Title: New polyazo-dyestuffs and process for making them
IPC: C09B45/48
Filed: 1955-04-13
Abstract: The invention comprises dyestuffs of formula <FORM:0784879/IV (b)/1> where R1 is a benzene residue containing -OH p to -N=N- and -COOH o to the -OH, R2 is a benzene residue bound in p-position to the azo links, R3 is a benzene residue bound in p-position to the azo links and having an hydroxy group in the o-position to the azo link bound to the naphthalene residue and X is NH2 or an acylamino group. Preferably the dyestuffs contain only one SO3H group.  They are made by demetallizing the corresponding metal derivatives in which the two OH groups adjacent the azo link connected to the naphthalene residue are metallized, these metal complexes being obtained by metallizing with dealkylation a corresponding dyestuff in which R3 contains an alkoxy group adjacent to the azo link connected to the naphthalene residue.  Preferably, metals of atomic member 27-29, especially copper, are used.  The o-alkoxy, o1-hydroxy dyestuffs are made by coupling a diazo compound of an amine of formula R1-N=N-R2NH2, preferably in a weakly acid medium, with an amine of formula HR3(o-alkyl)NH2, diazotizing the product and coupling in an alkaline medium with an appropriate naphthol end components.  Specified amino-monoazo dyestuffs are 4-amino-41-oxy-1,11-azobenzene-31-mono- and 3,31-di-carboxylic acids, 2-chloro-, 2- and 3-methyl- and methoxy-, 2,5-dimethyl- and -dimethoxy-2-methyl-5-methoxy- and 51-methyl- and -chloro-4-amino-41 - oxy - 1,11 - azobenzene - 31 - carboxylic acids; o-alkoxy amines specified are 2-methoxy-, -ethoxy-, 2-methoxy and -ethoxy-5-methyl-, 2,5-dimethoxy- and -diethoxy- and 2 - ethoxy - 5 - methoxy - aniline; 2-acetylamino- and -amino-8-naphthol-sulphonic acids are specified end components. Both metallization and demetallization are carried out by conventional methods.  The dyestuffs dye animal fibres such as wool, silk and leather, but are particularly of use in dyeing cellulosic fibres such as cotton, linen and artificial silk or staple fibres of regenerated cellulose.  The dyeings are preferably metallized, especially coppered, e.g. as in Specification 455,274, [Group IV], and after-treated as in Specification 619,969.  Examples and a Table are provided illustrating the preparation of the dyestuffs from certain of the above specified components and their use in dyeing cotton in black shades by an after-coppering process.

Patent GB-441119-A (GB)
Title: Improvements in or relating to the manufacture of polynuclear compounds
IPC: C09B3/78
Filed: 1934-04-10
Abstract: Polynuclear compounds are prepared by fusing a "mono- or di-ketone of the anthracene series" with a metallic halide condensing agent, e.g. aluminium chloride or sodium-aluminium chloride, preferably in presence of an oxidizing-agent such as manganese dioxide, potassium chlorate, oxygen or air.  A "mono-or di-ketone of the anthracene series" describes a  - monoaroylanthracenes, a  . a  - diaroylanthracenes and a  . meso - diaroylanthracenes.  These starting materials are prepared by converting the corresponding acids to the acid chlorides and condensing these with an aromatic hydrocarbon in presence of a metal halide condensing agent.  The 1.10-diaroylanthracene is obtained by treating the 1-aroylanthracene with benzoyl chloride in presence of aluminium chloride.  In examples: (1) 1.4-anthracene dicarboxylic acid is treated with phosphorus pentachloride and then with benzene in presence of aluminium chloride; the resulting 1.4-diaroylanthracene is condensed with sodium aluminium chloride in presence of oxygen to give a pyrene - quinone derivative; (2) 1.5-anthracene dicarboxylic acid (prepared by reducing the 1.5-anthraquinone dicarboxylic acid with zinc and ammonia) is treated with phosphorus pentachloride and then with benzene as in (1); the 1.5-diaroyl body so obtained is condensed by means of aluminium chloride in presence of manganese dioxide to give a dibenzperylenequinone (dyes reddish violet); (3) a -anthracene carboxylic acid is treated with phosphorus pentachloride in benzene, aluminium chloride added and the mass heated to 50 DEG  C. to give 1-benzoylanthracene; this is further condensed in nitrobenzene and in presence of aluminium chloride with benzene at 60 DEG  C. and the resulting 1.10-dibenzoylanthracene heated with sodium aluminium chloride at 160--180 DEG C., if desired in presence of oxidizing agents to give probably a mixture of a pyrenequinone and a perylenequinone.

Title: Improvements in the cracking or pressure hydrogenation of hydrocarbons
IPC: C10G47/00
Filed: 1938-04-08
Abstract: 524,380. Cracking and destructive hydrogenation of hydrocarbons. JOHNSON G.W. (I. G. Farbenindustrie Akt.-Ges.). April 8, 1938, No. 10847. [Class 32] In the catalytic conversion, e.g., cracking or pressure hydrogenation, of carbons rich in hydrogen i.e., containing more than 15 grams of hydrogen per 100 grams of carbon, a highly active catalyst is employed the activity of which has been reduced e g., by about 25 per cent., by prior use in the catalytic conversion of hydrocarbons poor in hydrogen. Catalysts specified for subjection to such treatment comprise (1) for pressure hydrogenationheavy metal sulphides (2) for cracking- substances containing both silicic acid and alumina e.g., aluminium hydrosilicates. In an example, a tar oil boiling about 200-400‹C. is led at 410‹C. with hydrogen under a pressure of 200 atmospheres, with a partial pressure of tar oil of 13 atmospheres, over a rigidly arranged tungsten disulphide catalyst for 3 days, and the catalyst thereby reduced in activity by about 25 per cent., is employed for the conversion, at the same temperature and pressure, of a 200-325‹C. fraction of a hydrocarbon mixture obtained bv the reduction of carbon monoxide, yielding 70 per cent. benzine and by 6 per cent. gaseous hydrocarbons.

