Abstract: 1387131 Electric cells GATES RUBBER CO 8 May 1972 [10 May 1971] 21360/72 Heading H1B A method of producing a wound electric cell comprises folding over end 20 of a flexible tab 18 secured to an assembly 10 of electrode strips 12, 14 and spacer material 16 to be wound, curling the tab 18 from the folded over end as at 24, bringing the curled portion into contact with a mandrel 26 having provision in its peripheral surface for receiving the end of tab 18, rotating the mandrel in the direction of the curl thereby uncurling the tab until folded end 20 engages the receiving means and continuing rotation, preferably at a higher speed to wind the assembly 10. The cell may be a rechargeable alkaline cell, e.g. a small nickel-cadmium or nickel-zinc cell. Preferably, the end is curled over at least four turns, e.g. by applying heat or steam. As shown, the receiving means is formed by splines 28 on the mandrel, but it may alternatively have a saw-tooth or star-wheel configuration. The strips to be wound may pass between a pair of idling rollers to the mandrel which may be a driven mandrel or a winding roller may bear on the roll. On completion of winding the mandrel is withdrawn and the void filled by e.g. a spiral spring or a porous plastics sleeve which leaves space for recombination of gases evolved during cell operation. The tab may alternatively be formed as an extension of a separator strip.

Title: Organic arsenic compounds
IPC: C07F9/74
Filed: 1934-07-25
Abstract: Organic arsenic compounds of the general formula R--O--R<1> in which R is an aromatic nucleus carrying arsenic as a direct substituent with or without other substituents, and R<1> is a substituted or unsubstituted alkyl group containing one or more alcohol groups, are prepared by reacting an arsenic substituted phenol with an alkylene halogen hydrin or an aryl substituted alkylene halogen hydrin. Substituent groups which may be attached to the radical R include amino, substituted amino, nitro, sulpho and halogen groups.  The arsenic attached to the aromatic nucleus may be tri-valent or pentavalent.  Examples given include the groups --AsO3H2, --AsO, --As(SCH2.COOH)2, --As(SCH2.COOX)2 and --As = As--, where X is H, a metal, or a salt forming group.  In examples: (1) p-arsonophenoxy-ethanol is prepared by the addition of the sodium salt of p-hydroxy-phenylarsonic acid to ethylene chlorhydrin, followed by refluxing for four hours.  In a similar manner the corresponding ortho and meta compounds, o-arsono-phenoxyethanol, and m-arsono -phenoxyethanol may be prepared.  (2) 4-arsonophenoxypropanol is prepared by refluxing the sodium salt of 4-hydroxyphenylarsonic acid with trimethylene chlorhydrin.  In a similar manner 4-arsono-2-nitro-phenoxypropanol, and 4-arsono-2-nitro-phenoxypropanol nitrate are prepared.  The compounds of the present invention are of therapeutic value for treating trypanosome or spirochete infections.
