Patent number: 6742814Abstract: A miniature patio heater is provided which has a total height of approximately 3 ft. and which has a shroud with a diameter less than 2 ft. The patio heater includes a base having a vertically extending chamber, which is approximately 1.5 ft. high, for receiving a small gas bottle. A hollow post extends upwardly from the upper end of the chamber. A heater assembly and shroud are supported at the upper end of the post. A gas line extends along the inside of the hollow post between the heater assembly and the chamber. A connector assembly provides a pivotal connection between the end of the gas line and a regulator connected to a gas bottle within the chamber. The chamber is provided with an access opening for inserting and removing the gas bottle. Thus, the gas bottle, with attached regulator, can be swung from a vertical upright position within the chamber outwardly through the access opening to an angular position to facilitate removal of an empty gas bottle and replacement with a fall gas bottle.Type: GrantFiled: March 7, 2002Date of Patent: June 1, 2004Assignee: CFM-RMC International, a division of the Vermont Castings Majestic Products CompanyInventors: Michael Resmo, Sung Boo Yoon

Patent number: 6676170Abstract: A connector includes a pivot portion (10), a sleeve (40) and a connect portion (60). The pivot portion includes a body (12) and a head (14). The body defines two channels (16), and two through holes (18) in respective communication with the channels. The head defines two outlets (20) and two bores (22). Each bore is in communication with a corresponding through hole and outlet. The sleeve surrounds the body and defines a plurality of inlets (42) in communication with the corresponding channels. The connect portion is attached under the pivot portion and engaged with a pivot axle of a manipulator. The sleeve is fixedly attached to a fixed part of the manipulator. When the combined pivot portion and the connect portion is pivoted by action of the pivot axle, the sleeve remains stationary. Pipes connected to the inlets are thereby prevented from being twisted or distorted by the manipulator.Type: GrantFiled: August 13, 2001Date of Patent: January 13, 2004Assignee: Hon Hai Precision Ind. Co., Ltd.Inventors: Vincent Ou, PuPeng Hui, Galei Hu

Patent number: 6539715Abstract: A 90° swivel connector capable of rotating 360° has threads on one end that screw into a threaded hole in a boss on a compressor portion of a turbocharger and has barbs on the other end of the swivel connector for receiving and retaining a hose. The 360° rotation enables alignment of the swivel connector with the hose to prevent kinking of the hose when the relative angular position of the connector and hose is varied to facilitate diverse engine usage.Type: GrantFiled: December 18, 2000Date of Patent: April 1, 2003Assignee: Caterpillar IncInventors: Mahmood Julazadeh, James C.

Patent number: 6517119Abstract: A retainer ring connector comprised of a ring situated between matching spokes on both the male and female members of a hose coupling. The ring is contained behind the outwardly extending spokes on the male member. When the male member is inserted into the female member, spokes on the inside of the female member pass between the spokes of the male member and are forced over the ring element which compresses sufficiently to allow the spokes to pass. After the spokes of the female member pass over the compressed ring member, the ring member expands and prevents the male and female members from disengaging and backing away from each other. The spoked retainer ring connector allows for complete rotational movement with preventing the male and female members from separating.Type: GrantFiled: March 26, 2001Date of Patent: February 11, 2003Assignee: Carrand Companies, Inc.Inventor: Paul Bruce Thomas
