Abstract: In a finishing apparatus, such as would be used with a copier or high-speed printer, an applicator places stickers on a folded sheet or booklet, to prevent the sheet or booklet from unfolding or opening. At one point in the operation, the folded sheet or booklet is “backed up” in its basic process direction to receive a sticker on its trailing edge, and backed up further so that the sticker is folded over the trailing edge by a pair of crease rolls.

Abstract: A refrigerant flow-control device is automatically operable between a normal or low-flow condition and a pressure relief or high-flow condition in response to pressure drop across the flow-control device, in one embodiment the flow-control device includes a tubular-shaped body having an inlet, an outlet, and a refrigerant passageway extending from the inlet to the outlet, a cylindrically-shaped restrictor secured within the tube and forming a second restriction, and a cylindrically-shaped collar secured within the tube and forming a poppet-valve flow passage. The collar is spaced-apart from the restrictor within the tube. A poppet is located within the tube partially between the restrictor and the collar and carries a valve element. The poppet is movable between a first position closing the poppet-valve flow passage to generally prevent refrigerant flow therethrough and a second position opening the poppet-valve flow passage to permit refrigerant flow therethrough. The poppet forms a first restriction.
