Abstract: Carbon steels and other hot-and cold-workable ferrous alloys generally have poor damping capacity as compared to that cast iron (gray cast iron, malleable cast iron and ductile cast iron). This is because the graphite in cast irons helps to absorb the damping force and depresses the damping wave. But cast iron can not be rolled into strip of sheet. By controlling the correlated concentrations of manganese, aluminum and carbon, Fe-Mn-Al-C based alloys are made to be  alpha  +  gamma  two-phase alloy steel with different  alpha  and gamma  volume fractions. With particular ferrite volumes, workable Fe-Mn-Al-C based alloys have equivalent and better damping capacity than that of cast irons especially in the high frequency side. Such alloys suppress the vibration noise that comes from machine rooms, motors, air conditioners, and etc. Chromium and other minor amount of elements can be added to this alloy system to improve the corrosion resistance.

Abstract: This invention provides a laminated type grain boundary insulated semiconductor ceramic capacitor which usually works as a capacitor to absorb noise of low voltages or noise of high frequencies, which exhibits a varistor function when a high voltage such as a pulse or static electricity is applied thereto, and which is composed of SrTiO3 as a chief component that enables the ceramic capacitor material and the internal electrode material to be baked simultaneously, and a method of producing the same. The reason why the simultaneous baking of the materials has become possible is that the composition is such that components making a material semiconductor are added to SrTiO3 with excess of Ti, and that Mn and Si both convertible into MnO2 and SiO2 respectively in baking are added. Though a process of surface diffusion of metallic oxides has been conventionally performed, it can be omitted. By only re-oxidation, a grain boundary insulated semiconductor capacitor is easily obtained. According to the invention in which the molded product after lamination is calcined in advance in the air, the laminated ceramic capacitor with varistor function minimizes the occurrence of such problems as breakage of internal electrode, delamination, cracks, reduction of sintering density and heterogeneous structure in the sintered body, and exhibits markedly improved electric properties such as capacity, voltage nonlinearity index α and varistor voltage, and reliability. With respect to these two points, the invention has a notable advantage in material composition and process.

Abstract: In such a position measuring device, a scanning unit (6) connected to a first machine part (1) scans the graduation of a material measure (14) which is arranged on a carrier member (7a); the carrier member (7a) is mounted, for its part, on a second machine part (2).

Abstract: Gaseous hydrocarbons, which are thermocatalytically stripped from natural gas/petroleum parent rocks in subsiding sediment basins or which penetrate the seal of natural gas/petroleum deposits, reach the earth's surface in trace concentration within a geologically short time. The transported hydrocarbon gases transfer information about the hydrocarbon potential, the organic facies and the stage of maturity of the stripping parent rock or about the characteristics of a deposit to the surface. According to the invention, this circumstance is utilised for making statements regarding the prospectivity of the underlying rock by means of measurements at the surface. The molecular and isotopic composition of the trace gases is measured and, allowing for the changes caused by the transport, the abovementioned information about the natural gas-/petroleum-geological state in the underlying rock is derived therefrom. The isotopic changes in the methane during the migration to the surface are quantified. The relationship of the original gas parameters, reconstructed in this way, from parent rock and deposit up to their present geological state and potential - that is to say the prospectivity - of the basin is derived. This makes it possible to provide, before drilling, data about the hydrocarbon potential which is available for filling a certain structure or regionally in a sediment basin, and about lateral changes thereof. Under special geological conditions, the existence of a deposit in the underlying rock can be directly proved, and lateral changes in the effectiveness of stripping can be recognised. Application of the method is therefore suitable for a considerable reduction in the risk of development prospects for crude oil and natural gas.

Abstract: A fully internally manifolded fuel cell stack is provided by each separator plate [40] and electrolyte [20] in the fuel cell stack having a plurality of aligned perforations [24] forming gas manifolds extending for the length of the cell stack. Each perforation through the separator plate is surrounded by a flattened manifold wet seal structure [46] [45] extending to contact the electrolytes on each face of the separator plate to form separator plate/electrolyte wet seals under cell operating conditions. Conduits through the extended manifold wet seal structure provides gas communication between one set of manifolds [24] and the anode chambers on one face of the separator plates, conduits through the extended manifold wet seal structure on the opposite face of the separator plates provides gas communication between a second set of the manifolds [25] and the cathode chambers on the other face of the separator plates, and conduits through the extended manifold structure of a reactant gas manifold [50] [51] provides communication to interspersed reforming chambers. Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing. This structure provides fully internal manifolding of and separation of fuel and oxidant gases to each of the unit fuel cells in the fuel cell stack while providing reactant gas to reforming chambers interspersed along the cell axis to reform hydrocarbonaceous gas and supply enhanced hydrogen content to the fuel supply manifold.

Abstract: Système déterminant un cylindre par interpolation, permettant d'usiner une surface cylindrique sur une pièce à usiner. Un dispositif (104) de correction du diamètre de l'outil calcule un vecteur décalé pour un diamètre d'outil, en fonction d'une forme à usiner définie par des coordonnées orthogonales imaginaires, et détermine le passage central de l'outil. Un dispositif (107) d'interpolation interpole ledit passage central et émet une impulsion d'interpolation (PCyi) correspondant à un axe linéaire imaginaire, et une impulsion d'interpolation (Pzi) correspondant à l'axe d'un cylindre. Pour convertir inversement les coordonnées orthogonales imaginaires en coordonnées relatives à un cylindre, l'impulsion d'interpolation (PCyi) est transformée en une impulsion (PCi) par un dispositif (108) de conversion d'impulsion, l'impulsion (PCi) étant destinée à faire tourner l'axe de rotation. D'autre part, deux dispositifs (105 et 109) calculent, respectivement, une composante correctrice (Vcy) au début d'un bloc et une composante correctrice (ΔVcy) synchrone. Ces composantes correctrices (Vcy, ΔVcy) sont interpolées par deux dispositifs (106 et 110) et sont ajoutées à l'impulsion (PCi) destinée à faire tourner l'axe de rotation. Ainsi, la surface coupante est commandée de façon qu'elle se trouve toujours juste au dessus de l'axe central de rotation et que la surface usinée soit en position verticale par rapport à la surface cylindrique de la pièce à usiner.

Abstract: An automatic beverage dispenser having a multiflavor automatic beverage dispensing valve (faucet) and including means for preventing color and flavor carryover from one drink to the next. The automatic dispenser includes an electronic control system with an on-board computer with a microprocessor which, when a drink vend signal is received by the electronic control system, first checks to determine whether a dark or light colored drink was requested, then checks the last vend to determine if it was a light or dark drink. If the drink ordered was a light drink and the previous drink was a dark drink, then the controller looks to see if the cup dispenser position is occupied. If it is occupied, the flush is delayed until it is free when the soda water will flush to cleanse the nozzle. After flushing, the vend is processed.
