Abstract: PYROLYSIS REACTION APPARATUS AND METHOD     Abstract of Disclosure Pyrolysis reaction apparatus and method are described in which carbonizable waste material is fed into the pyrolysis reaction chamber by an inlet conduit which passes through the wall of a heating furnace surrounding such chamber.  As a result, the material is immediately vaporized in the reaction chamber due to the high temperature at the inlet portion of the chamber where the material is introduced.  A fluid cooling jacket surrounds the inlet conduit to maintain the temperature within such conduit below the melting temperature of the material being transmitted therethrough in order to prevent clogging of the conduit.  The material is fed into the reaction chamber by the inlet conduit along an input feed direction which is laterally offset from the axis of the shaft of an impeller for conveying such material through such chamber and is preferably directed toward the tips of the impeller blades in order to prevent clogging of the impeller.  The treated material which may contain precious metal, such as the silver in photographic film, is heated within the reaction chamber in the absence of oxygen to decompose such material by chemical reaction into a hydrocarbon pyrolysis gas and a solid carbonized residue.  The carbonized residue material of reduced size and weight may be further processed such as by oxidation to remove the carbon and convert the silver or other precious metal in such residue into a metal oxide which is refined to recover the metal.

Abstract: TITLE AN AQUEOUS PHASE CONTINUOUS, COAL FUEL  SLURRY AND A METHOD OF ITS PRODUCTION                                  INVENTOR C. Edward Capes Adam J. Bennett Richard D. Coleman William L. Thayer ABSTRACT OF THE DISCLOSURE         An aqueous phase continuous, fuel slurry is claimed, and its method of production from agglomerates consisting essentially of carbon-aceous particles, agglomerating oil and residual water.  The slurry may be formed by thoroughly mixing with agglomerates an agglomerate dispers-ing and coal/oil/water system interfacial tension reducing agent with the agglomerates so that the agglomerates are broken down and an aqueous phase continuous fuel slurry is formed containing residual, oil produced flocs from the agglomerates and having an oil content of the fuel slurry no greater than 10 weight% of the solids content of the fuel slurry.  The solids content of the fuel slurry is in the range of the order of 50 weight% and of the order of 80 weight% of the total weight of the fuel slurry, and is preferably in the range of the order of 65 weight% to of the order of 70 weight%.  Examples of interfacial tension reducing agents are ethanol, methanol, glycol, butyl alcohol, isopropyl alcohol, lauryl sulfonates, alkyl sulfonates, lignosulfonates, sodium oleate, nonyl-phenolethoxylates, and soaps.  With fuel slurries according to the inven-tion, there may be very slow sedimentary consolidation of the carbona-ceous particles, but when it does occur there is no difficulty in re-mixing the constituents into a slurry because the residual aggregates or flocs cause the carbonaceous particles to pack down to a porous bed.

Abstract: ABSTRACT OF THE DISCLOSURE     A measurement head in an arc welding machine modulates the light intensity of a laser light beam with a modulating signal of 50 KHz or higher, and radiates the laser light beam onto an object to be measured while changing the direction of laser beam emission in one plane. A light receiving unit in the measurement head changes its direction of detecting a reflected beam in the same plane. Angles at which the light beams are emitted and detected are detected at the time a modulated signal component is detected from an output from the light receiving unit. The position of a bright spot produced on the surface by the radiated laser light beam is computed from the detected angles based on the principle of triangulation.

Abstract: Abstract of the Disclosure A system for verifying that the proper ingre-dient-containing transport containers have been assembled at a particular soup-blending kettle, in which a hole-coded metal key is permanently affixed to each container and provided with an array of machine-readable holes cor-responding to a number unique to each container.  At the ingredient-dispensing station, a key-reader reads out the identifying number of the container and transmits it to that kettle station to which the container is to be delivered.  The transport container is then delivered to the kettle station, where the key code is again machine read; the container number thus read out at the kettle station is compared with that previously transmitted from the ingredient-dispensing station, and if they both repre-sent the same number then the proper container has been delivered to the kettle station and its contents are dump-ed into the kettle.  To prevent dumping of ingredients of a "wrong" container, the container can be locked at the dispensing station and only unlocked at the kettle station in response to a control signal indicative of identity between the remotely read key and the key read at the kettle occurs.  In other cases an unlocked trans-port container is delivered onto an automatic dumper, which is enabled only in response to an indication by the control signal that the proper container is present.

Abstract: ABSTRACT          Combined antiblocking agent and lubricant con-centrate based on polyolefin, which contains diatomaceous earth, precipitated    silica and/or silica gel as the antiblocking agent, one or more amides of unsaturated C18-C22-fatty acids and optionally further conventional additives and which is characterized in that it contains 5 to 35% by weight of antiblocking agent and 5 to 30% by weight lubricant. The high lubricant concentration in the combination concentrate according to the invention is obtained in that the antiblocking agent and the lubricant are incorporated into the polyolefin in the form of a homogeneous, finely divided mixture. The antiblocking agent serves as a carrier for the micronized lubricant, i,e. the lubricant is adsorbed on the large surface of the antiblocking agent, so that the "flowing away" of the lubricant otherwise observed in the case of high lubricant concentrations during incorporation into the polyolefin is avoided. The concentrate according to the invention is more particularly suitable for use in the production of polyolefin films. Apart from action improvements, the advantages of the concentrate according to the invention are more particularly apparent in the economic field because compared with the prior art, only a single concen-trate is required which, due to the high lubricant concentration, need only be used in much smaller quantities.
