Patent GB-363740-A (GB)
Title: The manufacture of fast vat dyestuffs
Filed: 1930-10-06
Abstract: Anthraquinone and anthrone derivatives.--One molecular proportion of a polynuclear aromatic compound containing in at least each of two of the nuclei at least one reactive hydrogen atom attached to the nucleus, is condensed with two molecular proportions of an anthraquinone-2-carboxylic acid halide containing in the 1-position an amino group or in the 1,9-positions a heterocyclic ring, in the presence of an anhydrous metal halide of the Friedel-Crafts type. Alternatively one molecular proportion of the polynuclear aromatic hydrocarbon is first condensed with one molecular proportion of the anthraquinone-2-carboxylic acid halide derivative and the resulting monoketone is further condensed with one molecular proportion of the same or a different anthraquinone-2-carboxylic acid halide derivatives, both condensations being effected in the presence of an anhydrous metal halide of the Friedel-Crafts type. The products are diketone derivatives which dye fast bright orange to red shades from the vat.  Suitable anhydrous metal halides are aluminium chloride, sodium-aluminium chloride, ferric chloride and stannic tetrachloride and they may be used alone as molten salts or in the presence of solvents or diluents.  The two-stage process has in some cases the advantage of yielding a particularly pure product.  In examples (1) pyrazolanthrone-2-carboxylic acid chloride (see Specification 332,316, [Class 2 (iii), Dyes &c.], (two mols.) is condensed with diphenyl (1 mol.) by means of sodium-aluminium chloride: (2) thiazolanthrone-2-carboxylic acid chloride (see Specification 355,597) (two mols.) is condensed with diphenyl (one mol.) as in (1), or one mol. of the acid chloride may be condensed by means of aluminium chloride in nitrobenzene and a second mol. condensed with the resulting monoketone by means of sodium-aluminium chloride: (3) thiophenanthrone-2-carboxylic acid halide (see Specification 349,080) (two mols.) is condensed with diphenyl (1 mol.) as in (1): (4) thiazolanthrone-2-carboxylic acid chloride (two mols.) is condensed with diphenyleneoxide (1 mol.) by means of sodium-aluminium chloride; or the diphenyleneoxide may be replaced by diphenylether: (5) thiazolanthrone-2-carboxylic acid chloride (one mol.) is condensed with diphenyl (one mol.) by means of aluminium chloride in nitrobenzene, and the monoketone derivative condensed with one mol. of pyrazolanthrone-2-carboxylic acid chloride by means of sodium-aluminium chloride: (6) 1-aminoanthraquinone-2-carboxylic acid chloride (two mols.) is condensed with diphenyl (one mol.) by means of sodium-aluminium chloride, or the condensation may be carried out in two stages similar to that described in (2); instead of diphenyl there may be used diphenylether, naphthalene, 2.4-diphenylthiazole or 2.4.6-triphenyl-1.3.5-triazine.  The use of anthrapyridone-2-carboxylic acid halides and of N-ethylcarbazole (as polynuclear aromatic compound) is also mentioned.

Filed: 1958-09-25
Abstract: 841,814. Door operating-appliances. MUIRHEAD, L. A. Sept. 25, 1958, No. 30632/58. Class 65(1). A garage door is operated by a pair of springs, one for opening and one for closing the door, of such relative strengths that opening the door by means of one spring supplies potential energy for closing the door by the other. The sequence of operations is open door manually, close door mechanically, open door mechanically and close door manually, so that there is no need to leave a non-garaged car to operate the door. Adjustable bell cranks 16, 17, 19, 20 are connected by links 1A, 2A to the doors 1, 2 and by links 15, 18 to arms 6, 14 commonly pivoted at 7. Arms 10, 23 are also pivoted at 7 and are acted on by springs 13, 24 respectively. The ends of arms 10, 23 engage in spring pressed ratchet arms 8, 22 respectively. Arm 6 carries a part 5 moving under the control of a Bowden cable or hydraulic means longitudinally outwards of arm 6 and designed to move the adjacent ratchet arm away from the arm 10 or 23 with which it is engaged. Fig. 1 shows the apparatus before the first operation. Manually opening the doors swings the arms 6, 14 to rest against arm 10. The doors are then closed by operation of e.g. lever 3 which moves part 5 against ratchet arm 8, releasing arm 10 which under the action of spring 13 swings over, carrying with it arms 6, 14 to rest on arm 23 (Fig. 4). Operation of control 3 then releases arm 23 from ratchet 22 and spring 24 acting against spring 13 swings arm 23, together with arms 6, 14 and 10, over against arm 8, causing arm 10 to engage with ratchet arm 8. Thus the doors are opened and simultaneously spring 13 is tensioned for mechanically closing the doors. Finally the doors are manually closed and arms 6, 14 are swung to the position shown in Fig. 1.

In a machine for washing churns in which the churns are carried inverted through successive washing, rinsing and other stations by an endless conveyer, each churn as it topples over at the delivery end of the conveyer is received by a cradle which turns it over and deposits it on a rest which lowers it to an upright position, mouth upwards, on a support from which it is pushed forward on to a second conveyer by one or more pivoted arms which are turned intermittently by cam means driven by the endless conveyer driving means. As shown, the inverted churns at the delivery end of the endless conveyer 3 are received by a cradle 1 on a shaft 1A driven from the conveyer driving shaft 2, and deposited in an upright position on a rest 16 by which it is lowered slowly on to a platform at 20. The churns are pushed from this platform on to another conveyer (not shown) by a pair of arms 11 fixed on a shaft 10, these arms being rocked by a cam 8 engaging a finger 9 on the shaft 10. The cam 8 is mounted at one end of a lever 4 which is rocked about a shaft 5 by a cam 7 engaging a cam surface 6 at the opposite end of the lever 4, the cam 7 being fixed on the conveyer driving shaft 2. The churn lids are fed along a runway 18A by a reciprocating carriage 17 working in synchronism with the conveyer 3, and slide down an incline 25 to a pivotally mounted holder 22 from which they are allowed to fall on to the mouth of the churns. The position of the holder is determined by a slidable rod 26 which is controlled by a pivoted arm 14A actuated by the cam 14. Specification 592,428 is referred to.

Patent GB-230187-A (GB)
Title: Improvements in and relating to the treatment of cellulose artificial silk
IPC: D06M15/11
Filed: 1923-12-07
Abstract: Cellulose artificial silk, that is, viscose silk, cuprammonium silk and nitrocellulose silk, is caused to contract in length and at the same time to suffer a decrease in lustre so as to approach in appearance natural silk, by first treating with a protective sizing-agent such as gelatin, albumen or starch, then with caustic alkali solution of at least 18 per cent strength, and finally with dilute acid in such manner as to remove the alkali rapidly.  The effect produced depends on the degree of tension employed, being the greatest when no tension is applied.  The protective action of the sizing-agent may be assisted by the addition of glycerine to the caustic alkali solution; and if the silk is to be treated after scouring, bleaching or "wetting out," the protective agent may be rendered insoluble by the addition of aluminium acetate to the sizing-material.
