Title: Electromagnetic actuators
IPC: H01F7/14
Filed: 1972-01-15
Abstract: 1422121 Regulating IC engine fuel injection CAV Ltd 9 Jan 1973 [15 Jan 1972] 2019/72 Heading F1B [Also in Division H1] A rotary magnetic conductor, Figs. 1, 2, comprises a stator with four laminated C cores 10 defining arcuate polefaces and wound with current coils 11; all equiangularly spaced about an axis and located within casing 9. A rotor comprises a pair of laminated discs 13 mounted on axial shaft 12 journelled in non-magnetic end-plates and having an equiangular castellated profile with salient poles 14. Adjacent cores are oppositely polarized and with the discs define a magnetic circuit whose. reluctance depends on the alignment of the cores and the poles, which an energization tend to align themselves to reduce reluctance and to generate torque on the rotor shaft. The device may comprise any number of pairs of cores and poles, and alternatively the respective adjacent pairs of poles may be excited to similar polarities. In a modification, Figs. 3, 4, a pair of C cores 15 define an arcuate inner surface recessed to define polepieces 16, and a square shaft 17 carries four C cores 18 radially extending to define arcuate poles 19; the cores and poles being laminated and the cores being energized by a single coil. Four magnetic circuits are comprised by a core 18, poles 19, and a portion of a core 15 with a pair of polepieces 16. On energization poles 19 rotate to reduce reluctance and develop shaft torque; the polepieces 16 being of similar polarities. In further modifications, Figs. 5, 6, (not shown) the stator is formed of four separate inward C cores defining polepieces, or, Figs. 7, 8, (not shown) a rotor similar to that of Figs. 1, 2 cooperates with stator similar to that of Figs. 3, 4 or Fig. 9 (not shown) a rotor similar to that of Figs. 1, 2 co-operates with a stator comprising four C cores with inwardly projecting arcuate polepieces. Alternatively a rotor structure of the kind shown in Fig. 3 co-operates with a stator having a pair of surrounding axially spaced laminated annular members with inwardly extending polepieces numerically and positionally corresponding with the rotor poles, in which a coil is wound on each diametrically opposed polepiece of the stator. The coils may be excited with pulsed D.C. and the actuator may operate the control rod of a fuel pump for an I.C. engine which is driven therefrom; the screen actuator current being controlled by an amplifier including a switching output transistor, which is responsive to transducers detecting e.g. demanded speed and actual speed and also to the control rod position; the latter being resiliently biased to a minimum fuel supply position whereby fuel supply is adjusted to the demand and engine speed is limited to a safe valve, Fig. 10, (not shown).

Abstract: 623,093. Trimming moulded gramophone discs. COLUMBIA RECORDING CORPORATION. Aug. 16, 1946, No. 24506. Convention date, Aug. 18, 1945. [Class 87 (ii)] [Also in Group XXIII] A machine for rotating moulded gramophone discs whilst finishing means are brought to bear on the edges of the discs comprises a table whereon the stacked discs are held by a clamp, a motor for rotating the table, and means for applying power to the motor only when the clamp is engaged. A stack of discs 12 interleaved with paper spacers is mounted on a spool 11 and the spool is placed on a rotary table 42. A clamping- plate 81 is lowered on to the stack to secure it in position on the table. The clamping-plate is carried on a shaft mounted in bearings in a sleeve 62 that is lowered, to clamp the plate 81 on to the records, by depressing a pedal 100. The padal is connected to the sleeve by rod 117 and levers 121, 128 fulcrummed at 122. The pedal 100 works within a plate 102 having a slot 103 and notch 104. Only when the pedal is in the notch and the plate 81 is clamped on the records is a switch 108 operated to start an electric motor 17 that turns the table 42. As the assembly 12 - 11 - 42 - 81 is rotated by the motor, the operator applies a sand-paper pad or other abrading means to the edges of the rotating discs to remove the fragments of the peripheral fins left by the moulding operation. The edges of the discs are then buffed by a wire buffing brush 165, which is swung from an inoperative position against the stack by means of a handle 170. The brush is rotated by an electric motor 167. Wax polish is then applied to the disc edges by a hand brush, motor 17 is stopped, brakes are applied to the rotating assembly, clamping-plate 81 is raised and the stack removed from table 42. The brakes 50, 52 are applied by depressing the pedal to the bottom 106 of the slot 103, the connection between the pedal and the brakes including rod 140 and levers 145, 147 pivoted on shaft 146. An exhaust pipe 175 removes dust and debris.

At least one float frame 30 carrying groundworking tools 31 has draft means preferably comprising brackets 32, 35 and links 33 or arms 79 and tubes 72 Fig. 4 held in place by releasable arms 73, which permit vertical movement of the forward end of the float frame and means, for example, spring 54 supporting the rear of the float frame from the main frame at a predetermined distance therebelow. Control means which may be in the form of rock bar 40 arms 41 and 45 link 42 and chain 46 operatively connect the forward end of the float frame to the wheel support arm 19 to effect an additional vertical movement of the forward end of the float frame in response to vertical movement of the main frame. Alternative control means are shown in Fig. 4 comprising rock tube 65 arms 66 and 67', link 70 and extensible link 81. Detachable 'T'-bars 51, Fig. 5 may be employed when connecting the frames together and fit into slots in longitudinal members 53, the apparatus being such that accurate alignment of the main frame over the float frame is unnecessary for connection. To aid in positioning the frames a connection main frame guide member 60 is provided which cooperates with member 61 on member 35 as the float frames are raised from the ground.

Title: Improvements in and relating to windscreen washer devices
IPC: B60S1/48
Filed: 1964-01-21
Abstract: 981,861. Windscreen washer control systems. ROBERT BOSCH G.m.b.H. Jan. 21, 1964 [Jan. 31, 1963], No. 2530/64. Heading A4F. An electrically operable windscreen washer device comprises a valve 11 operable by an electromagnet 14, located in series with manually operable switch 20, and an electric wiper motor 1, located in series with a second manually operable switch 21, controlling parking switch 22, connected in parallel with the second switch 21 in which the switches 20, 21, 22 are so connected in parallel that the first switch circuit 17 contains the electromagnet 14 and the motor 1 in series, whilst the other switch circuits 18, 19, contain only the motor 1. The wiper, only is operated by closing switch 21. Wiper and washer are operated together by closing switch 20 only, when current from battery 16 opens valve 11 by means of electromagnet 14, and also operates motor 1, until parking switch 22 is closed by rotation of cam 23 driven by motor 1, which occurs when wiper arm 7 is in other than its rest position. Thus the arm 7 can be parked due to switch 22 remaining closed, even when switches 20 and 21 are open until the arm 7 is in its parking position. When switch 22 is closed, insufficient current passes through circuit 17 to operate electromagnet 14, so that fluid is only sprayed intermittently on to windscreen 8 when arm 7 passes through its parking position, and switch 22 is temporarily open. Modifications are described in which switches 20, 21 are replaced by a single two position switch, and in which switch 20 is replaced by a push-button switch having a timing switch in parallel with it, to allow the washing fluid to be intermittently sprayed for a predetermined number of wiper blade strokes during the washing and wiping cycle.

When the tubes are deflated, the bleed air can pass to the space between the outer and intermediate casing walls 12, 13 and thence through ducts 23 to inlet orifices 24 disposed between, say, the inlet guide vanes 22 to re-enter the working duct. A longitudinally corrugated strengthening ring 15 is brazed to the walls 12, 13 at the tips of the corrugations.
