Abstract: 569,206. Induction motors ; electromagnetic couplings. ENGLISH ELECTRIC CO., Ltd., and AYRES, W. E. M. Aug. 31, 1943, No. ]4188. [Class 35] [Also in Groups XIX and XXXIV] An induction motor, slip coupling, electromagnetic brake or dynamometer has a secondary with a core built up at least in part by assembling a number of separate longitudinal tubes partly or wholly of magnetic material through which cooling fluid can pass. In the form shown, tubes 2 of magnetic material are disposed side by side around the periphery of the unlaminated yoke 1 and are so interconnected by ducts 9 that fluid passes in zigzag fashion around the circumference of the secondary. The tubes may be electrically connected at their ends but insulated along their lengths to form a cage winding with or without other conductors of better conductivity which may be separate or constituted by a sheath on the magnetic material. If air cooling is used, e.g. if the secondary rotates, the tubes can be open to the atmosphere at both ends. Specifications 266,780, [Class 35], 551,414 and 564,665 are referred to.

Title: Improvements relating to regulating means for electrical circuits
IPC: H02M7/06
Filed: 1938-05-12
Abstract: 515,207. Rectifying A.C.; phase changing; automatic regulation. HARMER, H. M. May 12, 1938, No. 14211. [Classes 38 (ii) and 38 (iv)] A load 6 is supplied through two full wave rectifiers 5, one being fed from supply terminals Vs direct or through a transformer or autotransformer; and the other through a circuit comprising a constant inductance 1 in series with a second inductance 2 in parallel with a capacity 4. The inductance 2 at voltages across it not exceeding that corresponding to the "knee-point" of its core magnetization (preferably one with a supply voltage), has a reactance numerically greater than that of the capacity 4 (so that a slight rise of this voltage causes an abrupt fall in its resistance) and the reactance of the inductance 1 is numerically equal to the reciprocal of the sum of the reciprocals of the inductances 2 and capacity 4. The inductance 2 may be substantially equal numerically to the resistance of the maximum load. This arrangement, at full load. gives substantially a two phase rectified supply to the load. The supply given by transformer 3 may be obtained from secondary windings on inductances 1 and 2 connected in series. Three phases may be derived from the arrangement by a Scott connected winding on transformers 2 and 3, or others without the transformer 3. The third harmonic may be suppressed by connecting an inductance in series with the condenser 4 to make this branch resonant to the said harmonic. The condenser 4 may in all cases be transformer coupled. Any type of rectifier may be used.

Abstract: 1,098,297. Measuring systems. R. E. MARTIN. April 5, 1965 [April 7, 1964], No. 14356/64. Heading G4H. A variable is sampled periodically to determine in which range its instantaneous value lies, and a corresponding counter is actuated. The range determination may be by a set of threshold devices or by means of a meter having a pointer which sweeps over a set of contacts. Each counter may comprise a tube into which a ball is dropped whenever a sample lies in the associated range. The tubes display a histogram of the samples, and this may be restricted to the past hour's samples by providing a delay device for removing a ball from a tube one hour after a ball was dropped into it. A similar, all electronic system is described. The stored display may be decreased in an exponential fashion so that more weight is given to recent samples.

Title: Improvements in or relating to rope conveyors
IPC: B65G17/48
Filed: 1958-07-05
Abstract: 873,921. Rope grips. SHIELDS, H. F. H., and DRAG SCRAPER & CONVEYOR CO. Ltd. Oct. 5, 1959 [July 5, 1958; Aug. 11, 1958], Nos. 14376/58 and 25754/58. Class 78(2). The rope grip 12 (Fig. 2) is tightened over the sleeve 11 secured to moving rope 10 by means of nut 22, the nut working on extension 21 of the grip, which extension is threaded. The grip is provided with wheel 24 and carries rotatable sleeve 15, which sleeve carries load carrier 18 on a pivot extending parallel to the rope 10, thus the load carrier is suspended by a form of universal joint. The rope is normally supported by pulley 27. To get round a bend in the horizontal plane the wheel support 29 is curved upwards so that the grip tips over and can pass around a guiding pulley 31 (not shown) with carrier 18 engaging laterally the pulley. Rope grip 52 (Fig. 5), which is driven by collars 55 (not shown) fixed on ropes 43 supported by pulleys 63, 64, is carried by rollers 70 and is connected by pivot 51 to member 60 which is pivoted to load carrier 61. The grip 52 may therefore be twisted through 90 degrees to engage pulley 67 (not shown) and pass round it in the horizontal plane. Alternatively, the chain 50 may be connected directly to grip 52.

