Abstract: A spray nozzle includes a first conduit that provides a first flow path for a first type of fluid, a second conduit that provides a second flow path for a second fluid that is different from the first fluid, a first dispensing aperture that ejects therefrom a spray that includes the first type of fluid and/or the second type of fluid, and at least one balancing outlet in fluid communication with the second conduit. The at least one balancing outlet permit the second type of fluid to exit therefrom to balance a force of ejection of the spray from the first dispensing aperture.

Abstract: A quick release clamping mechanism for securing a sleeve about a tubular structure or post where the sleeve has first and second outwardly projecting lugs that may drawn together toward one another to compress the sleeve. Each of the lugs has a bore extending therethrough and is positioned on the sleeve such that the bores are generally aligned with one another. The bore on the first lug is internally threaded. The clamping mechanism comprises an elongate bolt member receivable through the bores in the lugs. The bolt member has a first threaded end that threadably engages the threaded bore through the first lug. The clamping mechanism further comprises a tensioning member operable between an engaged and a disengaged position. When in its engaged position the tensioning member bears against the second lug and draws the first lug toward the second lug to compress the sleeve. When in its disengaged position the tensioning member releases the force drawing the first lug toward the second lug.

Abstract: A combined inlet structure and switching device for a central vacuum system includes an inlet housing having top, bottom and side walls defining a vacuum inlet chamber and a front with a dirt receiving opening. An aperture is located in the top wall and can be connected to a pipe leading to a central vacuum source. A closure member is movable between first and second positions in order to close or open the aperture. A foot operated actuator is connected to the housing and is able to pivot the closure member between the first and second positions. A spring biases the closure member towards the first position and operates when the actuator is pressed in one direction. When the closure member is moved to the second position, it will remain there unless the actuator is pressed in another, opposite direction. There is also a switch mechanism responsive to movement of the actuator for opening and closing an electrical circuit connected to the central vacuum source.
