Abstract: 1410936 Polyvinyl acetal films COMPAGNIE GENERALE D'ELECTRICITE 18 Dec 1972 [16 Dec 1971 18 Feb 1972 4 Aug 1972 8 Aug 1972 10 Aug 1972 (2)] 58401/72 Heading B5B [Also in Division H1] An alkaline electrolyte storage cell, e.g. of the Zn, AgO or Cd, Ni type, includes a separator in the form of a diaphragm or membrane which divides the cell into two compartments and which is constituted by a partially reticulated polyvinyl acetal produced by combining polyvinyl alcohol with two different aldehydes. Alternatively the acetal may be produced by combining polyvinyl alcohol with an aldehyde and an organic diacid. The polyvinyl acetal is partially reticulated by an organic diacid, e.g. oxalic acid, wherein the ester functions produced comprise 0À1-10% of the number of acetal functions. An anti-oxidizing agent is preferably incorporated in the separator and may comprise an alkyl phenol, e.g. 4-anilo phenol, 4,4<SP>1</SP>- methylene - bis - 2,6 - ditert. - butyl phenol, an amine derivative, e.g. paraphenylene diamine, di-betanaphthyl paraphenylene diamine, or a quinone derivative, e.g. parabenzoquinone hydroquinone. The separator may be prepared by (a) dissolving polyvinyl alcohol in water to which is added at least one element supplying sufficient of at least one aldehyde to convert the alcohol to acetal, an organic diacid reticulating element and an anti-oxidizing element, (b) pouring the solution from (a) on to stainless steel plates and allowing to dry, (c) heating the diaphragm obtained in (b) in a non-oxidizing atmosphere at 120-250 C., preferably at 170- 185 C., for 1-3 hours, and (d) then impregnating the diaphragm with water. The acetalization is preferably effected by formaldehyde formed by the decomposition of dimethylol urea in the presence of an acid catalyst, e.g. ammonium chloride, sulphuric acid or phosphoric acid. The aldehyde used may alternatively be an aromatic aldehyde such as para-anisaldehyde, and the hydrophilic and electrical resistance properties of the separator may be improved by at least partially replacing the hydroxyl  radicals of the polyvinyl alcohol eliminated in the acetalization by hydroxyl radicals substituted on the nucleus of the aromatic aldehyde. This hydroxyl radical can be supplied by a phenol function, an acid function or a sulphonyl function. The acetal function may also be formed by utilizing conjointly formaldehyde and one of salicylic aldehyde, 4-carboxybenzaldehyde or orthobenzaldehyde sulphonic acid.

Patent GB-664363-A (GB)
Abstract: 664,363. p - (Halogenoacylamido) salicylic acids and salts thereof. WARD, BLENKINSOP & CO., Ltd., GOLDBERG, A. A., and THOMAS, N. L. July 1, 1949 [July 2, 1948], No. 17850/48. Class 2 (iii). A process for the production of a salt of a p - (halogenoacylamido) salicylic acid comprises treating a para-amino salicylic acid or a salt thereof with a halogenated aliphatic carboxylic acyl halide in the presence of an acid acceptor. Preferably an aqueous solution of a water-soluble salt, e.g. an alkali metal salt of the para-amino-salicylic acid is diluted with a water-miscible organic solvent such as acetone and the halogenated acyl halide is dissolved in the same solvent and added in small portions, the reaction mixture being maintained neutral or slightly alkaline by portionwise additions of alkali. Substantially stoichiometric amounts of the acyl halide and alkali may be added substantially simultaneously to the reaction mixture. Preferred alkali metal salts are those of sodium and potassium and the preferred alkalis are caustic alkalis such as sodium or potassium hydroxides. Alternatively the halogenated aliphatic acyl halide may be added to a solution of the para-aminosalicylic acid in an organic base such as pyridine or a picoline, treating with alkali and liberating the free acid by acidification preferably with a mineral acid such as dilute hydrochloric or sulphuric acids. The preferred acylating agent is an acyl chloride or bromide of a saturated halogenated aliphatic carboxylic acid which may be halo-substituted in any position, preferably in the #-position, e.g. chloracetyl chloride, bromacetyl bromide, α - bromo - propionyl bromide, #-chloropropionyl chloride, #-chloron-butyryl chloride or #-bromoundecyl chloride. In examples: (1) the N-chloroacetyl derivative of 4-aminosalicylic acid is obtained from 4- aminosalicylic acid dissolved in water with sodium hydroxide by adding chloracetylchloride in acetone simultaneously with sodium hydroxide and adding hydrochloric acid to precipitate the free acid; (2) 4-(chloropropionamido)-salicylic acid is prepared from sodium para-aminosalicylate by adding to the aqueous solution #-chloropropionyl chloride in acetone and sodium hydroxide and after removal of acetone precipitating the free acid by addition of dilute hydrochloric acid; (3) 4-(10<SP>1</SP>-bromodecane carboxylamido)-salicylic acid is similarly prepared using 10-bromodecane carboxylic acid chloride.

Title: Thermal print bar
IPC: B41J2/345
Filed: 1978-07-14
Abstract: A thermal printing bar, as for a facsimile printer, comprises a continuous bar 11 of electrically resistive material on a surface of an electrically insulating substrate 10 and a pattern of associated conductors 13 extending beneath the bar on each side thereof to produce two rows of hot spots in the printing bar. The hot spots in one row are offset relative to the other row. By suitably sizing the hot spots, the spots in one row will at least completely fill the gaps between the spots in the other row, or can even overlap. By this means, the one row is first printed on the paper; the paper moved by the distance between the centres of the rows and then the other row printed. This provides contiguous or overlapping spots on the paper, giving improved contrast. As shown, the hot spots extend between the end 14 of each conductor 13 and a common central conductor 20, as indicated by lines 17. <IMAGE>