Title: A regulating device for hydraulic circuits, such as dan drives
IPC: F01P7/04
Filed: 1969-03-19
Abstract: 1,249,235. Hydrostatic transmission. M. BEHR, [trading as SUDDEUTSCHE KUHLERFABRIK JULIUS FR. BEHR]. 19 March, 1969 [20 March, 1968], No. 14398/69. Addition to 1,186,401. Heading F2D. In a hydrostatic drive for a vehicle engine cooling fan comprising a pump (1), Fig. la (not shown), and a motor (2), a pressure limiting valve 6 is arranged to by-pass motor (2), the response pressure of the valve 6 being automatically adjusted by motor return pressure 19 and the return pressure being delivered via a restrictor 42 to a chamber 40 to load a piston 35 acting on a pilot valve 38 controlling throughflow of an orifice 14 in the pressure-limiting valve piston 13, the chamber 40 being vented through a thermostatically controlled pilot valve 28. As shown, the pilot valve 28 is closed by a thermostat 3 when the temperature exceeds a predetermined value. Below this value, the valve 28 opens to vent chamber 40 to unload piston 35 and open valve 38 allowing flow through orifice 14. Such flow forms a pressure differential across the piston 13 to move the piston down and directly connect delivery and return lines 11, 19, and the motor does not rotate. With rising temperature, valve 28 closes to load piston 35 and close valve 38, decreasing flow through the orifice 14. Piston 13 moves up to restrict flow between lines 11, 19, and the motor rotates the fan. A manual screw 43 blocks a leak line 33 from the pilot valve 28 to provide fan drive if the thermostat fails. Again, Fig. 3, (not shown), valves 3 and 28 are mounted separate from valves 6 and 38, and are connected to chamber 40 by a conduit (49). Also, Fig. 4 (not shown), the orifice 14 is formed as an insert in the valve 6 piston, and valve 38 is loaded by a servo piston (51) in which slides a throttle edge (52) on a piston-rod (50) connected to the thermostat 3.

Abstract: 988,193. Weighing electrically. JOSEPH LUCAS (INDUSTRIES) Ltd. March 27, 1963 [April 17, 1962], No. 14778/62. Heading G1N. Apparatus for determining the weight on a weighbridge comprises a pair of strain gauges 9 at each corner of the weighing platform, each pair of gauges 9 being connected in a bridge circuit 8 with resistors which provide automatic temperature compensation, and is characterised in that the input and output cables 12, 16 are separate to avoid pick-up between them. A.C. power for the bridges is obtained from a transformer 13 located at or near the weighbridge, whereby the potential drop between the transformer secondary and the bridges is minimised, and the volts drop along the power cable 12 is reduced by the turns ratio of the transformer. The combined output from the bridges is automatically balanced against the voltages tapped off from three separately fed potentiometers 20, 21 22, the first preset to represent the unloaded weight of the weighbridge, and the second to represent the unloaded weight of a container. The densitivity of each bridge 8 is adjusted by an input rheostat 14, and the output impedances are equalised by series rheostats 15. The capacitative impedance to earth of the leads 16 may be different, resulting in different leak currents to earth. This is balanced out by adjustment of the earthing point of a potentiometer 26 across the difference amplifier 23. Specification 988,192, 988,194 and 988,195 are referred to.
