Title: Thermal Regenerator Matrices
IPC: F28D19/04
Filed: 1967-08-03
Abstract: 1,156,348. Thermal regenerators. GENERAL MOTORS CORP. 3 Aug., 1967 [8 Dec., 1966], No. 35746/67. Heading F4K. The matrix 11 of a radial-flow, rotary, thermal regenerator includes an annular, drum-shaped body of porous material 22 having imperforate end rims 21, said body comprising a ring of blocks 27, each of which has a structure which defines a multiplicity of substantially parallel pores extending generally radially with respect to the axis through the drum, circumferentially adjacent pairs of blocks forming a marginal area at the junctions 29 of the blocks in which the pores of at least one of the blocks terminate against the adjacent block, thus providing a dead zone in the matrix which does not permit flow therethrough. The structure of the blocks is made by laying up alternate layers of thin flat ceramic sheet 25 and a corrugated ceramic sheet 26 (see Fig. 5, not shown), the resulting porous material being then fired to provide a unitary slab. As shown in Fig. 4, the matrix is usually formed from two rings of generally parallelogram-shaped blocks 27, the rings abutting along a central plane 28 to form a chevron pattern, with the joints 29 between circumferentially adjacent blocks skewed so that the dead-zones are distributed evenly around the circumference of the matrix.

Title: Electric circuit closing device, especially for use in the testing of switches
IPC: G01R31/04
Filed: 1955-12-16
Abstract: 785,903. Heavy-current switches; pneumatic actuation of switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Dec. 16, 1955 [Dec. 20, 1954], No. 36092/55. Class 38 (5). A circuit-closing device for switchgear testing has a movable contact 11 operated by a piston 9 which immediately before the closing operation is subjected to a resultant pressure acting in the closing direction, but is held in the open position by a holding magnet 18 until the magnet is demagnetized by a releasing impulse. In the arrangement shown both compartments 3, 4 of a tank 1 are filled with compressed air and the contact 11 is biased to the open position by a spring 26. To close the contacts, the cylinder 7 is opened to atmosphere by a valve 22 so that the pressure in the compartment 4 acts only on the lower face of the piston 9. Then a demagnetizing winding (not shown) of the holding magnet 18 is energized so that the magnet releases an armature 25 and the piston 9 is then moved by the air pressure against the bias of the spring 26 to close the contacts 11 ... 13. To open the contacts, the cylinder 7 is connected to the compartment 4 by the valve 22 so as to equalize the pressure acting on both sides of the piston 9. The spring 26 then opens the contacts and restores the armature 25 into holding engagement with the magnet 18. A hollow 27 or a peripheral groove, Fig. 2 (not shown) at the back of the armature 25 may communicate with atmosphere through a channel 28 so that air pressure acting on the armature assists the holding action of the magnet.

Title: Improvements in nuclear reactors
IPC: G02B1/10
Filed: 1972-08-07
Abstract: 1422796 Fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 30 July 1973 [7 Aug 1972] 36815/72 Heading G6C A nuclear reactor fuel element assembly comprises a cluster of spaced, parallel fuel pins 2, 3 within a tubular casing 1, the innermost fuel pins 3 which contain fissile material being located in an inner duct inside a baffle 9 and the outermost fuel pins 2 which contain breeder material being located in an outer duct between the baffle 9 and the casing 1, and gagging means for restricting coolant flow through the ducts on either side of the baffle 9 so that the temperature of the coolant in the outer duct is lower than that in the inner duct. The temperature of the casing 1 is thereby reduced, resulting in a lowering of the irradiation induced voidage growth which is temperature dependent. In the case of a fuel element assembly for a sodium-cooled fast reactor, the casing 1 and the sheaths of the fuel pins 2, 3 are of stainless steel. An extension sleeve 12 is fitted into the lower end of the casing 1 and houses a gag assembly 18. The gag assembly 18 comprises an outer sleeve 19 which is a close fit in the bore 15 of the sleeve 12, a collet sleeve 20 which fits inside the outer sleeve 19, and a series of toroidal rings 22 carrying wire mesh discs 23 and fitting in longitudinally spaced annular grooves 24 inside the collet sleeve 20. The lower end of the baffle 9 fits closely about a fuel pin support grid 5 which constitutes the upper end of the outer sleeve 19. Longitudinal slots 25 in the bore 15 connect between a conical throat 16 at the upper end of the bore 15 and ports 28 in a gag ring 26 fitted in the lower end of the bore 15. The gag ring 26 can be adjusted in angular position before charging of the. fuel element assembly into a reactor core so as to adjust the degree of overlap of the ports 28 with the slots 25, in order to preset the rate of coolant flow over the breeder pins 2 to the required amount. A spike member 29 at the lower end of the fuel element assembly comprises an upper adaptor sleeve 30 and a lower nose piece 45 by means of which the assembly is mounted in the upper and lower plate members 59, 60 of a diagrid 58. Coolant passes into the fuel element assembly from the interspace between the plate members 59, 60 via a filter assembly 49 surrounding the spike member 29. The filter assembly 49 comprises a wire gauze filter sleeve 57 surrounding a frame formed of upper and lower toroidal ring members 50, 51 joined by longitudinal rods 52 which are spaced by inner ring members 53. The main coolant flow is through the gag assembly 18 and then over the fissile pins 3. However, a proportion of the coolant passes through the ports 28 in the gag ring 26 and then through the longitudinal slots 25 in the bore 15 of the extension sleeve 12, before passing over the breeder pins 2 and the inner wall of the casing 1.

S., 34, Uvedale Road, both in Enfield, Middlesex. Dec. 30, 1932, No. 36876. [Class 135.] In a pressure cable or like installation employing two fluid pressure systems, one of which fluids is a liquid, and wherein the pressures of the two systems are balanced against each other by a pressure compensator of the bellows type, the bellows is protected against excessive expansion and contraction by a double valve which controls the flow of fluid to and from the bellows. Fig. 1 shows the terminal arrangement of a pressure cable installation in which the pipe pine a connects to a trifurcating box b having oil-filled pipes c<1>-c<3> through which the cores of the cable separately pass to end bells d<1>-d<3>. The pipe line and trifurcating box are placed under pressure by gas which is fed from gas-filled cylinders s through pipes j<2>-j to the trifurcating box. The gas pressure in the pipe line is balanced against the oil pressure in the cable by a compensator i comprising a casing k which communicates with the gas pipe j<2> and within which is disposed a bellows h. The bellows h contains oil and communicates with the oil-filled pipes c<1>-c<3> through a pipe g. To protect the bellows from excessive extension or contraction, such as would be produced by an abnormal temperature rise in the system or by a leakage of oil, a double valve l<1>, l<2>, Fig. 2, mounted on a spindle l attached to the bottom of the bellows, preferably by a flexible connection n, is fitted in the oil inlet of the bellows, the valve being adapted to close the oil inlet when the bellows expands or contracts beyond predetermined limits. A pointer l<4>, carried by the spindle and which moves over a scale on a sight glass r mounted in a dome q attached to the compensator, indicates the extension of the bellows. A differential pressure gauge p<3>, Fig. 1, gives an electrical warning when the pressures on the two sides of the bellows become unbalanced by a predetermined amount, say, one atmosphere. Pressure gauges p<1>, p2, connected respectively to the gas system and the oil system, give warning when the gas and oil pressures rise or fall to abnormal values. In a modified system the pressure rise or fall to abnormal values. In a modified system the pressure pipe line extends beyond the trifurcating box b to the end-bells.
