摘要:
An internal combustion engine having an exhaust gas recirculation device for recirculating exhaust gas of the internal combustion engine to a fresh-air side of the internal combustion engine. For this purpose, it is provided that the exhaust gas recirculation device has at least one compressor for compressing the exhaust gas supplied to the fresh-air side of the internal combustion engine.

A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit.
摘要:
A method for operating an internal combustion engine (10) having a steam power plant (12), in which the exhaust gas of the internal combustion engine (10) at least indirectly heats the steam and this steam drives a turbine (26), the steam power plant (12) being sometimes, in particular at the beginning of operation, initially operated in a protection operating mode, in which the protection of the turbine (26) from damage by water droplets has priority.
摘要:
A biased support for booms that can pivot about a pin, for pivoting travel tracks for vehicles that run on rails, such as trolley travel tracks on booms. The booms are mounted to pivot via pins, the lock on the boom and slide plates on the upper and lower bearing points of the lock. At least one of the two slide plates in the upper bearing point is mounted elastically, so that when the boom is pivoted into the operating position, the entire lock is biased vertically and the pin is relieved of stress.

The colorants for keratin fibers are based on oxidation dye precursors and/or direct dyes and contain a combination of (a) at least one nonionic, amphiphilic associative thickener, (b) at least one fatty alcohol that is liquid at 25° C. and (c) PEG-150/stearyl alcohol/SMDI copolymer in a suitable cosmetic carrier.
摘要:
The invention relates to a system to regulate the heat balance of a vehicle, with a heat cycle that dissipates engine heat, which features a cooling circuit (38) and a heating circuit (36), through which circuits a coolant can flow, and with at least one component (20) of the vehicle producing waste heat, wherein a system is provided with which the waste heat of at least one component of the vehicle can be transferred to the heat cycle.
摘要:
A method for training a neural network in order to optimize the structure of the neural network includes identifying and eliminating synapses that have no significant influence on the curve of the risk function. First and second sending neurons are selected that are connected to the same receiving neuron by respective first and second synapses. It is assumed that there is a correlation of response signals from the first and second sending neurons to the same receiving neuron. The first synapse is interrupted and a weight of the second synapse is adapted in its place. The output signals of the changed neural network are compared with the output signals of the unchanged neural network. If the comparison result does not exceed a predetermined level, the first synapse is eliminated, thereby simplifying the structure of the neural network.

A valve arrangement including a distributor housing (2) with a distributor duct (4), an inlet duct (46) which leads into the distributor duct (4), at least two outlet ducts (11, 12, 13) which lead out of the distributor duct (4), and a value associated with eac;h outlet duct. The values are integrated into the distributor housing (2) and have regulating flaps (31, 32, 33) whose axes of rotation (37, 38, 39) are arranged such that the flaps are situated partially in the distributor duct (4) and partially in the associated outlet duct (11, 12, 13). This construction reduces the overall size of the valve arrangement and eliminates dead spaces in which medium flowing through the valve arrangement could become trapped.
摘要:
In a spring-loaded safety valve for gas and vapor, a valve disk which faces a valve seat and is movable to open or close the valve is provided with a deflecting collar which includes at an inner face thereof overlapping the valve seat two cone portions smoothly connected to each other by radii.
摘要:
A safety valve has movable and immovable valve elements, and a friction unit arranged therebetween for damping vibrations, wherein the friction unit has a plurality of friction members movable radially relative to a valve axis, a pressing member arranged to move the friction members so that their friction surfaces are pressed against a friction countersurface of a movable valve element of the movable valve means and for abutment against a stationary abutment member at their side facing toward a valve closing member, and a pretensioned auxiliary spring acting upon the friction members at their side facing away from the valve closing member and in a valve closing direction, wherein the auxiliary spring has such force and such a smaller resistance that in the event of seizing of the friction members with the movable valve element, the auxiliary spring is compressed within a predetermined opening pressure which does not considerably exceed a response pressure over approximately a valve stroke.
