Abstract: Various exemplary embodiments of the present invention would provide a back floatation panel comprising an inner panel and an outer panel. The inner panel and the outer panel would be joined to each other in such a way as to allow “bellowed” expansion of a space, or a “sleeve,” in between the inner and outer panels. The bellowed expansion space between the inner and outer panels would be adapted for accommodating, for example, a hydration bladder and/or an insert of high density polyethylene (“HDPE”) plastic for protecting the wearer's back. The inner and outer panels would be joined in such a way as to provide a pathway through which a hydration tube can be inserted. Various exemplary embodiments of the present invention would provide differentially cut fabric panels for covering buoyancy panels. An outer fabric panel, comprising an outer panel surface area, would be used to cover an outer surface of a buoyancy panel.

Abstract: A workpiece holding device for a vacuum unit has coolable or heatable transfer plates (2) displaceable independently of one another in a baseplate (1) and each comprising a heat transfer surface (3) which is surrounded by an O-ring (4), is connected to a pipe (5) and, with a workpiece (15) which is pressed against the O-ring (4) by a holder (16), encloses a gap (20). The holder (16) can be locked to the baseplate (1). After lowering of the holder (16) into a closed position and load-free locking to the baseplate (1), the heat transfer plates (2) are pneumatically raised until in each case a stop (23, 22) becomes effective between said heat transfer plates and the holder (16) and determines the width of the gap (20). The gap (20) is then filled via the pipe (5) with a heat transfer medium, e.g. helium. After processing of the workpiece (15), the heat transfer plates (2) are lowered and the holder (16) is released again in a loadfree manner.

The slide fastener system includes two zipper tracks, each track having a fabric tape adapted for attachment to one of the articles and a row of teeth mounted on the tape. The teeth on one track are interengageable with the teeth on the other track. A slider on at least one of the tracks is slidably moveable therealong to selectively engage and disengage the teeth of the two tracks and thereby attach and detach the articles. A bracket is configured for holding the two zipper tracks in close proximity and in a generally parallel arrangement so that when the slider is at an unlock position wherein no teeth are engaged, the tracks and respective tapes are slidable relative to one another.
