Abstract: A sampling device comprising an outer tube and an inner tube that is eccentrically mounted for rotation within the outer tube, the inner and outer tubes being disposed in spaced, parallel relationship so that relative rotation therebetween cuts a sample of bulk material and retains that sample for subsequent removal.

Abstract: Method for the production of a catalyst suitable for use in the synthesis of methanol obtained by reacting carbon monoxide, carbon dioxide or mixtures thereof, with hydrogen, comprising forming an alloy containing 0 to 50 weight percent zinc, 30 to 75 weight percent aluminum and the balance being substantially all copper, and extracting aluminum from the alloy using an effective concentration of zincate ions in an aqueous solution of an alkali metal hydroxide. Catalysts made by this method are disclosed, together with their use in the preparation of methanol.

Abstract: A traction power supply system in which one, two or three single-phase traction loads are supplied from a 3-phase high voltage system. Balancing of the load in each phase of the high voltage system and reduction of reactive currents in that high voltage system is achieved by simulating any further single-phase load or loads necessary to make the number up to three and providing individual controllable balancing circuits for all of the single phase circuits together with individual harmonic filters designed to include accommodation of the harmonic currents generated by the balancing circuits.

Abstract: A container/dispenser is described for carrying and dispensing heavy electrical cable of the plastic or rubber-coated variety that is used in wiring homes and businesses. The container has unitary construction and is fabricated from a strong but flexible material, such as nylon, sailcloth, etc. A closeable opening is provided in one end for the insertion of a coil of electrical cable, and a central exit opening is provided for extruding cable from the center of the coil. A detachable and adjustable strap is included for carrying the container/dispenser. In operation, a preformed coil of electrical cable is inserted through the opening into the container/dispenser and is strand-wise extruded from the central exit opening. The opening through which the coil is placed in the container/dispenser can be closed, by means such as velcro fasteners.

Abstract: A test element is provided which can detect and measure extremely low concentrations of formaldehyde in the environment. The test strip comprises a support having thereon a formaldehyde-sensitive layer comprising an inert formaldehyde-permeable binder which stabilizes sulphite ions against aerial oxidation having dispersed therein pararosaniline or an acid derivative thereof and sulphite ions. The test element requires no processing and can be fixed to obtain a permanent record.

Abstract: A water-insoluble organic photographic addendum is recovered from a dispersion of a mixture thereof and an oil-former in an aqueous medium containing a hydrophilic colloid and a surface active agent by adding a selected oleophilic non-ionic surface active agent.
