Abstract: ABSTRACT           A class of controllers is disclosed for electric motors of an open-circuit-armature-windings type in which energy recovery from interrupted armature windings improves operation and efficiency.  Such motors have at least one repeatable section and comprise a stator and an armature mounted for relative movement.  The stator has, for each repeatable section, two stator magnetic poles inductively linked by at least one stator winding or energized by permanent magnets.          The armature has a magnetic structure and, for each repeatable section, multiple open circuit windings displaced from each other in the direction of relative movement and inductively linking the structure.  The motor and controller provide for simultaneously establishing individual electrical connections to from none to at least one of the armature windings, and, when stator windings are used, to from none to all of the stator windings.  Control of the electrical connections to the armature windings allows varying the number and strength levels as avail-able of the armature electromagnetic poles, and, levels stator windings are used, allows varying the number and strength levels as available of the energized stator magnetic poles; no more than two armature electromagnetic poles are formed per repeat-able section.  The controller can vary the orientation of armature poles with respect to the stator poles for maximum effectiveness and reversing direction of the generation of force and torque.  The controllers also cooperatively control the electrical connections and the orientations to thereby control both the magnitude and direction of force and torque generated by the motor.  These controllers apply to all sizes of such motors and are expected to increase all motor applications.

Abstract: REFERENCE VOLTAGE GENERATOR DEVICE            Abstract of the Disclosure The method is for manufacturing a semiconductor device with at least a pair of insulated gate field-effect transistors having semiconductor gate electrodes of different conductivity types.  A semiconductor layer of one conductivity type is selectively removed to provide patterns of first and second gate electrodes, and a mask is formed over the first gate electrode except for the second gate electrode.          Thereafter, an impurity of the opposite conductivity type is introduced into the surface of a semiconductor substrate, over which the first and second gate electrodes are formed, to form source and drain semiconductor regions on opposite sides of each of the first and second gate electrodes and to convert the conductivity type of the unmasked second gate electrode to the opposite conductivity type.  The method has the advantage of enabling manufacture of an improved semi-conductor device without increasing the number of fabrication steps.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of processing cattle feed products based on agricultural material, such as sugar best pulp, citrus fruit pulp and peel, and material obtained in the fermentation of agricultural material, such as distiller's grain, which material is available after either a fermentation process or sugar leaching of beet pulp or after mechanical dewatering (pressing) or evaporation.        To improve the nutrient value and general quality of the cattle feed product while at the same time improving the heat economy of the production process the invention proposes a method comprising the steps of preheating the material in steam, known as carrier steam, disintegrating the material in said steam for fragmentation thereof into uniform particle size, and drying the material particles in heat exchangers. Preferably the carrier steam is a part of the drying medium used in the process, that is for heating and conveyance of the particles.          The cattle feed processing steps may be performed in the order indicated or processed in any other suitable order.  The cattle feed product/material is then seperated from the carrier steam and cooled.        The plant designed to perform the method includes a pressure vessel to which moist cattle-feed material is transported via a pressure lock, equipment for disintegration of the material to equalize the paritcle size, equiptment for drying the maaterial and a pressure lock to discharge and separate the material from the carrier steam.

Abstract: PROCESS FOR RECOVERING URANIUM USING AN ALKYL PYROPHOSPHORIC ACID   AND ALKALINE STRIPPING SOLUTION                    Abstract A process is described for the recovery of uranium from wet-process phosphoric acid utilizing an alkyl pyrophosphoric acid extractant.  The extractant also contains a modifier for retaining the alkyl pvrophosphoric acid ester in solution in an essentially water-immiscible organic diluent during stripping. After extracting the uranium from wet-process acid, the APPA extractant is treated with an oxidizing agent such as hydrogen peroxide and the uranium stripped into an alkaline stripping solution.  The alkaline stripping solution is an aqueous solution of an alkali metal or ammonium carbonate or hydroxide. The barren extractant is recycled for contacting with fresh wet-process acid.  Any ferric iron present is precipitated in the stripping solution and then separated from the solution.  The uranium is recovered, dried and calcined to a U308 product.
