Title: Pulsed in situ exothermic shock wave and retorting process for hydrocarbon recovery
Inventor: PRICE ERNEST H
IPC: E21B43/247
Filed: 1990-01-29
Abstract: PULSED IN SITU EXOTHERMIC SHOCK WAVE AND RETORTING PROCESS FOR HYDROCARBON RECOVERY          ABSTRACT        An active combustion zone is established in situ within a permeable hydrocarbon formation.   The permeable formation is periodically charged with a combustible gas mixture,  and  is thereafter subjected to a high pressure pulse produced by detonation of the combustible gas mixture within an injection well.   The combustible gas mixture is displaced through the permeable formation in advance of the combustion flame front in response to a high pressure pulse produced by detonation of the pressurized combustible gas mixture within the injection well.  In the preferred embodi-ment, the combustible injection gas is a mixture of hydrogen gas and chlorine gas.  As the hydrogen/chlorine gas mixture undergoes combustion, a large volume of high pressure, high temperature hydrogen chloride gas is produced, together with an aqueous solution of hydrochloric acid.  The hydrochloric acid is forced into the surrounding permeable formation, and reacts with the carbonaceous materials to separate nitro-genous, sulphurous and arsenic compounds from the liquid oil product.

Title: Halpen helix and ribbon cables
Inventor: HALPENNY ARTHUR S
IPC: H01B7/08
Filed: 1990-07-19
Abstract: ABSTRACT   A method of manufacturing a ribbon cable consisting of a multiplicity of insulated wires, and non-insulated wires and holding them in place by use of an adhesive polymer or elastomer, which has varying lengths of setting or harding times. One of the primary designs is the formation of the ribbon cable into a helix pattern which will enable it to expand and retract longitudinally without significant diameter changes, and always return to its original state.  The same technique can be used to form a ribbon cable in a flat pattern once again with a multiplicity of conductors held together by an adhesive coating.  These cables exhibit extraordinary attributes when exposed to environmental hazards such as high temperature, mechanical abuse and radiographic attack.

Title: Method of treating a ferrous component for subsequent metallurgical bonding to cast aluminum
Inventor: GUENTHER WILLIAM D
IPC: F02B23/06
Filed: 1990-08-29
Abstract: ABSTRACT OF THE DISCLOSURE The present invention concerns a method of treating a ferrous component, such as a cast iron cylinder liner, for subsequent metallurgical bonding to cast aluminum, such as an engine block.  Initially, the cast iron cylinder liner is cleaned of grease, oil, and oxides, and is then immersed in a bath of molten aluminum at a temperature in the range of 1100-1500°F, for a time period sufficient to form an Fe-Al intermetallic compound layer adjacent the surface thereof.  As the cylinder liner is removed from the aluminum bath, a thin molten aluminum coating will cover the liner, and an aluminum oxide film immediately begins to form thereon.  In accordance with the present invention, immediately after the liner is removed from the aluminum bath, and while the aluminum coating on the liner remains molten, the liner is quenched in a zinc alloy bath at a temperature in the range of 720-1000°F.  When the liner is immersed in the zinc alloy bath, the aluminum oxide film on the surface of the molten aluminum coating will wash away and float to the surface, thereby leaving a protective zinc coating on the liner which prevents the formation of any further oxides.  The zinc coating will remain on the liner until the aluminum casting operation, at which time the zinc will wash away and alloy with the cast aluminum, thereby ensuring a metallurgical bond between the liner and the casting.
