27 May 1933TL;DR: In this paper, a cathode construction for a make-alive type converter for a vapor electric device is described. But this is not related to our work in this paper.
Abstract: My invention relates to a vapor electric device and particularly to a cathode construction for a make-alive type converter. The engineers employed in constructing and designing vapor electric converters have long realized that certain advantages could be obtained by operating a simple rectifier...

08 Feb 1994TL;DR: In this paper, an improved integrated gas turbine solid oxide fuel cell system was proposed. But the system was not shown to work well in the real world due to its high computational complexity.
Abstract: An improved integrated gas turbine solid oxide fuel cell system. The system has a compressor for producing compressed air that is pre-heated and then supplied to a solid oxide fuel cell generator. The solid oxide fuel cell generator, which is also supplied with a first stream of fuel, produces electrical power and a hot gas. In the solid oxide fuel cell generator, the unreacted portion of the fuel is combusted with the oxygen remaining in the hot gas to further heat the hot gas. The further heated hot gas is then directed to a topping combustor that is supplied with a second stream of fuel so as to produce a still further heated hot gas that is then expanded in a turbine.

07 Dec 1988TL;DR: In this article, an electrochemical generator is constructed with a plurality of electrochemical cells or cell bundles and insulation materials in the form of at least one of porous partition boards between cell bundles, porous generator insulation (44), porous cell support boards (45), porous fuel entry distribution boards (35), and porous fuel conditioner boards (53).
Abstract: An electrochemical generator apparatus (30) is constructed containing an electrochemical cell assembly which contains a plurality of electrochemical cells or cell bundles (41) and (43) and insulation materials in the form of at least one of porous partition boards (33) between cell bundles, porous generator insulation (44), porous cell support boards (45), porous fuel entry distribution boards (35), and porous fuel conditioner boards (53), where a gaseous fuel (46) containing hydrocarbons will contact the insulation materials, characterized in that at least one of the insulation materials is impregnated with metal atom containing material, where the metal is selected from the group consisting of (A) metals selected from the group consisting of Mg, Ca-Al combinations, Sr-Al combinations, Ce, Ba, and mixtures thereof, and, (A) metals plus Ni. The impregnated insulation materials may also be pre-heated in air so that the oxides are formed prior to their insertion into the generator apparatus. These electrochemical cells are contacted with a hydrocarbon fuel gas and operated at over 700° C. The metal oxides formed are effective in preventing cell assembly deterioration due to carbon deposition from the hydrocarbon fuel and any elemental nickel formed is effective as a fuel reforming medium.

12 Feb 1988TL;DR: In this paper, an electromagnetic contactor or motor controller is taught in which an energy efficient bounceless contact closing operation is utilized, where an electromagnetic closing coil voltage is sensed by the contactor control system and compared against a memory menu of stored delay angles for a wide range of sensed voltages.
Abstract: An electromagnetic contactor or motor controller is taught in which an energy efficient bounceless contact closing operation is utilized. An electromagnetic closing coil voltage is sensed by the contactor control system and compared against a memory menu of stored delay angles for a wide range of sensed voltages. The delay angles are applied to the conduction interval of a triac or similar gated device which is connected in series with the coil for controlling current flow therethrough. Depending upon the voltage sensed the amount of current flowing through the coil on a half cycle by half cycle basis is varied by the control system. The energy supplied to the armature of the electromagnetic closing coil is such that the armature attains a predetermined velocity during its closing operation which predetermined velocity is approximately sufficient to allow the armature to move to its final fixed closed disposition where the air gap between it and a permanent magnet is reduced to zero at a velocity of approximately zero. Generally only that much energy is supplied to the armature which is just needed to close the contacts and no more within practical limits.

TL;DR: Among 22 compounds examined for photoluminescence, only Mg/sub 4/Nb/sub 2/O/sub 9, CaTa, ZnTa, and Cd showed appreciable room temperature emission as mentioned in this paper.
Abstract: Among 22 compounds examined for photoluminescence, only Mg/sub 4/Nb/sub 2/O/sub 9/, CaTa/sub 2/O/sub 6/, and the metaniobates of Mg , Ca, Zn, and Cd show appreciable room temperature emission. With the exception of Mg/sub 4/Nb/sub 2/O/ sub 9/, all of these have the columbite structure; moreover, the only essentially nonluminescent columbite-type compound noted was ZnTa/sub 2/O/sub 6/. The absorption edges of the luminescent niobates lie at shorter wavelengths than those of otherwise similar compositions. This indicates a relationship between luminescence and the separation of energy states within the Nb--O bond, as influenced by structure. (auth)
