Recent Patents on Engineering - Volume 7, Issue 1, 2013

The present patents relate to power generating apparatus suitable for use in extracting geothermal energy. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. As our reliance on fossil fuels have started to decrease, geothermal energy is seen as one of the new sour Read More

Wine has a rich history dating back thousands of years. It has been object of several studies and experiments performed by researchers and simple passionate people. Different varieties of grapes, strains of yeasts, and technologies produce different types of wine. The well-known variations result from the very complex interactions between the biochemical development of the fruit, reactions involved in fermentation, and hu Read More

Pisco is a traditional beverage from Peru (South America) produced by the fermentation of pisco grapes. This article discusses the by-products of pisco production as a potential source of bioactive compounds; until now, pisco bagasse has had no industrial application. There is a knowledge gap that is the result of the lack of qualitative and quantitative information in the literature about the by-product of pisco production. Thus, w Read More

The lubrication of the piston ring has been an important research matter for many years because it is generally accepted that the interaction at the ring-cylinder wall interface provides considerable effects on friction, wear, oil consumption and power loss in internal combustion engines. This paper after a historical overview presents in the first section the main physical phenomena considered by the literature for the design a Read More

This paper presents a new design for a thermogenerator suitable for working on low-temperature (up to 175°C) BiTe modules. Its improvement is related to the cooling system that is a low-cost modular device based on domestic hotwater radiators working in a natural-convection loop. Thermal and cost analyses were performed, showing that a competitive 1kW unit could be built (with a specific cost of 21,300 U$D/kW) Read More
