Abstract: 483,797. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 25, 1937, No. 23335. Convention date, Sept. 11, 1936. [Class 40 (v)] To produce a clear-cut short-wave beam, free from secondary lobes, a doublet aerial 4 is arranged at the centre of an open-ended drum with a back wall 2. The reflector as a whole is constructed to have a linear focus, the aerial being located at that focus. The drum is shown in cross-section in Fig. 1A, and in elevation in Fig. 1B. The inside maximum diameter E exceeds the inside minimum diameter F by half a wave-length. A diffraction ring 10, which may be made of metal or of dielectric, is mounted in the plane of the open end of the drum. Its effect is to cause interference between the energy radiated through the two open zones A and C, and so produce a clear-cut beam. The transmitter or receiver 5 is located in a chamber formed between the back reflecting-surface of the drum and a cover plate 9, and is connected to the doublet 4 through a transmission line 6. As shown in Fig. 2, the drum is mounted for rotation about a, vertical and horizontal axis. Scales 21, 21a show the relative setting, and sights 14 are provided for directing the apparatus on a desired objective. The drum may be open-ended on both sides for combined transmission and reception, Fig. 4 (not shown), or it may contain a crossed pair of doublets, with a phase-displaced feed, to produce circularlypolarized waves, Fig. 3 (not shown). The same dipoles may be used for alternate transmission and reception by providing a changeover switch, Fig. 5 (not shown). British Specification 392,962 and U.S.A.

Title: Improvements in and relating to permanent magnet clutch-brakes
IPC: F16D37/02
Filed: 1951-10-08
Abstract: 693,955. Magnetic fluid clutch - brakes. BRITISH THOMSON -HOUSTON CO., Ltd. Oct. 8, 1951 [Oct. 11, 1950] , No. 23390/51. Class 80 (ii). [Also in Group XXXIV] A magnetic fluid combined clutch and brake device comprises a driving member, a driven member, brake means, gaps between the parts containing a magnetically susceptible mixture, magnetic means in one of the members to create a magnet field in the gaps, and shunt means for preventing the magnetic field from being created in one of the said gaps. As shown, a driving shaft 2 carries a member 14 with a magnetic ring inset 15, and a driven shaft 3 carries an armature formed by a permanent ring magnet 10 with pole pieces 11, 12. A fixed brake ring member 18 of magnetic material surrounds the armature and magnetically susceptible mixture 26. 27 fills the gaps between the parts. Non-magnetic rings 23, 25 and a magnetic ring 24 in the armature cause the magnetic flux to cross and recross the gaps and thus couple the parts together. Control means are provided in the form of an annulus 28 of magnetic material which acts as a shunt for the flux and is axially movable by a lever 32 acting through the linkwork shown. In the Figure, flux passes from the magnet 10 through parts 11, 28, 24 to the magnetically susceptible mixture 27, brake member 18 and pole piece 12, but bypasses the magnetically susceptible mixture 26, so that the driving and driven shafts 2, 3 are not coupled together and the driven shaft is braked. If the shunt is moved to the right, the flux passes through the magnetically susceptible mixture 26 to couple the driving and driven shafts but bypasses the magnetically susceptible mixture 27, the brake means accordingly being rendered ineffective. Specifications 649,553 and 688,247 are referred to.

Title: Improvements in or relating to a method and means for gutting fish
IPC: A22C25/14
Filed: 1939-08-17
Abstract: 533,649. Gutting fish. BUNDHEIM, E. Aug. 17, 1939, No. 23780. Convention date, Sept. 16, 1938. [Class 28 (ii)] A method of gutting fish, such as herrings, consists in holding the fish body in a retaining device, gripping the gill carriers lying between the gill covers by grippers and drawing them somewhat away from the remainder of the body, then with the parts in this position causing a separating blade to enter between the gill carriers and the mouth of the herring and sever the gill carriers (and with them the gills) from the lower jaw, then drawing the grippers and the fish apart, whereby the guts are drawn out, and finally pulling away any part which may remain hanging out and unremoved by the grippers. The fish are placed by hand from a table 32 into troughs 23, which are arranged in spaced relationship around a rotary disc 22 driven from a motor 12 and are provided with side walls hinged together. An equal number of pairs of grippers 21 (one pair only shown) are mounted on a disc 20, which is rotated at the same speed as the disc 22 but in the opposite direction. As each trough 23 approaches the disc 20, its side walls are rocked together by a cam 26 acting on a lever 24, and pins on the side walls enter the eyes of the fish and hold it firmly in position. As the gill carrier of the fish reaches approximately the horizontal position between the discs 20, 22, the grippers 21 are closed upon it by means of a fixed cam disc 36, and as the fish is carried downwards the grippers 21 move away from the trough 23 and draw out the gills &c., while a fixed pointed blade 37 enters the gill carrier and severs it from the mouth, the drawn out parts being released from the grippers by the cam 36 at a position over a discharge shoot 33. The remaining parts of the guts hanging out from the opening in the fish are gripped by a clamping device 30a, 31 operated by a rod 29 from a cam 30, and are thus removed, the fish being then released from the trough 23 by the cam 26 and allowed to drop out.

Title: The excitation of superconducting magnetic coils
IPC: H01F6/00
Filed: 1965-06-03
Abstract: 1,098,602. Superconducting magnets. SIEMENS - SCHUCKERTWERKE A.G. June 3, 1965 [June 19, 1964], No. 23822/65. Heading H1K. A superconducting magnetic coil with at least one parallel connected resistor is excited from a unidirectional source which is varied to provide a constant magnetizing voltage across the ends of the coil; provision may be made to reduce this voltage momentarily when flux jumping is likely to occur or as critical current is approached. Normally, the source voltage needs to be steadily increased to provide for increasing voltage drop in the external circuit as the coil current increases; predetermined programming may be utilized to effect short period reductions in source voltage to deal with sudden changes known to occur at particular current values in the particular coil employed, or the source voltage may be varied by a control signal derived from probes connected to the superconducting coil. In one embodiment, control is effected by a programmed motor drive varying an induction regulator (slowly) and a stepped transformer, the regulator and transformer each being associated with a rectifier, and the two rectifiers being connected in series; in another embodiment the applied voltage is compared with a predetermined master voltage and a controller or variable transistor is used to bring the applied voltage to the desired level. In another embodiment, the coil voltages across each half of the coil are compared in a differential transformer and any resulting signal is used for control or disconnection of the voltage source.
