  • Patent number: 7318691
    Abstract: The present invention provides an automated-torque controlled tool for attachment to a milling machine. The tool comprises an elongated hollow housing defined by a neck section, a middle section, and a bottom section. The neck section is adapted to engage a spindle of the milling machine for rotational and axial movement therewith. A torque spring is situated within the middle section of the housing. A torque adjuster is dimensioned and configured to sit within the neck section of the housing on top the torque spring. A bit holder and driver mechanism are rotationally mounted within the bottom section of the housing. When the torque threshold is reached by the bit holder, the driver mechanism rotationally disengages from the bit holder.

  • Patent number: 7265322
    Abstract: A process for manufacturing a plastic pane provided with embedded electrical conductors, in particular a window pane, in which the conductors are joined to a surface of a plastic sheet that subsequently receives another layer of plastic by injection molding from the rear for the purpose of forming a pane body. In the process the material of the plastic sheet and the injection-molded plastic are joined together directly by mutual adhesion, and the surface of the plastic sheet that is located on the opposite side from the conductors forms one of the outer faces of the finished pane. The electrical conductors are formed by furnishing the surface of the plastic sheet with at least one metal wire which is to be exposed to the rear injection molding.

  • Patent number: 7259357
    Abstract: The invention seals, unseals and/or bonds plastics, waxes and resins via a thermal metal strip or wire coated with liquefiable substances that melt to open or separate and cool to congeal, seal, vulcanize or bond together when the wire or strip is energized in a shorted state (to heat) or not energized (to cool). Electronic switch modalities and sealing applications are optionally taught for security and tamper detection. In one modality, a unique signal is sent to the gate leg of a micro-processing chip (e.g. an SCR switch) where firmware recognizes the signal and permits current through a thermal wire. This innovation is optionally employed for Homeland Security.

  • Patent number: 7230205
    Abstract: In some instances, ice can form on the surface of a compressor airfoil. If the ice dislodges, it can impact and damage other compressor components. Aspects of the invention relate to systems for detecting the presence of ice or water on a compressor vane during engine operation. A ceramic insulating coating can be deposited on a portion of the surface of the vane. A heater and a thermocouple can be provided near the outermost surface of the coating such that the thermocouple can sense heat from the heater. The heater and the thermocouple can be provided within the coating. The presence of water film and/or ice on the coating surface can be detected by taking a thermocouple measurement following a heater pulse. The presence of a water film or ice results in a delay in the temperature rise detected by the thermocouple.

  • Patent number: 7230214
    Abstract: A metal sheathed heater utilizes splice connections that connects ends of a heater cable with ends of a lead wire. Each splice connection has a connector that connects core wires of the lead wires and heater cable together. Heat shrinkable tubing surrounds the connector and ends of the heater cable and lead wires. An adhesive is interposed between the heat shrinkable tubing and heater cable and lead wire ends to bond with the heat shrinkable tubing and complete the splice connection. The metal sheath of the heater can be formed with an enlarged diameter portion to account for the heat shrinkable tubing surrounding the lead wire and heater cable ends.

  • Patent number: 7214906
    Abstract: An apparatus for the independent control of the amount of heat produced by a right and a left side heated hand grip includes a control panel with various input buttons and a pair of LEDS that each indicates a relative power setting of one of the heated hand grips. A microprocessor receives input instructions from the input buttons and provides a first pulsed DC output having a desired duty cycle to one of the heated hand grips and a second pulsed DC output having either the same or a different duty cycle to a remaining one of the heated hand grips, thereby controlling the amount of heat produced by each respective heated hand grip. This improves comfort. Reverse polarity protection, a return to previous power settings, including a remembrance of a differential between the two heated hand grips, and automatic shutoff when battery voltage reaches a predetermined value are described.
