Abstract: A method and apparatus for positioning an object in space in such a manner as to permit duplication of the positioning in a precise position wherein three characteristic points on the object wherein the coordinates of the points are determined and are electrically synthesized for generation of a signal for reproducing the points on the coordinates, and utilizing a television camera and monitor forming an image of the object on the screen and causing the points of the object to coincide with the reference points by means of a photosensitive sensor in such a manner that the characteristic points on the body are displaced so as to coincide with the synthesized points on the television screen.

Abstract: Textile strands or threads with no twist at least partially coated by wax are formed by immersion in a molten wax while in a false twisted state. The coated strands or threads are then cooled and the wax solidifies.

Abstract: Quaternary ammonium salts of malic acid having the formula: ##EQU1## where: R is a monovalent aliphatic hydrocarbon radical, saturated or unsaturated, of from 8 to 20 carbon atoms but preferably of 12 to 18 carbon atoms; R.sub.1, R.sub.2, R.sub.3 may be identical or different and each represents a lower alkyl radical or an aryl radical. The salts find use in cosmetics as a source of the malic ions necessary to the energy process in cellular metabolism. These salts insure a better intracellular penetration of malic ion and improve the stability of creams and other cosmetic emulsions.
