Title: Electromagnetic rotary actuators
IPC: H01F7/14
Filed: 1973-03-21
Abstract: 1461397 Electromagnetic activators CAV Ltd 5 March 1974 [21 March 1973] 13570/73 Heading H1P A rotary electromagnetic activator comprises (Fig. 1) a stator 10 with laminated yoke 11 defining opposed curved laminated polepieces 12 and excited by winding 14 carrying unidirectional or pulsed current and embracing a rotor 15 on a shaft 16 axial of the gap. The rotor is laminated and so shaped that opposed curved polepieces 18 project from its cylindrical surface to define a small airgap with the polepieces 12 so that on energization the rotor is rotated to minimize reluctance of the magnetic circuit. The faces of elements 18 have tapered slots 19 therein with maximum width at minimum overlap of polepieces 18, 12 and minimum or zero width at alignment thereof, and the slots are formed by relative displacement of the laminations of pole elements 18. Plural slots may be provided. Corresponding V- projections are formed at the edges of the pole elements opposed to those containing the slots, and the laminations may be similarly displaced at the axial extremities of the rotor to provide cutaway portions therein. In a modification (Fig. 3, not shown) the faces of the projecting polar elements are machined with plural rectangular slots of maximum depth at the leading edges of the elements and minimum depth at the trailing edges. The effect of slots 19 is to reduce the overall effective length of the polar elements and alternatively the slots may be correspondingly provided in the pole faces 12. The resulting torque/rotation characteristic is thus made constant over a required angle of movement, and the axial length of the rotor pole elements may be equal to or less than that of the stator polepieces; and the slots may extend through the entire circumferential length of the polar element or polepiece faces; their width or depth being varied to provide a required torque/rotation characteristic.

Title: Improvements in signalling in wireless telegraphy
IPC: H03B11/08
Filed: 1916-09-27
Abstract: 142,141. Skipwith, H. L. d'E., Madge, H. A., and Airey, H. Morris-. Sept. 27, 1916. Wireless telegraphy and signalling.-Relates to systems in which electrical vibrations are produced by an arc connected with a self-inductance and capacity, for example as described in Specifications 15599/03, 6217/06, 27956/06, 4802/07, and 4809/07. According to the invention, two independent oscillatory circuits are permanently connected across the arc and provided with means for producing energy loss in one circuit or the other at will. For example, as shown in Fig. 9, the aerial circuit L', S' is in series with a capacity K and inductance J, and a separate circuit R<2> is arranged to have mutual inductance with the other oscillatory circuit L<2> S<2>, so that by adjusting this mutual inductance, the efficiency of the circuit L<2>, S<2> may be brought down practically to equal that of the aerial circuit L<1>, S<1>. For sending signals, the relative officiencies are quickly altered by alternately shunting the inductance J or a part of the inductance L<2> with a resistance R by means of a switch A. In this arrangement, a second switch B is adapted to close immediately after, and to open immediately before, the switch A, in order to short-circuit the junction between K and L' to earth E when the resistance R is shunted on the inductance J. A large resistance T is placed across the switch B to prevent accumulation of a charge in the condenser K without damping the aerial circuit. In another arrangement, instead of the switch B and resistance T, a switch is used in the aerial circuit. For transmitting discontinuous signals, a rotary commutator is put across the switch A. It is found that the switch A sparks on closing. To prevent this when large powers are in use, the switch is made with a number of contacts connected in series by high resistances successively cut off as the switch is closed; or the switch is made to work in compressed air or other compressed gas. As shown in Fig. 11, the two fixed contacts 2, 3 are arranged one above the other in a casing 1 and are connected to terminals 5, 4; and the movable contact 6, 7 is carried by a frame 8 controlled by a spring 10 and worked by a solenoid 9. The frame 8 passes through, and is hermetically secured to, flexible diaphragms 11 which confine the compressed air or gas within the casing 1, while allowing the up-and-down movement of the frame 8.

