20100206572 | STAGE CEMENTING TOOL - A cementing tool for use in a well has a housing and a closing sleeve received thereabout. An operating sleeve is received in the housing and is interconnected with the closing sleeve so that movement in the operating sleeve will cause the closing sleeve to move. The closing sleeve is detachably connected to the housing and is movable from the first or open position to a second or closed position in which it covers cementing ports defined in the housing. The tool has a plurality of lock rings that are moved with the closing sleeve. A plurality of locking grooves are adapted to receive the lock rings such that the engagement of any of the lock rings with any of the locking grooves will prevent the closing sleeve from moving out of the closed position. | 08-19-2010 |

20130186834 | SINGLE USE SLURRYING AND CHROMATOGRAPHY SYSTEMS - Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium, such as a chromatography resin. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion during use while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration. | 07-25-2013 |
20130200005 | LARGE VOLUME DISPOSABLE ULTRAFILTRATION SYSTEMS AND METHODS - A disposable filtration system can include a disposable filter housing having an ultrafiltration filter contained therein. The disposable filtration system can further include a feed inlet and retentate outlet in fluid communication on one side of the filter and a permeate conduit on the other side of the filter for withdrawing permeate that passes through the filter. The system can include at least one disposable pressure control valve in fluid communication with either the retentate outlet or the permeate conduit and configured to regulate the pressure within the housing. | 08-08-2013 |
