Title: Method and device for joining screens
Inventor: HASSALL CASPAR
IPC: B01D33/03
Filed: 2002-07-16
Abstract: A screen is described wherein one end of the screen frame is provided with an upwardly open channel profile and the other end with a similar but downwardly open channel profile, such that the outboard edge of an upwardly open profile will fit within the channel of a downwardly open profile provided along the edge of an adjoining screen frame, to enable two such screens to be connected together and to enable linear movement in a direction generally perpendicular to the line of engagement and generally in the plane of at least one of the two screens, to be transmitted from one screen frame to the other. The engagement of one profile by another also serves to close the gap between the two screen frames and prevent at least particulate material from passing therebetween.  Preferably the engagement prevents liquid from passing therebetween. The engagement may comprise a lost motion connection so as to permit one frame to be hingeable relative to the other about the connection, but still provides a reliable force-transmitting connection to enable a rear screen frame to be removed from the support structure simply by pulling out the front frame of the pair.

Inventor: ABERIN CHERYL S
IPC: B01J20/281
Filed: 2002-05-15
Abstract: Plasmid DNA is purified from a cell lysate by acidifying the lysate with a combination of a mineral acid and an inorganic salt in place of the commonly used acetate buffer, allowing chromosomal DNA and other impurities to precipitate out and recovering the supernatant, and applying the supernatant directly to a hydroxyapatite chromatographic separation medium. The use of the mineral acid and organic salt avoids the degradation of the hydroxyapatite that frequently accompanies repeated use with acetate and related compounds.

Abstract: A modified alkali silicate composition for forming an inorganic network matrix. The modified alkali silicate matrix is made by reacting an alkali silicate (or its precursors such as an alkali hydroxide, a SiO2 source and water), an acidic inorganic composition, such as a reactive acidic glass, water and optional fillers, additives and processing aids. An inorganic matr ix composite can be prepared by applying a slurry of the modified aqueous alkal i silicate composition to a reinforcing medium and applying the temperature an d pressure necessary to consolidate the desired form. The composite can be shaped by compression molding as well as other known fabrication methods. A notable aspect of the invention is that, although composite and neat resin components prepared from the invention can exhibit excellent dimensional stability to 1000~C and higher, they can be prepared at the lower temperatur es and pressures typical to organic polymer processing.

Title: Apparatus and method for urging fluid into a pressurized system
Inventor: RESUTEK JIM
IPC: F25B45/00
Filed: 2001-11-27
Abstract: The present invention generally relates to an apparatus and method for urging fluid from a charging system to a pressurized system. The apparatus (20) has a rigid body (90) with a conduit (68) defined therein. The body (90) is mounted between, and connected to, a charging system (24) containing pressurized fluid (22) and a pressurized system (26). When the body (90) is connected to both the charging system (24) and the pressurized system (26), a force may be applied on the charging system (24) toward the pressurized system (26). The force causes the charging system (24) and the pressurized system (26) to mate with the body (90). The mating of the body (90) to the charging system (24) and the pressurized system (26) urges a discharge tube (56) of the charging system (24) to retract, thereby actuating a first valve (60), operatively connected thereto, to release fluid into the conduit (68), and urges a pin (162) of the pressurized system (26) to retract. The retraction of the pin (162) actuates a second valve (160), opratively connected to the pin, to permit the fluid (22) in the conduit to enter the pressrized system (26).
