Abstract: A rotary vane type air lock for feeding granular abrasive materials into a pressurized chamber having means to prevent the abrasive material from coming between ends of the vanes and the air lock housing. A baffle prevents impingement of the material on the vane ends just before they reach an edge of the inlet opening. A thin sheet of high velocity air directed across the vane ends blasts off any material clinging to the end before the vane end comes into pressure sealing relationship with the housing.

The improvement comprises the application of a layer of light reflective material on the peripheral surface and adjacent the tip whereby light will be reflected into the actual work area which may in some instances be dark.

Abstract: A floating inductor assembly for use in heating a generally conical valve seat formed concentrically around a central bore in an engine component, wherein the assembly is adapted to be moved toward and away from the valve seat by a selectively movable element. This floating inductor assembly comprises a carrier, an inductor having a shape generally matching the valve seat and mounted on the carrier, an aligning nose member extending from the carrier in a given direction and generally concentric with the inductor, and first and second flange portions supported on the carrier and extending radially outwardly in a direction perpendicular to the given direction of the nose member, whereby each flange portion is adapted to engage a coupling member for supporting the assembly onto the movable element in a manner to allow floating in the radial direction only.

Abstract: A device for spreading particulate material from a vehicle mounted dump bed includes a hopper device mounted transversely across a material discharge end of the dump bed and a broadcast spreader beneath one end of the hopper device. The hopper device includes first and second spaced end walls, a fixed back wall between the end walls, and an elongated auger extending between the end walls arranged to be rotated about an axis parallel to the back wall. Rotation of the auger causes particulate material entering the hopper device to be moved toward one end wall beneath which the broadcast spreader is located. Spreading through, dumping over, and cleaning of the hopper device are possible as a result of an independent cover member extending between the end walls and movable between three corresponding positions.

Abstract: There is provided an improvement in an apparatus for cutting a profile of a selected shape from a natural sheet material at a given location, which apparatus comprises a cutting platen having an upper generally flat cutting surface and a lower generally flat support surface. The platen is movable to the desired position relative to a cutter which moves along an axis downwardly against the cutting surface to cut the preselected shape from the natural material. In accordance with the improvement, there is provided a fixed anvil having a flat force reaction surface parallel to and facing the supporting surface of the platen so that the cutting action is against the anvil. The anvil can also form the structure for supporting the platen as it is moved into the cutting position.
