Mobile Air Conditioning System Connection Having A Captured O-Ring

US Patent:
6641179, Nov 4, 2003
Filed:
May 9, 2002
Appl. No.:
10/142742
Inventors:
Ronald Allen Decoteau - Carnation WA
Steven Jay Wierlo - Covington WA
Assignee:
Paccar Inc - Bellevue WA
International Classification:
F16L 3714
US Classification:
285379, 285347, 285353
Abstract:
An improved fitting for mobile air conditioning systems is disclosed that reduces the risk of damage to fitting O-rings during assembly, the fitting male member being compatible with the fitting female member of many existing fittings currently in service. In particular, the male fitting ( ) is compatible with female fitting ( ) that comply with the IMACA 305 Standard. The male fitting includes a circumferential bead ( ) that engages the distal end of the female member, an intermediate tubular portion ( ) that extends distally from the bead, a tubular pilot portion ( ) that extends distally from the intermediate portion, and a retainer bead ( ) disposed between the intermediate and pilot portions. The retainer bead is positioned to retain the O-ring ( ) near the circumferential bead, without interfering with proper compression of the O-ring, and full insertion of the male member into the female member.

Exercise System

US Patent:
5547439, Aug 20, 1996
Filed:
Mar 22, 1994
Appl. No.:
8/216007
Inventors:
R. Lee Rawls - Woodinville WA
Steven J. Wierlo - Kent WA
Cathy L. Wade - Monroe WA
Assignee:
StairMaster Sports/Medical Products, Inc. - Kirkland WA
International Classification:
A63B 2100
US Classification:
482 5
Abstract:
An exercise system using a plurality of exercise cycles with the users applying user exercise force at user exercise speed. The exercise system includes a display displaying user indicators moving along respective paths of travel on the display simulating the movement of cycles therealong. The paths of travel are displayed to simulate the travel of a plurality of cycles racing against each other. The exercise system further includes a display control measuring the exercise speed of the plurality of users applied to their respective exercise cycles, and determining the applied cumulative exercise efforts of the users. The display control also determines a lead user based upon which of the users has the greatest cumulative exercise effort, and determines when the cumulative exercise effort of particular ones of the users are within a preselected range less than the cumulative exercise effort of the lead user. While the cumulative exercise effort of the particular users remains within the preselected range and in response thereto, the display control adjusts upward the cumulative exercise effort of the particular users by predetermined amounts. The display control controls movement of the user indicators along their respective paths of travel on the display, with the displayed movement of the user indicators along their respective paths of travel being indicative of their respective adjusted cumulative exercise efforts.
