Abstract: An adsorptive monolith made by extruding a mixture of activated carbon, a ceramic forming material, a flux material, and water, drying the extruded monolith, and firing the dried monolith at a temperature and for a time peri od sufficient to react the ceramic material together and form a ceramic matrix. The extrudable mixture may also comprise a wet binder. The monolith has a shape with at least one passage therethrough and desirably has a plurality o f passages therethrough to form a honeycomb. The monolith may be dried by vacu um drying, freeze drying, or control humidity drying. The monolith is useful fo r removing volatile organic compounds and other chemical agents such as ozone from fluid streams. Particularly useful applications include adsorptive filters for removing ozone from xerographic devices and other appropriate office machines and volatile organic compounds from automobile engine air intake systems.

Abstract: The present invention provides an antibody which catalyzes hydrolysis of .beta.-amyloid at a predetermined amide linkage. The antibody preferentially binds a transition state analog which mimics the transition state adopted by .beta.-amyloid during hydrolysis at a predetermined amide linkage. Specific antibodies provided include those which catalyze the hydrolysis at the amyloid linkages between residues 39 and 40, 40 and 41, and 41 and 42 of .beta.-amyloid. The present antibody also provides a vectorized antibody which is characterized by the ability to cross the blood brain barrier and also catalyze the hydrolysis of .beta.-amyloid. Also provided are methods for sequestering free .beta.-amyloid in the blood stream, for reducing levels of .beta.-amyloid in the brain, for reducing the level of circulating .beta.-amyloid, for preventing the formation of amyloid plaques in the rain and for disaggregating amyloid plaques. Finally, this invention also provides a method of generating antibodies by immunizing an animal with antigen comprised of an epitope which has a statine analog or which utilizes reduced peptide bond analogs to mimic the conformation of a hydrolysis transition state of a polypeptide.

Abstract: The invention relates generally to distribute computing environments and specifically to a system and a method for reducing the number of Object Request Broker (ORB) connections in an Internet Inter-ORB Protocol (IIOP) environment. Prior solutions required a n x m number of connections to handle requests from clients (82,84,86,88) to remote servers (92,94,96,98). The solution described allows there to be only m connections (81,91) through an intelligent concentrator (90), which significantly reduces requirements and allows scalability. Prior solutions did not utilize multiple intelligent master concentrator processes (90) to handle concentrator failure or dynamic scalability.

Title: Articulating stone basket
Inventor: MERCEREAU STEVE
IPC: A61B17/221
Filed: 2002-11-06
Granted: 2012-01-10
Abstract: A medical retrieval device includes a handle and a hollow sheath extending forward from the handle. A slide is attached to the handle for longitudinal movement along a path between a rearward location and a forward location. A rotary actuator having an axis of rotation generally transverse to the path of movement of the slide is mounted to the slide for rotational movement with respect thereto. A basket having at least three legs is located at a forward end of the sheath. Two adjacent basket legs are connected to a first side of the rotary actuator, and the remaining basket legs are connected to the opposite side of the rotary actuator such that rotation of the rotary actuator displaces the two legs in a first direction with respect to the sheath and displaces the remainder of the legs in a direction opposite the first direction. The basket is retracted within a forward portion of the sheath when the slide is in the rearward location, and the basket is extended forward of the forward end of the sheath when the slide is in the forward location. Thus longitudinal movement of the slide extends and retracts the basket, and rotation of the rotary actuator articulates the basket.
