Abstract: A water and inert gas fire suppression system (10), and method for extinguishing a fire in a protected space are provided with a simple and inexpensive freeze protection mechanism. To prevent the water, or other liquid fire extinguishing agent, entrained in the inert gas flow from freezing during transport through the inert gas distribution network (15, 15a, 15b, 17, 19) a secondary liquid is introduced into the inert gas flow and then removed from the inert gas flow upstream of the discharge of the two-phase water and inert gas flow into the space being protected. The inert gas is heated by means of the thermal inertia (TI) of the secondary liquid, which may be excess amount of water or an amount of another liquid having a thermal inertia (TI) at least equal to that of water.

Abstract: An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower. The pressurizing tube discharges into a liquid container thus increasing pressure within the container. An extraction tube exits the container and meets a Venturi tube that also accepts airflow discharge by the blower. A vacuum is created in the extraction tube through first and second apertures that allow fluid communication between the Venturi tube and the extraction tube. The vacuum created in the extraction tube extracts liquid from the liquid container and the liquid is drawn out of the extraction tube through the Venturi hole into the Venturi tube mixing with air flowing there through and discharging into airflow by-passing the spray adapter apparatus.

Abstract: A device is mounted between an inlet pipe and a shower head and includes a receptacle for mixing a stream of water with additives. A portion of the stream of water passing from the inlet pipe to the shower head is diverted into the receptacle. The receptacle includes replaceable containers, a first container containing a first additive and a second container containing a second additive. The diverted stream of water mixes with the first additive and the second additive upon contact with the first and second containers. The diverted stream containing additives is then returned to the main stream of water which exits the shower head. The flow of the diverted water to and from the receptacle is controlled by a valve. The present invention provides an improvement over known arrangements by providing additives which are kept separate from one another preventing a chemical reaction between the additives which would cause a loss of potency.

Abstract: Disclosed is a shower head dispenser for bath oil and the like which includes a body member with an axial bore adapted for insertion between a shower line and a shower head. The body member has two longitudinally spaced apertures or transverse bores in its side wall which communicate between the axial bore and a detachable oil container. It has a dam extending transversely across the bore. One of the apertures intercepts the axial bore at the crest of the dam, and the other aperture intercepts the axial bore upstream of the dam. The oil container has an integral valve stem thereon which seats in the end of the downstream transverse bore, and metering is achieved by rotation of the container. When water passes through the axial bore of the body member, the greater pressure at the upstream bore or aperture forces oil out of the container through the downstream bore or aperture into the axial bore at the dam, where it mixes with water enroute to the shower head.

Abstract: An improved paint spray gun assembly of the syphon type having a vented paint supply container, is characterized by a conduit connectable either between the container vent and a compressed air inlet to the gun, or between the vent and a fitting remote therefrom and open to atmosphere. With either connection, the conduit prevents dripping of paint from the vent upon manipulation of the gun by an operator, and with the connection of the vent with the compressed air a positive pressure is generated within the container to increase the paint flow rate from the gun.

Abstract: Disclosed is a shower head dispenser for bath oil and the like which includes a body member with an axial bore adapted for insertion between a shower line and a shower head. The body member has two longitudinally spaced apertures in its side wall which communicate between the bore and a detachable oil container. A plug is rotatably mounted in the bore of the body. It has an axial venturi bore therethrough, and a pair of transverse bores, one of which intercepts the axial bore at the venturi throat, and the other of which intercepts the axial bore upstream of the throat. The transverse bores of the plug are registrable with the apertures of the body upon rotation of the plug. When water passes through the venturi bore of the plug with the transverse bores aligned with the apertures, the greater pressure at the upstream bore and aperture forces oil out of the container through the downstream bore and aperture into the venturi throat, where it mixes with water enroute to the shower head.
