Abstract:
A liquid chromatography system including a liquid pump having a pumping chamber, an inlet port, an outlet port, and a purge port, all communicating with the pumping chamber; a separation column; an outlet valve connected between the outlet port and the separation column and adapted to control liquid flow therebetween; a source of mobile phase; an inlet valve connected between the inlet port and the source and adapted to control liquid flow therebetween; and a purge valve connected to the purge port.

Abstract:
A mechanical coupling including a drive shaft reciprocable on an axis; an actuator shaft mounted for reciprocating rectilinear motion on the axis; and a coupling mechanism for transmitting reciprocating motion of the drive shaft to the actuator shaft; the coupling mechanism including a pivot joint allowing relative pivotal movement between the drive shaft and the actuator shaft, and a translational joint allowing relative translational movement between the drive shaft and the actuator shaft in directions transverse to the axis, the translational joint having a flexible link connecting the pivot joint and the drive shaft.
The boatcrashed March 12 into a stationary barge that was part of the Tappan Zee Bridge construction project, killing three crewmembers. Two of the victims, 29-year-old Timothy Conklin and 62-year-old Paul Amon, were pulled from the river the day after the crash.
