Abstract: 1451165 Electric motors having brakes ELECTROLUX AB 16 Jan 1974 [19 Jan 1973] 02052/74 Heading H2A In an electric motor having a stator core 12 with at least two poles 13/14, a movable brake device 23/24 is partly disposed in a space 19 between adjacent poles, and has a part 23 of magnetizable material which is received within a core cut-out 15 radially outward of the space 19, the arrangement being such that magnetic flux in the core 12 causes the brake to be urged away from the rotor 10 of the motor, e.g. when the motor is energized. In practice, the reduced thickness portion 17 of the core at the cutout 15 becomes magnetically saturated at low flux levels, and the magnetizable part 23 of the brake is pulled firmly against the cutout to provide a path for the flux. When the motor supply is cut off, a spring 22 forces a non-magnetic, e.g. plastics, lining part 24 of the brake against the rotor 10. A further brake may co-operate with a further cut-out 16. In the embodiment of Figs. 2, 3 (not shown), a brake device comprises a laminated iron core (27) and two bolted-together brake blocks (28), each having a brake lining (32) and recesses (33). Pins (34) and flanges (35) guide the movement of the brake. In the arrangement of Fig. 4 (not shown), brake blocks (28) are formed wholly of lining material.

Abstract: 803,422. Centrifugal blowers. ECK, B. Jan. 26, 1955 [Jan. 27, 1954], No. 2362/55. Class 110 (1) In a radial-flow blower suitable for conveying gases having a high dust content, the blade angle is substantially the same at all points and greater than 38 degrees with respect to the periphery of the rotor, and a device for imparting a substantial whirl in an assisting direction is arranged on the input side of the rotor. The angle of the blades of the rotor 1, Fig. 1 of a blower with respect to the tangential direction is greater than the angle of friction (about 38-40 degrees) of the industrial dust contained in the air, to prevent adherence of the dust to the blades. Similarly, the curved entry part of the shroud 11 subtends, with respect to the blower axis, an angle greater than the angle of friction. For optimum efficiency, the ratio of the radius of curvature r of the shroud 11 to the inner diameter d1 of the rotor lies between 1/10 and 1/6; the ratio of the rotor width b1 to the inner diameter d1 lies between 1/3.6 and 1/2.8; and the ratio between the inner diameter d1 and the outer diameter d2 is greater than 0.55-0.6. Regulation can be provided by an adjustable plate 5 with, it may be, a simultaneous adjustment of guide blades. The guide blades may be twisted or resiliently deformed. Alternatively, the guide blades 6, Fig. 3, may be carried by an axially movable member 7.

Abstract: 772,536. Road-traffic signals on vehicles. BELLING & LEE, Ltd. April 20, 1955 [Jan. 27, 1954], No. 2508/54. Class 118 (2). [Also in Group XXXVII] A vehicle direction indicator system of the flashing-light kind comprises thermally responsive elements (see Group XXXVII) which only come into operation when the turn indicator switch is operated. Two bimetallic strips 4 and 7 carrying contacts 6 and 9 respectively complete the circuit from battery 1 via ignition switch 3 to the selector switch 16. Two heater windings 11 and 12 associated with strip 7 are respectively in parallel with left and right signalling lamps 15 and 14, and a heater winding 10 on strip 4 is normally short-circuited by the contacts 6, 9. When the switch 16 is moved to a selected side, e.g. to the left as shown, the winding 11 heats strip 7 which opens contacts 6, 9. This places winding 10 in series with the load which suffers a consequent drop in voltage, as does the parallel winding 11. Thus strip 4 is heated and tends to close contacts 6, 9 while strip 7 cools somewhat to aid such closure. The lamps 15 are meanwhile extinguished. As soon as contacts 6, 9 close lamps 15 light again and the cycle is repeated. The windings 10, 11 and 12 can be all the same and strips 4 and 7 may also be similar.

Jan. 27, 1931, No. 2683. Convention date, Feb. 24, 1930. [Class 40 (iii).] In a phase-shifting device 51, voltages of different phase angles, derived from an input circuit 50, are applied to points A .. D on impedance elements 52 forming a closed circuit, and an output circuit 55 is connected to a point on the input circuit and through a movable contact 56 to a point on the impedance elements. The invention is applied to synchronizing distributers in electric telegraphy. Manual operation, Fig. 2. Current is produced in the primary of a transformer 49 from a tuning fork adjusted in frequency by the phase relation of a distributer brush to the incoming signals, Fig. 1 (not shown), as described in Specification 317,528, [Class 40 (iii), Telegraphs, Electric]. The transformer is connected to the input transformer 50 supplying current to opposite points A, C of the closed resistance 52. The arm 56 contacting with the resistance, is connected to an output transformer 55, the secondary of which consumes virtually no current, so that the load is zero. When the arm is at the point A, the transformer 55 is in parallel with the right half of the transformer 50, and, when. the arm is at C, the transformer 55 is across the left half, so that a half revolution of the arm reverses the phase relation between the input and output currents. The phase variation due to the rotation of the arm 56 correspondingly affects the current in a resistance 58 and a relay 70 which controls the motor driving the distributer brushes. Automatic operation, Fig. 3. Current originating from a tuning fork 340 passes through amplifying valves 344, 347 and phase-splitting valves 360, 363, so adjusted that the voltage applied across points B, D on the resistance 352 of the phase-shifter 351 is 90‹ out of phase with the voltage across points A, C. The arm 356 of the phase-shifter is moved automatically by a motor 325 controlled by a differential relay from differential valves 323, whenever the distributer 314 is out of synchronism with the signals, and thus alters the phase of the current in the relay 370 controlling the driving motor.
