Publication number: 20080041736Abstract: An adsorbent material package comprising an elongated pouch having first and second sealed longitudinal ends. A distinguishing orientation marker is integrally formed on one or both of the sealed longitudinal ends for orienting and identifying the package inside the mating assembly of a refrigerant system. The orientation indicator is formed by the same tooling used to cut-off the ends of the package when the package is being manufactured. These distinguishing marks may be configured in the shape of a notch, a āVā, a āWā, a half-square, a half-circle, or a variety of other shapes. In one exemplary embodiment, the indicator takes the form of a protruding area on one end of the bag, and an indented area on the other end of the bag. In other exemplary embodiments, the orientation indicator comprises multiple notches or holes in one or both of the sealed longitudinal ends of the adsorbent package.Type: ApplicationFiled: September 15, 2005Publication date: February 21, 2008Applicant: Flow Dry Technology LtdInventor: Glenn Perrine

Patent number: 7127908Abstract: A desiccant container (2) which comprises a generally cylindrically cross-sectioned cup, two dual-density fiberglass discs (6, 8), desiccant material (4), and a cap (16). The cup includes an outer annular portion, an inner tubular portion, and a bottom which connect together to define a space within. The cap (16) has a planar portion with an aperture for receiving the inner wall portion of the cup and is designed for receipt in the chamber to cover the opening. The cap further includes an outer annular rim portion extending transversely from the planar portion. The peripheral flange portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion so that the cap can be retained within the chamber in one of a number of axially spaced positions to prevent shifting of, and escape of the desiccant.Type: GrantFiled: January 12, 2001Date of Patent: October 31, 2006Assignee: Flow Dry Technology LtdInventors: David V. Flaugher, Glen D. Perrine, John M. Evans
