The invention is an electrostatic coalescer testing apparatus for testing the ability of chemical additives to facilitate electrostatic coalescence of water in a water hydrocarbon-containing mixture. The apparatus includes: (a) a plurality of tubular containers for containing the water-hydrocarbon mixture, each of the tubular containers having one open end and one closed end, and made of a material not substantially electrically conductive; (b) a heating block/electrode having a plurality of tubular recesses therein, each of the tubular recesses for receipt of one of the tubular containers disposed closed-end down, the heating block/electrode comprising of a heat conducting and electrical current conducting material, for conducting heat to the tubular containers, and for applying an electrical potential across the water-hydrocarbon mixture; (c) a mixing blade/electrode member disposed within each of the tubular containers for mixing the water-hydrocarbon mixture with the chemical additive, and for applying an electrical potential to the water-hydrocarbon mixture; (d) a transformer means having two poles for applying an electrical potential to the two electrodes wherein; one pole is connected to the mixing blade/electrode; and one pole is connected to the heating block/electrode.

The invention relates a mixer assembly for mixing liquids in a tubular container including: (a.) an electrically conductive central shaft member, (1) having a top end portion and a bottom end portion; (2) where the central shaft member is oriented longitudinally along the length of the mixing blade assembly; and (3) wherein the central shaft member is threaded along at least a portion of its circumference; (b.) a plurality of shearing members fixedly attached to the central shaft member for shearing the liquids when the shaft member is rotated; (c.) a vortex breaker member positioned below the blade members and above the bottom end portion of the central shaft member; wherein the vortex breaker member comprises: (1) a concave-shaped disk having an aperture substantially at its center, (2) wherein the central shaft member is positioned through, and fixedly attached at, the aperture of the vortex breaker member; (3) wherein the concave-shaped side of the vortex breaker member is oriented toward the bottom end portion of the central shaft member; (4) wherein all points along the perimeter of the circumference of the vortex breaker member are substantially equidistance from the center of the central shaft member.

Mixer assembly

Polyethercyclicpolyols are prepared by thermally condensing a polyol having at least three hydroxyl groups of which at least two of the hydroxyl groups are vicinal, precursors of the polyol, cyclic derivatives of the polyol, or mixtures thereof, and controlling process conditions to avoid substantial undesirable degeneration.

Thermal condensation of polyhydric alcohols to form

A funnel device is provided for emptying liquid from scintillation vials and disposing of the empty vials. The device has a top provided with rows of holes to loosely accommodate standard liquid scintillation vials. Beneath each row of holes is a rod. The vials are placed, inverted, through the holes to rest on the rod beneath. After the vials have drained into an appropriate container, the device is moved to rest on a vial collection container, and the rods are removed, allowing the vials to fall into the collection container.
