Abstract: The present invention relates to a gas discharge lamp for hardening materials hardenable by UV light comprising a tube (4) filled with filler gas (3) for generating a gas discharge for the emission of electromagnetic radiation to below 200 nm, with the employment of an inert gas facility for providing an inert gas and delivery of the inert gas to the surface of the material to be hardened. Further, the present invention relates to a system and a method for hardening materials hardenable by UV light, and to a material hardened by the method in accordance with the invention.

Abstract: An improved axle beam and self-contained drum brake assembly, particularly for heavy duty trucks, is disclosed. The assembly includes a brake spider and actuating members mounted thereto via a mounting assembly comprising a mounting sleeve attached to the brake spider by means of a second mounting bracket, and a first mounting bracket securing a pneumatic brake actuator cylinder to the mounting sleeve. A brake actuating camshaft is positioned and rotationally supported therewithin. The disclosed brake assembly allows for numerous variations of axle beam and suspension arrangements.

Abstract: The present invention pertains to a processing station (1) for workpieces, especially vehicle bodies (2), in a transfer line (3). Changeable clamping frames (5, 6) are kept ready in magazines (7, 8), and the magazines (7, 8) are arranged on both sides in front of and/or behind the work station (29) in relation to the direction of the transfer line (3). At least one processing device (4) is arranged at the work station (29) on the side of the transfer line (3). The magazines (7, 8) are preferably designed as rotatable and upright drum magazines and are connected in pairs by a common transport device (10). The old clamping frame (5) can thus be moved from the work station (29) into one magazine (7, 8) and a new clamping frame (6) can at the same time be brought to the work station (29) by one movement.

Abstract: The present invention provides a process for cross-linking non-polar polymers in a high-frequency electric alternating field with the use of a peroxide as cross-linking agent, wherein the cross-linking agent used is a peroxide of the general formula: ##STR1## in which R.sup.1 is a hydrogen atom, an alkyl radical containing up to 4 carbon atoms or a phenyl radical optionally substituted by halogen atoms or alkyl radicals containing up to 4 carbon atoms;R.sup.2, R.sup.3, R.sup.4 and R.sup.5, which can be the same or different, are hydrogen atoms or, together with the carbon atoms to which they are attached, represent o-phenylene radicals;A is a straight-chained or branched alkylene radical containing up to 5 carbon atoms or a straight-chained or branched alkylene radical containing up to 5 carbon atoms or a phenylene radical and;R.sup.6 is a hydrogen atom or a radical of the general formula ##STR2## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are identified as above.

Abstract: A filter apparatus comprising filter elements and reverse-flow cleaning means for the gas filter elements. The gas filter elements can be filter bags, filter pouches or filter cells. The reverse-flow means comprises a two-stage injector for drawing-in clean gas in two stages associated with each filter element by pulses of scavenging gas which are injected into the filter element in the direction opposite that of the filter flow. In order that large quantities of scavenging air for the cleaning of the filter elements can be produced in a small space, the first stage is formed as a Coanda annular slot injector and the second stage is formed as an inlet nozzle. The highest possible kinetic energy in the outlet jet of the first stage is obtained by forming the injector tube of this stage as a cylindrical outlet tube.

Abstract: A method and apparatus are disclosed for the emergency control of model aircraft. The incoming signals to the model are screened and, if missing or outside acceptable limits, the screened signals are replaced with a sequence of preprogrammed emergency signals which control the model into an emergency procedure.

Abstract: The invention relates to a magnetic disc for track adjustment and amplitude control having at least one control track with magnetic control signals, this track being arranged in the central region of the recording area, and the control signals consisting of two different signals. The invention also relates to the geometric arrangement of the control signals in the track, their number, their amplitude, their frequency and their duration.
