Abstract: VENTURI BARGE UNLOADING SYSTEM       ABSTRACT OF DISCLOSURE               A system, apparatus and method for unloading dry, bulk, particulate material from a ship, barge or the like into a pressure vessel and thereafter transferring the material into a storage container such as a silo. A venturi has primary and secondary inlets with the primary inlet connected to a blower and the secondary inlet connected to the pressure vessel. Air from the blower is forced through the venturi primary inlet to create a flow of primary air through the venturi and to induce a suction at the venturi secondary inlet. The suction is coupled to the pressure vessel thus drawing the particulate material into the pressure vessel. After the pressure vessel is full, air from the blower is forced into the pressure vessel to transfer the material from the pressure vessel to the silo. The steps of filling the pressure vessel and transferring the material from the pressure vessel to the silo are repeated in alternating sequence. During the transfer of material from the pressure vessel to the silo, the venturi is by-passed to terminate both the flow of primary air through the venturi and the induced suction in the pressure vessel.

Abstract: ABSTRACT   A process for the manufacture of halogenated hydrocarbons which comprises contacting a hydrocarbon or halogenated hydrocarbon feedstock with a solution of a halide carrier to halogenate the feedstock whereby the halide carrier is reduced to a spent carrier and regenerating the halide carrier by electrolysis of the spent carrier solution from the halogenation reaction by electrolysing the spent carrier solution  in the presence of halide ions under conditions whereby deposition of metal or metal salts and liberation of elemental halogen are substantially avoided. In particular embodiments, the feedstock is halogenated using a non-aqueous solution of the halide carrier in which the ratio of halide ion: metal ion of the halide carrier is below 2:1, preferably about 1:1 and regeneration of the halide carrier is carried out in a three-compartment cell having two ion-exchange membranes or a diaphragm and a membrane. The halide carrier is a halide salt of a metal of variable valency in which the metal is in a higher valency state, especially cupric chloride or ferric chloride.

Abstract: ABSTRACT         The disclosed invention provides apparatus for electron-beam-irradiation of surfaces for purposes of sterilization and the like.  An electric-discharge repetitive pulse generator of the Marx type having a stacked array of discharge gaps is connected to a corresponding staggered co-extensive array of capacitors.  Pulse generation is achieved by initially triggering other than the first discharge gap.  A longitudinally extending electron gun having an electron-pervious window is electrically connected to the pulse generator so that longitudinal strip-type electron beams exiting the window are drawn from the electron gun in response to generated pulses.  With the apparatus of the invention voltage variations have less effect and reliability is improved.
