Filed: 1918-12-30
Abstract: 135,992. Acton, W. Dec. 30, 1918. Travelling-band filters.-A series of longitudinal suction chambers are formed at the periphery of a rotary drum, the chambers communicating by radial conduits C with passages in the axle leading to a valve I, by means of which some of the chambers are at any time released from suction. An endless band of filtering-material passes round the drum and serves as a conveyer to remove the separated solids, the solids being caused to fall form the band by a braking-roller J, and delivered to a receptacle H. The roller J may be square or grooved. The band is returned to the drum over a spring-controlled roller K. The matter to be filtered is contained in a trough F, and may also be delivered to the drum through an adjustable nozzle G.

Abstract: 517,195. Polymerized compounds. ROHM & HAAS AKT.-GES. July 22, 1938, No. 21822. Convention date, July 22, 1937. [Class 2 (iii)] Symmetrical dichlorethylene is polymerized by employing as polymerization catalyst one or more peroxides, e.g. benzoyl peroxide, hydrogen peroxide or tetrahydronaphthalene peroxide. The reaction may be carried out with heating and under pressure of a gas such as nitrogen, or under the influence of ultra-violet light. The dimeric or polymeric reaction products obtained, in so far as they are of low molecular weight, are liquids having a certain narcotic power and are suitable as high boiling solvents. The products also act as cleansing and softening agents, artificial waxes, and by splitting off hydrogen chloride unsaturated compounds are obtained which can themselves be polymerized. The Specification as open to inspection under Sect. 91 states that the polymerization can be carried out under the influence of light, heat, oxygen or other agent known for the polymerization of acrylic and vinyl compounds, and that lower boiling symmetrical dichlorethylene is prepared by subjecting higher boiling symmetrical dichlorethylene to the action of agents known for the polymerization of vinyl and acrylic and that the higher boiling compound is prepared from the lower boiling compound in the same way.
