The preferred construction e...

A spread spectrum CDMA communications system for communicating data and/or digitized voice between a plurality of users to a plurality of PCN units. The spread spectrum communications system is located within a same geographical region as occupied by an existing FDMA, proposed TDMA or any other mobile cellular system. The spread spectrum CDMA communications system includes a plurality of PCN-base ...

It is known to provide a cuffed tracheal tube with a suction lumen that opens outside the tube through an aperture above the cuff, so that secretions that collect in the trachea above the cuff can be removed via the suction lumen. In the present invention the collar at the proximal end of the cuff is everted within the inflatable portion of the cuff so that the collar does not project beyond the i...

A water purification device with an inlet funnel (1), a sleeve (2) connected in a leak-tight manner to the funnel and an insert (3) which features approximately cylindrical side-walls (4), a sieve cover (5) and a sieve base (6) into which a granular detergent may be introduced. In order that collecting air or gases, for example, does not interfere with the flow of water requiring purification...
