Abstract: ABSTRACT OF THE DISCLOSURE        In an apparatus for stacking sections separated from an intermittently fed web of sheet material, successive sections are held by clamping means and transferred to the upper run of a first suction belt conveyor having suction holes which are at a spacing larger than the length of each section and attract the trailing end thereof.  A second suction belt conveyor with suction holes at the same spacing overlaps the first conveyor and takes over the sections with its lower run by attracting the leading ends.  An intermit-tently operatively stacking conveyor under the second belt conveyor has the sections deposited thereon by means for withdrawing the sections from the second belt conveyor.

Abstract: Apparatus for increasing the homogeneity of the mixture of fluids, e.g. petroleum products flowing together in a pipe. The apparatus operates by dividing the flow into multiple converging jets and comprises a tubular body (10) for insertion in the pipe. The tubular body (10) houses a cylindrical sheath (9) inside which two plates (21, 22) provided with perforations (23) define two inlet chambers (25, 26) between which the flow is distributed. The space (33) between the plates is partitioned by a plurality of partitions (36) which are substantially perpendicular to the axis of the sheath so as to constitute outlet cells in which jets from the perforations of the plates converge. Said outlet cells have openings (38) formed in the sheath for the lateral removal of the fluids which mix therein.

Abstract: Abstract of the disclosure:     .alpha.,.omega.-Bis-fluorosulfatoperfluoroalkanes, in particular 1,4-bis-fluorosulfatoperfluorobutanes, are obtained by react-ing perfluorinated .alpha.-olefins with peroxodisulfuryl difluor-ide FSO2-O-SO-2F by passing the perfluorinated .alpha.-olefins into a liquid phase containing peroxodisulfuryl difluoride, the concentration of the peroxodisulfuryl difluoride in the liquid phase being kept substantially constant within a concentration range of about 0.005 to 0.2, preferably about 0.01 to 0.1 mole/1.         The products of the process are intermediate pro-ducts, particularly in the field of polymers.  It is possible to prepare from the compounds, via several reaction stages, for example, perfluorinated vinyl ethers which still have a further functional group such as, for instance, the ester group at the other end of the molecule, which, in turn, when subjected to polymerization or copolymer-ization with other unsaturated perfluorinated compounds, such as, for example, tetrafluoroethylene, provide the parent polymers for valuable ion exchangers and the like.

Abstract: ABSTRACT OF THE DISCLOSURE An absorbent web structure is disclosed which is composed of a mixture of 5 to 50% by weight of short fibers of a thermoplastic resin rendered hydrophilic with a surface-active agent and 95 to 50% by weight of cellulosic fibers.  The thermoplastic short fibers are melt-bonded to impart self-supporting property to the web structure and are rendered hydrophilic by forming an aqueous slurry of the fibers containing a nonionic surface-active agent and then dehydrating the slurry.  The nonionic surface-active agent has an HLB value of from 2 to 20 and a melting point equal to or higher than the temperature of the slurry at the time of dehydrating treatment.  The resultant structure exhibits good mechanical strength and excellent absorbing properties when used as disposable diapers, sanitary napkins, medical sponges, wound-treating pads or towels.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention discriminates between the explosion of an ammunition round itself and the fire or explosion (e.g. a hydrocarbon fire) which may then take place in the object (e.g.a vehicle) struck by the round and initiates suppression of the latter fire or explosion only.  The vehicle carries a radiation detector which measures the ratio of the intensities of the radiation at 3.4 and 4.4 microns.  When an exploding ammunition round passes through the fuel tank entraining initially unburning hydrocarbon fuel with it, the detector measures a relatively low ratio because the unburning hydrocarbon fuel vapour between the burning round and the detector has a very intense absorption band at 3.4 microns.  Fire suppression is thus initiated, so as to suppress the hydrocarbon fire which would very shortly follow.  If the round does not strike the fuel tank, hydrocarbon fuel vapour is not present in the vicinity of the exploding ammunition round and the ratio measured by the detector is higher and explosion suppression is not initiated.

Abstract: ABSTRACT         The present invention relates to a method for cleaning gas mixtures which might contain dust from a urea plant, especially off-gases from prilling towers or granulation units.  In order to prevent precipitation and accretion in the cleaning unit, it is subjected to an aqueous washing solution to which formaldehyde is added before it is brought into contact with the gas mixture.          Formaldehyde is preferably added in the form of formaline.  The addition of formaline is regulated by the taking of pH-measurements in the washing solution; the pH being kept at pH = 6 - 8.5, preferably at pH = ca. 7, in order to obtain optimal removal of ammonia.  The method is carried out in standard scrubbers in which aqueous washing solutions can be used.
