  • Patent number: 6027043
    Abstract: A spraying device includes a nozzle head formed with an axial bore connectible to a source of pressurized liquid, an outlet orifice through which the liquid exits in the form of a jet, and a connecting passageway connecting the inlet end to the outlet orifice. A rod passes through the axial bore; and a liquid distribution member is secured to the rod at the outlet orifice to distribute the liquid laterally of the nozzle head. The rod carries an abutment at the bore inlet end and is displaceable axially and laterally within the bore. The connecting passageway of the axial bore, and the adjacent portion of the rod, include complementary conical surfaces defining between them a metering passageway for the liquid flowing to the outlet orifice such that, during operation of the spraying device, the axial position of the rod within the bore, as determined by the abutment, determines the output rate of the spraying device.

  • Patent number: 5939728
    Abstract: A method and apparatus for reading a latent image stored in a photo-stimulated luminescence imaging plate by scanning the imaging plate with a focussed beam of light of a first wavelength to stimulate the stored image to emit light of a second wavelength; collecting the light emitted by the imaging plate; and directing the collected light to a light detector which converts the collected light to electrical signals. The light emitted by the imaging plate is collected by a non-imaging optical system which includes a dichroic mirror selectively directing light of the second wavelength to the light detector and light of the first wavelength away from the light detector.

  • Patent number: 5907592
    Abstract: A method and apparatus for examining an object by rotating a radiant energy generator around the object while projecting a beam of radiant energy towards the object to impinge the object at a plurality of angles in each of a plurality of planes substantially perpendicular to the z-axis, and detecting radiant energy leaving the object after impinging same, to produce sets of projection measurements representing slices of the object in the planes. During rotation of the radiant energy generator, the radiant energy beam is sequentially modulated between two locations along the z-axis to produce, during each rotation of the generator, two sets of projection measurements representing two slices of the object, which projection measurements are used in an interlaced manner for reconstructing the image of the object.

  • Patent number: 5871489
    Abstract: A surgical implement particularly useful for implanting a prosthetic valve in an excised annulus includes a manually grippable handle, and a suture retainer carried by the handle and having an outer face carrying a coiled spring whose coils define an annular array of slits each having opposed yielding surfaces for receiving and releasably retaining sutures between selected coils. Optimum spacing of the sutures according to the shape of the excised annulus is attained by providing reference ribs between selected coils of the spring, and also by making the outer annular face of the suture retainer of substantially the same shape as that of the excised annulus. Implements are described, with a suture retainer and without a suture retainer, including an illuminating device for artificially illuminating the working area. Also described is a method of implanting a prosthetic valve in a quick and efficient manner using such implements.

  • Patent number: 5847703
    Abstract: In a method and apparatus for browsing through a motion picture in order to locate desired segments in the motion picture, frames are selected from sequential parts of the motion picture according to predetermined sampling critera, e.g., "by time", "by tag" or "by change". Each selected frame is reduced in size such that the screen can accommodate the simultaneous display of "n" frames. The frames are displayed sequentially at "n" sequential locations on the screen according to a predefined closed loop, each frame being displayed in its respective location for a time interval starting with a time delay "t.sub.D " after the start of the display of the frame at the preceding location in the loop and continuing until the loop has been completed with another frame displayed in its respective location. Thus, only the selected frames need be viewed in order to locate a desired segment, but each selected frame may be viewed for an extended time interval, equal to "nt.sub.D ".
