Abstract: An underwater air valve assembly which is to be connected to an air inflatable vest worn by a diver. The air valve assembly is located within a housing, which in turn, has a depth gauge and a pressure gauge mounted thereon. The housing is connected through a flexible hose to the air inflatable vest. A separate conduit extending from the pressurized air tank worn by the diver is located within the hose. The conduit is connected through a connecting conduit to a manually operated first valve, which when operated, will cause conducting of pressurized air from the conduit into the hose and hence into the inflatable vest. A second manually operated valve is mounted within the housing and when moved to the open position causes conducting of air from the hose to the ambient. A second valve assembly can also be utilized in conjunction with an oral inflation passage for the conducting of pressurized air orally into the hose and hence into the inflatable vest.

Abstract: Provided is an underwater pressure regulator comprising a high and a low pressure chamber, an inlet to the high pressure chamber and at least one outlet port associated with the low pressure chamber. A valve assembly including a valve seat is interposed between the high and low pressure chambers to control the flow of air between the chambers. A coil spring maintains the valve in open position when pressure in the low pressure chamber decreases. An oil reservoir responds to ambient water pressure via a flexible diaphragm to maintain the outlet pressure, i.e., the secondary pressure at a constant level above the ambient pressure at different depths. A piercing member serves to perforate the diaphragm upon excessive expansion of the latter due to high pressure leakage within the regulator system, oil being discharged, under pressure, through the perforated diaphragm, whereupon the regulator then becomes a conventional water-filled unit.

Abstract: Provided is an orchard heater adapted especially to radiate heat directly to the bole and middle portions of the trees, the heater comprising an upright, generally elongated and cylindrical combustion chamber having formed therein a vertically extending looped main burner, a pilot burner disposed beneath the main burner, and a divider plate interposed between the former two burners. The burners are positioned such that the discharge orifice of the main burner lies in the plane of the axis of the combustion chamber and is oriented downwardly at the center of the divider plate. The discharge orifice of the pilot burner, in turn, is oriented upwardly to the bottom of the divider plate, the latter being apertured, typically with louvers which enable communication between the discharge orifices of the two burners. Upon ignition of liquid fuel supplied by the main burner in the chamber, the generated heat is initially radially outwardly directed by the divider plate, this heat being oriented in a horizontal plane.

Abstract: A dryer for the drying of clothing and other articles by use of a vacuum. A vacuum is applied to the internal chamber of the rotating drum by means of a swash plate which rotates simultaneously at an inclined angle with respect to the rotational axis of the drum. Suction assemblies, which include the use of one-way valve assemblies are provided between the internal chamber of the drum and the swash plate. A motor is to cause rotation of the drum which also simultaneously rotates the swash plate. The air and moisture particles from within the internal chamber of the drum are discharged into the ambient by the suction means.
