A pressure fluid power driving device for driving studs, nails or the like having a gas chamber including an accumulator piston movable against the force of the gas in the chamber by the action of a noncompressible fluid against the accumulator piston. The invention further relates to the use of noncompressible fluid acting at a first, relatively low pressure to force a brake spool to carry a ram upwardly into sealing engagement with a seat element. The ram is propelled downwardly with great vel...

A fluid free damper, comprising a spindle member; housing means mounted for relative eccentric rotation with respect to the spindle member; and engagement means interposed between the spindle member and the housing means for rotation along with one of the housing means and the spindle member with respect to the other one of the housing means and the spindle member so as to be deformably compressed between the spindle member and the housing means and thereby generate a resistive damping force bet...

In a wrapping machine for wrapping a plastic foil web (F) around an object, a gripping and cutting device (11) is connected to a lifting frame (3) supporting a circular guide track of a foil dispenser (6) so as to be vertically movable with the lifting frame.

A wrapping machine and a method for wrapping a plastic foil web (F) around an object. A gripping and cutting device (11) is connected to a lifting frame (3) supporting a circular guide track of a foil dispenser (6) so as to be vertically movable with the lifting frame. In the method, the wrapping action is started from a freely chosen point relative to the vertical direction of the object and ended correspondingly at a freely chosen point relative to the vertical direction of the object.

An adjustable adapter includes two arms, each having an axis, a surface substantially normal to the axis, wherein the surfaces of the arms face each other, an end and a passageway for fluid communication between the end and the opening, wherein one of the arm ends is for connection to an inlet of an applicator and the other arm end is for connection to an outlet of a container, and a fastener for pivotally coupling the arms. One of the arm surfaces is provided with a groove in fluid communicatio...

A novel fluid supply cup comprises a flexible liner integral with a container having an opening and a vent. A novel method of manufacturing a lined container comprises the steps of molding a container having a vented thick-walled portion and an integral flexible thin-walled liner, and folding the thin-walled liner into the thick-walled portion. Finally, a novel method of applying a fluid comprises the steps of providing a flexible liner integral with a container having an opening and a vent, loa...
