StratSat provides a geo-stationary platform at 20 km altitude capable of remaining on-station for up to five years. Payloads include high speed Internet services, direct broadcast TV, mobile telecommunication, etc. The envelope operates as a super-pressure hull(i. e. with no ballonet pressure control system). The hull will be of laminated fabric construction with Tedlar/Teflon, helium/weather barrier developed from AT-10/04. Multiple catenary curtain system supporting a payload module enclosed completely by the envelope. [The] payload module... comprises a single structural module with an externally mounted payload/mission system. The payload module provides a home for all of the airship's primary systems except for the propulsion system. The systems are close packed within the highly insulated module ensuring efficient heat and energy management. The payload module is pendulum stabilised within the envelope. The solar array provides the sole source of renewable energy for the airship. The array is placed over the upper quarter of the hull and extends over approximately three-quarters of the length of the craft. The array can be realigned to the daily sun location/angle by the roll rotation of the whole airship. The energy collected by the solar array is stored for use during the night in the series of batteries. Located in the stored for use during the night in a series of batteries. Located in the payload module, the batteries run the propulsion system, airship services and provide power to the mission system for up to 14 hours(during winter). The airship is propelled and steered by means of a ’Contra-Rotating Coned Rotor’ mounted on a tailcone at the rear of the envelope, as a part of a compound propulsion system. The unit provides longitudinal thrust(to counter the prevailing stratospheric winds) and lateral force(for manoeuvering) to enable the airship to hold station within a 1 km cube. The airship will be equipped with a multi-channel Flight Control Sy

The disk-type centrifuge consists of a stack of thin disks in the shape of cones. The sedimentation takes place in the radial direction in the space between adjacent cones.... Feed enters at the center line of the rotating bowl and is accelerated by fins or channels at the bottom of the disk stack assembly before it is introduced into the bowl proper.... The heavy liquid separates quickly and settles to the bowl wall. Light liquid with some of the heavy liquid entrained as small drops enters the outside of the disk stack and flows up the sloped surfaces to the central portion of the disks. The entrained drops of heavy liquor are separated in the shallow layers between the disks and settle back to the bowl wall. Any solids contained in the feed are also settled to the bowl wall.... The bowl used with these machines contains a central stack of coned discs which ensure an almost constant length of flowpath, and the deposition of solids at the bowl wall produces only a minor reduction in the flowpath.

Parmi les centrifugeuses de décantation, on trouve les centrifugeuses à basse vitesse et celles à haute vitesse. Dans tous les cas, la partie essentielle de l'appareil est le bol, c'est-à-dire le rotor à paroi pleine. Les centrifugeuses à haute vitesse développent des champs centrifuges supérieurs à 5 000 g. Les appareils les plus courants sont les centrifugeuses à disques. L'intérieur du bol comporte un empilage d'une centaine de disques qui divisent le bol en fines couches entre lesquelles circule la suspension. Ces appareils ont souvent un bol percé d'orifices calibrés qui permettent une sortie en continu des solides décantés et d'une partie de la phase liquide lourde. Les centrifugeuses à disques constituent le matériel de séparation le plus compact que l'on puisse trouver : une machine qui débite 200 m³/h occupe un espace au sol inférieur à 4 m².
