Patent number: 4440800Abstract: A liquid or powder material can be dispersed by the application of electrostatic fields. The phenomena, referred to as "electrodispersion" is the dispersion by an intense electric field of part of a static bed of liquid or powder into a stable cloud of rapidly moving particles, and the maintenance of a dynamic equilibrium between the static and dispersed phases. The density of the dispersed cloud of particles varies with a number of factors, including the field strength and the nature of the powder. The electrodeposition effect is employed to produce a uniform and durable coating of controlled thickness on the individual particles, by the generation of a vapor of the desired coating--typically a metal or semiconductor material--and allowing the vapor to permeate the dispersed particles. The electric field ensures that only the particles are coated, and the dispersed particles, having the same charge, repel each other, avoiding agglomeration.Type: GrantFiled: April 16, 1981Date of Patent: April 3, 1984Assignees: Unisearch Limited, Commonwealth Scientific and Industrial ResearchInventors: David H.

Patent number: T105202Abstract: Disclosed is the preparation of water-dissipatable polyesters and polyesteramides wherein at least a part of one of the monomeric components from which it is derived is a polycarboxylic acid or polyhydric alcohol which contains a sulfonic acid salt moiety derived from a nitrogen-containing base having an ionization constant in water at 25.degree. C. of 10.sup.-3 to 10.sup.-10. Also disclosed is the use of such polymers as sizes for fibers of glass, ceramics, etc., where the size is removed by burning and little or no ash residue is important.Type: GrantFiled: July 20, 1984Date of Patent: March 5, 1985Inventor: Kenneth R.
