    摘要： A rack and pinion gear assembly 10 (FIG. 1) includes a resilient bushing which urges the rack into meshing engagement with the pinion. An arcuate inside bearing surface 54 (FIG. 4) of the bushing 18 has a larger radius of curvature than the curved outside surface 52 of the rack 12 against which it bears. The rack thus makes tangent contact with the bushing 18. When one portion of the bushing 18 is worn and therefore excessive play appears in the steering gear assembly 10, the bushing may be removed from the housing 16 of the assembly and rotated 180.degree. and then reinserted into the housing to thereby provide an unworn bearing surface which slidably engages the rack 12. The bushing 18 includes a plurality of axially extending grooves 70, 72, 74, and 76 through which lubricant is supplied to the bearing surfaces 52 and 54. In a second embodiment (FIG. 5) the aperture 50b in the bushing 18b through which the rack 12b extends has a square cross section and is in tangent contact with the rack at two locations 84 and 86. In a third embodiment (FIG. 3) the aperture 50c in the bushing through which the rack 12c extends is composed of four arcuate segments 100, 102, 104, and 106 each having the same radius of curvature, and each having a different center of curvature 110, 112, 114, and 116, respectively. This provides tangent contact between the rack 12c and the bushing 18c at two axially extending areas 120 and 122.

    摘要翻译： 齿条和小齿轮组件10（图1）包括弹性衬套，其将齿条推向与小齿轮啮合。 衬套18的弓形内部支承表面54（图4）具有比其承载的齿条12的弯曲外表面52更大的曲率半径。 因此，齿条因此与衬套18切线接触。当衬套18的一部分被磨损并且因此在转向齿轮组件10中出现过度的作用时，衬套可以从组件的壳体16移除并旋转180度然后 重新插入到壳体中，从而提供可滑动地接合齿条12的未被磨损的支承表面。套管18包括多个轴向延伸的凹槽70,72,74和76，润滑剂通过该凹槽供应到支承表面52和54。 第二实施例（图5），齿条12b延伸穿过的衬套18b中的孔50b具有正方形横截面并且在两个位置84和86处与齿条正切接触。在第三实施例（图3）中， 齿条12c延伸穿过的衬套中的孔50c由四个弧形段100,102,104和106组成，每个弧形段具有相同的曲率半径，并且每个具有不同的曲率中心110,112,114和116 ，res 果断地 这在两个轴向延伸的区域120和122处提供了齿条12c和衬套18c之间的切线接触。

    摘要： Systems and methods for disposing of waste material are disclosed, in which a cross-belt magnet configuration is employed to separate ferromagnetic substances from waste material. For some embodiments, the system includes a first conveyor belt, a magnet, and a second conveyor belt. The first conveyor belt is configured to carry waste materials in a first direction. The magnet is located in proximity to the first conveyor belt such that the first conveyor belt is within range of the attractive force of the magnet. The magnet attracts the ferromagnetic substances. The second conveyor belt is interposed between the magnet and the first conveyor belt. The second conveyor belt is positioned non-parallel to the first conveyor belt, and is configured to carry the attracted ferromagnetic substances in a second direction, which is non-parallel to the first direction.

    摘要： A card guide is used in guiding a circuit board with respect to a chassis. The card guide includes a guide rail extending along the card guide in a first direction, an end portion configured for removably attaching the card guide to the chassis, and a finger extending in a second direction. The finger has a shape and size to allow interconnection with an adjacent card guide. The finger defines an endpoint of a space allowing airflow in a third direction past the card guide.

    摘要： A multi-step process is provided in which waste material is processed in two or more steps. Specifically, an earlier step of the process heats the waste material at a first temperature. This results in a release of vapors for materials having a boiling point that is lower than the first temperature. A subsequent step of the process heats some or all of the remaining waste material at a second temperature, which is preferably higher than the first temperature. The subsequent heating results in a release of additional vapors for those materials having a boiling point that is lower than the second temperature. A system configured to carry out the process is also disclosed.

    摘要： A system for treating a material includes first and second screw conveyors each having a rotary shaft and a helical flight extending radially outward therefrom, the flighting of the screw conveyors overlapping with each other, and first and second actuators operably coupled to the first and second screw conveyors in a one-to-one dedicated relationship to rotationally drive the screw conveyors independently of each other. In typical embodiments, also included is a system for varying the clocking position of the screw conveyors relative to each other, wherein the screw conveyor flights are axially adjusted with respect to each other between a normal position and an advanced and/or retarded position. Also disclosed are methods of varying the axial position of the screw conveyor flights with respect to each other between the normal and advanced and/or retarded positions.
