Title: Power supply circuit for an electrical appliance
IPC: H02J9/06
Filed: 1974-02-15
Abstract: 1417828 Emergency supply systems for lifting magnets SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 15 Feb 1974 [16 Feb 1973] 6949/74 Heading H2H An emergency supply system wherein a load 1, which may be a lifting electromagnet, is normally supplied from an A.C. source 6 by way of a bridge rectifier 7, the elements 8, 9, 10 of which are controllable to vary the voltage applied to the load 1, the load being supplied, in the event of a failure of the A.C. source, from a battery 5 by way of a thyristor 12 which becomes conductive substantially instantaneously upon such failure, is provided with means to vary the firing point of the thyristor 12 correspondingly to the variation made in the voltage applied to the load. The variation in the load voltage is effected by variation in the firing points of thyristors 8-10 in the rectifier 7 by way of a phase shifting control device 11 and a selector switch 20. The selector switch 20 is ganged to a further selector switch 21 which switch selectively controls a device 13 by means of which the firing point of the thyristor 12 is controlled. A control device 14 is provided which renders a thyristor 15 conductive when the A.C. supply 6 is restored, conduction of the thyristor 15 rendering the thyristor 12 non-conductive so disconnecting the battery 5 from the load 1. The switches 20, 21 have a device 23 associated therewith which is operative such that after a predetermined time the selector switches are returned to the position of maximum load voltage. A switch 22 may be provided in one of the lines between the switch 21 and the device 13 so that the device 13 may be disabled when that line is selected.

Title: Catalysts for the copolymerisation of olefins
IPC: C08F210/00
Filed: 1962-02-22
Abstract: Olefines are copolymerized using as catalyst the reaction product, soluble in hydrocarbons, of a vanadium compound or complex, itself insoluble in hydrocarbons, and an aluminium alkyl halide, preferably a dialkyl monohalide such as Al(C2H5)2Cl.  Vanadium compounds mentioned are the vanadium salts of organic acids or oxyacids, e.g. vanadium triacetate, tribenzoate, tristearate, glycolate, lactate, salicylate and camphorate.  Vanadium complexes mentioned are the double salts of oxalic and malonic acids, some vanadates of organic bases and some complexes of vanadium trihalides or vanadyl dihalides with hydrochlorides of bases, such as the compound VOCl2.4(C5H5N.HCl.)H2O. Any aluminium alkyl halide having the formula R1R2AlX may be used where R1 and R2 are the same or different hydrocarbon radicals (aliphatic, cycloaliphatic or aromatic) and X is chlorine, fluorine, bromine or iodine.  In an embodiment, aluminium compounds obtained from the addition AlX2R+ 1/2 Y where X is F, Cl, Br or I; R is an organic radical and Y is an electron-donor compound such as an amine, pyridine, hexamethylphosphoramide and dimethylformamide, or a salt of the type NR4X where X is a halogen as above, or an alkali metal chloride, can also be used.  The polymerization may be carried out in a homogeneous phase or a heterogeneous phase such as when the polymer obtained is insoluble or when it is preferable to operate with dilute monomers in aliphatic solvents or when the monomer in the liquid state is used as the solvent.  The olefines that may be copolymerized are ethylene, a -olefines and olefines containing an inner unsaturation (not vinyl unsaturation) such as norbornene, or the above olefines may be copolymerized with diolefines including conjugated diolefines, non-conjugated diolefines, such as pentadiene-1,4, diallyl, and endocyclic diolefines such as dicyclopentadiene.  In the examples, ethylene and propylene and ethylene and butene-1 are copolymerized and among the vanadium components used are ammonium and vanadyl malonate and VCl3.6CH3.CH2OH and the aluminium alkyl halides employed are Al(C4H9)2F, Al(C3H7)2I, AlC2H5.Cl2 and Al(C2H5)2Cl.  In some of the examples AlC2H5Cl2 is used with N N(C2H5)3, NH(C2H5)2, (C2H5)2O, N(C4H9)4Br, S(CH3)3I or NaCl.  The copolymers can be vulcanized, e.g. with dicumyl peroxide, sulphur and carbon black.

