Filed: 1926-09-21
Abstract: 260,221. Lanhoffer, I. E., and Lanhoffer, E. O. Oct. 24, 1925, [Convention date]. Pneumatic conveyers.- In apparatus for conveying granular or powdered material through a pipe, the material] is mixed with air under pressure, and the air is permitted to expand at the entrance to the pipe, thereby forcing the material through the pipe and also rendering it mobile. The material is transferred from a hopper S to the conveyer pipe C by a pistontype conveyer A to which compressed air is admitted by a pipe H. The period and time of delivery of compressed air are controlled by an adjustable valve. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following constructions. Material passes from a hopper S,. Fig. 1 (Cancelled), into the compartments of a bladed wheel A which transfers it to the conveyer pipe C. When a compartment reaches the position 5, compressed air from the pipe H is admitted to it through the apertures O. In the form shown in Fig. 3 (Cancelled), the material is transferred from the hopper to the conveyer by a rotor A which is mounted eccentricallv in the stator B and has a series of radially sliding blades K mounted in it. The air, which enters with the material, is compressed during .its transfer to the pipe C. In a modification shutters pivoted on the rotor are adapted to come into contact with the inner face of the stator when the rotor moves past the entrance to the conveyer. These shutters prevent the passage of material into the compartment which has just been emptied. This subject-matter does not appear in the Specification as accepted.

Abstract: 506,123. Discharge apparatus. PATENTVERWERTUNGS-GES. HERMES. Aug. 8, 1938, No. 23404. Convention date, Aug. 7, 1937. [Class 39 (i)] In a gas- or vapour-filled discharge device, primarily for high voltages, having a number of intermediate electrodes 4, 5, &c., arranged between the anode 3 and the cathode 2 for rendering uniform the potential distribution between the anode and the cathode and/or for de-ionizing, the intermediate electrodes, and if necessary, any control electrodes provided such as grids 6, 7 are secured in a tube 32 of quartz or ceramic material which is fitted in the actual discharge vessel 1 and is supported thereby. The object of this arrangement is to avoid damage to the seals due to the heating of the leads when the electrodes are degassed by high frequency heating. The intermediate electrodes and the grids are secured by U- section rings 8 which also serve to prevent discharges in the space between the electrodes and the carrier. The rings are held in the carrier by three screws one of which has a lead wire for the associated electrode. Resilient fmgers are provided to locate the electrodes in the carrier. Each intermediate electrode consists of a number of tubular sections relatively staggered in the axial direction and the central cylinders are closed by partitions 10 to retard the movement of ions. A metal screen 19 surrounding the anode and secured inside the tube has an extension 11 within a groove in the anode to prevent rapidly moving ions from passing to the outside and producing charges on the carrier tube or on the wall of the vessel. The tube is held at its upper end by an annular cap 12 having a tubular part 15 enclosing the base of the upper seal, and the axial position is determined by a resilient ring 16 surrounding the anode lead 17 and insulated by rings 18. Similar means may be employed to prevent axial displacement of the cathode lead. The lower end of the carrier tube is held in a U- section ring 21 having a tubular extension 22 surrounding the base of the lower seal. To prevent discharges along the inner wall of the vessel, thin annular metallic layers 23 are provided in the neighbourhood of the lead-in conductors and preferably conductively connected thereto ; if thicker rings are employed, they should be slotted to avoid heating by induced currents during treatment of the vessel with high frequency current. Metallic caps may also be provided on the leads outside the vessel, and an electrostatic screen 24 surrounds the anode system and may be connected to the anode.

Abstract: 682,425. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. Sept. 26, 1950, No. 23519/50. Class 38 (v) In an earth leakage lockout arrangement for a motor M or other apparatus, a rectified current injected through an earth fault circuit by means of an artificial neutral point impedance U is applied to the D.C. winding of a transductor A to effect the energising of a relay K which opens and remains open to prevent the closing of a contactor C until the fault has been cleared. Thus so long as the fault indicated at 24 persists, a circuit is established from a transformer secondary winding RS<SP>2</SP> and a rectifier E to earth, through earth connection W, the fault, line X, impedance U, auxiliary contacts C4 of the contactor C and the D.C, control winding A4 of the transductor. The A.C. windings A<SP>1</SP> A<SP>2</SP> of the transductor now have minimum impedance and the coil of the relay K is energised from the rectifier F in series with the A.C. windings. The relay contacts K<SP>1</SP> open the remote control protective circuit of Specification 669,133, [Group XI], de-energise a relay H which opens the circuit of the closing coil C<SP>5</SP> of the contactor, the contactor being maintained open so long as the fault remains. Should the fault occur when the motor is in use the contactor is opened by an earth leakage protective circuit which is combined with the lockout arrangement. In Fig. 1 on the occurrence of the fault 24, current flows from the line X through the fault 24, the earth, connection W, resistances T, S, contacts C4 and impedance U to lines Y, Z. The fault current in this circuit establishes a potential across the resistance S, which potential, after rectification by a rectifier G<SP>1</SP>, is applied across a further D.C. control winding A<SP>3</SP> on the transductor. The relay K is energised and opens its contacts K<SP>1</SP> to open the contactor C. the changeover of the contacts C4 to the position shown then render ing the lockout circuit effective. In an alternative arrangement for use where the supply neutral is earthed, the winding A<SP>3</SP> is energised on the occurrence of a fault by a core balance transformer, Fig. 2 (not shown). Specifications 605,927, 623,911, 636,720, 658,823 and 665,576 also are referred to.

Title: Process for the separation of rare earths
IPC: C22B59/00
Filed: 1959-07-10
Abstract: Samarium and/or europium and/or ytterbium are separated in the presence of other rare earths in a process wherein an aqueous solution containing a divalent salt, for example, the chloride, of at least one of the above three elements is treated in a non oxidizing atmosphere, in the presence of an ammonium salt, preferably the chloride, and in the absence of sulphate ions, with ammonia to form an alkaline liquid phase and a solid phase, which solid phase, containing trivalent rare earths, is separated from the liquid phase which contains the samarium, europium, or ytterbium.  The divalent rare earth salts may be prepared by reduction, for example by electrolysis or by sodium vapour.  If it is desired to recover europium free of samarium and ytterbium the reduction may be effected by amalgamated zinc, which only reduces the europium, and the samarium and ytterbium will then be found in the solid phase.  The samarium, europium and ytterbium may be recovered as hydroxides by heating the liquid phase with hydrogen peroxide.  Specification 902,754 is referred to.
