Abstract: A powered appliance includes a working member, a handle operably coupled to the working member and a control movable between a first position proximate the handle in which movement of the working member is permitted and a second position distant the handle in which movement of the working member is at least reduced. One of the handle and the control is configured to at least partially receive the other of the handle and the control when in the first position. At least one of the handle and the control includes a flexible member adjacent the other of the handle and the control.

Abstract: An improved ware plate useful for materials feeder equipment, and the like, includes highly efficient, durable and wear and abrasion resistant sliding surface for slidably contacting elements of the feeder equipment. In particular, the ware plate has a tetragonal zirconia polycrystal ceramic sliding surface for contacting an element of the feeder equipment having a zirconia-alumina ceramic composite sliding surface. Alternatively, the sliding surface of the ware plate is zirconia-alumina ceramic composite for sliding contact with the element of the feeder equipment having a tetragonal zirconia polycrystal ceramic sliding surface.

Abstract: An improved materials transporting element useful for transporting materials in sliding contact with a ware plate, for instance in materials feeder equipment, has a high precision, durable, wear and abrasion resistant sliding surface. The transporting element may have a tetragonal zirconia polycrystal ceramic sliding surface for reciprocal sliding contact with the ware plate having a zirconia-alumina sliding surface. Alternatively, the transporting element may have a zirconia-alumina ceramic composite sliding surface with the ware plate having a tetragonal zirconia polycrystal ceramic sliding surface.

Abstract: An improved die retaining element has a highly efficient, durable and wear and abrasion resistant flange portion surrounding an opening for securing a die mold therein. The flange portion may have practically any geometric configuration, such as round, but is most effective when in a continuous plane with the powder feed box in sliding contact with a feed box. In particular, the flange portion may selectively have either a high precision tetragonal zirconia polycrystal (TZP) ceramic or zirconia-alumina ceramic composite, depending on the surface material of the feeder box in sliding contact therewith. In one embodiment, the flange portion has tetragonal zirconia polycrystal ceramic and the feeder box has zirconia-alumina ceramic composite sliding surface. In another embodiment, flange portion has a zirconium-alumina ceramic composite sliding portion and the feeder box has a tetragonal zirconia polycrystal ceramic sliding portion.

Abstract: A fluid power system comprising a steam generator connected to a hydraulic pumping device for delivering steam under pressure to the device for driving the same, while steam is returned to the steam generator via a condenser. The hydraulic pumping device is connected by means of suitable conduits to a plurality of hydraulic motors for driving the same and the conduits include valving means for controlling the direction of fluid between the hydraulic pumping device and the hydraulic motors and returning fluid to a reservoir from which fluid is initially drawn by the hydraulic pumping device. The hydraulic motors provide a rotary output for driving the wheels of a vehicle on which the fluid power system is used. The system further comprises valve means for controlling the pressure at which the system operates.
