Abstract: A gas supply method includes controlling communication between first and second gas pipes and a diffusion chamber using first and second valves; controlling discharge of gas within the first and second gas pipes using third and fourth valves connected upstream from the first and second valves; and controlling communication between an exhaust pipe and the diffusion chamber using a fifth valve. The gas supply method further includes a first pressurization step of closing the first valve and the third valve before starting a first step and pressurizing a first gas within the first gas pipe; a second pressurization step of closing the second valve and the fourth valve before starting a second step and pressurizing a second gas within the second gas pipe; and an exhaust step of opening the fifth valve upon starting the first step and the second step, and discharging gas within the diffusion chamber.

Abstract: A soiled surface cleaning system is described for pre spraying soiled surface areas, and for rinsing and extracting the pre sprayed soiled surface areas, wherein the pre spraying of the soiled surface areas does not have to be stopped in order to perform the rinsing and extracting of the pre sprayed soiled surface areas.

Abstract: A method and system of providing a mist in a grocery display that injects biocidal solution into a misting line of water during a phase of the misting cycle.

Abstract: A hybrid foam system for providing a variety of proportioned foam solutions is provided. The system includes a low flow foam proportioning system operatively associated with a high flow foam proportioning system and a system controller for controlling the operating conditions of the overall hybrid foam system.

Abstract: A system and method are provided for selectively containing and dispensing a predetermined liquid material in and from a source container in failsafe manner, wherein a housing is disposed to receive a pressurized fluid stream, and a selectively operable valve assembly is disposed in a flow path defined in the housing. The housing includes an inlet, an outlet, and an intermediate portion extending therebetween, which is formed with an admission port for admitting the predetermined liquid material. The valve assembly is disposed between the housing's inlet and outlet, and may be selectively operated to alternatively open and close access of the predetermined liquid material into the housing. The valve assembly is operably actuated responsive at least in part to the pressurized fluid stream in the flow path, whereby admission of the predetermined liquid material into said housing is keyed by introduction of the pressurized fluid stream into the flow path.

Abstract: A sprayable polymeric material and a process for preparing the material which contains a fibrous material, dispersed throughout the polymeric material. A restriction free spray nozzle is provided for mixing and spraying the polymeric material having a fibrous material, the nozzle having a restriction free check valve. A reinforced structure, and a method of making the structure are provided, the structure having layers of the polymeric material (both film and foam) containing the fibrous material. A flexible liner is provided of a porous geotextile fabric and a polyurethane composition comprising the fibrous material sprayed over the geotextile fabric.

Abstract: An aerosol spray gun used selectively in two spraying modes of small and large patterns is provided. The aerosol spray gun has a throttle valve, an air duct, and a coupling link. The throttle valve has an internal air duct for supplying pressurized air to a patterning air outlet which shapes a paint spraying stream jetted out from the aerosol spray gun, and has a movable valve element to which a compressed spring applies force to open the valve. The air duct created at the tip of the movable valve element supplies a small volume of air from the internal air duct to the patterning air outlet while the movable valve element seats on a valve seat. The coupling link, coupling the movable valve element to the trigger, has an elongated hole to disconnect the trigger from the movable valve element without cooperative relation between them from an initial stage where an operator begins to squeeze the trigger to an intermediate stage before the operator fully squeezes the trigger.

Abstract: A fuel injector for an internal combustion engine includes a first injection valve having a first valve element that can be displaced in an axial direction and a first actuating device located axially downstream from the first injection valve to actuate the first injection valve. The fuel injector also has at least one second injection valve with a valve element that can be axially displaced and a second actuating device to actuate the second injection valve. The second actuating device is mounted axially downstream from the first actuating device in the valve housing, and the second actuating device to actuate the second injection valve is coupled to the latter by an actuating element, in the form of a cage-like arrangement, mounted in the valve housing in such a way that it can be displaced axially and bypasses the first actuating device.

Abstract: A chemical foaming system for use in a floor cleaning machine has a foam generator and a delivery system upstream of the foam generator in communication with a source of pressurized fluid and a source of liquid cleaning solution. The delivery system delivers pressurized fluid and liquid cleaning solution to the foam generator. A dispensing system is disposed downstream of the foam generator for dispensing foam generated by the foam generator onto the floor being cleaned. The foam generator has a pair of independent foaming chambers in generally parallel flow relationship intermediate the delivery system and the dispensing system whereby a portion of pressurized fluid and liquid cleaning solution delivered to the foam generator by the delivery system flows into one of the foaming chambers. The remaining portion of the pressurized fluid and liquid cleaning solution delivered to the foam generator flows into the other foaming chamber.
