Abstract: A rigid piston and rod connection in a hydraulic accumulator wherein a piston rod extending through an axial bore in the piston has a retainer ring fitted in an annular groove in the piston rod. A cover plate over the end of the piston rod clamps the retainer ring between one side of the annular groove and a bearing plate on the front face of the piston to provide the rigid connection and hold the piston rod perpendicular to the piston.

Abstract: A cover for cylindrical pressure vessels wherein the cylindrical cover having a reduced diameter section at the end extends into the cylinder. A prop ring having a tubular section is positioned between the reduced diameter part of the cover and the cylinder for alignment and support of the cover with respect to the cylinder axis. A radial flange on the prop ring extends into a groove in the cylinder wall to position the cover longitudinally along the axis of the cylinder and prevent the cover from moving outward.

Abstract: A fluid volume indicator for tanks having a follower, the position of which is directly proportional to the volume of the fluid in the tank and a visible indicator between the follower and a fixed wall, the indicator being movable along the axis of the follower and being acted upon by the two opposed helical compression springs, one between the indicator and the follower and the other one between the indicator and the fixed wall of the tank so that the movement of the indicator is proportional to the movement of the follower.
Abstract translation: 用于具有随动件的液体的液体体积指示器，其位置与罐中的流体的体积成正比，并且在从动件和固定壁之间的可见指示器，该指示器可沿着从动件的轴线移动，并且是 由两个相对的螺旋压缩弹簧作用，一个在指示器和从动件之间，另一个在指示器和罐的固定壁之间，使得指示器的运动与跟随器的运动成比例。

Abstract: A CHECK VALVE HAVING A SPRING-LOADED POPPET HELD AGAINST AN ANNULAR VALVE SEAT WITH MEANS FOR DAMPING THE MOVEMENT OF THE POPPET IN BOTH OPEN AND CLOSING DIRECTIONS. THE STEM OF THE PPPET MOVES IN A BLIND BORE, THE BOTTOM OF WHICH IS CONNECTED TO THE DOWNSTREAM SIDE OF THE VALVE BY A RESTRICTED PASSAGEWAYS TO DRIVE DAMPING WHEN THE VALVE IS OPENING. A DAMPING ELEMENT ON THE POPPET HEAD CONTACTS THE SEAT AS THE VALVE CLOSES TO FORCE FLUID OUT OF AN ANNULAR CHAMBER BEHIND THE DAMPER TO PROVIDE DAMPING IN THE CLOSING DIRECTION.
