Patent EP-0402830-A1 (EP)
Inventor: DIEGELMANN MICHAEL DR
IPC: B23K26/00
Filed: 1990-06-11
Abstract: For rapid soldering operations at small soldering points, it is necessary to use a fast, contact-free temperature measurement method. In principle, an infrared radiation pyrometer is suitable for this purpose. A disturbing effect in this temperature measurement method is the variation in the emission coefficients from one soldering point to another. According to the invention, this disadvantage is eliminated by calibrating the infrared radiation pyrometer in the course of each soldering operation on reaching a fixed temperature point detected by suitable measurement methods and situated within the temperature range of the method individually for the respective soldering point using previously determined calibration curves. To control the soldering point temperature in accordance with a specified temperature/time cycle, the control circuit is constructed from the infrared radiation pyrometer and the laser, whose power can be controlled. This temperature control method is insensitive to the variations in the volume of solder and the emission factor of the soldering points.

Abstract: In a two-cycle heat-insulating engine, each of combustion chambers (8) defined by the lower surface of a cylinder head (3) and a cylinder line (4) has an adiabatic structure, each of exhaust valves (2) is disposed in each exhaust port (22) formed in the cylinder head (3), an intake valve (1) for preventing the backflow of an exhaust gas is disposed in each intake port (11) formed at the lower part of a cylinder (4), each of these valves is actuated for opening and closing by electromagnetic force of each electromagnetic valve driving device (10), and a controller (15) controls the opening/closing timing of the intake and exhaust valves (1,2), the valve opening/closing time, etc, in response to detection signals from detection means (14) for detecting the operational conditions of the engine. Particularly when the engine is driven at a low number of revolution, the exhaust valve (2) is opened near the lower dead point so as to exhaust all at once the exhaust gas and to suck the intake air, to limit any thermal influences on the intake air and to prevent the drop of the intake air quantity.

Abstract: A first plurality of water filled shielding tanks (40), (50), (50') is introduced through a nuclear rector containment building hatch and placed between the stored core internals (14), (16) and the reactor vessel. A support structure (32), (34), (36) for this vertical (40) wall is previously shipped, disassembled, introduced into containment and erected between the reactor vessel and the stored internals (14), (16). A second plurality of water filled shielding tanks (50), (50') is placed on the containment building operating floor level (72) to cover the stored internals (14), (16). Once in place, the tanks allow manned activity in the reactor vessel area, such as preparations for annealing. The method includes the steps of: removing the nuclear fuel from the reactor; storing both the upper and lower internals underwater; assembling the support structure and placing same in position in the refueling canal; introducing the vertical (40) and horizontal tanks (50) through the hatch; filling the vertical shielding tanks with water and placing same in the support struc­ture; filling the horizontal shielding tanks with water and placing them above the stored internals and the vertical tanks; draining water from the refueling canal to the level of the reactor vessel flange; performing an operation requiring human intervention such as annealing; flooding the refueling canal to near the operating floor elevation; and decontaminating the tanks and support structure and removing same.

Abstract: Le moteur électrique du type à réluctance ci-décrit est pourvu d'une diode qui empêche le courant électrique à énergie magnétique produit par une première bobine d'excitation de refluer dans une source d'alimentation à courant continu. A cet effet, lorsque le flux de courant vers la première bobine d'excitation est interrompu, l'énergie stockée dans la bobine est transformée en énergie magnétique d'une deuxième bobine d'excitation qui est alimentée en courant successivement, afin de libérer rapidement de l'énergie magnétique de la première bobine d'excitation, l'énergie magnétique étant stockée rapidement dans la deuxième bobine d'excitation. En outre, l'énergie magnétique dans la première bobine d'excitation est chargée dans un condensateur de faible capacité pour produire une tension élevée. Par l'utilisation de cette tension élevée, l'énergie magnétique est stockée dans la deuxième bobine d'excitation afin de libérer et de stocker rapidement l'énergie magnétique et d'empêcher toute diminution du couple ou toute formation d'un couple antagoniste. Par conséquent, même si la tension appliquée est faible, le moteur du type à réluctance tourne à grande vitesse avec un rendement élevé. En outre, le courant d'excitation est une onde en dents de scie dont la valeur du courant dans le dernier étage est plus grande que celle dans l'étage initial, afin d'améliorer la montée du courant d'excitation.

Abstract: Bispecific molecules which react both with the high-affinity Fc gamma receptor of human effector cells and with a target cell surface antigen are disclosed. Binding of the molecules to the Fc receptors found on effector cells is not blocked by human immunoglobulin G. The molecules are useful for targeting human effector cells (e.g. macrophages) against cells bearing the target antigen. For this purpose, bispecific molecules can be constructed containing the binding region derived from an anti-Fc gamma  receptor antibody and the binding region derived from an antibody specific for the target antigen. Targeted effector cells can be used to destroy cells bearing the target cell surface antigen by cell-mediated antibody dependent cytolysis and by complement-fixation.

Abstract: A dual-stage gas bag inflator (10), operable initially, when activated, to cause the gas bag to deploy slowly and then, after a delay, to deploy rapidly, includes a housing (12) having first and second compartments (32,34) of different size separated by a bulkhead (42,58). The first compartment (32) is the smaller since it is to produce a smaller amount of gas to cause the initial slow deployment of the gas bag. A gas generant charge (96) is ignited in the first compartment, and after some delay, a gas generant charge (120) in the second compartment (34) is ignited. The delay is produced by an initiator including a squib (70), igniter material (44,98) in each of the first and second compartments, and a fuse cord (46) which is ignited by the squib. The fuse cord passes through the bulkhead and ignites all igniter materials in both inflator compartments simultaneously. The igniter material (98) in the second compartment (34) is so characterized that it burns more slowly than the igniter material (44) in the first compartment (32). When ignited, the igniter material in the first compartment burns outwardly rapidly while that in the second compartment burns outwardly relatively more slowly. As a result, the gas generant in the first compartment (32) is ignited before the gas generant in the second compartment (34).
