A press for moulding concrete panels includes a mould bottom comprised by a number of boxsection structures of the same length releasably secured together in side-by-side relation whereby the lengthwise dimension of the mould bottom can be altered; in order to provide a relatively small alteration in the length of the mould bottom one or more packing members are inserted between at least one pair of adjacent structures, and to provide a relatively small adjustment in width one or more members are releasably attached to an end of each structure. In Fig. 1 a plate 60 with shims 63, 64 is sandwiched between mould bottom structures 55 to increase the length of the mould bottom. The plate 60 has projections 61, 62 spaced along its length to engage apertures and recesses respectively in side plates 52 of adjacent structures. Alternatively the packing means may comprise a number of abutting units extending across the width of the mould. An alteration in mould width may be provided by a beam 66, Fig. 2, secured by bolts 67 between a side beam 20 of the mould bottom and a side-plate 56; the beam may be composed of a number of abutting short beams.

Abstract: 982,206. Thermionic cathodes. VARIAN ASSOCIATES. Nov. 1, 1962 [Nov. 29, 1961], No. 41420/62. Heading H1D. [Also in Division H5] A cathode heater comprises two wire strands 32, 33, Fig. 4a, wound to form a bifilar helical coil, which coil is then formed into a larger coil. Current is passed in opposite directions in the two strands so that magnetic fields set up by the currents in the two strands substantially neutralize one another. As shown, the two strands of the bifilar helix are connected in series by a turn 34 arranged in a plane perpendicular to the cathode surface 36. Alternatively, the two strands may be connected in parallel, the two ends 42, 43, Fig. 13, being passed down the centre of the larger helix 41. Instead of being formed into a larger helix, the bifilar helical coil may be wound into a flat coil, e.g. a single or double spiral or a zig-zag pancake coil. The cathode may be used in klystrons, travelling-wave tubes or magnetrons.

Abstract: 1483206 Automatic position control Mc NEIL CORP 26 Sept 1974 [3 Oct 1973]  41942/74 Heading G3N [Also in Division B3] For the movement of a machine element { endless band or knife cutting apparatus) intermittently, through a distance corresponding to the content of counter 39, the counter content being changed in correspondence with element movement until the content is equal to the set number, whence motor and brake 14 controls braking to a stop, the content is reset to zero at initiation of braking, and changes during overtravel of the member, the content reached when the member stops being retained in the counter. In a subsequent movement, the counter content changes, from the retained value as initial value for the movement, so that the total amount of movement, including overtravel, substantially corresponds to the set number. Initially the member is moved without working taking place, to set a first overtravel value in the counter. In subsequent movement, any change in the degree of overtravel will automatically be catered for by changes in the retained value. The motor and brake 14, via gearbox 11, drives screw shaft 13 translating the element 15, notches, on both sides of an indicator disc 24 rotating with the screw shaft 13, being sensed by LED/phototransistor sensor 26 during shaft rotation to alter the content of the counter 39. A manual control switch 40 is provided. The disc and sensor are sealed against dust entry by box 33, 34, 35, seal 36, and bellows seal 38.

Filed: 1957-04-23
Abstract: In the concentration of an isotope by exchange between chemically different, physically separable, first and second fluid substances by countercurrent contact in first and second exchange units at different temperatures, the impoverished first fluid leaving the second exchange unit is stripped to remove a content of second fluid, which is returned to the second contact unit.  The specific description is substantially identical with that of Specification 865,705 describing a cascade for production of heavy water by exchange between H2S gas and H2O wherein the water leaving the first hot column is stripped with steam to remove H2S which is returned to the hot column.  It is also stated that the process is applicable to exchange of Li6 and Li7 between an ethyl alcohol solution of LiCl and Li in mercury amalgam.  Specification 845,501 also is referred to.

Abstract: 1401316 Mechanical switches BUNKER RAMO CORP 19 Sept 1972 [1 Nov 1971] 43381/72 Heading H1N In a push button switch 10, Fig. 3, adapted for removably mounting on a printed circuit board 12, the plunger 30 which is non-rotatably slidable in guideways 24 carries at least three electrically connected contact elements 52, 54, Fig. 6, engageable with different fixed contact points 68, 70 on the board. The switch is particularly adapted for coding purposes, the two elements 52 first engaging predetermined row and column contacts 68 connected to a character coder (80), Fig. 7 (not shown), while the element 54 is recessed so that it engages a common contact 70 only after the other contacts have closed, thereby avoiding spurious signals. The movement of the plunger 30 between closure of the contacts 52 and 54 results in a sliding and cleaning movement of the contacts 52 on the fixed contacts 68. The switch housing 14 is mounted on the board 12 by a pair of integral posts 60A (60B), Fig. 2 (not shown), inserted through apertures 64A (64B) in the board and carrying spring clips 62 angled as at 66 to hold the housing 14 in position while permitting the housing to be forcibly removed. Projections 72, 74 on the board 12 are the same height as the printed circuit strips 68, 70 for engagement by the housing 14 to prevent rocking on the board 12.

Cushioning near the end of the working stroke of a hydraulic ram (26) supplied by a pump (12) delivering through a line (3) and a spool valve (2) when opened against a biasing spring by low pressure fluid admitted through a line (6) to one end of the spool (9) is effected by abutment of the ram rod (24) against the rod (25) of a spring- biased piston (22) within a buffer cylinder (20) and the resulting increase in cylinder space (21) serves to relieve pressure at the said end of the spool (9) to which space (21) is connected by a line (27) thereby allowing the spool valve to be returned by its spring to the closed position. The other end of low pressure line (6) is connected to one end of a master cylinder (8) having a doubleskirted piston (14) which when displaced to the right against a spring pressurizes fluid in line (6). The lower end of valve spool (9) is relieved through a line (7), a port (15) in, the other skirt of piston (14) a cylinder port (18) and a line (11) connected to a sump (13).

Title: Improvements in Conductive Liquid Metal Transfer Means for Plural Current Collectors
IPC: H02K31/04
Filed: 1967-09-28
Abstract: 1,190,036. Current collectors for dynamoelectric machines. GENERAL ELECTRIC CO. 28 Sept., 1967 [30 Sept., 1966], No. 44218/67. Heading H2A. [Also in Division F1] In a liquid-metal current collection arrangement, .e.g. for a disc-type homopolar machine as described in Specification 1,190,035, the migration of the liquid from one collector to the other is readjusted by moving liquid from one reservoir to another when their levels become excessively different. In the system shown, liquid migrates from collector 18 to collector 16, thus depleting reservoir 22 and over-filling reservoir 20. This imbalance is corrected when necessary by draining liquid into a sump 36 and pumping it up into the depleted reservoir 22 by means of the pressure of nitrogen 68. Circulating current is prevented by insulating pipeconnectors 48, 56, and by arranging that simultaneous exchange with both reservoirs and the sump cannot take place. The reservoirs have gas heads 30, 34 to balance the centrifugal pressure of the collectors. Selective communication of the reservoirs with the sump is allowed by electromagnetically operated valves 40, 54, the pressure head in the sump being appropriately vented to atmosphere through a regulator 74 or applied from a bottle 82. This pressure control is provided by electromagnetically operated valve 70 and ensures that alternative but not simultaneous connection to the reservoirs takes place. The liquid levels in the reservoirs are sensed by electrodes (150, 152 and 160) connected to a control circuit, Fig. 2 (not shown), energized by low-voltage A.C.
