Title: Improvements in or relating to multi-cylinder shed forming machines
IPC: D03C3/16
Filed: 1939-05-06
Abstract: 528,855. Loom shedding mechanism. STAUBLI, H. Sen., STAUBLI, H. Jun., STAUBLI, R., STAUBLI, H. H., and STAUBLI, O., (trading as GEB. STAUBLI & CO.). May 6, 1939, No. 13581. Convention date, Dec. 13, 1938. Addition to 498,952. [Class 142 (i)] Relates to multicylinder shed-forming mechanism having pasteboard or paper pattern cards A<SP>1</SP>, A<SP>2</SP> carried by cylinders a<SP>1</SP>, a<SP>2</SP> and means for reopening in correct sequence the woven-in wefts both in forward and backward weaving. Instead of providing a control element for governing the counting cylinder controlling the mechanism for changing from one cylinder to the other (a change perforation or projection) at the commencement and end of each repeat as is done in the parent case, the usual pattern cards each with a single control element are used, this element being however read off successively by two members or change needles l<SP>1</SP>, l<SP>2</SP>. When changing over from one cylinder to the other, the reading is effected by one feeler member on one cylinder, but by the other feeler member in the other. In one arrangement, needles l<SP>1</SP>, l<SP>2</SP>, for reading the change holes are connected to respective lifters k each furnished with a wire i with a bent end projecting into a vertical slot d in an arm c. The two arms c are fixed to a shaft b and have slots e receiving catches f pivoted on constantly swinging arms g. Normally the catches f do not engage the wires i, but if one of the needles l<SP>1</SP> or l<SP>2</SP> falls into a change hole of the pattern card A<SP>1</SP> or A2, the corresponding lifter k and wire i move downwards, the latter being engaged by the corresponding catch f, the shaft b turned and the counting cylinder actuated. In another arrangement described a single lifter is used pivotally carrying a wire from which the two needles are suspended. In another arrangement described, each of the cylinders has its own pair of change needles.

IPC: C09B3/12
Filed: 1926-05-31
Abstract: 278,047. Johnson, J. Y., and I. G. Farbenindustrie Akt.-Ges. May 31, 1926. Addition to 203,533. 2: 2<1>-Dibenzanthronyls are obtained by treating with alkaline condensing agents under moderate conditions mixtures of 2-halogenbenzanthrones with benzanthrones having a free 2-position. The reaction takes place more readily than that of the parent Specification and also renders possible the production of unsymmetrically substituted 2 : 2<1>-dibenzanthronyls. Any dyestuffs formed simultaneously may be extracted with alkaline hydrosulphite solution. According to examples the following compounds are produced :- (1) 2 : 2-dibenzanthronyl from benzanthrone and 2-chlorbenzanthrone by action of sodium anilide in aniline; (2) 6-methyl-2 : 2<1>-dibenzanthronyl from 2-chlorbenzanthrone (Specification 222,125) and 6-methylbenzanthrone by action of sodium anilide in aniline, or of isopropyl alcohol and caustic potash in toluene; (3) 6- or 7-chlor-2 : 2<1>- dihenzanthronyl from 2-chlorbenzanthrone and 6- or 7-chlorbenzanthrone; (4) 6-chlor-2: 2'-dibenzanthronvl from benzanthrone and 2 6-dichlorbenzanthrone in presence of potassium anilide; (5) 6 : 6<1>- or 7 : 7<1>-dichlor-2 : 2<1>-dibenzanthronyl from 2 : 6-dichlorbenzanthrone and 6- chlorbenzanthrone or 2 : 7-dichlorbenzanthrone and 7-chlorbenzanthrone. The condensations are carried out in a current of nitrogen. 2 : 6-Dichlor- and 2 : 7-dichlorbenzanthrones are respectively obtained by condensing 2 : 6- and 2 : 7-dichloranthraquinones with glycerol in presence of sulphuric acid and a reducing agent.

