Abstract: Abstract The invention relates to a process for decarboxylative oxidation of a benzene monocarboxylic acid or a salt, ester or anhydride thereof, in the liquid phase and at an elevated temperature, with the aid of a gas containing molecular oxygen.     According to the invention the tarry product formed is subjected to a hydrogenating treatment, either in the absense of a catalyst at a temperature of, preferably, 400-1200°C, or in the presence of a catalyst, for instance a hydro-cracking catalyst or a catalyst promoting the formation of cyclohexanone and/or cyclohexanol possibly substituted in the ring.     The invention provides the possibility of converting a by-product, so far unusable, into useful products, particularly a phenol or a cyclohexanone and/or cyclohexanol. A particularly advantageous application of the process invented lies in the preparation of cyclohexanone and/or cyclohexanol on the basis of benzoic acid.

Abstract: ABSTRACT OF THE DISCLOSURE :           Improvements in continuous ring furnaces for baking and rebaking carbon articles which consist in providing Acheson-type furnaces with a movable connecting member having means adapted to produce a gas flow, said member connecting the first chamber being cooled with the corresponding inlet of the smoke channel.  In operation, said means, which produce a gas flow, draw a portion of the smoke flowing in the common smoke channel and force said portion to be recycled into said first chamber being cooled, increasing the pressure therein.  These improvements provide a decrease in the quantity of gas passing through the filter, an increase in the thermal efficiency of the furnace, and a decrease in the fuel consumption.

Abstract: ABSTRACT OF THE DISCLOSURE         A composite container is disclosed that includes a helically-wound label layer which contains a line of perforations that extends circumferentially adjacent and spaced from a metal end closure member, thereby to define a line of tear along which the label layer may be torn from the container.  By the provision of the perforated tear line, the requirement of a circumferential collar cut in the container is avoided, thereby permitting the use of a thinner fibrous body wall layer.  Preferably the line of perforations is discontinuous to define an imperforate portion of the label layer which is bonded in straddling relation across the helical butt joint contained in the fibrous body wall layer.

Abstract: Abstract of the Disclosure A process for continuously forming a fibrous element In an elongate closed foraminous former during movement of the former through fluid extraction means.  The process forming a fibrous dispersion and injecting the dispersion into the former.  A pressure gradient Is generated across an extraction zone within the fluid extraction means.          The fibrous dispersion is injected into the former at an injection velocity relative to the speed of the former (efflux ratio) to cause some of the fibres to build up as a fibrous mat on the inner surface of the former.  The remainder pack together to form a core so as to produce a continuous fibrous element having a fibrous core which is enclosed by a crust of greater density.  The element is particularly useful as a cigarette filter of high structural integrity that does not require further surface treatment such as wrapping.

Abstract: ABSTRACT OF THE DISCLOSURE:         An elastic detergent bar which may also be used by children as a toy or plaything while taking a bath, includes a mixture of anionic and amphoteric synthetic organic detergents, gelatin and water. The bars are substantially form-retaining and although they wear away during use, substantially retain their initial forms and elasticities for major pro-portions of their useful lives. They are easily manufactured and during the manufacturing process are moldable to finely figured and detailed shapes. Because of their elasticity they are resistant to breakge during shipping and use and because of their contents of both synthetic anionic and amphoteric organic detergents they exhibit less surface tackiness than other elastic detergent bars in which similar proportions of gelatin and water are present. In an improved process for the manufacture of such bars having a lesser tendency to shrink upon prolonged exposure to the atmos-phere, during the blending of the various bar components heating is employed and is continued for a long enough time to evaporate a substantial proportion of water from the mixture, after which the composition may be poured into molds and solidified.

Abstract: SIGNALING STORAGE IN DIGITAL CHANNEL BANKS          Abstract of the Disclosure In a digital channel bank, the binary signaling states (on-hook, off-hook) are updated periodically for each channel.  Some number (n ? 2) of the most recent of these samples are stored at the receive end of the digital system for each message channel.  Under normal working conditions the output (to the switching machine) is directly influenced by the incoming real-time samples.  However, when a carrier disturbance (i.e., out-of-frame condition) is detected, the updating process is stopped and the output is controlled by the older stored bits.  That is, instead of sending the real-time signaling information of each channel to the switch, the signaling bits that were received and stored during a previous frame (e.g., 12 or more frames earlier) are now coupled to the switch.  This assures a high probability that the proper signaling state is presented to the switch during short carrier disturbances.

Abstract: MULTI-REACTOR HYDRODESULFURIZATION PROCESS     Abstract of the Disclosure An asphaltene-containing oil hydrodesulfurization process employing upstream and downstream reactors in series with an inter-stage flashing step.  The catalyst in the downstream reactor com-prises supported Group VI and Group VIII metals together with a promoting amount of Group IV-B metal.  The particles of the catalyst in the downstream reactor are in the form of extrudates whose sur-face is provided with a plurality of alternating longitudinal grooves and protrusions.  The catalyst in the upstream reactor comprises Group VI and Group VIII metals without promotion with Group IV-B metal and is in the form of particles whose surface may or may not have a similar grooved form.  An advantageous mass velocity-related activity effect has been found when the downstream reactor has a diameter which is smaller than the diameter of the upstream reactor.  The reduced diameter provides a concomitant advantage related to hydrogen pressure since it is shown that the reduced diameter permits the downstream reactor to withstand en-hanced pressures and it is also shown that the promoted catalyst is particularly susceptible to regeneration via increases in hydrogen pressure.
