Patent GB-1214213-A (GB)
Title: Electric generator
Inventor: LEWIS WILFRID BENNET
IPC: H02K21/14
Filed: 1968-06-25
Abstract: 1,214,213. Generators with permanent magnets. ATOMIC ENERGY OF CANADA Ltd. 25 June, 1968 [18 Sept., 1967], No. 30334/68. Heading H2A. An electric generator has an arrangement of magnetic shunts which pass the flux of an annular permanent magnet alternately through a path which links the coil and through a shortcircuit path which does not link the coil. In the construction shown, rotor R includes a plurality of annular magnet discs 11, of ferrite material, stacked together on shaft 10 with similar polarities adjacent. The discs are spaced by soft iron spacers 12 having outwardly projecting polepieces 13. The stator S comprises a tubular member of insulating material 26 having circumferential slots containing windings 20- 25. Secured to the inside surface of tube 26 are a plurality of elongated magnetic shunts 30 -36 which over part of the rotation of the rotor exactly bridge the adjacent motor poles 13 thereby short-circuiting the flux of the respective magnet 12 so that it does not link with a coil. When the flux is not short-circuited it will pass upwardly through tube 26 to cut the respective coil and this change in flux will induce a voltage in the coil. The shunt members are staggered so that a multiphase output is obtained. In an alternative construction the flux switching member is rotated between two stationary structures. The inner stator comprises annular magnet laminations separated by spacers which are extended radially to form teeth. The outer stator comprises a series of annular coils having magnetic shunt members around them which face the teeth on the inner stator. The rotating switch member consists of a tube of insulating material with segments of magnetic material spaced apart by the distance between the teeth and additional interposed slanting members which project only between the teeth of the inner stator, Figs. 6-10 (not shown).

Title: Improvements relating to interference suppression circuits for radio and television receiving apparatus
Inventor: FAUDELL CHARLES LESLIE
IPC: H04N5/21
Filed: 1948-11-23
Abstract: 668,839. Radio interference suppression circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 23, 1949 [Nov. 23, 1948], No. 30361/48. Class 40 (v). A noise suppression circuit in a radio receiver comprises a cathode follower valve having a signal delaying network connected between the control grid and the input signal source, and a unidirectionally conducting device connected between the source and a point in the cathode circuit of the valve, whereby signals of steep wave front cause the conductivity of the device to increase, and thus reduce the amplitude of such signals before they are applied to the control grid. The output is taken from the anode load impedance. In Fig. 1, audio frequency signals are applied via terminal 4 and delay circuit 8, 9 to the grid of cathode follower valve 1. The input circuit is shunted by diode 10 in series with audio frequency by-pass condenser 12. Diode 10 is biased by the voltage across cathode resistance 2 and also the potentiometer effect due to resistances 13, 11 and 2, so that it is normally non-conducting, but in the event of a steep interference positive impulse, the delay circuit 8, 9 prevents the cathode voltage from immediately following that of the input waveform applied to terminal 4, and diode 10 conducts to shunt away the noise impulse. The output is taken from the anode of valve 1. In an alternative arrangement, the bias leads to the cathode of the diode, the control grid and the cathode of valve 1 are all connected to tappings on a resistance forming part of a potentiometer between H.T. and earth. The Provisional Specification describes other arrangements in which the by-pass condenser 12 and the bias supply potentiometer are omitted, and also describes an arrangement (Fig. 2) in which a double-diode-triode valve is used to demodulate signals applied through transformer 17, so that audio frequency signals are applied through condenser 22 and resistance 8 to the control grid 13. Resistance 8 and condenser 9 provide a signal delay network, and diode 16 is connected between the audio signal input point and the common cathode 12. A further diode may be employed in any of the circuits which is connected in the reverse sense so that the amplitude of steep negative pulses may also be reduced. Specification 532,621 is referred to.

