Naphthalene dyes.-Naphthostyril or a substitution product thereof is condensed with a tertiary aromatic amine or with a phenol by means of an acid condensing agent. Acid wool dyes are obtained by sulphonating the products which are themselves dyestuffs. In examples, naphthostyril is condensed by means of piiosphorus oxychloride with dimethyl-, diethyl-, methylbenzyl-, methylcyclohexyl, ethylbenzyl- and dibenzyl-aniline, N-ethylcarbazole, N-methyldiphenylamine, dialkyl-alpha-naphthylamine, dialkyl- #-naphthylamine, m-diethylaminophenetol, mchlordimethylaniline m-chlordiethylaniline, pyrogallol, tetramethyl -0-phenylenediamine, tetramethylm-phenylenediamine and with N : N'- dimethyl-1 : 2 : 3: 4-tetrahydroquinoxaline. Diluents such as toluene and chlorbenzene may be used. When tertiary aromatic amines are condensed with naphthostyril, colour bases are first produced which are precipitated in acid solution as salts by means of sodium acetate, zinc chloride &c. The products comprise dyeatuffs which dye cotton mordanted with tannin, wool, silk and paper, bluish red, blue and blue-black tints. According to further examples, the condensation products from naphthostyril and dimethylaniline and from naphthostyril and pyrogallol are sulphonated bv means of oleum. Products are obtained which dye wool violet and yellow shades respectively, the latter changing to red-orange when after-chromed. Oxyhydroquinone, gallic acid and resorcinol are also mentioned as suitable phenols. and thionvl chloride as a suitable condensing agent which may be used in the process. Methylcyclohexylaniline is obtained by heating- cyclohexylaniline with a methylating agent such as dimethylsulphate and toluene-sulphonic acid methyl ester. N : N<1>-Dimethyl-1 : 2 : 3 : 4-tetrahydroquinoxaline is obtained by heating a hydrohalogen acid salt of 1 : 2 : 3 : 4-tetrahydroquinoxaline with methyl alcohol under pressure and decomposing the quaternary compound so produced by treatment with ammonia under pressure.

Abstract: 577,772. Cables &c. BEAVER, C. J., DAVEY, E. L., and GLOVER & CO., Ltd., W. T. Nov. 24, 1944, No. 23481. [Class 36] In a high-pressure gas-filled cable, the core, comprising stranded conductors 1, Fig. 1, pre-impregnated paper tapes 2, a conductive screen 3 and copper woven fabric 4 incorporating fine copper wire warps 4a, is enclosed in an envelope 5, folded round to fit the core and leave two flanges 6, which are soldered together. Over this is a layer 8 of copper woven fabric tape, metal tape 9, such as hard brass, steel, phosphor bronze, or cadmium copper tape, applied helically with a short lay, and a protective sheath 10. The envelope is applied by passing the core over a roll above which is a reel carrying a coil of metal tape, such as copper or brass tape. The tape 15 is drawn off the coil and passed under a cylindrical roller with a U- shaped groove so that it lies over the cable core 11 as shown in Fig. 5. The core and tape then pass through another set of rolls, one roll holding the tape 15 in contact with the top of the cable core 11 and side rolls bending the sides into engagement with the lower half of the core, leaving flanges 6 as shown in Fig. 6. The flanges, whose inner surfaces are tinned before the tape is applied to the core, are passed through a bath containing a non-corrosive flux, such as a mixture of colophony and resin oil, and then through a bath of molten solder, whose melting point is above 200‹C., such as one consisting of 56 per cent. tin and 44 per cent. lead. On leaving the solder bath, the core and tape are passed through three more sets of rolls, one pressing the flanges together, the second bending them through 45 degrees, and the third pressing them so that they lie alongside the surface of the envelope. Specification 393,694 is referred to.