IPC: H01H19/20
Filed: 1955-05-12
Abstract: 827,283. Screw-and-nut gearing. PAINTON & CO. Ltd. May 14, 1956 May 12, 1955], No. 13761/55. Class 80 (3). [Also in Groups XXXV, XXXVI, XXXVII and XL (c)] In a mechanism for translating rotary into helical motion, end stops are provided by a pin which moves axially in stopped slots in a rotating member. In the multi-turn potentiometer shown (see Group XXXVI) the member 6 is driven over resistive and collector helices 2, 3 respectively by a nylon nut 5 which has a moulded three-start thread to fit that of the lead screw 7 but provides sufficient friction to prevent undesired rotation. The nut is rotated by a fork 25 attached to a stainless steel boss 29 having a key 30 which is screwed into the mounting bush 9. The key 30 engages a slotted head 34 at the end of the operating spindle 23. A pin 35 in the key 30 protruding into the stopped slots 36 in the head 34 provides end stops since rotation of the spindle 23 screws the key 30 along the axis of the bush 9 causing the pin 35 to move axially until the ends of the slots 36 are reached. The mounting bush 9 is retained in the body by a flange 37 which fits into grooves moulded into the body. In a modification (Fig. 4, not shown), instead of the edges of the key 30 being threaded, the pin 35 protrudes through the slots 36 and has threads cut in its ends which engage those on the mounting bush 9.

Filed: 1945-06-04
Abstract: 592,787. Prepayment gas meters. BEGWACO, Ltd., and THORP, F. June 4, 1945, No. 13970. [Class 27] The mechanism which usually actuates a gas cut-off valve is arranged instead to operate a shutter or shutters associated with two indicators, one for showing credit and the other debit, so that the appropriate one of the two indicators is exposed according to whether the mechanism is in credit or debit and the other masked. As shown a duplex shutter k is carried on the end of a lever pivoted at n to move vertically in front of a pair of indicators i and j showing respectively credit and debit. Attached to the opposite end of the lever is a rod q with a projection bearing on the periphery' of a cam s under the action of a spring t. The cam s is driven by a geneva motion v, similar to that usually provided for actuating the gas valve control mechanism and driven in opposite directions by the prepayment and meter mechanisms through an epicyclic quantity mechanism. The drive to the indicators is taken from the driving element of the geneva motion by way of gears f, g and h. As the mechanism passes through zero credit in either direction, the cam s moves the shutter up or down to expose the appropriate indicator i or j and mask the other. Specification 568,581 is referred to.

Title: Improvements in or relating to vitamin b
Filed: 1957-05-03
Abstract: The invention comprises a complex between Vitamin B12 and zinc-cuprocyanide, which is substantially water-insoluble, has a pink colour, is stable to treatment with most common organic solvents, is soluble in dimethyl formamide and may be precipitated from the solution thereof by adding acetone, and may be split up to form Vitamin B12 by treatment with an aqueous solution of a chelating and complexing agent known to give a complex salt with zinc, and a process for the production of highly pure Vitamin B12 which comprises forming zinccuprocyanide in a dilute solution of Vitamin B12 and any associated impurities by reacting a water-soluble cuprocyanide with a water-soluble zinc salt so as to precipitate a zinccuprocyanide Vitamin B12 complex, the remaining material staying in solution and recovering the highly pure Vitamin B12 from the precipitated complex by decomposing the complex.  As water-soluble cuprocyanide there may be used tripotassium cuprocyanide which may be reacted with zinc sulphate or zinc acetate.  The Vitamin B12 complex may be decomposed by means of a chelating agent such as the sodium salt of ethylene diamino tetra-acetic acid, the sodium salt of N-hydroxy-ethyl-ethylene diamino triacetic acid or the sodium salt of nitrilo triacetic acid in an organic solvent such as amyl alcohol, butyl alcohol, isobutyl alcohol, a phenol or a mixture of phenol with a halogenated hydrocarbon.  Subsequently the organic solution of Vitamin B12 is extracted with water and the Vitamin B12 is precipitated by adding another organic solvent in which the Vitamin B12 is insoluble.  Examples describe the production of zinc cuprocyanide-Vitamin B12 complex and the recovery of Vitamin B12 from fermentation broth. Specification 816,425 is referred to.
