Title: Method of Continuous and Automatic Measurement of the Gamma-Ray Emission of a Solution and a Device for the Application of said Method
Inventor: PATIGNY PIERRE
IPC: G01T7/02
Filed: 1967-04-05
Abstract: 1,164,739. Measuring radioactivity of a liquid. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 5, 1967 [April 5, 1966J, No.15716/67. Heading G1A. The radioactivity of a liquid containing fission products is measured by a two-path photo-electric system in order to compensate for errors due to adsorption of fission products on the walls of the measurement cell. The liquid 2, which is y-ray emitting, is passed through a tank 4 having two parallel walls 5, 7, but of changing depth. Lead shielding is provided all round the tank and the shielding wall 6 is provided with collimator apertures 8, 10 so that scintillation counters 12-16 and 14-18 can respectively view volumes v 1  and v 2  of the liquid, and areas s 1  and s 2  of the top y-ray transparent wall 5 on which fission products are adsorbed. (Adsorption takes place on the bottom wall 7 but this is arranged to be distant engouh from the scintillators not to be detectable). Volumes v 1  and v 2  are in a fixed ratio p 1  and areas s 1  and s 2  in a fixed ratio p 2  different from # 1 . An equation is derived for the activity A u  of the liquid as A u  = 1/V 2  (N 1  - p 2 N 2 ) / p 1  - p 2 )   where N 1  and N 2  are the counts obtained in a certain time interval by counters 20, 22. For simplicity, the volumes viewed by the detectors are arranged to be equal (v) and the areas s 1  and S 2  in the ratio 1:2 so that the activity per unit volume is obtained as A u  = 1/V(2N 1  - N 2 ). Thus by feeding the outputs of counters 20, 22 to a subtraction circuit 24, the value N 1  - N 2  is obtained. Addition of the output of counter 22 to this in adding circuit 26 gives an output which can be calibrated to equal the activity per unit volume.

Abstract: 1,223,154. Digital transmission systems. INTERNATIONAL STANDARD ELECTRIC CORP. 4 April, 1968 [10 April, 1967], No. 16160/68. Heading H4P. [Also in Division G4] A digital data receiver includes correlators for detecting each of n orthogonal signals. The correlator outputs are decoded to provide a marking on one of 2n outputs. In the embodiment described, Fig. 2 (not shown), a 3-bit serial signal is received in a time T, the bits being regarded as orthogonal signals. The signal passes to each of three correlators in which it is multiplied with signals 100, 010, 001, respectively. The multipliers feed integrators connected to threshold circuits, and the three threshold circuits thus develop a 3-bit parallel bit signal corresponding to the received signal. The parallel bit signal passes to a gating circuit which energizes one of 2<SP>3</SP> = 8 generators which are sampled successively.

Title: Improvements in or relating to safety devices for lift and hoist cages and the like
IPC: B66B5/24
Filed: 1946-05-28
Abstract: 612,654. Catch gear for lift cages. BARTON, R., and ADLER, P. May 28, 1946, No. 16263. [Class 78 (iii)] In a safety device for lift cages, of the kind in which frictional clamping devices are first actuated automatically by an arm on its release by breakage of the hoisting cable so as to cause the device to loosely grip guide ropes or rods sufficiently to retard the downward sliding of the device on the guide ropes, such devices being thereafter further automatically actuated by means connected to the cage on the descent of the cage away from the clamping devices to increase their grip relatively gradually to prevent further downward slipping of the cage, the clamping devices are actuated by screw means. The cage is suspended by chains 1 from a member 2 on the end of the hoisting cable and is guided by cables 3 which pass through blocks 5 which normally rest on the blocks 4, and each of which consists of a fixed vertical guide engaging member 6 and a horizontally movable clamping member 7, operated by one end of one of the threaded spindles 9 to each of which is mounted, by means of a ratchet- and-pawl mechanism, a weighted arm 10. Catches 1, 8 which normally engage notches 16 in the cross-member 17 on the top of the cage, are together with arms 15 solidly connected to the spindles 9, and the arms 15 are flexibly connected to the cross-member 17 by loose chains 19. On breakage of the hoisting cable, the connecting member 2 falls and allows the arms 10 to swing downwards, rotating spindles 9 which force clamping members 7 into engagement with the cables and at the same time disengage the catches 18 from the notches 16 allowing the member 17 to drop away from the blocks 5 until checked by chains 19 which now carry the whole weight of the cage, and the resultant force transmitted through the spindles 9 to the clamping members 7 finally brings the cage to rest. In a modification, guide rods are provided instead of cables.

A control device for a pressurized gas-cooled nuclear reactor comprises a neutron absorbing body 5 housed within a neutron absorbing body 4 in a container 3 in a vertical channel in the reactor core, and means for releasing the body 5 so that it falls under gravity, thus increasing the neutron absorption capacity of the device. In the device shown, on a sudden reduction of coolant gas pressure, gas escapes more quickly through holes 22, 23 than through hole 21, thus creating a pressure difference across diaphragm 11 which moves and lowers plug 13, allowing boron steel shot 5 to fall out of boron steel tube 4 into tube 18. Other neutron absorbing elements referred to are cadmium, mercury and rare earths.
