Abstract: 1,115,522. Semi-conductor circuits; controlled saturable reactor circuits. GLOBE INDUSTRIES Inc. 28 May, 1965 [25 Aug., 1964], No. 22760/65. Headings H3B and H3T. [Also in Division H2] A brushless D.C. motor has a permanent magnet rotor and a plurality of stator windings energized in sequence by silicon controlled rectifiers (SCR's) rendered conductive sequentially by an electromagnetic sensing device in dependence on the rotor position. As shown in Fig. 1, a coupling loop 8, mounted on the end of the rotor successively couples winding 6 to auxiliary windings 1 . . . 5 and hence sequentially triggers the SCR's 14. . 414 from the oscillator 10. Assuming SCR 214 is triggered, transistors 236, 252 and diode 234 become conductive, directing current from left to right in stator windings 42, 40 and from right to left in stator windings 44, 46, 48. Commutating capacitors 64 ... 464 are connected between the anodes of successive SCR's so as to turn off the conductive SCR when the next one is triggered. The direction of current in stator coils 40 ... 48 is thus a function of the rotor position. In Fig. 2 (not shown), the transistors and diodes are omitted, each stator coil being in series with the anode of an SCR and is energized separately. In Fig. 5 (not shown), each SCR turns on a transistor which individually energizes an appropriate stator coil. In Fig. 6 (not shown), a unijunction transistor is interposed between the rotor position sensing device and the gate of each SCR. Saturable transformer switching arrangements.-Fig. 3 shows a motor in which the stator 536 carries a cylinder 542 housing a permanent magnet 562 and a plurality of toroidal transformers 508 . . . 518. The rotor shaft 541 carries a ferromagnetic member 554 and a brass portion 556. The primary windings of transformers 508 ... 518 are connected to an oscillator (Fig. 4, not shown) whilst each secondary is fed to the gate electrode of a respective SCR. The ferromagnetic portion 554 couples the field of magnet 562 to three of the transformers 508... 518, saturating their cores so that only the SCR's associated with the other transformers are turned on, passing current through three of the stator coils 532 ... 534 in any given position of the rotor so that a rotating magnetic field is produced.

Abstract: 1,237,939. Electrogasdynamic generators. GOURDINE SYSTEMS Inc. 20 Sept., 1968 [5 Oct., 1967], No. 44910/68. Heading H2A. An EGD generator has a duct 10 in the form of a convergent/divergent nozzle consisting of three sections 10a, 10b, 10c and is provided with a high resistance path 30 effectively extending along the flow path boundary between the attractor and collector electrodes so that charged particles contacting the walls are returned to the upstream end of the duct. The presence of this path effectively prevents local stresses building up along the duct so that the voltage on collector electrode 18 can be inincreased. The path may be provided by a coating, either liquid or solid, within the duct or by making section 10b of the duet from a conducting ceramic material. Alternatively annular metal rings may be inserted between the dielectric blocks which form the duct wall and these rings are connected together through a resistance which could be formed by a deposit on the outside of the duct, Fig. 3 (not shown). Preferably the total resistance of the path between collector and attractor electrodes is greater than or equal to the load resistance. In the case where a liquid aerosol is used as working fluid it is necessary to make the return flow path at least as long as the operating part of the duct and various configurations of exhaust systems are described, Figs. 3-6 (not shown).

Abstract: 1,252,250. Feeding and delivering sheets. NATIONAL CASH REGISTER CO. 6 July, 1970 [1 Aug., 1969; 24 April, 1970], No. 32633/70. Heading B8R. A record media feeding and delivering device includes a separating means to remove sheet record media 2 one at a time from a pile, a feeding roller 11 for feeding the removed record media to a processing station, e.g. cheques to the shoot 1 of an encoder, and a delivering roller 15 for delivering the processed record media out of said station, a pressure roller 12 being movable into one operative position to co-operate with said feeding roller 11 and into a second operative position to co-operate with said delivering roller 15. The separating means may be a roller 4 on a reciprocable arm 9, the roller being held against rotation on sheet separating strokes to cause a sheet to buckle against, and then to flip over holding lips 10 on a pile magazine 3. Both this roller and the pressure roller 12 may be drivably connected to a segment 6 pivotable about a point 6b by a cam (not shown) engaging a follower roller 6a such that when pivoted anticlockwise a record media sheet 2 is separated from the pile, which is spring-biased upwardly against the separating roller 4, and the pressure roller 12 is moved into contact with the feeding roller 11 to feed the sheet to the shoot 1 whilst subsequent clockwise movement moves the pressure roller into contact with roller 15 to remove the sheet from the shoot 1, an additional roller 16 being moved into contact with roller 11 to deliver the sheet to a collecting station. The separating roller 4 may alternatively be reciprocated via linkage connected to a bellcrank (20), Fig. 2 (not shown), rocked in synchronism with the segment 6, an electromagnet (32) being operable to actuate a latch plate (31) which renders the linkage inoperative and therefore prevents reciprocation of the separating roller 4 when required. A photoelectric cell (not shown), may detect incorrectly positioned record media in the shoot 1 and prevent activation of the encoder.