Title: Film Mounters
Inventor: DEDONA FRANCIS ALFRED
IPC: G03D15/10
Filed: 1967-03-08
Abstract: 1,176,571. Mounting films on cards. SCIONICS CORP. March 8, 1967, No. 10936/67. Heading G2C. In a machine for mounting a film section on an apertured card, the section is trimmed and cut-off from a continuous film web by a pair of transverse cutting elements. The machine is built up on a base-plate 10A, and has two vertical side plates 10B, 10C connected by cross-bars 10D, 10E. The cross-bars support a pair of slotted vertical members 10F, 10G, the slots 10H and 10I acting as a guide for the film web F. A pair of channelled members 13, 14 can move into engagement with the edges of the film to guide it across from slot 10I to 10H, but are retracted during the actual cutting operation. The apertured card C is positioned manually in a support 10U, the aperture being covered by an adhesive sheet S to which the film is bonded, either with or without heating. The film F is fed into position by a roller 12 operated by a knob 11G, and located accurately by means of an illuminated cursor wire 43. The film section is then cut-off and applied to the sheet S by mechanism actuated by pulling a lever 30. Behind the card C and sheet S is a pressure pad 20G having an inner flanged portion 20J which, during the applying operation, is brought into contact with sheet S to support it Fig. 3 (not shown). Pad 20G may have a heating element, controlled by a thermostat 20P, and is carried by arms 20A, 20B pivoting on a shaft 10X. The cutting element is formed by a rectangular frame 17 secured to two arms 17C, 17D also pivoting on shaft 10X. The actual cutting edges are the vertical members 17A, 17B of frame 17, which exercise a shearing action on the film F when co-operating with the stationary film guides 10G, 10F respectively. Cutter 17A severs the film section from the rest of the web, and at the same time cutter 17B trims the other edge of the severed section. The lever 30 is mounted on a shaft 30B which is journalled in the fixed frame plates 10B, 10C, the shaft also mounting a pair of plates 30C, 30D. Between these plates is a cam plate 20D mounted on a cross-bar 20C connecting arms 20A, 20B. The upper part of cam plate 20D has an arcuate slot, in which engages a cam roller 30E secured between plates 30C and 30D. Thus when lever 30 is pivoted clockwise, as seen in Fig. 6, roller 30E moves into the arcuate slot and hence causes plate 20D, and hence arms 20A and 20B, to pivot counter-clockwise. Thus backing pad 20G is pivoted so that its flanged part 20J contacts and provides a backing support for the sheet S. The same movement of plates 30C, 30D causes a clockwise movement of arms 17C, 17D, since these are connected via an eye bolt 17J and a spring 17H to an anchor pin 30F. Thus frame 17, which is carried by arms 17C, 17D, is pivoted forward to cut the film (see also Fig. 4, not shown), and then continues its forward motion to press the severed film section against the sheet S in the apertured portion of the card (see also Fig. 5, not shown). Figs. 15-23 (not shown) illustrate alternative forms of cutter elements.

[Also in Group XXXIV] A high-speed twist-apparatus for false-twisting a linearly-travelling yarn, comprises at least two supporting-members mounted for rotation in speed relation to each other and a continuouswalled twist-tube freely suspended by and rotatable between them, yarn guide-means positioned in the path of the yarn carried by the tube, one of the supporting-members having means for driving the tube whereby the angular velocities of the tube and member vary inversely as their respective radii. In Fig. 1, the tube 46 is carried by three belts 51-53 around pulleys 31, 43, 44, the pulley 31 being carried by a shaft in bearings 25, 26 and rotated by a belt 23. The idler pulleys 43, 44 are carried by a shaft the bearings of which are carried by an eccentrically-bored sleeve-member clamped in a housing by screws 39; the position of the eccentric can be varied by a lever to tighten the belts 52, 53. The twist-tube can have crowned rings 47, 49 which may have flanges. In Fig. 4, the tube is supported directly by three pulleys one of which is driven and carried by a pivoted arm 77 urged by a spring into contact with the tube. The two idler pulleys may have rings of rubber co-operating with grooves in the spindle. The bearings of the various pulley-shafts are held in their seatings by resilient split-rings of polygonal shape with a large number of flats, which rings are disposed in circumferential grooves in the seatings. The spindle is provided at the top or bottom with a detachable housing for a roller guide 56 which may be offset from the spindle-axis and around which the yarn is wrapped once or twice: alternatively, two rollers 114, 115, Fig. 7, may be mounted on oppositely-inclined shafts on opposite sides of the central axis of the tube so that the yarn reaches the lower roller and leaves the top roller tangentially along aligned paths. The rollers may be replaced by non-rotational tubular or other elements and both may be offset on the same side of the spindle axis for the yarn to be wound around each element in the same direction.
