Title: Assembly for casting and use of an isoelectric focusing strip
Inventor: PANATTONI CORY M
IPC: B29C39/26
Filed: 2003-03-04
Abstract: Isoelectric focusing gels are cast in a rod-shaped casting mold split longitudinally into two halves (11, 12), each half having a half-circle profile (22) so that the combined halves form a completed mold that is tubular in shape with a circular cross section. Flat grooves (15, 16) are cut into the flat contacting surfaces of each of the mold halves, the grooves in direct opposition to one another to form a chamber of rectangular cross section extending the full length of the mold and open at both ends. One groove receives a flexible backing strip (17) for the gel and the other serves as the casting chamber for the gel. Once the gel is cast in this mold, isoelectric focusing can be performed as if the gel were a tube gel, and the two mold halves are then readily separated to permit removal of the gel and its transfer if desired to a second dimension separation.

Title: Valve systems and method for un-heading a coke drum
Inventor: LAH RUBEN F
IPC: F16K3/20
Filed: 2004-11-19
Abstract: The present invention features a coke drum de-heading system that provid es unique advantages over prior art de-heading systems, namely the de-heading o f a coke drum without having to physically remove the head units. This is essentially accomplished using one of a variety of specially designed de-header valves that may be removably coupled to a coke drum much the same way a conventional head or flange unit would be attached. The de-header valve is equipped with, among other things, a valve closure and means for supporting a valve closure capable of forming a continuous contact seal during the coke manufacturing process. The means for supporting a de-header valve typically comprises a seat support system comprising a variety of configurational designs. Actuation of the valve closure functions to open and close the de-header valve, wherein in a closed position, the de-header valve and coke drum are prepared to receive the petroleum byproduct feed from the refinery process used to manufacture coke. Once the drum is full, the de-header valve is again actuated (opened), wherein the coke that has accumulated on the blind is sheared by the seat support system, thus effectively de-heading the coke drum and facilitating the decoking process.
