Abstract: A process/apparatus is disclosed for continuously separating a liquid medium comprising diluent and unreacted monomers from a polymerization effluent comprising diluent, unreacted monomers and polymer solids, comprising a continuous discharge of the polymerization effluent from a slurry reactor through a discharge valve and transfer conduit into a first intermediate pressure flash tank with a conical bottom defined by substantially straight sides inclined at an angle to that of horizontal equal to or greater than the angle of slide of the slurry/polymer solids and an exit seal chamber of such diameter (d) and length (l) as to maintain a desired volume of concentrated polymer solids/slurry in the exit seal chamber such as to form a pressure seal while continuously discharging a plug flow of concentrated polymer solids/slurry bottom product of the first flash tank from the exit seal chamber through a seal chamber exit reducer with inclined sides defined by substantially straight sides inclined at an angle to th

Abstract: A bevel setting tool having a rectangular plate, both sides of which are marked with reference indicia and a moveable fence that slides longitudinally on a stud that passes from the fence through a slot centrally located in the plate and into a locking knob. The fence and knob may be disassembled so that the fence can be positioned on either side of the plate.

Abstract: A honing guide and bevel setting jig for removable attachment to the honing guide to properly position the angle and projection of a tool to be sharpened in the jig to enable the tool to be honed at the proper angle and position. An adjustable roller that contacts an abrasive surface during use of the guide facilitates formation of micro bevels. A tool securing bar having a generally triangular shape in the bar's middle section forces the arris-defining back of the tool being honed against a reference surface in the guide by tightening thumb nuts around threaded studs projecting from the bar. Jigs for use with both square and skew edge chisel and blades are described. A concave surface clamp bar honing guide provides enhanced gripping of the tool being honed, and wedges and adjustable structures expand the range of bevel angles that can be honed.

Abstract: There is described a fluid treatment system comprising an array of independent fluid treatment reactors. The reactors are arranged in a manner whereby a flow of fluid may be passed through the array in a substantially helical direction. The fluid treatment system is capable of treating large volumes of fluid (e.g., water) while requiring a relatively small foot print. In essence, the present fluid treatment system concentrates a relatively large number of radiation sources in a relatively small amount of space resulting in the ability to treat large volumes of fluid (e.g., water).

Abstract: The present invention relates to the removal of hydrocarbon residues from a catalyst and more specifically the air activation of a catalyst containing hydrocarbon residues. It also relates to extruded pipe and utility conduit resins comprising polyethylene, household/industrial chemicals container resins, and to a polyethylene resin particularly suitable for large parts by blow molding and sheet extrusion procedures, wherein the resin is made by a process using an activated chromium and titanium-based catalyst.

Abstract: This invention is related to a polyethylene resin particularly suitable for large parts by blow molding and/or sheet extrusion/thermoforming procedures, wherein the resin is made by a process using an activated chromium and titanium-based catalyst.

Abstract: A containing a dimple the face the magnet and construction toys utilizing dimple-containing magnets and ferromagnetic spheres or dimple-containing ferromagnetic structures and magnetic spheres and other components.

Abstract: An out-feed roller support stand having a sturdy, stable base that folds for compact storage. A support mast that telescopes into and is adjustable within the base supports a work support head that includes an adjustable cross bar on which a row of pivoting caster wheels are mounted. An alternative embodiment includes a ramp for guiding sagging ends of work-pieces up onto the caster wheels. Both the height and angle between the adjustable cross bar and floor are adjustable after the position of the support mast has been adjusted in order to position the support head in roughly the correct location.
