    • There is provided an apparatus for producing a cross-sectional angular surface along a substrate, such as a flexible electrostatographic imaging member belt, comprising a cutting blade that is angled at an angle of less than 90° relative to a plane of an associated substrate to be cut. An apparatus may include a support body, and a blade support member connected to the blade support body. The blade support member comprises a cutting blade having a blade edge. The cutting blade may be positioned, in some embodiments, at an angle of less than 45°, and in other embodiments from about 5° to about 15° relative to a plane of an associated substrate to be cut. The cutting assembly may be used to form a sloping surface on each of first and second marginal end regions of a substrate, such as a flexible electrostatographic imaging member belt, wherein the second sloping surface is substantially parallel with the first new sloping surface. A seamed, flexible electrostatographic imaging member belt may be produced by forming the sheet into a loop and overlapping said first new sloping surface with said second new sloping surface to form a mated region; and, joining said first new sloping surface to said second new sloping surface in the mated region to form a thin profile butt-lap seam.
    • 提供了一种用于沿着基底(例如柔性静电成像构件带)生产横截面角度表面的装置,包括切割刀片,该切割刀片相对于相关联的基底的平面以小于90度的角度成角度 被切断 装置可以包括支撑体和连接到叶片支撑体的叶片支撑构件。 叶片支撑构件包括具有叶片边缘的切割刀片。 在一些实施例中,切割刀片可以相对于要切割的相关联的基底的平面以小于45°的角度,在其他实施例中被定位为约5°至约15°。 切割组件可以用于在基底的第一和第二边缘端部区域中的每一个上形成倾斜表面,例如柔性静电成像构件带,其中第二倾斜表面基本上平行于第一新的倾斜表面。 可以通过将片材形成环并且将所述第一新的倾斜表面与所述第二新的倾斜表面重叠以形成配合区域来生产缝合的柔性静电摄影成像构件带; 并且将所述第一新的倾斜表面连接到所述配合区域中的所述第二新的倾斜表面以形成薄的轮廓对接接缝。

    • A self wear compensating valve for controlling flow of a fluid employs seals for sealing between relatively moving parts. In one of the parts, an annular recess is formed. A conformable sealing member is placed in the recess, and a spring biased to expel the conformable sealing member and press it against a sealing surface on the other part is provided. An O-ring placed on the outside of the conformable sealing member prevents leakage of fluid through the recess outside of the conformable sealing member. As the conformable sealing member is worn away, after many cycles of the valve, the spring continues to press it against the sealing surface, while the O-ring continues to prevent leakage of fluid outside the conformable sealing member. A rotary valve suitable for railroad brake applications is provided, which controls flow of fluid from a supply to the brake cylinder, and provides for exhaust of fluid from the brake cylinder. The valve has a supply port, a delivery port and an exhaust. In one position, the supply port is connected to the delivery port through a passage in the rotor. In another position, the delivery port is connected to the exhaust port through a passage in the rotor. In a third position, the lap position, all the ports are blocked by the relative position of the rotor and the housing. Proportional control of fluid flow is provided by elongating the ports on the mating surfaces of the rotor and the housing in the direction of rotation.
    • 用于控制流体流动的自磨损补偿阀使用用于密封相对运动部件之间的密封件。 在其中一个部件中,形成环形凹部。 提供了一个适形的密封构件放置在凹部中,并且弹簧被偏压以排出适形的密封构件并将其压靠在另一部分上的密封表面上。 放置在适形密封构件的外侧的O形环防止流体通过适形密封构件外侧的凹部泄漏。 当适形密封件磨损时,在阀的许多循环之后,弹簧继续将其压靠在密封表面上,同时O形圈继续防止流体在适形的密封件外部泄漏。 提供适用于铁路制动应用的旋转阀,其控制流体从供给到制动缸的流体,并且提供从制动缸排出流体。 阀具有供给口,输送口和排气口。 在一个位置,供应口通过转子中的通道连接到输送口。 在另一位置,输送口通过转子中的通道连接到排气口。 在第三位置,膝盖位置,所有端口被转子和壳体的相对位置阻挡。 流体流动的比例控制通过沿转动方向延长转子和壳体的配合表面上的端口来提供。
