Patent ZA-826126-B (ZA)
Title: Reaction injection molding process
Inventor: EWEN JAMES HAROLD
IPC: C08G18/00
Filed: 1982-08-23
Abstract: The use of certain prepolymers of 4,4'-methyienebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages par- ticuiariy when the compositions are prepared by reaction injection molding techniques using two streams of reactants. The principal advantages are (i) a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1:1.This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time. The prepolymers of 4,4'- methyienebis(phenyi isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10.000), polytetramethylene glycols (MW = 600-5.000) and polyester diols and triols (MW = 500-8.000).

Title: Dioxolane derivatives
IPC: C07D317/34
Filed: 1981-03-05
Granted: 1984-01-25
Abstract: The invention is concerned with novel dioxolane derivatives of the formula:   <IMAGE> I  in which Ra is hydrogen or (1-4C)alkyl and Rb is (1-4C)alkyl or phenyl optionally bearing a halogeno substituent; their production; and their use for the manufacture of certain known anti-arthritic acids of the formula:   <IMAGE> V  and, in particular, those acids in which Ra=Rb=methyl or Ra=ethyl and Rb=phenyl, by a novel reduction process. The preferred reduction procedures involve the use of an alkali metal borohydride or cyanoborohydride in the presence of a noble metal catalyst, or the use of an  alpha -branched alkyl or cycloalkyl Grignard agent. The use of the derivatives of formula I avoids the need for potentially toxic reagents and reactive intermediates in the previously known processes for the production of the acids of formula V.

Title: A method of endrounding loose fibres
Inventor: BOUCHERIE BART GERARD
IPC: A46B9/02
Filed: 1997-08-12
Granted: 2001-11-07
Abstract: For implant molding of toothbrushes pre-cut and pre-rounded fiber of thermoplastic material are used. Loose fibers are presented to an endrounding tool in a tuft or bundle and the free ends of the fibers are exposed to a working surface of the tool. Relative movement between the fiber ends and working surface causes the material of the fibers to be heated by friction of a predetermined intensity. The fibers while they are exposed to the working surface of the tool are permitted to flex laterally and are held in an axial direction of the tuft or bundle with their free ends commonly defining a surface different from a plane which is perpendicular to the axial direction, thereby achieving a substantially consistent flexing resistance throughout the cross-section of the tuft or bundle with respect to lateral deflection upon engagement by the endrounding tool.
