  • Publication number: 20080098885
    Abstract: A device, method, and system for a piston assembly are disclosed herein. A piston may have an outer circumferential groove. A semi-rigid ring seal may be sized and shaped to fit within the circumferential groove. The semi-rigid ring seal may provide a seal between the piston and a bore of the piston. The semi-rigid ring may be positioned during assembly within the outer circumferential groove without stretching the semi-rigid ring.

  • Patent number: 5746366
    Abstract: A flexible web guiding apparatus including; a turnaround roller; a pinch roller positioned in driving engagement with said turnaround roller and defining a nip therebetween; and a web guide for accurately directing an end of the web into the nip defined by the turnaround roller and the pinch roller to cause the web to move between the pinch roller and the turnaround roller without stubbing against either roller. The accuracy of the web guide is achieved by wear plates that are affixed to the web guide and spaced apart to permit the web to move therebetween. The wear plates are maintained in friction contact with the turnaround roller for controllably maintaining the spacing between the web guide and the turnaround roller.
