The units are adjustably secured together by a pivot coupling having a pivot axis extending transverse to the groove axis for pivotal adjustment of the orientation of the second connector unit relative to the first connector unit, whereby the relative orientation of the first and second pipes to be coupled can be adjusted. A releasable locking device releasably secures the second connector unit at a selected orientation relative to the first connector unit.Type: ApplicationFiled: December 5, 2000Publication date: June 6, 2002Inventor: Jan Prochac

Patent number: 6386430Abstract: In a system and method for adjusting a height of a base of a clamp to fit to strips of a plurality of IC (integrated circuit) package sizes, the clamp is comprised of a fixed clamp portion and the base having a height that is adjustable with respect to the fixed clamp portion. A bar is disposed over the base of the clamp along a length of the base of the clamp, and the bar is fixed with respect to the fixed clamp portion. Each of a plurality of dummy strips of IC packages corresponds to a respective IC package size. A respective dummy strip of IC packages corresponding to a respective IC package size is placed on the base of the clamp to be supported by the base of the clamp. In addition, a plurality of height adjustment jigs are disposed on the bar to slide along the bar. Each of the height adjustment jigs has a respective size corresponding to a strip of a respective IC package size.Type: GrantFiled: September 14, 2000Date of Patent: May 14, 2002Assignee: Advanced Micro Devices, Inc.Inventors: Wanus Prommate, Narong Bokkaew, Grid Kachane
