Patent GB-540323-A (GB)
Abstract: 540,323. Calculating-apparatus. BALL, W., KEEN, G. P., and BRITISH ADDING & CALCULATING MACHINES, Ltd. April 29, 1939, No. 18175/40. Divided out of 540,283. [Class 106 (i)'] A machine having a number of totalizers, with the wheels arranged in denominational sets around actuating gears associated with the differential mechanism, is provided with a transfer mechanism comprising an operating member for each denomination, rotatable about the axis of the actuating gear and having a number of equally spaced abutments, at least one for each totalizer, to co-operate with a transfer tooth or abutment on a wheel of the selected totalizer whereby a step by step unidirectional movement is imparted to the operating member to operate an auxiliary transfer member to condition the next higher differential actuator to effect a transfer movement. The invention is shown applied to a machine as described in Specification 540,283 with totalizer selecting mechanism as described in Specification 540,314 and a grand total register as described in Specification 540,312. Transfer mechanism.-The wheels 11 of a denominational set for a number of totalizers are arranged circumferentially around an actuating gear 57 on spindles 54, Figs. 1, 2 and 3 rotatably mounted in a carrier plate 56. The plate 56 supports a transfer operating member or ring 91 provided with a number of equally spaced pegs 92. Each totalizer wheel carries a transfer abutment 90 that co-operates with a pin 95, Fig. 3, on one arm of a pair of co-operating levers 93, 94 pivoted on the carrier plate 56. At transfer an extension 99 on the lever 94 engages one of the pegs 92 and rotates the ring 91 step wise through the pitch of the pegs. This movement rocks a bell crank lever 106, 107 so as to withdraw a pin 105 thereon from the limb of an inverted T-slot in the rack 14 of the next higher denomination. This action frees the rack near the end of the outward or return movement of the actuating rack 12 to allow an additional step movement after freeing latch members 112 or 109. The rack 14 is restored at the end of the operation by a depression 237 in the corresponding operating cam 42. The bell crank 106 is held by a latch 108A in displaced position which is released at the beginning of the next operation. Transfer operations in the grand total register are conditioned by transfer abutments 110A engaging projections on the bell cranks 106. The totalizer wheels 11 are held in aligned position when out of engagement with the driving gears 57 by means of a ring plate 166 with wedge shaped projections 169 arranged to engage a facet on a polygonal disc 165 on the wheels. The ring plate 169 is operated by a lever 170. Specifications 263,505, 288, 672, [both in Class 106 (i)], 343,448, 343,473, 343,474, 343,475, 343,476, 352,958 also are referred to.

Filed: 1973-11-29
Abstract: 1448250 Reactors SIEMENS AG 29 Nov 1973 [30 Nov 1972] 55521/73 Heading G6C In the change-over of fuel elements from an outer zone of a reactor core to the central zone a first fuel element is withdrawn from the outer zone, tested to ascertain whether or not it is defective in a given sense and, in dependence upon whether or not it is found by the test to be defective, either not then replaced in the reactor core or replaced in the central zone, this operation being repeated for each of the fuel elements in turn. In each operation, a fuel element 51 is extracted from the reactor core and transported with the aid of a charging machine under water and through a lock into a decay tank 2 where it is set down in one of a pair of testing chambers 7. Since there are two such chambers 7, testing of the next fuel element 51 can be taking place during the transport time of the one element which has already been tested. Each testing chamber 7 is provided with a bell-shaped cover 71 removable by a remote-contral device (not shown). The testing chambers 7 are connected at their bases with the tank water so that when water from a chamber 7 is pumped off to a measuring device 10 a replenishing supply of fresh water is immediately introduced from the tank 2. Since during a heating-up period of approximately 20 minutes there must be no flow within the testing chambers 7, compressed air is introduced into the covers 71 via lines 72, 73 and valves 81, 82, 85 so that an air cushion is formed in the chambers 7 above the fuel elements 51. At the end of this period, a valve 94 in the pipe system 75, 91, 98 is opened and water is drawn out of a testing chamber 7 with the aid of a water-jet pump 96. The water is thus conveyed out of the chamber 7 and through a measuring container 9 which together with the measuring device 10, e.g. a gamma detector, is housed within a lead shield 11. A cryostat 100 also within the shield 11 serves to cool the device 10 with liquid nitrogen. Amplifiers and analysers at 12 enable the operating staff to read-off without delay whether or not the fuel element under test is in order. To prevent the deposition of radio-active corrosion products, the inner walls of the container 9 are polished smooth and a cleansing device 93, e.g. a rotatable brush, is provided.

