A preferred embodiment has a fan-like sprinkling pattern, the jets of the fan being symmetrically or asymmetrically brought together or moved apart. The fan edges can be adjusted independently of one another.

Abstract: The tube closure comprises a cap and a nut which work in concert with each other to effectively seal a nipple at the end of a threaded tube or pipe and which facilitate removal of the cap. The cap has a flared end portion, a narrowed neck portion, a head portion, and an inner cylindrical sealing surface which engages the nipple. The cap is removably engaged within the nut with the nut at the neck portion, and is sealingly engaged on a cylindrical surface of the nipple. The cap may be removed from the nut by withdrawing the head through the nut, with an axial separation force. Removal of the cap from the nipple requires an axial cap removal force. The required axial separation force is greater than the cap removal force. The engagement of the cap within the nut allows the unscrewing of the nut to provide an axial force on the cap to disengage the cap from the nipple without separating the nut from the cap.

Abstract: The present invention is a rock dusting apparatus comprising of a pressure-sealable tank, an air distributor and a means of supplying a source of pressurized air. The air distributor is positioned inside the tank. Rock dust is then placed inside the tank which is then sealed. Air is introduced into the tank through the air distributor which includes a plurality of orifices through which the air passes. The air then mixes with, dries and suspends the rock dust particles. The air stream carrying the entrained rock dust particles exits the tank through an outlet opening thereby distributing the rock dust as required.

Abstract: A vehicle wash boom apparatus includes a fixed journalling tube for journalling a boom-supporting tube for reciprocal and rotational movement about a vertical axis. The journalling tube carries a cam and the boom-supporting tube carries a cam follower. A pair of torsion springs at all times bias the cam follower in an upward direction against a cam surface of the cam which is inclined relative to the vertical axis. Thus, as the boom is rotated, the interaction between the cam and the cam follower effects a vertical movement of the boom-supporting member which allows the boom while being used to by-pass a like boom of an identical apparatus when in its home or parked position.

Abstract: A process of filling an underground natural gas pipeline and similar pipelines with an inert foam to render the pipeline unusable. Pipelines which are no longer in service must be properly be abandoned in a manner acceptable to the United States Environmental Protection Agency. The pipeline is cut at periodic intervals to create a shorter pipe and small sections of pipe are removed. An electrical or plumber's snake or similar device is passed through the pipe between the cuts to ensure that a clear path exists. A dual hose is then pulled through the pipe from a first opening to a second opening and a mixing device having a mixing head and a static mixing tube is then attached to the hoses. The chemicals needed to produce the foam are then pumped through the hoses. The hoses are then pulled back to the first opening as the mixed chemicals are pumped through the mixing head. The mixed chemicals react with each other to create an inert foam.

Abstract: The injector comprises a duct (31) through which a liquid fuel which forms a film lining its wall, and an atomizing fluid, are transmitted to its downstream part, from where the fuel is sprayed, forming a mist with the atomizing fluid.The downstream part has, from the duct (31) towards the free end of the injector, a chamber (32) for destabilizing the film which has a cross section that is larger than that of the duct, a throat (33) for detaching the film extending the destabilization chamber and having a cross section that is smaller than that of this chamber, and a spray orifice (34) which is open at the end of the injector, into which the throat opens, and which has a larger cross section.Use: heating furnaces, especially glass furnaces.

Abstract: A freezeless yard hydrant comprises a single length, electrically heated, hydrant apparatus that does not have an underground drain port. The operating mechanisms are located in the outlet head, above ground, to facilitate the assembly, operation and repair of the hydrant. A single length heater is provided to prevent the hydrant and the water supply connection from freezing under the coldest environmental conditions expected where this type of hydrant would be used. Heat conduction through the water directly from the heating element and the casing materials permits a single length hydrant and heater to be used. By using the electric heater to prevent the freezing, the water does not have to be drained out of the hydrant. The use of such a heater also makes the hydrant very simple to construct and operate. No cumbersome reservoirs or expulsion apparatus are needed to draw water out of the hydrant. This results in an efficient and relatively inexpensive mechanism.

Abstract: A spray paint gun air stabilizing structure comprised in sequence of a connector, a valve, a shouldered tube, a spring and a piston. Wherein, the shouldered tube is provided inside the connector to accommodate the valve. A proper gap exists between the valve and the connector. The spring slips on the hollow piston. One end of the piston and its walls form two stopper walls compromising the inner diameter of the air passage of the spray paint gun while the other end of the piston penetrates through the shouldered tube towards the valve. Whereby, the pre-pressurized air in normal status drives the valve in the connector, then is introduced into the spray paint gun via the gap provided to the inner wall of the valve. If the air is over-pressurized, back-pressure is formed in the air passage to push the piston to compress the spring, the outer end of the piston gets closer to the end surface of the valve to narrow down the gap.
