Filed: 1966-10-21
Abstract: 1,170,767. Alternators. NATIONAL RESEARCH DEVELOPMENT CORP. 11 Oct., 1967 [21 Oct., 1966], No. 47426/66. Heading H2A. An alternator has a very small air-gap so that it has a drooping characteristic caused by armature reaction and so is suitable for constant current load. In addition, the field windings are uniformly distributed over the rotor so that the output current, reflecting this square-wave ampere-turn distribution because of the large armature-reaction, also tends to be of squarewave shape. This makes it especially suitable for rectification. In effect, the close air-gap and low load impedance means that the working flux is very low, and the output current is a reflection of the rotor current. The machine resembles a current transformer while the conventional alternator resembles a voltage transformer. The machine is switched off by being short-circuited. Six phases may be derived from three stator coils by using bifilar wire. Alternatively, nine phases may be used in three rectified series groups. The excitation may be currentcompounded.

Abstract: 1,011,106. Electromechanical delay lines. A. C. COSSAR Ltd. March 5, 1964 [Dec. 20, 1962], No. 48184/62. Heading H3U. A delay line comprises a plurality of strips of material fixed together in register to form a stack 11 and electromechanical transducers 16, 17 bonded to the end-faces of the strips at respective ends of the stack, the arrangement being such that on the application of an electrical input to one transducer transverse elastic shear waves are produced in the strips which actuate the other transducer to produce a corresponding electrical output delayed with respect to the input. In the arrangement illustrated six strips of aluminium or nickel alloy are clamped together at their ends by clamps mounted upon an electrically conducting base 14. Piezo-electric thickness-shear-mode transducers 16, 17 of lead zirconium titanate or barium titanate are bonded to the end faces of the stack by eutectic tin-bismuth solder. The delay line is sealed in a cylindrical constanttemperature enclosure 15 around which is wound a thermostatically controlled heating coil 23. The enclosure 15 is closed by endplates 24 and 25; plate 24 carries one terminal 21 which is connected to one electrode of the transducer 17, the other electrode being connected to the base 14. Plate 25 carries four terminals of which only two are visible; one, 20, is connected to one electrode of transducer 16, the other electrode of which is connected to the base 14 and thence to one other electrode on the plate 25. Electrode 27 is connected to a thermostat 22 mounted on base 14 but insulated therefrom and thence to one end of heating coil 23, the other end of which is connected to the fourth terminal on plate 25. Absorbing thermosetting material, not visible in the Figure, is coated on the minor side edges of the stack; this reduces distortion of the wave motion which takes place in a direction parallel to the longitudinal axis of the end faces of the strips. Instead of being clamped together as shown the ends of the strips may be secured together by adhesive.
