Abstract: PROCESS FOR HALOGEN PRODUCTION            Abstract of the Disclosure Chlorine or bromine are produced from the respective hydrogen halide in a reaction system, wherein a stoichiometric excess of active nitrogen is maintained within the reaction system over the amount of hydrogen halide in the system. Preferably the reaction system is a single tower wherein sulfuric acid is introduced to the top of the tower where it absorbs the active nitrogen while conditions are so set that at the bottom of the tower the gases, introduced there, strip the active nitrogen away from the acid.  It is a further characteristic of the process that the nitrogen compounds stripped at the bottom, are mainly stripped as a mixture of nitrogen monoxide and nitrogen dioxide. A major portion of the nitrogen monoxide stripped, is oxidized with the oxygen, present in the gases fed in the bottom, to form nitrogen dioxide.  If hydrogen halide is fed in the bottom, it will also strip nitrogen compounds, but mostly in the form of nitrosyl-halide.  Oxidation of nitrosyl-halide with oxygen, either direct or indirect (via decomposition of the nitrosyl-halide into nitrogen monoxide and chlorine), does not play a significant role in the present process.  In the reaction section of the process, where practically all the halogen is formed, the characteristic phenomena is, that the chlorine or bromine made there in gas phase, is all formed by reaction of nitrogen dioxide and hydrogen halide or nitrosyl-halide, while the sulfuric acid absorbs the active nitrogen compounds mainly in the form of nitrosylsulfuric acid, thus helping the reaction to proceed.  A small amount of hydrogen halide is preferably left unconverted.

Title: Process for producing shaped synthetic resin articles varying in shape of longitudinal section
Inventor: KIMURA TAKASHI
IPC: B29C43/24
Filed: 1975-06-11
Granted: 1979-12-04
Abstract: ABSTRACT OF THE DISCLOSURE          A shaped synthetic resin article varying in cross-sectional area and shape of longitudinal section along at least a part of the length is continuously produced by introducing a molten synthetic resin composition extruded from an extruder die between at least one pair of rolls rotating in the direction of extrusion so that the rolls of each pair contact each other on their periphery, the peripheral surfaces of the rolls being engraved so as to form a cavity corresponding to the shape of said shaped article when the rolls of each pair contact each other while being rotated, in which cavity the molten resin composition is remolded into an article having the desired shape and at the same time the surplus resin composition overflowing from said cavity is cut off by the edges of said rolls contacting each other, and then cooling the molded article to solidify the same.  According to the above process, the diameter of the minimum cross-section of the article can be made much smaller than the outer diameter of the die or nozzle.

Abstract: Abstract of the Disclosure A semiconductor structure from which various types of active semiconductor devices can be formed is made of a semiconductor island on a transparent substrate, having thereon an electrically insulating layer of a protective material, such as silicon dioxide, which extends onto and covers the sides of the semiconductor island.  The protec-tive layer can either cover only the sides of the semi-conductor island or extend over the top edge of the island. The structure wherein the protective layer covers only the sides of the island is made by etching through a photoresist mask made of a negatively reacting photoresist which is formed by exposure to irradiation from beneath the uncovered surface of the substrate, whereby the thickness of the silicon island and the flux density of the irradiation are selected so that for a particular duration, the irradiation is completely attenuated by the semiconductor island.  This causes photoresist not on the top of the island to be exposed.  Regions of the protective material above the surface of the island which are not protected by the photo-resist mask are etched away.

Abstract: ABSTRACT OF THE DISCLOSURE         Conventionally, it is usual to try and clean snow and the like from the lower portion of roofs and associated eaves-troughs, with a brush or similar instrument to prevent ice bulid up in the spring.  This is difficult particularly if standing on a ladder or the like which is usually necessary in order to reach the roof and eavestrough.  The present device includes one or more raking portions anyone of which may be attached to a relatively long telescopic handle, for cleaning snow from the lower portion of the roof.  The raking portion may then be removed and a fur-ther portion attached which extends substantially at right angles to the handle and holds a garden hose nozzle.  By passing a garden hose through the hollow handle and connecting the hose to a source of water under pressure, the eavestrough can be flushed out with-out the necessity of standing on a ladder.  The device can of course be used to clean eavestroughs of snow and ice or of leaves, mud and the like.

Abstract: ABSTRACT OF THE DISCLOSURE     Total washing efficiency in countercurrent washing of cellulose pulp from alkali digestion is increased by lower-ing the pH value in liquid cycles of the washing system to reduce environmental pollution by lowering the pH value of the waste liquor.  Foaming of waste liquor is also reduced considerably.  The acid wash increases the whiteness of the fibres when lowering the pH value by application of an oxid-izing acid which is of significance in producing unbleached grades.

Abstract: ELECTRICALLY PUMPED, SOLID-STATE DISTRIBUTED FEEDBACK   LASER WITH PARTICULAR GRATING SPACING               ABSTRACT OF THE INVENTION           A distributed feed back  (DFB), electrically pumped diode laser in which the spacing of the periodic structure within the diode is selected to optimize the interaction between the periodic structure and the electromagnetic waves in the diode laser.  The degree to which the waves interact with the periodic structure is described mathematically by a coupling constant K, with larger values of K corresponding to lower gains required to produce laser operation.  It is shown that in DFB diode lasers higher order transverse modes have a higher coupling constant K with the periodic structure than does the lowest order transverse mode and thus the higher order transverse modes will lase more easily than the lowest order transverse mode.

Abstract: A method for analyzing the dimensional characteristics of micron or submicron-sized bodies such as particles, cells, organisms, and the like, by using particle detecting means to produce an electrical primary pulse as a function of a dimensional index of the bodies, ant thereafter feeding the primary pulse to secondary pulse-producing means, which means are triggered at different time intervals during the duration of the primary pulse or during the duration of a number of primary pulses generated by the same type of bodies such that a plurality of secondary pulses are procuded.  These secondary pulses, each having an amplitude reflecting the relative amplitude of the primary pulse at the time of triggering are produced for subsequent use to reflect the shape of the primary pulse such that a characterization of the bodies being analyzed can thereby be obtained.  The secondary pulses not only can be used either to profile the primary pulse or to permit the area integration thereof, but the technique of a multi-point triggering of secondary pulses is useful also in biological particle total count and size distribution assay methods in that the "signature" of the particle population being studied is meaningfully emphasized even if only a single-pass sample run is employed.
