Abstract: In twin-chamber compressed gas packs, the collar of a diaphragm which invaginates during motion in the container is secured with its opening region in a fold or in the upper part of the container, in order to provide the required sealing between product chamber and working fluid chamber. The disadvantage of packs of this type is that the use of multi-part containers is mandatory and/or that a support ring incorporated in the diaphragm produces a frictional force which may be large enough to prevent ejection of the feed material because of an insufficient pressure differential between the chambers. These drawbacks are overcome by securing the entire region of the collar to the internal wall of the casing.

Abstract: There are disclosed method and apparatus for stacking the output ("documents" or "printed products") of a high speed printing press or bindery line. The documents are shingled on a linear infeed conveyor where they are also aligned, positioned, and counted, all at high speed. When the amount of documents desired for a stack have been counted or weighed or determined by stack size or height, further document flow is temporarily interrupted. The documents are speeded up in an accelerator to reduce the amount of shingling. They are ejected from the accelerator to glide through the air onto a stack starter surface which slowly descends as the stack is formed. The partially completed stack is transferred to a de-elevator and the stack starter returns to begin building a new stack. The de-elevator lowers the completed stack onto a receiving surface and rises to receive the next partially completed stack from the stack starter surface. A pusher then removes the stack from the receiving surface.
