Title: Membrane separation apparatus and method
Inventor: CARO RICARDO F
IPC: B01D61/46
Filed: 1988-09-29
Granted: 1993-08-03
Abstract: ABSTRACT            Continuous flow membrane separation is accomplished by apparatus adaptable for osmosis, dialysis, and electrodialysis.  For electrodialysis to separate from one another, in a single step, multiple differing molecular weight components of fluids, a series of adjoining flow chambers are all separated from one another by semi-permeable membranes and at least one of the chambers is separated from each adjoining chamber by a membrane having a molecular weight cutoff different from that of the membrane separating it from the other chamber adjoining it.  To insure that neither the crude to be processed nor the desired product comes into contact with an electrode which could be deleterious, there is provided a minimum of four flow chambers adjoining one another in sequence.            Adapted for all three separation processes is an assembly of a tubular membrane encircled by a flexible reinforcing mesh fabric with pressure in the fluid within the membrane sufficient to bulge the membrane radially and outward into the interstices of the mesh fabric to eliminate dead spots in fluid flow along the exterior of the membrane and sufficient to stiffen and straighten the membrane tube into essentially the form of a right cylinder.  For electrodialysis, one or more additional, similar, successively larger reinforced membrane assemblies, surround(s) the first assembly.  A housing encloses the membrane(s) to form a cartridge.  The membranes are spaced to avoid contact with electrodes used in electrodialysis.

Abstract: Abstract Wind Turbine Shutdown System According to the invention, a wind turbine 10 incorporates a wind vane 105 which mechanically controls a valve 100 that directs the output of a turbine driven hydraulic pump 75 to yaw the turbine out of the wind upon a loss of system power or load.  The turbine yaws out of the wind at an angular rate that is roughly proportional to rotor speed so that excessive teeter amplitudes are not encountered.  The mechanically driven pump advantageously provides power to yaw the rotor out of the wind even if all electrical power is lost.

Abstract: REFRIGERATOR     Abstract of the Disclosure The refrigeration system disclosed herein provides separate chilling and freezing compartments and operates in alternate phases.  In the first phase, an evaporator which controls chilling  compartment temperature also absorbs heat from a thermal mass through the change of phase of a liquid to a solid.  In the second phase, this evaporator becomes a condenser for the operation of a second evaporator associated with the freezer component.  During this second phase, the heat transfer is reversed, the fusion energy of the first phase is recaptured as melting energy in the second.  Accordingly, heat is transferred from the second evaporator to the mass over a temperature differential which is less than that existing between the second evaporator and the environment.

Abstract: An integral disposable absorbent article such as a diaper having a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, at least one elastically contractible gasketing cuff, and at least one barrier cuff. The barrier cuff has a proximal edge and a distal edge. The absorbent article is additionally provided with spacing means for spacing the distal edge away from the top surface of the topsheet. In addition, adhesive means secure the end portions of the barrier cuff closed. A channel is formed between the proximal and distal edges in at least the crotch region because the distal edge is spaced away from the topsheet top surface.When the diaper embodiment of the present invention is applied to a wearer, the barrier cuff rides up along the inner thighs and the perineum of the wearer in the crotch region and along the buttocks in the back waist region. Leakage prevention is enhanced because body exudates which are not immediately absorbed by the absorbent core contact the barrier cuff and are contained and held within the channel so that they do not wick out of the diaper or flow out of the gaps between the diaper and the legs or waist of the wearer. Additionally, should such exudates flow beyond the barrier cuff, leakage is further enhanced by the gasketing cuff because it forms an additional fluid impervious barrier about the leg or waist of the wearer.
