Title: Metathesis unit pretreatment process with formation of octene
Inventor: KRUPA STEVEN L
IPC: C07C6/04
Filed: 2008-11-17
Abstract: Disclosed is a process for integrating a butene dimerization process with a metathesis process to remove isobutene from the feed stream to the metathesis reactor. The isobutene is preferentially dimerized in the dimerization process to leave n-butenes for metathesis with ethylene. An upstream selective hydrogenation process also isomerizes 1-butenes to 2-butenes which is the preferred butene reagent in the metathesis process. A common frac-tionator column for the dimerization and hydrogenation processes is also described.

Title: Compact quick coupling mechanism for tool attachment
Inventor: STOLLERY RANDAL D
IPC: E02F3/96
Filed: 2012-03-14
Abstract: A compact quick coupling apparatus has a wedge movable between closed and open positions. A wedge spring extends in the opening direction from the wedge and urges the wedge in the closing direction. A latch spring urges a safety latch to a latched position to prevent the wedge from moving. A single acting hydraulic cylinder extends through the wedge and extends in the opening direction from the wedge. As the hydraulic cylinder extends it first moves the safety latch to the unlatched position, and then moves the wedge in the opening direction. When pressurized fluid is released from the hydraulic cylinder, it retracts and the wedge moves in the closing in response to the wedge spring until the wedge reaches the closed position, and then the hydraulic cylinder further retracts in response to the latch spring and the safety latch moves to the latched position.
