Abstract: A bell end in an extruded pipe having a transition phase of greater than 35°is formed by thermoforming. The transition phase acts as a pipe stop system to prevent over insertion of another pipe into the bell end. The process includes heating the first end of the pipe, pushing the pipe onto a mandrel having a sloped portion with a forming angle of more than 35° and applying pressure to conform the pipe to the shape of the working surface of the mandrel. The heating step includes heating an end of the pipe where the transition phase will be formed in a preliminary pre-heater, while the pipe is still warm from the extrusion process, and then immediately thereafter in a heating box. Preferably, the end of the pipe, and in particular the portion of the pipe corresponding to the longitudinal position where the transition phase will be formed, will be heated to an average temperature of at least 100°F and more preferably 200°F and still more preferably at 300°F. The number of heating zones in the heating unit and the duration of heating is selected to be comparable to the time required to extrude the pipe so that the overall thermoforming process can be performed substantially continuously with the pipe extrusion.

Title: Device for preventing leakage in the field of injection molding
Inventor: GAILLARD PATRICE FABIEN
IPC: B29C45/80
Filed: 2007-05-18
Granted: 2011-01-11
Abstract: A collar for reducing or eliminating leakage between components, which move with respect to each other in the field of injection molding. The collar has an outer portion for receiving an inner portion. The outer portion has a tapered or partial spherical surface on its inside diameter, and the inner portion has a tapered or partial spherical surface on its outside diameter. In the preferred embodiment, the inner portion of the collar is operatively assembled into a cavity of the outer portion of the collar, such that the tapered surface of the inner portion is slidably mounted to the tapered surface of the outer portion. The collar is operatively mounted around the outside diameter or circumference of a cylindrical device and between two components that move with respect to each other. Springs, discs, cylinders or other device are used to create an axial force AF between the components, which move with respect to each other. In order to facilitate movement between the components, a clearance is provided between the components. To avoid leakage or weepage from exiting the clearance, the collar and springs are incorporated between the components. The collar is designed to receive the axial force AF and redirect at least a portion of the axial force AF to a radial force RF. This radial force RF acts on an inner portion of the collar forcing the inner portion tightly into engagement with one of the two components, thereby sealing off the clearance or an area adjacent the clearance where leakage or weepage may occur.

Abstract: A ticket change constrainer which allows reissuing or revalidating an already issued airline ticket is described. It includes a ticket change domain reducer operable to reduce an input search domain of change opportunities on the basis of change conditions set in the already issued ticket. It also includes a ticket change valuer operable to weigh the change opportunities of the reduced search domain and to return a reduced valued search domain of change opportunities. The weighing of the change opportunities is done on the basis of pricing method popularity scores updated in a ticket change memory by a ticket change watcher agent from actual change transactions handled by the system. The change conditions include standard pricing methods of the airline industry. The input search domain of change opportunities is produced by a conventional fare-driven search engine on the basis of a ticket change request issued by an end-user of the system. The reduced valued search domain of change opportunities returned by the ticket change constrainer always includes a lowest fare opportunity compatible with the change conditions set in the already issued ticket.
