    摘要: Sorbents used for drying organic liquid process streams can be regenerated by passing an organic liquid carrier solvent such as n-octanol therethrough at a temperature sufficient to dissolve water trapped in the sorbent, thus regenerating it, and subsequently cooling the organic liquid carrier solvent/water solution such that it separates out allowing recycle of the organic liquid. This method of sorbent regeneration allows the use of low grade heat for regeneration thus improving the viability of sorbent drying plant.

    摘要: Catalysts of the ZSM-5 synthetic zeolite type can be prepared by heating a mixture of a precursor for an alumina hydrate, a precursor for silica hydrogel, an alkali metal hydroxide and water together with an organic templating agent selected from the group of carboxymethylcellulose, the condensation product of an alkanolamine and a fatty acid and cellulose hydroxyethyl ether and therafter heating the reaction product under autogeneous conditions. Unlike prior proposals ZSM-5 which is uncontaminated by other zeolites, is prepared in high yield.

    摘要: A mineral mining machine having a rotary cutter and a probe on the cutter head which senses the cutting horizon of the cutter head relative to boundaries of the mineral seam and which derives an electric signal which is fed to control means on the body of the machine for controlling the machine''s steering mechanism. The signal is conveyed from the rotating cutter to the non-rotating body via two spaced annular plates arranged as a capacitor.

    摘要: The invention relates to apparatus for steering longwall mining machines. The apparatus comprises an electromagnetic-radiation emitter/detector which is mounted on the end of an arm pivotally mounted on the machine. The emitter/detector is located immediately behind the machine''s rotary cutter and is urged by a hydraulic jack so as to remain close to the roof.
