Title: Process for metering hydrogen permeated in a metallurgical structure, and apparatus thereof
Inventor: CORREA LUIZ AUGUSTO DEMARIA
IPC: G01N17/02
Filed: 2000-12-01
Abstract: Patent of invention "Process for metering hydrogen permeated in a metallurgical structure", refers to a process for metering permeated hydrogen flow in machines, equipment, piping, or other metallic apparatus, through a sensor that uses the properties of a couple of dissimilar materials, in construction and installation that are suitable to measure electrical values between a metering couple and a reference couple. The measured value is a function of the flow rate of hydrogen that permeates the metallic surface under monitoring. In consequence, we obtain a process for measuring hydrogen corrosion or hydrogen flow through an apparatus.

Title: Gas supply device for precursors with a low vapor pressure
Inventor: KUPPER THOMAS
IPC: C23C16/455
Filed: 2001-01-27
Abstract: The invention relates to a gas supply device for delivering precursors with a low vapor pressure to CVD coating systems. Said gas supply device has a supply container for the precursor which is at a first temperature T1, an intermediate storage device for intermediately storing the vaporous precursor at a second temperature T2 and at a constant pressure p2, a first gas line between the supply container and the intermediate storage device and a second gas line for removing gas from the intermediate storage device. According to the invention, the gas supply device is developed in such a way that the first temperature T1 is higher than the second temperature T2. The lower temperature T2 of the intermediate storage device facilitates maintenance work on the same, while the precursor evaporates at a greater rate at the higher temperature T1 in the supply container. According to a particularly advantageous embodiment, a first precursor vapor is mixed with a gas and/or a second precursor vapor in the intermediate storage device. The partial pressure of the first precursor vapor in the intermediate storage device is lower than that of the undiluted first precursor vapor at a constant overall pressure in said intermediate storage device, so that the temperature T2 of the intermediate storage device and the successive lines can be reduced.  Reducing the temperature T2 allows less expensive components to be used.

Title: Method for operating a switched reluctance electrical generator
Inventor: KAPLAN MARTIN
IPC: H02P9/00
Filed: 2001-02-09
Abstract: A method for operating a switched reluctance electrical generator in a manner that is highly efficient involves initially performing a mapping technique to obtain data relating to all of the possible operating conditions of the generator system that generate the desired output power. This mapping technique can be performed empirically or by computer simulation. Then, the effective phase currents supplied to the windings on the stator are measured or calculated. Next, the optimum conduction angles can be selected as those turn-on angles and turn-off angles that occur using the smallest effective phase currents supplied to the windings on the stator. Lastly, the generator system is operated using the selected optimum turn-on and turn-off angles. If desired, a feedback loop can be provided for comparing the actual output power that is generated by the generator system with a desired reference output power level to insure that such actual output power is maintained at or near the desired output power. To accomplish this, the conduction angles can be adjusted in response to such comparison to increase or decrease the actual output power as necessary.

Title: Method and strand guide for supporting, guiding and cooling casting strands made of steel, especially preliminary sections for girders
Inventor: ZAJBER ADOLF GUSTAV
IPC: B22D11/00
Filed: 2001-08-07
Abstract: A method and strand guide for supporting, guiding and cooling casting strand s (1) made of steel, especially preliminary sections (2) for girders, which ar e cooled by injected water (29) and are drawn. The inventive method prevents cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand during secondar y cooling. Undercooling of the chill of the strand is prevented by adapting th e cooling and support of the beam blank format to the solidification range in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas so that cooling and support are provided exclusively where a crater is formed. The casting strand (1) is cooled by guiding the temperature in a specific manner in upper supporting segments (5, 6, 7) by means of injected water jets whose width at least matches the length of the supporting rollers on longitudinal and transversal  sides (13, 14) of the cross section (1a) of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas (15) of the cross secti on (1a) of the casting strand on the transversal sides (14) of said casting strand cross section (1a) andcooling occurs exclusively by means of water jets (8) which are oriented towards said core areas (15).
