Title: Improvements in and relating to magnetic cores
IPC: H01F41/02
Filed: 1947-12-02
Abstract: 645,277. Electrolytic polishing. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 2, 1947, No. 31832. Convention date, Oct. 11, 1945. [Class 41] In a method of electrolytically polishing a face of a laminated magnetic core part by immersing the face in an electrolyte and making that face the anode in an electrolytic process, the positive potential is applied to the core part at a place other than the face to be polished, by means of a dry solid conducting member which is arranged to contact the edges of all the laminations simultaneously and is adapted to conform to irregularities therein. As shown in Fig. 2. a face of the core is engaged by sharp-pointed wire bristles 9 of a metal brush 10, the bristles being connected through a metal plate to the positive side of a source of direct current. An electrode 4 immersed in the electrolyte is connected to the negative lead 5. In modifications a pad of metal wool or a soft lead pad is'pressed against the core face. In a further arrangement, shown in Fig. 5, a core pad 16 has all of its laminations on one side connected together by an arc weld 17 so that both end faces of the core, which are immersed in the electrolyte, can be polished simultaneously. Specification 601,980 is referred to.

Title: Device for producing a gas or vapour stream for spraying strips coated in molten metal
IPC: C23C2/20
Filed: 1975-07-30
Abstract: 1500060 Nozzles ITALSIDER SpA 30 July 1975 [8 Aug 1974] 31873/75 Heading B2F Apparatus for producing a stream of gas or vapour, for example for spraying a metal strip being withdrawn from a bath of molten metal with a jet of steam or air, comprises an elongated nozzle formed by two lips 2, 3 inclined towards each other, a pair of sliding shutters 5, one of which is shown in Fig. 5, for adjusting the nozzle length, and a conduit 7 for supplying gas or vapour to an outlet at the inner end of each shutter immediately adjacent the unshielded part of the nozzle outlet. The lips 2, 3 are connected to a manifold 1; lip 2 is rigid but lip 3 is resilient owing to the presence of a slot 4, and the position of this lip can be adjusted to vary the width of the nozzle outlet. The conduit 7, which is preferably elongated in the direction of the manifold axis, is connected between a chamber 6 in the shutter and a sleeve 8 sliding inside a second conduit 9 parallel to the nozzle lips, gas or vapour being fed into this second conduit by feeding means shown in Fig. 4. The transverse profile of the shutter matches the inner profile of the cross-section of the nozzle and the rear part of the shutter engages in a groove 10 in the manifold. The length of the nozzle may be varied by moving the conduits 7 and associated shutters manually or automatically by control means sensing the width of the strip to be coated. In use, gas or vapour is fed under pressure to the central area of the manifold 1, and gas or vapour is fed through conduit 7 at a pressure higher than that of the gas or vapour fed to the manifold, thereby producing streams of gas or vapour at higher pressure at the ends of the nozzle.

Title: Improvements relating to resilient couplings
IPC: F16D3/72
Filed: 1931-11-17
Abstract: 389,907. Universal joints. FRASER, R. P., 20, Margravine Gardens, Baron's Court, London. Nov. 17, 1931, Nos. 31892/31 and 704/32. [Class 80 (ii).] A torque-sensitive resilient coupling comprises a circularly disposed group of resiliently deformable strips extending in outwardly peaked form between annular end-members, whereby both relative torsional movement and relative angular movement are permitted between the end-members. The coupling may be formed from a sheet of metal, Fig. 1, provided with end-portions 1 connected by intermediate strips 2 and peaked at 3 so that when the sheet is rolled into cylindrical form and compressed longitudinally, Fig. 3, the strips 2 are outwardly peaked into a spring-bow shape. The strips may be arranged helically between the end members, being formed from the blank shown in Fig. 5, or held in position separately by collars 7, Fig. 6. The strips may be stiffened near their ends with additional leaves. They may be loaded at their centres so as to be sensitive to centrifugal force, one of the end members 1 being splined on its shaft. To prevent the strips from tearing away from the end-members, the slits between them may have circular ends and be tapered away from the ends. Reduction in diameter under torque may be limited by a ring, cage, or ball within the strips or by outwardly flared members 6 which simultaneously shorten the effective length of the strips as the torque increases. Also, the outward deflection near the ends of the strips may be limited by a sleeve, band or flared tube (not shown). The strip portions 2 may be of different lengths on opposite sides of the peaks, those on the driving side being preferably shorter. For heavy work, each spring may be in two parts with spring-bow connecting- pieces. For very light couplings, the strips may be of shellaced paper, for heavier couplings of rubber or the like, and for heavy work of sheet steel.

