 hours. The mixture was then hot-pressed to the required shape at 1650 DEG C. and sintered for one hour at 1500 DEG C. in dry hydrogen and finally infiltrated at 1530 DEG C. with a nickel chromium-iron alloy known under the Registered Trade Mark "Nichrome."  In another example, the binder was cobalt powder and the infiltrant was a cobalt-chromium-molybdenum alloy.  The amount of chromium powder added to the original mixture may be increased to 15 per cent.

Title: Improvements in or relating to microwave filters
IPC: H01P1/207
Filed: 1960-08-22
Abstract: 979,768. Waveguide filters. GENERAL ELECTRIC CO. Ltd., and L. D. TEBBENHAM. Sept. 18, 1961 [Aug. 22, 1960], No. 29037/60. Heading H1W. The cavities of a multiple-cavity waveguide filter are tuned by capacitive elements extending into the cavities at right-angles to the direction of propagation, the dimensions and materials of the elements and their supports being selected to provide a temperature-dependent degree of penetration of the elements whereby changes in dimensions of the cavities with temperature are compensated. As shown, a waveguide cavity 1, made of brass, is tuned by means of a screw 4 made of " Invar " (Registered Trade Mark). The screw is surrounded by conductors 5, 6, made respectively of brass and aluminium, which together with the screw form a half-wavelength coaxial line whereby the short-circuit formed by plate 7 is transferred to the wall of the cavity. The cavities are bounded by shunt susceptances in the form of rows of transverse conductive posts connecting the broad walls of the waveguide. The susceptances are graded to impart desired band-pass characteristics to the filter. The Specification contains a detailed mathematical analysis of the invention.

Title: Remote-control system for starting and stopping diesel engines
IPC: H02P9/08
Filed: 1954-10-08
Abstract: 784,583. Starting and stopping. BROGAN, D. W. Oct. 6, 1955 [Oct. 8, 1954], No. 29113/54. Class 7(5) [Also in Group XXXV] A remote control system for starting and stopping a diesel engine includes a first solenoid 2 which for stopping moves a fuel control lever 7 against a spring 8 to the stop position, in which it is held by an interlocking device 6, and a second solenoid 1 which at starting trips the device 6 to allow the lever 7 to be moved by the spring 8 to the supply position, the solenoids being controlled by a relay device 12 operated by the battery charging generator 11 so that if a control switch 18 is closed when the engine is running, the solenoid 1 remains inoperative whilst the solenoid 2 is energized to cut off the fuel and stop the engine. The relay device 12 is combined with the battery charging cut out and includes contacts 14, 15 in the battery charging circuit and the circuit of solenoid 2 respectively which are open when the engine is stopped and closed when it is running, and contacts 16 in the in the circuit of solenoid 1 which are closed when the engine is stopped and open when it is running. A solenoid-operated starting motor switch 10 is wired in parallel with the solenoid 1, which latter solenoid operates a decompressing mechanism 3 in addition to the interlocking mechanism 6. To start the engine a button 18 is depressed which, due to the contacts 16 being closed, completes the circuit of the switch 10 to operate the starting motor 9 and energises the solenoid 1 to operate the decompressing mechanism 3 and trip the mechanism 6 to allow the lever 7 to move to the fuel supply position. The solenoid 2 remains inoperative as contacts 15 are open. After a short period the switch 18 is released which de-energizes the solenoid 1, rendering the decompressing mechanism inoperative. The engine continues turning at full compression under its own momentum and fires. When running, the battery cut-out solenoid 17 operates to break the contacts 16 and close the charging contacts 14 and the contacts 15 in the circuit of solenoid 2. To stop the engine the button 18 is depressed whereby, due to the closed contacts 15, the solenoid 2 is energized to move lever 7 to the stop position in which it is held by the interlocking mechanism 6, the solenoid 1 and starter motor switch 10 remaining inoperative due to the contacts 16 being open. The solenoids 1, 2 may be arranged in a box adapted to be mounted as a unit on the engine. In a modification the solenoid 1 is arranged in series with the starter motor 9 and the mechanism 6 is tripped by a separate solenoid in parallel with the switch 10. For very cold starting, contacts 22 in the solenoid circuit 1 are opened by a relay 22 when the speed of the engine being turned over by motor 9 is just below starting speed, whereby the decompression device 3 is put out of action and the engine is turned over by the motor 9 at full compression until it fires. The relay 22 is connected directly to the generator 11.
