Abstract: A liquid-liquid extraction process that uses counterflowing liquid phases, especially in conjunction with a reciprocating plate extraction column, wherein one of the liquid phases has a lower density than the other and is at least partially saturated with a dispersible gas, requires less plate stack height or a smaller column diameter when plate-to-plate spacing is non-uniform rather than uniform and such non-uniform plate-to-plate spacing includes greater plate-to-plate spacing proximate to raffinate liquid discharge than proximate to feed of the lower density liquid phase.

Abstract: A method for extracting an intracellular peptide, protein or other polypeptide from a whole fermentation broth using a water miscible alcohol, or a water miscible or partially water miscible glycol ether.

Abstract: A process for converting a tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone.

Abstract: A method for a liquid-liquid extraction of hydrophilic organic compounds from aqueous solutions thereof is described. The method generally includes intermixing a sufficient quantity of a specified glycol ether with the aqueous liquor at a first temperature to form a suspension comprising an aqueous raffinate phase and a glycol ether extract phase; separating the glycol ether extract phase from the aqueous raffinate phase; heating the glycol ether extract phase to a second, higher temperature to form a suspension comprising an aqueous extract phase containing a portion of the hydrophilic organic compound and a glycol ether raffinate phase; and separating this glycol ether raffinate phase from the aqueous extract phase. The selected glycol ether has an inverse solubility in water and the partition ratio, value K, for the hydrophilic organic compound is greater than 0.1.

Abstract: Provided are apparatuses and processes for the removal and purification of fermentation prepared one or more volatile organic compounds. The apparatuses comprise a fermentor unit, a vacuum side stripper unit (10), and, optionally, one or more of a pressure-swing adsorption unit, a dual-function column, a dividing wall distillation column unit, and a means for inducing phase separation of a mixture of a volatile organic compound and water.

Abstract: Glycol ether acetates, and in particular propylene glycol alkyl (or aryl) ether acetates, can be resolved enzymatically by enantioselective hydrolysis with a hydrolase at high concentrations of substrates; in some embodiments, the hydrolase is a lipase. Glycol ethers, and in particular propylene glycol alkyl (or aryl) ethers, can be resolved enzymatically by enantioselective transesterification with a hydrolase, in the presence of an acyl donor, at high concentrations of substrates; in some embodiments, the hydrolase is a lipase.

Abstract: A twin screw vise utilizing two threaded vise screw rods that are journaled through flanged nuts fixed to a workbench top or to a rear, fixed bench jaw. The vise screws pass through a movable front jaw and into tee-castings and handles that may be turned to rotate the screws. Sprockets are located on each screw between the tee castings and the front jaw and are coupled by a chain. One of the sprockets is fixed in position on its screw during a calibration procedure. The other sprocket remains free to rotate on its screw, except when a spring loaded pin in the corresponding tee-casting engages a depression in the face of the sprocket, thereby coupling that sprocket to the tee casting and associated screw.

Abstract: A woodworking bench and related fixtures providing an integrated system of bench features, vises, dogs, panel clamps, hold-downs and fixtures that cooperate to provide a highly flexible workpiece holding and clamping apparatus able to accommodate a wide variety of shapes and sizes of workpieces and hold such workpieces in an enormous variety of positions during numerous different operations. Two substantial slabs provide the bench top surface and carry a rectilinear pattern (in rows and files) of round, vertical bench dog holes. The rectilinear pattern of round bench dog holes with specific, equal spacing between holes, and similar holes in the edge of the top, facilitate great flexibility in clamping using conventional round dogs in the bench top holes and corresponding dogs in bench edge-mounted, or end-mounted vises. Such holes also accommodate other clamping, fixing and hold-down fixtures that contribute to flexibility and utility.

Abstract: A hold-down utilizing a round, interchangeable post having annular barb-like ridges or projections that engage a workbench top through round holes that may be located at substantially any desired positions in the bench top. The post threads into a hold-down body having, on one side of the post, a yoke within which a gooseneck-shaped hold-down arm pivots on a pin received in yoke arms or forks and, on the other side of the post, a screw pressure point and T-shaped slot for receiving the head of a clamping adjustment screw that is journaled through one end of the clamping arm. The other end of the clamping arm terminates in a foot with a rounded pad for exerting pressure against a workpiece.

Abstract: A vise for holding a workpiece, comprising a pair of generally opposed jaws having substantially planar faces, a clamping screw having at least one external thread centered around a longitudinal axis rotatably attached at one end to one of the jaws and passing through the other jaw, a clamping screw nut having at least one internal thread occupying an arc of no more than approximately 180.degree.

Abstract: A hinge drilling jig for use in the "32 mm" or face-frameless system of cabinet construction for locating and drilling the hinge cup and the hinge cup mounting screw holes to be drilled in a cabinet door. A flat bottom drill bit is slideably retained in a jig body for drilling the hinge cup hole, and two thumbscrews locate the jig on the face of the cabinet door relative to its vertical edge. A collar retains the drill bit in the body and a shoulder on the drill bit and annular rings cut on the shank of the drill bit allow measurement of the depth of the hinge cup hole prior to being drilled by the drill bit. A plurality of countersinks on the body locate the position of the hinge mounting screw holes on the face of the cabinet door in predetermined positions. The jig is held in position on the door by a handle or a clamping arm having a clamping screw and a gauge assembly locates the jig on the face of the cabinet door relative to the second edge.

Abstract: In a pressure swing adsorption system used to recover an oil-soluble solvent, monomer or hydrocarbon vapor such as 1,1,1-trichloroethane or styrene from a gaseous stream such as air, an oil-sealed vacuum pump may be used without substantial absorption of vapor into the oil if the oil in the pump is heated to a temperature substantially above the dew point of vapor in the gas stream leaving the pump.
