Abstract: A push plate assembly sends a signal to a receiver. The push plate includes a housing, a push plate, a signal generator, a biasing member, a first latch element, a second latch element, and a button. The push plate is movably mounted to the housing. The signal generator includes a switch. The switch is in electrical communication with circuitry through which a signal is transmitted. The biasing member is disposed between the push plate and the signal generator. The biasing member biases the push plate away from the signal generator. The first latch element is connected to the push plate. The second latch element is disposed in the housing. The first latch element and the second latch element engage with one another to limit the movement of the push plate away from the signal generator as the biasing member acts on the push plate.

Abstract: The subject invention relates to a power sprayer that can be conveniently used by both professionals and amateurs. This power sprayer offers flexibility of movement because it can be battery operated. It also is designed to eliminate the need for cleaning its spray nozzle after being used. The media being sprayed can also be easily changed quickly. For instance, paint colors can be changed quickly and repeatedly by simply changing the media cartridges that are adapted for simple attachment to the sprayer. The media cartridges used in conjunction with the sprayers of this invention can also eliminate the inconvenience associated with refilling conventional power sprayers with a desired media.

Abstract: A door latch actuator includes a housing, a latch bolt pin actuator, and a spring latch bolt actuator. The housing includes a strike plate defining a latch opening. The latch bolt pin actuator is mounted for movement in the housing between a first extended position and a second retracted position. The spring latch bolt actuator is mounted for movement in the housing between an extended position and a retracted position.

Abstract: A gun safety device includes a barrel plug assembly having a first compression member, a second compression member, an expansion member, a joining member, and an adjustable extension rod assembly. The expansion member is sandwiched between the first compression member and the second compression member. The joining member is operatively linking the first compression member to the second compression member. The joining member is adapted to draw at least one of the compression members towards the other compression member. The adjustable extension rod assembly extends from the second compression member.

Abstract: An adjustable strike plate assembly includes a door strike housing and an insert plate. The door strike housing includes a strike plate having an opening and walls depending from the strike plate to define a cavity. The insert plate is adapted to mount to at least one of the walls and be received in the cavity to change the effective dimensions of the cavity.

Abstract: A gun safety device includes a barrel plug assembly (A) which is installed in a barrel of a gun. The barrel plug assembly (A) has an expansion tube (14), a pair of compression members (12, 16) and a joining member (10). The expansion tube (14) applies a force radially outward when compressed longitudinally. The pair of compression members (12, 16) are arranged at opposite ends of the expansion tube (14) and are rotationally fixed with respect to one another. The joining member (10) operatively links the compression members (12, 16) together and selectively draws them together to longitudinally compress the expansion tube (14) therebetween. The gun safety device also includes a wrench assembly (B) which is selectively attachable and mated to the barrel plug assembly (A). The wrench assembly (B) operates the joining member (10).

Abstract: A method and apparatus for controlling NO.sub.x produced by a natural gas fired combustion source includes establishing a control curve for the combustion source for indicating NO.sub.x levels based on steam injection rates and fuel flow rates provided to the burners. The atomizing steam injection flow rate provided to the burner is measured as well as the fuel flow rate. A NO.sub.x level is determined for the combustion source based on the atomizing steam injection flow rate, the firing rate, and the fuel flow rate. NO.sub.x levels are lowered by adding atomized steam to the burners according to the pre-programmed control curve.
