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.

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:
The invention relates to a terminal block (1) for telecommunications and data systems, comprising a housing, in which first and second contacts (10, 12) for connecting leads are arranged, the first contacts (10) being accessible from the upper side (13) of the housing and the second contacts (12) being accessible from the lower side (14) of the housing, each first and second contact forming a contact pair. Each of said contact pairs has at least one interface, which is accessible from the exterior and is used to connect plugs or magazines, said interface being designed as a bifurcated contact (15) and the first contact (10), second contact (12) and the bifurcated contact (15) forming a one-piece contact element (18). The invention also relates to an associated contact element (18).
摘要:
A connection module that mounts to a frame includes a housing and electrical contacts positioned on different ends of the housing. A first fixing member defines a channel sized to receive at least a portion of a frame. A second fixing member is moveable relative to the first fixing member to extend at least partially across the channel of the first fixing member.
摘要:
The invention relates to an insulation displacement plug-in connector for telecommunications and data technology, comprising a housing (45) and a number of contact elements (43), wherein the contact elements (43) each comprise an insulation displacement contact (54) for connecting cores and a pin contact (53) for making contact with a printed circuit board, wherein at least one extension (55) is arranged between the insulation displacement contact (54) and the pin contact (53).
摘要:
A connecting module includes a housing, electric contacts for connecting wires and/or cables, and at least one fastening element that allows the connecting module to be fixed to an assembly frame. The fastening element is embodied at least in two parts, encompassing a first fastening piece and a second fastening piece. The connecting module can be put on the assembly frame by means of the first fastening piece and can be locked on the assembly frame with the aid of the second fastening piece.
摘要:
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 housing. The second contacts are embodied as at least one RJ45 plug-in connector.
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.
