Abstract

A control system for thermoelectric refrigerators is disclosed. The thermoelectric refrigerator includes at least one thermoelectric element that undergoes a first order change at a predetermined critical temperature. The element functions as a thermoelectric refrigerator element above the critical temperature, but discontinuously ceases to function as a thermoelectric refrigerator element below the critical temperature. One example of such an arrangement includes thermoelectric refrigerator elements which are superconductors. The transition temperature of one of the superconductor elements is selected as the temperature control point of the refrigerator. When the refrigerator attempts to cool below the point, the metals become superconductors losing their ability to perform as a thermoelectric refrigerator. An extremely accurate, first-order control is realized.

Permanent magnet flowmeter having improved output terminal means

Patent August, Charles [Darien, IL]; Myers, Harry J [Downers Grove, IL]

Disclosed is an improved permanent magnet flowmeter capable of withstanding bending stresses in the direction of induced emf signals. The flowmeter includes a unique terminal arrangement integrally formed with the flowmeter by trepanning opposing wall sections of the flowmeter body. The terminal arrangement provides increased flowmeter sensitivity by increasing the strength of the induced emf signals.

Solid-oxide fuel cell system having means for controlling tail gas combustion temperature

Patent Haltiner, Jr., Karl J.

In a solid-oxide fuel cell system, the fuel cell tail gas contains significant residual amounts of combustibles which are burned in a combustor with spent cathode air to reduce system emissions and to reclaim chemical energy in the form of heat, the hot exhaust being used to pre-heat air entering the fuel cell system. The tail gas combustibles content can vary widely as can the combustion temperature. When the temperature becomes unacceptably low, a control valve in the spent cathode air return is adjusted to divert a portion of the air around the combustor, thus enriching the fuel/air mixture andmore » « less

Method and apparatus for producing pyrolysis oil having improved stability

Patent Baird, Lance A.; Brandvold, Timothy A.; Muller, Stefan

Methods and apparatus to improve hot gas filtration to reduce the liquid fuel loss caused by prolonged residence time at high temperatures are described. The improvement can be obtained by reducing the residence time at elevated temperature by reducing the temperature of the pyrolysis vapor, by reducing the volume of the pyrolysis vapor at the elevated temperature, by increasing the volumetric flow rate at constant volume of the pyrolysis vapor, or by doing a combination of these.

Slippery liquid-infused porous surfaces having improved stability

Patent Aizenberg, Joanna; Vogel, Nicolas

Methods and articles disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising surface features with re-entrant curvature and an immobilized layer of lubricating liquid wetting over the surface features. The surface features with re-entrant curvature can be designed to provide high repellency even after failure or removal of the immobilized layer of lubricating liquid under certain operating conditions.
