Abstract: A compound comprising a cyclopentanone, cyclopentenone, cyclohexanone or cyclohexenone group, wherein a first ring carbon atom carries an —SR substituent, R is a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group that, optionally, includes at least one heteroatom in its carbon skeleton, the remaining available ring carbon atoms are optionally substituted, and said compound either: —(a) is more soluble in water at a temperature of 20-40° C.; (b) is less lipophilic; and/or, (c) has a greater therapeutic index; or; (d) is less soluble in water at a temperature of 20-40° C.; (e) is more lipophilic; and/or, (f) has a greater therapeutic index; than an equivalent cyclohex-2-en-1-one or cyclopent-2-en-1-one derivative in which a hydrogen atom replaces said —SR group.

Abstract: A multi-position electrical connector for a robotic tool changer includes a bracket mountable to a robotic tool changer master or tool module, a coupling interface in a fixed position with respect to the bracket, and a cable interface moveable to a plurality of positions with respect to the bracket. Both the coupling interface and the cable interface include a plurality of electrical contacts, which are electrically connected. In one embodiment, the cable interface is disposed at substantially 90 degrees to the coupling interface, and is rotatable about an axis of the coupling interface. The cable interface may be fixed in one of a plurality of positions around the coupling interface. In one embodiment, a selected position is fixed by mating a retention member on one of the cable interface and the bracket, with a recess on the other of the cable interface and the bracket.

Abstract: Kaolin is added to the insulation (30) in a metal sheathed, mineral-insulated cables of the type used as a power cable, heating cable, or thermocouples where high temperature and an aggressive medium may exist, and which are typically produced by drawing down the cable. The preferred insulation for the invention is MgO. The addition of kaolin decreases moisture seepage into the insulation and consequent drop in insulation resistivity. It also reduces the loss of electrical resistance as temperature increases.