Filed: 1946-10-18
Abstract: 618,329. Average-speed indicators. MORRIS MOTORS, Ltd., and LANDSTAD, H. F. Oct. 18, 1946, No. 30992. [Class 106 (iii)] An instrument for continuously indicating the average speed of a road vehicle comprises mileage and time-indicating mechanisms actuating angularly movable co-operating indicators arranged to intersect over a set of average speed curves correlated with mileage and time scales associated with the respective indicators, and is characterized in that the mileageindicating mechanism includes a planet carrier (25), the planet gear of which meshes simultaneously with a concentric pair of spur gears, one of which is immovable and has n teeth, and the other of which is rotatable by the planet gear and has n-1 teeth. A pointer 6, driven by a normal clockwork mechanism 9 through a gear-wheel 10 and sector 12, indicates running time on a scale 3. The other pointer 7 is driven by a high-reduction gear from the road wheels and indicates mileage on a scale 2. Curves 5 form an average speed scale for reading off the point of intersection 8 of the two pointers 6 and 7. The drive from the road wheels is transmitted through gears 17 and 18 to a worm 22 driving a worm-wheel 23 integral with a planet gear carrier 25. The planet gear 26 rolls round a fixed gear 27 and a gear 28 having one tooth less than the latter. Thus, the gear 28 rotates slowly, turning a snail cam 35 which rocks a pawl lever 36 gradually to the left until the fall in the cam allows a spring 39 to bring it quickly back. The pawl 40 rotates a ratchet - wheel 41 which is geared. to the pointer. Slipping clutches (45a for pointer 7 and 11 for pointer 6) allow for zeroizing the pointers manually, extensions 45 and 14 being provided for this purpose. A knob 46 is provided for winding the clock mechanism.

Filed: 1952-12-08
Abstract: 722,780. Exhaust silencers. CAULKINS, C. P. Dec. 8, 1952, No. 31119/52. Class 7 (2). [Also in Group XXI] In a device for silencing the gases discharged from an internal-combustion engine the wall of gas chamber A between longitudinally spaced and relatively movable rigid heads 10, 20 is formed by a number of closely assembled, longitudinally disposed resilient members 30, e.g., wires of cylindrical cross-section and of heat-resistant material. One of the heads 10 is provided with an intake opening 11 which may be smaller in diameter than the chamber A, the forward portion of the head being decreased in diameter and having a groove 16 into which the ends of the wires 30 are bent inwardly and secured in place by a collar 17 driven over the wires ; the wires are fixed to the head 20 in a manner similar to that employed for the head 10. A shroud 18 extending around the wires 30 may be secured to the head 10. In operation, the gases expand in the chamber A and cause the wires 30 to bow outwardly, the longitudinal openings formed between the wires allowing the gases to escape. The bowing of the wires draws the head 20 towards the head 10, this movement being resisted by the pressure of the gases on the head 20 and producing a vibration of the wires to prevent an accumulation of carbon on the wires. In a modification, Fig. 6, the diameters of the head 20A are larger than those of the head 10 so that the wires are farther apart at the outlet end than at the inlet end of the device, and a shroud 40 having one end affixed to the head 20A and the other end slidably supported on the head 10 provides a chamber B surrounding the chamber A. The shroud has an enlarged outer end to add an annular area 41 to that of the inner end 26 of the head 20A, and a series of angularly spaced, substantially longitudinally disposed slots 42 providing for the egress of gases in the chamber B, the slots being positioned at the intake end of the device and cut at an angle so that the direction of flow of the gases is reversed. In further modifications, (a), Fig. 9 (not shown), the members 30 comprise solid strips of rectangular cross-section, angularly disposed in relation to the axis of the device and parallel to one another, and there is an outer layer of spaced apart strips disposed at an angularity opposite to that of the inner strips, (b), Fig. 11, the wires 30 are disposed between a head 50 secured by a ring 51 to a pipe 52 and carrying a shroud 53 having an open outer end 54, and a ring 58 is slidably supported on a collar 57 attached to an imperforate disc 55 affixed to the shroud by radially extending arms 56, and (c) Fig. 13 (not shown), the ring 58 is replaced by a head provided with vents, the wires 30 being fixed to the head as shown in Fig. 2.
