A high-flow liquid dispenser comprises a diluent inlet connectable to a pressurized liquid source and a backflow preventer and eductor system in fluid communication with the diluent inlet and defining a dispenser outlet for dispensing the effluent mixture. The backflow preventer and eductor system comprises at least two air gap or safe gap eductors in simultaneous fluid communication with the diluent inlet.

A mechanical piping system and method is described herein. The system includes a first pipe with a first connection element disposed on an outer surface of the first pipe. The system also includes a second pipe with a second connection element disposed on an outer surface of the second pipe. An alignment element may also be included, with the alignment element creating a sealed flow path through the first pipe and the second pipe. Also, an external collar assembly may be included. The external collar assembly may engage the first connection element and second connection element and laterally secure the first pipe relative to the second pipe.

A kit of parts is provided that can include a plurality of hose connection parts selectable from, first hose connection parts comprising one fluid inlet and one fluid outlet, second hose connection parts comprising two fluid inlets and one fluid outlet, and third hose connection parts comprising three fluid inlets and one fluid outlet. The kit of parts can be suitable for assembling a hose connection having at least a first and second fluid inlet and a fluid outlet, according to any one of three configurations. The invention also relates to a fuel dispensing unit for refueling vehicles and a method for assembly a hose connection.

A fill valve assembly for a toilet tank is described. The fill valve assembly includes a two part design. The fill valve assembly includes a fill valve that connects or engages with a shank. A connection between the fill valve and the shank is located in an interior of the tank, which is easily accessed. The fill valve may be easily replaced by disconnecting the fill valve from the shank.

A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may be a non-integral torque collar. Alternatively, the fitting may also be pulled up by turns or may have an integral torque collar. In still another embodiment, a stroke limiting member is provided that may be used to enable a fitting that is designed to be pulled up by turns to also be pulled up by torque. In other embodiments, the non-integral torque collar may be installed onto one of the fitting components, and then deformed so as to prevent or make it more difficult to remove the torque collar after installation onto the fitting component.

An apparatus for connecting two pipes in fluid communication is provided. The apparatus comprises a connector body having opposing open ends, each open end configured for receiving a free end of a pipe; a mechanical interlock arrangement, for preventing or limiting axial movement of the connector body relative to a free end of a pipe when the free end of the pipe is received in an open end of the connector body; and a mechanical seal arrangement for providing a metal-to-metal seal between a pipe inserted into one of said open ends and the connector body.

A system for performing rapid charging and evacuation of systems that contain a fluid, such as cooling systems on refrigeration products. In addition, the invention relates to methods of accomplishing rapid charging and evacuation, as well as to tools that form part of the system and that are used to accomplish the methods.

System, apparatus and method for opening a heat-bonded connection formed between two hollow, flexible thermoplastic conduits. A pressure difference is created between the inside of at least one of the conduits and the ambient atmosphere sufficient to cause expansion of a wall of the tubing conduit in the vicinity of a frangible portion at least partially blocking the connection to disrupt the frangible portion and reduce the blocking.

An apparatus comprises a first number of splines located near a first end of a first joint section and a second number of splines located near a second end of a second joint section. The first number of splines extends in an axial direction of the first joint section and spans a circumferential surface of the first joint section. Each of the first number of splines has a base, a tip, and a pair of flanks that extends from the base to the tip and forms an acute angle. Each of the first number of splines are configured to be received between adjacent pairs of splines in the second number of splines as the first end of the first joint section and the second end of the second joint section are joined.
