Abstract: Polyethylene with an average molecular weight of 500 to 10,000 is disclosed having one or several laterally bound group(s) of the formula    <IMAGE>  I  wherein R1 and R2 are the same or different and represent a lower alkyl group with 1 to 4 carbon atoms. R3 is alkyl or aryl, X is a halogen or sulfate residue and n is 2 or 3. A method for the preparation of the modified polyethylene is also disclosed. The polethylene, preferably in the form of an aqueous dispersion, is applied to glass surfaces, especially the external surface of glass containers. The modified poyethylene is especially suitable for the so-called cold-end finishing of glass. The protective layers obtained have very good smoothness values. The protective layers are resistant to the repeated action of hot aqueous washing liquors and retain their smoothness. The glass containers, provided with the protective layers, may be labelled in the usual manner.

Abstract: A body, such as a building to be heated or cooled, is surrounded by a wall structure forming two hollow spaces arranged in parallel to each other. An outer hollow space is connected to the atmosphere so that outside air can flow into the outer hollow space. A separation wall between the outer hollow and an inner hollow space has leakage paths for air to pass from the outer into the inner hollow space which is kept at a reduced pressure relative to the atmosphere to enhance an inward air flow through the leakage paths. Thus, heat passing outwardly through the wall structure heats or cools the air being evacuated from the inner hollow space, depending on the temperature gradient across the wall structure. The evacuated air passes through a heat recovery system which may be connected to a heating system of the building or to a heat storage or to the atmosphere.

Abstract: A differential pressure transducer of the capacitive type responsive to fluid pressure. The transducer includes a cylindrical body having insulating sections at either end provided with a planar end face and a concave cavity surrounded by an annular rim. The cavities communicate with each other through an internal duct in the body and are filled with a dielectric fluid. Covering each cavity and sealed to the surrounding rim is a diaphragm provided with a movable electrode which cooperates with a fixed electrode on the cavity surface to form a capacitor therewith whose value varies as a function of diaphragm deflection in response to an applied pressure. The contour of each cavity is defined by an inner concave portion whose center is aligned with the longitudinal axis of the body and whose periphery merges with an inflection zone, and an outer portion which curves from the inflection zone toward the rim to merge tangentially therewith to avoid a sharp angle at the inner edge of the rim, the inflection zone being about half the distance from the center to the rim.

Abstract: In the manufacture of packing containers by means of folding of laminate in the form of sheets or of a web of the type which comprises a relatively thick carrier layer (2) of paper or cardboard and a gas-tight, thin metal foil (5) the laminate is subjected to stresses which, particularly within folding regions comprising multiple material thicknesses, may be so strong that crack formations occur in the metal foils protecting against gas which are sensitive to tension, thus entailing the risk of the intended gas barrier characteristics of the packing container being impaired or wholly lost. To counteract this risk the packing laminate is provided with a layer (6) of ethylvinyl alcohol laminated between the metal foil (5) and the carrier layer (2) which for one thing is mechanically sufficiently durable to withstand the external stresses during the folding of the laminate, and for another has sufficiently good gas barrier properties to compensate for the loss in gas tightness which thus may arise if the integrity of the metal foil (5) is lost during manufacture of the container. Preferably the laminate is provided also with a further layer (7) of a material permeable to moisture which is laminated between the ethylvinyl alcohol layer (6) and the carrier layer (2) and which is adapted to let through moisture which from the liquid-filled inside of the container might be able to penetrate into the ethylvinyl alcohol layer (5) through such crack formations in the metal foil (5). As a result the moisture content on the ethylvinyl alcohol layer (6) can be kept at a sufficiently low level so as not to have a negative effect on the gas barrier characteristics of the ethylvinylalcohol layer (6) which otherwise diminish with increasing moisture content.

Abstract: Cylindrical support for a flexible filter candle fabric sleeve is formed as a ring of evenly spaced parallel rods round whose exterior is wound a regular wire helin. An enclosed cap on the head of the support is matched by a bottom end cap with an axial filtrate aperture. Each cap has a female thread cut in the inner face of its cylindrical section, to be engaged by the male thread formed by the terminal turns of the helix, whose wire cross-section matches the female thread cross-section, so that cap and support can be screwed together. The wall of each cap is progressively thinned in its final section away from the threaded end, providing space for a shaped sealing sleeve of plastic material e.g. polyurethane or of soft solder.

Abstract: A method for the separation and purification of an aqueous mixture of main components, namely acetic acid and formic acid and non-volatiles by extraction, uses a solvent in a circulatory system. A raffinate stream is mixed with the larger proportion of water from a solvent stripper column (11) for the removal of water. The extraction stream is introduced into a solvent distillation column (8), from which in a first step involving the use of a mixture (A) containing a larger proportion of the solvent is separated out via a header and a mixture (B) of formic acid, water and solvent is separated out via a side offtake and a mixture (C) of acetic acid and non-volatiles is also separated out. A mixture (B) is introduced into a formic acid distillation column (4) for further processing, and a mixture (C) is introduced into an acetic acid distillation column (5), and purified acetic acid is subsequently isolated in the acetic acid distillation column (5) from the header. Pure formic acid is isolated at the settling basin of the formic acid distillation column (4).

Abstract: A method is described for estimating channel impulse responses of a mobile radio channel with a broad bandwidth by a code division multiplexing method, and with a synchronization channel continuously transmitting sequences to mobile radio receivers. The sequences are provided for synchronization of each mobile radio receiver and are known to each of the mobile radio receivers. The transmitted sequences have pilot symbols for identifying the synchronization channel, and the pilot symbols are transmitted at points that are known to the receivers within a time slot. When searching for and identifying the synchronization channel, the pilot symbols and, possibly, further symbols and sequences which are known in the receivers, are evaluated to estimate the delay times and the complex amplitudes, of the mobile radio channel responses.
