Abstract: ABSTRACT OF THE DISCLOSURE   An improved process is provided herein for producing a compound of the formula I                         I in which R1 stands for hydrogen, alkyl, alkoxy, halogen, or trifluoromethyl, and R2 stands for a carboxy group or for a protected carboxy group, in particular an esterified carboxy group;  or a salt thereof in case R2 is a carboxy group or R2 contains a basic or acidic group, the compounds of formula I, depending upon the meanings of R1 and R2, being of value at .beta.-lactamase inhibitors and/or antibiotics, and/or as intermediates in the production of antibiotics and/or .beta.-lactamase inhibitors.  According to the improved process, certain penicillanic acid derivatives or their sulfoxides are oxidized to the corresponding sulphones with hydrogen peroxide in the presence of a tungsten or molybdenum catalyst.  This new process eliminates secondary degradative oxidative side reactions and simplifies the isolation and purification of the product, thus providing high yields and thereby being particularly suited for large scale produc-tion.

Abstract: ABSTRACT OF THE DISCLOSURE            To produce microdroplets of fluid a liquid jet is injected centrally into an atomizer chamber with the formation of a spray cone and there it is acted upon by an outer spiral-shaped gas flow.  To further reduce the size of the droplets, same are introduced into a transport or reaction chamber of short structural length and carried through same by a further spiral-shaped gas flow.  Preferably, the transport or reaction chamber is lined by a pot-shaped container, the fluid droplets entering the transport or reaction chamber at the front side opposite an open end thereof.  The method or the arrangement for applying the method is particularly suitable for a practically soot free combustion of combustible fluids, particularly oil.          BACKGROUND OF THE INVENTION          The invention concerns a method and a device for producing microdroplets of fluid.          In a great number of chemical or physical processes, particularly in drying and combustion processes, it is  great import-ance to obtain reactive microdroplets of fluid.  Ordinarily, a fluid

Abstract: Abstract A process for producing regenerated cellulosic articles from cellulose which has been dissolved in a mixture of dimethyl sulfoxide (DMSO) and formaldehyde, and for recovering the solvent chemicals.  The DMSO/formaldehyde solution of cellu-lose is brought into contact with an aqueous solution, the pH of which is at least 9 and the adjustment of pH has been carried out by means of a base or an alkaline salt which does not react with formaldehyde and the content of which is at most 0.1 % by weight, so that the product is coagulated and regenerated in the desired form, such as fibres, films or shaped articles.  The coagulation solution is evaporated in one stage or plurality of stages so that the DMSO and form-aldehyde of the cellulose solution remain in the evaporation residue.  The evaporation residue is recycled for the product-ion of cellulose solution, purified, if so required.

Abstract: ABSTRACT OF THE DISCLOSURE    The tamping machine comprises, for each row of rails a tamping unit which is movable in the transverse direction of the track in order to tamp the track switches.  The controlled transverse mobility of each tamping unit, to the right and left of the line of rails, is obtained by the combination of a lever manual control member and an automatic control circuit which is controlled by two amplitude limiters.          A switch makes it possible to change from manual to automatic and vice-versa.  By presetting the amplitude limiter at a value corresponding to a transverse position of the tamping unit which is repeated several times along the track switch, the positioning of the tamping unit is obtained by simple actuation of the switch upon arrival at these recurrent positions.

Abstract: ABSTRACT OF THE DISCLOSURE               METHOD FOR ELECTRON BEAM WELDING      This invention concerns a process of welding by an electron beam.  The process is one in which the beam is rapidly deflected from point to point of a predetermined matrix of spots over which the beam rests for predetermined lengths of time in order to produce a predetermined distri-bution of energy over a defined area along the surface of the material being welded along a seam formed at the adja-cent edges of workpieces.  The length of time the beam is maintained at each position and the total beam power may be varied from spot to spot in order to produce a desired distribution of energy over a given area.  This process is useful to avoid defects in partial penetration welds and in the welding of joints in which the gap between the edges to be welded may approach the diameter of the electron beam. The method is also useful in avoiding defects which may normally occur at the beginning and end of a weld seam.

Abstract: ABSTRACT OF THE DISCLOSURE     The process and the apparatus for deburring moulded parts produced by pressing especially moulded parts of ligno-cellulose fibre mats.  A small circumferential zone of the fibre mat between the edge contour of the moulded part to be deburred and the edge of the waste shoulder is thermally decom-posed during pressing.  In the decomposition zone the thermally decomposed portion of the fibre mat is removed from the edge contour of the moulded part or removing the moulded part from the press tools.  The decomposition zone is limited by a cir-cumferential groove shaped chamber provided in one of the press tools.  The portion of the fibre mat enclosed in the chamber is substantially uncompressed and the chamber is provided with means which can be of various types for the thermal decomposition.          The means causes carbonization of the material of the decomposi-tion zone which facilitates the removal of the waste shoulder from the moulded part so that additional hand treatment is unnecessary.
