Title: Stable breaker-crosslinker-polymer complex and method of use in completion and stimulation
Inventor: THOMPSON JOSEPH E SR
IPC: C09K8/68
Filed: 1997-04-22
Abstract: A preferred novel breaker-crosslinker-polymer complex and a method for using the complex in a fracturing fluid to fracture a subterranean formation that surrounds a well bore by pumping the fluid to a desired location within the well bore under sufficient pressure to fracture the surrounding subterranean formation. The complex may be maintained in a substantially non--reactive state by maintaining specific conditions of pH and temperature, until a time at which the fluid is in place in the well bore and the desired fracture is completed. Once the fracture is completed, the specific conditions at which the complex is inactive are no longer maintained. When the conditions change sufficiently, the complex becomes active and the breaker begins to catalyze polymer degradation causing the fracturing fluid to become sufficiently fluid to be pumped from the subterranean formation to the well surface.

Title: Paint drying furnace
Inventor: UMEDA HISASHI
IPC: B05C9/14
Filed: 1996-10-02
Abstract: This invention relates to a paint drying furnace for baking and drying paint films on painted objects following a painting process.     A conventional furnace discharges, from the system, combustion gas retaining a large amount of heat after a heat exchange in a combustion type furnace interior heating device with a gas circulating through a furnace interior circulating gas passage, and thus involves a great heat loss.       In this invention, a shunt gas passage (21) is provided for dividing a gas (PA) outputted from inner gas passages (ip) of a radiator means (7), from a position of a radiator circulating gas passage (20) upstream of a connecting point of a fresh air passage (18a), and mixing this divided gas (PA") into the gas (RA) circulating through the furnace interior circulating gas passage (9a).  With provision of this shunt gas passage (21), a combustion type radiator heating device (19a) acts also as furnace interior heating means (Ha). Thus, the above problem of the prior art is eliminated.
