Title: Gripping device,particularly for handling nuclear reactor fuel elements
Inventor: LECLERE BERNARD
IPC: G21C19/105
Filed: 1963-09-25
Abstract: 971,438. Article engaging devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 25, 1963 [Sept. 26, 1962], No. 37797/63. Heading B8H. [Also in Division G6] A fuel element grab comprises two parts A, B normally connected by a coupling arrangement C, the part A being suspended by a hoist cable 10 and the part B having jaws 17 which automatically move to grip an internal surface of a fuel element upon lowering of the grab on to the element. Should the part B become jammed so that it cannot be removed from the reactor then by exerting sufficient tractive force on the cable the coupling arrangement C is released enabling the part A to be withdrawn and subsequently lowered on to another part B to which it becomes automatically connected by the arrangement C. The part B is constituted by a sleeve 12 normally surrounding a sleeve 4 constituting the part A. The coupling arrangement C comprises an annulus 32 housing locking balls 30 and elastically supported between two springs 36, 38, the other ends of the springs engaging abutments 40, 44 respectively on the sleeve 12, the spring 36 being several times stiffer than the spring 38. A thickened portion 24 of the sleeve 12 normally holds the balls 30 in a groove 34 in the sleeve 4, thereby connecting the parts A, B. Should the part B become jammed then sufficient tractive force is applied to the cable 10 to compress the spring 36 so that when the balls reach shoulder 26 they move outwardly from the groove 34 and permit withdrawal of the part A. On lowering the part A on to another part B, a shoulder 54 engages the balls and moves the annulus 32 downwards until a shoulder 28 is reached, whereupon the annulus remains stationary. In this condition the spring 38 is compressed so that when the groove 34 arrives opposite the balls the latter move into the groove and the spring returns the annulus to the Fig. 1 position when the weight of the part A is removed from the spring. Brake arms 46 pivoted on the sleeve 12 and biased by springs 50 move outwardly to engage a channel wall and prevent dropping of the part B when the part A is removed, the arms 46 being retracted by a ramp surface 52 on the part A when the latter is moved into a part B.

Abstract: 1,223,810. Measuring force electrically. GENERAL ELECTRIC CO. July 29, 1969 [Aug. 9, 1968], No.38039/69. Heading G1N. [Also in Division G3] A transducer for measuring force comprises two pairs of semi-conductor strain gauges mounted so that each pair is stressed oppositely by the applied force, each pair being connected in a Wien bridge oscillator circuit so that the strain gauge resistance determines the oscillator frequencies, which are therefore varied differentially by the force whose magnitude is indicated by the frequency difference. In one embodiment, Fig. 2, for measuring acceleration, a constant stress cantilever beam 15 of n-type single crystal silicon is rigidly secured at one end to a support 16 and carries a mass 17 at the other end. Two pairs of strain gauges R5, R6 and R7, R8 formed by elongated strips of p-type silicon are formed on the opposite faces, each pair being connected in a Wien bridge oscillator circuit, Fig. 1, (not shown), initially adjusted to the same resonant frequency. When subjected to acceleration normal to the plane of beam 15, the resistances of the strain gauge pairs vary oppositely, producing a frequency difference between the oscillators which is measured at mixer 13. Another embodiment, Fig.3, for measuring weight comprises live vertical load columns 20, 21 of single crystal silicon, mounted between a horizontal base 22 and load distributor 23, the strain gauges R5-8 being formed on one column 21 in perpendicular directions so that they are stressed oppositely by an applied weight. The remaining circuitry may be formed as a monolithic integrated circuit mounted on column 22.

Abstract: 1470778 Linkwork; ratchet mechanisms LUCAS INDUSTRIES Ltd 12 Aug 1974 [11 Aug 1973] 38158/73 Headings F2K and F2Q In a step-by-step indexing mechanism, which may be used for positioning test thermocouples in a gas turbine engine, a moving arm 10 is pivoted at 11 to a fixed plate 12 which carries a series of apertures 21 spaced along arcuate guide grooves 20, and arm 10 carries a pneumatic actuator 22 having a piston rod 24, Fig. 2, which can be caused to enter a chosen aperture 21. An L-shaped member 13, guided by projections 18 in the grooves 20, has a slot 15 engaging a pin 14 in the arm 10, permitting limited relative movement determined by an actuator 16 with a piston rod 17, and carries an actuator 23 having a piston rod 25 which also can be caused to engage an aperture 21. From a position in which rod 24 is engaged in an aperture, thereby operating a limit switch 37, with rod 25 disengaged and operating a switch 41, and with rod 17 retracted causing switch 26 to be operated, the procedure for moving the arm 10 one step forward is as follows. First, actuator 16 causes rod 17 to be fully extended and operates switch 27, secondly, actuator 23 causes rod 25 to engage a fresh aperture 21 and operates switch 40, thirdly, actuator 22 causes rod 24 to become disengaged and operates switch 36, fourthly, actuator 16 causes rod 17 to be retracted and again operates switch 26, when finally rod 24 becomes engaged to lock arm 10 into the new position, one step forward. Each actuator is controlled by a reversing valve which responds to two solenoids, e.g. actuator 22 is controlled by valve 30, with solenoid 34 energized to extend rod 24, and solenoid 35 energized to retract rod 24. Six bi-stable circuits, connected to the six actuator limit switches, dictate the stepping sequence, which runs forwards until limit switch 50 is reached, when automatic reversal of stepping sequence prevails until switch 51 is reached.

Title: Improvements in or relating to circuit arrangements for comparing pulses
IPC: H04N5/12
Filed: 1957-12-12
Abstract: 874,208. Phase discriminators. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 12, 1957 [Dec. 15, 1956], No. 38664/57. Class 40(5) In a circuit for comparing the phase of a pulse e.g. a synchronization pulse in a television system, with respect to a further pulse, e.g. a pulse derived by differentiation of the line flyback pulse, the synchronizing pulses are applied via a capacitor 2 to the control grid of a valve 3, the resulting output pulse being differentiated at 5 and the negative spike being suppressed by a rectifier 6. The positive spike is applied to differentiating circuits 7, 9 and 8, 10, respectively, to provide two similar outputs each comprising a sharp positive pulse directly followed by a sharp negative pulse. A further pulse, derived from the line flyback pulse and having an edge which slopes evenly between a positive and corresponding negative value, is applied to the junction of capacitors 13, 14. The time constants are such that through the action of the diode 11 a voltage is set up across the capacitor 13 which corresponds to the peak value of the sum of the positive portion of the output from the circuit 7, 9, and of the pulse derived from the line flyback, Similarly, the diode 12 provides a voltage across the capacitor 14 which is equal to the peak value of the sum of the negative going portion of the output from the circuit 8, 10, and the pulse derived from the line flyback. If the pulses derived from the circuits 7, 9 and 8, 10, respectively are equally spaced on either side of the zero point of the pulse derived from the line flyback the voltages on the capacitors 13, 14, will be equal, but in the case of phase deviations from this point the voltage will become unequal in a sense, determined by the direction of the deviation. The resultant voltage appearing at the junction of the resistors 15 and 16 gives a measure of the relative phase variation and may be smoothed by a capacitor 17 and utilized to control the line oscillator.
