20080202724 | Exhaust Gas Heat Exchanger and Sealing Device for the Same - The invention relates to exhaust gas heat exchangers, as they are generally known, and to a sealing device which is especially suitable for using in exhaust gas heat exchangers. The inventive exhaust gas heat exchanger comprises connection points for the exhaust gas flow, for connecting the exhaust gas heat exchanger both to an exhaust gas supply line for supplying a hot exhaust gas and an exhaust gas withdrawal line for withdrawing the exhaust gas flow cooled in the exhaust gas heat exchanger. The exhaust gas flow flows through the exhaust gas heat exchanger in a bundle of exhaust gas guiding pipes in a flow direction. A coolant also flows through the exhaust gas heat exchanger, in a coolant flow. To this end, the exhaust gas heat exchanger is provided with at least one coolant supply connection and at least one coolant withdrawal connection. The coolant is guided in a coolant channel in the exhaust gas heat exchanger, inside which it flows around the bundle of exhaust gas guiding pipes. According to the invention, the coolant channel comprises at least two regions which differ in terms of the flow direction of the exhaust gas flow by divergent flow directions of the coolant. | 08-28-2008 |
20090133660 | VALVE, ESPECIALLY ROTARY PISTON VALVE, AND EXHAUST GAS RETURN SYSTEM COMPRISING SUCH A VALVE - The invention relates to a valve, especially a rotary piston valve ( | 05-28-2009 |
20100263610 | SWITCHABLE WASTE GAS EXCHANGER - The invention relates to switchable waste gas exchangers which can are arranged and used, in particular, in exhaust gas recirculation lines in internal combustion engines, especially in motor vehicles. | 10-21-2010 |
20130269652 | FOUR-STROKE INTERNAL COMBUSTION ENGINE COMPRISING AN ENGINE BRAKE - A four-stroke internal combustion engine having an engine brake, at least one exhaust valve per cylinder, each valve actuated by a camshaft and at least one first valve lever arrangement, and a device which advances the exhaust control, with the valve lever arrangement having an exhaust lever actuated by an exhaust cam and a brake lever actuated by a brake cam. The brake lever has a first brake lever part on the side of the camshaft and a second brake lever part on the side of the exhaust valve, with the two brake lever parts being rotatably mounted independent of each other about a lever axis and being rotationally connectable with each other in engine braking operation by a locking element which is adjustable between two positions. | 10-17-2013 |
20150034029 | INTERNAL COMBUSTION ENGINE HAVING AT LEAST ONE CYLINDER - An internal combustion engine having at least one cylinder with a reciprocating piston, and in which the cylinder head and the cylinder block are integrally arranged as a head-block unit, having at least one exhaust-gas turbocharger. | 02-05-2015 |

20090026956 | COILED COIL ELECTRODE DESIGN FOR HIGH PRESSURE SODIUM LAMPS - A high pressure sodium discharge lamp includes an arc tube which encloses a discharge sustaining fill which comprises sodium. Electrodes extend into the fill for generating an arc discharge in the fill during operation of the lamp. At least one of the electrodes includes a coiled coil which supports an emitter material thereon. | 01-29-2009 |
20090146570 | LANTHANIDE OXIDE AS AN OXYGEN DISPENSER IN A METAL HALIDE LAMP - A lamp includes a discharge vessel. Tungsten electrodes extend into the discharge vessel. An ionizable fill is sealed within the vessel. The fill includes a buffer gas and a halide component that includes a rare earth halide. A source of oxygen which includes a lanthanide oxide is present in the discharge vessel. The source of oxygen provides oxygen for a regenerative cycle which reduces blackening of the lamp walls by tungsten from the electrodes. | 06-11-2009 |
20130127336 | INFLUENCE OF INDIUM IODIDE ON CERAMIC METAL HALIDE LAMP PERFORMANCE - The present disclosure relates to a discharge lamp with improved color point, Dccy and CRI. More specifically, the invention provides a ceramic metal halide (CMH) lamp exhibiting improved color point, Dccy and CRI with little or no loss in other lamp performance parameters. For example, the lamp in accord with at least one embodiment of the invention exhibits excellent lumen output, lamp CCT, and efficacy, in addition to improved color parameters. In one embodiment, the lamp demonstrating these characteristics is a CMH lamp having low levels of indium iodide included in the dose thereof. | 05-23-2013 |
20140175975 | CERAMIC METAL HALIDE LAMPS WITH CONTROLLED COLD SPOT - Apparatus and methods for controlling the cold spot in a high-intensity discharge lamp. In an embodiment, an elongated arc tube has an inner wall defining a discharge chamber that includes a metal halide dose. A first leg extends from the arc tube in a first direction and a second leg extends from the arc tube in a second direction that is opposite the first direction. The first electrode is disposed within the first leg such that no voids exist between the first electrode and an entire inner portion of the first leg. Likewise, a second electrode disposed within the second leg has no voids between it and an entire inner portion of the second leg. The arc tube also has a first annular bucket structure within the discharge chamber formed by a nub surrounding the first tip and an interior wall portion, and a second annular bucket structure within the discharge chamber formed by a nub surrounding the second tip and a second interior wall portion. As a result, when the high-intensity discharge lamp is in a vertical operating position a cold spot is formed in one of the first and second annular bucket structures. | 06-26-2014 |
20150215744 | SYSTEM AND METHOD FOR INDOOR POSITIONING, NAVIGATION AND LOCATION SPECIFIC SERVICES - A system including a luminaire lens including a surface having a coded positional data pattern, a mobile communication device including a camera and a display screen, a database having data records representing a floor plan of a building or structure, the mobile communication device in communication with the database, and a mobile communication device application, the application configured to decode the coded positional data pattern and to locate the decoded positional data on the floor plan, wherein the decoded positional data is displayed on the display screen. A method includes providing a luminaire lens having a coded positional data pattern, decoding the positional data, locating the decoded positional data on the floor plan, and displaying the decoded positional data on a display screen. A non-transitory medium having executable instructions is also described. | 07-30-2015 |
