Patent number: 4938254Abstract: An over-pressure relief valve to be positioned within an opening of a vessel, the relief valve having a valve member with a closed end which is positioned within the opening and which carries an O-ring adjacent to the closed end. The O-ring normally engages the vessel in a circumferential pattern surrounding the opening to seal the opening. The valve member further has a second end within the vessel and the second end is resiliently biased toward the interior of the vessel by a coil spring. The coil spring is trapped between a radial flange of the valve member, which is positioned at the second end thereof, and the inside of the vessel. An over-pressure condition within the vessel overcomes the effect of the coil spring and moves the valve member to break the sealing engagement between the O-ring and the vessel. An initial, limited degree of venting occurs through an annulus which is formed between the opening and the valve member.Type: GrantFiled: September 21, 1989Date of Patent: July 3, 1990Assignee: Borg-Warner Automotive Electronic & Mechanical SystemsInventor: David R. Gimby

Patent number: 4853832Abstract: A converter for converting a low voltage direct current power source to a higher voltage, high frequency alternating current output for use in an electrical system where it is desired to use low weight cables and other circuit elements. The converter has a first stage series resonant (Schwarz) converter which converts the direct current power source to an alternating current by means of switching elements that are operated by a variable frequency voltage regulator, a transformer to step up the voltage of the alternating current, and a rectifier bridge to convert the alternating current to a direct current first stage output. The converter further has a second stage series resonant (Schwarz) converter which is connected in series to the first stage converter to receive its direct current output and convert it to a second stage high frequency alternating current output by means of switching elements that are operated by a fixed frequency oscillator.Type: GrantFiled: August 1, 1988Date of Patent: August 1, 1989Assignee: University of ToledoInventor: Thomas A.
