Abstract: 953,233. Shearing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 3, 1962, [July 10, 1961], No. 24834/61. Heading B3W. [Also in Division G6] A cable cutter for cutting the thermocouple leads of reactor fuel elements comprises an elongated body having a longitudinal aperture therethrough, remotely controlled cutting means at one end of the aperture, clamping means for the cable and support means for the body at the end remote from the cutting means. The cutter body 1 has a central bore 3 and a longitudinal aperture 2. Within the bore 3 is a ram 10, one end of which carries seals 16 and operates in a counterbore 6. Pneumatic pressure can be applied to the chamber on either side of the seals. The other end of the ram has a forked end 17 and a cam slot 18 in which runs a pin 22 which also passes through a lever 20. The lever pivots about a pin 21 and has a tip 26 which co-operates with a member 28 to shear a cable within the aperture 2. An inclined face 19 on the ram engages a ball 37 and a plunger 36 and clamps the cable while it is being cut. At the forward end of the body are two lobes 33 which engage a transverse arm of the fuel element end fitting and correctly orientate the cutter with respect to the element. A duct 52 in the body is connected to a source of pneumatic pressure and leads to a bore 44 in which slides a plunger 45 having a waisted portion 49. The cutter is threaded on to the thermocouple cable and lowered on to the fuel element with pressure applied to the duct 52 and to the chamber 42 on the forward side of the seals 16. When the end 47 of the plunger 45 abuts the fuel element it is pushed inwardly against a spring 48 and connects the duct 52 to the aperture 50. The resultant drop in gas pressure is indicated by a gauge at the charge face and indicates that the device is correctly located. Gas pressure is admitted to the chamber 39 and operates the cutter. Specification 953,232 is referred to.

Filed: 1950-10-25
Abstract: 682,903. Infra-red gas analysis. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Oct. 25,1950 [Oct. 25, 1949], No. 26051/50. Class 40 (iii). In infra-red absorption analysis of a mixture of gases in which one or more cyclically and simultaneously interrupted beams is passed through an absorption cell, through which the fluid mixture under test is passed, to a detector containing the component being tested for, the pressure pulses produced in the detector being converted into electrical pulses, each of the detector cells contains a component of the fluid mixture different from that in the other detector cell or cells. As shown, twin beams of radiation from sources 3, 5 simultaneously chopped by a motor driven chopper 40 pass, one through a filter cell Z and the other through a cell containing a neutral gas N. Both beams then pass through a sample cell 48 through which the gas mixture under test circulates to one of two detector cells 15, 16, one containing one of the gases to be discovered diluted with nitrogen while the other may contain the rest of the gases in the mixture also diluted with nitrogen. At the bottom of each detection cell is a deformable diaphragm 49, 59 which forms with one of fixed electrodes 52, 54 a condenser, the capacity of which varies in response to the periodic expansions of the gases in the detectors. One of the deformable diaphragms is held at a negative voltage while the other floats at a positive voltage determined by the output of a D.C. amplifier 70. Electrodes 52 and 54 are joined together and feed an A.C. amplifier 57, the output of which is fed via a transformer 61 and a commutator 67 driven in synchronism with the chopping disc to the D.C. amplifier, the output of which thus depends on the error signal between the two detectors. This output varies the potential of diaphragm 49 until output reaches the A.C. amplifier and controls an instrument 71 to indicate the proportions of the two gases, samples of which are in the two detecting chambers. The balancing arrangement and the two detectors are not necessary but if several components are to be determined, several detectors and chopped beams may be employed. In the simpler arrangement of Fig. 1 in which the output of the two cells controls a recorder indicating the ratio of the proportions, the same output may be used to control the flow in a pipe carrying the stream being analysed. Vapours may be analysed by bubbling a non-absorbing gas through the vaporizing liquid and delivering through this pipe.