Title: Improvements relating to gas pressure regulators
IPC: G05D16/06
Filed: 1930-10-23
Abstract: 366,111. Pressure-regulating valves. GAWA-PATENTVERWALTUNGS AKT.- GES., Schaffhausen, Switzerland. Oct. 23, 1930, No. 31900. Convention date, Oct. 23, 1929. [Class 135.] Means for regulating the pressure of a combustible gas comprises a regulating valve f carried by a diaphragm c subjected on its upper side to atmospheric pressure in a chamber B, whilst coaxially with the valve on the outlet side there is provided on the valve a nozzle #1 through which the whole of the regulated gas passes, the space C below the diaphragm c being connected to the nozzle at its narrowest point through an annular gap o. The kinetic energy of the gas in the nozzle produces a reduction in pressure in the chamber C which depends on the gas consumption, increased demand causing an increased valve opening. The annular gap o has a similar pressure reducing effect, being of variable width depending on the valve opening. The valve is also supported by a second diaphragm i subject on its upper side to inlet pressure of the gas which passes from a side supply-pipe a into a cylinder Z through an apertured impinging plate Z2 into a sieve Z1 and thence to the adjustable valve seat g.

Filed: 1949-12-15
Abstract: 672,308. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 15, 1949 [Dec. 29, 1948], No. 32218/49. Class 29 In a refrigerating system having two evaporators 2, 3 operating at different temperatures and selectively supplied with refrigerant by a valve 11, means such as a fan 36 is provided for circulating air only over the higher temperature evaporator 3 when either evaporator is being refrigerated. The fan may be driven by the circulating refrigerant or by an electric motor energized during the operation of the condensing apparatus 1. The evaporators are supplied with refrigerant in parallel from the condenser 4 through a pipe 6, and the valve 11 is controlled by a magnet 12 in the valve casing 14 cooperating with a magnet 13 outside the casing the position of which is adjusted by a bellows 17 connected to a thermostatic bulb 15 in the food compartment cooled by the higher temperature evaporator 3. In the position shown, corresponding to a high temperature in the food compartment, the magnet 13 attracts the magnet 12 closing port 9 and opening port 10 so that refrigerant is supplied through capillary pipe 20 to the high temperature evaporator 3. When the temperature of the food compartment falls to the required value the bellows 17 moves the poles of the magnet 13 away from those of the magnet 12 and the valve 11 drops, closing port 10 and opening port 9 to supply the refrigerant to the low temperature evaporator 2 only. Liquid refrigerant from the condenser 4 passes through a capillary tube 35 in contact with the suction line 23 to a third evaporator 38 and thence to a turbine 37 driving the fan 36 circulating the air of the food chamber over the evaportors 38, 3. When refrigerant is being supplied to the low temperature evaporator 2 the air circulated by the fan 36 serves to defrost the high temperature evaporator 3. The compressor motor is controlled by a thermostat 27 and bellows 29 operating a switch 30. In a modification the fan is driven by an electric motor connected to a switch operated by the bellows 29 and the valve 11 is actuated by an electromagnet. The chamber 39 of the valve forms a store of refrigerant for starting refrigeration in the evaporator 3.
