    摘要： A forming apparatus uses counteracting, hydraulically coupled pistons to form a dome structure in the bottom panel of the container, such as a beverage can. A pressure ring is on one piston, and a doming die is on the other piston. The pistons are received in a piston housing that also provides a primary fluid reservoir so that, when one piston moves in one direction to displace fluid, the displaced fluid moves the other piston in the opposite direction. The pistons are coaxial and one is received in the other. Return springs are provided to bias the pistons into a desired orientation. A secondary reservoir may be provided to receive overflow fluid. Here, a first one-way valve sets a threshold so that fluid will flow into the secondary reservoir when the pressure in the primary reservoir exceeds the threshold. A second one-way valve permits fluid to return to the primary reservoir when the return springs move the pistons to a starting orientation. The secondary reservoir also permits the pistons to have a limit stop for countermovement at which point they undergo common movement with fluid being overflowed into the secondary reservoir.

    摘要翻译： 成型设备使用反作用的液压耦合活塞在容器的底板（例如饮料罐）中形成圆顶结构。 压力环位于一个活塞上，另一个活塞上有一个拱形模具。 活塞被容纳在活塞壳体中，该活塞壳体还提供主流体储存器，使得当一个活塞沿一个方向移动以移动流体时，移动的流体沿相反方向移动另一个活塞。 活塞是同轴的，另一个是接收的。 提供返回弹簧以将活塞偏置成所需的方向。 可以设置二级容器以接收溢流流体。 这里，第一单向阀设定阈值，使得当主容器中的压力超过阈值时，流体将流入次级容器。 当复位弹簧将活塞移动到起始方向时，第二单向阀允许流体返回到主容器。 次级储存器还允许活塞具有用于反向运动的限位件，在这一点上它们经历共同的运动，流体溢出到次级储存器中。

    摘要： A trimming and piercing apparatus of an extremely high operation efficiency which is capable of trimming and piercing a work simultaneously. The apparatus comprises a fixed die provided with a work mounting surface and a piercing bore opened at the work mounting surface, and a movable die displaceable toward and away from the fixed die. A pair of movable blades and a pair of fixed blades are provided in a spaced opposed relation on the movable die and the fixed die, respectively, so that the movable blades are engageable with said fixed blades when the movable die is moved toward the fixed die. A cam slide having a piercing punch is slidably mounted on the movable die. A cam driver is mounted on the fixed die for driving the cam slide to move along the movable die toward the fixed die to place the piercing punch into fitting engagement with the piercing bore in the fixed die as the movable die is displaced toward the fixed die.

    摘要： A flexure hinge assembly wherein a pair of fixed telescoped tubular members are provided, each having one or more pairs of axially spaced slots extending through their walls, the ends of one slot of each pair terminating a predetermined circumferential distance from the corresponding ends of the other slot of the same pair to form at least two flexure portions between the ends. The flexure portions of one of the tubular members extend parallel to the axes of the members, and the flexure portions of the other tubular member extend perpendicular to the axes of the members. A method of manufacturing a flexure hinge assembly.
