Abstract: A simple, inexpensive gun-type dispenser is disclosed whereby purchased cartridges of heat softenable adhesive or sealant compound can be heated and dispensed during non-commercial projects such as crack sealing or gluing of components by a home handyman. The dispenser comprises a barrel having a breech with an axially aligned opening therein for the loading of cartridges of the compound to be dispensed, a breech access for uncovering the breech opening and for closure thereof after the insertion of a cartridge, electrical heating elements for heating the outer end of the barrel, and a mechanical feeder for urging the compound into the heated end of the barrel.
Abstract: Chemical waste by products are used in place of conventional heating fuels both for induration and chloridization of impure iron oxide. Pelletized iron oxide is hardened and purified simultaneously by exposure to the heat and combustion products generated from burning chlorinated organic by-products. Hydrogen chloride produced during this combustion reacts with trace metal impurities in the iron oxide to effectively remove substantially all such impurities as volatile metal chlorides. Conventional fuel and binder requirements are substantially reduced or completely eliminated through use of such by-products, while remedying the problem of their disposal.
Abstract: A method or process for transferring finely divided solids from a first location under the influence of atmospheric pressure to a second location under the influence of pressures of the order of 500 to 10,000 psi.
Abstract: A process for producing and upgrading carbonaceous tars including adding the carbonaceous material into a first reaction zone of a reactor having at least two reaction zones; adding hot hydrogen to the stream of carbonaceous material to effect a reaction with same to produce reaction products; quenching the mixture while insuring that the total residence time varies from about 2 milliseconds to about 2 seconds; removing at least a portion of the reaction products from the quenched mixture; introducing the residual carbonaceous material into a subsequent reaction zone and repeating the steps for the subsequent reaction zone; and introducing carbonaceous tars produced directly into a fluid coking zone to obtain gas, upgraded coal tars, and hot coke.
Abstract: An improved process for treating a hydrocarbon stream exiting the hydrocarbon-acid separator of an anionic surfactant promoted, sulfuric acid catalyzed, light olefinisoparaffin alkylation unit wherein the stream contains the alkylate, excess isoparaffins, traces of the acid alkylation catalyst, and an anionic surface-active alkylation promoter. The improvement comprises mixing, prior to introducing into a hydrocarbon-caustic separator, the hydrocarbon stream with a water-caustic solution having at least 15% by wt. concentration of caustic such that the salt of the promoter appears as a flocculent precipitate at the hydrocarbon-water-caustic solution interface in the hydrocarbon-caustic separator.
Abstract: A mixture of carbon dioxide and a carbonaceous material, such as coal, is rapidly heated in a reactor, giving a gaseous effluent comprising carbon monoxide. If hydrogen is added with the feed stream, a CO--H.sub.2 mixture is produced.
Abstract: A conductive interface forms between the oil and water layers in a coalescer apparatus for treating slop oil. The presence of this interface is detected by (a) a capacitance probe and (b) extensions on the coalescer plates. Changes in the feed and discharge rates can then be made, assuring continuous operation.
Abstract: A subterranean formation is penetrated by a borehole. The formation is fractured and propped with a slurry capable of maintaining a thermit reaction. The slurry is ignited. Upon cooling, a solid metal conductor fin network from the bore into the formation is formed in the fracture system. Energy is transferred between a locus in the borehole and the formation by the network.
Abstract: An emulsion of crude oil and water that is recovered from an underground reservoir is broken by the addition of a naturally occurring brine to effect separation and recovery of the oil phase of the emulsion. Advantageously, brine taken from the same geologic formation as the crude oil can be used as the emulsion breaker.

Abstract: A process and apparatus for recovering copper values from acidic solutions containing dissolved copper is disclosed. The process and apparatus comprises reacting in an intake line and feed pump powdered iron in the size range of up to -40 mesh with the solution to displace the copper therefrom as metallic copper, and separating the copper from the solution by settling the metallic copper in the bottom of a vessel known as a polishing tower. Preferably, the solution is clarified by passing it upwardly through a bed of scrap iron, after which the solution is centrifuged to remove particles therefrom.
Abstract: A composition comprising a hydrocarbon wax having about 10-40% by weight of oil, an ethylene/propylene/non-conjugated polyene terpolymer having a combined ethylene content of about 30-85% by weight and an iodine number of about 5-15, and said terpolymer constitutes from about 6% by weight to about 30% by weight of said composition.
Abstract: Crushed carbonaceous fuel is rapidly mixed with hot hydrogen, at 500.degree. to 1,500.degree. C. and 0 to 250 psig., in a reactor, and then, after a short reaction time, rapidly quenched. The total heat-up, reaction, and quench time is less than 2 seconds. This short residence time and rapid heat-up results in a high yield of carbonaceous tars. The carbonaceous tars are subsequently and directly introduced into a fluid coker to obtain gas, upgraded carbonaceous tars, and hot coke.
Abstract: A process for treating carbonaceous material with hydrogen at low pressure including adding the carbonaceous material into a first reaction zone of a reactor having at least two reaction zones; adding hot hydrogen to the stream of carbonaceous material to effect a reaction with same to produce reaction products; quenching the mixture while insuring that the total residence time varies from about 2 milliseconds to about 2 seconds; removing at least a portion of the reaction products from the quenched mixture; and introducing the residual carbonaceous material into a subsequent reaction zone and repeating the steps for the subsequent reaction zone.
Abstract: A dry predispersed coated pigment, immediately suitable for mixing in an ink system without milling, is prepared byA. mixing at least 90 parts of a pigment (e.g. carbon black) and not more than about 10 parts of a hydrocarbon natural fossil resin, solvent-extracted from coal,B. fusing the mixture,C. milling the mixture to obtain the approximate particle size distribution of the original pigment, andD. densifying or beading the mixture.The product having this composition and prepared by this process is a dry pigment suitable for simple mixing with an ink system to give a ready-to-use printing ink.
Abstract: Intumescent amine-aldehyde copolymer compositions having improved UV stability are obtained by incorporating about 0.5-75% by weight of a polyol polyacrylate or polyol polymethacrylate into an intumescent composition comprising a low molecular weight, water-insoluble amine-aldehyde copolymer consisting essentially of repeating units which correspond to the formula: wherein Q is the residue of an alkanal containing 1-5 carbon atoms and R is hydrogen, alkyl, haloalkyl, alkoxy, haloalkoxy, halo, nitro, acetamido, or sulfonamido. The preferred compositions are those in which the amine-aldehyde copolymer is a sulfanilamide-formaldehyde copolymer and the polyol ester is a liquid ester.