Title: Cross bar switch
Inventor: FLEISSIG JAN
IPC: H01H67/26
Filed: 1953-05-19
Abstract: 770,515. Automatic exchange switches. TESLA, NARODNI PODNIK. May 19, 1953, No. 14014/53. Class 40 (4). The contacts of a cross-bar switch are held open by two sets of stops movable in perpendicular directions to release the contacts. The switch has sixteen fields each having sixteen groups of contacts 22 and the contacts when operated engage with horizontal bare-wire multipling wires 26 which extend across one field. Vertical and horizontal bars 2 extend across the switch and each vertical and horizontal row of fields is associated with field selecting bars 7, 8, respectively. To operate a group of contacts X, electromagnet I2 is energized to pull down the corresponding vertical field selecting bar 7, to position projections 32 in the paths of levers 33 pivoted on slides 18 extending across one field and sliding on the horizontal bars 2, 8. Electromagnets II2, III2 corresponding to the horizontal bar 2 required are operated to pull the horizontal field selecting bar 8 and the required horizontal bar 2 to the right, whereupon in the required field the two associated slides 18 are also moved to the right due to pin-and-slot devices 36, 37 and the engagement of the levers 33 with the projections 32 on the operated bar 7. Projections 21 forming one of the sets of stops and integral with the operated slide 18 on the bar 2 are thus removed from under the selected horizontal row of contacts in the required field. The energization of an electromagnet IV1 positions a cam 6 under one end of a lever 4, the other end of which projects through an aperture in the vertical bar 2 associated with the contact group X, so that operation of the electromagnet V2 corresponding to the required vertical row of fields lowers the appropriate vertical bar 2 on which slides one slide 17 in each field. Operation of the bars 7, 8 pertaining to the selected field has within this field positioned a projection 21 under a lever 38 engaging the slide 17 which is thus lowered by the vertical bar 2 to disengage projections 20 forming the other set of stops from the selected vertical row of contacts so that the selected contacts engage the associated multipling wires 26 which are mounted on the slides 18. When all the electromagnets are de-energized the operated slides 18, 17 are held operated by engagement of a projection 21, 41 with the operated contacts and a pivoted member 42, respectively. The contacts are released when the operated slide 17 is released due to the operation of another slide 17 in the same field.

Abstract: 668,706. Printers' composing - appliances. INTERTYPE, Ltd. June 7, 1950 [July 6, 1949], No. 14205/50. Class 100 (iii). Composing-sticks.- A composing hand-stick for use with matrices E, Fig. 3, bearing typecharacters P for photographic reproduction, which may be to a larger, smaller, or the same size, comprises an L-section platform 1, Figs. 1 and 3, to support a composed line of matrices, and an abutment 2 to support the end of the line, recessed at 16 to facilitate manual removal of the line to a photographic reproducing machine. A 12-point em-scale 3 is provided to read off the length of the composed line. Further em-scales a-h, Figs. 2 and 3, are provided on a drum 4 rotatable by a knob 9 to bring a selected scale into position at a window 13 in the platform 1. The scales may be on separate strips fitted in recesses on the drum or on a sheet wrapped round the drum, which is protected by a cover 14. Recesses on the face of one of the drum hubs 5 engage a spring-ball detent 12 to locate the drum correctly in any selected position. The scale b corresponds to the scale 3 and is used when reproduction is to be to the same size. When enlargement or reduction of the characters is to occur on reproduction, a scale is used to compensate for this so that the reproduced line is of the required length. Thus, if the composed type is from a 12-point font, the scales b-h respectively are used when reproduction is to be to 12, 14, 16, 18, 24, 30 or 36-point size respectively. Alternatively, 8 or 9-point size type may be used, and in this case the scale a is used for reduction to 6 or 7-point size respectively, and the scale c for enlargement to 10 or 11-point size. The resulting 7, 10, and 11-point sizes do not reproduce to a mathematically accurate desired length, but it is sufficiently accurate for practical use. If the characters having no ascending or'descending stems are made somewhat oversize, as is customary, the line more nearly approximates to the desired length. Specifications 496,927, 603,271 615,559 and 650,630, [all in Group XX], are referred to.
