Abstract: A swivel exhaust conduit for rotatably connecting a patient mask to the delivery conduit of a positive pressure air supply. The swivel exhaust conduit design provides an exhaust port that utilizes the rotating bearing of the swivel conduit's rotating two-piece design for permitting and directing exhaust of CO2 laden air. A baffle chamber formed in the clearance of the two pieces provides an area where noise is reduced. As CO2 laden exhaust exits the swivel exhaust conduit, it is directed away from the patient mask and down the outside of the delivery conduit via a slit pattern on the swivel conduit.

Abstract: A method and system are disclosed transmitting a message to a telephone station. Different routing strings are used to establish calls between different network elements, based on the location of the network elements with respect to one another. Different time delay periods are associated with the different routing strings so as to offset any differences in the time needed to setup the systems for the transmission of a message to a telephone station. This enables messages to effectively transmitted to the telephone stations so that they are complete and not cutoff.

Abstract: A swivel exhaust conduit for rotatably connecting a patient mask to the delivery conduit of a positive pressure air supply. The swivel exhaust conduit design provides an exhaust port that utilizes the rotating bearing of the swivel conduit's rotating two-piece design for permitting and directing exhaust of CO.sub.2 laden air. A baffle chamber formed in the clearance of the two pieces provides an area where noise is reduced. As CO.sub.2 laden exhaust exits the swivel exhaust conduit, it is directed away from the patient mask and down the outside of the delivery conduit via a slit pattern on the swivel conduit.

Abstract: A polarizer arrangement in accordance with the invention includes a circular depolarizer combined in a common component with a linear polarizer. The depolarizer material includes a recess within which a ferrite rod is located, a bias coil being wound around the polarizer and the rod. In another arrangement, a polyrod waveguide feed is also included in the component, being integrated with the circular depolarizer and the linear polarizer.
