Abstract: PHT 79-411                 11                   15.8.1980 ABSTRACT: Optical fibre switch.           A switch for making and breaking optical connect-ions of optical fibres, by connecting one fibre to a fibre of a group of fibres. The coupling of fibres is realized in a V-groove in a first holder. The switch comprises two holders, each of which comprises a gear ring; these rings are made to engage by means of a helical spring. The first holder accommodates several fibres which are equidistantly distributed over its circumference. A coupling between two fibres is broken by pulling the holders apart(against the force of the spring). by subsequently rotating the holders and moving the holders towards each other again, a coupling between the fibre on the second holder and a further fibre on the first holder is realized. The second holder comprises a positioning ring which provides coarse orientation of the holders with respect to each other. The two gear rings provide exact final positioning of the holders.

Abstract: ABSTRACT           The nitrogen content of low carbon steel made by the basic oxygen process is minimized by:          (a) introducing nitrogen-free fluid into the vessel before the nitrogen content of the melt has reached its minimum level, (b) adjusting the flow rate of the nitrogen-free fluid to maintain total off-gas flow rate at least equal to that which would have been produced without the nitrogen-free fluid at the time in the refining process when the nitrogen content of the melt reached its minimum level, and (c) the injection of nitrogen-free fluid throughout the remainder of the oxygen blow.          A preferred additional or alternatively separate step involves minimizing the nitrogen content of BOP steel by purging the vessel headspace with a nitrogen-free fluid prior to reblows.     This is a divisional application of applicants' copending patent application, Application No. 288,670, filed October 11, 1977, having a priority date of January 11, 1977.

Abstract: PHN 9663                 10                     29.8.80 ABSTRACT: Lamp having a lamp vessel made of quartz glass, quartz glass and method of preparing quartz glass.     A quartz glass lamp vessel 1 or 21 is used in many types of lamps. Sometimes it is expedient to absorb a certain portion of the emission spectrum. In accordance with the prior art this is possible by including rare earth metal oxides in the quartz glass.          The solubility of rare earth metal oxides in quartz glass is, however, limited.          According to the invention, quartz glass is us-ed which contains an alkali metal oxide and, optionally, an alkaline earth metal oxide, in addition to a rare earth metal oxide. The alkali metal oxide increases the solubility of the rare earth metal oxide, so that rare earth metal oxides can be used in larger concentrations. This results in glasses which have a higher degree of ab-sorption, from which lamp vessels can be produced.          Fig. 6 to be included.

Abstract: ABSTRACT     A catalytic body which is substantially amor-phous is formed from at least two materials vacuum deposited on a cool substrate or sprayed on a cool surface to provide a local order non-equilibrium structural configuration.  The amorphous body comprises a composition of at least one metal and a second component which maintains the amorphous character of the composition.  The body has an increased number and desired type of catalytically active sites.  In most applications, the composi-tion includes at least initially a component which is removed by leaching or vaporization to leave a rough surface with a large surface to volume ratio.          The resulting composition is sometimes annealed to relax or modify the local structure thereof to provide a more reactive structural configuration.          In an electrode form of the invention, the cata-lytic body is highly conductive, resistant to corrosion and degradation under current reversal and has low overvoltage characteristics when used in electrochemical cells.

Abstract: ABSTRACT OF THE DISCLOSURE A molding machine for die casting, injection molding, and other similar processes, comprises a base shaped to support thereon a two-part die, and a ram for converging and diverging the die halves between open and closed positions.  A pair of clamping frames are pivotally mounted on one end of the base, and include a closed border shaped to surround or receive therein side portions of the die halves.  The clamping frames are laterally pivoted between a fanned-apart or open position wherein the die can be freely lifted off of the base, and a folded or closed position wherein the frame borders surround the die side portions and capture the same between the ends of the frames.  In the closed position, retractable compression columns extend between the die and one end of the frames to positively lock the die halves in the closed position, whereby die separation forces developed during injection of the die are resisted substantially solely by the clamp-ing frames.

The polymeric disper-sant additives are ionie polymers which comprise a back-bone substantially soluble in the fuel or lubricang and pendant ionie groups which are sulfonic acid groups which may be neutralized with an ammonium eation or an amine. Polymerie dispersant additives of this type may be made which are partieularly useful in crankcase lubricating oils for imparting viseosity improvement, varnish inhibi-tion, oxidation inhibition and detergency to the lubri-cant.  These additives may also impart rust preventive properties to the oil or fuel, and as V.I. improvers they can be formed to have particularly good low temperature viscosity effects in lubricating oil.

Abstract: Abstract of the Disclosure One or more quartz tubes are utilized in an appliance for the concentration of for example sulphuric acid.  Each quartz tube is heated from the outside, and the acid which is to be concentrated is fed in at the upper part of each tube.  Concentrated acid is drained off from the lower part of each tube into a vessel and the vapours driven off from the acid during the concentrating process rise inside each tube, and are led off from the upper part of each tube.  Inside each tube the acid first passes through a rectifica-tion zone located in the upper part of the tube, and then passes through a liquid film zone and a reservoir zone in that order.  In the rectification zone the rising vapours cause, among other things, the inner surface of the quartz tube to be kept well moistened.  In the liquid film zone is located one or more rotary devices which turbulate the rising vapours, whereupon they can act jointly with the acid dripping from the rectification zone so that the said drops of acid disintegrate and are thrown against the inner surface of the tube in the liquid film zone.  The rate of flow and turbulence of the rising vapours and the supply of acid are so selected that the drops disintegrate, and together with the acid running down the in-ner surface of the liquid film zone from the rectification zone, form an essentially unbroken liquid film over the latter mentioned inner surface.  In the reservoir zone the acid running down from the liquid film zone is collected.  The collected acid is made to circulate while being boiled by means of the circulatory device located in the reservoir zone, from which the surplus concentrated acid is drained off via an overflow to the said vessel.
