摘要:
In a space shuttle with a device for docking to a satellite, especially a communication or navigation satellite, at least two spreading elements in the form of lever spreaders (4) are pivotally disposed at a retaining part (3) of the docking device, which is concentric to a linkage (2). The lever spreaders (4) have their proximal ends—relative to the space shuttle—provided with noses (41) projecting inward towards the linkage (2), which noses engage in a recess (22) formed in the linkage (2) when the lever spreaders (4), spread apart to a defined opening angle by the cone (21) of the linkage (2), are retracted.When the linkage (2) is retracted further, a pressure spring (5) is compressed. At the same time, the lever spreaders (4) caught in the recess (22) are retracted so far that the ends (42) of the lever spreaders (4), spread apart in a defined manner, positively abut the inner wall of the nozzle neck (10)

The invention relates to a coupling system (12) which is used to connect a tube (7) to a socket (8). Said tube (7) comprises a support (13) which is arranged on at least one or the ends thereof. Said support can be inserted into the socket (8) and the comprises, on the external side thereof, at least one annular groove (14) and a securing contour (16). The socket (8) comprises a stop contour (20) on the external side thereof. A coupling element (17), which is produced separately in relation to the socket (8) and the support (13), is placed on the outside on the support (13). The coupling element (17) comprises at least one stop hook (19) which engages behind the stop contour (20) when the support (13) is inserted into the socket (8). The coupling element (17) comprises at least one securing hook (18) which co-operates with the securing contour (16) in order to fix the coupling element (17) to the support (13) in an axial manner.

An internal combustion engine includes multiple combustion chambers. The supply of fuel into at least one subset of the combustion chambers can temporarily be interrupted. It is provided that the fuel be injected into the combustion chambers directly and during a switchover phase for interrupting or resuming fuel injection into the subset of combustion chambers, at least temporarily via multiple injections.

A method for generating a flexible display field on a monitor includes providing a display field with a main window, into which a plurality of information windows are incorporatable and which has a basic grid with a regular raster, allocating individual grid fields to a respective information window for displaying in an assigned grid field, setting a grid stage of a basic field via a central first user control device for the main window, switching the main window between a regular grid occupancy in which a size of each incorporated information window corresponds to a size of one grid field of the basic field, and an irregular grid occupancy in which a size of at least one information window corresponds to a size of an integral multiple of one grid field of the basic grid, and initiating a switchover of a user by a selection and a change in size of an information window and also a video management system and a software program are provided.

Disclosed is a simple, easy-to-produce, and reliable connection between a shaft of a gas exchange valve and an actuator. This connection is detachable and, as a result, can be connected and disconnected multiple times. It is also possible to dispose the coupling piece on the shaft of the gas exchange valve and provide circumferential grooves on the control element of the actuator 5.

The present invention relates to a connection between a shaft end of a gas exchange valve of an internal combustion engine and a sleeve-shaped actuating element of a valve actuator, which is guided in an axially movable manner within a pressure region, which is able to be pressurized with a pressure medium, of the valve actuator and at least partially surrounds the shaft end. The present invention provides for the connection to be situated outside of the pressure region and in the region of an opening, which is formed on the side of the valve actuator away from the combustion chamber, and is, for example, coaxial to the shaft end.

The invention relates to a transloading apparatus for transcontainers such as freight containers, interchangeable containers and semi-trailers including a crane trolley adapted to travel on a crane or portal, to which, by way of a lifting means, a load receiving means is fitted in a manner for raising and lowering. In order to enable the load receiving means to be guided and aligned more accurately in relation to the transcontainer, provision is made to connect to the load receiving apparatus two horizontally movable columns or lifting structures at a distance from one another which is fixed or can be adjusted in a defined manner and to reader these vertically displaceable. Preferably each of the columns or each of the two lifting structures can be connected by way of a pendulum suspension to the load receiving means.

A light grid consists of a row (13) of adjacent light transmitters (11.sub.i) and adjacent light receivers (12.sub.i) arranged at a distance opposite to the latter. The light transmitters (11.sub.i) and the associated light receivers (12.sub.i) are individually activated cyclically one after the other. A determination is made at each light receiver (12.sub.i) whether a received light signal is present or not on activation of the associated light transmitter (11.sub.i). By considering, during the evaluation, the light receivers (12.sub.i-1, 12.sub.i+1) adjacent to the associated light receiver (12.sub.i) and the light transmitters (11.sub.i+1, 11.sub.i-1) adjacent to the associated light transmitter (11.sub.i), a differentiation is made between an obstacle introduced into the protective field (26) and a defect light transmitter (11.sub.i) and/or light receiver (12.sub.i).

The present invention relates to a device for generatively manufacturing a three-dimensional object (3), comprising: a frame (1) defining a building field (6) at an upper portion (2) thereof; a plate (12) which connects the frame (1) with a housing (100) of the device; a support (5) which is arranged in the frame (1) and vertically movable by a lift mechanics (4) at least below the building field (6); a radiation device (7) which generates an energetic beam (8, 8′) which is focused by a deflection means (9) to arbitrary points in the building field (6), so as to selectively sinter or melt a powdery material (11) which is present in the building field (6); a coater (10) for applying a layer of powdery material (11) onto the support (5) or a previously applied layer of the powdery material (11). A thermal insulation (13) is arranged between the frame (1) and the plate.
