Title: The manufacture of ortho-carboxyamido arylthioglycollic acids
Filed: 1928-06-19
Abstract: 319,075. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). June 19, 1928. o-Carboryamidoaryl-mercaptans and thioglycollic acids; o-carboxyarylthioglycollic acids.-A substituted o-cyanarylsulphochloride is treated, in the presence of an organic solvent, with a metal or a metal salt having a reducing action, together with a strong mineral or organic acid having a hydrolizing action, the reaction being regulated so that no nitrogen of the cyanic group is split off, and the resulting o-carboxyamidoarylmercaptan is condensed with chloracetic acid in alkaline solution to give o-carboxyamidoarylthioglycollic acids. According to examples, 1-methyl-2-cyano-5-chlorbenzene-3-sulphochloride, 1-methoxy- and 1-ethoxy-4-cyanobenzene-3-sulphochlorides and 1-chlor-4-cyanobenzene-3-sulphochloride are reduced and hydrolized, in the presence of benzene or chlorbenzene, by means of zinc dust and hydrochloric acid to the corresponding o-carboxyamidomercaptans which are then coupled with chloracetic acid to give 1-methyl-2- carboxyamido-5-chlorbenzene-, 1-methoxy- and 1- ethoxy-4-carboxyamidobenzene- and 1-chlor-4- carboxyamidobenzene-3-thioglycollic acids. In a further example, 1-methyl-2-cyano-5- and G- chlorbenzene-3-sulphochlorides are reduced and hydrolized by means of zinc dust and glacial acetic acid, in the presence of benzene or chlorbenzene, and the resulting o-carboxyamidomercaptans coupled with chloracetic acid. Finely powdered iron and stannous chloride are mentioned as reducing agents, and formic acid and the sulphonation products of naphthalene may be used for effecting hydrolysis. The removal of ammonia from the o-carboxyamidoarylthioglycollic acids by heating with dilute caustic soda to give the corresponding o-carboxyarylthioglycollic. acids is referred to. o-Cyanarylsulphochlorides are prepared from the corresponding o-aminoarylsulphonic acids by converting the amino group into the cyano group bv Sandmeyer's reaction, and treating with phosphorus pentachloride or an excess of chlorsulphonic acid. Thus, 1-methyl-5-chlor- and 1- methyl-6-chlor-2-aminobenzene-3-sulphonic acids, 1-methoxy- and l-ethoxv-4-aminobeuzene-3-sulphonic acids and 1-chlor-4-aminobenzene-3- sulphonic acid are converted first into the corresponding o-cyanoarylsulphonic acids and then into the o-cyanoarylsulphochlorides.

Filed: 1963-05-07
Abstract: 1,036,582. Knitting-machines. WERKMASCHINENBAU LIMBACH-OBERFROHNA VEB. May 7, 1963, No.18035/63. Headings D1C and D1K. A warp knitting machine comprises two beds of eyed needles 1, 2 which are inclined in the same direction with respect to the longitudinal axis of the respective needle bar and are so disposed in relation to one another that the free end 14 of an eyed needle of one row lies approximately opposite the apex 15 of the bend of a needle in the other row when the needles are advanced. Three methods of knitting are disclosed for this type of machine. In the first method (Fig. 3) the eyed needle 1a advances to take a loop 19 from needle 2a and the needle 2a is then retracted Fig. 5 (not shown) leaving its loop 10 on needle 1a, needle 2a is then again advanced and takes a loop 20 from an adjacent needle 1b Fig. 7 (not shown) due to the bending of the needles. A separate thread 24 Fig. 11 (not shown) is fed by means of a yarn feeder 23 which passes through the sinker looms of the stitch courses 25, 26 so that they are locked. The needles involved in this operation are le, 2e and 2ee Fig. 2 (not shown) and they form these courses 25, 26 into a selvedge longitudinal edge. In the second example the needle row 2 is reached by one needle space in the direction of the arrow and back to its original position during knitting and a fabric is produced (Fig 16) in which a stitch 19 formed by the one warp thread alternates both in the stitch courses and in the wales with a stitch 20 which consists of the other warp. In the third example of this method a double wale fabric is produced on two opposite needles as shown in Fig. 19 (not shown), one needle row is rached in such a manner that the needle 2a always takes the loop 20 from needle 1a and needle 1a always takes the loop 19 from needle 2a. A yarn guide 27 feeds a weft thread 28 to each pair of needle pairs 1a, 2a and 1b, 2b Fig. 24 (not shown) and the fabric shown in Fig. 25 is produced by this method.

[Classes 83 (i) and 83 (ii)] [See also Group XVI] Casting processes.-A method of producing or renewing a printing-cylinder, consisting of a metal roll or backing member and a layer of metal or alloy having properties suitable for a printing-surface, comprises uniting the base roll or backing member and the layer metal at the temperature of fusion of the base roll or backing member. The base-roll 9 is cleaned by abrasive or by pickling in hydrochloric or hydrofluoric acid, heated to its melting point, and dipped in a bath of molten copper, or fumed in the vapours of molten tin, zinc, or the like. A thin welded film 12 is thus formed on the surface of the base-roll. The roll may then be centred in a suitable mould and molten copper, brass, bronze, or zinc is poured in to form the layer 11, which extends across the ends of the base-roll at 14. The base-roll may be kept in a neutral atmosphere prior to, and during casting, or the casting may be performed in vacuo. The copper layer 11 may be electrolytically deposited on the welded film 12. Alternatively, the copper layer is preformed as a shell, the inner surface is coated with a protective paint containing aluminium, and the base-roll is cast within it. After an intaglio roll has been used and the surface has been ground off, a new surface may be applied by the method described, or may be electrically deposited on a film welded to the base-roll.
