Abstract: A water-dilutable maleinized oil base coating composition is prepared by mixing from about 10 to about 90% by weight water-dilutable maleinized oil with from about 90% to about 10% by weight of a solid particulate polyester which contains from 5 to 35% by weight of a halogen. One of the carboxylic acids used in making the solid particulate polyester contains a halogen. The percentages by weight of the coating composition are based on the total weight of the two components on a solvent free basis. The novel coating composition can be used to advantage for coating any substrate and particularly for coating automobile bodies.

Abstract: An apparatus is operative for processing yarns, filaments or other such elongated elements. An arrangement for controlling the travel of such elongated element includes a device for determining the number of elements breakages occurring per unit time and for generating a corresponding breakage-frequency signal, a device for establishing a reference breakage frequency, and a mechanism for automatically varying the speed of yarn travel as a function of the discrepancy between the reference breakage frequency and the breakage frequency indicated by the breakage-frequency signal.
