Abstract: A self-contained, portable liquid chemical supply tank storage and transfer unit includes an external support shell having upper and lower support shell sections concentrically joined to one another. The upper support shell section includes diametrically opposed upright arms which define therebetween a generally U-shaped space in which the transfer system is positioned. The lower support shell section houses a liquid chemical storage tank. The transfer system includes a metering canister fluid-connected to the liquid chemical within the storage tank, a selector valve assembly and a pump (preferably a manually-actuated hand pump). Operation of the pump will allow liquid chemical to be drawn from the storage tank and into the canister. The liquid chemical in the metering canister may then be transferred (e.g., via gravity or another pump) to another tank, for example, a mixing tank associated with an agricultural spray implement.

Abstract: A novel Phillips catalyst for the copolymerization of ethylene with .alpha.-olefins, contains, as a catalytically active component, a finely divided, aluminum silicate-supported, phosphorus-containing chromium catalyst. This can be prepared by applying at least one organic phosphorus(III), (IV) and/or (V) compound and at least one chromium(III) compound which does not react with said phosphorus compounds under the reaction conditions used, in succcession in any order or simultaneously, to a finely divided aluminum silicate hydrogel or xerogel with formation of a catalyst intermediate and activating the catalyst intermediate at elevated temperatures in an oxidizing atmosphere, with the result that the chromium catalyst is formed. The novel Phillips catalyst gives ethylene/.alpha.-olefin copolymers in which the comonomers are more uniformly distributed over the copolymer chains than is the case with ethylene/.alpha.-olefin copolymers which have been prepared with the aid of conventional Phillips catalysts.
