Abstract: In an adjustable chuck for gripping workpieces of different sizes, three jaws are mounted for relative movement. A hydraulically driven mechanism is operable selectively for closing the jaws to grip a workpiece and for opening the jaws to free the workpiece. Two strain gauges on one of the jaws sense the gripping force applied by the jaws to the workpiece. A computer, which responds to the strain gauges, coacts with a control relay and with hydraulic valves to control flow of hydraulic fluid into and from the closing and opening mechanism. A system comprising a plurality of such chucks is contemplated, in which one computer coacts therewith to control the closing and opening mechanism of any selected chuck of the system, and which adjusts itself for minor variations among the system chucks.

Abstract: The invention relates to a feed and to a process for its production. According to the process, a fatty substance is converted to the form of a metal salt of a fatty acid or fatty acids, and is combined with a carrier such as a concentrated feed. In the salt form the salt is protected in such a way that it will not disturb the disintegration taking place in the rumen of a ruminant, but it is, nevertheless, exploitable by the digestive system of the animal. What is essential in the invention is that the metal salt is formed into a three-dimensional matrix so that a substantially liquid fat or fatty acids remain in the cavities of the matrix. In a matrix form such as this the fat is fluid, and it can be transferred and batched like a liquid. It is possible to use vegetable oils which contain unsaturated fats and fatty acids for the production of a feed, whereby the fats and fatty acids can be caused, by means of the protection, to pass through the digestive system of a ruminant to the milk produced.

Abstract: An apparatus transfers heat for the purpose of purifying raw feed liquid, separating dissolved gases from liquids, vaporizing heat transfer fluids or containing and regulating biological/chemical reactions. The feed liquid is directed into an evaporator module submerged in a solar pond or other body of heated liquid. The evaporator module includes a rotating housing through which a plurality of spaced apart substantially horizontal open ended heat transfer tubes extend. A heating liquid is directed through the heat transfer tubes. The feedwater is distributed within the evaporator module so as to cause the feedwater to descend into heat transferring contact with the heat transfer tubes and thereby vaporize a portion of the feedwater. A preferred embodiment of the evaporator module is disclosed which includes cavitation fins for urging the heated liquid through the evaporator module.
