Abstract: 249,160. I. G. Farbenindustrie Akt.- Ges., (Assignees of Akt.-Ges. f³r Anilin- Fabrikation). March 14, 1925, [Convention date]. Triarylmethane dyes.-Violet dyestuffs of the triarymethane series are obtained by condensing a tetra-alkyl-4 : 4<1>-diaminobenzophenone with an arylated or both arylated and alkylated ethylenediamine having no substituent in the aryl residue in' p-position to the nitrogen. When the product is a basic dyestuff it can be converted into an acid wool dyestuff by sulphonation. In examples, tetramethyl-4: 4<1>-diaminobenzophenone is condensed with the following diamines, in presence of toluene, by means of phosphorus oxychloride dimethyldiphenylethylenediaminediethyldiphenylethylenediamine, dibenzyldiphenylethylenediamine, th e product being sulphonated, and di-o-tolylethylenediamine. The 3-tolyl, 3-chlorphenyl, and xylyl derivatives of ethylenediamine (obtainable by the reaction between one molecular proportion of symmetrical dichlor- or dibromethane and two molecular proportions of m-toluidine, m-chloraniline, or a xylidine, e.g. 4-amino-1: 3-dimethylbenzene) may also be used, and the tetramethyl-4-4<1>-diaminobenzophenone may be replaced by the tetraethyl compound.

Title: Improvements in and relating to the production of conjugated diolefines
Inventor: HABESHAW JOHN
IPC: C07C1/247
Filed: 1961-02-27
Abstract: In the production of conjugated diolefins by the decomposition of a 1,3-dioxane in the presence of steam, the reaction is effected in the presence of a catalyst carrier and boron phosphate is continuously transported to the carrier in a vapour stream.  In one embodiment steam with or without an inert gas is passed over a separate bed of boron phosphate at 350 DEG -450 DEG C., mixed with the dioxane and together passed over the carrier which may be silica gel, diatomaceous earth, alumina, silica-alumina or fullers earth. In a second embodiment the mixed dioxane-steam feed is passed over separate beds of boron phosphate and then the carrier which may be in separate or the same reactor or in a modification the boron phosphate and carrier are mixed.  Preferably the boron phosphate is heated to 300 DEG -1000 DEG C. before use and preferably steam is passed through the boron phosphate and the carrier before the process is begun.  The amount of boron phosphate transported may be 0,1-1 part per 1200 parts by weight of dioxane fed.  The process is otherwise effected as in Specification 873,875.  The conversion of 4,4-dimethyl-1,3-dioxane to isoprene is exemplified.

Title: Improvements in control systems for electric motors
IPC: B66C13/24
Filed: 1930-03-05
Abstract: 343,766. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London.-(Assignees of White, H. E. ; 1302, Singer Place, Wilkinsburg, Pennsylvania, U.S.A.) March 5, 1930, No. 7234. Convention date, March 6,1929. [Class 38 (iii).] Regenerative braking; field and armature control.-A motor armature 1 and its field 2 are connected in series for hoisting and in parallel for lowering, and asymmetric resistors or rectifiers are associated with the circuit so as to give repaid acceleration and strong regenerative braking during lowering even if the master controller is in the field-weakening position. A master drum controller causes closure of contractors 4, 5, 6, Fig. 2, to give the series connections, and in succeeding positions causes closure of contractors 23, 28, 32 to cut out the resistance 22. In the first lowering position contractors 4, 5, 23, 28, 32, 40, 41 are closed to give a shunt circuit with strong field, and in succeeding positions contractors 23, 28, 32 are opened to weaken the field, the motor circuit is now as shown in Fig. 3. Should the operator increase the resistance 22 before the motor has accelerated, part of the armature current is drawn by way of field 2 and rectifier 53 from the positive main, thereby giving a strong starting torque. If the load being lowered is heavy and the resistance 22 has been increased, part of the current regenerated by the armature flows by way of the field 2 and rectifier 57 to the positive main 7, thereby increasing the field and giving substantially the same lowering speed as for a light load.

Filed: 1978-02-28
Abstract: The centring plate (1) is mounted via the ball mounting (2) on the fastening bolt (3), in such a way that it can rotate freely in one direction. The freewheel (10) allows this one direction of rotation, whereas, in the other direction of rotation, it is blocked and thus prevents the reverse rotation of the centering plate (1) via the bolt (11) connected to the centering plate (1). The fastening of the centering plate (1), which, during operation, receives the hollow-cylindrical tube (6) for the winding of textile threads, on the ballbearing (2) takes place by means of a plurality of claws (7) which are distributed over the circumference and which snap positively over the outer race (8) of the ballbearing (2). In the region of the ballbearing (2), the bolt (3) is provided on the end face with a centric bore (9), in which a freewheel (10) is accommodated. A bolt (11), which engages into the freewheel (10), is provided at its end with a knurling (12) and, by means of this, is fitted positively into the centering plate (1). This centering plate can no longer rotate in an uncontrolled manner opposite to the winding direction, which hitherto has led to an uncontrolled unwinding of the textile threads. <IMAGE>
