Publication number: 20080105321Abstract: A system and method for establishing plumbing kit specifications for kits containing plastic hose or tubing for installation on boats, RVs or other uses where ruler markings are imprinted longitudinally along the outside surface of stock hose. The ruler markings can be spaced approximately one inch, or other distance, and can include a series of numerals such as 1-12 or 1-11 followed by a repeat symbol. The sequence can repeat indefinitely along the length of the hose. The method allows a length specification for a particular hose segment to be generated by cutting a piece of stock hose at a particular starting ruler mark, clamping or connecting it in place, and then completing the installation of the segment by cutting the second end to the correct length and clamping or connecting it in place. The length can then be computed by reading the ruler marks on the installed hose. This information can be entered as part of the specification for a hose kit.Type: ApplicationFiled: November 2, 2006Publication date: May 8, 2008Inventors: Daniel N. Campau, Roger C. Miller

Patent number: 6443496Abstract: The present invention is directed to a connector for joining fluid flow passegeways in a fluid handling system. The connector may be manually manipulated, without using any tools, to quickly and easily couple or decouple the mating connector components. Those components include a plug having a cylindrical plug wall and a radially extending flange, and a mating socket having a cylindrical socket wall and a pair of diametrically opposed retainers. The retainers each comprise an axially extending flexible lever spaced from the socket wall. The lever is joined to the socket wall at a base or proximal end and has a latch at its free or distal end. The lever is also joined to the socket wall by a fulcrum wall or living hinge positioned intermediate the ends of the lever. A split lock ring is disposed between the socket wall and each retainer and is movable from a position adjacent the base of each retainer to a position remote from the base of each retainer.Type: GrantFiled: May 11, 2001Date of Patent: September 3, 2002Assignee: Flow-Rite Controls, Ltd.Inventor: Daniel N.

Patent number: 6311727Abstract: A valve having a port defining a first internal passageway and a body portion defining a second internal passageway. Also provided is a first aperture and an opposingly located second aperture which are in communication with the second passageway. The first aperture is adapted to permit water to flow into the livewell for recirculation and the second aperture is adapted to permit water to pump out of the livewell. A diverter is position in the location where the internal passageways merge. The diverter is moveable between first and second positions. In the first position, the diverter directs water flow through the first aperture and prevents water from flowing through the second aperture to effectuate recirculation. In the second position, the diverter directs the flow of water through the second aperture and prevents water from flowing through the first aperture to effectuate pump out of the livewell.Type: GrantFiled: September 29, 2000Date of Patent: November 6, 2001Assignee: Flow-Rite Controls, Ltd.Inventor: Daniel N.

Patent number: 6065498Abstract: A flow control device for providing variable resistance to liquid flow through a flow passageway. A cylindrical housing communicates with the passageway. The housing has a sidewall, and an inlet and an outlet each disposed at two ends. A vortex generator is located within the housing, and has a base spaced from the inlet end of the housing and an annular flow guide radially spaced from the housing sidewall. The flow guide includes a number of slots. Liquid enters the housing through the inlet and is directed outside the vortex generator and through the slots. This creates a vortex flow path within the generator as the liquid flows to the housing outlet, so that as the pressure of the liquid at the inlet increases the flow factor of the device decreases to reduce the liquid flow rate through the device at higher inlet pressures.Type: GrantFiled: February 4, 1998Date of Patent: May 23, 2000Assignee: Flow-Rite Controls, Ltd.Inventor: Daniel N. Campau
