Abstract:
In an internal combustion engine with a cooling system and an exhaust gas recirculation (EGR) system including an EGR heat exchanger with a coolant inlet opening connected to a coolant outlet opening of the engine for receiving coolant therefrom and the engine including a coolant collecting rail mounted directly to the engine and having a coolant inlet opening connected to the EGR heat exchanger and at least one other coolant inlet opening in communication directly with at least one other coolant outlet opening of the engine.
Abstract:
A charging device for a tube reactor has a plurality of metering chambers which can be filled with filling material, for example a catalytically coated carrier material. Each metering chamber is adjoined by a drop tube or some other filling device via which a tube of the filling device can be filled in each case. The metering chambers can each be filled via antechambers which are combined into one replaceable antechamber unit.
Abstract:
In an arrangement for handling the fuel in a common rail fuel injection system of an internal combustion engine, wherein fuel is supplied from a tank via a fuel delivery line including a first fuel filter, a low-pressure pump arranged upstream from the first fuel filter and a high pressure pump arranged downstream of the first fuel filter to a high pressure fuel rail from which the fuel is distributed to the cylinder of the engine, a bypass line extends from the high pressure fuel rail to the fuel delivery line and includes a second fuel filter and a heat exchanger which is operatively connected to a cooling circuit of an air conditioning system or to a cooling circuit of the internal combustion engine.
Abstract:
What is described are N-[pyrimidin-2-ylmethyl]carboxamides of the formula (I) and their use as herbicides. In this formula (I), X1 and X2 are hydrogen or methyl, R1 to R4 are various radicals and A is an aromatic or heteroaromatic ring.
Abstract:
The invention relates to a method for desulfating a nitrogen oxide storage catalyst that contains stored nitrogen oxides and sulfur oxides and that forms part of an exhaust gas purification system of a lean-burn engine. The method provides that, to initiate desulfation, the temperature of the catalyst is increased to the point where thermal desorption of the nitrogen oxides stored in the catalyst sets in, and the onset of thermal desorption of the nitrogen oxides is used as the signal to enrich the air/fuel mixture to perform the desulfation.
Abstract:
The invention concerns oligosaccharides and polysaccharides as well as the use of these oligosaccharides and/or polysaccharides, which contain the sugar unit N-acylglucosamine or N-acylgalactosamine for the production of hemocompatible surfaces as well as methods for the hemocompatible coating of surfaces with said oligosaccharides and/or polysaccharides, which imitate the common biosynthetic precursor substance of heparin, heparan sulphates and chitosan. The invention further describes methods for producing said oligosaccharides and/or polysaccharides and discloses various possibilities of using hemocompatibly coated surfaces. The invention relates particularly to the use of said oligosaccharides and/or polysaccharides on stents with at least one according to invention deposited hemocompatible coating, which contains an antiproliferative, antiinflammatory and/or antithrombotic active agent, methods for the preparation of said stents as well as the use of said stents for the prevention of restenosis.
Abstract:
The invention relates to anti-thrombogenic surfaces and a process for making said surfaces. The process is primarily used for the anti-thrombogenic coating of hydrophobic surfaces of medical products coming into direct contact with blood and coagulable blood products.
Abstract:
An integrated circuit for generating targeted bitlength manipulation of a transmitter for output of a serial datastream. A control unit (5) provides instructions regarding respective partial bits in a form of a partial bit vector (7) depending on bit statuses to be sent, and determines bitlengths for the serial datastream for output (9) to a wire or a signaling converter. The datastream (9) is generated using two partial bit register chains (14a-d, 15a-d), whose serial outputs (16, 17) are connected using a joining gate.
Abstract:
A cable comprising a stress-bearing matrix extending substantially through the length of the cable; and a plurality of conducting elements extending substantially through the length of the cable, the plurality off the conducting elements being located within and spaced from one another by the stress-bearing matrix, wherein at least one of the plurality of conducting elements is in intimate contact with a low friction liner disposed about at least one of the plurality of conducting elements, and the at least one of the, conducting elements is longitudinally moveable relative to the stress-bearing matrix.
Abstract:
Thermoplastic multilayer composite, particularly in the form of a multilayer hose, a multilayer pipe or a multilayer container, containing at least one intermediate layer made of a molding compound on the basis of ethylene/vinyl alcohol copolymers between layers made of molding compounds on the basis of polyamide, the intermediate layer being bonded via at least one adhesion-promoting layer made of a molding compound on the basis of polyamide selected from the group of copolyamide 6/12, block copolyamide 6/12, polyamide 612, polyamide 610, a mixture of polyamide 6 and polyamide 12 with compatibilizer, a mixture of polyamide 6 and polyamide 11 with compatibilizer, with at least one neighboring layer made of a molding compound on the basis of polyamide 12, polyamide 11, polyamide 1010, polyamide 1012, or polyamide 1212.
