Abstract: A system, including a compressor including a cylinder with a chamber, a first axial end portion, and a second axial end portion, and a piston in the chamber of the cylinder, the piston is configured to reciprocate along a cylinder axis between the first and second axial end portions, and a co-axial flow device coupled to compressor, the co-axial flow device includes a first wall disposed about a first passage along an axis, a second passage disposed about the first wall along the axis, and a second wall disposed about the second passage along the axis, the first passage includes a first axial opening in fluid communication with the chamber while the piston moves in a first axial direction, and the second passage includes a second axial opening in fluid communication with the chamber while the piston moves in a second axial direction opposite from the first axial direction.

Abstract: The present invention relates to a continuous, horizontal process for making water-reactive pouches, involving the steps of: a) continuously feeding a first water-soluble film onto a horizontal portion of an continuously and rotatably moving endless surface, which comprises a plurality of moulds, or onto a non-horizontal portion thereof and continuously moving the film to said horizontal portion; b) forming from the film on the horizontal portion of the continuously moving surface, and in the moulds on the surface, a continuously moving, horizontally positioned web of open pouches; c) filling the continuously moving, horizontally positioned web of open pouches with a product, to obtain a horizontally positioned web of open, filled pouches; d) closing the web of open pouches, to obtain closed pouches, preferably by feeding a closing material onto the horizontally positioned web of open, filed pouches, to obtain closed pouches; and preferably sealing the closed pouches and whereby step d) and preferably step

Abstract: A substantially rectangular piece of flexible web having a first end and a second end and an elastic portion therebetween stretchable along a longitudinal axis of the piece of flexible web. The piece of flexible web has a length great enough to encircle a user's knee such that the first and second ends overlap. The first end has a reclosable fastening system for attaching the first end to the piece of flexible web near the second end in order to hold the piece of flexible web around the user's knee when the piece of web is stretched. The piece of flexible web also has an aperture therein. The aperture is aligned with the user's patella to establish a convenient locating point for wrapping the knee wrap around the user's knee. The piece of flexible web further includes a means for extending the piece of flexible web transverse to said longitudinal axis at the aperture in order to accommodate bending of the user's knee.
