Title: Improvements in or relating to rotors for axial-flow turbines or compressors
Inventor: JENSON GEORGE
IPC: F01D5/24
Filed: 1963-02-01
Abstract: 998,198. Turbine and compressor blades. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 7, 1964 [Feb. 1, 1963], No. 4309/63. Heading FIT. The blades 1, Fig. 1, of an axial-flow compressor or turbine, such as a steam turbine, are laced together by a first sectionalized member 7 and a second sectionalized member 9, both of which pass through the same holes in all the blades at a constant or substantially constant distance from the rotational axis with each section capable of axial movement relative to the blades through which it passes, and, when the rotor is rotating at speed, together provide a limited frictional coupling between all blades, the ends of the sections of the first lacing member being staggered round the circumference of the rotor relative to the ends of the sections of the second lacing member. This arrangement improves the vibrational characteristics of the rotor blading without resulting in excessive tensile stress in the lacing members at high rotor speeds, since under such conditions relative slipping occurs between the lacing sections and between these sections and the blades. The ends of each lacing section are bent outwardly to prevent excessive circumferential creep. The lacing members 7, 9 are of semicircular cross-section with their interface lying with respect to the rotational axis, in a radial transverse plane or in the surface of a coaxial cylinder. Each lacing member may be hollow so that together they form an annular crosssection. In this case each lacing section may be formed from titanium sheet. In order to prevent the radially inner ends of hollow lacing members 37, 39, Fig. 5, from moving outwardly under the effects of centrifugal force a single or sectionalized support 41 is arranged in the radial transverse plane. With a single support 41, lips 37A, 39A are removed from the outwardly bent ends of the lacing sections.

Title: An improved method of metallisation by cathode disintegration
IPC: C23C14/34
Filed: 1937-02-13
Abstract: 470,614. Depositing metals by electric discharge. BERGHAUS, B. Feb. 13, 1937, Nos. 4384 and 4385. Convention dates, Feb. 21, 1936 and March 10, 1936. Drawings to Specification. [Class 41] In metallizing by cathode disintegration, the discharge is effected by pulsating or intermittent direct current and the cathode is heated by alternating, pulsating or intermittent direct current, the phase of which is so determined that heating and discharge take place alternately ; in this way deflection of the charged particles produced by the magnetic field of the heating current is reduced. Alternating current for heating of suitable phase may be derived from one limb of a three-phase transformer, the discharge current being derived from a whole-wave rectifier connected across the other two limbs. Capacities and inductances may be employed for phase adjustment in such manner that the maximum discharge voltage occurs when the heating current changes direction. Intermittent voltages of rectangular or trapezoidal form may be employed. The discharge is preferably effected by a pulsating direct voltage, the minimum of which does not fall below the extinguishing voltage. To reduce the magnetic field the cathode may be so arranged that the heating currents in adjacent wires are in opposite directions. It may consist of two relatively displaced rows of parallel wires lying in the same plane and oppositely connected. The wires may be supported at intervals by insulating bars. The wire may be of a metal of high melting point such as tantalum, chromium or tungsten or an alloy thereof; when other metals are to be disintegrated the wire is provided with a high melting core. Specification 390,319 is referred to.

[Also in Division G1] A high-power mercury arc rectifier 8 is tested under heavy load and high commutation (current) conditions by including it in an inverter circuit 4 which is connected to an oscillation circuit (capacitators 10, 11 and inductances 3, 12). A direct voltage source, consisting of a supply 1 feeding through a rectifier 2, supplies a current to the inverter with a magnitude corresponding to the current rating of the rectifier to be tested, the voltage of the direct voltage source being at least one order of magnitude lower than the rated voltage of the rectifier. The oscillation circuit is so arranged that the amplitude of the oscillation voltage, when the inverter operates with a frequency corresponding to the natural frequency of the oscillation circuit exceeds the desired test voltage. After an extended test period in this circuit, the rectifier is taken to pieces to determine the state of wear of the various parts. The arrangement is such that the oscillation circuit has a lower frequency than the commutation frequency of the inverter, so that the commutations of this circuit never take place at zero current, because the current in the oscillation circuit is never in phase. An operating frequency greater than the mains frequency should preferably be used for the inverter operation, but should be less than 250 c/s.

Abstract: 607,841. Vehicle couplings. DAVIES, A. R. Feb. 12, 1946, Nos. 4423 and 16795. [Class 103 (v)] A tractor-trailer coupling comprises a fixed jaw 2, Fig. 1, integral with an angle 1 attached to a depending leg on a trailer and a hinged jaw 14 pivoted at 17 to the jaw 2, the two jaws being clamped together by a bolt 6. The jaws are provided with semi-circular recesses 19, 20 which grip a transverse rod 21 attached by brackets 23, Fig. 4, to the rear bumper 24 of a car, the attachments being duplicated on each side of the vehicles. The bolt 6 passes through holes in the ends of the jaws and is provided at its end with a pivoted tongue 11 which is aligned with the bolt when the latter passes through the holes in the jaws and is then turned laterally as shown in Fig. 1 to form an abutment when tightening the bolt. The bolt is prevented from rotation by a flat 9 thereon and a pin 10 which passes through the hole in the jaw 2, a spring 8 around the bolt maintaining the latter in the raised position. A grub-screw and keyway may replace the flat 9 and pin 10. In Fig. 5, the pin 30 has flat sides and is pivoted between bifurcations 28 at the end of the jaw 2, the pivot pin 37 engaging in a slot 36 in the bolt. The lower end of the bolt passes between bifurcations 38 in the jaw 14 and is provided with a T-head to engage in a recess 39 in the underside of the jaw, the two jaws being pressed together by a spring 33 which is compressed by the action of a cam surface 29 when the bolt is swung from the disengaged to the engaged position. In a modification an L-shaped bolt, under the control of a spring, is adapted to engage in a recess in the pivoted jaw in the closed position and to be pushed down and rotated to clear the jaw for uncoupling purposes. The coupling may be built up of welded parts.