Abstract: 1,252,690. Supercharged I.C. engines; rotary compressors. E. KICKBUSCH. Aug.21, 1969 [Aug.22, 1968; Oct. 31, 1968; July 11, 1969], No.41858/69. Headings F1B and F1F. An I.C. compression-ignition engine is charged with air by a positive-displacement compressor 23, Fig. 6, driven by an exhaust-gas turbine 12 via a hydrodynamic transmission. The latter is arranged to drive the compressor at substantially constant speed over a wide range of engine speeds, so that the engine torque increases with reduction in engine speed, and engine power thereby remains substantially constant. The transmission comprises a torque converter 56 having pump and turbine sections 14, 17. The converter may have adjustable vanes or a filling and emptying device. Liquid continuously removed from the converter passes through cooler 19 and pressure-maintaining device 20 and returns at 21. The converter pump and turbine sections may be arranged physically divided from one another and in fluid communication through a pipe, the working liquid being obtained from an existing lubricating oil or hydraulic transmission circuit. A converter of the divided type may receive the discharge of an engine-driven oil pump to provide additional driving power to the compressor 23. An additional drive for the compressor 23, comprising a centrifugal clutch 26, belt 27, shaft, 30, free-wheel device 31, gears 32, 33 and, optionally, a converter 57, is rendered inoperative above a certain speed. In a sixcylinder in line engine, Fig. 9 (not shown), the first three cylinders discharge into a common exhaust manifold (67), and the last three cylinders discharge into another common exhaust manifold (68). Both manifolds have their discharge ends formed as nozzles (69, 70) assembled concentrically about each other to discharge into the spiral casing 11 of the turbine 12 to mix the pulsating exhaust flows upstream of the gas turbine wheel. To achieve smokeless combustion during starting and acceleration, additional charging air is supplied from an air receiver, e.g. of a brake system, since the additional air cannot be supplied instantaneously by the charging compressor. A large proportion of the fuel can be injected into the suction line of the charging compressor to cool the air charge and to improve combustion within the engine. The positive-displacement compressor comprises an outer rotor 38, Fig. 7 having internal cyloidal toothing with six teeth, and an eccentric inner rotor 48 having external cycloidal toothing with five teeth. Air enters at 24 and passes through a segmental opening (45), Fig.8 (not shown), in wall 42 into the spaces between the co-operating teeth of the rotors 38, 48 where it is compressed and forced through clack valves 53 into a spiral discharge duct 35. The clack valves are provided with torsion springs 54 and with counterweights 55 which prevent the valves from opening centrifugally.

The stem 56 has a portion of reduced diameter immediately adjacent to the ball 54 so that, on impact, the mirror assembly 18 will snap off at the socket 44. The socket 44 is extended over and around an opening 58 in the protrusion 48 so that the opening 58 is sealed in any angular position of the mirror assembly 18. At one end 64, the spring 60 has a recessed portion 66 which is provided with a threaded aperture 68 for engagement with a fastener 70. At the other end, the spring 60 has two slots 71 and 73 so as to provide tongues 74 and 76 for engagement with apertures 78 and 80 in a front wall portion 21 of the support base 20. The portion of the spring 60 between the slots 71, 73 forms a leg portion 82 which is inserted through an aperture 17 in car wing 16 and is bent at its end to form a retaining finger 84. In a further embodiment described with reference to Figs. 5 and 6 (not shown), the ball member (54) is frictionally retained within the ball socket of the spherical protrusion by two oppositely disposed and facing spring members. The mirror glass 26 is retained within the casing 28 by a resilient snap ring member 32 which snaps over a radial flange 30 and the lateral flange portion.
