摘要： Electrical oscillations are supplied to electrodes of a diathermal heating chamber. A liquid is passed through the diathermal heating chamber so as to be heated. The liquid has a minimum level of dissolved solids, which is replenished over time or when the dissolved solids in the liquid fall below a predetermined minimum level. Alternatively, when the level of dissolved solids is excessive, current input or liquid temperature is reduced.

摘要： A method for generating heat includes passing a liquid between electrodes connected to an alternating current power supply. The liquid must have a sufficient level of electrolytes or dissolved minerals so as to be effectively heated. The level of current applied to the electrodes is preferably monitored and controlled. Exothermic, electrochemical reactions occur within the liquid and at the surface of the electrodes. More particularly, the electrodes are comprised of a material that can be oxidized, and the oxidation process during operation of the heater supplies additional current to heat the liquid.

摘要： A method of microfluidic control via localized heating includes providing a microchannel structure with a base region that is partially filled with a volume of liquid being separated from a gas by a liquid-gas interface region. The base region includes one or more physical structures. The method further includes supplying energy input to a portion of the one or more physical structures within the volume of liquid in a vicinity of the liquid-gas interface region to cause localized heating of the portion of the one or more physical structures. The method also includes transferring heat from the portion of the one or more physical structures to surrounding liquid in the vicinity of the liquid-gas interface region and generating an interphase mass transport at the liquid-gas interface region or across a gas bubble while the volume of liquid and the gas remain to be substantially at ambient temperature.

摘要： An antenna for a land-based, mobile radio communication system, having a reduced size and shape, includes three, flat antenna dielectric panels, each covering one hundred, twenty degrees of azimuth. On each dielectric panel is formed two, interleaved microstrip antenna arrays having narrow vertical beam width. One of the antenna arrays receives signals and the other antenna array transmits signals. The receive array is circularly polarized. The panels are mounted in a triangular configuration about a central mast and a cylindrically shaped radome encloses the dielectric panels.

摘要： Feed mixtures containing one or more platinum group metals are fluorinated to form at least one volatile fluoride product which is separated from the residual solid. Separations of different fluorides may be effected by collecting different fractions of volatile fluorides. Palladium does not form a volatile fluoride and is retained in the residual solid.

摘要： A method for making mononitrobenzene using a plug flow reactor train. Benzene, nitric acid and sulfuric acid are introduced into the reactor and produced mononitrobenzene is removed at an outlet end. All of the benzene and at least part of the sulfuric acid are introduced at the inlet end of the reactor. A first portion of the nitric acid is introduced by a first nitric acid feed into the inlet end and a second portion of the nitric acid is introduced at one or more additional feeds that are spaced between the inlet end and the outlet end. The method results in reduced formation of by-product dinitrobenzene, improving the reaction yield of mononitrobenzene while avoiding the need for a distillation step.
