  • Patent number: 4949716
    Abstract: Disclosed is a hand-held medical device that attaches a wide range of nasally placed airway tubes to afford better control of said airway tubes, manipulation of said airway tubes by rotation and curvature the latter of which is provided by a soft, flexible manipulator containing a spring which is attached at its distal end by a braided wire the pulling of which will cause flexion of the manipulator and said airway tube that surrounds it. The device additionally allows for patient inspiration and expiration to pass unrestricted through the body of the device deflecting one-way valves positioned in clear tubes on the sides of the device allowing for visual confirmation of proper final placement of said airway tube. A stethoscope headset attached to the device provides an audible reference for guiding said airway tube and affords an additional reference to confirm proper final placement of said airway tube.

  • Patent number: 4610323
    Abstract: The invention relates to a combination weighing system for non-uniform weight items which comprises a plurality of hoppers that selectively empty by means of gates into a chute, and then usually into a packaging machine. The system further comprises check weighers associated with each hopper and a combination selection and machine control logic which typically receives weight signals from the check weighers and sends discharge signals to predetermined gates so as to combine items in order to achieve a nominal weight between a predetermined minimum weight and maximum weight. The improvement comprises a set point determining circuit which includes logic blocks to establish a changeable set point within the range of the maximum and minimum weights. The logic blocks allow weights below a set weight and/or maintenance of an overall average weight for the output of the system.
