Abstract: The injector tip of an injection valve which injects directly into the combustion chamber protrudes therein, thereby incurring the risk that combustion residues can become deposited on the injector tip. When the injection valve is in a closed state, the possible attachments of combustion residues along a separation line (10) are eliminated by means of a special configuration of the surface at the separation line (10) between the valve body and a valve plate. The surface is represented in a smooth, step-less, edge-less and curved manner.

Abstract: The invention relates to a gateway for connecting telecommunications networks, and to an associated method, in which a user channel data converter is connected via at least one additional user channel data interface to a switching center, and a signaling channel data converter is inserted between an already existing user/signaling channel data interface such that signaling information (SD(cic4)) which is transmitted on this data interface is filtered out for the additional user channel data interface. This results in a connection for a packet-switching telecommunications network without any major intervention in the network structure of a line-switching telecommunications network.

Abstract: A device for controlling drives of machine tools or production machines is disclosed, whereby the device includes a permanent storage medium associated with the device and a trace module that records actual process values after the trace module is triggered. The actual process values are permanently stored on the permanent storage media in form of files in a standard file format. The device makes it possible to permanently store actual process values recorded by a trace functionality, in particular by a trace module, in the device for controlling drives in a standard data format.

Abstract: In fuel reservoir injection systems also known as common rail fuel-injection systems (1) for motor vehicles the problem exists that for a defined quantity of fuel that is about to be injected it is necessary to take into account not only the predominant pressure of the fuel but also its temperature. It is difficult to install and use a temperature sensor to detect the fuel temperature. The invention therefore proposes a method and a device for determining the temperature (T) from the pressure (P) measured by the pressure sensor (4) and the sound-propagation velocity (V) of a shock wave triggered at the moment of injection.

Abstract: A messaging system (300) capable of handling threaded messages. Older messages (400, 402) in a thread may be identified as having already been read or opened, and handled in the same way as later messages (404) in the thread. If a user opens an intermediate message (402) in a thread, he is informed of the presence of a more recent message (404) on the same topic and is offered the chance to open that message instead.

Abstract: Aspects of the invention relate to a method for facilitating the reduction of carbon monoxide emissions during part load operation of a turbine engine by holding high combustor temperatures. The combustor section of the turbine engine includes a plurality of combustors, each combustor having a pilot nozzle, a plurality of main nozzles circumferentially surrounding the pilot nozzle, and a premix ring. According to one aspects of the invention, a first pair of combustors are selected. Fuel can be substantially restricted from being supplied to the main nozzles and the premix ring of the selected combustors, while fuel continues to be supplied to the pilot nozzles of the selected combustors. Additional combustors can be selected and the supply of fuel can be selectively restricted as described above. The process can continue until there is substantially zero net power out of the engine.

Depending on the measured vacuum the conveyor means can be controlled such that the front object has an inclination as low as possible with the lowest possible stack pressure on the at least one friction picking device.

The closing member has a second position where the closing member opens the port and allows fluid communication between the intake passage and the vapor purge passage and extends into the fluid stream of the intake passage when fluid is flowing through the intake passage. The actuator assembly drives the closing member between the first and second positions.

The channels of the beam detector each have a detector element with channel electronics connected downstream thereform. The signal of the defective channel is restored while using neighboring signals of an M-neighborhood of the same projection and from adjacent signals of an M-neighborhood of additional projections.

Abstract: A fuse link, especially for low voltage, high-breaking-capacity fuses, includes at least one fusible conductor having a soldering substance in a solder depot of a carrier, the solder being tin-based and the carrier being copper-based. The solder contains a tin alloy as an active substance, the tin alloy having two other constituents. The first constituent, which is the larger of the two in weight percent but which is smaller in weight percent than the proportion of the base substance tin, is selected for lowering the fusion temperature of the solder. The second constituent, which is the smaller of the two in weight percent, is a substance which does not dissolve in tin. Crystal nuclei are formed when said substance is cooled from the liquid state to the solid state, creating a fine structure and preventing the structure from becoming coarse under a load.
