  • Patent number: 5188633
    Abstract: Apparatus for selective destruction or inactivation of cells is disclosed wherein cells are arrayed in a plane for successive illumination, by optical X-Y scanning devices, with a first low powered light beam to produce in particular cells certain radiations responsive to the illumination. These response radiations are detected and used to enable a second higher powered light beam directed through substantially the same optical scanning paths, to destroy or inactivate the cells producing the response radiations. The illumination, response, detection, and high power radiation steps are accomplished by devices acting in times short as compared to the X-Y scanning devices so as to make the accurate treatment of each of large numbers of cells highly effective.

  • Patent number: 5141387
    Abstract: A hydraulically operated handler for drums and the like is mounted on the boom of a tractor so as to be selectively pivoted from a vertical position to fifteen degrees past a horizontal position. Grappling arms are mounted on a front plate which is selectively rotatable through by a hydraulic motor. A spindle rotatably supporting the front plate contains hydraulic operating fluid passages which are coupled through a rotating coupling mechanism to hydraulic cylinders operating the grappling arms. The selective pivotal motion together with the ability to selectively rotate the grappling hooks enables effective gripping and handling of drums.

  • Patent number: 5063767
    Abstract: A system and device for enabling the control of time intervals between billets in rolling mills of blocks or billets and/or similar equipments that allow such control is implemented using sensor controlled electronic circuits.The control system relies on a signal indicator which indicates to a mill operator the proper moment at which a billet has to be introduced in the first stand of the rolling mill. By observing a preset time interval and a real time interval indicator between billets, an effective time interval control technique for establishing an ideal spacing between billets minimizes the spacing gap guaranteeing, among other benefits, a significative increase in rolling mill productivity.
