  • Patent number: 11919365
    Abstract: A method of operating a vehicle climate system when an ambient temperature is below a threshold temperature is provided. In response to an ambient temperature being less than a threshold temperature, a controller is adapted to operate a blower motor at a voltage that depends on whether the vehicle is in charge sustain mode or charge deplete mode. In response to an ambient temperature being greater than a threshold temperature, the controller is adapted to operate the blower motor at a voltage that does not depend on whether in the charge sustain or charge deplete modes.

  • Patent number: 7699117
    Abstract: A nondestructive retrofit fire sprinkler protection system including a sprinkler fitting with a unique shape that inserts behind a wall surface and that securely connects a sprinkler head emerging from a wall location to preferably concealed sprinkler piping located in a room at a point where the ceiling surface meets a wall surfaces. In addition, a room coupler fitting is adapted to be inserted between wall structures to connect sprinkler piping in adjacent rooms.

  • Publication number: 20080016811
    Abstract: A fire protection mounting system that facilitates the installation of a fire protection system and a decorating feature such as a crown molding. In a two-piece embodiment one set of hanger elements secures the sprinkler pipe to the wall/ceiling junction, while the second hanger elements are secured to the crown molding. The two hanger elements have mutually engaging surfaces by which the crown molding is secured in place at the wall/ceiling junction. An alternative embodiment has a single hanger element having a surface to receive the inner surface of the crown molding and an opening to receive the sprinkler pipe. These three elements are mounted to the wall/ceiling junction to provide a decorative effect and to achieve some element of thermal protection for the pipe in the case of a fire occurrence.

  • Patent number: 4919743
    Abstract: A method of laying carpet to avoid seam peaking, the method employing an enhanced width seaming tape spanning the abutting edges of the carpet forming the seam. The tape has a hot melt adhesive on the upper surface facing the carpet backing. An enhanced width carpet seaming iron is employed to melt the adhesive and to provide a bond between the tape and the carpet backing. In an alternative embodiment, the tape is made in three segments with one of them applied spanning the seam and the other two in flanking positions along either side of the seam spanning tape. In another embodiment the seaming tape is constructed with a composite modulus of elasticity which varies across the width of the tape. The invention also includes several embodiments of the enhanced width seaming iron for application of the tape to the carpet seam.
