Abstract: SYSTEM FOR HANDLING HIGH SULFUR MATERIALS                  ABSTRACT OF THE DISCLOSURE         Sulfur oxides have a strong affinity for free lime and readily form gypsum anhydrite.  By utilizing 2200° F. or higher on-gas containing reduced quantities of sulfur to the preheat zone of a material treating apparatus, large quantities of sulfur can be evolved in the rotary kiln.  Utilizing lower sulfur content on-gas to preheat will substantially improve the ability of the system to lower both sulfur and alkali levels in the clinker. Substantially free lime in the form of fines is introduced into the kiln off-gas stream to form gypsum anhydrite which is removed and has the potential to be utilized as a commercial by-product.  Essentially all of the remaining gaseous sulfur that has not been absorbed by the lime bearing dust is absorbed by the free lime in the pellets in the preheat zone of a material treating apparatus.

Abstract: U-CLIP FOR BOLTLESS BLADE RETAINER                    Abstract Both the disk and the blade retainer have a radially inward extending flange which axially abuts the other. A U-clip ring with its open side disposed radially outward is placed over the two flanges to hold them axially together and means is provided to maintain the U-clip ring in its holding position. In a preferred embodiment, the ring is constructed with its side farthest from the disk having a substantially greater radial height than that of the side closest the disk, and the circumferential length of the U-clip is so sized that there is a relatively small gap between its ends when it is in the installed position. With these features, the ring will remain in its assembled position without any other holding means. Removal can be effected by first radially moving one end of the ring inwardly with respect to the other and then axially moving it until it clears the other end.

Title: Inert carrier gas heat treating control process

Granted: 1982-06-08
Abstract: INERT CARRIER GAS HEAT TREATING CONTROL PROCESS         ABSTRACT OF THE DISCLOSURE   Ferrous articles are heat treated by introducing a gaseous carbon source and an inert carrier gas into a heat treating furnace containing the ferrous articles.  The heat treating process is controlled by determining the amount of carbon monoxide resulting from reactions in the furnace and controlling the amount of inert carrier gas in the furnace in response to the amount of carbon monoxide in the furnace atmosphere to control the carbon potential to a desired level by minimizing the effect of equilibrium reactions. Best results are achieved when the amount of carbon monoxide is less than about 3%, preferably, less than about 1%, by volume.  Controlling the carbon monoxide level will minimize the effect of harmful decarburizing agents (oxygen, carbon dioxide and water vapor).  Under the reaction conditions existing within the furnace operated in accordance with the present invention, hydrocarbon dissociation reaction and primary carburizing reaction are nonequilibrium reactions and control the process results.  Oxidation reactions, secondary carburizing reaction and hydrogen decarburizing reaction are equilibrium reactions but are minimized when the inert carrier gas level within the furnace is used to control the carbon monoxide level, especially less than about 3%, preferably less than about 1.0% by volume.  Carburizing is a preferred heat treating process and can be carried out using a hydrocarbon source such as methane and an inert carrier gas such as nitrogen.

Abstract: ABSTRACT    Several new treatment processes and compositions for practicing these processes are provided which substantially alter the fluid flow and surface characteristics of porous permeable particulate formations, especially subterranean formations intersected by an oil well.  The compositions of this invention also provide methods of increasing viscosity or gelling aqueous fluids, especially acids, which can be used to treat such earthen formations.  Treatment of the earthen formations with the compositions of this invention can substantially modify the permeability and surface characteristics of the formation to prevent or reduce the flow of aqueous fluids, especially water and formation brines through that portion of the formation, thereby re-ducing the water-oil ratio of fluid flowing through or produced from that formation and in some cases enhancing the hydrocarbon production.  The treatment of this invention uses branched organic polymers of a wide molecule  weight range. The branches are preferably hydrophilic and the polymer contains bonding groups (e.g. ionic bonding groups) which serve to attract or repel a substrate, a particular forma-tion, suspended solids, other polymers or segments, carrier fluid or a fluid to be treated.
