Abstract: An apparatus for printing variable identifying information on the tape is disclosed. In a particular application, the apparatus replaces a labeling station and is combined with a case sealing station to seal cases with adhesive sealing tape on a conventional production line. The apparatus includes a variable image printer, and preferably a thermal printer. The thermal printer preferably includes a thermal transfer print head and a thermal transfer ribbon specially engineered to print through the release agent on the face of the tape. The tape is dispensed from a tape unwind spool and is routed past the print head with the thermal transfer ribbon positioned between the print head and the face of the tape, and the face of the tape opposite the print head. The thermal transfer ribbon is co-engineered with the tape to be compatible with the physical characteristics and chemical composition of the tape.

Abstract: A label tamp is provided for delivering and applying a linerless adhesive label to the outside surface of a container transported on a conveyor to the labeling station of a production line. The label tamp includes a tamp cylinder defining an axis of extension that is generally normal to the outside surface of the container, a tamp arm secured to the tamp cylinder such that the tamp arm is alternately extensible and retractable, a tamp arm base plate rigidly fixed to the tamp arm and a tamp head assembly. Preferably, the tamp head assembly is secured to a lift plate has a pair of parallel recesses for receiving a pair of linear actuators therein so that the tamp head assembly is linearly movable relative to the tamp arm base plate.

Abstract: A method for countering the adverse effect of contaminating metals on a crystalline aluminosilicate catalyst comprising contacting the catalyst with a reducing gas under suitable conditions. In a preferred embodiment, the catalyst contains antimony.

Abstract: Process and apparatus for continuous production of disulfides by reacting at least one mercaptan and oxygen in the presence of a suitable catalyst selected from the group consisting of an alkaline earth metal oxide alone or in combination with an alkali metal oxide, on a refractory support, or a basic form of macroreticular polystyrene-divinyl benzene copolymer.

Abstract: A coating composition for providing (especially temporary protective) coatings on surfaces (especially the hydrophobic paintwork of newly finished motor vehicles) which comprises particulate copolymer dispersed in water containing less than 10 wt % of volatile organic solvent. The particulate copolymer comprises 7 to 14 wt % acrylic or methacrylic acid, 0.1 to 10 wt % hydrophilic monomer (e.g. methacrylamide) and other monomers. The coatings are transparent, abrasion resistant, tenacious yet easily removable to produce environmentally acceptable effluent.

Abstract: Activated olefinically unsaturated organic compounds such as esters, acids, ketones, nitriles, and the like, are reacted with hydrogen sulfide in the presence of at least one of magnesium oxide and anion exchange resins catalysts to produce saturated sulfur-containing compounds. In a specific embodiment, unsaturated carboxylates are converted in high yields to mercaptoalkanoates.

Abstract: Oxa-organic sulfur compounds, methods of preparing such compounds and methods of using the compounds as polymer chain length terminating agents are provided.

Abstract: Organothioalkanols are prepared by reacting a mercaptan with an aldehyde or ketone. Reaction impurities, such as water, are removed to enhance product stability.

Abstract: A process for preventing the substantial decomposition of an alkyl sulfide compound at high temperatures comprising combining a non-reactive basic compound with the alkyl sulfide compound prior to subjecting the resultant mixture to the high temperatures.

Abstract: Interchange reactions between organosulfides and mercaptans are promoted by the use of catalysts containing Group VIB oxides. The preferred catalysts are supported phospho Group VIB oxide acids, such as phosphotungstic acid and phosphomolybdic acid. The preferred supports are moderately acidic supports that contain aluminum, such as zinc aluminate and aluminum phosphate.

Abstract: An improved process is provided for reacting starting materials in the presence of an acid catalyst in a reaction zone to produce an acid sensitive product. The starting materials are circulated in the reaction zone through a fixed bed of solid acid-type ion exchange resin to thereby catalyze the reaction, and the resulting reaction product is withdrawn from the reaction zone. Starting materials comprised a mercaptan and an aldehyde or ketone are reacted in accordance with the process to produce high yields of aliphatic hydroxyalkyl or hydroxyaryl sulfide.

Abstract: A method for the conversion of mercaptoalkanols to dithiodiglycols having good color properties and low residual odor is provided. Mercaptalkanols are reacted in the presence of small amounts of anhydrous ammonia and an oxygen-containing gas in the absence of any metal-containing catalysts to produce the desired dithiodiglycol products.

Abstract: Improved rate of dissolution in liquid hydrocarbon fuels, of specified tert-butylstyrene copolymers capable of imparting anti-misting characteristics to the fuel, is obtained when the copolymer, following its production by aqueous emulsion polymerization of the monomers, is isolated from the resulting latex by a process of flocculation, separation, washing and drying at moderate temperatures. The copolymer thus isolated is advantageously incorporated in the liquid fuel in the form of a slurry with a hydroxylic liquid and an amine.
