Abstract: 1,039,920. Workman's timekeeping; sorting digital data. SIEMENS & HALSKE A.G. Sept. 5, 1964, No. 36477/64. Headings G4M and G4T. In a workman's time keeping device, inserted tokens 2 (Fig. 4, not shown) are scanned at 1 and the data thereon stored, in a buffer store 3 and then in a predetermined order in a main store 6 determined by a selector 5 such that the data may be read out through selectors 8 to one or more recording devices 9 in said predetermined order. Preferably the order corresponds to a personel wages sheet. The buffer store 3 comprises relays or magnetic cores and the scanning is checked by comparison of two rows of identical punched digits on the token and by checking the sum of the digits, also punched. Any errors are counted and indicated. The time of receiving the data may also be stored by simultaneous reception of data from a timer 10 to operate an electromagnetic stepping switch (Fig. 3, not shown). The information may be stored in order of reception on a magnetic tape store 33. The address of the data, being a function of the data itself, is selected at 5 and the data transferred to the store 6, which comprises relays or a magnetic core matrix, for subsequent read-out through a selector 8 to the punched card or tape recorders 9. Two groups of scanners may be provided, one for checking-in and one for checking-out, whereby the stored data is cancelled. Additional data may be added to the store 6 by a control unit 63.

Title: Nuclear reactor fuel
IPC: C01G43/025
Filed: 1963-09-17
Abstract: A previously shaped, sintered and densified mass of hyperstoichiometric dioxide which may be uranium, plutonium, or thorium dioxide or mixtures thereof is treated to produce a hypostoichiometric product which has an improved thermal conductivity compared to the starting material by heating the dioxide material at a temperature above 1500 DEG  C. under at least one of the following conditions:-(a) in an oxygen-free gaseous medium maintained substantially oxygen-free throughout the heat treatment; (b) in vacuo; and (c) in the presence of a solid getter (which is not dispersed within said mass). The preferred temperature range is 1500 DEG  to 1900 DEG  C. and suitable getter materials are exemplified as graphite, Ta, Mo, W, and mixtures thereof.  The product, which may, for example, be represented by the formula UO2- x, where x is above zero up and to 0.3, may be used as a fuel element in a nuclear reactor when the element is either constructed of the previously prepared hypostoichiometric oxide, or the hyperstoichiometric oxide is used and the reactor operated so that the necessary above-mentioned deoxygenating conditions obtain. The fuel element may be assembled with a getter material as the core or the end caps of the element and the reactor operated so that the hypostoichiometric nature of the fuel is maintained. A hypostoichiometric oxide as prepared above, for example one having the formula UO1.97- 1.998, may be used as the active element in a thermoelectric device.

Abstract: 1,063,009. Continuous-casting machines. SCHLOEMANN A.G., and CONCAST A.G. Aug. 27, 1965 [Aug. 29, 1964], No. 37053/65. Heading B3F. In a continuous-casting plant in which a starter bar (4, 5), Fig. 2 (not shown), initially closes a mould (3), Fig. 1 (not shown), e.g. an arcuate water-cooled mould, the step (9) formed by the beginning of the casting at the joint with the head (5) of the starter bar (4) is reduced to facilitate passage through extractor rolls (7). The step (9) may be reduced manually or automatically by a flame moved with the casting or by blades or by compressing-rolls (25) the top one of which is screwed down when the step is encountered. To produce a step (9) which does not extend across the casting at right-angles to the direction of movement, the end face of the starter bar head (5) may consist of two inclined planes (21), Fig. 3 (not shown) or one such plane (22), Fig. 4 (not shown). These planes may be arcuate. In such cases the introduction to the extractor rolls (7) is gradual and thus these rolls themselves may reduce the step without ancillary apparatus.

The metal salt may be of calcium, zinc, cadmium, magnesium, lead, manganese, iron, cobalt, nickel or copper, and a saturated or unsaturated fatty acid containing 10-22 carbon atoms. The adhesive may be applied in the form of a solution in alcohol or as a dispersion by roll coating or spraying. The paper may comprise fibres of mitsumate, paper mulberry, manila hemp, rayon, polyvinyl alcohol or acrylic fibres. The thermoplastic film which may have a thickness of 5-10 Á may be made from polystyrene, polypropylene, polyethylene or vinylidene chloride-vinyl chloride copolymer.

