Patent DE-4327848-A1 (DE)
Inventor: SCHWINN KLAUS
IPC: B41F33/12
Filed: 1993-08-19
Abstract: A description is given of a control unit for the electric main drive of a printing machine, the electric main drive (9) cooperating with a motor (10), a brake (11) and a tachogenerator (12). The machine control of the control unit of the printing machine is connected to a multiplicity of signal transmitters (5) (sensors). It is intended always to ensure that the printing machine does not run at too high a rotational speed, as a function of the machine condition recorded by means of the signal transmitters. According to the invention, for this purpose provision is made for the arrangement, apart from the machine control, of a monitoring unit (14) in addition, which records the switching conditions of the signal transmitters, forms therefrom the highest possible permissible rotational speed and compares this value with the actual rotational speed value supplied by the tachogenerator. As soon as the actual rotational speed value exceeds this upper limit, the electric main drive is brought to a standstill.   <IMAGE>

Patent DE-4334407-A1 (DE)
Inventor: NIEDERBERGER KARL DIPL ING
IPC: B23K26/06
Filed: 1993-10-08
Abstract: The invention relates to a process for machining a workpiece using a laser beam, in the course of which a coating which increases the absorption factor of the surface for the laser beam is applied to the workpiece surface to be machined. According to the invention, an organic, combustible gas or gas mixture is burnt, in the course of which the carbon particles produced by the combustion form the absorption-increasing coating on the workpiece surface. The combustion flame of the fuel gas or fuel-gas mixture is advantageously directed by means of a burner onto the surface to be coated. Acetylene is preferably used as the organic fuel gas. The fuel-gas mixture, apart from the organic fuel gas, advantageously receives a gas containing oxygen, such as air, air enriched with oxygen, or pure oxygen. The process according to the invention can be used especially advantageously in laser beam hardening, laser beam remelting and laser beam cutting. <IMAGE>

IPC: F16D48/06
Filed: 1994-07-14
Abstract: The invention relates to a hydraulic emergency control for a hydraulically actuated friction clutch (10) fitted between an internal combustion engine and a gearbox as part of an electro-hydraulic clutch control, in which a hydrostatic pump (1) to supply at least one working line (11) is coupled to an output shaft of the internal combustion engine. There is a throttle valve (2) in the working line (11). Up and downstream of the throttle valve there branches off at least one control line (13 and 14) and the control lines are connected to a pilot valve (4) which controls or triggers the application of pressure to the friction clutch (10).

Abstract: On propose un système de microscope ergonomique et modulaire constitué de modules de l'élément de base (1-4) assemblés et auquel d'autres modules peuvent être ajoutés directement (10) ou indirectement (11, 12; 13). Les différents modules de l'élément de base présentent intérieurement des surfaces d'arrêt de précision qui sont disposées sur des protubérances (14-16; 23) du boîtier ou des dispositifs de séparation de l'espace intérieur (17) du boîtier formant une seule pièce avec les modules de l'élément de base. Les différents composants optiques, mécaniques, électriques et/ou électroniques sont préajustés et montés définitivement sur des supports plats (24) ou en trois dimensions (56). Le système de microscope de conception modulaire objet de l'invention est réalisable sous forme de montage de modules conçu de manière à faciliter l'entretien et on évite des contrôles complexes de l'ajustage et d'alignement de l'ensemble du système. La possibilité d'ajouter facilement des modules de support équipés et définitivement montés permet d'améliorer, de reconfigurer et de déclasser rapidement l'ensemble du système intégré sans procéder à des réorganisations complexes et sans sacrifier l'ergonomie ni porter atteinte à la conception du système. Enfin le principe d'un maintien discontinu par des 'piliers' ou des 'colonnes' empêche les effets de la chaleur susceptibles de détériorer le système, tout en réduisant les utilisations de matériaux.
