Abstract: 1. Support material and aluminium planographic printing plate, and process for its manufacture. 
<??>2.1 Previously, pure aluminium or manganese-containing alloys have been used as support material for planographic printing plates with a baked photo-layer. Such alloys have an essentially higher thermal stability than pure aluminium but during electro-chemical roughening in HCl or HNO3, dark surface colorations and different grain structures appear which have an adverse effect on the technical copying properties or their general ability to respond to roughening treatment. The object is to find a support material which has a pale uniform surface after the roughening treatment, a general ability to respond to roughening treatment and simutaneously high stability under baking conditions. 
<??>2.2 A material with a fine precipitation micro-structure (degree of dispersion D < 50 phases/ mu m<3>) is produced from an aluminium alloy containing 0.2-0.6% Fe, < 1% Mn, < 0.25% Si and Cu under adherence to particular conditions during the heating and shaping. The ratio of the dispersed phases AlMnSi:AlFe:AlMn lies between 1:1:2 and 1:1:3. Because of dissolved Fe and Mn as well as the fine precipitations, this material possesses a high thermal stability. Since the very fine Mn-containing phases are present only in small proportions, the surface quality necessary for planographic printing plates is achieved by the electro-chemical roughening in HCl as well as in HNO3. 
<??>2.3 Manufacture of aluminium planographic printing plates.

Abstract: Brushwear can be manufactured by melting the bristle bearer and, if appropriate, the ends of the bristles and joining them together under pressure or by inserting the bristles into an injection or foam mould for the bristle bearer and embedding them in the bristle bearer material by injection or foaming. Due to the thermal processes (heating, melting, injecting, cooling), the cycle time for these processes is very long. It can be reduced considerably by moving the tools for holding or manufacturing the bristle bearer on the one hand and clamping devices for the bristles on the other hand on closed-loop paths, transferring the clamping devices to at least one common station on the path of the tools, moving them along with the tools at least during the thermal processes and then returning them to their path of movement.

Abstract: In a nonvolatile memory of the present invention, a write circuit (10) is connected between bit lines (BL) and a write-enable voltage terminal (V pp ) and has at least two write MOS transistors (11, 12) connected to each other in a serial manner. Since at least two write MOS transistors (11, 12) are connected in a serial manner, a punch-through effect is reduced even if noises occur in a write voltage system. Even in the case where a punch-through effect occurs due to the presence of a power source and transistors (11, 12), a voltage on the bit line (BL) is reduced, thus preventing a write error from occurring relative to the memory cell transistors (MC).

Abstract: The threaded nut assembly consists of a single piece outer nut having an internal thread whose internal diameter expands conically in the direction of application of the threaded nut assembly and of an internal nut, assembled from a plurality of segments, having a corresponding conical external thread. Between the inner nut segments there are arranged compression spring devices which hold the inner nut segments apart from one another in a state where they are only partially screwed into the outer nut. In this state, the cylindrical internal thread of the inner nut is expanded such that the threaded nut assembly can be guided loosely over a screw thread into the application position. On the end face of the inner nut pointing in the direction of application there are arranged projecting spring elements which always ensure a correct thread engagement when the outer nut lays the inner nut segments against one another in the application position by means of screwing on. The threaded nut assembly can easily be moved into the application position, and detached therefrom again, even on a thread which is corroded, contaminated and bent. With hardened inner nut segments, the assembly can also be used as a thread cutting assembly. <IMAGE>

Abstract: The present invention relates to a method and an apparatus for improving the operation of a disc filter. In particular the invention relates to increasing the discharge consistency of fiber suspensions treated with disc filters in the paper and pulp industry. 
     As is known the consistency of a fiber suspension can be raised with disc filters to approx. 16 % measured on a filter disc. However, when a cake of pulp is detached from the filter surface the detaching water jet reduces the consistency to approx. 12 % measured in the pulp discharged from the thickener. In all prior art devices the detaching liquid jet is continuous and liquid is sprayed onto the filter surface even though the pulp cake already has been detached or would be detached from the filter surface by itself due to the force of gravitation. This results in unnecessary dilution of the pulp. 
     In order to avoid the above mentioned drawback a method and an apparatus (11, 12, 13, 14) have been developed with which the detaching liquid jet sprayed from a nozzle (7) is made intermittent so as not to add unnecessary liquid to the pulp. This increases the consistency of the pulp discharged from the thickener at least by 2 % which is a remarkable advantage both for the operation of the thickener itself and also for the operations subsequent to the thickening.

Abstract: For a major reduction in nitrogen oxides (NOx) from combustion gases in the combustion of fossil fuels, a type of process is proposed in which - primarily - the fuels are subjected to a stepwise, pyrolysing combustion while maintaining a low combustion temperature with reduced oxygen availability in the reaction zone, and with prolonged residence times. The reactive waste gas components thus formed increasingly - carbon monoxide (CO), hydrocarbons (CH) etc. - are then - secondarily - eliminated by catalytic oxidation within a temperature range between 800 DEG C and 200 DEG C - if appropriate with admixture of additional air - before the waste gases pass into the open.