[Class 35.] Motors with vapour or like rectifiers in place of commutators.-The commutator of a motor for driving a ship's propeller is replaced by an electric discharge apparatus and the speed of the motor regulated by means of the grid control of the discharge apparatus or byregulating the generator voltage. The Figure shows an arrangement in which the terminals of the generator winding 2 are connected to the star points of two polyphase windings of the propeller motor 6. The terminals of the motor windings are connected to the anodes of a rectifier 5 and the cathode is connected to the neutral point of the winding 2 through the rotor of the motor. The grids of the discharge device are supplied through a distributer 4 driven by the motor directly or through gearing. The speed of the motor is regulated by adjusting the voltage of the generator by means of a field regulator 7 and its direction by means of the distributer 4. In a modification the speed is regulated by changing the duration of contact of the voltage impressed on the control grids, the motor voltages being kept constant. In another modification a separate discharge apparatus is provided for each phase. The motors may operate with a series or compound characteristic or with separate excitation.

Title: Device using a shearing element in a fixed position to cut constant lengths from a strip moving past at high speed
IPC: B21B37/70
Filed: 1964-06-10
Abstract: 1,022,157. Shearing. SOC. NOUVELLE SPIDEM and COMPAGNIE GENERALE D'ELECTRONIQUE INDUSTRIELLE LEPAUTE. June 10, 1964 [June 12, 1963], No. 24036/64. Heading B3W. An apparatus for dividing strip one portion of which is driven at a constant speed by means 2, has gripping rollers preceding a shear 4, which is followed by a constant-speed conveyer 6 and is characterized in that the gripping rollers 3 rotate at a varying speed which is always lower than the speed of the conveyer 6 and are progressively decelerated prior to the cutting period to a small constant speed, stopped at the instant of cutting and immediately afterwards returned to their original speed prior to the progressive deceleration. Construction.-Strip from a coil 1 passes through a straightener 2 to feed rolls 3, 3a, through a reciprocating shear 4 to conveyers 6, 6a, 6b for removing the cut pieces of strip. A carriage 55 supports devices 7, 8, 8a, 9, 10 and 10a which detect the approach of the leading end of the strip. In the embodiment described photo-electric cells are used, other means referred to include limit switches, proximity induction devices and low-tension contacts directly bridged by the strip. The carriage 55 is movable to vary the length cut. The feed rolls 3, 3a are connected by gears 16, 16a and are driven through reduction gearing 17 by a D.C. motor 13 fed from a Ward-Leonard set. The motor drives a phonic wheel 18, Fig. 3 (not shown), which feeds signals through a gate 19, which opens when the leading end of the strip reaches the first detector, to a reverse counter 20. At the output from the counter is a converter for transforming the numerical values given by the wheel 18 into voltage signals of a corresponding amplitude. The converter is supplied by a tachometric generator 12a driven by the motor 12. The output from the converter is added to a small regulating voltage adjusted by a potentiometer 22 and constitutes a reference voltage for controlling the speed of the motor 13. When the leading end of a strip to be divided reaches the detector 7 the speed of the rollers 3 or 3a is progressively reduced until, when the leading end is a short distance from the detector 9, the speed is very low and is determined only by the potentiometer setting. When the detector 9 is reached the rollers 3, 3a are stopped and the shear operates.

Stuffing-boxes, substitutes for; packing, non- metallic.-Carbon packing segments engaging a turbine &c. shaft, or circumferentially grooved segments arranged with clearance around a, shaft, are so arranged that circumferential movement of the segments caused by excessive friction moves the segments radially outwards. A segment 4 may be carried by inclined links 6 having cylindrical ends engaging recesses in the segment and in a stationary ring 2. The segment is pressed inwards by a spring 8 located by a pin 10 engaging a hole in the segment and a slot in the ring 2. The spring 8 may be dispensed with, the links being formed as springs 12, secured by pins 15, and having out-turned ends engaging the segment and the ring 2. The links may be replaced by inclined slots 16 in the segments engaging stationary pins 17. In a modification, the spring 22, which presses the segment inwardly, takes its abutment on a pin 19, the head of which enters a recess 29 when the segment is moved circumferentially against the action of a spring 20. When the packing rings co-operate with the radial surfaces of collars on the shaft, the surfaces of the collars are bevelled, in order that the radial movement of the packing rings may increase the axial clearance.
