Patent GB-494505-A (GB)
Title: Improvements in or relating to permanent magnets
IPC: C22C38/16
Filed: 1937-04-27
Abstract: In order to obtain the maximum magnetomotive force for a magnet of given proportions, it is made from an alloy formed of one mixture from each of two classes, those in the first class being stated to form face-centred crystals which originate, but only feebly conduct, magnetic flux, and those in the second class being stated to form body-centred crystals which conduct the flux but only slightly originate it, the relative quantities employed of the two mixtures being dependent upon the proportions of the magnet in the manner stated below.  The Class I mixtures originating the flux, consist of definite proportions of aluminium, and iron with either or both nickel and cobalt, to which copper up to ten per cent may be added. The Class II mixtures, which provide the magnetic conductivity, consist of definite proportions of iron and either molybdenum, chromium, tungsten, or vanadium, or a mixture of any two or more of these mixtures may be employed.  The ratio of the weight of the Class I mixture to that of the Class II mixture employed in forming the alloy is directly proportional to the ratio of the area of the pole face of the magnet to the distance between the pole faces, being 75 per cent of the Class I mixture to 25 per cent of the Class II mixture when this latter ratio is unity, and 50 per cent to 50 per cent when the ratio is one quarter.  The magnets are preferably heated to a point where iron which has separated from the face-centred crystals is caused to recombine with them (according to the Provisional Specification, above 1280 DEG  C.) and then rapidly cooled, after which they are preferably reheated to a temperature of about 750 DEG  C.

Filed: 1947-02-18
Abstract: 636,000. Automatic control systems for engines. HALL, L. L. Feb. 18, 1947, No. 4674. [Class 38 (iv)] The fluid fuel supply to an engine is controlled by an electric relay which is energized in accordance with two factors, the product of which is proportional to engine load. As shown, Fig. 1, the engine governor comprises the soft iron yokes 1, 2 which support the winding 3 and between which the coil 4 moves in the gap magnetic field, in the direction of the arrows and against the restoring spring 6 in accordance with the product of the currents in the coils 3, 4. Coil 4 is mechanically coupled to the fuel or working medium control valve. Where the prime mover drives a generator, the governor may be connected as a watt-meter to the output of the latter while if a mechanical load is driven through a shaft, electrical signals proportional to the shaft speed and torque are applied to the coils 3, 4 respectively.

Patent GB-271153-A (GB)
Title: Improvements in or relating to protective arrangements for a.c. electric circuits
IPC: H02H3/30
Filed: 1926-02-18
Abstract: 271,153. Reyrolle & Co., Ltd., A., and Biles, R. W. Feb. 18, 1926. Cut-out arrangements.- In a Merz-Price type protective system the usual auxiliary battery for energizing the tripping coils when the relays operate on fault is dispensed with and the tripping current derived from separate auxiliary current transformers in the line, such independent circuit being so arranged that when the relays operate one or more of the trip coils are energized from the separate current transformer secondaries. As shown in Fig. 1 applied to a three-phase feeder with the secondaries A, A<1>, A<2> of current transformers in the line connected in reversed delta in the two-core pilot circuit B, B<1> in which the operating coils of relays C are connected at the ends, the relays serve normally to short-circuit the trip D, D' of the circuit-breaker at each end. These trip coils are connected each across one of the secondaries F, F<1>, F<2> of three additional current transformers in the lines, the secondaries being interconnected in reversed-delta.. When the relays C open, on disturbance of balance, the shortcircuit on the tripping coils is removed and the coils derive tripping current from the additional transformers. The invention is applicable in the same way to three-core pilot systems in which one relay in each pilot core short-circuits one of three tripping coils each across one of the additional current transformer secondaries. Alternatively, one relay may normally short-circuit one trip coil and the other two relays in series may short circuit the other, two tripping coils being used. In the arrangement shown in Fig. 4, where the middle current transformer N<1> differs in ratio from the others, a single tripping coil 0 is used shortcircuited by each of the relays C, C<1>, C<2>. Specification 270,410 is referred to.
