Title: Water wheel drive system for generation of electrical energy has blades on periphery of impeller each consisting of two pivoting blade leaves in pairs beside one another
Inventor: STERN KARL
IPC: F03B17/06
Filed: 1999-07-02
Abstract: A water wheel (1) for the drive of generators for the generation of electrical energy has a rotor driven by an impeller with blades on the periphery. The impeller axis is located transversely to the flow direction of the water and the turbine thus designed works entirely below water. The blades located on the periphery of the impeller consist each of two blade leaves (3). The blade leaves are located in pairs beside one another and are limited in pivoting fashion around a blade axis vertical to the impeller axis. This is so that when the peak of the blade axis points against the flow direction or has exceeded this point in the direction of rotation in an acute angle, the blade leaves unfold from one another and include an obtuse angle up to 180 degrees. When the peak of the blade axis points in the flow direction or has exceeded this point in the direction of rotation with an acute angle, they fold together and lie in a plane within five degrees from the vertical to the impeller axis.

Bei der Dekodierung der vom Übertragungskanal (5) empfangenen kanalkodierten Daten werden in einem ersten Schritt der innere Kanalkode und anschließend in einem zweiten Schritt der äußere Kanalkode dekodiert. Bei der Dekodierung des äußeren Kanalkodes wird zumindest ein Teil der nach der Dekodierung des inneren Kanalkodes verbleibenden Restfehler korrigiert. In einem dritten Schritt wird geprüft, ob die Daten korrekt dekodiert wurden. Für den Fall, in dem die Prüfung ergibt, daß die Daten nicht korrekt dekodiert wurden, werden die Schritte 1 bis 3 wiederholt. Andernfalls wird die Dekodierung abgebrochen.

Title: Carbon dioxide purification process for ethylene glycol plants
Inventor: AHMED IJAZ
IPC: C01B32/50
Filed: 2000-09-07
Abstract: A process is provided for production of substantially pure carbon dioxide from a CO 2  off-gas
stream from an ethylene glycol plant. Water is condensed from an off-gas stream which
contains unsaturated hydrocarbons, saturated hydrocarbons, chlorinated hydrocarbons, carbon
dioxide and water. The dewatered gas stream is subjected to catalytic oxidation in the presence
of excess oxygen whereby the unsaturated hydrocarbons, saturated hydrocarbons and chlorinated
hydrocarbons are oxidized producing an oxidation stream containing carbon dioxide, water and
hydrochloric acid. The HCl is removed with an absorbent and substantially pure carbon dioxide
is collected. The absorbent-contacted stream can be subjected to catalytic deoxidation in the
presence of hydrogen to convert unoxidized oxygen introduced in the catalytic oxidation to
water.
