  • Patent number: 9115890
    Abstract: A gas-fired heat gun is ignited using an electrode tip located downstream of a flame holder such that the electrode tip is in the path of the flowing gas. The electrode is connected to a voltage source that causes a spark to jump from the electrode tip to another part of the heat gun, such as the flame holder or a casing of the heat gun, when a trigger is pulled, thereby igniting the flowing gas. The electrode is typically a thin wire extending through a portion of a diffuser defining a portion of the gas flow path upstream of the flame holder. The electrode may be continuous from the diffuser to a terminal end downstream of the flame holder.

  • Patent number: 8444200
    Abstract: A tailgate control mechanism used to exert a force on a pivot. The tailgate may include a pivoting main body and a pivot fixed to a truck bed, where the main body may move about the pivot. The tailgate may also include a piston element including a first end connected to the pivot and a second end connected to the main body. The second end may be positioned above the first end when the main body is in a closed position. The piston element may also be configured to provide a counter force to balance the weight of the tailgate. The piston element may also be retrofitted.
