Zurab Shermadini, Rustem Khasanov, Matthias Elender and Alex Amato at PSI have looked at the design of a double-wall piston-cylinder pressure cell specifically designed for muon-spin rotation (μSR) ...

The folks at TRW have come up with a revolutionary idea for reducing the piston ring drag of the top compression ring. It is called the Pressure Balance Ring (PBR). Essentially, the PBR design amounts ...

[Scott] is building a DIY yeast reactor for his aquarium. What’s a yeast reactor? [Scott] wants to pump carbon dioxide into his aquarium so his aquatic plants grow more. He’s doing this with a gallon ...

The surface area of the plunger and the degree of spring compression determine the amount of pressure necessary to actuate the switch. When pressure on the plunger exceeds that exerted by the spring, ...

What makes piston ring selection and ring endgap so important to engine life and power? What's more, what makes that first engine firing so critical to proper break-in and longevity? Those first few ...