Abstract: 669,789. Refrigerating. CARRIER ENGINEERING CO., Ltd. March 22, 1950 [March 31, 1949], No. 7219/50. Class 29. In continuous cycle absorption refrigerating systems of the general type described in Specifications 649,413 and 639,416 in which the flow of solution is controlled by a valve 29 operated by a control 30 in accordance with the temperature of chilled water leaving the evaporator 4 by a pipe 27, the flow of cooling medium for the absorber 3 and the condenser 7 is controlled by a valve 32 operated by a motor in accordance with the saturated temperature corresponding to the condenser pressure and the supply of steam to the generator 6 is controlled by a valve 34 operated by a control 35 in accordance with the temperature of the solution pipe 13, part of the pneumatic supply to the controls is vented in accordance with an increase in load to discontinue the operation. Compressed air is fed to control 30 from a source 50 so that the solution always flows unless the solution pump 8 fails. The pipe 50 also feeds into a threeway solenoid operated valve 51 which, when actuated, joins pipe 50 to pipe 51 supplying air to control the valves 32, 34 and a valve 39 which maintains a store of water in a tank 37 as described in Specification 658,914. If the temperature of the water in pipe 27 rises, a ball 73 breaks a mercury switch 68 to de-energize the valve 51 which vents pipe 52 to the atmosphere thus shutting off the supply of heating and cooling fluid and discharging tank 37 into the solution line 15. The circuit of the solenoid is also broken if the motor for the chilled water pump 26 or the pump 8 or the motor therefor fail. A barometer tube 85 with contacts is also inserted in the solenoid circuit and its contacts maintain the circuit open until the pressure in the absorber 3 is low enough, i.e. until purging is complete. The air supply to control the valves 32, 34 may be byepassed round the valve 51. The control point of control 35 may be modified by a device 36 responsive to the difference in pressure of the controls of valves 29, 32. A starting switch 67 for byepassing the switch 68 is provided.

Abstract: 1,092,343. Refrigerating; congealing liquids. CHEMETRON CORPORATION. Feb. 22, 1965 [March 4, 1964], No. 7591/65. Heading F4H. A refrigeration system includes an evaporator 11, a vessel 31 disposed beneath the evaporator, a conduit 33 connecting the bottom of the evaporator to a point adjacent the bottom of vessel 31, a vent conduit 34 connecting the top of vessel 31 with the vapour space of the evaporator, a valve 35 in conduit 34 and a heating coil in vessel 31, the arrangement being such that refrigerant can be drained from the evaporator to vessel 31 by opening valve 35 and returned from the vessel to the evaporator by closing valve 35 whille heating the refrigerant to cause partial vaporization and increased pressure within the vessel. Evaporator 11 is cylindrical and contains a tube 16 through which a congealable liquid is passed, the tube containing a scraper 25. The heating coil in vessel 31 comprises part of a line 36 which supplies liquid refrigerant to the evaporator via branch lines 37, 38 leading respectively to the top of the evaporator and to nozzles 44, 45 in the bottom of the evaporator. The nozzles are arranged to discharge tangentially with respect to the surface of tube 16 to cause a circulatory motion of the refrigerant surrounding the tube (Figs. 4 and 5, not shown). The refrigerant level is maintained between lower and upper limits by sensors 60, 61, the former being arranged to close a valve 39 in line 37 when the refrigerant has reached the lower level and the latter to close a valve 40 in line 38 when the refrigerant has reached the upper level. Vapour is withdrawn from the evaporator via a separator 46, which contains semi-cylindrical gauge strips (Figs. 6 and 7, not shown), and a suction line 47 containing a pressure-responsive valve 49, is compressed in a compressor 48 and condensed in condenser 54. In operation, should the congealed liquid become too viscous, as sensed by an overload device connected to the motor driving the shaft of scraper 25, valve 35 is automatically opened and a valve 41 in line 36 is closed to terminate refrigeration. A valve 52<SP>1</SP> may then be opened manually to supply hot vapour from the compressor to the evaporator. Vessel 31 is provided with a pump 64 for collecting contaminants such as oil which may be removed through a valve's conduit 65.
