  • Patent number: 5512836
    Abstract: A solid-state fringe effect capacitive proximity sensor is described which lends itself to use for surface mounting and other space constrained applications. The sensor comprises an insulating substrate having a plurality of sensing electrodes formed thereon and without any screen elements therebetween. The electrodes are adapted to measure the proximity distance of a target object (conductive or non-conductive) by means of the fringe capacitance effect created between the electrodes. Capacitance measurement processing circuitry is electrically connected to the plurality of sensory electrodes.

  • Patent number: 5500456
    Abstract: A new tire sealant and inflator composition is described which utilizes a sealant having superior performance, presented in a water-based carrier, and with an inflator composition consisting of mainly dimethyl ether, modified by trichloroethylene and nitrogen gas. The composition comprises a terpolymeric latex sealant emulsion, prevented from coagulating or vulcanizing in the dispenser by the addition of additives, and made more potent by the inclusion of certain wood flours having selected particle size distributions. Other ingredients, such as propylene glycol, a surfactant, triethanolamine and ammonia, confer special attributes; for example, softening the wood flour particles and keeping them dispersed in the aerosol can, while causing them to pack down into a sealing matrix once added to a tire having a puncture.

  • Patent number: 5500082
    Abstract: Disclosed is a method of removing ink from xerographically printed paper. The method comprises pulping said printed paper in an aqueous slurry at a non-acidic pH to a consistency of about 8% or less. Next, added to the pulp slurry is a sufficient amount of long chain alcohol, the long chain alcohol having a melting point above room temperature, for a time sufficient with heating at a temperature sufficient, whereby an agglomeration of long chain alcohol and ink particles is formed. Next, the heating is stopped whereby the agglomeration solidifies into particles that settle to the bottom of the pulp slurry. Then, the agglomeration of solidified particles is removed from the pulp slurry thereby leaving a remaining slurry of deinked paper fiber and water. Optionally, the remaining slurry is subjected to flotation to remove substantially any remaining minute ink left particles behind after the agglomeration.

  • Patent number: 5488968
    Abstract: A fluidizing apparatus, such as a winterizing apparatus, and related method for preventing freezing of water in the water pipes of a dwelling. The apparatus includes a pump, an inlet line, an outlet line, a pressure switch, and an air compressor tank. The outlet line is connected to a faucet of the water pipes of the dwelling and the inlet line is positioned in a container of fluid, such as antifreeze. When a second faucet is opened, the pump is activated, and the pump will then cause antifreeze to flow from the container, through the inlet line, the pump, and the outlet line, and then into the faucet and through the water pipes of the dwelling. An associated air compressor tank is in fluid communication with the pressure switch and exit line, and cooperates with the pressure switch to maintain consistent pumping of the antifreeze. After antifreeze is in the pipes, a shut-off valve in the exit line is closed and/or the at least one valved water outlet is closed, which causes the pump to deactivate.

  • Patent number: 5474794
    Abstract: A method for the rapid cooling of a raw egg in a shell, the shell egg being warm and having an internal temperature typically of about room temperature or higher. The method preferably involves placing the shell egg for about 1 to about 5 minutes in an atmosphere of cryogenic gas at a temperature of about -60.degree. F. (about -51.degree. C.) to about -120.degree. F. (about -84.degree. C.), whereby the internal temperature decreases sufficiently to inhibit residual pathogenic and/or spoilage microorganisms, such as Salmonella and/or Pseudomonas, respectively, present inside the shell egg. Also a cool raw shell egg in a shell that has been rapidly cooled in an atmosphere of cryogenic gas after having been warmed, typically to where the shell egg had an internal temperature typically of about room temperature or higher. The cool shell egg that has been so subjected to rapid cooling has fewer viable residual pathogenic and spoilage microorganisms, i.e.

  • Patent number: 5460682
    Abstract: A method of midspan or end entry accessing of one or more selected optical fibers carried by an optical ribbon fiber. The top and bottom surfaces of a first selected span of the optical ribbon fiber are friction abraded to initiate delamination of the bond between the optical fibers and the matrix encapsulant. The delamination is completed by applying a rolling force to the circumference of the first selected span, and the delamination is then propagated by introducing the first selected span into the bore of a die element and urging the die element along a relatively longer second selected span of the optical ribbon fiber. With the delamination completed, the tip of an elongated tool is inserted through the encapsulant within the second selected span and between one or more selected optical fibers and the remaining optical fibers within the optical ribbon fiber.

  • Patent number: 5454603
    Abstract: Provided is a co-axial hydraulic hose assembly having a co-axial hose coupling releasably joining an inner hose and an outer hose of the assembly in a fluidly sealed engagement. The coupling construction comprises an end seal nut that securely fixes each end of the inner hose to each respective end of the outer hose, but which may be removed so that the inner hose may be removed if it has ruptured. Thus, a ruptured inner hose may be removed and replaced with a new inner hose inside of the original outer hose, and then the end seal nut is replaced at each end of the hose assembly to secure the two hoses releasably together in a fluidly sealed engagement, thereby allowing for continued use of the repaired co-axial hose.

  • Patent number: 5452584
    Abstract: Disclosed is an improved method for freezing biological specimens, such as human tissues, animal tissues, and plant tissues. The specimens are frozen so that they may be presently examined with light microscopy, or first stored frozen at ultra low temperatures and then later examined with light microscopy. The specimens are prepared with a matrix gel and then frozen with a fluorinated carbon fluid that is non-toxic to humans and thus the method does not present adverse health effects to humans. Preferably, the fluid also is non-flammable. More preferably, the fluid also has an ozone depletion potential of 0, whereby the preferred procedure is free of detrimental effects on the protective ozone layer of the earth. A suitable fluorinated carbon fluid is one that stays in the liquid state at low temperatures, for instance -60.degree. C. or lower. A suitable material is the perfluorinated carbon fluid, C.sub.6 F.sub.14.
