Abstract: 850,604. Machine-tool details. REGIE NATIONALE DES USINES RENAULT. June 28, 1957 [July 6, 1956], No. 20568/57. Class 83 (3). [Also in Group XXX] A device for transferring a workpiece P from one station to another comprises means 9 for moving the workpiece horizontally to an intermediate station, means 4 for lifting and rotating the workpiece about a vertical axis, and means for depositing the workpiece at the final station. A cylinder-block P is delivered from one machine-tool by a turret device 3, to a gripping means 9, reeprocated by a fluid-pressure jack 10 driving, through a rack-and-pinion 12, an eccentric 13, a connecting-rod 14, and an oscillating link 17. The gripping means includes two arms 26 which can be swung outwardly to engage bores 33 in the block P, which rests on rails 34. The block may be lifted by a device 4 having four supporting-dogs 38 on rods 35 which can be rotated simultaneously by an hydraulic ram 43 acting through a linkage. A spring-pressed cam 44 on the device urges the block laterally against a locating-pad 48. A further such cam urges the block longitudinally against another locating-pad. Spring-pressed plates 51 urge the block against the dogs 38. Cams 53, 54, on two of the rods 35 actuate switches to control the degree of rotation of the rods. The lifting-device 4 is mounted on a slide 65, which can be moved along rods 66 by a screw 67 rotated by a motor 68. The device can furthermore be swung about a pivot 61 by a projecting rod 62 engaging fixed rods 63, 64, and can also be moved vertically by rack-andpinion gearing rotated by a motor 75 through a shaft 71. In operation, a block is delivered from one machine-tool and rotated by 180 degrees about a horizontal axis by the turret device 3. The gripping-means are advanced to grip the block and then retracted, drawing the block to the left until fixed stops 31 engage rollers 28 on the arms 26, causing the block to be released. The lifting-device is then lowered, the dogs 38 rotated, and the block lifted. When the block has been raised, the slide 65 is traversed to the left, the block being rotated about a vertical axis as the arm 62 encounters the rods 63, 64. When the block is directly above a work-holding pallet M, it is lowered and deposited thereon, ready to enter a further machine-tool.

Filed: 1952-08-15
Abstract: 699,613. Refrigerating. SERVEL, Inc. Aug. 15, 1952, No. 20589/52. Class 29. In a continuous cycle absorption refrigerating system operating at a pressure less than atmospheric wherein absorbent is raised from a heated generator 5 through a pipe 6 to a separator chamber 7 for the absorbent and the gaseous refrigerant by the gaseous refrigerant expelled in the generator 5, the rate of generation of refrigerant vapour, the cross-section of pipe 6 and the lead h of pressure between the liquid levels in the generator and in a reservoir 31 are so correlated that the absorbent is conveyed in droplets up the pipe 6 by gaseous refrigerant in continuous phase and that a desired ratio of liquid circulated to refrigerant generated is attained. As shown in Fig. 1, the entraining of absorbent by gaseous refrigerant results from the gas picking up foaming absorbent from the surface of the liquid in generator 5. As shown in Fig. 3, gaseous refrigerant and absorbent pass from generator 43 through pipes 44, 45, the latter of which discharges upwardly into the bottom of pipe 40 leading to the separator 42 so that the absorbent is dispersed in the ascending refrigerant stream. Non-condensible gases are withdrawn from absorber 19 by a purging device 34, a storage vessel 35 and a pump.

Title: Improvements in absorption refrigerating apparatus
IPC: F25B17/00
Filed: 1932-07-23
Abstract: 399,953. Refrigerating. DREVET, E., 7735, St. Denis Street, Montreal, Canada. July 23, 1932, No. 20852. [Class 29.] Absorption machines and systems.-The flow of refrigerant liquid from the air-cooled condenser coil 14 to the reservoir 23 of a reversing machine is controlled by a spring-loaded valve 20 arranged in a chamber 16 and adapted to close the open end of the condenser outlet pipe 15. When the pressure in the coil exceeds a predetermined value the valve is displaced from the end of the pipe and the condensate flows through the pipe 22 to the reservoir which is secured to the pipe 22 so that it rises and falls according to the weight of liquid refrigerant therein. In the generating position shown, the refrigerant vapour, e.g. ammonia, flows from the generatorabsorber 5 through the pipe 8 extending through the rectifier 12 to the water-cooled condenser coil 9 from which the condensate passes into the rectifier wherein the refrigerant is vaporised and passes on to the air-cooled coil 14, while solvent liquid, e.g. water, returns to the generator-absorber through the pipes 17, 18. Current is supplied to the electric heater 6 of the generatorabsorber through a circuit comprising a main 38, including a switch 37 controlled by a thermostat in the refrigerator containing the evaporator coil 36 which is supplied through an expansion valve 35, and a branch main between the sections 45, 46 of which is a snap-action spring switch 28, 29. When the liquid level in the reservoir reaches a prearranged height, the reservoir falls and displaces the spring 28 of the switch thus breaking the circuit through the branch main and completing that through the mains 38, 44 to a solenoid 43 which opens a valve 42 in a thermo-siphonically acting cooling water system for the generator-absorber. This system comprises cooling coils 41 in the generator-absorber and an air-cooled radiator 40. In the event of the pressure in the machine rising unduly a diaphragm in a chamber 48 fractures and permits flooding of the machine from the cooling water system..

