Title: Improvements in the manufacture of amino compounds of the anthraquinone series
IPC: C07C225/34
Filed: 1937-01-20
Abstract: Amino or aliphatically substituted amino derivatives of anthraquinone are manufactured by reacting with ammonia or an aliphatic amine, in the presence of a compound of a heavy metal or of a metal capable of forming a complex nitrogenous compound with a nitrogenous base, and in a reaction medium which consists, apart from the reactants, substantially entirely of a dilute aqueous solution of caustic alkali, an anthraquinone compound which is at least slightly soluble in dilute aqueous solutions of caustic alkali and which contains a hydroxy, amino or substituted amino group in the 1- and 4-positions of the anthraquinone nucleus.  The process is applicable to the treatment of hydroxyanthraquinones or of amino or substituted amino derivatives of anthraquinone which are at least slightly soluble in dilute aqueous solutions of caustic alkali.  Suitable aliphatic amines, i.e. amines containing an amino group not directly attached to an aryl residue, are those specified in the parent Specification, and also a  : g -diaminopropane.  Suitable metal compounds are the salts, oxides or hydroxides of manganese or copper, whilst the caustic alkali solution may be a 0,5-5 per cent solution of caustic soda or caustic potash.  In examples, the following materials are heated in dilute caustic soda solution: (1) quinizarin, methylamine and copper sulphate, yielding 1 - methylamino - 4 - hydroxyanthraquinone; (2) as in (1) except that the amount of methylamine is larger, whereby 1 : 4-dimethylaminoanthraquinone is formed; (3) quinizarin, monoethanolamine and manganese chloride, producing 1 : 4 - di - (hydroxyethylamino) - anthraquinone; (4) as in (3) except that the amount of monoethanolamine is reduced, whereby 1-hydroxyethylamino-4-hydroxyanthraquinone is obtained; (5) 1 : 4 : 5-trihydroxyanthraquinone, monoethanolamine and copper sulphate, yielding 1 : 4-di-(hydroxyethylamino)-5-hydroxyanthraquinone; (6) 1 : 4 : 5 : 8-tetrahydroxyanthraquinone, monoethanolamine and copper sulphate, producing 1 : 4-di-(hydroxyethylamino) - 5 : 8 - dihydroxyanthraquinone.  Other starting materials specified are 1-amino-4 : 5 : 8 - trihydroxyanthraquinone, 1-hydroxy-4-aminoanthraquinone and 1-hydroxy-4-methylaminoanthraquinone.

Patent GB-492439-A (GB)
Title: Improvements in or relating to rubber and the like processes and products
IPC: B29D99/00
Filed: 1937-01-20
Abstract: Relatively inextensible rubber thread is made by extruding filaments through adjacent nozzles into a coagulating bath, so that they unite on being drawn through the bath, one or more of the filaments being formed from latex or like dispersion, and one or more from or containing sufficient glue, gelatine or the like to produce a thread capable of being knitted or woven into a fabric to which extensibility can be restored by the removal of the extensibility reducing agent.  A central nozzle may extrude concentrated latex while surrounding nozzles extrude latex to which sufficient glue, suitably 25 per cent on the dry rubber content, has been added to give an inextensible thread.  Numerous arrangements and modifications are described including an annular nozzle surrounding a central nozzle, and a cluster of nozzles capable of being rotated, or moved to form a braided thread.  When any of the nozzles extrudes glue alone, the coagulant is preferably alcohol or the like.  The thread may be stretched while the glue is still moist, or in the presence of steam or other solvent vapour, and dried.  This thread will retract on removal of the extensibility reducing agent.  The diameter may be reduced by stretching and heating while maintaining the tension, to relieve internal stresses.  An outer coating of extensibility reducing agent may be applied to the thread after drying, as may also a textile wrapping.  Specifications 441,124, 449,314, 459,434, 469,433, and 477,523 are referred to.

Abstract: 660,379. Apparatus for applying screwcap stoppers. SALES, H. A. Jan. 27, 1950 [Jan. 27, 1949], No. 2213/49. Class 125(ii) In a machine in which a cap is screwed on to a bottle, jar or the like by placing the cap between a rotating disc and an adjacent member having a limited sideways movement for tightening the cap, the said member is arranged for pivotal movement away from the disc after the cap has been finally tightened onto the bottle or jar, so that the latter may be withdrawn from the machine. A pin 10 carried by lugs 7 at one end of a member 5 passes through a slot 9 in a bracket 8, the member 5 being thus capable of limited sliding and pivotal movements. The other end of the member 5 carries a pin 12 for pivotally mounting between its forked ends a block 11. The latter is urged by a leaf spring 13 to normally lie squarely on an anvil part 16 while a cap 18 which has previously been screwed onto the neck of a bottle is placed between a rotating disc 4 and a rubber strip 6 fixed to the member 5. The bottle is held by hand, or other means, and the cap 18 rolls on the strip 6 to screw the cap firmly onto the bottle after which the disc 4, the cap 18 and the member 5 become locked together and the member 5 moves .sideways until the block 11 drops over the anvil 16. This allows the member 5 to pivot away from the disc 4 and the bottle can then be removed from the machine.
