    摘要: Disclosed is a flow-through, particle analyzer and sorter apparatus for simultaneous optical and electrical impedance measurements on a stream of particles, comprising a flow cell having a pair of channels fluidly connected by a particle sensing aperture, through which the particles pass and are analyzed; a nozzle mounted at the end of the downstream channel so as to define a flow chamber; a sheath liquid which is introduced at the bottom of the flow chamber to hydrodynamically focus the particle stream and to jet the same in a liquid jet from the nozzle; and a system for creating droplets from the liquid jet and for thereafter sorting the droplets.

    摘要: A metering and transfer valve assembly particularly for use in particle analyzing apparatus for the study of particles in liquid suspension, the valve assembly having at least pair of inner and outer valve elements coaxially arranged in face to face frictional sealing engagement with a center valve element, each of the valve elements being independently rotatable, first passages defining a first flow path through the assembly, second passages defining a second flow path through the assembly, the first passages including a metering chamber for measuring and transferring a precise sample aliquot of sample flowing in the first flow path into the second flow path, the first flow path leading to a first exterior location and the second flow path leading to a second exterior location, and a drive fluid being introduced to the second flow path subsequent to transfer of said aliquot thereto for propelling said aliquot along the second flow path to the second exterior destination, the second destination being a flow scanning cell whereby an absolute count of the full content of said aliquot can be established. The first destination can be a flow scanning cell and the first flow path can lead liquid sample to said flow scanning cell before the aliquot is transferred to said path. A method of cytometric analysis is described as well as apparatus utilizing said valve assembly.

    摘要: A variable and reversible transmission, in which two co-linear shafts are provided with adjustably-locatable generally semi-spherical drive components or heads, with control means for changing and holding selected adjustments of the heads; and the heads drivingly engage one another, in whatever settings they are positioned, by acting through a pulley belt which may be either an idler for only transmitting torque from one head directly to the other, or may be a power member transferring power to another set of such heads, achieving both variability and reversibility of drive.
