Patent GB-2270733-A (GB)
Title: Spring support
Inventor: SALTER ANTHONY JOHN
IPC: F16L3/205
Filed: 1992-09-22
Abstract: A spring support suitable for supporting pipes subject to movement in use has its spring housed in a body 1 and lockable against movement by a locking element 18, 19. The locking element moves with the spring, on a piston 2 supported by the spring, and is movable relative to the spring between operative and inoperative positions. In the operative position the element 18, 19 engages with locating means 39 fixed with respect to the body and in the inoperative position it is released to leave the spring free to move. In the illustrated embodiment the locating element is a rectangular plate member pivotable between the two positions. The element is free to move along an opening 8 in the body when in the inoperative position, and is engaged at its ends in locating recesses 39 at opposite sides of the opening in the operative position (Fig. 9). An indicator 41 on the locking element registers with a scale 42 on the body to show deviation of the spring under applied loads. Other embodiments of locking element and locating means are described. <IMAGE>

Title: Joints and jointed structures
Inventor: SAUNDERS ROGER JOHN LAVERS
IPC: E06B9/262
Filed: 1993-01-28
Abstract: A joint form which can be formed integral with structural members, comprises two joint members. Each joint member comprises a reference portion A or B and a resilient connective portion which forms a mouth. The connective portion is resiliently deformed to nest at least partly around or within the resilient connective portion of another similar joint member. Joint members may be orientable relative to each other, forming a hinge, or latched or bonded to each other in a fixed position. The resilient shape of the connective portion enable it to be assembled with one or more similar connective portions, and tubes. The joint may be formed in any suitable material or manner. In one example, opposite edges of PVC sheets are thermoformed to the required shape. Four sheets may then be assembled to form a box structure. <IMAGE>

Patent GB-2314619-A (GB)
Title: Radioactive iodine monitor
Inventor: OLIVER MARTIN JOHN
IPC: G01T1/178
Filed: 1996-06-29
Abstract: Radioactive iodine monitor apparatus and method enable continuous measurement of gamma radiation from isotopes of iodine. The air or gas stream to be measured is passed through an adsorbent material such as carbon to remove iodine compounds. A radiation detector, designed for optimum response to low energy gamma radiation, monitors emissions from the adsorber. Signals from the detector are amplified and analysed by evaluation electronics to separate wanted iodine signals from unwanted signals due to background radiation and other interfering isotopes. A central processor uses the results from one or more compensation channels to correct for crosstalk in the Iodine channel. The final result corresponds to either the total amount of the iodine isotope or the concentration. The results can be stabilised by sensing the temperature of the detector assembly and controlling the detector to maintain accuracy under conditions of varying temperature.

Title: Arc welding or cutting equipment; reducing interference
Inventor: DANJO KENZO
IPC: H04B15/02
Filed: 1996-12-04
Abstract: A power supply for an arc welder or cutter generates a DC output at terminals 26N, 26P by means of an input rectifier 12, a high frequency inverter 18, 20 and an output rectifier 22, the inverter 18, 20 being controlled by a circuit 60 which also controls operation of a high frequency pilot arc generator 34, 36 under the command of a switch 46 on the welding/cutting torch 30. A bypass capacitor 38 is connected to output terminal 26N and to the junction between a smoothing reactor 34 and an adjacent end of an output transformer 36 of the pilot arc generator, such connections being made directly, that is without using connecting lines which could otherwise radiate high frequency noise. A centre-grounded series circuit of capacitors 42, 44 is similarly directly connected to terminal 26N and transformer 36. Switch 46 is connected to terminals 48, 50 of a switch connector (47, Figs.2,3) on a housing (68) of the power supply, and further capacitors 52, 56, 58 are similarly directly connected to connector terminals 48, 50. A common-mode noise rejecting reactor 62 is disposed between the switch connector (47) and the control circuit 60. The arrangement of directly connected capacitors and the reactor 62 prevents high frequency noise causing erroneous operation of a CPU or programmable logic device (PLD) in the control circuit 60. An earthed shield case (71, Fig.2) encloses pins of semiconductor devices (64) on a printed circuit board (66) of the control circuit 60.

Title: Wheel balancing apparatus using positive feedback to cause torsional instability
Inventor: FARAHNAK NADER
IPC: G01M1/04
Filed: 1997-04-03
Abstract: A machine for detecting the state of unbalance of a "rigid" wheel in 2 planes has - as its central component - an arbour 1 designed to be torsionally flexible but laterally rigid. The arbour 1 carries a wheel at each end - one of these being the trial wheel 3 which is required to be balanced and the other being a well-balanced reaction inertia 6. The arbour is coupled to a motor 9 or torsional actuator which is capable of exerting small torques on it in such a manner as to excite the first torsional resonance. Instability of a positive-feedback control system around the motor is used to cause the torsional resonance to become excited. When the arbour is undergoing substantial torsional oscillations, the effect of significant instantaneous angular accelerations combined with the presence of unbalance causes forces to exist on the arbour from the wheels. These forces cause the bearings which support the arbour to move (or deform) and the movement (or deformation) is detected and used to deduce the unbalance.
