Title: Improvements in the process for the manufacture of aluminous cement in rotary furnaces
IPC: C04B7/32
Filed: 1924-02-14
Abstract: 211,497. DÚcolland, R. Feb. 14, 1923, [Convention date]. Drawings to Specification. Rotary furnaces.-Aluminous cements are made in ordinary rotary kilns by (a) lengthening the zone, and (b) preventing the formation of a coating due to the fusing of the fuel ashes. The lengthening of the heating zone is accomplished by employing as a fuel a coal such as lignite which contains a large proportion of volatile neutral products, or by diluting the roasting atmosphere with water-vapour or other neutral gas, e.g. waste furnace gases delivered from the foot of the chimney to the air inlet. The prevention of the formation of a coating of fused ashes is effected by mixing with the fuel a sufficient proportion of limestone to combine with the silica, iron, &c., and render the ash refractory, or by removing the refractory lining of the kiln at the point of formation of the fused ash, and cooling the plating by external means.

Title: Improved method for reprocessing aluminum-containing spent nuclear fuels
IPC: C01G43/06
Filed: 1965-01-29
Abstract: Uranium hexafluoride is recovered from spent aluminium-containing nuclear fuel by dissolving the fuel at a temperature not above 600 DEG  C. in a molten salt solvent of substantially 67 KF-21ZrF4-12 AlF3 mol. per cent while passing anhydrous HF through the melt, and when the AlF3 content reaches 32 mol. per cent, removing the uranium as volatile UF6 by passing fluorine gas through the melt at about 600 DEG  C.  A portion of the melt is discarded and the mol. per cent composition is restored to its original value by adding KF and 2KF.ZrF4 salts.  The process may then be repeated. UF6 vapour may be cooled to 100 DEG  C., adsorbed on a bed of NaF, and further purified from fission products by heating the bed to 400 DEG  C. and condensing volatilized UF6.

Abstract: 1525601 Headlamp tilting systems LUCAS ELECTRICAL Ltd 6 Jan 1976 [31 Jan 1975] 4215/75 Heading F4R  In a hydro-mechanical system for controlling the inclination of the headlamps of a motor vehicle in a vertical plane in accordance with the attitude of the vehicle body, a movement modifier 11 has a fluid medium 19 which locks an output member 21 relative to an input member 14 when the latter is subjected to a sudden movement by a sensor 10 connected with an unsuspended vehicle body part, e.g. when the vehicle accelerates. This movement is carried through a transmission arrangement 12 to tilt the headlamps H. Such sudden movement overrides an equilibrium established between biasing springs 17, 42 in the movement modifier 11 and the transmission system. The fluid medium 9 is a grease applied between the output member 21 and a sleeve 16 connected via a housing 13 to the input member 14 which allows slow restoration of an equilibrium between the springs 17, 42. Thus, if the load on the vehicle increases, sensor 10 moves to the right and the initial upward tilting of the headlamps H is reduced as the grease 19 allows the input member 21 to move to re-establish equilibrium between the springs 17, 42. Headlamp flutter caused by wheel bounce is prevented by a damper unit 36.

Abstract: 1,029,772. Magnetic storage. E. TEBBENHOFF. Feb. 4, 1963 [Feb. 5, 1962], No. 4429/63. Heading H3B. [Also in Division H1] An electric circuit network comprises a fabric woven with bare metallic conductors a separated by dielectric threads c, as the warp components, and bare metallic conductors b separated by dielectric threads c, as the weft components; the dielectric threads also isolate the warp metallic conductors from the weft metallic conductors except at predetermined junctions (indicated by circles in Fig. 1). The warp conductors may be sub-divided into sections each associated with an electric subassembly or circuit component such as a transfluxor, the fabric being cut to form recesses (Fig. 5, not shown). The weft and warp wires may have part of their length constituted by a resistance wire and the warp wires may comprise conductive or non-conductive material on which are mounted small ferrite cores about which the weft wires are woven. Also the warp wires may comprise ferrite core rolls wound with insulated conductive wire in the same manner as the bass string of a musical instrument is wound or they may be made from magnetic material. The circuit network may be a simple woven fabric (Fig. 3, not shown) and the circuit interconnections may be effected in the already woven fabric by soldering, stitching with conductive wires or weld-pressing. When the junctions between warp and weft wires are made after the fabric has been woven, by " dip soldering " it is desirable that the dielectric threads c comprise glass fibre yarns since this is not sensitive to soldering temperatures. To connect a warp wire to one or more other warp wires small preformed elements of ferrite or paramagnetic material may be placed into the woven fabric. Also the rear surface of the fabric may be insulated and reinforced by dipping the fabric into synthetic resin.
