Title: Improvements in or relating to rolls for rolling mills

Title: Improvements in or relating to ionisation chamber circuits
Inventor: COX RAYMOND JOHN
IPC: G01T1/185
Filed: 1959-04-10
Abstract: 893,907. Radiation detecting systems. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 5, 1960 [April 10, 1959], No. 12297/59. Class 40(3). The present invention seeks to avoid the problems inherent in the measurement of small direct currents derived from ionization chambers to which a steady D.C. polarizing potential is applied. According to the invention the polarizing potential for an ionization chamber is provided by an A.C. generator and the A.C. current passing is amplified and fed to measuring apparatus. In this, phase-sensitive means are used separating the in-phase or anti-phase and quadrature components. The former is used to give an indication of radiation flux and the latter to check the functioning of the system. The A.C. polarized chamber may be used in a bridge circuit. In one arrangement it is proposed to apply to a chamber an A.C. polarizing potential exceeding in amplitude the saturated condition for the chamber. The output in such a case is rich in harmonics and substantially independent of the peak amplitude of the applied potential. Its fundamental component may be taken as proportional to the radiation (such as neutron) flux. Another possible arrangement is to apply a very small alternating polarizing potential and this gives an almost pure sinusoidal output proportional in amplitude to the potential over a limited range. The fundamental component of the output is in this case approximately proportional to the square root of the radiation flux and there is a low capacitive current component. The resistance of electrode coatings of boron may considerably affect the output current when low potentials are applied. As the resistance of the coating is not stable it is preferred to reduce this to a low value by depositing a metal coating in a boron coating which is absent from a plurality of small areas of the electrode so that the deposited coating is in good electrical contact with the electrode. In a reactor trip circuit embodiment using a polarizing potential of one volt or less at a frequency of 60 c/sec. the chamber 1 is supplied with this potential from generator 2 of push-pull type through variable resistor R. This resistor is set to provide a null output at 3 when the inphase current component reaches a predetermined level corresponding to a given neutron flux level. The output of amplifier 4 is fed to phase-sensitive meter 5 which indicates the in-phase or anti-phase component amplitude and has a scale reading in both directions from zero. Phase sensitive relay 6 is also connected to the amplifier output, is responsive to the quadrature current component and controls an alarm device. A further amplifier 7 and relay 8 is provided to exercise a control function if the neutron flux exceeds the given value.

Abstract: 711,353. Valves. SPENCER, D. L., and SPERRY GYROSCOPE CO., Ltd. May 16, 1952 [May 25, 1951], No. 12326/51. Class 135 In a pressure regulating valve having a channel leading from the valve outlet so that the outlet pressure acts to move the movable valve element towards closure, the said outlet pressure is applied to the movable valve element through an auxiliary movable member whose movements are hydraulically damped and a resilient coupling. As shown, the valve comprises a movable valve element 2 controlling an inlet passage 1 and connected by a spring 8 to an auxiliary movable member 12, comprising a piston 6 subjected on its upper face to the outlet pressure transmitted through a channel 4 and a damping piston 7. The damping piston 7 has small diameter holes 9 therethrough so that before the auxiliary member 12 can move to adjust the position of the valve element 2 pressure fluid must be transferred from one side of the piston 7 to its other side which prevents sudden movements of the valve element and renders it substantially stable. Instead of a poppet valve as shown, the movable valve element may comprise a piston valve in which case the spring 8 would bear at its lower end on the top face of the piston valve.

[Class 60] A chuck for holding a face grinding-wheel comprising a body wherein a face grinding-wheel is held by a split tapered ring lined with fibrous material and compressed to clamp the wheel by a screwed collar, has means whereby the grinding- wheel is locked against axial movement comprising interengaging portions on the wheel and ring. The chuck body a has an externally screwed boss b carrying an adjustable back-plate e, and has also a flange f with an internally tapered surface g and an external screw-thread receiving a flanged collar h and a locking ring k. A split tapered ring m, which may be in several portions, is located in the tapered flange f and is lined with fibrous material n, which engages the outer surface of a grinding-wheel p when the collar h is screwed up, and in order to prevent axial movement of the wheel p the ring m has a lip r to engage one of a number of grooves s in the wheel p. As the wheel wears, another groove s is utilized, the back-plate e being adjusted to engage the inner end face of the wheel ; the lip r may be replaced by projections which engage a spiral groove in the wheel p. In a modification, the boss b and the backplate e are omitted, and the grinding-wheel may be solid. A number of chucks carrying the grinding-wheels may be secured in a circle to a face-plate to form the equivalent of a segmental type grinding-wheel.