Filed: 1970-07-31
Abstract: 1298257 Matrix displays RCA CORPORATION 31 July 1970 [25 Aug 1969] 37159/70 Heading G5C A display device comprises a cell containing transparent nematic liquid crystals 17 between transparent plates 11, 12, transparent electrodes 15, 16 associated with each plate and a plurality of planar elements 46 disposed over and inclined to one of the plates to prevent direct light passing. Parallel tin oxide strip electrodes on each plate are arranged to form a crossed array. Spacers are disposed between and bonded to the plates 11, 12. The elements 46 comprise opaque dull black vanes embedded in a transparent plastics material 44. Applying A.C., D.C. or pulsed D.C. potential between a pair of opposed electrodes causes local turbulence in the liquid, e.g. anislidene-p-aminophenylacetate which produces a forward light scattering state and a white appearance compared to the black background of the vanes visible through unenergized areas of the liquid. The degree of scattering is directly proportional to the potential above a threshold value. The electrodes may be sequentially energized or a number simultaneously energized to produce a fixed display.

[Class 60] [Also in Group XXXIV] In a machine for grinding small bores the tool Y is fitted to a spindle V clamped at 10 to the hub 61 of a turbine wheel O mounted in bearings N, N<SP>1</SP> in a block I. The latter is slidable in a casing H and its position can be adjusted by a nut 12 on a screwed shaft D acted upon by a spring C. The spindle V passes through an eccentric bore in the sleeve W and is supported by an inner bearing U and a conical outer bearing X. Air under pressure is supplied through a nipple G. A part thereof passes through a duct 16 conduits 5 and nozzles 7 to drive the turbine wheel O and is exhausted at 9 to the outside. Another part of the air passes through a felt pad F dipping into a lubricant sump 13 and passes through a small bore 19 to expand in a chamber 20 so as to cool and deposit excess lubricant. From the chamber 20 some of the air passes through the bearings N, N<SP>1</SP> to the exhaust port 9.

Class 95 [Also in Group VIII] Individual carton blanks having a smooth glossy coating of a thermoplastic agent are produced by applying a coating of the molten agent to one side of each of a series of blanks 10, 13, 14, 30 to 32, 36 to 38 (Fig. 1), e.g. by rollers 16, 18, 20 rotating in a bath of the agent; moving the coated surfaces of the blanks into intimate contact with a smooth, mirror-finished casting surface, e.g. a cold casting roll 23 against which the blanks are urged, e.g. by an impression roll 24, to become immovably disposed, moving the casting surface to carry the blanks towards and through a cold liquid bath, e.g. a waterbath 27, in which they are submerged for a sufficient time to ensure solidification of the coating, the blanks then being peeled from the casting surface. Cold water from a spout 26 may be applied to the uncoated side of the blank, splashing of the impression roll being prevented by a baffle 29. In the embodiment shown in Fig. I, the blanks, after emerging -from the water bath, are pressed between the casting roll and a rubber wringer roll, peeled from the casting roll by a knife 34, and removed by a conveyer 35. The knife 34 may be supplemented or even replaced by a nozzle directing a jet of air between the blanks and the casting roll 23. The knife may be located below the level of the water in the bath, and a pair of conveyer belts, also partially beneath such level, used to collect the coated blanks. The blanks may consist of paper of various types, plastic films, metal foil, paperboard and the like and the thermoplastic agent may consist of paraffin wax, microcrystalline wax, or polyethylene or polypropylene of low molecular weight, or mixture of these substances. The cold casting roll 23 may be surfaced with a sheet of polyvinyl acetate or of copper or aluminium foil, or with a lacquer of silicone or other resin, or it may be of polished metal, or be chromium- or nickel-plated. It may be replaced by an endless belt having a mirrorfinished surface.
