Abstract: A needle shield assembly having a single-use cannula lock of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub includes a proximal end for connection to a fluid transfer device and a distal end connected to the proximal end of the needle cannula.  A collar is rotationally connected to the hub so that the collar can be rotated around the hub. An elongate needle cover removably engages the hub and covers the needle cannula. An  elongate needle shield having a proximal end and a distal end is hingedly connected, through its proximal end, to the collar. The needle shield includes two sidewalls defining a longitudinal opening and a back wall between said side walls defining a recess having an interior surface. The needle shield is capable of pivoting from an open position wherein the needle cannula is exposed, to a closed needle protecting position wherein at least part of the needle cannula is within the longitudinal opening of the needle shield. The needle shield assembly further includes structure for preventing the needle shield from pivoting into the closed position unless the needle cover is removed, and structure for locking the needle shield in the closed needle protecting position when the needle shield is pivoted into the closed position The structure for locking traps the needle cannula in the longitudinal opening of the needle shield.

Title: Device and process for thickening and conveying waste water sludges
Inventor: KUTIL JOSEF
IPC: C02F11/127
Filed: 1996-01-30
Granted: 2008-05-20
Abstract: A method is suggested for minimizing biological sludge in which biologicall y formed sludges are broken by disintegration wihtin the scope of a biological sludge treatment. The disintegrated sludge is subjected to a phase separation -- preferably a flotation - before it is fed into the biological sludge reactor, so that the treatment volume of the subsequent sludge treatment devices can be reduced. During disintegration of the biologically formed sludge, the cell walls of the microorganisms that form the organic part of the sludge are destroyed mechanically. Up to now, these microorganisms have passed the biological sludge treatment largely undamaged and form the high organic part of dry substance of up to 50% of the mass of solid substance. The broken cell components are mineralized to biogas by organisms of the biological sludge treatment, preferably under anaerobic conditions. The dry sustance of the sludge is reduced to the mineral fractions, the water binding property is reduced, whereby the outflow of free water is promoted and, thus, the sludge volume to be disposed is drastically reduced.

Abstract: This invention is a motion simulator (300) wherein the pitch, roll, and yaw axes are separated from the participant to provide a more realistic simulated motion experience in that the participant feels a translation as well as a rotation of his body as he performs a simulated climb or roll. The simulator includes a pitch boom (114) rotatable about the pitch axis and a swing boom (134), perpendicular to the pitch axis rotatable about the roll axis. The swing boom supports a participant compartment (160) which can rotate about the roll axis. The participant compartment has a center of gravity which is separated from the intersection of the pitch and roll axes. A counterweight (230) may be slidably connected to a second section (231) of the swing boom opposite the participant compartment and driven by a counterweight drive assembly (232) to achieve both static and dynamic balance. The simulator may be supported by a platform (302) which is rotatable about the yaw axis which intersects the pitch and roll axes. The passenger compartment may be raised and lowered along the yaw axis to permit ease of entry and egress of the participant to and from the passenger compartment.

Abstract: Coupling a landed helicopter to a positioning device, on a ship deck for example, has up to now been carried out by an operator in such a way that the operator manually operates grasping means (18), engaging with the longitudinal side of the helicopter, and stops it.        Methods of this type and the corresponding devices have the disadvantage that they are very time-consuming and difficult to handle.        The device according to the invention has an optical device (3o) on at least one grasping means (18) and a reflection means corresponding with said optical device and arranged on the helicopter. The optical device (30) locates the helicopter independently of its landing position and moves the grasping means (18) by means of corresponding control systems in simple fashion to the exact coupling-on position without any operator having to intervene in this process.

Title: Prosthetic graft and method for aneurysm repair
Inventor: ORTH GEOFFREY A
IPC: A61F2/07
Filed: 1996-06-05
Granted: 2007-07-10
Abstract: This invention provides a method and graft system for aneurysm repair comprising a prosthetic graft with means to draw a distal extremity of the graft over a portion of an expandable anchoring member. Pri or to deployment, the graft and the anchoring member do not overlap to reduce the outer diameter of the delivery system. Preferably, the drawing means comprises pull strands connected to the distal extremity of the graft so that the distal extremity of the graft may be pull ed over a proximal portion of the anchoring member. Subsequent expansion of the anchoring member seals the overlapped graft against the vessel wall to minimize blood flow-by and secures the graft in the vessel. Securing means may be advanced up each pull strand to abut the anchoring member and further secure the graft to the anchoring member. The graft may also comprise means to guide a second expandable anchoring member to the proximal end of the graft. Preferably, the guiding means comprise guide strands connected to a proximal extremity o f the graft. The anchoring member can then be advanced up the guide strands until the graft overlaps the second anchoring member. Expansion of the second anchoring member secures the proximal end of the graft.

Title: Improved substrates for human cytomegalovirus protease
Inventor: BONNEAU PIERRE
IPC: C07K7/06
Filed: 1997-12-23
Granted: 2004-06-22
Abstract: Human cytomegalovirus (HCMV) protease is a slow-processing enzyme in vitro.  Disclosed herein are improved fluorogenic and radiometric peptide substrates for CMV protease. The improved substrates have a typically Tbg-Tbg-Asn(NMe2) sequence replacing the Val-Val-Asn sequence, corresponding to the P4-P2 residue of the maturation site of the enzyme. The incorporation of this new sequence in a variety of substrates has afforded substrates with improved kinetic parameters compared to homologues containing the natural sequence only. For example, the substrate 2-aminobenzoyl-Tbg-Tbg-Asn(NMe2)-Ala.dwnarw.Ser-Ser-Arg-Leu-Tyr(3-NO2)ARG-OH displayed a k out/Km value of 15940 M-1, s-1 i.e. over 60-fold greater than that of the equivalent, non-optimized substrate in identical conditions. The new substrates find use in assays which can evaluate and characterize HCMV protease inhibitors having low nanomolar potency.

Abstract: A method for separating 213Bi from a solution of radionuclides wherein the solution contains a concentration of the chloride ions and hydrogen ions adjusted to allow the formation of a chloride complex. The solution is then brought into contact with an anion exchange resin, whereupon 213Bi is absorbed from the solution and adhered onto the anion exchange resin in the chloride complex. Other non-absorbing radionuclides such as 225Ra, 225Ac, and 221Fr, along with HCl are removed from the anion exchange resin with a scrub solution. The 213Bi is removed from the anion exchange resin by washing the anion exchange resin with a stripping solution free of chloride ions and with a reduced hydrogen ion concentration which breaks the chloride anionic complex, releasing the 213Bi as a cation. In a preferred embodiment of the present invention, the anion exchange resin is provided as a thin membrane, allowing for extremely rapid adherence and stripping of the 213Bi. A preferred stripping solution for purification of 213Bi for use in medical applications includes sodium acetate, pH 5.5. A protein conjugated with bifunctional chelating agents in vivo with the Na0Ac, to receive the 213Bi as it is being released from the anion exchange resin.
