Abstract: ABSTRACT           The invention is concerned with a direct extrusion process for preparing a coating substrate  from a viscous coating composition. The process of the invention comprises feeding the component material or materials of a coating composition into an extruder having a barrel and an elon-gated extrusion die orifice leading away from the barrel  and advancing the material or materials forward in the extruder barrel to obtain a molten homogeneous composition, and then through the extrusion die orifice.  A substrate is directed into positive engagement with the outlet opening defined by the extrusion die and the homogeneous composition is extruded through the extrusion die orifice onto the substrate to force the substrate away from the die and to form a uniform coating on the substrate.  The coated substrate is then moved into immediate contact with a closely disposed coating roll.  The substrate is drawn to the die orifice from a direction such that the angle ? formed between a line representing the direction of approach of the substrate and a line representing the direction of extrusion is less than 90°, whereas the coated substrate is drawn away from the die orifice in a direction such that the angle ? formed between the direction of extrusion and a line representing the initial departing direction of the coated substrate immediately on formation when combined with the angle ? is less than 180°. The invention is particularly useful in the manufacture of viscous pressure-sensitive adhesive sheets and tapes.

Abstract: RECOVERY OF CHLORINE VALVES IN INTEGRATED PROCESS FOR OXYCHLORINATION AND COMBUSTION OF CHLORINATED HYDROCARBONS            Abstract of the Disclosure In an integrated process for oxychlorination and combustion of chlorinated hydrocarbons, chlorinated hydro-carbon is burned to recover chlorine values essentially as hydrogen chloride.  Hydrogen chloride is recovered from the effluent from the combustion by absorption with aqueous hydrogen chloride.  Hydrogen chloride recovered by the absorption is subsequently recovered and employed in an oxychlorination reaction.  A gas containing hydrogen chloride, water vapor and some oxygen recovered from the oxychlorination is cooled to condense aqueous hydrogen chloride which is employed in the absorption for recovering hydrogen chloride.  The remaining gas is employed in the combustion of chlorinated hydrocarbons.  The process has particular applicability to an oxychlorination reaction of the type wherein a molten salt containing the higher and lower valent chlorides of a multi-valent metal is contacted with hydrogen chloride and oxygen to recover hydrogen chloride by enriching the higher valent metal chloride content of the molten salt.

Abstract: ABSTRACT           MULTIRATE DIGITAL TRANSMISSION METHOD AND    DEVICE FOR IMPLEMENTING SAID METHOD            The method uses BCPCM techniques for coding the signal into subbands by dynamic allocation of the coding bits between the subbands, the rate of all subbands together being chosen so as to be the highest one in a set of predetermined rates. The bits obtained by coding the samples of the sub-bands  considered  at  a  given  sampling  instant (macro  sample)  are  distributed  according  to  a given format comprising a predetermined number of fields of a predetermined size. The distribution of said bits depends on the rank of each bit in the sample to which it belongs and on its contri-bution to the coding at each of the predetermined coding rates.

Abstract: ABSTRACT MULTILAYER AVALANCHE PHOTODETECTOR The avalanche region of a photodetector comprises layers (31,33,35,37) in which the bandgap is graded, with steps back from the wider gap to the narrower gap.  The preferred carriers (electrons) are rapidly accelerated in the regions of the steps, so that the probability of an electron causing an impact ionization in the narrow-gap region just past each step is high.  The non-preferred carriers (holes) undergo a comparatively uniform acceleration and are thus more likely to lose energy by optical phonon emission.  They are therefore less likely to cause impact ionizations.  The device noise is thus reduced. Also, the necessary bias voltage is reduced.
