Abstract: A sealed glass tube has a gaseous filling which when subjected to high voltage produces a radiation of energy through the tube. An elongated electrical conductor is mounted lengthwise in the tube and subjects the gaseous filling to high voltage to provide electrical communication with the exterior of the tube and form ozone with an encircling perforated metal grid. The tube is supported within the grid by spacers secured to internally facing valleys of the fluted grid. The flutes of the grid extend fully from one end to the other to provide maximum output. In a preferred form of the invention, the rearward end of the conductor is slidably supported to for expansion and contraction. Also, the conductor includes an auxiliary portion extending through and having sealed relation with one end of the tube, the auxiliary portion having a wound connection to the conductor.

Abstract: Para selectivity in the conversion of a monosubstituted benzene containing a meta-directing group to disubstituted benzenes can be substantially enhanced by carrying out the reaction in the gas phase with an inorganic or organic substitution agent in the presence of a catalyst composition comprising a crystalline molecular sieve material. In particular, nitrobenzene can be converted using nitrogen dioxide in the gas phase to a product containing an augmented proportion of para-dinitrobenzene using a wide range of catalyst compositions comprising both synthetic and naturally occurring crystalline molecular sieve materials such as ferrierites, X-type zeolites, Y-type zeolites, silicalite, framework-modified silicalites, ZSM aluminosilicates, AMS-1B borosilicates, and AlPO.sub.4 types.

Abstract: The invention relates to an apparatus for conducting a molecular gas or gas mixture containing at least one molecular component, in a closed circuit, in particular for the purpose of generating processes in the gas or gas mixture involving its partial ionization and the stimulation of molecules to vibrate in the corresponding gas component. The apparatus comprises two similarly designed flow channels preferably having a rectangular cross-section. The broadsides of the channels are arranged beside each other or constructionally integrated and are connected with each other at their adjacent ends by two apparatus for circulating gas, in such a way that the gas can flow through them in opposite directions. Electrodes are set in partial areas of each channel, electrically insulated from the channel walls, the electrode closer to the other channel in each case being electrically connected, or constructionally identical, to the corresponding electrode of this other channel.

Abstract: Disclosed is an apparatus for cleaning sulphur and nitrogen containing flue gases by adding gaseous reagents and by a reaction in a reaction chamber which the reactants pass through in the axial direction and are exposed to at least one electorn beam. The apparatus includes at least one reaction chamber and at least one electron beam source from which the electron beam is admitted into the reaction chamber through at least one pressure step zone. The electron beam source is structurally combined with the reaction chamber in such a manner that the axis of the pressure step stage runs parallel to the axis of the reaction chamber and that the electron beam can be rotationally deflected about this axis to traverse each surface element of a flow cross section of the reaction chamber running perpendicular to the axis at at least one position in the flow path.

Abstract: A process for inducing photochemical reactions using laser radiation employs a dielectric waveguide cell formed by a capillary passage communicating at its ends with a gas inlet chamber and a gas outlet chamber, each chamber being configured to encompass a cone of laser radiation focussed onto, or diverging from, the respective end of the capillary passage. The passage is configured to propagate the laser radiation therealong in one or more selected waveguide modes, thus defining an extended region of high fluence.

Abstract: An improvement upon processes for the bleaching of wood pulp which comprise preparing an aqueous alkaline bleaching medium containing hydrogen peroxide and contacting the pulp with said medium under agitation. The improvement particularly comprises agitating a suspension of the pulp in an aqueous medium containing the hydrogen peroxide and between about 15 and 65 percent by mol of one or more of a limited class of alkenylsuccinic anhydride compounds which are found to promote the bleaching of the wood pulp by the hydrogen peroxide. The improved process of the invention is further found to be necessarily restricted to operation under limited conditions of bleaching mixture temperature and pH.The invention is usefully applied in the preparation of a wide variety of paper and paperboard products. The invention has particular benefit in accomplishing a high degree of bleaching performance at relatively low bleaching system temperatures.
