Patent number: 8616251Abstract: A cup for draining residual fuel from a breakaway hose coupling. The cup features a substantially cylindrical rigid stem extending upward from the floor of the cup reservoir, said stem featuring a cavity for receiving the pin of a breakaway hose valve. When the stem is pressed against the valve pin, the valve is opened, relieving pressure within the hose and releasing residual fuel within the hose. The residual fuel drains directly from the hose into the cup, facilitating safe and convenient disposal of the fuel, which may be poured using an integral pour spout in the cup rim.Type: GrantFiled: November 9, 2010Date of Patent: December 31, 2013Assignee: Husky CorporationInventors: Grenville G. Sutcliffe, John C. Sever

Patent number: 7000651Abstract: A fuel storage tank vapor cooler to effect pressure reduction, in a fuel dispensing system, including the application of a refrigeration unit, that operates under the effects of a control unit, sensitive to vapor pressures, and vapor flow, to initiate the operations of the refrigeration unit, and effecting, through a properly located heat exchanger, a reduction in the temperature of the stored vapors, and thereby reducing its incident pressure. Such heat exchangers may be located either within the vapor storage area of the underground storage tank, the heat exchanger may locate in cooperation with the vapor return line, to the underground storage tank, or it may be located within the vent line from the storage tank, to chill the vapors and thereby provide for a reduction in their pressure. Such heat exchangers may be used in combination, or individually, whatever is determined to obtain the results as desired from the system of this invention.Type: GrantFiled: July 11, 2003Date of Patent: February 21, 2006Assignee: Husky CorporationInventors: Arthur C. Fink, Jr., Grenville G. Sutcliffe

Patent number: 4615547Abstract: A multi-plane swivel connector for use in attaching a pair of fluid conveying members together, the connector including a pair of swivel portions, that connect together at proximate ends, one end being insertable within the other, a double sealed connection provided at the junction of the connection of the swivel ends together, there being a swivel nut securing externally to the outer end of one of the pair of swivel portions, there being a double sealed connection provided between the said swivel nut and the said contiguous swivel portion, there being a pair of O-rings provided at each of the double sealed connections between the swivel portions, and the connection of the swivel nut to one of these swivel portions, said pair of O-rings at each double sealed connection being of step relationship with one O-ring being of greater diameter than the other O-ring, one of the O-rings being formed of fluoro carbon, while the other O-ring of each double sealed connection being formed of fluoro silicone; and during thType: GrantFiled: November 24, 1982Date of Patent: October 7, 1986Assignee: Husky CorporationInventors: Grenville G. Sutcliffe, Arthur C. Fink, Jr.

Patent number: 4331190Abstract: In a bracket for use in conjunction with a fuel dispensing nozzle, said bracket mounting to the nozzle at the location of the joint between the nozzle and its spout, the upper portion of said bracket extending upwardly and outwardly and formed into a hook arrangement, for securing through the nozzle holster that supports the same during nonusage, while the lower portion of the bracket extends downwardly and is integrally bent for connection with the nozzle, thereby assuring a guide that automatically requires shut off of the fuel pump when the nozzle is inserted into its holster as during nonuse.Type: GrantFiled: March 19, 1980Date of Patent: May 25, 1982Assignee: Ausley CorporationInventors: Grenville G. Sutcliffe, Ronald F. Bradley, Paul D. Mercer

Patent number: 4103936Abstract: The invention provides a fluid tight coupling for securing the spout of fuel dispensing nozzles to the nozzle body and utilizes a metallic annular gland mounted on the upstream end of the spout and positioned thereon by the engagement of a knurled band on the spout with its inner surface by mechanical expansion of the spout, the gland being outwardly shaped and positioned on the spout to be tightly engaged and compressed between tapered surfaces and the body outlet nipple rim and the spout securing clamp nut, with the downstream portion of the gland compressed thereby into tight sealing engagement with a smooth surface portion of the spout to effect a tight fluid seal.Type: GrantFiled: February 14, 1977Date of Patent: August 1, 1978Assignee: Husky CorporationInventors: Grenville G. Sutcliffe, Roy F. Washausen, William L. Tomes, Herman Ray Gould
