    摘要: To isolate shock deburring valve units in a shock deburring system and prevent back-flash or backfire during operation of the deburring system, and absorb thermal and pressure shocks exerted against the deburring valves--which, in operation, are closed--at least one of the valves is separated from the mixing chamber where the explosive force arises by a connecting line which is long enough and encloses therein a volume of the respective gas which is such that under the pressure due to an explosion in the mixing chamber, the gas can compress within the respective connecting line to thermally isolate the valve from the chamber and provide a compressible thermally isolating shock cushion for the respective valve to protect the valve against thermal damage and shock. Preferably, the valve is constructed to use a resiliently deformable sealing material between a portion of the valve bore and the valve sleeve in which a cylindrical insert is located so that pressure transferred to the closed valve will result in inwardly directed radial pressure upon deformation of the deformable substance over the sleeve and against the cylindrical projection to provide a reliable seal and, should damage to the sealing material result, permit self-healing of the respective valve.

    摘要: The valve for use in thermal shock deburring apparatus, in which oxygen and hydrogen are combined under explosive conditions, and which provides reliable shut-off of the respective gas component being supplied to an explosion jet chamber, and which prevents backfire or backflash, is enclosed in a housing formed with a bore, preferably cylindrical, in which an insert sleeve is located; a resiliently deformable sealing material such as, for example, Teflon, is located between a portion of the bore and the sleeve. A valve plunger is shaped to engage the resiliently deformable material to seat thereagainst; the plunger is formed with a projecting cylindrical portion fitting into the sleeve so that, upon engagement of the plunger with the resiliently deformable substance, inwardly directed radial pressure will additionally be exerted upon deformation of the substance over the sleeve against the projection, to provide a reliable seal and, if contamination should damage the sealing material, resilient deformation permits self-healing thereof.

    摘要: In order to heat-up a commodity to be heated or a substrate to be coated, uniformly in a vacuum chamber or in a recipient, by means of a gas discharge or low voltage arc discharge, at least one locally variable and/or displaceable magnetic field is maintained in the vacuum chamber or in the recipient at least during the heating up step. Preferably, at least two magnet fields are maintained which partially overlap and which alternatingly are operated stronger or weaker, to therewith locally influence the current density in the vacuum chamber or recipient, in order to produce along the substrate or the commodity to be heated, alternatingly a stronger or less strong heating.

    摘要: A method and apparatus centers of an electron beam (3) in a surface coating installation with movable substrates. A rotating magnetic field is superimposed on a main magnetic field which serves to guide and focus the electron beam. A focal spot of the electron beam is thus caused to rotate about a theoretical axis (17) of the electron beam (3) and the beam sweeps the entire surface (32) of a raw material source (4). Changes in the consumption of reactive gas supplied to the installation are measured by a flowmeter (21). Through a control unit (20) connected to the flowmeter, stationary magnetic fields are superimposed on the rotating magnetic field and the electron beam (3) is aimed at the center of the surface (32) of the raw material source (4) as a function of variations in the reactive gas flow.
