Abstract: 1359064 Diverting articles from roller conveyers STOHR-FORDERANLAGEN SALZER GmbH 26 May 1972 [28 May 1971] 24962/72 Heading B8A Articles are diverted from a main roller conveyer 1, if desired, to a branch conveyer 2, by the action of a subsidiary belt or roller conveyer device 8. The latter tilts about an axis parallel with the conveyer 2, from a position beneath, to a position at least partly above, the operative surface of the conveyer 1. As shown, the device 8 is a belt conveyer which is mounted on an L- shaped frame (Fig. 5, not shown) as viewed in side elevation.

Title: Photographic camera shutter
IPC: G03B9/70
Filed: 1961-07-10
Abstract: 910,987. Camera shutters. AGFA A.G. July 10, 1961 [July 16, 1960 (2)], No. 24986/61. Class 98 (1). A photographic camera with pivoted shutter blades comprises two blade rings relatively rotatable in the same direction to open and close the blades and to close and open a flashlight circuit. As shown in Fig. 3 the blades 204 are opened and closed by rings 202, 203 respectively. An electrical contact 217 is mounted on the ring 202 so that when it runs down it engages a spring contact 216 and closes the flashlight circuit. When ring 203 moves to close the blades a projection 218 engages and moves contact 216 away from contact 218 and breaks the circuit. In another embodiment the movable spring contact is on the blade opening ring and in another embodiment the contacts are both spring type, neither is on a blade ring, and projections on the two rings move the contacts together and apart. In the embodiment of Fig. 4, the two contacts 310, 303 are controlled by a lever 307 on which contact 310 is mounted. The lever is pivoted to close the flash circuit when it moves over cam surface 305b of the blade opening ring 305 and pivots to close it when it moves to cam 306c on the closing ring 306. In all the above embodiments the blade rings are set by simultaneous rotation and therefore this movement has no effect on the flash circuit.

Froth flotation apparatus operating under a common head of vacuum comprises a pre-conditioning and aerating unit 1, into which pulp and gas are introduced via pipes 3, 4, the pulp being fed via a pipe 6 into a flotation chamber 8. Additional gas is introduced via a pipe 13. Froth is collected by a section 10 and directed into a bubble column 19. Preconditioned particles, treated with reagents to be floatable proceed upwards, and unwanted particles downwards, the downward movement being assisted by wash solutions introduced at 21. Final concentrate is drawn into a cyclone 23 for separation of solids and liquids, and concentrate pulp is discharged into a vessel 25 and over a weir 16, vessel 17 and weir 18. Gas separated in the cyclone is directed via a conduit 27 to a vacuum pump. In a further embodiment, five flotation chambers are employed operating under a common head of vacuum. Pulp material is drawn into rough flotation units (28, 29 Fig. 2) and the rough concentrates rise in columns (37, 38) and are combined in a chamber (30), separation of gas being effected in cyclones (41, 42.) Tailing pulp from the chamber (30) is returned to the chamber (28). Further flotation scavenger chambers (31, 32) receive the rougher tailings for further separation and the coarsest tailings are discharged at (53, 54).

Petroleum fractions are separated by liquidliquid extraction at 20-150‹ C. with 1 to 4 parts by weight of a solvent composed of 70 to 99 wt. per cent acetone and 30 to 1 wt. per cent water. The acetone can be recovered from the raffinate and extract phases by washing with water or by distillation. The extraction can be used to remove aromatics from jet fuels or kerosenes. Distillates from naphthenic crude oil are extracted and the raffinates treated with concentrated H 2 SO 4  and active clay to provide electrical insulating oil or base oils for diesel engine lubricants. The extracts and raffinates can be treated by hydrofining instead of with acid and clay.

Title: Improvements in screw propeller blades
IPC: B64C11/18
Filed: 1919-10-14
Abstract: 158,029. Anspach, P. A. L. Oct. 14, 1919. Screw - propeller blades, more particularly for aeroplanes, are made of special cross-section to facilitate their movement through the fluid. The curve ab of the blade section constitutes the main impact surface and is made slightly convex. The leading edge of the blade is formed of a curve fg of small angle of incidence and a curve ag of large angle of incidence. The air displaced by the surface ab reacts on the surface bcd, which is at first slightly convex, and then concave towards the edge d of the blade. A convex curve fe is provided at the rear face of the leading edge, followed by a curve ed, which is mainly convex but has a slightly concave portion adjacent to the edge d. The blade near the axis of rotation is practically symmetrical on both sides, but becomes less symmetrical and thinner towards the tip. The part cd of the impact surface is tangential at d to the general direction of motion of the section.

Title: Precipitation of zirconium and fluoride ions from solutions
IPC: G21C19/46
Filed: 1962-07-02
Abstract: Zirconium and fluoride ions are removed from a solution containing hexavalent uranium, zirconium and hydrofluoric acid, by adding an aqueous solution containing at least two mols. of sodium formate for each mol. of zirconium to the said solution whereby the zirconium and fluoride ions are precipitated while uranium remains in solution, and separating the precipitate from the solution.  The formate solution may have a concentration of between 3 and 8 M.  The precipitation may be carried out at between 20 DEG  and 60 DEG  C., and the precipitate may be washed with an aqueous solution containing sodium nitrate. The present process is particularly applicable to the treatment of uranium-zirconium alloy fuel elements which are dissolved in a hydrofluoric acid dissolver solution, the uranium being oxidized to the hexavalent state, i.e. with hydrogen peroxide or chromic acid, and the zirconium and fluoride ions being removed as above.

Title: Process for nitration of hydrocarbons
IPC: C07C201/08
Filed: 1965-06-17
Abstract: Nitrohydrocarbons are prepared by reacting 60-100% by wt nitric acid with a molar excess C1- 10 hydrocarbon which is an alkane, cycloalkane or benzene in the vapour phase under superatmospheric pressure at 300-700 DEG  C. for a time sufficient to ntrate the hydrocarbon and no longer than 50 milliseconds and immediately quenching the reaction products, to freeze the equilibrium of the reaction, by rapid expansion.  The preferred hydrocarbon is methane. The reaction products are preferably expanded to approximately atmospheric pressure into a water-cooled chamber. The reaction is conveniently effected in a rocket engine.  Examples relate to the nitration of methane, decane, cyclohexane, pentane and benzene.  The process is illustrated by reference to drawings (not shown).
