  • Patent number: 10129932
    Abstract: A sensing element for sensing a temperature of an electrically heated window includes a coil of filament wire having a first end and a second end, the coil having a resistivity that changes based on temperature, a first substantially flat conductive material electrically coupled to the first end of the coil, a second substantially flat conductive material electrically coupled to the second end of the coil, a first lead wire electrically coupled to the first substantially flat conductive material and extending outwardly, and a second lead wire electrically coupled to the second substantially flat conductive material and extending outwardly.
    Type: Grant
    Filed: June 23, 2015
    Date of Patent: November 13, 2018
    Assignee: PPG Industries Ohio, Inc.

  • Patent number: 8177205
    Abstract: A mechanical device for displacing jaws of a spring biased clamp includes a housing for receiving handles of the spring biased clamp. The housing has a platform moveable toward and away from a wall to move the handles of the clamp toward and away from one another, to move the jaws of the clamp away from and toward one another, respectively. A control member activates and deactivates a force applying member operationally connected to the platform, wherein activating the force applying member moves the platform toward the wall and deactivating the force applying member moves the platform away from the wall of the housing. The device is used to apply clamps to marginal edge portions of a stack of two one or more sheets to provide a clamped subassembly. The clamped subassembly in one embodiment is laminated to provide an aircraft transparency.
