Abstract: A process and apparatus for coating the interior of a fiber-reinforced tube formed of cellulose hydrate in which a tube filled with a coating liquid is passed through a special conveying and pumping device which also serves to replenish the coating liquid. Above the level of the coating liquid, the tube is inflated with a support gas and is gradually flattened. The flattened tube then travels through a metering device made up of wipers in the form of doctor blades or rollers, which retain the major quantity of the coating liquid which is present on the inside surface of the tubing so that a thin, uniform film of the coating liquid is formed. The tubing is thereafter dried to remove the volatile constituents of the coating liquid, and is subsequently wound up.

Abstract: To produce a sheet used as an electric insulation material, a pasty beading (33) is continuously formed from a mixture of hardenable resin and muscovite- or phlogoptit-based mica powder preferably of electric quality. This beading passes into a calender or a band press which, by decreasing the thickness thereof, transforms it into a thin layer. The platelet-shaped mica particles are arranged in parallel to the layer plane. The building (33) may also contain, in addition to mica powder, other thinner and/or reinforcing materials. The formation of the building (33) is preferably carried out by means of an extrusion press wherein the resin, optionally liquid and without solvent, is mixed to the mica powder and a latent hardener (31) is then added to said mixture. Appropriately during the formation of the thin layer between two separation sheets (28), the thin layer may be directly bound to a carrier material band (29). When fabricating insulations for coils of electric machines by using said sheet, the synthetic resin contained in said sheet is allowed to harden.

Abstract: Testing of interface lines (14) interconnecting a first circuit (10) to a second circuit. When an abnormal circuit condition affects the interface lines, such as an open circuit or a short circuit condition, the operation of the first and second circuit is detrimentally affected. The present invention determines the existence of abnormal circuit conditions in one or more lines of a group of interface lines without the utilization of redundant duplex lines to perform the determination. The interface lines are subdivided into a first group (14a), which are used when the apparatus of the present invention is being used to locate abnormal circuit conditions, and a second group (14b), which is not used when the apparatus of the present invention is being used to locate abnormal circuit conditions. Each line of the first group is connected to a corresponding input terminal of a first exclusive OR gate (16) and a second exclusive OR gate (18) at an input side and an output side, respectively. The first and second OR gates are input to a matching circuit (20), an output signal therefrom indicating the existence of an abnormal circuit condition in the first group of lines. As a result, since the lines of the first group are used when the apparatus of the present invention is being used to locate abnormal circuit conditions, each line of the first group is tested individually for the presence of an abnormal circuit condition. However, since the lines of the second group are not used when the apparatus of the present invention is locating abnormal circuit conditions, the lines of the second group are tested, collectively, as a group, for the presence of an abnormal circuit condition. One line (11) of the first group is connected to an input side of the second group. The output side of the second group is connected to an additional input terminal of the second exclusive OR gate. An output signal from the matching circuit indicates the existence of an abnormal circuit condition in at least one line of either one or both of the first and second group of lines.

Abstract: In a process for purifying and deaerating the feed water line in the circulation system of a power-generating plant heated by nuclear power, the following steps are carried out in order to solve acute problems of steam-generator corrosion: (a) when the preheater train is filled, with the steam-generator isolating valve (40) closed, the condensate flows several times via a recirculation line (37, 52, 53) back to the condensate-collecting vessel (6) and to the condensate purification apparatus (9); (b) below the water level (7) in the condensate-collecting vessel (6), a deaerating medium (37,38,39) is introduced into the condensate via spray nozzles, rises in the condensate and forms in the deaerating chamber (44), as result of displacement of the air present in its, a cushion which is conducive to oxygen deaerating; (c) the steam produced during deaerating is precipitated in an additional condenser (48) which is located in the venting line upstream of the vacuum pump (47) and which is subjected to a secondary cooling water; and (d) following the start of steam generation and during the low-load period, subsequent deaerating is carried out by means of steam in the collecting vessel of the condenser. As a result, it is possible to provide purified and deaerated feed water over the entire operating range and to reduce to a minimum the deaerating time before the plant is started.

Abstract: In such bodies, in particular resonance bodies for musical instruments and the like, there is the problem of being able to adjust the spectrum of natural frequencies in the sense of an accentuation or attenuation or of a balanced variation in certain specifiable frequency ranges. In this connection, the vibration behaviour of the solid body is governed by the spatial, i.e. one- to three-dimensional distribution of the vibration parameters, especially the elastic deformation rigidity and the density or mass per unit area, based on, for example, the surface of the vibrating body. To solve the problem, it is proposed to arrange the spacial distribution of the vibration parameters in accordance with a subdivision (G, G1) having a plurality of superimposed series (R, R1, R2 ...) of regions of increased or reduced deformation rigidity, vibrating mass, vibration damping, surface curvature or bulging, or the like. At the same time, these regions are arranged essentially in an equidistant manner within a series. As an alternative to this or in conjunction with it, a subdivision with regions of the above type is suitable, the distances of the regions from one another being in the ratio of the members of a harmonic series. <IMAGE>