Title: Improvements in electrical protective gear for alternating current systems
Inventor: RYDER CLIFFORD
IPC: H02H3/30
Filed: 1950-08-23
Abstract: 699,638. Protective cut-out systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 10, 1951 [Aug. 23, 1950], No. 20890/50. Class 38 (v) In a balanced-voltage protective system, the relay at each end of the protected section is of the moving- coil polarised type and has an operating coil 10 connected through a rectifier 11 in series in the pilot circuit 8, 9 for response to unbalanced conditions in the pilot circuit and a retaining coil 12 connected through a rectifier 13 in parallel with the pilot circuit for energisaton in accordance with the voltage applied to the associated end of the pilot circuit. In Fig. 1 which shows one end of the system, a single pilot circuit is used, the outputs of current transformers 4-6 being summated by a transformer 7 for application to the pilot circuit. Alternatively, Fig. 2 (not shown) a relay may be associated with each phase, independent auxiliary current transformers and pilot circuits being used. Under normal conditions or under through fault conditions the voltages applied at the ends of the pilot circuit or of each pilot circuit are opposed and substantially equal and substantially no out-of-balance current flows through the relay operating coils 10, whilst the restraining coils 12 are fully energised. Under internal fault conditions, the out-of-balance currents in the pilot circuit or circuits energise the coil 10 to open the relays against the restraining bias of the coils 12. A non-linear resistance 15 may be connected across each summation or auxiliary transformer to limit the voltage applied to the pilot circuit or circuits. In Fig. 3, a smoothing circuit comprising an inductance 20 and a capacitance 21 may be connected across each summation transformer 7 to eliminate harmonics, the pilot wires 8, 9 being connected across the capacitance 21. As an alternative to, or in addition to the non-linear resistance 15, a non-linear resistance 22 may be connected across each capacitance 21. A load responsive relay may have its operating coil 27 connected through a rectifier 28 in each smoothing circuit, the relay when operated under fault conditions, opening its normally closed contacts 29 to remove a short circuit from the operating coil 10. To check the continuity of the pilot circuit, a battery 23 and. the coil 26 of an alarm or supervisory relay are connected across an inductance 24 and capacitance 25 which are in the pilot circuit and tuned to the system frequency. So long as the pilot circuit is complete, D.C. circulates and the coil 26 remains energised. At the other end of the pilot circuit a similar alarm or supervisory relay may have its coil connected across an inductance and a capacity in series in the pilot circuit. This relay may be polarised so that it operates not only upon interruption of the pilot circuit, but also in the event of the pilot wires becoming crossed. Specifications 686,477 and 694,785 are referred to.

Abstract: 424,770. Automatic electromagnetic regulators. STONE & CO., Ltd., J., Deptford, London, BROWN, A. J. S., 44, Tweedy Road, Bromley, Kent, and ASH, A. L., Inglenook, Acacia Drive, Thorpe Bay. July 28, 1933, No. 21288. [Class 38 (iv)] A carbon pile regulating arrangement for battery charging installations &c. is provided with two separate magnet systems for control over two or more stages of the regulation. The magnet systems employed are of the types described in Specifications 414,111 and 414,122, and comprise magnets 21, 22 carrying windings 3<1>, 3<2>, rotors 7<1>, 7<2> on spindles 61, 62 and springs 32<1>, 32<2> connected to discs 161, 16<2> and controlling the motion of the rotors. The movement of the discs 16<1>, 16<2> is damped by dash pots 37 and limited by stops 39, 40. The carbon pile 21 is connected through a compression plate 20 and push rod 19 to a crank 17 which is mounted on a separate spindle 74. A tension spring 75 is connected to a lever 73 and maintains the pile under compression. Fingers 761, 76<2> mounted on the discs 161, 16<2> extend underneath the end of the lever 73 which they engage by adjustable abutments 78. Upon charging a battery, at the commencement the latter takes a relatively large current at small voltage. This causes the rotor 71 to bring the finger 76<1> into contact with the lever 73 and thereby regulate the current output of the dynamo. As charging proceeds the charging voltage rises and eventually reaches a value at which the rotor 7<2> is attracted. The finger 76<2> then overtakes the lever 73 and assists the finger 76<1>. This however causes a decrease in the charging current and the finger 761 falls away so that the charging proceeds solely under voltage control. Adjustments of the carbon pile and spring systems are effected by turn screws 27, 36 respectively. The current controlled unit may also carrying on winding 3, a small number of turns excited proportionally to battery voltage to increase the initial charging current.