Abstract: 1410346 Casting ceramic handles GOUGH & CO (HANLEY) Ltd 30 Nov 1973 [1 Dec 1972] 55601/72 Heading B5A Handles for ceramic hollow ware are cast in mould cavities 10 in which the mating lines 20 between the mould halves 1, 2 extend along the length of each cavity on either side of and as far distant as possible from its plane of symmetry. Two lines of cavities 10 are filled by pouring slip into channels 9, air being vented from the cavities through passages 21 and common vents 22. Moulds are placed end to end with their channels 9 in communication on a conveyer 4 (Figs. 3 and 4, not shown), their notches 23 engaging ribs (5) on the conveyer. Slip is metered from a reservoir (6) by a peristaltic pump (7) through nozzles (8) into the channels 9, and a tickle of slip is fed from further nozzles (12) to top up the moulds. The conveyer (4) is inclined to cause excess slip to run back towards the leading end. The filled moulds pass through a drying oven 13 and, after unloading at the other end, the mould halves 1 are inverted (see dotted lines, Fig. 1) and the moulds returned through the drying oven on another conveyer (18). The handles are passed between two endless rubbing belts running at different speeds so as to fettle the handles as they lie flat between the belts.

Abstract: 1375556 Comparing voltage levels SIEMENS A G 3 Dec 1971 [5 Dec 1970] 56359/71 Heading G1U To measure the difference between two voltage levels V 1 , V 2 , a composite signal U 15  is produced whose amplitude attains the levels V 1 , V 2  in turn, and this composite signal is passed to two channels 3', 4', in one of which it is shifted in level by an amount V 1 , and in the other by an amount V 2 , the difference between the outputs of the two channels being measured (11-13). Each channel comprises a series capacitor 3, 4, one electrode of which is connected to earth by an f.e.t. switch 5, 6 when the composite signal is at a level V 1  or V 2  as appropriate and is isolated from earth at other times. This takes place repetitively under the control of clock pulses (14), so that the signal U 16 , U 1  7  applied via an isolating amplifier 7, 8 to the respective input of the subtractor 11 is identical to the composite signal U 1  5  except that it is shifted by V 1  or V 2 . The composite signal is applied to the two channels via a logarithmic amplifier 2. The levels V 1 , V 2  may represent unknown and reference currents or voltages (arising e.g. in photometry), or they may represent transients. The reference may be zero. The apparatus may be adapted for use with more than two voltage levels either by including more than two channels and comparing all channels with one another in succession, or by selecting only two voltage levels at any one time.

A fuel battery has an electrode stack having channels for gaseous fuel, gaseous oxidant and electrolyte formed at least in part by holes in the electrode frames and connecting respectively fuel, oxidant and electrolyte spaces adjacent the electrodes in which there are barrier spaces between frame parts forming the fuel channel and adjacent frame parts forming oxidant spaces and between frame parts forming the oxidant channel and adjacent frame parts forming the fuel spaces, the barrier spaces containing a material which prevents leakage of oxidant and/or fuel into the barrier space or prevents oxidant and fuel which have leaked into the barrier space from reacting, and the barrier spaces being sealed from the respective channels and fuel and oxidant spaces. The material may be water, electrolyte, CO 2 , N 2  or a cured body of epoxy resin; the fluid materials may be passed through the battery to remove gases leaking into the barrier spaces. As shown in Fig. 2, which is a fragmentary cross-section through the fuel channel 13 of an H 2 -O 2  fuel cell, the fuel channel 13 communicates with the fuel spaces 33 adjacent the anodes 26 but is sealed from the electrolyte spaces 35 between the electrodes, and from the barrier spaces 35e which encircle the fuel channel 13, are connected to the electrolyte spaces 35 by the gaps 54 between the thermoplastic resin frames 27, 29 and are filled with electrolyte. Between the oxygen spaces 34, adjacent the cathodes 28, and the fuel channel 13 or the fuel spaces 33 there is thus a space 35e or 35 filled with electrolyte. Welds 50h surround the fuel channel, 51 surround the periphery of the cell and 52g surround the circular apertures 53g in the oxygen frames. The oxygen channel 15 is similarly constructed to be separated from the fuel spaces 33 by electrolyte spaces 35e (Fig. 3, not shown). In another embodiment (Fig. 6, not shown) coolant spaces 57 fed from channel 58 are disposed on either side of the middle pair of cells. In a third embodiment a stack of cells is fed with fuel, oxidant and electrolyte through external, integral conduits in which fuel conduits are isolated from oxidant spaces and vice versa by barrier spaces which are filled with a cured epoxy resin or through which N 2 , CO 2 , H 2 O or other inert fluid is passed.
