摘要： This invention is detailing a construction method for a cast in-situ pile having an upper section with a larger diameter and at least one subsequent section with a smaller diameter, and a drilling device equipped with continuous flights which allows the construction of one pile having multiple diameters using the innovative construction method in a single continuous drilling phase while each drilling tool is penetrating through the soil in one pass.
The drilling tool according to the invention has a central hollow space that allows accommodation through it of at least one another smaller diameter drilling tool that can drill continuously and can be coupled by means of a coupling-decoupling device in a specific manner to the other drilling tool in order to act as a fixed assembly, at any given position in relation to the smaller drilling tool length and rotating position.-

摘要： A moisture control apparatus for a cooking chamber of a cooking device. A cooking system that can include the cooking device and the moisture control apparatus connected to the cooking chamber of the cooking device. The moisture control apparatus can include a control portion and a dispersal portion. The control portion can be located on the outside of the cooking device. The control portion can control the flow of water to the dispersal portion so as to control moisture on a food in the cooking chamber of the cooking device by providing, by the dispersal portion, a mist or fog of water particles to the cooking surface of the cooking chamber. The dispersal portion can be located inside the cooking chamber of the cooking device, and the control portion can be located outside the cooking chamber of the cooking device.

摘要： Subterranean gas capture wellbores are used to capture lost produced gas. Produced gas can be injected into a subterranean for gas enhanced hydrocarbon recovery and rise in the subterranean formation toward a production wellbore. A first portion is effective for enhanced hydrocarbon recovery and a second portion rises past the production wellbore to become the lost produced gas that is converted to captured produced gas in the subterranean gas capture wellbore. The captured produced gas can then flow in the subterranean gas capture wellbore to the surface for recovery.

摘要： A medical syringe having a forwardly projecting needle that is selectively retractable following use and also having a specially configured plunger handle and thumb cap that cooperate to form a concave pressure application surface (“CPAS”). The concave pressure application surface at the rear of the plunger handle enables the subject medical syringe to achieve functional advantages, each with an associated therapeutic benefit, that are not achieved with use of the prior art devices.

摘要： Disclosed are alkyl lactone-derived hydroxyamides and alkyl lactone-derived hydroxyesters used in compositions and methods for inhibiting natural gas hydrate agglomerates. The alkyl lactone-derived hydroxyamides and alkyl lactone-derived hydroxyesters are reaction products of an alkyl lactone and an amine, and an alkyl lactone and an alcohol, respectively.

摘要： An improved radiator mounting and cooling system for use in automobiles allows multiple components to be incorporated into the same unit, limiting the need for accessories to be mounted to inner fenders or firewall. A circulating vortex of air is pulled through a front grill and vortex tubes disposed through sides of the radiator system to improve cooling efficiency. An outer shroud protects interior components and creates a sealed core cavity allowing air to only enter through vortex tubes and front grill and exit through a rear grill. A self-circulating cooling system provides additional cooling of coolant. A fan system pulls around 5000 CFM of air through the core cavity. An optional secondary coolant pumping system allows coolant to be pumped when needed. A control system controls activation of the fan system and secondary coolant pumping system based on signals from sensors.

摘要： A duplexer includes a cavity resonator defining an opening covered by an RF plate. The RF plate defines an opening through which a pass-band tuning pipe extends and is secured thereto. A collar is attached to one end of the pipe, and at least one steel set screw extends into the interior of the collar, the at least one end having a soft (e.g., brass) tip. A tuning plunger is slidingly positioned within the pass-band tuning pipe. A rod is attached to a first end of the tuning plunger and extends through the collar, the rod being fabricated from a material harder than the tip of the at least one set screw. The at least one set screw is configured for tightening down on the rod to secure the rod and tuning plunger in place. A trimmer capacitor is positioned in the RF plate.

摘要： Universal simulator used to practice techniques and procedures in cardiac surgery through classical and minimally invasive approaches at the heart level, or other interventions in the thoracic surgery field. The simulator is composed of a synthetic thorax (1) which has several incisions (6) with mobile costo-vertebral joints (2) and mobile sterno-costal joints (3), a sternum with a medium cut (4) and a transversal cut (5) at the level of the third intercostal space, a porcine tissue composed of heart (7), two lungs (21), ascending aorta (17), descending aorta (22) and trachea (23) and a pumping system composed of an actuator (10), a piston cylinder (8) connected through tubing (11) to the left and right ventricles of the heart, a variable pressure pump (9) which pumps liquid through tubing (18) into the ascending aorta (17), an air trap (13) mounted between the pump (8) and the heart (7) and two unidirectional valves (19 and 20) for liquid and air, mounted in series in the superior part of the air trap (13) and a reservoir (14) for liquid connected to the pumps (8 and 9) which pump liquid into and from the heart (7) and to the ascending aorta (17).

摘要： A system and method for simultaneously removing water and acid gases from methane in a single process without requiring dehydration prior to acid gas removal. A feed stream comprising these components and little or no hydrocarbons heavier than methane is separated in a series of separators, including an absorber column using methanol as an absorber. A treated methane stream comprising at least 90%, more preferably at least 95%, most preferably at least 99%, of the methane from the feed stream and an acid gas waste stream comprising less than 10%, more preferably less than 5%, most preferably less than 1%, of the methane from the feed stream are produced. Using methanol as a physical solvent allows removal of water and acids gases in a single step using substantially less energy than conventional separation methods. The system and method are particularly useful in treating landfill gas feed streams.
