Patent number: 8820069Abstract: This disclosure describes an apparatus having a valve and an elongated shape memory alloy element. The valve has a lever in a first position, whereby the valve is closed. The elongated shape memory alloy element has a first end connected to the lever. The shape memory alloy element has been strained to have a first length, wherein exposure of at least a portion of the shape memory alloy element to a temperature at or exceeding its austenite transformation temperature causes the shape memory alloy element to shorten to a second length, the second length being less than the first length, thereby causing the first end of the shape memory alloy element to pull the lever to a second position, whereby the valve is opened.Type: GrantFiled: March 3, 2010Date of Patent: September 2, 2014Assignee: Hexagon Technology ASInventors: John D.

Patent number: 5180490Abstract: An oil filter assembly for an internal combustion engine includes a filter element disposed in a spin-on canister which is detachably secure to a mounting adaptor having a conduit normally permitting some of the filtered lubricating oil to bypass the main lubricating circuit of the engine. The filter element carries a plug which seals the bypass conduit when the canister is installed on the adaptor so as to disable the internal bypass circuit of the adaptor and force all of the filtered oil to flow to the main lubricating circuit.Type: GrantFiled: January 31, 1992Date of Patent: January 19, 1993Assignee: Baldwin Filters, Inc.Inventors: John A.
