[Also in Division C3] A process for producing a microporous sheet material comprises coating a substrate with a solution comprising a film-forming urethane polymer in a water-miscible organic solvent and coagulating the polymer by treating the coated substrate with an aqueous solution of at least one water-soluble organic or inorganic salt of lithium, sodium, potassium, calcium, aluminium, magnesium, copper, iron, zinc, manganese or ammonium. A number of suitable polyurethanes are specified. A chain extender may be used, such as hydrazine, ethylene diamine or methylene di(ortho-chloraniline). An accelerator, such as triethylamine, triethylene diamine, N-ethyl morpholine, dibutyl tin dilaurate or cobalt naphthenate may be present in the polyurethane elastomer. A small amount of other polymers may be present in the polyurethane solution, such as polyvinyl chloride, polyvinyl alcohol, polyacrylonitrile and polyacrylic acid esters and copolymers containing vinyl chloride, vinyl alcohol, acrylonitrile and acrylic acid ester units. The solvent for the polyurethane may be N, N-dimethyl formamide, dimethyl sulphoxide, tetrahydroflurane, tetramethyl urea, N, N-dimethyl acetamide, dioxane, butylcarbinol and mixtures of these. Ketones such as acetone and methyl ethyl ketone may be used as diluents. The substrate may be a fibrous mat such as a non-woven fabric or felt, woven or knitted fabrics and sheets, films or plates of synthetic resin, metal or glass. The concentration of salt in the aqueous solution may be from 10 grams/litre to saturation at 30‹C. Numerous suitable salts are specified. Coagulation may be effected at from 10 to 50‹C. Urea may be added to the polymer solution and the resulting film is improved with regard to a moisture permeability without adversely effecting the advantages obtained by the use of the aqueous salt coagulating bath.

Title: Method of and apparatus for shearing spent nuclear fuel bundles
IPC: G21C19/36
Filed: 1971-12-10
Abstract: 1314803 Shearing; consolidating scrap ALLIED CHEMICAL CORP 10 Dec 1971 [15 Dec 1970] 57527/71 Headings B3H and B3W [Also in Division G6] Apparatus for shearing spent nuclear fuel bundles into pieces of predetermined length for further processing comprises a sealable magazine for receiving a fuel bundle 17 (shown in cross-section in Fig. 3), means for urging the bundle forward, a horizontal gag 27 and a vertical gag 30, or alternatively two parallel-acting horizontal gags (67, 68) operated in conjunction with a vertical restraint (70) (Figs. 8 and 10, not shown), for compressing the front portion of the fuel bundle 17, and a shear blade 25 adjacent to the gags, whereby the fuel bundle may be urged forward in increments, compressed and sheared. When the gags 27, 30 are operated, the vertical gag 30 which is sufficiently wide to overhang the horizontal gag 27 compresses the end of the fuel bundle 17 downwardly until it contacts the gag 27, whereupon it remains fixed and restrains the bundle as the gag 27 slides beneath it to further compress the end of the bundle against a shear anvil 53. The contact face of each of the gags 27, 30 slopes gently toward the bundle to be compressed, with the portion of the face which projects further toward the bundle being nearer to the shear blade, in order to reduce the risk of breakage of the fuel rods in the bundle which are frequently rather brittle as a result of neutron irradiation. The edges of the gags should be rounded. The shear blade 25 is attached to a shear block 57 actuated by a remotely-controlled hydraulic cylinder 26 which lies outside a concrete barrier 22. The alternative arrangement employing two horizontal gags (67, 68) referred to above is advantageous in shearing off the fuel bundle end fittings for when one gag holds an end fitting, the other gag is free to compress the fuel rods adjacent to the fitting.

Abstract: 1452968 Data storage systems INTERNATIONAL BUSINESS MACHINES CORP 19 Dec 1973 [26 Dec 1972] 58902/73 Heading G4C An apparatus for recording data on a magnetic medium includes a modulo-R byte counter which divides a string of data bits into a number of full segments and a residual segment. Each full segment contains R bytes of the string and a number of check bytes relating to the R data bytes. The residual segment contains those data bytes which remain, if any, when the full segments have been formed. This segment also contains check bytes and padding bytes such that the number of data bytes and padding bytes in the residual segment is R. On detection of the last full segment an end of data segment is recorded prior to the residual segment. The segments may be recorded as parallel-bit bytes on multi-track magnetic tape. A preamble segment precedes the first segment. The residual segment which may be omitted if there are no residual bytes is followed by a check byte segment and a postamble segment. A second counter counts, modulo-K, the number of bytes in the string of data. If R is odd (e.g. 7) K is even (e.g. 32) and vice versa and consequently the sum of the R and K counts at the end of each segment is alternately odd and even. This characteristic may be used to verify correct formatting. The check segment includes a byte indicating the number of data bytes in the residual segment and the number indicated by the modulo K counter at the end of the string. Resynchronizing segments are inserted periodically. The tape may be read in either direction.
