The disclosures in the four applications are essentially identical and pertain to a torsion isolator having, among other features, (1) a spring disposed in a liquid pressure dampener and functioning as a piston, (2) a pivot stop associated with the spring, (3) a counterbalance associated with the spring, and (4) a control means associated with the spring for momentarily providing hydraulic slack or delay in the dampening operation. The claims in the four applications are directed to an isolator having one or more of these features. As described by the appellant, “[i]n brief, the gist[s] of the four inventions in the ‘069, ‘809, ‘835 and ‘838 applications are respectively the pivot stop D, the counterbalance C, the momentary negation of dampening or hydraulic [slack] provided 3Application 08/236,835 is the instant application, Application 08/236,809 is the subject of Appeal No. 97-2610 and Application 08/236,838 is the subject of Appeal No. 97- 2221. -3-Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
