Abstract: A process for upgrading plastic material containing inorganic filler or reinforcement material for use as feedstock in a partial oxidation gas generator for the production of raw synthesis gas, fuel gas or reducing gas. The plastic material is granulated and partially liquefied by heating in a closed autoclave at a temperature in the range of about 400.degree. F. to 495.degree. F. and a pressure in the range of about 150 psig to 750 psig while the plastic material is in contact with a pumpable hydrocarbonaceous liquid solvent. A pumpable slurry is thereby produced comprising solubilized plastic, unsolubilized plastic, hydrocarbonaceous liquid solvent, separated inorganic material and unseparated inorganic material. After removing the separated inorganic material, the remainder of the slurry is then reacted by partial oxidation to produce said raw synthesis gas, fuel gas or reducing gas.

Abstract: This invention relates to the production of hydrogen-rich gas by the partial oxidation of a saturated gaseous hydrocarbonaceous fuel or a mixture of saturated gaseous hydrocarbonaceous fuel and a liquid hydrocabonaceous fuel in a gas generator. In the process, a saturated gaseous hydrocarbonaceous fuel from a subsequent fuel gas saturator is preheated by indirect heat exchange with a portion of shifted process gas stream from a catalytic water-gas direct shift conversion zone and reacted in said partial oxidation gas generator. The process gas stream from the noncatalytic partial oxidation gas generator is quench cooled and scrubbed with water and preheated by indirect heat exchange with a second portion of the process gas stream from the shift conversion zone prior to catalytically reacting the CO and H.sub.2 O in the process gas stream in the shift conversion zone to increase its H.sub.2 content.
Abstract: A discharge system is used with a tire liquefaction process using a reactor. The system includes a receiver receiving unreacted components, including oil coated metal from the reactor. The unreacted components are moved through a pyrolysis reactor where they are heated to a temperature sufficient to convert the unreacted hydrocarbon components to a liquid and to a gas by way of pyrolysis. The liquid and the majority of gas are drawn off from the pyrolysis reactor. Discharge apparatus connected to the pyrolysis reactor converts the remaining gas to a condensate and discharges the metal. The condensate is also removed for further use.

Abstract: A printing ribbon spool and method of replenishing ink to printing ribbons are disclosed. The spool has a central ink reservoir, and a pad of cellular material, preferably a spun-bonded fibrous material, which receives ink from the reservoir and has an exposed periphery beneath the lower edge of the ribbon as it pays on and off the spool. Ink is conveyed from the reservoir through the pad of cellular material to the exposed area of the pad, and a lower area of the ribbon contacts the exposed area of the pad to pick up ink therefrom and to transmit ink upwardly of the ribbon by capillary action to the type slug impact area of the ribbon. Preferably, both the supply ribbon spool and a take-up ribbon spool have a similar construction, so ink is supplied to the ribbon both as it is unwound from the supply spool and as it is wound up on the take-up spool. The ink reservoir can be closed for storage and shipping and opened when the spool is prepared for use.
Abstract: A pulley configuration which increases the contact area between the pulley tooth tips and the land area of the belt teeth. The increased contact area reduces land area wear between belt teeth. The pulley tooth tip has a longitudinal cross-sectional contour partially composed of two substantially circular arcs connected by a line segment which is substantially straight or slightly curved. The length of the line segment is from 2 percent to 100 percent of the width of the belt tooth on which the pulley is used, and preferably less than about 7 percent of the width of the belt tooth. The pulley groove depth may be less than the height of the belt tooth and the groove has a longitudinal cross-sectional contour partially composed of two substantially circular arcs connected by a line segment which is substantially straight or slightly curved. The pulley in combination with a toothed belt forms a positive power transmission system.
