Abstract: A method for improving the use of a transmission spectrum in a multi-sector wireless communication system includes generating a first signal, processing a first signal with a first Auto Tune Combiner, transmitting the first signal on an antenna associated with a first sector, sampling the first signal with a radio frequency test device, generating a second signal, processing the second signal with a second Auto Tune Combiner, transmitting the second signal on an antenna associated with a second sector, and sampling the second signal with the radio frequency test device.

Abstract: Process for continuously galvanizing steel sheet by passing the sheet through a bath consisting of zinc, aluminium and silicon, the aluminium content ranging from 0.05% to 0.5% by weight and the silicon content from 0.005% by weight up to saturation.There is neither formation of aluminiferous floating dross nor formation of bottom dross in such a bath.

Abstract: Finite audio and video signals are subjected to a digitizing code format and converted into blocks of audio and video words respectively. For the transmission of these blocks via a record carrier (2), for example a compact disc, the words are arranged in frames, Each frame has a frame header (8.1) and a data field (8.2). Such a data field contains information words in the form of either audio words or video words. The header indicates whether the associated data field contains audio words or video words. At least two audio signals associated with a video signal are recorded on the record carrier. An example of this is a "slide show" in which the explanatory text is available in two or more languages (e for English, f for French). The frame header of the frames containing an encoded audio signal also indicate to which one of the two or more audio signals the information words in an audio frame belong. Further, reference signals and additional frames (6)are recorded in the record carrier.

Abstract: A system is described for the line-wise compression and decompression of a video color picture. The pixels are decoded in Y-U-V bit series, thus forming code words which each contain, for example six Y-bits of different significance and also one U-bit and one V-bit. The bit series, notably the more-significant series of Y-bits (Y5 . . . Y3) are independently compressed in a compression translator so as to from length indication codes. Furthermore, at least two bit series are combined in a logic circuit (44, 46, 48), the series of combination bits then being subjected to a compression operation (50). The reverse procedure takes place upon decompression.

Abstract: A solar collector comprising a heat exchanger having a corrugated surface and an entrance window composed of evacuated transparent tubes respectively in contact with the corrugations.

Abstract: Process for the dyeing and/or finishing textile of plane articles made of synthetic or natural fibers or of mixtures of such fibers, by applying in a foamed form and at room temperature onto the goods with the acid of a gaseous propellant, a liquor containing at least one dyestuff and/or finishing agent suitable for the corresponding type of fiber, if required, chemical products necessary for their fixation as well as surface-active substances and subjecting the material thus treating for fixing the dyestuffs and/or finishing agents optionally after the decomposition or destruction of the foaming layer and if necessary by means of oxydating agents to the action of heat or subjecting it to a wet development operation by passing it through a bath consisting of an acid or an alkali, or dwelling it at room temperature or at a moderately raised temperature.

Abstract: Rapid dyeing process for piece-goods, especially knit fabrics, of synthetic fibre materials, preferably of texturized polyester fibers, by padding the material with an aqueous dyebath in a pressure vessel, which may be used both for the application and fixation of the dyestuff, at first under high-temperature (HT--) conditions and then exposing the material immediately after this operation to the action of high-pressure (HP)-- steam to fix the dyestuff completely.

Abstract: A radiological screen for placing on a patient's skin comprising a flat jacket containing a fine particulate filler and a settable resin binder, the fine particulate filler being of a material which absorbs medical radiation, and the jacket including a window to transmit such radiation through the flat jacket.
