Title: Apparatus for unwinding wire from reels
IPC: B65H49/12
Filed: 1975-03-20
Abstract: 1495827 Unwinding wires THOMSONBRANDT 20 March 1975 [22 March 1974] 11781/75 Heading D1J The invention relates to apparatus for unwinding from reels 6, 7 Fig. 2 the apparatus having the exterior form of two adjacent hollow, partly cylindrical and partly frustoconical elements 2, 3 united along their conical surfaces, each of the cylindrical portions thereof being adapted to receive a reel 6, 7.  According to the invention the union between the frusto-conical elements 2, 3 is such that it can be temporarily opened up in a manner forming a path between the elements 2 and 3 such that when one reel 6 is emptied the tail end thereof connected at 9 to the leading end of reel 7 can move across from one element to the other. Fig. 9 shows how the apparatus can be made of elastic material such that a jack 45 or the like can be used to temporarily force the edges 40 and 41 away from the edges 42 and 43 to provide a path between the elements 34, 35. Fig. 8 shows the apparatus in its closed arrangement such that there is no longer a path between the two frustoconical elements. Each frusto-conical row provides a smooth continuous inner surface to limit ballooning of the wire being unwound. Figs. 6 and 7 (not shown) show an embodiment similar to Figs. 8 and 9 except that hinges are provided to enable the relevant parts of the conical member to be moved to open and closed settings. Figs. 4 and 5 (not shown) show an embodiment similar to Figs. 6 and 7 except that the hinges are absent and the relevant parts of the conical members. can be completely detached from each other to enable said path to be temporarily opened up.

Abstract: 251,996. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). May 6, 1925, [Convention date]. Samples furnished. Thioindigoid dyes.-A 3-methyl-4:5-dihalogenphenyl-1-thioglycollic acid, or such a thioglycollic acid as contains in the 2-position a further carboxy, CONH2, or CN group, is converted into the corresponding oxythionaphthene by the usual methods and the latter oxidized to the thioindigo; or, the oxythionaphthene may be condensed with the usual indigoid dye components such as isatin, or dibromisatin chloride oranilide; further, the oxythionaphthene may be converted into a 3-derivative oi 4-methyl-5 : 6-dihalogen-2 : 3-diketodihydrothionaphthene and the latter condensed with appropriate components. The condensation of the 4-methyl-5 : 6- dichlor-3-oxythionaphthene with 6-ethoxy-2 : 3- dihydro-3-keto-2-(p-dimethylamino)-anil is excluded. According to examples (1) 3-methyl- 4 : 5-dichlor- or 3-methyl-4-brom-5-chlor-phenylthioglycol-2-carboxylic nitrile is heated with caustic soda and sodium sulphide, the resulting 3 - amino - oxythionaphthene - 2 - carboxylic acid warmed with hydrochloric acid to obtain the 3- oxy-1-thionaphthene, and the latter oxidized to the corresponding 4 : 4<1>-dimethyl-5 : 6 : 5<1> : 6<1>- tetrahalogenthioindigo by blowing in air in presence of copper hydroxide; (2) 3-methyl-4 : 5-dichlorphenylthioglycollic acid is converted into the thioindigo by means of chlorsulphonic acid; (3) 4-methyl-5 : 6-dichlor-oxythionaphthene is condensed with p-nitrosodimethylaniline and the resulting anil condensed with 7-brom-5 : 6-benzo- 3-oxy-1-thionaphthene. The products dye cotton from the vat in bluish-red, violet, &c., shades fast to light and kier-boiling. Thioglycollic acids. - 3-Methyl-4 : 5 dischlorphenyl-1-thioglycollic acid is obtained by subjecting 6-chlor-2-toluidine to the reactions described in Specifications 17417/14 and 18292/14 and removing the amino group from the 2-amino- 3-methyl-4 : 5-dichlorphenylthioglycollic acid so obtained. 2-Cyano-3-methyl-4 : 5-dihalogenphenyl-1-thioglycollic acid is prepared from the 2- amino compound in the usual manner; it yields the corresponding acid amide by hydrolysis with sulphuric acid. 3-Methyl-4 : 5-dihalogen-1-thioglycollic-2-carboxylic acid may be made from 6- halogen-2-toluidine by acetylation, halogenation, nitration, and removal of the acetyl group to obtain 5 : 6-dihalogen-3-nitro-2-amino-1-methylbenzene; the latter is then converted into the 2- carboxylic acid by way of the 2-cyano compound, and the nitro group replaced by S. CH2.COOH after reduction to the amino group.
