Abstract: ABSTRACT            This invention relates to an improvement in a process for the separation of a multi-component stream comprising component A, B and C with A being the most volatile and C the least volatile.  A multi-component feed is introduced to a multicolumn distillation system comprising a first or main distillation column and a side column wherein at least a light component A is separated from a heavier component C in the main distilla-tion column, the lighter component A being removed as an overhead fraction and the heavier component C being removed as a bottoms fraction.  The improvement for enhanced recovery of component B in the side column comprises withdrawing a liquid fraction from the main distil'lation column at a point intermediate the overhead and feed and introducing that liquid fraction to an upper portion of the side column.  Lighter components are withdrawn as an overhead from the side column and returned to an optimal location in the distillation system, typically the main distillation column.  A vapor fraction is also withdrawn from the main distillation column at a point intermediate the bottoms and feed and vapor fraction is introduced to a lower portion of the side column.  A liquid fraction is withdrawn as bottoms  and returned to the main distillation column. Thermal integration in the side column Is effected by removing a portion of the liquid typically from the stripping section of the side column and vaporizing this fraction against a vapor fraction obtained from the main distillation column.  At least a portion of the vaporized liquid from the side column is returned to the multi-column distillation system.  At least a portion of the vapor fraction from the main distillation column is condensed and liquid is returned to an optimal point in the multi-column distillation system.  Thermal integration may also be achieved by with-drawing a vapor fraction from the rectifying section of the side column and heat exchanging with a liquid fraction from the main distillation column.

Title: Swing plate latch mechanism
Inventor: OLIVIER ANDRE W
IPC: G01V1/20
Filed: 1993-06-25
Abstract: For confidently coupling towed external devices to a marine seismic cable, a latch mechanism having a novel swing plate to improve the adjustability of the mechanism and provide a positive, clearly visible indication of latched and unlatched conditions.          The swing plate serves as an external linkage between a rotatable adjustment head for a locking pin and a translatable lever arm for a locking rod.  The locking pin and the locking rod extend from a latch housing on a towed device, such as a cable-leveling bird, and engage with a keyhole slot in a locking collar on the streamer.          The swing plate engages the adjusting head, which protrudes from a side of the housing,  in a push-nut engagement.   Shoulders positioned approximately radially opposite each other on the swing plate push against the lever arm, which also protrudes from the side  of  the  housing,  as  the  adjustment  head  is  rotated  to completely extend or retract the locking rod into the mating slot, thereby locking or unlocking the mechanism as the lever arm is jammed to the top or the bottom of a guide slot. As the adjustment head is rotated to force the lever arm to the top or the bottom of the guide slot, a positive stop, which is clearly evident to an operator performing the adjustment, is provided.  The structure of the swing plate, such as structure along a radial sector of the swing plate between the shoulders, is also used to occlude and reveal clearly visible indicia of a locked or unlocked mechanism as the swing plate is rotated.

Title: Valve with actuator
Inventor: BUSHNELL RAYMOND B
IPC: F16K/
Filed: 1994-03-08
Abstract: VALVE WITH ACTUATOR     Abstract A valve with actuator is disclosed with the valve con-trolled by a piston responsive to in line fluid pressure during opening and closing movement.  The actuator shifts a valve stem to open a poppet valve in the piston to admit in line pressure into a chamber to act on rearward surfaces of the piston to advance  the piston for valve closing.  Closing movement of the piston is started by the actuator and continued by in line fluid pressure.  A valve on the stem controls communication of the chamber, in which the piston is carried, with an outlet to close the chamber for pressurization effect causing forward seating of the piston.  Valve opening movement of the actuator closes the piston mounted poppet valve and vents the chamber allowing in line fluid pressure to shift the piston rearwardly to an open position.  Another form of the valve with actuator includes a housing defining lengthwise passageways communicating an inlet with an outlet.

Title: Process for producing water absorbent resin
Inventor: DATE MASASHI
IPC: B01J20/26
Filed: 1994-03-09
Abstract: ABSTRACT      The present invention relates to a process for producing water absorbent resin comprising a step of adding a high-molecular crosslinking agent which has at least 2 azetidinium salt groups in the molecule and has at least 1000 weight-average molecular weight to the water absorbent resin paticles having carboxylic groups and carboxylic acid salt groups and a step of efficiently crosslinking the vicinity of the surface of the water absorbent resin particles.  In the process for producing water absorbent resin according to the present invention, the use of high-molecular crosslinking agent achieves less permeation of the crosslinking agent into the water absorbent resin particles and enables efficient crosslinking of the vicinitiy of the surface of the water absorbent resin particles.  Consequently, the water absorbent resin having high water absorbency both under pressure-free state and under loading can be manufactured.          Because the crosslinking agent contains a large amount of azetidinium salt groups highly reactive to carboxylic acid groups or carboxylic acid salt groups in the molecule, the water absorbent resin having high crosslinking efficiency, good safety, and good flowability can be manufactured.
