Patent CA-2184645-A1 (CA)
Inventor: MACNAUGHTON DOUGLAS J
IPC: B07B1/00
Filed: 1996-09-03
Abstract: A portable vibrating screen comprising an arched frame, a basket supported on top of the arched frame by springs and a rotatable eccentric shaft for impartinga reciprocal movement to the basket. The arched frame has a vertical tall end, a vertical short end and two spaced apart stringer members joining the upper portions of the tall and short ends. The stringer members define an inclined plane between the tall end and the short end. The tall end has a first pair of spaced apart leg members and a first ballast mounted between the leg members of that first pair. The short end has a second pair of leg members and a second ballast mounted between the leg members of that second pair. An amplitude of a vibration of the basket transmitted to the arched frame is largely absorbedby the mass of the first and second ballasts. In another aspect of the present invention, the eccentric shaft has bearings attached to the basket and to the stringer members for retaining the basket along the inclined plane. The stringer members are flexible, within an elastic limit thereof, a sag distance corresponding to at least an offset dimension of the offset shaft. When the basket is filled with a load of screenable material which is larger than a normal load, the eccentric movement of the shaft is partly or entirely absorbed by the deflection of the stringer members.

Title: Blood gas probe
Inventor: PONTZER STEPHEN A
IPC: A61B5/145
Filed: 1995-03-22
Abstract: A blood gas monitoring system monitors blood gas from blood in a blood vessel (36). A blood probe (10) is introduced into the blood vessel (36). The blood probe (10) includes a probe body (16) defining a probe chamber and a first gas permeable membrane (12) coupled to a first end of the probe body (16). A sensor (25) is provided proximate a second end of the probe chamber to sense a desired characteristic of the blood gas. Blood gas is allowed to diffuse across the first gas permeable membrane (12) and into the probe chamber so that the blood gas in the probe chamber is substantially in equilibrium with the blood gas in the blood vessel (36). Once blood gas in the probe chamber has substantially equilibrated with the blood gas in the blood vessel (36), the desired characteristic of the blood gas is sensed.

Abstract: A method for maintaining the position of a containment boom in a fast flowing waterway.   Firstly,  providing an elongate containment boom having a first side, a second side, a first end,  a second end and a longitudinal axis.   The containment  boom  consists  of  a  plurality  of  smaller substantially coaxial boom sections.  Secondly, providing a plurality of floats having floating deflector appendages. Thirdly, placing the plurality of floats at spaced intervals along the containment boom between the boom sections, with the floating deflector appendage of each float oriented on the first side of the containment boom extending outwardly at an angle  in relation to the  longitudinal  axis and pointing generally toward the second end.  Fourthly, positioning the containment boom in a fast flowing waterway with the second end anchored adjacent the shore and releasing the first end of the containment boom into the fast flowing waterway such that fast flowing water passing along the second side of the containment boom causes the first end of the containment boom to swing into the fast moving waterway until fast flowing water passing along the first side of the containment boom from the first end to the second end exerts an equalizing force upon the floating appendages to maintain the containment boom in a  static equilibrium within the fast flowing waterway.

Title: Multiaxis rotational molding method and apparatus
Inventor: PAYNE LEROY
IPC: B29C41/22
Filed: 1995-05-18
Abstract: A method of continously forming an integrally molded struc-ture in a multiaxis rotational mold-ing operation includes the steps of rotating a multisection mold assem-bly (33) about at least three axes. A first freshly formed polymeriz-able mixture is flowed over sur-faces of an enclosed mold cavity (36) within the multisection mold assembly. The flowing of the first mixture over the mold cavity sur-faces and formation of a first resin therefrom is monitored. A sec-ond freshly formed polymerizable mixture is flowed under pressure through an orifice (41) into the mold cavity. A liquid stream of the second mixture is formed. The liquid stream is gelled as it ad-vances through the mold cavity to form a continous filament (73) with structural integrity. The fil-ament is contacted with the first resin formed within the mold cav-ity. The filament is distributed over the first resin in a preselected pattern. A third freshly formed polymerizable mixture is flowed over the filament pattern.

Title: Modulated release from biocompatible polymers
Inventor: BERNSTEIN HOWARD
IPC: A61K9/70
Filed: 1995-05-03
Abstract: The present invention relates to a composition for the modulated release of a biologically active agent.  The composition comprises a biocompatible polymeric matrix, a biologically active agent which is dispersed within the polymeric matrix, and a metal cation component which is separately dispersed within the polymeric matrix, whereby the metal cation component modulates the release of the biologically active agent from the polymeric matrix.  The present invention also relates to a method for modulating the release of a biologically active agent from a biocompatible polymeric matrix, comprising the steps of dissolving a biocompatible polymer in a solvent to form a polymer solution and also separately dispersing a metal cation component and a biologically active agent within the polymer solution.  The polymer solution is then solidified to form a polymeric matrix, wherein at least a significant portion of the metal cation component is dispersed in the polymeric matrix separately from the biologically active protein, and whereby the metal cation component modulates the release of the biologically active agent from the polymeric matrix.

Title: Functionally active domains of signal transducer and activators of transcription (stat) proteins
Inventor: HORVATH CURT M
IPC: A61K48/00
Filed: 1995-12-28
Abstract: The present invention relates generally to intracellular receptor recognition proteins or factors, termed Signal Transducers and Activators of Transcription (STAT), to methods and compositions utilizing such factors, and to the antibodies reactive toward them, in assays and for diagnosing, preventing and/or treating cellular debilitation, derangement or dysfunction. More particularly, the present invention relates to particular functional domains of molecules that exhibit both receptor recognition and message delivery via DNA binding in receptor-ligand specific manner, i.e., that directly participate both in the interaction with the ligand-bound receptor at the cell surface and in the activity of transcription in the nucleus as a DNA binding protein. The invention likewise relates to the antibodies and other entities that are specific to the functional domain of a STAT protein and that would thereby selectively modulate its activity.

Abstract: A locking package structure wherein the package will provide a convenient and safe disposable receptable for the syringe and the needle thereon and which can then be closed so as to prevent the syringe and needle from being a hazard. The open box receives the used syringe at the bedside and then can be snapped shut and locked for a safe disposal. The wall thickness of the package is thick enough so that the needle on the syringe cannot readily puncture the wall of the package and thus provides a safe disposal unit for the needle. A  locking key is provided for locking the package so that access to the used syringe within the package cannot be attained after the locking key has been inserted into and lockingly engages the covers.
