Patent GB-258961-A (GB)
Title: Improvements in or relating to protective apparatus for alternating current electriccircuits
IPC: H02H3/08
Filed: 1925-07-04
Abstract: 258,961. Reyrolle & Co., Ltd., A., and Biles, R. W. July 4, 1925. Cut-out arrangements; induction relays.-The tripping-coil C<2>, Fig. 1, of an overload circuit-breaker is energized from the secondary B' of a current transformer in the circuit to be protected through a relay A so that, normally, the relay alone is in circuit with the secondary winding but, when an overload or other disturbance occurs, the tripping coil is connected with the secondary winding and the relay is cut out of circuit. As shown in Fig. 1, on overload &c. the relay contact-member A<1> is carried over from contact A<3> to A<2> to effect the desired connections. In order to ensure that the current in the relay coil is not broken until it has effected the necessary switching action, the contact-member A may be provided with two springy contacts one of which does not leave the contact A<3> until the other has reached the contact A<2>. Alternatively the fixed contacts may be close together and a broad movable contact-member used to ensure the same result. The contact-member may be automatically retained in its displaced position by a hand-released detent F<4>, Fig. 2. In the arrangement shown in Fig. 2, an induction relay is employed and operates the contact-member by winding up a cord E<3> so that a time-lag is introduced into the action. The contact-member switches the supply from the transformer secondary H<1> over from the relay coil D to the tripping coil H. The relay may normally short-circuit the tripping coil and, on overload, remove the short-circuit and then short-circuit the relay. As applied to a balanced protective system of the Merz-Price type the relays T, Fig. 7, are in the pilot wire circuit and serve to connect the tripping coils S across the reverse-delta-connected transformers R, R<1>, R<2>.

Title: Improvements in power plant for aircraft
IPC: F01N5/00
Filed: 1942-12-03
Abstract: 565,531. Heating aircraft. MACKIRDY, W. Dec. 3, 1942, No. 17226. [Class 64 (ii)] [Also in Groups XXVI and XXXIII] A power plant for an aircraft comprises one or more internal-combustion engines 10, and one or more other type heat engines 11 driven by a gas, such as carbon dioxide, which is heated by the exhaust, and cooling medium, of the internal-combustion engines. The engines 11 may have valve gear &c. to allow them to operate as internal-combustion engines, at low altitudes, and as heat engines using the Rankine or Carnot cycle, at high altitudes. All the engines drive propellers. An additional engine 12 is used to drive auxiliaries such as electric generators, air compressors, &c., and heat engines 28, 29 drive acompressor 36 (for the carbon dioxide), and a pump 16 (for the liquid carbon dioxide) respectively. When the engines 11 operate as second type heat engines, the working fluid passes through a closed circuit. Air for the internal-combustion engines passes through a heat-exchanger 14, supercharger 26 (driven by a turbine 27) and cooler 46 through lines 15. Fuel is supplied through conduits 31. The CO2, or other gas, passes through heat exchangers 17, 18, where the incoming CO2 is heated, before entering the compressor 36 and heat-exchanger 14, where the C02 is liquified. The incoming C02 passes through pipes 19 to a main heat-exchanger 20 heated by exhaust gases from the internal-combustion engines passing through pipes 21. The heated CO2 passes through pipes 22 to the engines 11 and other prime movers. Heat from the cooling jackets of the engines 10 may be utilised in the heat-exchanger 17, the liquid afterwards passing to a radiator 24. The compression ratios of the compressor 15 and pump 16 may be adjustable. The exhaust gas from the engines 10 may be used in heaters 30 for preventing ice formation on various exposed surfaces of the aircraft. The heat-exchanger tubes 31, 32 (see Fig. 3) may form part of the structure of the walls of the fuselage, which may be of the pressure-cabin type. The helices of the tubes are joined by webs 33 and have coverings 34, 35. The fluids in the tubes flow in opposite directions. The tubes and webs may be cast from light alloy to form a structure which is attached to the fuselage by brackets. Air for the pressure-cabin may be obtained from the conduit between the supercharger and the air cooler. Specification 565,560 is referred to.

Title: Improvements in mixing apparatus and method
IPC: B29B7/56
Filed: 1959-05-22
Abstract: 847,588. Mixing - machines. UNITED STATES RUBBER CO. May 22, 1959 [May 23, 1958], No. 17445/59. Class 86 In a mixing mill of the kind comprising a pair of rollers 14, 16, means 60 are provided near the nip between the rollers for moving the material, during its repeated traverses between the rollers, longitudinally along the nip, and at each traverse, cutting the material into strips and reorientating the material as it is again fed to the nip so that the strips are at right angles to their former disposition. The means 60 consist of a three-sided hollow bar with concave downwardly directed sides, the side facing the slower roller 14 being formed with helical flights 94 having sharpened edges 96 facing the sheet of material re-entering the nip. The material, e.g. rubber, may be fed as lumps or pellets, but as shown it is fed as a strip F from an extruder 110. The strip is fed to the roller 14 at a position between the righthand flight 94 and an end plate 92 of the member 60. The rubber builds up into a rolling bank between the member 60 and the roller 14, passes between the rollers, adheres to the roller 14 and is returned, as a wider strip, to the action of the member 60, which consists in cutting the strip into two parts by the knife 96 on the first flight 94, the right-hand strip re-entering the original rolling bank and the left-hand strip joining a rolling bank on the other side of the flight 94, the helical form of the flight turning the strip as it is cut through a right angle so as to reduce striation effects in the mixture. The helical form also effects a general feed of the material along the rollers, the strip of mixed material being removed for discharge at 106 by knives 104 which may be adjustably spaced according to the desired width of the strip. The member 60 may be vertically adjusted by handwheels 50, 54 and screw supports 56, 58, and may be canted by means 78, 80, to vary the re-orientating and longitudinal feed action of the member 60. One or more materials may be fed on to the roller 14 from hoppers supported by a frame 26, at different points along the roller; and two or more machines may be used in series to mix a number of materials. The member 60 is supplied with an attemperating medium, and may have flights which are non-uniformly spaced and pitched. The entrance edge of the member 60 may be downturned to confine material in the rolling bank which may have a tendency to escape from the bank.

Filed: 1948-06-30
Abstract: 658,833. Valve amplifying circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 30, 1948, No. 17542. [Class 40 (vi)] A negative feed-back amplifier comprises an element, such as a transformer 2, which causes relative phase shift of signals of certain frequencies, a feed-back path being provided from a .point after this element to the input, containing means which exclude these frequencies from this path, and a second feed-back path being provided from in front of this element to the input for feeding back the certain frequencies. In the example shown the oscillations of frequencies which have no substantial phase shift in the transformer produce oscillations of the same amplitude and phase at the upper terminal of resistance 20 and the lower terminal of resistance 17 and are thus fed unaffected from resistance 17 through condenser 18 to the input of valve 6. The frequencies which suffer phase shift, however, are substantially attenuated as they proceed beyond resistance 17. As, however, the condenser 19 offers a low impedance for these particular frequencies they are fed back by the second path which includes resistance 20, condensers 19, and 18 to valve 6. Specification 456,450 is referred to.
