摘要： A leg press machine that provides an increasing resistance curve which approximates the strength curve of a user. The machine has a weight stack that can move relative to a frame. The machine also has a push plate that is coupled to the weight stack by a cable which is guided and held in tension by a series of pulleys. The push plate is attached to a first linkage arm which is pivotally connected to a second linkage arm and a third linkage arm. The second and third linkage arms are pivotally connected to the frame, so that the push plate can rotate between a rest position and an extended position. Attached to the third linkage arm is a first rotating pulley that moves through an arc when the push plate moves between the rest and extended positions. The cable is coupled to the first rotating pulley, so that when the push plate moves toward the extended position, the arcuate motion of the pulley pulls the cable and lifts the weight stack. The linkage arms and pulley are assembled so that each successive displacement of the push plate and pulley, produces an incremental movement of the weight stack that is greater in length than the preceding incremental movement of the weight stack.

摘要翻译： 一种腿压机，其提供近似用户的强度曲线的增加的电阻曲线。 机器具有可相对于框架移动的重量堆叠。 机器还具有推板，其通过电缆联接到重物堆叠，该电缆被一系列滑轮引导并保持张力。 推板附接到枢转地连接到第二连杆臂和第三连杆臂的第一连杆臂。 第二和第三联动臂枢转地连接到框架，使得推板可以在静止位置和延伸位置之间旋转。 连接到第三连杆臂的是第一旋转滑轮，当推板在静止位置和延伸位置之间移动时，第一旋转滑轮通过弧形移动。 电缆耦合到第一旋转滑轮，使得当推板朝向延伸位置移动时，滑轮的弓形运动拉动电缆并提升重量堆叠。 联动臂和滑轮被组装成使得推板和滑轮的每个连续的位移产生重量堆叠的增量运动，其长度大于重量堆叠的先前的增量运动。

摘要： A method of propping at least one fracture in a subterranean formation, that comprises forming a plurality of proppant aggregates, each proppant aggregate comprising a binding fluid and a filler material, and introducing the plurality of proppant aggregates into the at least one fracture, is provided. Methods of fracturing a subterranean formation also are provided.

摘要： Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand control screen (e.g., screens, screened pipes, perforated liners, prepacked screens, etc.) and an outer shroud assembly mounted over the sand screen in the wellbore adjacent the zone to be completed, the shroud having perforated and blank (non-perforated) segments with the blank segments corresponding to selected intervals of the wellbore, for example problem zones such as shale streaks or isolated zones where flows are restricted by mechanical seals or packers, and injecting particulate material into the wellbore, whereby gravel packing takes place in the remaining length of the wellbore/shroud annulus without voids. The inner annulus between the shroud and screen provides an alternate flow path for the slurry to bypass the blocked intervals and continue with its placement. Mechanical seals or packers may be used in combination with the shroud and associated sand screen. The method is also applicable to placing gravel packs in a cased and perforated well drilled in the zone.

摘要翻译： 提供了用于完成由井眼穿透的地下区域的改进的方法和装置。 改进的方法基本上包括以下步骤：在邻近待完成区域的井眼中放置防砂筛（例如筛网，筛管，穿孔衬垫，预包装筛网等）和安装在井筒上的砂筛上的外护罩组件， 具有穿孔和空白（非穿孔）段的护罩具有对应于井眼的选定间隔的空白区段，例如诸如页岩条纹或隔离区域的问题区域，其中流被机械密封件或封隔器限制，并且将颗粒材料注入 井眼，因此在没有空隙的井筒/护罩环的剩余长度内进行砾石填充。 护罩和屏幕之间的内环提供了一种替代的流动路径，用于使浆料绕过堵塞的间隔并继续其放置。 机械密封或封隔器可以与护罩和相关的砂筛组合使用。 该方法也适用于将砾石填充物放置在在该区域钻出的套管和穿孔井中。
