  • Patent number: 9435680
    Abstract: Apparatuses and methods for fuel level sensing are described herein. An example sensor includes a sealed housing comprising a first end, a second end, and an interior defined by walls extending therebetween. The sensor includes a float surrounding an exterior of the sealed housing and is configured to move longitudinally along the sealed housing between the first end second ends. The float may include a magnetic element configured to provide a magnetic field. The sealed housing may include an electrically conductive spring coupled to at least one of the first end or the second end, and may include a ferrous element coupled to the electrically conductive spring and configured to be displaced relative to the sealed housing based on the magnetic field. The electrically conductive spring may expand and retract to adjust a resistance of the electrically conductive spring in response to the ferrous element being displaced.

  • Patent number: 9398698
    Abstract: A pattern of an electrically conductive print material is formed on a receiver element using an elastomeric relief element that has a relief pattern comprising (1) an uppermost relief surface, and (2) an average relief image depth of at least 50 ?m relative to the uppermost relief surface. A printable material composition is applied to the uppermost relief surface, which printable material composition contains an electrically conductive print material and a carrier liquid. At least 50 weight % of the carrier liquid is removed from the uppermost relief surface, leaving the electrically conductive print material on the uppermost relief surface. Either the elastomeric relief element or the printable material composition on the elastomeric relief element, or both, are treated with an acid in vapor or liquid form to improve conductivity of the electrically conductive print material after it has been transferred from the uppermost relief surface to the receiver element.

  • Patent number: 9233523
    Abstract: The device for sealing together a formed bottom sheet and a lidding sheet between a feed roll and a sealing roll has a heating unit for preheating the lidding sheet before the sealing operation. The heating unit is a contactless induction heating device which has coils and magnetic-field influencing elements which are arranged transversely to the travel direction of the lidding sheet and opposite at least one of the coils. The distance between each of the magnetic-field influencing elements and the at least one coil is adjusted by a control unit on the basis of measurement values of temperature sensors arranged downstream of the magnetic-field influencing elements in order to regulate the temperature profile of the lidding sheet.

  • Patent number: 9228749
    Abstract: A heating wire support meshing and a method of constructing a heated surface, particularly a floor surface therewith, is described. The heating wire support meshing comprises one or more mats formed by transversely spaced parallel rows of wire support bridge elements interconnected together at their crossings. The bridge elements have electric heating wire support slots to receive and guide one or more electric heating wires along one or more desired paths. Bottom support formations extend along a bottom planar surface of the mat. Top support formations lie in a top planar surface of the mat. The wire support slots are adapted to support the one or more electric heating wires spaced below the top support formations. The support meshing also acts as a reinforcement of a sub-floor on which the support meshing is installed.

  • Patent number: 9222699
    Abstract: A rubber heat pad is integrated into a fiberglass fiber insulator to form a heater blanket for a diesel fuel filter and other truck components. A controller monitors ambient temperatures and pad temperatures and the battery flow state. If it is cold, and the battery has available power, then a heat pad(s) is turned ON. When the pad(s) gets too hot, then it is turned OFF by the controller. Truck park mode allows AC power. On the road use triggers an inverter to supply AC to the pads.

  • Patent number: 9103181
    Abstract: A heater cable for hydrocarbon drilling tubing, preferably applicable to pressurized or flooded annular space shale type wells, to prevent and/or remove obstructions in petroleum production wells tubing, caused by the accumulation of substances such as paraffin and hydrates or by a sharp increase in viscosity of the type which extends alongside a metallic thermo conductor duct affixed to the tubing by means of fixation elements. The cable is formed by an inner sheath insulating the electrical conductors, a metallic coat on said conductors' insulating sheath, a fluoropolymeric jacket surrounding said metallic sheath and an outer armor generally defined by a spring which surrounds the jacket in a helicoidal way. The coating of the conductors' insulating sheath is defined by a laminar band which protects all the surface of said sheath arranged in a surrounding way alongside it following a helicoidal arrangement and whose successive spirals are partially overlapped between them.
