It is proposed according to the invention to admix an inert gas, for example nitrogen, carbon dioxide or lower hydrocarbons, and/or an inert, volatile liquid or lower alcohols or lower hydrocarbons and/or an inert solid which has fully decomposed at the reaction temperature to form inert gases and/or volatile liquids, for example ammonium carbonate, in amounts from 0.01 to 10 % by weight with the starting mixture of the polymerisation reaction in the starting material mixing vessel directly upstream of the polymerisation reactor. The pressure of the reactor should be increased, relative to the requisite minimum pressure during the operation without additives, so that the magnitude of the material flow at the reactor outlet precisely matches the magnitude of the material flow at the reactor inlet.

Method for producing membranes coated with a catalyst on both sides

The invention relates to a method for producing membranes coated with a catalyst on both sides for electrochemical devices, with the following steps: A) producing a first semifinished product by applying a first ionomer layer onto a first support, applying an anode catalyst layer onto the first ionomer layer while using a first catalyst ink, and drying the anode catalyst layer; B) producing a second semifinished product by applying a second ionomer layer onto a second support, applying a cathode catalyst layer onto the second ionomer layer while using a second catalyst tint, and drying the cathode catalyst layer; C) removing the first and second supports from the first or second ionomer layer and, joining the first semifinished product to the second semifinished product by joining the first ionomer layer to the second ionomer layer.

Communication device and method for radio communication

A communication device is provided that includes a baseband circuit and a transmitter configured to transmit a first signal and a projected signal. The baseband circuit is configured to determine the projected signal based on an estimated signal state information such that an energy of a shaped projected signal is smaller than an energy of a shaped signal. The estimated signal state information is an estimate of a signal state information based on the first signal and a received signal that is received by a receiver of the second communication device. The shaped projected signal is the projected signal received by the receiver of the second communication device and filtered by a filter of the second communication device. The shaped signal is the received signal filtered by the filter of the second communication device.

Indirect moistening assembly for dry paper, carton or tissue paper web has steam box of water spray extending full width of web

A paper web moistening assembly is located after a drying station. The dry web passes around a rotating moistening cylinder (4) whose temperature is lower than that of the web. Prior to contact with the steam box (6) the web is coated with a water film (9). The moistening cylinder has a hydrophilic contact zone with an engraved water drainage interface. The moistening station is a steam box (6) or water spray extending the full width of the web.

Pressure-medium actuated brake system

A pressure-medium actuated brake system, especially an electro-pneumatic multi-circuit brake system for commercial vehicles, with at least one pressure control valve (17) arranged in an air brake circuit, is described, the valve inlet (41) of which is connected to a pressure medium reservoir (11) and the valve outlet (42) of which to at least one wheel brake cylinder. The pressure control valve (17) also has at least one pressure-medium control inlet (59), to which an emergency brake valve (34), connected to the compressed air reservoir (11), is connected. The pressure control valve (17) and emergency brake valve (34) are so matched to one another in their design that when the emergency brake valve (34) is actuated the pressure control valve (17) assumes a position connecting a valve inlet (41) and valve outlet (42). …<IMAGE>…

Process to apply a liquid or paste coating to the surface of a wet paper or cardboard web

To apply a liquid or paste coating to the surface of a moving web (2), of paper or cardboard, one fourdrinier of the two fourdriniers (1,3) flanking the web is removed from at least one web surface directly before the coating is applied. Directly after coating, a fourdrinier is returned to the coated side of the web. The replacement fourdrinier is identical to the detached fourdrinier. The fourdrinier is detached from the web (2) surface and returned to it by an assembly of preferably three deflection rollers (10-15). The fourdrinier movements from and back to the web surfaces are effected on both sides of the web, before and after the coating applicators (6,8). The coating medium is in a different composition for each side of the web. The web is supported during surface coating. At least one coating is an application dye with or without a filling material, and at least one coating is of starch. An Independent claim is included for a papermaking machine with at least one deflection assembly to detach a fourdrinier (1,3) from the web (2) surface, directly in front of a coating applicator (6,8), and return the fourdrinier after the applicator to the coated surface of the web. The fourdrinier returned to the coated surface of the web is identical to or different from the fourdrinier detached from the web in front of the coating applicator. The fourdrinier applied to the coated web surface can have a finer pore structure than the fourdrinier lifted away from the web in front of the coating applicator. A web support, in the form of suction boxes (7,9), is at the side of the web (2) away from the coating applicators (6,8). The coating applicator (6,8) is a doctor unit, with a doctor blade or roller, or it is a spray.
