Title: Manufacture of acid triphenylmethane dyestuffs
IPC: C09B11/26
Filed: 1935-02-08
Abstract: Triarylmethane dyes.--Acid dyes of the triphenylmethane series are obtained by condensing an indole substituted in 1- and 2-positions and substituted in 3-position by a p-chloro- or p-alkoxy-benzoyl radicle with a secondary or tertiary aromatic amine, including such amines of the heterocyclic series, thereafter causing the p-chlorine atom or the p-alkoxy group to react with a primary p-alkoxy-substituted aromatic amine and sulphonating the product. Alternatively, the sulphonation may precede the reaction with the primary amine.  The following examples are specified: (1) 1-Methyl-2-phenyl-3-p-chlorobenzoyl-indole (1 mol.) is melted at 100--105 DEG  C. with ethylbenzyl-m-toluidine (1 mol.), in presence of phosphorus oxychloride, and the condensation product is sulphonated and melted with p-phenetidine at 120--125 DEG  C.; the product dyes wool and silk clear reddish blue shades, very fast to light; (2) The ethylbenzyl-m-toluidine in (1) is replaced by ethylbenzylaniline to obtain somewhat redder dyeings; (3) 1-Methyl-2-phenyl-3-p-methoxybenzoyl-indole (1 mol.) is condensed with benzyl-o-toluidine (1 mol.) in presence of phosphorus oxychloride and the product is melted with p-phenetidine and thereafter sulphonated; the product dyes wool and silk clear violet shades, very fast to light; (4) 1 : 2-Dimethyl-3-p-chlorobenzoyl-indole (1 mol.) is condensed with dimethylaniline (1 mol.) and the product is melted with p-phenetidine and thereafter sulphonated; the product dyes wool and silk clear very reddish blue shades, very fast to light; (5) The dimethylaniline in (4) is replaced by benzyl-o-toluidine and the p-phenetidine by p-anisidine to obtain clear violet dyeings; (6) 1-Methyl-2-phenyl-3-p-chlorobenzoylindole (1 mol.) is boiled in benzene under reflux with N-ethylcarbazole (1 mol.) in presence of phosphorus oxychloride and the product is melted with p-phenetidine and thereafter sulphonated; the product dyes wool and silk reddish blue shades very fast to light; (7) The N-ethylcarbazole in (6) is replaced by 1-methyl-2-phenylindole to obtain a similar blue dyestuff.  Indoles, substituted in 1- and 2-positions and substituted in 3-position by a p-chloro- or p-alkoxyl-benzoyl radicle, are obtained by reacting the corresponding 1- and 2-substituted indoles with an arylide of a p-chloro- or p-alkoxybenzoic acid in presence of phosphorus oxychloride and treating the reacting mixture with a dilute acid.

Patent GB-1029972-A (GB)
Title: Method of bending glass sheets
IPC: C03B23/025
Filed: 1965-02-02
Abstract: A method of bending a glass sheet comprises heating the sheet to deformation temperature in an enclosed atmosphere, removing the sheet from the enclosed atmosphere and additionally heating the sheet while still at an elevated temperature before engaging the sheet in pressurized contact between complementary shaping members.  The additional heating means is preferably hot gaseous products.  A thin glass sheet (i.e. 1/4 -inch or less) supported vertically from its upper edge and at its deformation temperature, is conveyed from a heating furnace 12 (Fig. 1, not shown) into a relatively cold atmosphere.  The sheet is then passed above a gas burner 50, extending along the path of travel of the sheet and having in its upper surface a series of orifices 52, situated between complementary convex-concave bending members 30, 36 (Fig. 2, not shown).  A limit-switch contacted by the conveyer carriage causes the burner to light before the glass sheet passes over it and whilst the bending-members are retracted. A further limit switch activated by member 30 causes the burner to be extinguished before the bending members come into pressing engagement with the glass sheet.  In an alternative embodiment the sheet is exposed to the gas flames from the burner before it is passed to the bending station.  The faces of the bending members 30, 36 are covered with a layer of fibreglass or asbestos.  The invention is particularly suited to the bending of glass sheets for use as the face plates of cathode ray tubes.

Filed: 1966-02-02
Abstract: 1,086,188. Drilling and milling machines. CROSS CO. Feb. 2, 1966 [March 9, 1965], No. 4636/66. Headings B3B, B3C and B3K. [Also in Division F2] In a machine tool for drilling, milling etc. which includes a reciprocable tool carriage 17 having a rotary tool spindle 19 the carriage is slidably mounted by two tubular members 27 on guide rods 29 and two drive motors 21, 23 are provided to give respectively slow feed motion and rapid traverse to the carriage 17, the tool spindle 19 also being driven from the first drive motor 21. Limit switches 177, 179, 181 determine the extent of rapid traversal and tool feed motion, initiate return of the carriage and finally stop it in its retracted position. A stationary housing 22 encloses transmission gearing and is provided with an end cover on which the second motor 23 is mounted. The transmission gearing provides a high reduction for drive from the first motor 21 and low reduction for drive from the second motor 23 which is reversible; it includes two rotary annular gear cages 97, 99 and a ring gear 107 in mesh therewith internally and mounted on an eccentric 109. For rapid traverse in either direction drive is taken from the reversible motor 23 through gear 131 to a gear 123 integral with the cage 97 and therefrom through ring gear 107 to the cage 99 which is integral with an output shaft (57, Fig. 3, not shown) in splined connection with a screw member (39) which moves the carriage 17. For slow feed of the tool and carriage belt drive from motor 21 to a shaft (77, Fig. 3, not shown) and through gears 75, 73 causes the eccentric 109 to rotate and thus the ring gear 107 moves in an orbital path in mesh with cage 97 which is held stationary by means of a brake mechanism 137 attached to motor 23. Gear 107 causes the cage 99, which has slightly fewer teeth than cage 97 to rotate slowly and thus also shaft (39) rotates slowly to effect slow feed of the carriage 17. Tool spindle 19 is driven by the shaft (77, Fig. 3, not shown) which has a splined connection therewith. Housing 22 includes provision for mounting a further shaft above shaft (77) if further reduction gearing is required in the drive from motor 21. Reference is made to two proprietary gear units which may be substituted for the unit 25 described.
