Abstract: A system for selectively containing and dispensing liquids. The system has a container for the liquid with the container including a housing and a flexible diaphragm in the interior of the housing for holding the liquid. An actuator is coupled to the diaphram for moving the diaphragm between an extended position in which the diaphragm can hold more of the liquid and retracted positions in which the diaphragm holds less of the liquid than when in the extended position. A force transmitting unit is coupled to the actuator for causing the actuator to move the diaphragm in a direction from the extended position towards a completely retracted position to dispense the liquid from the container.

Abstract: A valve for dispensing fluid products includes a valve body comprised of a first portion including a first open ended passageway therethrough, and a second portion having a second passageway open at a first end and substantially closed at a second end. A port in the side wall of the second portion is disposed so that the first and second passageways are disposed in fluid communication with each other. A handle is operatively connected to the body and extends partially into the second passageway. A generally tube-like seal member is closely housed in the second passageway and is adapted to close the port for blocking fluid communication between the two passageways. The seal member is selectively shiftable by the handle between a first, normal position in blocking relation to the port and a second position in spaced relation to the port. The valve body and handle may be integrally molded with each other from a plastic material.

Abstract: The conventional potable water distribution system (310, 318) or other water supply system conventionally provided in passenger aircraft and other large passenger vehicles such as boats and trains may be modified to provide a convenient source of water under high pressure (300, 302) for fire suppression purposes. A mobile cart (10) that can be conveniently stowed inside the passenger area is provided with a source of foaming agent (132, 134), a mixing nozzle (148), and the required valves and hoses (128, 142, 150). A plurality of pressurized water outlets may be located throughout the passenger area. The cart's water inlet hose (128) is provided with a suitable quick connect/disconnect fitting (130). In order to provide the greatest versatility and effectiveness, the mixing nozzle (148) is provided with a convenient control (168) whereby the operator may choose between a heavy mist of plain water, a relatively dense foam, or a relatively light foam.
