Reg Technologies Inc. & REGI U.S., Inc. Complete RadMax Drive Shaft

VANCOUVER, British Columbia--Nov. 22, 2011: REGI U.S., Inc. (OTC BB: RGUS, Frankfurt Stock Exchange: RGJ) and Reg Technologies Inc. (TSX Venture Exchange: RRE.V, OTC BB: REGRF) are pleased to announce that they have completed fabrication of the RadMax drive shaft for the demonstration model.

Robert Grisar, Vice President of Engineering for REGI U.S., Inc. said, "The drive shaft is similar to a crank shaft in a reciprocating engine as it delivers rotational power to the transmission, however, the center is hollow and provides a path for oil to cool rotating components." The drive shaft works in conjunction with the rotary union (see news release of September 29, 2011).

The detailed thermodynamic analysis of the patented RadMax engine was performed last year in conjunction with Belcan Engineering Services of Phoenix, AZ. As a result, a design decision was finalized to create a hollow drive shaft to provide a means to lubricate internal rotating components. Without this device, the internal engine heat would make adoption of aluminum components impossible. By reducing heat, and weight, this leads to enhanced fuel economy in every RadMax application.

The drive shaft features include mounting provisions for the Rotary Union, Shaft Lock Nut which preloads the Rotor, main bearings, and tight pilots for securing the rotor in position. It includes key slots for securing the load to RadMax (such as a transmission).

This fabrication of the drive shaft was one of the steps that were described in the RadMax test and certification process presented in our March 8, 2011 news release.
