IPC: G21C17/04
Filed: 1965-11-12
Abstract: 1,156,342. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 3 Nov., 1966 [12 Nov., 1965; 27 April, 1966], Nos. 48260/65 and 18534/66. Heading G6C. In a fast nuclear reactor fuel element sheath failure indicating system, delayed neutron emission from fission products is employed, e.g. from I 137 and Br 87. The delayed neutrons possess higher energies than the core neutrons, having been subjected to less scattering, and are distinguished thereby. A sheath failure causes the injection of fission products into the liquid sodium reactor coolant which is monitored. A neutron detector is mounted at the outer surface of the pressure vessel and a part of the coolant flow is directed into a zone at the inner surface of the vessel adjacent to the detector. In one embodiment, an array of detectors provide indications of the core section where a sheath failure occurs and of the total degree of failure so as to initiate reactor shut-down. The neutron detectors employ BF 3 , are embedded in solid hydrogenous moderator, and are subjected to collimated neutron beams by shielding. Filters absorb core neutrons.

Title: Detection of emanations from materials and measurement of the quantities of said materials
IPC: G01J3/00
Filed: 1949-07-18
Abstract: 663,978. Determining physical qualities of materials. HIERONYMUS, T.G. July 18, 1949, No. 18866/49. Class 37. [Also in Group XL (b)] Elements are identified and combinations of elements are analysed by the detection and analysis of radiations emanating therefrom. A unit 10 includes a coil 12 arranged to pick up radiations from a substance 14, the elements contained in which are to be detected. Instead of employing the coil 12 a wire 20 may be directly connected to the substance 14 or may be terminated in an electrode in proximity to the substance so as to pick up the radiations therefrom. A wire 18 may be earthed or connected separately to the substance 14 or terminated in another electrode placed near this substance. An analyser 16, tunable to the specific radiation to be detected, comprises variable condensers 22, 24 and a ray-refracting device consisting of two electrodes 32, 38, a passage-way 36, and a glass, quartz, or like prism 28. The electrodes 32, 38 may be of aluminium, brass, copper, or other conductor. The passage-way 36 is formed between a pair of optically opaque insulating members and directs the radiations on to one face of the prism 28. The electrode 38 is movable adjacent to a scale 31, its position being indicated by a pointer 78. The analyser 16 is connected through a variable resistance 40, transformer 58, amplifier 70, and transformer 74, to a detector 72. This comprises an electrical conductor coated with a material which, under the influence of energy flowing through the conducting portion, changes its surface tension or viscosity and thus produces a greater drag or resistance to the movement of the operator's hand or fingers over it. One construction consists of a metal plate covered with a sheet of plastic or coated with lacquer. Alternatively the detector may comprise a sheet of plastic with a coil similar to the coil 12 adjacent thereto and connected to the transformer 74. The prism 28 may be replaced by a lens, the electrode 38 being movable in a straight line along its optical axis adjacent to a straight scale. The electrode 38 is adjusted until it coincides with the ray deflected by the prism or with the focal point of the rays passing through the lens, this point being determined by the greatest drag experienced at the detector 72. The variable condenser 24 is then similarly manipulated to obtain a setting where the drag at the detector 72 is a maximum, and the electrode 38 is readjusted for a final position. The atomic weight of the element corresponding to the position of the electrode 38 as indicated on the scale 31 is then read off from a reference chart. The resistance 40 is then adjusted to the maximum value which will not interrupt the reactions manifested at the detector 72, its value being a measure of the intensity of the radiations.

Filed: 1922-07-10
Abstract: 205,171. Bautzner Industriewerk Akt.- Ges., and Bornschein, G. July 10, 1922. Rotary machines ; tripping-arrangements.- The cylinders of printing machines are mounted in two eccentric bushes arranged one within the other, each bush being capable of separate handmanipulation so that by combining the two rotations the bearings can be moved in straight or curved paths. Means for locking the bushes in their adjusted position, and for withdrawing the bearing-spindles so as to allow the cylinders to be removed are also described. The ball bearings 13 of a cylinder 8 are supported by a spindle 7 mounted eccentrically in a bush 5 which is eccentrically mounted in a bush 2 mounted in a recess in the frame 1 of a printing-machine. The bush 5 is formed with a conical part 4 fitting in a similar recessed part of the bush 2 which is split for a length which is at least equal to the part 4, and a nut 6 which screws on the outside of the bush 5 moves the bush 5 longitudinally relatively to the bush 2 in order to force out the end of the bush 2 to lock the bushes in adjusted position. To adjust the cylinder, the nut 6 is moved to free the bushes, and the bush 2 is turned by a knurled boss 14 and the bush 5 by a wheel 9 which is pressed by a spring 12 to cause a projection 10 to engage a notch in the bush 5. The wheel 9 is connected by a pin-and-slot to spindle 7. If the wheel 9 is moved axially to the right it can be rotated without actuating the bush 5. By this means the spindle 7 can be rotated in a counterclockwise direction relatively to bush 5, and a pin 17 on it withdrawn into a bayonet slot 15 so as to free the bearing 13 from the spindle 7 and allow the cylinder to be withdrawn, a bracket 16 being provided to rest the bearing 13 on during insertion or removal of a cylinder.
