Title: Method and device for liquefaction of sediments of thickened crude oil
Inventor: STREICH BRUNO
IPC: B01F5/10
Filed: 1997-04-17
Abstract: The inventive method and the inventive device serve for liquefaction of sludgy to compact sediments (3) in vessels (1) in which crude oil (2) is stored and/or transported, whereby a liquid is injected above the sediment surface via nozzles (11) under the effect of which liquid the sediment (3) is at least partly liquefied or dissolved in the liquid such that it can be removed from the vessel (1) together with the liquid. For this purpose a substantially horizontally flowing liquid current which is possibly closed in itself is created above the sediment surface by directing the injection through all nozzles (11) such that the injection direction has a horizontal component which is orientated tangentially to a current line of the liquid current to be created and is orientated in flowing direction. The injected liquid is crude oil or a refinery product and differs from the lowest levels above the sediment in that it comprises a smaller share of heavy components.

Inventor: MUNRO CINDY L
IPC: A61K39/00
Filed: 1997-06-20
Abstract: FimA proteins from streptococci and enterococci, which are responsible for bacterial adherence to damaged heart tissue, are potent vaccines against a patient developing endocarditis. Recombinantly produced FimA proteins from S.  parasanguis provide protection against S. parasanguis derived endocarditis, as well as endocarditis derived from several other streptococci. Conserved DNA  regions in viridans streptococci and enterococci suggest that FimA from these strains will be broadly applicable as a vaccine.

IPC: H03H9/24
Filed: 1997-11-13
Abstract: A multi-material resonant thin film beam for a micromechanical sensor having a zero temperature coefficient of frequency (TCF) which is the resonant frequency shift with temperature change. One of the materials may be polysilicon and the other material may be silicon nitride or silicon oxide. Each material has a different thermal coefficient of expansion. The proportion of the various materials is adjusted and the specific geometries are determined so that the TCF is zero.  One embodiment is a microbeam composed of two polysilicon thin films with a silicon nitride thin film inserted between the polysilicon films. The thickness of the silicon nitride film may be adjusted to trim the TCF to zero. The film of nitride instead may be placed on one side of a polysilicon film to form a beam. Dual or multiple beam resonators likewise may be made with several materials. The nitride may be placed in the shank areas which join and secure the ends of the beams. Such zero TCF beams may be incorporated in microsensor structures for measuring pressure, temperature, strain and other parameters.

Title: Resorbable interposition arthroplasty implant
Inventor: BERMAN ANDREW B
IPC: A61F2/30
Filed: 1998-04-17
Abstract: A resorbable implant (41) for interposition arthroplasty which is intended to fill a void between two adjacent bone ends, providing a cushion between the bone ends to prevent impingement of the bone ends while providing time for tissue to infiltrate into the space occupied by the implant (41). It has a protracted resorption time of preferably at least three months to allow time for the proliferation of load-bearing host fibrous tissue in place of the resorbed implant material. The implant (41) preferably is porous with a pore size of greater than about 80 microns in order to enhance infiltration of fibrous tissue. The implant (41) has a modulus in the range of 0.8 to 20 MPa which is soft enough to allow it to conform to surface irregularities of the adjacent bone surfaces while being hard enough to maintain a desired separation between those bones (13, 15, 17, 19) while tissue infiltration replaces the resorbable implant material. The implant (41) may be preformed to the desired shape or alternatively may be formable by the surgeon by methods such as carving with a scalpel. A preferred application for the implant is as a trapezium bone (11) replacement.
