A system and process is disclosed for retorting oil shale and extracting shale oil and other hydrocarbons therefrom, in which a cased heat delivery well is drilled generally vertically through an overburden and then through a body of oil shale to be retorted to the bottom thereof, generally horizontally under the body of oil shale to be retorted, and then back to the earth surface. Heat energy is transmitted conductively to the body of oil shale to be retorted from a closed loop heat delivery module in the well, the module comprising a fluid transmission pipe containing a heating fluid heated to at least a retorting temperature. Heat energy is also transmitted to the body of oil shale to be retorted above the fluid transmission pipe by vapor conduits that conduct retort vapors upward through the body of oil shale to be retorted; the ascending retort vapors condense and reflux, delivering their latent heat of vaporization to the body of oil shale to be retorted, and the condensed retort liquids descend. If not recycled, the retort liquids are collected in a sump at the bottom of a production well and are transmitted to the surface for processing. The vapor conduits communicate at upper ends thereof with the production well, so that vapors that do not reflux are collected in the production well and are transmitted to the surface for processing.

The invention relates to the devices and method of controling harmful exhaust gas of refuse by pyrolytic vaporization processing technique, uses pyrolytic vaporization to dispose waste device, said thermal dissociation method is that refuse enters the reactor through main pyrolytic stove to take pyrolytic reaction and generate mixture gas, said gas enters the mixture gas retort with the rubbish carbon together, steam generator provides steam to enter the mixture gas retort with the high-heat hot smoke gas together, and the combustion gas generated in the retort enters the main pyrolytic stove and heats the retort in the oven, the clean waste gas generated by burning is discharged out of the oven. The application of controlling chloridate vaporization in the invention is based on root, which means preventing the vaporization of the chloridate during the handling process to avoid the occurrence in theory, therefore, could abbreviate the complicated exhaust gas handling largely and no need to handle the secondary substance for exhaust gas handling again, which is just the superiority of the invention.

An automatic tissue processor for processing tissue samples for histological analysis. The tissue processor in one configuration includes a retort chamber, a wax storage chamber holding multiple wax containers, a reagent storage chamber holding multiple reagent containers, and a fluid transporting system including a rotary valve operated by a Maltese Cross gear, for selectively connecting the retort chamber with a particular wax or reagent container to supply wax or reagents to the retort chamber. Differential heating of the wax chamber is accommodated by multiple heating elements, with indirect heating of the rotary valve and the fluid transporting system. A computerized central control system for automatic monitoring and control of such tissue processor is advantageously arranged to execute a reagent management program, which enables the central control system to automatically manage reagent usage and replacement.
