Abstract: A braking arrangement for rotatably supporting an element rotatable about an axis such as a control wheel, rotary control knob or the like, for example for a vehicle fresh air nozzle, has a plug-shaped casing with an end portion and a peripherally extending flange extending away from the end portion and having a circular external peripheral surface. The external surface of the flange forms a rotary mounting surface for the rotatable element. The flange encloses a central guide space for two braking members which have braking portions facing diametrally away from each other. The braking portions extend through transverse holes in the flange. The two braking members are urged away from each other by a spring disposed therebetween.

Abstract: A method and apparatus for fitting a printing plate to a plate cylinder where the printing plate is bent into a circular shape and fixed in this form by leading and trailing legs of the plate being firmly connected to each other. The printing plate shaped in this way is subsequently axially pushed onto the plate cylinder from the free side of the plate cylinder.

Abstract: A process for producing a printing form on a form cylinder, which process operates reliably even in the case of large form cylinders and high laser powers, contains the process steps of drawing a blown film tube onto the form cylinder, transferring surface elements of the tubular film, in accordance with an image, as a result of heating by a laser beam, and removing the blown film tube from the form cylinder.

Abstract: A method and an apparatus for producing steels with predominantly high Cr content and/or ferro-alloys, wherein the metal charge is melted in a melting crucible, is alloyed, refined and reduced, and wherein process gases are simultaneously supplied through bottom nozzles. A melting crucible is used with a specific reaction volume of 0.4 to 1.5 m.sup.3 /t steel and the injection rates of the process gases are controlled in the range of 0.1 to 3.0 N m.sup.3 /t/min. The solid charge material is melted by an electric arc and air/nitrogen are injected simultaneously and, after forming a liquid sump, a gas mixture of oxygen and inert gas is injected. After adding slag-forming constituents and alloying agents, the oxygen throughput is increased and the power of the electric arc is reduced accordingly. The oxygen throughput is reduced in relation to the inert gas during refining and decarburization takes place as a result of increasing the electric arc with low chromium slag formation.

Abstract: A web-fed rotary printing machine having a plurality of directly adjacent printing units. Each of the printing units has only one side wall, in which the printing group cylinders are float mounted. The printing units are arranged in-line with no working space between them.

Abstract: A parabolic antenna for measuring the level in containers is proposed, a transmitted pulse from a transmitting and receiving device being focused via the parabolic antenna and directed onto the surface of a filled material whose level is to be determined, and the pulse reflected at the surface of the filled material being received again by the receiving device via the parabolic antenna. For the purpose of introducing the measuring instrument through an opening in the container, the parabolic antenna can be folded and unfolded by being positively moved.

Abstract: In a high-pressure cleaning apparatus comprising an electric motor arranged in a housing, a high-pressure pump arranged in a housing with at least one piston entering a pump chamber in a sealed manner, and a swash plate carried by a motor shaft protruding from the housing of the electric motor, with the piston or pistons of the high-pressure pump resting in a resilient manner against the swash plate, in order to achieve electrical insulation in the region of the swash plate drive, it is proposed that the transition from the motor shaft via the swash plate to the piston or pistons be electrically interrupted by an electrically insulating material being interposed therebetween.

Abstract: A printing machine, having side walls and at least one form cylinder with an outer cylindrical surface carrying a removable sleeve-shaped printing form, the form cylinder having journals and being removably mounted in the side walls. A bearing rotatably supports the journals in the sidewalls and at least one of the side walls has an opening. A transport device moves the form cylinder back and forth through the opening in the side wall so that the sleeve of the form cylinder removed from the printing machine can be exchanged for a replacement sleeve and the form cylinder with the replacement sleeve can be moved back into the printing machine.

The plastic half is latched into position with the metal half whereby the metal half has a threaded surface on the lower rim of its external surface when assembled.

Abstract: A diagnostic method for motor vehicles with a diagnostic device for checking electronically controlled systems, in which a fault memory provided in an electronic control device is interrogated and in which test steps to be performed in accordance with the information in the fault memory are prescribed. The test steps performed in response to the prescribed test steps are recorded in the electronic control device.

Abstract: A sanitary water valve having control elements consisting of at least two discs. The first disc is arranged immovably and constitutes the valve seat disc and the second disc, which constitutes the control disc, is arranged movably on the first disc and has a surface conduit for deflection functions which can simultaneously be made to overlap the inflow apertures and outflow aperture on the first disc. The second disc includes one or more depressions which substantially reduce the actuation forces required to open the water valve and as a result, operating efficiency is considerably enhanced.

Abstract: A communication process and accompanying apparatus for enabling communication between different areas of the printing process, e.g. between the preliminary printing stage and the printing press, in either direction so that data for regulating the printing press can be obtained from data which does not depend on the type of printing press and the data to be printed which are received from the preliminary printing stage can be influenced by the printing press itself. The apparatus has a communication structure formed by a central main data processing station, with which a plurality of printing units of the printing press are interlinked for joint preparation of a job, and a decentralized data processing substation for each area of the printing process which can be connected in turn with the main data processing station. The connection between the substations and the main station is formed by device-independent interfaces which allow data to be transferred in either direction.

Abstract: An arrangement for operating an arc furnace with two vessels for making steel. Enough liquid raw iron is added to account for 70% of the total starting metallurgicals. The supply of electricity to one of the vessels is discontinued but not to the other vessel. The injection of oxygen through a lance accompanied by the addition of sponge or coolant and lime, is carried out in one vessel while an electric-arc furnace phase is carried out in the other vessel, whereby additional sponge or coolant is melted with less oxygen and additional lime or coal is added. Electrodes are mounted on an arm and can be pivoted over either vessel as desired.

Abstract: To compensate for tolerances and variations in tolerances in a recording system in which a thermal transfer foil is passed between a image recording element (3) and a printing form carrier (1), the thermal transfer foil, for example of a polyester base (9), has an intermediate layer (8) applied thereto on which a meltable substance layer (7, 7'), for example on a polyethylene base, is located. The intermediate layer (8) is thermally volume expandable, by including therein either a foaming agent or moisture or other gas which, upon application of heat, causes foaming or the formation of gas or steam bubbles to expand its volume. Tolerances 6 of up to about 1 mm, thus, can be compensated and pressure variations and surface variations between the thermal image recording element (3) and the form carrier (1) are no longer critical.
