Abstract: An anodized aluminum support for use in a lithographic printing plate comprises a bilayered anodic surface having a total average thickness of at least 0.10 micrometers consisting essentially of oxides and phosphates of aluminum present in a coverage of greater than 100 milligrams per square meter of support. The anodic surface comprises an upper stratum comprising pores having an average diameter of 1.0 x 10⁻⁸ - 7.5 x 10⁻⁸ m and a lower stratum comprising pores having an average diameter substantially greater than the pores in the upper stratum. The support is prepared by a two stage process of anodically oxidizing at least one surface of an aluminum plate in an aqueous electrolyte comprising phosphoric acid under conditions wherein the upper stratum is formed in the first stage and the lower stratum is formed in the second stage. A lithographic printing plate comprising a radiation sensitive layer and the above-described support exhibits improved resistance to staining.

Abstract: In telecommunications services such as videotex, colours edited for the most part without taking ìnto account possible monochrome display provide only a poor quality of reproduction on monochrome monitors. To improve the contrast of monochrome reproduction , for each colour in the colour memory (17) of a conventional decoder (2), in a weighting device (19, 20) associated with the colour memory (17), the relevant colour luminosities are determined; grey values are allotted to these with intensification of the contrast, and stored in a grey-value memory (21) in the same sequence as the colours in the colour memory (17) and the grey values are retrieved, in parallel to the colours, from the grey-value memory (21) for display on a monochrome monitor (7). The method in accordance with the invention permits improved monochrome reproduction of images in telecommunications services such as videotex. <IMAGE>

Abstract: A weft feeding device, particularly for weaving looms, of the type comprising a drum (14) for winding the thread and means (30) for braking the thread which unwinds from the drum. Said means comprise an array of metallic laminas (32) arranged according to the surface of a rotational paraboloid (33) and fitted on the drum of the feeder to which it is tangent, so as to elastically engage the thread, at its own minimum-radius circumference. The paraboloid (33) has one end rigidly coupled to a fixed supporting ring (34) which encircles the drum, its other free end being subject to the action of a movable ring (37) which, when moved axially with respect to the paraboloid, varies the paraboloid's curvature in order to correspondingly vary the contact pressure of the laminas on the thread.

Abstract: For the digital received-signal-dependent adjustment of the gain factor of a digitally adjustable receiving amplifier, a circuit arrangement exhibits in each case for positive and negative received signals (ES) amplified by the gain factor a comparison device (K1/K2) the respective outputs of which are fed back via in each case one feedback circuit (RSN1/RSN2) to a comparison input of the comparison device concerned in each case. Due to the feedback circuits (RSN1/RSN2), the signal level at each of the comparison inputs exhibits different comparison values depending on the signal levels at the output of a comparison device (K1/K2). Whenever the signal level of the received signal (ES) exceeds one of the comparison values, a possibly non-linear counter device (Z1), the count of which specifies the gain, is decremented by one step. After each transmitted data block, the counter device (Z) is reset to the highest count by a retriggerable monostable multivibrator (MF) having a corresponding holding time, which monitors the data block transmission by retriggering by the received signal.

Abstract: In aeration devices for introducing gas into a liquid, there is the problem of the introduction body filled with gas being subjected to buoyancy. To eliminate this buoyancy, the introduction body is formed to be open at its free end and to be closed at its other end where it carries a fixing branch by means of which it can be connected to a gas supply distributor. The introduction body is surrounded by a perforated tubular membrane and a gas feed channel ends in the region of the membrane. 
<??>To facilitate manufacture and assembly and to reduce the consumption of material, the introduction body is designed such that its gas feed channel passes through the fixing branch as a bore which is axially blind and that at least one radial outlet is present in the region of the membrane. Preferably, a longitudinal groove which allows uniform distribution of the gas extends from the outlet of the gas feed channel to a point in front of the free end of the introduction body.
