  • Patent number: 4674238
    Abstract: A guiding and transporting arrangement employs opposed guide rails which have longitudinally extending guide structure associated therewith for slidably accommodating a lead frame between the guide rails, which guide rails are slidably supported on transversely extending guide rods, and are drivingly coupled together by a threaded screw arrangement which can be driven to accurately move the guide rails inwardly and outwardly to adjust the spacing therebetween. A conveyor is disposed for cooperation with the guide rails and is disposed below the lead frames to drivingly displace the lead frames longitudinally along the guide rails.

  • Patent number: 4669230
    Abstract: A wet blasting machine having a blasting apparatus wherein slurry is supplied from a main hopper through a supply conduit to a blasting gun. Slurry can be bled from the supply conduit through a control valve into a vessel for collecting a predetermined volume of slurry. The weight of the vessel is measured to generate a first signal which represents the slurry weight, and hence the slurry concentration. The first signal is compared to a second preset signal which represents the desired slurry concentration. If the second signal indicates that the slurry concentration in the main hopper is less than the desired magnitude, then the comparator emits an output signal which activates a supply device for adding additional media to the main hopper. The supply device preferably includes a mixing hopper to which both dry media and slurry from the main hopper are initially fed and mixed, prior to the enriched slurry then being fed into the main hopper.
