Abstract: Apparatus for metering a predetermined timed volume of fluidic material through a dispensing circuit upon activation of a trigger, where the trigger actuates an air valve which is connected to a second time-controlled air valve. The second air valve delivers a predetermined timed shot of pressurized air to an air cylinder which is mechanically coupled to the fluidic material dispensing circuit.

Abstract: This application discloses "wiping" of a liquid, molten zinc, for example, across the surface of a strip to which it adheres. A wiping fluid, such as steam, is directed from an orifice at the strip. A valve, preferably an elongated relieved bar is positioned adjacent and behind the orifice, and flow of wiping fluid is controlled by rotation of an elongated valve in the form of a relieved bar or cam.

Abstract: Apparatus including the combination of a nozzle adapted for connection to a source of fluid under pressure and having a port for discharging a jet fluid axially of the port and a wall mounted in spaced relation to the port and generally across its axis and having an opening dimensioned for passage therethrough of the jet when the port and wall opening are in registration, and wherein the wall and nozzle are mounted for relative displacement for moving the port and opening into and out of registration; and manually engageable means for effecting such relative displacement. Additionally a housing is provided around the nozzle to form a relatively enlarged, reduced pressure, fluid collection chamber for fluid deflected by the wall in the misaligned "shutoff" position of the device.

Abstract: An improved sprinkler for a fire protection sprinkler system in which the sprinkler opens to discharge water at one temperature and closes to stop the flow of water at a lower temperature. A pilot valve is actuated by a bimetal disc which also resiliently biases the pilot valve in a closed position. The bimetal disc has a snap action resulting in better control of the "on" and "off" temperatures of the sprinkler. A thermal delay for closing is obtained by the hysteresis which is designed into the bimetal disc.
