Abstract: Abstract of the Disclosure Toroidal motor/pump comprising a toroidal cylindrical casing with a disc rotor containing rotatably mounted vanes which are able to seal off the cylinder, wherein, on the shaft of the vanes, rockers are fixed which during rotation of the motor/pump cooperate with a curved disc, which casing possesses a restricted section in the shape of the disc rotor through which the vanes in closed position are able to pass, as well as an inlet and outlet port for a pressure medium in the section wherein the vanes are rotating.  To guarantee smooth working between the casing halves and the disc rotor two complementary twin axially curved discs are arranged between which the rockers run, the rockers having the general shape of a central cam with two side cams so that they are able to move through the disc rotor.  The restriction is so con-structed that the vane in its passing position is not turned a complete 90°, but about 85°.

Abstract: Abstract A novel rotor is provided for attachment to the lower end portion of the motor-driven shaft of a liquid-mixing device, such as a liquifier or mixer commonly used in the preparation of milkshakes, malts and like ice cream mixes.  The rotor features a one-piece ele-ment in the form of a V having a flat bottom and a pair of upwardly and outwardly divergent arms providing mix-ing blades related in diametrically opposed fashion.  A disk having a central opening receives the shaft and is disposed in radial plane spaced axially above the flat bottom and its periphery is affixed to the terminal upper ends of the blade arms.  The disk has an annular flange which presents a smooth circular surface that prevents the blades from damaging the mix container during opera-tion of the mixer as well as during removal of the con-tainer while the shaft and rotor are still rotating.

Abstract: ABSTRACT OF THE DISCLOSURE:           A process is described in which a TiO2 concentrate is recovered from TiO2-containing starting materials, where-in said starting materials are leached with dilute mineral acid at an elevated temperature and the separated residue is treated with reducing agents and is subsequently leached with dilute mineral acid at an elevated temperature. In order to produce a high-grade TiO2 concentrate with the aid of dilute waste sulfuric acid, which constitutes a waste pro-duct and is discarded in the process, a) the starting material is leached in the first leaching stage with dilute waste sul-furic acid at a temperature of 160 to 180°C and under super-atmospheric pressure to produce an intermediate concentrate having a TiO2 content of about 60% or more, b) the intermediate concentrate is filtered off and is reduced by a treatment with a carbon-containing fuel after an optional oxidation, c) the dilute waste sulfuric acid obtained as a filtrate from the first leaching stage is used to leach the reduced product of step b) at temperatures between 60 and 180°C and, if desired, under superatmospheric pressure so as to consume all free sulfuric acid and to obtain a concentrate having a TiO2 content of 80% or more, and d) iron sulfate heptahydrate is crystallized in the filtrate.

Abstract: DEMAND RESPONSIVE FLOW REGULATOR VALVE            Abstract of the Disclosure A demand responsive flow regulator valve for use with a power steering pump and steering mechanism has a valve spool slidably disposed in a housing and responsive to a pressure differential across an orifice for the purpose of bypassing excess pump flow.  The flow control orifice establishes pressure signals proportional to pump flow to the steering mechanism.          The pressure signals are operative on the valve spool to control the bypassing of excess pump flow.  A spring loaded metering rod disposed in the flow control orifice increases the effective area of the orifice when pressure demand at the steering mechanism increases thereby increasing the fluid flow to the steering mechanism while simultaneously decreasing the bypass flow.

Then, the interior of the refining ladle is held in an inert gas atmosphere.  A reducing agent such as an A? reducing agent is charged into the molten steel.  Electrodes are dipped in slag on the molten steel to form an arc therebetween so as to heat the molten steel with an arc.  The ore is reduced by the reducing agent, so that a metallic component of the ore is added to the molten steel.  On the other hand, carbon electrodes each having a gas supply port at its lower end can be used to inject an ore powder or particles from the injection ports to the arc between the electrodes and molten steel.  The ore is reduced by electrode carbon with arc heat, so that a desired component is added to the molten steel.
