Abstract: Cooling means for a heated surface comprising an enclosure for enclosing the heated surface and two oppositely charged interleaved radial arrays of microelectrodes positioned on the surface within the enclosure. The combined arrays have a closely spaced end and a periphery end. A volatile cooling liquid is contained in a reservoir within the enclosure but separate from the array. A slit-type restrictor is positioned between the reservoir and the array to restrict liquid flow from the reservoir toward the array. A portion of the closely spaced end of the array is positioned within the slit whereby the pumping action of the array draws only the amount of volatile liquid along the electrodes needed to form a thin evaporating film over the array area. The vapor from the thin film evaporator flows to a condenser where it is cooled, condensed to a liquid and returned to the liquid reservoir.

Abstract: A process for effectively mechanically disrupting fiber pellets produced from waste carpet material into their individual strands and for insertion and uniform distribution of such fibers through congealable materials such as asphalt and concrete, thereby providing improved physical properties to the resultant solids and, by providing a use for such waste carpeting, minimizing their deposition in landfills.

Abstract: Means for cooling a heated surface comprising an enclosure for enclosing the heated surface and two interleaved radial arrays of micro electrodes positioned on the surface within the enclosure thereby forming an interleaved radial array. The radial array has a ‘near-vertex’ end and a periphery. The micro electrodes at the near-vertex end have a smaller interelectrode distance and the micro electrodes at the periphery have a larger interelectrode distance. A volatile cooling liquid is contained within the enclosure and moved from the near-vertex array end toward the periphery along the lengths of micro electrodes by non-alternating voltages applied to the micro electrodes, thereby creating a polarization effect and evaporation of the volatile liquid.

Abstract: An optically based liquid level (liquid-vapor) detector for use with a window having a substantially planar side facing the liquid-vapor side and a substantially planar side positioned parallel to the liquid-vapor side facing the outside. The detector comprises a light source positioned on the outside of the window to direct its light through the outside planar side to the inside planar liquid-vapor side and a light detector positioned on the outside of the window to receive light transmitted from the source and returned from the planar liquid-vapor window side. The detector further includes electronic means for detecting the light intensity change affecting the transducer, from the condition of liquid on the liquid-vapor side, to the condition of vapor on the liquid-vapor side of the window, whereby an action or signal is generated in response to such change.

Abstract: A non-fouling liquid level detector and control especially for a sealed system likely to have iron particle contaminants. The device employs a float projecting above the liquid level and bearing above the liquid level a unmagnetized ferromagnetic tell-tale. A magnetic field is generated by a magnet positioned outside the sealed system. The magnetic field extends around the float and tell-tale through a magnetically permeable partition comprising a wall of the sealed system that is positioned between the magnet and the float. The float position is monitored by a magnetic field sensor such as a Hall Effect device positioned adjacent the magnet, outside the sealed system. The sensor responds to the movement of the tell-tale. The output of the sensor is employed to control the monitored liquid level.

Abstract: A cooling system employing Micro Electro Mechanical System (MEMS) technology and polarization principles to move a cooling fluid over a surface requiring cooling and further employing electrohydrodynamic principles for the purpose of enhancing the heat transfer coefficient between the cooling fluid and the surface to be cooled.

Abstract: A device for removably holding and pressing a holder or carrier, supporting a graphics or textual display, against the interior of a raisable auto window by means of a leaf spring hooked over the top edge of the window and configured to exert force against the carrier when raised.

Abstract: A process and machine for receiving and processing to a transportable and usable condition, water soaked waste dredge removed from watery bodies. The process includes the steps of separating oversize material from the watery bulk waste, grinding organic oversize material to pulp, adding the pulp to the watery bulk, adding stabilizers to the bulk, conveying the aggregate to a transporting vehicle and performing the mixing process within the vehicle. The process further includes transporting the mixture to a point of use, spreading the mixture, spreading a pozzolanic binder on the mixture and mixing the binder with the mixture in situ.

Abstract: A screw device for imposing spreading forces on opposing surfaces, having a pin adjustable length and employing a rod member having a groove in the end for engaging the pin.

Abstract: A refrigeration system having compressors positioned higher than the dispersed evaporators requires multiple suction risers. To better ensure oil return to the compressors, only a single oil return riser is employed. This oil return riser is connected to one end of an oil collection main positioned near the lower portion of the suction risers. The oil collection main is connected by restricted oil drain conduits to the lower portions of the suction risers, thereby collecting the oil which failed to be conveyed to the top of the suction risers by their vapor velocity. The restrictions in the oil drain conduits ensure adequate vapor velocity within the oil collection main even with widely varying loads on the suction risers.

Abstract: A reverse cycle refrigeration apparatus for air dehumidification is employed having an evaporator and a condenser and employing first and a second heat transfer coils for this purpose. Both coils are positioned in the air stream. In a first cycle the second coil functions as the evaporator for cooling and dehumidifying the air stream and accumulating frost and the first coil acts as the condenser, warming the cooled and dehumidified air stream and thawing frost having accumulated on it. In a second cycle the first coil acts as the evaporator, cooling and dehumidifying the air and providing the heat for defrost and the second coil acts as the condenser, thereby being defrosted. Dampers are provided for stopping air flow over the defrosting coil.

Abstract: A heat transfer coil for exchanging heat between a primary fluid and a secondary fluid. The coil has a series of substantially parallel tubing runs. The primary fluid flows within the primary tubing. The secondary fluid flows outside the primary tubing and in contact with it. A heat pipe having a length has a first portion residing within a primary tube and a second portion residing outside the primary tube but adjacent and parallel to it. The secondary fluid thereby exchanges heat with the primary fluid both through the primary tube and through the heat pipe.

Abstract: A device for attaching or placing on the wrist for the purpose of securely holding one end, the receiving end, of a bracelet while the other bracelet end having a catch or clasp, is fastened to the held end. The device thereby allows the wearer to correctly and securely install the bracelet on his/her own wrist without anyone's aid. The device includes an elastic wrist band and means secured to the band for holding the bracelet end. The bracelet end holding means includes a folded portion having opposing hook and loop matrixes within which the bracelet receiving end is placed before the hook and loop matrixes are pressed together, thereby securing the bracelet receiving end to the folder and to the wrist band.

Abstract: A method for processing water-bound wastes and for adjusting quantities and for combining ingredients to achieve a desired mechanical property of the mixture. The process includes the establishment of at least one input parameter for the ingredients. The ingredients include heated granular solids and contaminated water-bound wastes. The mixing process causes the water-bound waste to be heated to a temperature which assures neutralization or purification of any waste borne contamination and which simultaneously cools the granular solid.
