摘要:
A process and apparatus are provided for generating at least two types of steam having different purities in steam reforming processes in which at least two steam reforming units (steam reformers) (are operated in parallel. The first steam stream having a higher purity than that of the second steam stream. The steam reformers operated in parallel are combined to form groups of at least two steam reformers (groups) within which the high purity steam is generated in one of the steam reformers by vaporization of degassed and demineralized water and low purity steam is generated in at least one of the other steam reformers by vaporization of degassed impurity-containing water (dirty water). The dirty water is formed at least in part from the condensate (process condensate) produced within a group, and is predominantly made up of water.

The invention relates to a distribution module for converting between symmetric and non-symmetric data transmission paths. Said distribution module comprises a housing in which a transformer is arranged for adjusting impedance, first contacts for connecting at least one non-symmetric data cable, and second contacts for connecting at least one symmetric data cable. The first and second contacts are disposed on opposite faces of the housin. The second contacts are embodied as at least one RJ45 plug-in connector.
摘要:
Carbon monoxide is generated carbon monoxide, in a conversion stage (DR), from a hydrocarbon-containing feed (1, 2), and also steam and/or carbon dioxide (CO2), resulting in the formation of a carbon monoxide (CO)—, hydrogen (H2)— and methane (CH4)-containing synthesis gas (3). The synthesis gas is subsequently fed to a fractionation device (Z) for separating off at least one hydrogen-rich fraction (7, 9) and one methane-rich fraction (10) and also a carbon monoxide product (6). The methane-rich fraction (10) separated off in the fractionation device (Z) is recirculated as feed (M feed) upstream of the conversion stage (DR).

摘要:
A distribution connection module (1) for telecommunications and data technology includes a housing (3) in which input and output contacts (4, 5) for the connection of cables or wires are arranged such that they are externally accessible. The housing (3) is designed with a cavity in which functional elements are arranged between the input and output contacts (4, 5).
摘要:
In a headrest (1) for a vehicle seat, having a carrier (5), at least one upper and lower linkage (11, 15) linked to the carrier (5), which can be pivoted around horizontal axles (7, 17), a impact element (13) linked to the linkages (11, 15) which forms at least one four-bar linkage (19) with the linkages (11, 15) and the carrier (5), and an energy storage device (25), the energy storage device (25) driving the four-bar linkage (19) in the event of a crash, so that the impact element (13) comes out forward from an original position into a crash position that is locked against a backward movement by a crash lock, the upper linkage (11) and the lower linkage (15) are unparallel with respect to one another.
摘要:
In a headrest (201) for a vehicle seat, having a support (205), at least one upper and lower linkage (211, 215) hinged to the support (205), which are pivotable around horizontal axles (207, 217), an impact element (213) hinged to the linkages (211, 215), which forms at least one four-bar linkage (219) with the linkages (211, 215) and the support (205), and an energy storage, the energy storage driving the four-bar linkage (219) in the event of a crash, so that the impact element (213) is driven out forwardly from an initial position into a crash position that is locked rearward by a crash lock, a drive (271) is provided by way of which, in normal use, the headrest (201) can be brought from its initial position to at least one other comfort position.
摘要:
A table can be folded in the interior of a motor vehicle and comprises a table top arranged on a vehicle-mounted support so that the table top can be moved from a resting position, in which the table plane is oriented substantially vertically, into a usage position oriented substantially horizontally. The support extends in the longitudinal direction of the vehicle and the table top is fastened to the support so the table top can be pivoted by a table top retainer from the vertical resting position into a horizontal position about a pivot axis in the longitudinal direction of the vehicle. The table top and/or the table top retainer can be locked in the usage position by a locking device when the table top is in the horizontal position and/or in the vertical position. When the table top is in the horizontal position and/or in the vertical position, the table top retainer is supported so that it can be moved in or opposite the direction of travel to lock the table top retainer into a catch recess of the support that extends in or opposite the direction of travel, and the retainer is secured against pivoting about the first pivot axis.
摘要:
A vehicle seat (1), in particular commercial vehicle seat, is provided with a framework, in particular scissors-type framework (3), a seat frame (10) which is articulated thereon via a pivot axis (B), and a backrest (20) which is attached to the seat frame (10) and by means of which a torque acts about the pivot axis (B) on the seat frame (10) in the event of a crash or misuse. The framework (3) has a first catch element (31) and the seat frame (10) has a second catch element (32) which normally do not interact. In the event of a crash or misuse, the catch elements approach each other and then interact creating a further path for the force flux.

A cable connector (1) for printed circuit boards includes a housing (2, 3) and at least two contact elements (4). Each contact element includes a contact (11) for connecting electrical wires and a fork contact (6, 7) for making contact with a printed circuit board. A surge arrester (17) is arranged within the housing (2, 3) and is arranged electrically between the contact elements (4).
摘要:
It is proposed a connection system for connecting a contact receptacle of a connector and a contact header of a counterpart connector. The connection system includes locking means for maintaining the contact receptacle in an intermediate position into a frame of the connector, and unlocking means for releasing the contact receptacle from its intermediate position.
