Abstract: In forming an electrophoretic gel, various defects can be induced by the shrinkage that generally accompanies polymerization. These defects can include pulling away from a vessel wall or voids or bubbles forming within the gel itself. Prior to polymerization, a monomer can be compressed to a density at least equal to that of the expected density of the final gel, which then is substantially free of such shrinkage defects. The disclosed method is readily generalizable to other situations to produce polymers substantially free of defects due to shrinkage.

Abstract: An apparatus used in the pretreatment of wood chips in a process for converting biomass to a liquid hydrocarbonaceous fuel. The apparatus functions to break down the wood chips to a size distribution that can be readily handled in a slurry form. Low maintenance operation is obtained by hydrolyzing the chips in a pressure vessel having no moving parts.

Abstract: A gas flow control system in which several constituent gases are mixed and the mixture delivered through controlled injectors to a processing zone. Mass flow controllers control the injector flows with one of the controllers being a master and the other being slaved to provide a selected percentage of the flow through the master controller. The gas mix is regulated by a mass flow controller on one of the constituents and a flow meter on the other, the flow meter producing an error signal which is used to readjust the total flow through the injectors by control of the master injector flow controller.

Abstract: An olefin is polymerized in a hydrocarbon diluent in a turbulent reaction zone to produce particles of polymer which are substantially insoluble in the diluent. Fouling of the reactor by adherence of polymer particles to the walls of the reactor is reduced by adding to the reaction medium a composition which comprises a porphyrin compound, alone or together with a metal alkyl sulfosuccinate. This composition is also useful as an antistatic agent for liquid hydrocarbons and halohydrocarbons.
