Abstract: An apparatus including a container directing a sand mixture through a plurality of conduits, a conduit associated with each drive wheel of an automobile through an intermediate valve body operatively opened by a cable mechanism. The organization is typically mounted within an engine compartment of an automobile. Further, the organization utilizes a nozzle head mounted at a terminal end of each conduit adjacent each wheel, with each nozzle head utilizing an apertured dispersion plate, wherein each aperture is selectively closed to define a selective width of path of sand directed adjacent each drive wheel of the automobile.

Abstract: A wafer transporting apparatus comprising at least one carrier for supporting a substantially circular thin wafer having a flat plane, the carrier including a supporting base for supporting the wafer thereon, and a electrostatic chuck provided in the supporting base and having a contacting surface which face-wise contacts the flat plane of the wafer supported on the supporting base. The electrostatic chuck attracts the wafer so that the flat plane of the wafer contacts the contacting surface of the electrostatic chuck when the electrostatic chuck is energized. A holder holds the wafer at a position which has a predetermined positional relationship with respect to the supporting base.

Abstract: A truck for separately storing and discharging recyclable materials has a container housing with at least one door in its rear wall. Partitioning members divide the interior space of the container housing into at least two pairs of transversely disposed compartments, one pair being disposed rearwardly of the other pair, and the rearward pair being spaced from said rear wall of the housing to define a fifth compartment. The partitioning members have gates therein, and a multiplicity of openings are provided in one side wall of the container housing for feeding different types of materials into the several compartments in which they may be separately stored and from which they may be separately discharged.

Abstract: An extendable boom fork lift vehicle is described wherein the boom and its actuator are positioned over the rear axle of the vehicle such that the weight of the frame between the front and rear axles and behind the rear axle may be reduced. A modified boom and jib are also described wherein the jib may be selectively fixed relative one telescoping member of the boom. A light-duty carriage is provided to operably engage and articulate a secondary heavy-duty carriage.

Abstract: A lifting device incorporating first and second arm assemblies with associated rotatable shafts and a platform rotationally connected to the second arm assembly so as to maintain a fixed relationship to a reference surface as the first and second arm assemblies are angularly moved from one position to another. The shaft associated with the first arm assembly is rotated about its axis as the first arm assembly is angularly moved so as to impart similar angular movement to the platform through a rotatable shaft of the second arm assembly; thereby maintaining the platform's fixed relationship to a reference surface. A second embodiment of the lifting device provides an additional device to adjust the angular orientation of the platform with respect to the reference surface, which allows the platform to be maintained in a level orientation when traversing an inclined reference surface.
