  • Publication number: 20200216918
    Abstract: Described herein are uses of fluorescent enveloped virus particles as standards in nanoscale flow cytometry applications. The virus particles comprise a fluorescent dye or a fluorescent protein. A standard ladder comprising a plurality of fluorescent enveloped virus particles of different sizes is also provided. The standards may also comprise marker(s) of interest, and may be used as controls for detection of other viruses or extracellular vesicle, e.g. in diagnostic applications. Methods of producing controls for such applications are provided, including those having desired profiles. The controls may be used for enumeration of markers on microparticles (e.g. extracellular vesicles or viruses). Also described is a modified gammaretrovirus comprising a mutation that abolishes expression of the viral glyco-Gag protein, and having a fluorescent protein inserted in-frame into the proline-rich region (PRR) of the viral env protein.

  • Patent number: 6992411
    Abstract: A cooling arrangement for electric machines comprising a heat storing element provided with generally C-shaped channels and a cooling tube so configured and sized as to be insertable in said C-shaped channels of said heat storing element is described herein. The cooling tube, once inserted in the channels is deformed to conform to the C-shaped channels, whereby heat stored in said heat storing element is extracted by circulating cooling fluid inside the cooling tube.

  • Patent number: 5714824
    Abstract: The conductor section is for a stator frame of a polyphase dynamoelectric machine. The stator frame is provided with a series of elongated parallel slots for receiving respectively conductor sections. The conductor section comprises two parallel conductor sides of substantially rectangular cross section adapted to fit respectively into two corresponding parallel slots of the stator frame, the two sides defining a plane; and at least one conductor head of substantially rectangular cross section, connecting two adjacent ends of the parallel sides. The head shows a substantially U-shaped body when seen from a top view perpendicular to the plane, and a waved-shape body when seen from a front view contained in the plane. The head having top and bottom surfaces facing only one side of the plane from one end of the head to the other end thereof. Methods for mounting conductor sections of stator winding onto a circular shaped stator frame are also described.

  • Patent number: 5619787
    Abstract: A method for mounting conductor sections of a stator winding onto a circular shaped stator frame of a dynamoelectric machine. Each conductor section has two parallel conductor sides and at least one conductor head connecting two adjacent ends of the parallel sides. The stator frame is provided with circumferentially distributed parallel slots. One conductor side of each conductor section is inserted at least partially into a corresponding slot of the parallel slots. The other conductor side of each conductor section is positioned, one beside the other, along the stator frame. The other conductor sides are then circumferentially shifted with respect to the stator frame until the other conductor sides are superimposed respectively above the one conductor side for forming pairs of superimposed conductor sides.
