1979 Ingersol-Rand Patent 4,157,234 Devices of this type, generally referred to as "scroll" pumps, compressors and engines, have two interfitting spiroidal or involute spiral elements of like pitch which are mounted on separate end plates. These spirals are angularly and radially offset to contact one another along at least one pair of line contacts such as between spiral cylinders. The pair of line contacts will lie approximately upon one radius drawn outwardly from the central region of the scrolls. The fluid volume so formed therefore extends all the way around the central region of the scrolls. In certain special cases the pocket or fluid volume will not extend the full 360.degree. but because of special porting arrangements will subtend a smaller angle about the central region of the scrolls. The pockets define fluid volumes which vary with relative orbiting of the spiral centers while maintaining the same relative spiral angular orientation. As the contact lines shift along the scroll surfaces, the ! pockets thus formed experience a change in volume. The resulting zones of lowest and highest pressures are connected to fluid ports." - Original Message - From: Frederick Sparber To: vortex-l@eskimo.com Sent: 10/6/2006 3:41:45 AM Subject: Re: Can it Replace the Wankle http://en.wikipedia.org/wiki/Scroll_compressor "A scroll compressor operating in reverse is known as a scroll expander, and can be used to generate mechanical work from the expansion of a fluid."

Howdy Jones, Surprising how many Texas AM engineering school undergrads are now tracking your posts on this subject via my secret code ring locationunder my keyboard. They asked me if I knew Jones I remarked that he lives over the other side of Eureka which is not even close to Dime Box.

Park Friday, 6 Oct 06 Washington, DC 1. THE PHYSICS PRIZE: LOOKING BACK AT THE EMBRYONIC UNIVERSE. Are we so fortunate that we live at a time when we can develop the theory of creation? George Smoot mused in a 1992 press conference http://bobpark.physics.umd.edu/WN92/wn042492.html . It was at the April Meeting of the APS in Washington; Smoot had announced results from the Cosmic Background Explorer mission launched in 1989. The COBE findings appear to confirm the Big Bang theory of the origin of the universe. Smoot, who is at the Lawrence Berkeley Laboratory, and John Mather of the NASA Goddard Space Flight Center, share the 2006 Nobel Prize in Physics for the COBE measurements. It was an exciting time. Sadly, however, it couldn't happen now. NASA has chosen to set aside relatively inexpensive science in favor of Hollywood sci fi spectaculars. 2. GIMME AN A: IMPORTANT PROGRESS MADE IN MANNED SPACE FLIGHT. One small step in data enhancement. After 37 years, the missing a turned up. An Australian computer programmer used high-tech software to analyze Neil Armstrong's One small step for man... quote. He claims Armstrong said a man just like he insisted. I tried to lip-sync it while listening to the tape, but couldn't squeeze the a in. I guess that's why I'm not an astronaut. 3. FUEL EFFICIENCY: THE DEMAND IS GROWING FOR SMALLER PEOPLE. According to Holman Jenkins in the Wall Street Journal, Detroit is talking small cars again, following the near collapse of the SUV market amid higher gas prices over the last two years. He points out, however, that the popularity of SUVs and pickups was linked to the obesity epidemic. People need taller cabs so they can fit behind the steering wheel and still reach the pedals. Meanwhile, gas prices have fallen 25% since the peak just two months ago, but they may be at the bottom. Reports that OPEC is preparing to cut production is already starting to raise oil prices. There is a way out. If we keep converting crop land to making ethanol, rising food prices will begin to reduce American waistlines. We just have to stay the course. 4. THE BOMB: THE AXIS OF EVIL IS TURNING UP THE PRESSURE. Foreign Ministers are gathering in London for crisis talks on how to deal with Iran's refusal to end its nuclear program, even as North Korea's threatens to conduct a test of a nuclear weapon. 5. NANO: FDA LACKS RESOURCES TO REGULATE THIS NEW TECHNOLOGY. There are 320 nanomaterials products already on the market, including cosmetics, dietary supplements, drugs and medical devices, with 200 more in the pipeline. However, there is no record of anybody being harmed, in spite of Prince Charles' worries about the world being reduced to a mass of grey goo by self-replicating nanodevices. We call such devices bacteria, http://bobpark.physics.umd.edu/WN03/wn050903.html . THE UNIVERSITY OF MARYLAND.
