Abstract: Abstract of the Disclosure A process and apparatus for recovering hydrocarbons from an air-hydrocarbon vapor mixture such as the mixture of air and vaporized light hydrocarbon compounds expelled as a result of loading gasoline or the like into storage tanks, tank cars and tank trucks.  The air-hydrocarbon vapor mixture is caused to flow through a bed of solid adsorbent whereby the hydrocarbons are removed from the mixture and a residue gas stream comprised of substantially hydrocarbon-free air is produced.  The substantially hydrocarbon-free air is vented to the atmosphere and a second bed of solid adsorbent having hydrocarbons adsorbed thereon is subjected to conditions which cause desorption of the hydrocarbons and thereby regeneration of the bed.  The flow pattern of the inlet air-hydrocarbon vapor mixture and the bed of solid adsorbent being regenerated are periodically changed so that when the bed through which the inlet air-hydrocarbon vapor mixture is flowing becomes loaded with adsorbed hydrocarbons, the inlet air-hydrocarbon vapor mixture is caused to flow through the bed which has just been regenerated.  The regeneration of the beds is accomplished by evacuating the beds with vacuum pumping and the air-hydrocarbon vapor mixture produced in the regeneration of the beds is contacted with a liquid absorbent whereby a major portion of the hydrocarbons are absorbed therefrom and recovered.  The beds of solid adsorbent are cooled, at least while the air-hydrocarbon vapor mixture is flowing therethrough and hydrocarbons are being adsorbed on the bed, to prevent the beds from overheating due to side exothermic reactions of hydrocarbons and/or impurities contained in the air-hydrocarbon vapor mixture with air and/or the solid adsorbent.          Apparatus for carrying out the process of the present invention is also provided.

Abstract: ABSTRACT    Solid sulfur pellets are made by dropping sulfur parti-cles in two distinct curtains of particles within a drum having a tumbling bed of such particles.  The larger curtain of particles is sprayed with molten sulfur and the smaller is sprayed with water above the bed.  This indirect appli-cation of water keeps the temperature of the bed as well as the other curtain of particles being sprayed with sulfur within predetermined temperature ranges which produce high quality sulfur pellets.  Dust emissions are prevented by classifying as to size a third falling curtain of recycled particles and spraying molten sulfur on the side containing dust particles.  Seed nuclei are produced by intermittantly raising the temperature of the tumbling particle bed about 40°F for short periods of time.

Abstract: MICROPROCESSOR ARCHITECTURE HAVING                    INTERNAL ACCESS MEANS            Abstract of the Disclosure A processor architecture is disclosed which permits the registers and control latches of the processor to be easily accessed without using instructions to achieve such access.  The architecture provides for an internal access (IA) function which is enabled by applying an IA Request signal to an IA terminal of the processor.  During the IA function, normal program execution in the processor is suspended and the registers and control latches may be accessed as if they were storage locations in a random-access memory.  After the IA function is enabled, the address of a register or control latch selected for access is applied to the Address/Data port of the processor, and an IA Control Code specifying the storbing of the Address/Data port is applied to the Status terminals of the processor.  After strobing of the address, a second IA Control Code specifying either reading or writing of the selected register or control latch is applied to the Status terminals. If the second Control Code speciifes reading, the contents of the selected register or control latch is provided at the Address/Data port.  If the second Control Code specifies writing, data received at the Address/Data port is stored in the selected register.
