Abstract: 869,647. Nuclear reactor control rods. HAWKER SIDDELEY NUCLEAR POWER CO. Ltd. Nov. 11, 1959 [Nov. 11, 1958], No. 36195/58. Class 39(4). A nuclear reactor is provided with a control rod movable upwardly and downwardly, projections carried by and extending laterally from the control rod and movable about the axis of travel of the control rod, and for each projection a support forming part of or secured to the fixed reactor structure, a fixed first profile to guide the projection during upward travel to a position for lowering on to the support, and a second fixed profile to guide the projection during upward travel to a position for lowering past the support. The control rod 1 shown in Fig. 1 is provided with a pair of lugs. 2 projecting from diametrically opposed points of a spindle 4 set in hardened conical bearings 5 set in the control rod. The bearings prevent rotation of the spindle from exerting any appreciable torque on the rod and the use of a tape 13 for suspending the rod increases its resistance to rotation: Above the normal operating position of the rod is fixed a collar (not shown) provided with two profiled passages as shown in Fig. 3 for the passage of the lugs 2. As the control rod is raised each lug will pass through its associated passage until it encounters a profile 7 which guides it to the position A; if the rod is then lowered the profile 8 guides the lug to a position B where the rod is securely supported by the lugs and the suspension mechanism may be detached for inspection or maintenance. If the rod is raised from this position each lug is guided by a profile 10 to a position D from which it can be lowered back through the passage or raised to position C where it is free for further upward travel.

Title: Means for measuring the superimposed oscillation of part of a rotating member
Inventor: ECCLES EDWARD STUART
IPC: G01H1/00
Filed: 1960-10-21
Abstract: 1, 009, 979. Measuring torsional oscillations electrically. BRISTOL SIDDELEY ENGINES Ltd. Nov. 10,1961 [Oct. 21, 1960], No. 36208/60. Heading G1N. Apparatus for measuring torsional and axial oscillations of a rotor while it is rotating comprises a magnetic or electrostatic member attached to the rotor and a series of conductors in a locally-associated stator which co-operate with the rotor member to produce an alternating voltage whose frequency is primarily dependent on the rotor speed, but is modulated in accordance with the oscillations. In one embodiment (Fig. 1), one rotor blade 13 of an axial flow air compressor has a magnet 14 in its tip, co-operating with a zig-zag conductor system 17 (Fig. 4) on the surface of the stator 10, whose conductors 18 are connected in series between end conductors 18a. When the compressor is rotating the flux magnet 14 cuts the axially located conductors 18 to produce an alternating voltage between conductors 18a, whose frequency is indicative of the angular velocity of the rotor blades 13, oscillations of the rotor causing the basic frequency to be modulated correspondingly. The conductors 18 may be parallel to the axis of rotation, or inclined at 45 degrees to the rotor axis to provide indications of axial vibration, or two perpendicular series of conductors may be used, each inclined at 45 degrees to the rotor axis. The apparatus may be used to measure vibrations at different positions along the rotor blades. In an electro-static embodiment (Fig. 7) the stator conductors 62 are continuous and the rotor carries an electrostatic electrode 60, the capacity between them varying cyclically as the machine rotates. This varying capacitance Cv (Fig. 10) is connected in series with a fixed capacitance C across a battery V, and the voltage across capacitance C has a fundamental frequency indicative of the speed of rotation, and a modulation characteristic indicative of the rotor oscillation. The fixed conductors 62 may be duplicated to form a differential capacitor with electrode 60 for use in a bridge circuit. A combined electrostatic and electromagnetic arrangement may be used (Fig. 12, not shown). In a further embodiment (Fig. 13) for use with roller bearings 69 in a ring housing 67, 68, an axial magnet 72 induces an E.M.F. in zig-zag conductors 71 whose frequency determines the speed of rotation of the roller 69 about the main axis, and an offset magnet 70 induces a further E.M.F. enabling the speed of rotation of the roller about its own axis to be determined.

Abstract: 1,176,585. Impelling tools. GARDNER DENVER CO. 1 Aug., 1968 [18 Dec., 1967], No. 36866/68. Heading B4C. A pneumatically operated percussion rock drill including means for supplying cleaning water to the bore hole comprises a compressed air throttle valve 28 and a water pressure regulating valve member 58 controlled by the compressed air. In operation compressed air passes via bore 80, annular passage 82 and bore 84 into chamber 62 to act on and displace a piston 64 to which the valve member is attached. Removal of the valve member from its seat 44 enables water to flow from conduit 86 via bore 88, passage 90, and apertures 92 to a water pipe 48, and via bore 94 in the valve member to chamber 65. The water in chamber 65 acts on the piston to move it against the force of the compressed air until a balance is reached. When the throttle valve is closed the bore 80 communicates via slot 100 with the atmosphere. The valve regulates the cleaning water supply pressure automatically proportional to the drill operating pressure and prevents water leakage to the drill operating mechanism in the event of leakage of the seal 46.
