  • Patent number: 4645056
    Abstract: An improved material flow rail construction of the type employed to transmit containers or articles from one location to another gravity force. The improved material fow rail comprises a substantially U-shaped channel within which a multiplicity of mounting bolts are attached. Individual bearing assemblies are placed on the mounting bolts. By placing the individual bearing assemblies closely adjacent one another in a longitudinal direction with respect to the support channel, the flow rail has the ability to transmit parts having very small "footprint" areas since a large space between rollers is not presented for parts or components thereof to become caught. By providing a loose fit between the bearing inner races and the supporting mounting bolts, the inner race is permitted to rotate slightly with respect to the mounting bolts thereby presenting new wear surfaces as the flow rail is put into use.

  • Patent number: 4641738
    Abstract: A device that brings a vertically falling integrated circuit to a rapid, bounce-free stop at a test site includes a set of relatively lightweight blades arrayed next to the fall path with their faces in a mutually spaced relationship. At its upper end, each blade is pivotally and loosely mounted on an energy absorbing elastomeric sleeve. At its lower end, each blade carries a stop member that projects into the fall path when the blade is in a first ("test") position. The stop members are generally aligned with one another horizontally across the fall path to define a stop surface that precisely locates an integrated circuit at the test site. The device includes an arrangement for repeatedly drawing the lower ends of the blades in unison to a second ("release") position where the stop members are clear of the fall path.

  • Patent number: 4618295
    Abstract: The flow restrictor (10) comprises a resilient and flexible porous membrance (12) over an air inlet port (18). In one embodiment an impervious member (130) is attached to the lower surface of the membrane over the air inlet port. The membrane balloons due to air flow through the inlet which greatly increases its effective cross sectional area as air flows into the plenum chamber. When air flow stops gravity and/or air pressure from the container forces the membrane against the seat (118) and the effective cross section of the membrane is reduced to approximately that of the inlet port.
