Topflight Corp., Membrane Switch Div., Booth 1101 Wire Braider A horizontal 16-carrier fine-wire braider comes complete with a belt puller that is controlled via "intelligent motion control." Braid angle or pick density can be changed on the fly. The unit has been
  • Color and contrast
    reflection angle, makes the single lens configuration possible. Photoelectric sensors working with targets farther away generally use two different lenses for transmission and to collect reflections. Luminescence sensors and some contrast sensors incorporate a semitransparent mirror to beam light

    an angle. Automated deburring of needles using microabrasive blasting techniques requires two nozzles: one nozzle projects glass beads to kick out the burrs while a second one pushes them away. To remove a burr from the heel area of a needle, the abrasive stream must strike at an exact location and angle
  • Medical Device Link .
    too slow and operator intensive. ". Trial and Error. Popper initially identified the main factors of automation as uniform coverage, controlled blast time, and proper nozzle angle. Theories were tested by integrating the microabrasive blasting equipment into a cabinet equipped with tooling to hold
  • Medical Device Link .
    . The resonance shifts the reflectance maxima (angle difference), and the reflectance determines the quantity of binding on the surface. This technique does not require labels and is an ideal system for immunoassays, or binding-recognition events, and kinetic studies of the interaction of biomolecules

The angle and. symmetry of the flow lines is an indication of the degree to which the edges are pre-. sented flat and parallel. The specimens should
