Title: Hot fuel gas generator

IPC: F02M31/12

Granted: 1979-05-29
Abstract: HOT FUEL GAS GENERATOR A hot fuel gas generator for an internal combustion engine vaporizes gasoline and water in a heated pressure vessel and mixes the resulting superheated gaseous fuel with air in a metering valve which communicates with the internal combustion engine. A single device operating at a very high temperature, for example 1000 F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature gaseous state of the fuel represents molecules at the greatest degree of separation from each other providing the greatest opportunity for contact of the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction. The fuel gas produced therefore enables complete combustion and the elimination of the atmospheric pollutants common in the operation of internal combustion engines. This invention distinguishes from other inventions by reason of high temperature simultaneous vaporization of the Fuel and water to develope a desirable working pressure and volume of gas for the operation of an internal combustion engine.

Abstract: Abstract of the Disclosure A brake cooling circuit which includes a pump for circulating cooling fluid to the brakes in a scraper portion of a tractor scraper combination is driven by a motor powered by hydraulic fluid communicated through conduits leading to one of the implements of the scraper.  Selective actuation of the brake cooling circuit may be accomplished manually by the operator.  Automatic actuation of the brake cooling circuit is also provided upon a signal of a high temperature condition in the brakes.  The vehicle hydraulic circuit is designed to override the cooling circuit upon actuation of the implement by the operator.  Upon completing of the work cycle of the implement, the cooling circuit is reactuated.  The cooling circuit is comprised of the motor driving the pump and the fan, a radiator, conduits for communicating cooling fluid through the radiator and to the brakes, a control assembly, and a separate source of cooling fluid.  In the control assembly, vehicle air pressure is used to operate a series of valves to divert a limited flow of pressurized hydraulic fluid from the implement circuit to run the motor.

Abstract: CONTROL SYSTEM FOR PECK DRILLING TOOL                    ABSTRACT OF THE DISCLOSURE          An automated and adjustable control system for conducting peck drilling operations wherein a drill bit is advanced stepwise in successively increasing penetrations, rapidly retracted after each penetration to remove cuttings, thereafter rapidly advanced toward a work face and then slowed to a drilling advanced rate beginning with the bit a predetermined distance from the work face.  Preferably, a pneumatic means rapidly retracts the drill upon completion of each penetration step.  A feed rate control unit is partially retracted but limited to a distance less than retraction of the drill.  When the drill is rapidly advanced by pneumatic means during each penetration step, the feed rate is decreased by the feed rate control unit to a uniform drilling rate prior to engaging the work face in the work piece.

Abstract: La préparation de dérivés d'acides perfluoroalcane carboxyliques et d'acides perfluoroalcane sulfiniques est effectuée par réaction d'un halogénure de perfluoroalkyle RFX où X représente un atome de chlore, brome ou iode et RF une chaîne perfluorée linéaire ou ramifiée comportant de 2 à 12 atomes de carbone avec du CO2 ou du SO2, en milieu solvant et en présence de zinc activé ou non.  Les dérivés des acides perfluorocarboxyliques obtenus selon ce procédé peuvent être facilement transformes en acides perfluorocarboxyliques libres RF COOH. Les dérivés des acides perfluoro-sulfiniques peuvent être transformés selon des méthodes connues en dérivés des acides perfluoroalcane-sulfoniques.  Ainsi, par oxydation par l'eau oxygénée, il est possible d'obtenir les sels des acides perfluoroaulfoniques et par chloration, les chlorures de perfluoroalcane-sulfonyle RFSO2Cl qui peuvent à leur tour être transformés en acides perfluoroaulfoniques RFSO3H.  Ces dérivés revêtent un intérêt industriel incontestable.  Ils peuvent être utilisés soit en tant qu'acides (RFCOOH ou RFSO3H) comme agents mouillants ou surfactifs, mais ils peuvent aussi être utilisés comme matière intermédiaire pour la fabrication d'agents de traitement des textiles, du cuir et du papier, ou pour la fabrication de produits ayant des propriétés tensio-actives.

Abstract: METHOD AND APPARATUS FOR NEUTRON INDUCED GAMMA RAY LOGGING FOR LITHOLOGY IDENTIFICATION           Abstract of the Disclosure.  A pulsed neutron generator in a well logging instrument is pulsed at a clock frequency of 20 KHz.  Inelastic scatter gamma rays are detected during a first time interval coinciding with the neutron source being on and capture gamma rays are measured during a second interval subse-quent to the end of each neutron burst.  Only a single detected pulse, assuming detection occurs, is transmitted during each of the two detection intervals.  Sync pulses are generated in the well logging instrument scaled down to a frequency of 200 Hz for transmission to the earth's surface.  At the earth's surface, the scaled-down sync pulses are applied to a phase-locked loop system for regenerating the sync pulses to the same frequency as that of the clock frequency used to pulse the neutron source and to open the detection gates in the borehole instrument.  The regenerated sync pulses are used in the surface instrumentation to route the pulses occurring in the inelastic interval into one section of a multichannel analyzer memory and the pulses occurring in the cap-ture interval into another section of the multichannel analyzer.          The use of memory address decoders, subtractors and ratio cir-cuits enables both a carbon/oxygen ratio and a silicon/calcium ratio to be struck, substantially independent of the chlorine content of the borehole and formation.     -1a-
