Title: Improvements in or relating to means for catching fish by electricity
IPC: A01K79/02
Filed: 1950-08-10
Abstract: 693,229. Condenser arrangements. SIEMENS - SCHUCKERTWERKE AKT. - GES. Aug. 10, 1950 [Aug. 10, 1949; Sept. 3, 1949; Feb. 18, 1950; March 8, 1950; March 28, 1950; March 28, 1950], No. 19965/50. Class 38 (iv). [Also in Groups VI and XL (c)] In an arrangement for catching fish by means of D.C. impulses transmitted through the water between electrodes 5, 6, a condenser 1 is connected through a choke 4 to a D.C. charging source 12 and a mechanical high-speed switch 15 or an ignitron connects the condenser to the electrodes when the voltage on the condenser is a maximum above the D.C. charging voltage and disconnects the condenser from the electrodes when the discharge current passes through zero. The mechanical switch 15 is closed by utilizing the momentary voltage developed on a winding 19 on a switch coil 18 in the charging circuit when the oscillatory charging current passes through zero and the . opening of the switch is effected by utilizing the voltage on a winding on a second switch coil 17 in the discharge circuit when the oscillatory discharge current passes through zero. The second switch coil 17 delays both the rise and fall of the discharge current and prevents arcing at the switch contacts. A dry rectifier may be substituted for or inserted in series with the second switch coil 17 and the reverse voltage developed on the rectifier when the discharge current passes through zero may be used to open the switch. The switch may be actuated by cam-controlled means or by electric timing circuits. Each switch coil 17, 18 consists of a single conductor around which a thin ribbon of nickel-iron alloy is wound and each is saturated by the current passing through it except when the current is nearly zero. The magnetic characteristic of the switch coils is rectangular. When an ignitron is used instead of the mechanical switch it is ignited by utilizing the reversal of voltage on a resistance inserted into the charging circuit or by utilizing the voltage developed on a resistance connected by a rectifier to a resistance in the charging circuit. When the D.C. charging source consists of an A.C. generator and a rectifier the reverse voltage developed on the rectifier by the oscillatory charging current may be utilized to ignite the ignitron. In order to vary the voltage, duration and frequency of the discharge impulses the choke 4 and the condenser 1 are sub-divided into groups of elements which can be connected in series and/or parallel and the D.C. supply voltage is varied by means of a regulating resistance in the shunt winding of the D.C. generator. The current impulses may be arranged in groups separated by relatively long intervals without any impulse.

Title: Improvements relating to hydrous oxide sols
Inventor: FITCH FREDERICK TROUPE
IPC: B01J13/00
Filed: 1960-06-09
Abstract: Hydrothermally stable hydrous thoria-urania sols suitable for use as a single-phase fuel in a nuclear reactor comprise negatively charged particles consisting of thoria and urania coated with silica and dispersed in an electrolyte-free aqueous medium; they are prepared by mixing a thoria-urania sol with a sufficient quantity of freshly prepared silica sol to change the charge on the particles from positive to negative.  The aqueous medium may be heavy water.  The initial thoria-urania sol, which preferably has a micelle size greater than 25 millimicrons, may be prepared by gradually removing anions from dilute solutions of thorium and uranium salts at elevated temperature, e.g. by electrodialysis or dialysis with an anion-permeable membrane, ion exchange, decomposition of a salt of a volatile acid or electrolysis of a mixed salt solution, the anions of said salts being oxidized to a volatile state.  Nitrates, chlorides and perchlorates are the preferred starting materials, salts of polybasic anions being unsuitable.  The initial silica sol may be prepared by passing sodium silicate through a catio exchange resin, and preferred sols have a micelle size than 5 milliomicrons.  The addition of the silica sol is made rapidly and with thorough mixing to avoid precipitation at the isoelectric point.  The mixed sol is preferably stabilized by raising the pH to 7,0 - 11,0 by adding an alkali metal hydroxide or other base not containing an element of high thermal neutron cross-section.  Details are provided of preferred ratios of thoria-urania to silica and concentrations at all stages.  In the example, the thoria-urania sol was prepared by circulating a thorium nitrate/uranyl nitrate solution from a tank at 98 DEG  - 99 DEG C. through a cooler (where the temperature was reduced to 25 - 30 DEG C.) and a pump to an electrodialysis cell (see Group XXXVI), thence to a preheater to raise the temperature to 70 DEG  - 90 DEG C., and back to the tank.  An orange sol having a pH of 4,0 was produced.  To this silica sol was added, and the pH raised to 9 with NaOH.  The sol was refluxed (e.g. at 150 DEG C. or above) and deionized by passage through a mixed resin to reduce the anion content.  The pH was restored to 8:35 with NaOH.  The sol was concentrated partly to 18,6% solids and partly to 41% solids and each portion was stable at 250 DEG C. under the pressure generated in a sealed container.  Specification 905,920 is referred to.

Abstract: 622,729. Embossing. DETREZ, R. Aug. 10, 1945, No. 20525. Convention date, July 7, 1944. [Class 100 (ii)] [Also in Groups XVII and XXIX] Hydraulic movement in a machine for performing reciprocatory operations on articles supported thereby (e.g. impressing articles by means of a die, or capping or corking bottles) is locked during the said operation by a sealing means temporarily interposed in the passage of liquid between an actuated piston of the hydraulic system on the one hand and the source of pressure on the other. The invention is shown applied to a bottlecorking machine in which a bottle is raised to the corking position by hydraulic piston 3 attached to bottle rest 2. Supply of pressure liquid to the piston through pipe 5 is then cut off during the corking operation by a sealing piston 9 reciprocated by a cam 11. Liquid trapped in the lower part of cylinder 4 prevents the bottle from yielding during the descent of corking plunger 8. In another embodiment, the bottle rest is fixed and the corking head is lowered hydraulically; during the corking operation, two cam-operated valves simultaneously seal the pipes leading to both sides of the hydraulic piston locking the corking head against either up or down movement.
