Abstract: L'invention se rapporte à une transmission pour véhicules, qui comprend une boîte de vitesses à engrenages mécaniques échelonnés (6) en face de laquelle est disposé un convertisseur de couple hydraulique (5). Le convertisseur (5) comporte une roue de turbine (19) reliée à un arbre de turbine (21). Un arbre d'entrée (25) de la boîte de vitesse (6) est relié à l'arbre de turbine (21) en mode de transmission de puissance motrice. Un frein (34) est en outre relié à l'arbre de turbine (21) ou à l'arbre d'entrée (25) de sorte que, lors du démarrage, l'arbre d'entrée (25) peut être arrêté pour permettre l'engagement d'un engrenage de démarrage sans qu'il soit nécessaire de produire une interruption de la puissance motrice au moyen d'un embrayage traditionnel. Le frein (34) est également utilisé lorsqu'on passe à la synchronisation de la boîte de vitesses (6) conjointement avec une unité de commande électrique (32) assurant la régulation du moteur. Grâce à une telle boîte de vitesses à mécanique étagée et non synchronisée, les opérations de changement de vitesses peuvent être effectuées de façon simple.

Abstract: Pour fabriquer des condensateurs céramiques multicouches, on utilise des techniques de façonnage des électrodes et de densification des couches. Les condensateurs fabriqués de cette manière ont des électrodes (12) et des couches diélectriques (14) qui sont uniformes, tout en étant plus minces et plus plates que les électrodes et les couches diélectriques fabriquées suivant les techniques utilisées jusqu'à présent. Une configuration d'électrode est imprimée sur une feuille couchée de séparation (10) puis elle est calandrée. Une couche diélectrique recouvre la configuration d'électrode puis elle est calandrée, formant ainsi une feuille verte à électrode encastrée. La feuille verte est ensuite empilée sur d'autres feuilles vertes à électrode encastrée formées de la même manière puis l'empilage est stratifié et les condensateurs bruts sont séparés de l'empilage.

Title: Cell necrosis detection through assays for spectrin and breakdown products thereof.
Inventor: LYNCH GARY S
IPC: C07K14/47
Filed: 1991-07-11
Abstract: The invention provides a method for the detection of cellular pathology by means of an immunoassay to determine the presence of stable breakdown products, termed BDP's or BDP1 and BDP2, of the cytoskeleton component spectrin. In one aspect of the invention, the components from a sample of spectrin-containing cells are physically separated, as by exposure to an electric field, in such a way that BDP and spectrin are separated. Antibodies reactive with BDP are then contacted with the separated sample, and their binding to that portion of the sample containing any BDP determined. In another aspect of the invention, an assay, such as an ELISA assay, is performed to detect total spectrin immunoreactivity as an indication of cellular death or degradation.

Abstract: All energy generation is based on conversion from one energy form to another. Until now, the primary energy sources available have been the fossil energies of coal, natural gas and mineral oil, which have been formed over millions of years on our planet Earth and may be consumed by us in a time period of only 300 to 400 years. However, the environmental stresses occurring as a result of their combustion have also unfortunately already assumed forms which increasingly call future life on earth into question. The energy problems occurring as a result of this cannot be solved worldwide using risky nuclear energy. Thus, for example, it is not possible to transport atomic electrical power (which is linked to line transmission) into countries in the third world and there may no longer be any basis of life - without energy - for their populations which in the future will represent more than half the world's population. Use of the known alternative energy sources of sun and wind is possible only with difficulty for economical reasons, since the power of these energy sources is not constant and is available only at different times, and the required storage capacities for bridging purposes are not available. As early as 1932, the world-famous physicist and Nobel Prize Winner, Prof. Dr. Werner Heisenberg predicted: "I think it will soon be possible to use magnetism as an energy source." We have not been able to implement this prediction until now, the preconditions for this finally having been created with the development of NdFeB high-energy permanent magnets. The magnetic field energy supplied by them is constantly available to everyone, everywhere and at any time. Their economical and environmentally friendly conversion into rotation or electrical energy is the sense and purpose of the invention of a magnetic field energy converter which can be used at the location where the energy is required. The invention provides a significant contribution to the worldwide solution of the energy problems and economy and ecology, with a common denominator. <IMAGE>

Abstract: A process for water softening and a household appliance or its water softening device suitable for carrying out this process are described. In order to save both water and salt, the capacity of the water softener is designed for several program sequences in the case of low hardness of the untreated water. The number of program sequences up to carrying out the next regeneration is determined as a function of the product of the quantity of water used and the water hardness to be reduced. The quantity of water is recorded by means of an impeller water meter (5) and the water hardness is recorded on an adjusting member (15). The regeneration signal (17) calculated initiates the operation. <IMAGE>

Abstract: In order to fabricate a solar cell, electrochemical etching is employed to detach from a substrate wafer (1) made of n-doped monocrystalline silicon, a self-supporting layer (7) of n-doped monocrystalline silicon. To this end, holes (4) are formed in the substrate wafer (1) by means of electrochemical etching, particular in a fluoride-containing, acidic electrolyte in which the substrate wafer (1) is connected as the anode. When the holes (4) attain a depth which essentially corresponds to the thickness of the self-supporting layer (7), the etching process parameters are changed in such a way that the self-supporting layer (7) is detached by virtue of the holes joining up. The self-supporting layer (7) is used to fabricate the solar cell. The process can be applied a number of times to the same substrate wafer (1) in order to detach a number of self-supporting layers (7).

The panel is then placed on top of the first phototool and aligned to the first phototool in the first alignment fixture using the PCR alignment mechanism. This first phototool is then affixed to the first side of the panel. The panel with the attached first phototool is then placed on the second phototool in the second alignment fixture and aligned to the second phototool using the PCR alignment mechanism.
