Abstract: The process relates to the assemblage of self-supporting ceiling panels (1) in ships or buildings. Supporting profiles (5) provided with an upwards directed longitudinal flange (17) are applied along the upper part of two opposite walls (3). Several runners (6) having a lower, horizontally projecting tongue (10), a downwards directed flange (11) placed at the back and possibly an upper, horizontally projecting tongue (12) are hung up preferably opposite to each other in the flanges (17) of the supporting profiles (5) by means of the flanges (11), whereby the runners (6) can be pushed along the profiles (5). A panel (1) is placed on the tongues (10) of a first set of runners (6), whereupon the next panel (1 ) is placed on the tongues (10) of the next set of runners (6 ) and pushed together with the previous panel and so on until the whole ceiling has been installed.

Abstract: The deposition of pitch on the machinery used in the pulping and papermaking processes and in the final paper produced in the papermaking process is prevented by adding an effective amount of a water-soluble zirconium (IV) compound to the aqueous system of a pulping and/or papermaking process to prevent the deposition of pitch on the machinery and in the final paper. The addition of an effective amount of a water-soluble zirconium (IV) compound to the aqueous system of the pulping and papermaking process also removes pitch deposits from the machinery used in the pulping and papermaking processes.

Abstract: A planar doped barrier structure for use, for example, in a Gunn oscillator, comprises, in a stack, a first doped semiconductor layer (3) of a first conductivity type, an intermediate layer (4) of semiconductor material, a doped semiconductor layer (5) of the other conductivity type which is substantially fully depleted, and a second doped semiconductor layer (7) of the first conductivity type. The doping density of the first doped semiconductor layer is different from that of the second doped semiconductor layer, so that an asymmetrical device is produced in which the potential barrier height which is encountered, for zero bias, in one direction across the barrier is different from that encountered in the opposite direction. This allows the forward characteristics of a diode structure to be significantly improved, without necessarily changing the reverse characteristic. A further intermediate layer (6) may be formed between the layer (5) of other conductivity type and the second doped semiconductor layer (7). The intermediate layer or layers may be substantially undoped, or may be slightly doped to be of the first conductivity type, in order to reduce the resistance of the device.

Abstract: This invention relates to organopolysiloxane compositions and, more particularly, to such compositions that can be cured to produce pressure-sensitive adhesives. 
     While the hydrosilation reaction of alkenylsiloxanes with hydrosilanes in the presence of a suitable catalyst has been used to prepare potting, molding, and elastomeric products as well as materials useful for providing substrates with a release surface, the reaction has not been used to a great extent to provide pressure-sensitve adhesives. 
     The present invention provides pressure-sensitive adhesive composition comprising (a) a benzene soluble, resinous copolymer, (b) a diorganoalkenylsiloxy endblocked polydiorganosiloxane, (c) a diorganohydrogensiloxy endblocked polydiorganosiloxane, (d) a crosslinking agent, and (e) a hydrosilation catalyst in an amount sufficient to effect curing of the composition. The major advantage of the present invention is that solvent need not be used to apply the composition. This non-use of solvent results in savings of material, time, and energy, and reduction in health and safety hazards.

Abstract: The method and apparatus for measuring the voltage between two objects utilizing an electro-optic crystal (3) exhibiting birefringence in two axes (slow and fast) mutually orthogonal to an optic axis (Z) extending between the two objects. Two collimated light beams (5, 13) polarized at an angle to the slow and fast axes is passed through the crystal parallel to the optic axis with one of the collimated light beams retarded relative to the other by about a quarter (¼) wave. The two beams emerging from the crystal are passed through a polarizer (9) and converted to phase shifted electrical signals (e₁ , e₂) by photo diodes (49) in electric circuits (43) which regulate the sources (23, 25) of the light beams to maintain the peak magnitudes of the two electric signals constant and equal. 
     A stairstep output waveform representative of the measured waveform is generated in a digital computer (77) from a bidirectional cumulative count (n) of zero crossings and relative phase of the two electric signals.

Abstract: An oxydation or reduction process of organic substrates by indirect eletrochemical route is described. In the oxidation, the electrochemical step yields an higher valence metal oxide, such as RuO₂, NiOOH applied on an inert conductive carrier. The higher metal supported metal oxide is released from the aqueous electrolyte and it is then contacted with the pure organic phase to be transformed. The metal oxide is then reduced to a lower valence and it is subjected again to electrochemical oxydation after having being purified from the organic residues. The process comprises a cyclic repetition of the above steps. The reduction process of organic substrates is similar and is carried out by means of hydrogen from hydrides formed by cathodic charge by means of electrolysis of an aqueous solution.

Abstract: The combustion device consists of a cylindrical container (1), in which bundles of heat-exchange pipes (7) are arranged in an annular chamber (18). While the media flow to be treated is supplied through the heat-exchange pipes (7) to a burner (13), the discharge of the heated treated media flow takes place over the heat-exchange pipes (7) and flows around these. As a result, the heat-exchange pipes (7) are exposed to changes in length which are compensated by the heat-echange pipes (7) being provided in the inflow-side end region with Z-shaped or S-shaped double bends (8-8). Connecting pieces (9) between the double bends (8-8) are inclined tangentially to a circle, the central point of which lies in the central axis of the container (1). As a result, the connecting pieces (9) can be dimensioned comparatively long, as a result of which particularly large changes in length of the heat-exchange pipes (7) can be compensated in a very elastic manner.
