IPC: B22D11/128
Filed: 2005-01-14
Abstract: A plant for the continuous casting of aluminum strip, according to current construction type, has two counterrotating continuous casting rolls (1, 2), between which a casting gap (4) is formed. According to the present invention, the 1, continuous casting roll (1) is made of a copper material at least in its circumferential edge region, and the other, 2.  continuous casting roll (2) is made of a steel material at least in its circumferential edge region. The copper material should have a thermal conductivity .lambda.K of 230 to 260 W/m.cndot.K, and the steel material should have a thermal conductivity .lambda.,s of 30 to 40 W/m.cndot.K.  Rejecting the prevailing idea that casting can only be performed with two continuous casting roll materials of the same kind, so as to ensure uniform crystal growth, a continuous casting roll pairing of steel and copper is provided in the present invention. In order to ensure a qualitatively high value casting microstructure, the difference in the thermal conductivity of the continuous casting rolls should not exceed a factor from 5 to 9. A ratio of thermal conductivity .lambda.K of the copper material to thermal conductivity .lambda.s of the steel material of 6:1 to 8:1 has proven particularly favorable.

Patent CA-2533960-A1 (CA)
Inventor: SHERRER GORDON D
IPC: F03D1/00
Filed: 2006-01-11
Abstract: A method and system are disclosed for efficiently extracting power from the wind.  Stationary frames and or those self-aligning into diametric opposition to approaching winds incorporate wind-receiving inlets (WRI) to channel air currents blowing into first larger open ends. Momentum-induced compression proportional to wind velocity and WRI geometries cause air to exit from second smaller WRI ends at higher pressure.  Independently or in combination with elevated-pressure feeds accumulated by other WRI array-frames, wind thus diverted provides mass flow to variable throughput expansion nozzle(s) developing higher than ambient wind velocity discharge stream(s) there-from. Nozzle discharge(s) applied tangential to a disc turbine optimized for low-pressure operation, combined with the induction of its expanding exhaust stream into a separate high-velocity air-stream maximizes the differential pressure across the turbine translating into an increased rate of turbine rotation and electrical work output realized from a co-rotating alternator exceeding that of machines in the prior art.
