IPC: B28C5/12
Filed: 1950-05-10
Abstract: 668,993. Mixing appliances. AUGUST, P. May 10, 1950, No. 11640/50. Class 86 A concrete mixer comprises a horizontally inclined semi-circular trough containing a mixing screw, and a conveyer screw for continuously feeding the material to be mixed to the lower end of said mixing screw whence, while being mixed, it is conveyed by the mixing screw to the upper end of the mixing trough, the mixing screw comprising a helical, internally-open peripherally circular mixing blade of periodically changing width carried by spokes and having angular spaced slots formed at its outer edge, and the mixing trough being charged by the feed conveyer screws to less than one half of its capacity. As described a trough 1, Fig. 1, of semi-circular cross section mounted upon an undercarriage 8 is adapted to be supported in an inclined position by a folding strut 9. A longitudinal shaft 5 supports the mixing screw 2 in the trough an dalso carries a feeding screw 4 within a preliminary mixing chamber 3 situated beneath material hoppers 10, 11. The feeding screw 4 is formed with a blade of progressively increasing depth so that it can receive materials from each of the hoppers 10, 11 in proportions depending upon the position of an adjustable shutter 13. The feeding screw 4 maintains the level of the materials in the mixing trough approximately at the line a-b, Fig. 2. The mixing screw 2 is of helical strip form the central opening being elliptical and the periphery being cut away as at 18 to allow some of the material to fall back as the zones of the helical strip having threduced radial width pass through the materials. The helical strip may be formed of separate but overlapping helical sections Fig. 3, (not shown). A hopper 12 with a rotating feeder device carried by a shaft 14 may be provided to discharge directly into the trough 1. Rotating feeder devices may also be carried by the shaft 14 within hoppers 1C, 11. Water may be introduced by a spray 19 which is adjustable in position longitudinally of the trough.

Abstract: 963,291. Supplying electricity to furnaces. Y. ASAKAWA. March 30, 1961 [March 31, 1960; July 25, 1960], No. 11825/61. Heading F4B. [Also in Division F1] In a method of improving the efficiency of fuel combustion, a high voltage electric potential is applied to one or more electrodes to create an ionizing field within the combustion zone. A voltage is applied to the electrode 13, connected to the secondary coil 11a of a transformer, the electrode being arranged in the flame of liquid fuel 14. The flame is positively or negatively ionized to assist mixing with air. A direct current may be applied to the electrode. A whirl current of air produced by the A.C. electric or magnetic field of poles 17 and 18 also assists mixing. In another embodiment a further electrode may be arranged in the flue of a furnace which may be supplied with secondary air so that the high temperature exhaust gases are used for heating the charging air or water and so that the emission of smoke is subdued. The method may be used with fuels such as finely ground coal, heavy oil, fibre from pressed blocks impregnated with alcohol or liquid alcohol and in furnaces such as a blast furnace, iron cupola, flat furnace, tempering furnace, ore-roasting furnace, rotary furnace, air pre-heating furnaces or in I.C. engines or gas turbines (see Division F1).

Title: Process of recovering uranium values
IPC: C01G43/06
Filed: 1957-04-16
Abstract: Uranium is recovered as uranium hexafluoride from uranium-containing metallic materials, for example, spent atomic reactor fuel slugs, by reacting the material with an alkali-metal acid fluoride, especially potassium hydrogen fluoride, at above room temperature, treating the resulting mixture with hydrogen fluoride between 60 DEG  C. and 250 DEG  C., finally treating with fluorine at a temperature up to 700 DEG  C., and recovering the volatile hexafluoride formed.  If desired, the material may be treated with hydrogen at from 150 DEG C. to 250 DEG  C. to form a hydride, either prior to or concurrently with the step of reacting with alkali-metal acid fluoride.  The are preferably between 4 and 12 mols. of the acid fluoride for each mol. of the material.  It is advantageous to employ more than the stoichiometric amount of hydrogen fluoride required to react with the material.  An example refers to the separation of uranium from a mixture with thorium.

The needle 5 is inclined towards the operator so that movement of the looper in a vertical plane causes relative movement from side to side of the needle. As shown the looper has an eye to carry its own thread but a looper can be provided without its own thread which only takes the needle thread. A conventional eyed looper 7 is also provided to produce a double loop seam adjacent the overedge seam by co-operating with a second needle 5 (Fig. 1). The looper 7 is oscillated from the auxiliary shaft and given a needle avoiding motion from an eccentric on the main shaft which causes endwise movement of the shaft 37.
