Abstract: A membrane assembly for fluid separations consisting of a compact stack of alternating layers of membrane [116] with layers of fluid conducting materials [112, 118]. The assembly consists of a simplified and improved plate and frame apparatus. The stacked assembly may be placed into a pressure containment device [84] consisting of standard pipe with standard methods of closure [82, 86, 88, 90, 92, 94, 96]. Internal fluid conducting passages [108, 124, 126, 132, 140, 144, 146] are formed from cutouts [12, 14, 16, 34, 36, 38] in the stacked layers thereby greatly simplifying the manufacture and assembly of large diameter fluid separation devices using membranes to effect the fluid separation. The fluid pathways are such that the membrane assembly is particularly efficient in separation.

Abstract: A method of splitting a soluble oil effluent, in which the effluent is applied to a coarse separator and then mixed in successive stages with a polyelectrolyte and a coagulant, the resultant flocculated oil/water phase then being treated in a dissolved air flotation unit whereby to separate and recover the oil and water fractions. A coagulating tank may be provided immediately downstream of the mixer stages for the mixture to dwell for a period and a clarifier tank may follow the coagulating tank, again to provide a dwell period for the separating mixture, the floating oil being recovered so as to provide a cleaner/clearer mixture for the dissolved air flotation unit. Oil concentrations of 0.1% to 25% in the effluent may readily be treated from which substantially oil free water (oil level of the order of 0.01%) may be obtained. With further processing, "polishing," this may be reduced again eg to 0.003%. Further, the chemical oxygen demand on the water course with this much cleansed effluent is reduced by a significant factor (about 8) compared with practice hitherto.

Abstract: The disclosure relates to a technique for effectively floating the rotor (37) of a disc drive motor, thereby permitting small motions in the axial (non-critical) direction while maintaining significant stiffness of the radial (critical) direction. This is achieved by providing an electromagnetic actuator inluding a stepper motor having a housing, a stator located within the housing, and a rotor (37) positionable relative to the stator driving a motor shaft to wind and unwind a band (14) and thereby position the carriage. The drive shaft (12) passes through ball bearings (30) which support the shaft for rotation. The ball bearings themselves fit within an annular end bell portion (39) of the motor housing which defines a channel for the bearing. An injected elastomer (33) forms a tight-fitting ring between the bearings and the internal wall of the end bell (39), thereby radially supporting the outer race of the bearing. Preload springs (36) are then installed on both sides of the rotor between the internal end walls of the end bells and both outer races of the bearing. the installation of these springs effectively floats the rotor to allow some distortion of movement of the rotor in the axial direction, while minimizing or eliminating the radial deflection components.

Abstract: A cannula insertion needle (50) projects from the "forward" end of a hollow handle (10). After use to start a cannula, the needle is released from the end of the handle and its sharp end (52) retracted into the handle, beyond reach. Preferably the handle has an aperture (23) big enough for the needle but too small for fingertips. In one preferred form of the invention, the needle rides in a carrier block (30) that slides inside the handle. Initially the block is secured in the handle against the forward end, with the sharp end of the needle protruding outward through the aperture. A manually releasable latch (40) holds the block in this position. The latch mechanism includes mutually interfering stop elements on the exterior of the block and interior of the handle. After the cannula is in place, the person using the device withdraws the needle from the patient and manually triggers the carrier-block latch (42) by squeezing or rotating one of the stop elements out of engagement with the other. Then a coiled spring (61) drives the block rearward to retract the needle into the handle. At the rear end of the handle a stop (13) halts the carrier block and needle so that they are safely confined within the handle. A standard size tube fitting on the rear of the handle and a hollow needle permit liquid flow to or from the patient through the handle temporarily. <IMAGE>

Abstract: The invention concerns apparatus for molding thermoplastic tubing having solid annular ribs. The apparatus is of the type where a tubular mold is defined by cooperatively interengaged mold block of a pair of mold assemblies. An annular extrusion orifice for the tube extends into the mold tunnel and tubing is extruded about a mandrel. The invention provides an accumulator chamber in the region of the extrusion nozzle to provide for pressure differences which build up at that point. Thus, the effective volume of the accumulator chamber can compensate for the varying requirement for the thermoplastic material resulting from the varying radial wall thickness.
