Abstract: ABSTRACT OF THE DISCLOSURE         A method of controlling a heat transfer plant having a circulating heat carrier which circulates at a constant rate. By the control method central heating plants can enjoy optimum running as a function of the heat consumed and the problems of the prior art in over-heating or under-heating rooms are avoided. In the method the feed temperature is so regulated as a function of the temperature differential measured between feed and return, that the actual temperature differential is equal to an adjustable desired temperature differential or a desired temperature differential pattern, and in such a way that the lower limit of the feed temperature is limited by a predetermined minimum temperature.

Abstract: MULTIPLE PLANE SPOKE STRUCTURE FOR A SUPERCONDUCTING DYNAMOELECTRIC MACHINE     ABSTRACT OF THE DISCLOSURE         A multiple plane spoke structure for supporting a superconducting rotor assembly of a dynamoelectric machine.          A plurality of generally radially extending support spokes interconnect an ambient temperature rotor portion with a cryogenic temperature rotor portion.  The spokes are secured in tension between the two rotor portions and are displaced one from another along the axial length of the rotor member.          The spokes are preferably grouped together in sets of at least two each with at least one of the spokes being angu-larly displaced with respect to the remaining spokes.  The proper placement of these groups of spokes is determined by comparing the maximum deflection of the rotor assembly at the operational frequency to the maximum allowable deflec-tion which can be tolerated under steady state conditions.          Each spoke projects through radial openings in the core of the field winding structure.  These openings are preferably located in the pole portions of the rotor core structure which lie intermediate of next adjacent field winding groups.

Abstract: ABSTRACT OF THE DISCLOSURE         Improved efficiencies in mill operations can be achieved in tumbling mill, wet grinding of coal or ore containing metal values by carrying out the grinding process in the presence of a chemical grinding aid.  An increase in the rate of ore-particle breakage obtained by use of the grinding aid allows higher ore-slurry densities to be ground without an accompanying decrease in grinding kinetics.  This permits either a greater throughput of ground slurry per unit of time and therefor a lower energy consumption per ton of ore ground and/or an increase in the fineness of ground slurry at a constant throughput.

Abstract: ABSTRACT      A vehicle, such as a self-dumping dirt truck or a trailer, is equipped with a powered assembly of components to automatically clean debris from roadside ditches or irrigation ditches, preferably powered by the truck engine, a tractor engine, or an auxiliary engine, which in turn drives a hydraulic pump of a hydraulic system powering several hydraulic motors.  The debris, dirt, gravel and weeds, are loosened and collected from the ditches along-side a road and then conveyed to a dirt-collecting chamber of the trailer or truck.  At times if the debris is not objectionable, it may be discharged back. near the roadbank but removed from the ditch area.  This powered assembly of components comprises:  a leading powered auger for rotary and advancing movement in a ditch; a powered cleaner conveyor selectively positioned and operating just behind the auger, which it supports, to convey collected debris up and out of the ditch; a powered bucket elevator to continue conveying the collected debris to a higher elevation on the trailer or truck; a powered belt conveyor to move the collected debris from the bucket elevator to the dirt-collecting chamber of the trailer or dirt truck, and an interrelated hydraulic drive system using a hydraulic pump and hydraulic motors, powered by the main engine of the dirt truck or tractor, or the auxiliary engine of a trailer.  The powered assembly of the ditch cleaning components is adjustably mounted on the vehicle to be transversely or laterally moved relative to the -i-truck to reach ditches located at different distances from a roadside.  Also for legal highway travel i.e. eight feet wide, these ditch cleaning components are adjustable into such non-use legal width positions.                             -ii-
