Title: Hydraulic drive for rotation of a rock drill
Inventor: BAIDEN GREGORY R
IPC: E21B1/00
Filed: 1997-09-08
Abstract: The invention provides an In-The-Hole hydraulic drive unit for rotating a rock drill. A hydraulic motor having a fixed rear trailing end and a rotating front drilling end converts hydraulic power into a rotational drive force. The hydraulic motor receives high pressure hydraulic fluid through a receiving inlet and discharges lower pressure hydraulic fluid through a hydraulic outlet. A drive shaft connected to the rotating front drilling end is disposed within the hydraulic motor. A fluid transfer conduit within the drive shaft transfers hydraulic or pneumatic drill fluid to power the rock drill. The fluid transfer conduit bypasses the hydraulic motor for independent supply and operation of the rock drill. The fluid transfer conduit receives the drill fluid from the surface and transfers the drill fluid toward the rock drill. The drive shaft contains a drill rotator attached to the front drilling end adapted to receive and rotate the rock drill.

Title: Molecules amphipathiques agissant comme inhibiteurs de l'absorption du cholesterol et d'autres lipides
Inventor: BOFFELLI DARIO
IPC: A61K31/00
Filed: 1997-03-27
Abstract: La biosynthèse du cholestérol peut être inhibée par des inhibiteurs appropriés, tels que les statines. Cependant, l'hypercholestérolémie, qu'elle soit génétiquement transmise ou due au régime alimentaire, et plus généralement l'hyperlipidémie, ne peuvent être adéquatement traitées par les inhibiteurs de la biosynthèse du cholestérol uniquement, dans la mesure où le cholestérol dans le corps est produit par absorption à partir des aliments aussi bien que par synthèse endogène. Les lipides sont également absorbés à partir des intestins. On peut résoudre ce problème en utilisant une ou plusieurs molécules dotées de régions amphipathiques pour inhiber l'absorption du cholestérol et d'autres lipides de l'intestin. L'obésité, ainsi que l'athérosclérose, peuvent également être traitées ou prévenues de cette façon. On peut citer, comme exemples des molécules appropriées dotées de régions amphipathiques, les apoprotéines naturelles ou leurs variants, ainsi que d'autres protéines et peptides présentant une hélice .alpha. amphipathique composée d'au moins 15 acides aminés environ.

Abstract: A process, with methods and technologies to reduce green house gases, This intellectual property consists of the ideal hybrid seeds, machines, system and technologies to produce and convert to sustainable cost effective alternatives to the burning of fossil fuels and forest clear cutting, while providing energy, pulp for paper and lumber.   This process utilizes extensive comparison studies conducted internationally by universities, corporations and governments. Crossed, intermingled combinations of the above effectiveness have been organized to create a new original scientific approach for cost effective results. Old expired patents indirectly chosen for their single advantages have also been re-formulated to compliment and enhance the usefulness of the goal to reduce CO2 emissions worldwide. The formula for this chain combination invention stems from seeds, to maximum ethanol production yields.   This process includes stripping the hybrid sweet sorghum stalks seven to eight feet tall, into its fibrous and liquid composition, including the capture of its flower grain top. The method of application to achieve this task, consists of hand or machine knives, that remove the fiber stalk. The knives have scrapping edges, to remove the interior. The interior juice of this plant is fermented and distilled to produce ethanol. The heat required to cause distillation comes from waste material (leaves). This energy free waste provides low cost ethanol (alcohol). The shell stalk fibrous material is pulverized to make pulp for paper or compressed lumber alternatives.   The flower top is processed for foods such as grain cereal, bread or animal feed. Distillation systems consists of continued fermentation and distillation of the crop leaves and other waste materials through triple injection furnace burners. This triple injection furnace heat source accomplishes clean exhaust emissions. This furnace is used to produce alcohol for fuel; using clean combustion for distillation. Once produced, the clean renewable ethanol is used as fuel in conventional engines. A conversion kit, consisting of a supplementary pump, tank and hoses is installed on engines. The surplus pump kit, allows alcohol to replace gasoline at equal BTU demands. A separate injection system controls the dual injectors via computer signal to the engine.   Based on the combination of the above processed, methods and technologies the emissions are guaranteed to be reduced.
