Abstract: A brine leakage monitoring system for a production oil well where brine is returned to a brine bearing strata in the ground through casing surrounding the production casing of said oil well, including means for continuously monitoring the pressure in the area surrounding the brine disposal casing to detect any leaks that might occur so that brine does not seep into any strata, other than the brine bearing strata.

Abstract: Glass or ceramic fibers or other fibers such as graphite properly protected by a suitable adherent ceramic or metal coating are immersed in a liquid metallo-organic solution containing a noble metal compound as a primary ingredient, then dried and fired in air or in a slightly oxidizing atmosphere so as to produce a noble metal coating on the fibers. Fibers may be in the form of individual filaments, as a multifilament tow or yarn or as a woven fabric. The fibers coated with a nobel metal are then incorporated into a metal matrix composite material by immersion in a molten bath of the desired matrix metal, placing the fibers in a suitable mold and casting the molten matrix metal around them or placing the fibers between solid sheets of matrix metal and effecting consolidation by diffusion bonding. The coating thickness on the fibers should be at least 0.30 microns and should not exceed 0.50 microns.

Abstract: A process for making a fibrous tofu food product having a unique structure, texture, and mouthfeel. Proteinaceous fibers, such as chopped and fluffed wet spun soy isolate fibers, are dispersed in soymilk to form a mixture. A selected edible acid (or acids), calcium and/or magnesium salts, are added to the mixture. The co-precipitate mixture exhibits physical and chemical binding which produces the unique structure or texture. The resulting coagulative mixture can then be formed into desired sizes and shapes.

Abstract: A hand operated digging tool comprising a ground penetrating portion, such as a shovel, has a lever arm hingedly attached to the back of the shovel adjacent to where the shovel engages its handle. The lever arm is provided with an extension at right angles to it adjacent to the hinged portion so as to space the lever arm from the shovel when both the lever arm and the shovel are positioned on the ground in digging position and which will push the lever arm back into engagement with a holder on the back of the handle as the operator completes the shoveling step removing the shovel from the ground.

Abstract: A glass sheet is provided with a coating which will automatically reflect infrared radiation if the ambient temperature is above about 45.degree. F.-60.degree. F. Such a coating is placed on the exterior surface of the glass. Additionally, the interior of the glass may be provided with a controllable infrared transmittable or reflective layer of material which is activated by means of an electric current transmitted therethrough and which will reflect infrared energy if so energized, but otherwise will transmit such infrared energy. This layer of material is preferably placed on the interior of the glass surface and activated during the nighttime period so that infrared energy is not transmitted outwardly. Alternatively, the controllable infrared transmittable or reflective layer of material may be positioned both on the exterior and interior of the glass surface.
