Abstract: The invention relates to a method for producing an installation for implementing a method for cryogenic air separation, whereby at least one constituent of the air used is obtained as a product by means of a selected method variant. Said installation comprises at least one coldbox in which a module is arranged. The invention is characterized in that several classes are predefined, each class determining the dimensions of the coldbox pertaining thereto, and the coldbox of each class being large enough to hold the module for at least two different product quantity requirements and/or at least two different method variants. A coldbox of a certain class is selected and the module is arranged in the coldbox of said selected class.

Abstract: The invention relates to a low temperature air fractionation system comprising several modules consisting of at least one heat exchange unit, a pressure column and a low pressure column, in addition to the accessories belonging to the respective modules and at least two cold-boxes, wherein the module and/or the accessories are arranged. The invention is characterized in that at least one of the cold-boxes is embodied in the form of a main box and at least one of the cold-boxes is embodied in the form of a secondary box. The secondary box contains at least one module and the accessories of the module disposed in the secondary box are mainly located in the main box.

Abstract: A system and method for data element extraction from hierarchically structured documents. According to one embodiment, a generator extracts a plurality of data elements from a stored hierarchical data file that is in a first format, in accordance with a data set that is unique to the particular hierarchical data file, and arranges the plurality of data elements in a second format so that the arrangement provides the plurality of data elements with a document context, and so that the data elements can be further arranged in a third format without using the data set.

Abstract: A device for non-contact support of a continuous moving web of material employs an air clamp stabilizer that includes a Coanda slot and a backstep that is located downstream of the direction of the airflow extending from the Coanda slot. This configuration permits a Coanda jet to expand and to create an additional suction force. Vortex formation may also occur which further contributes to the strength of the suction force. As the web passes the stabilizer, an area of the web material rides on an air bearing that is maintained above the stabilizer surface and downstream of the backstep.

Abstract: The invention relates to a method for producing a plate heat exchanger from a plurality of heat exchanger blocks (1a, 1b). Each heat exchanger block (1a, 1b) has mounted on it a header (6a, 7a, 6b, 7b) which extends over at least part of one side of the heat exchanger block (1a, 1b). The heat exchanger blocks (1a, 1b) are arranged next to one another, and the headers (6a, 6b; 7a, 7b) of two adjacent heat exchanger blocks (1a, 1b) are provided on their mutually confronting sides with orifices and are connected to one another in such a way that a flow connection occurs between the two headers (6a, 6b; 7a, 7b).

Abstract: The invention relates to an adsorber station with a first adsorber (A) and a second adsorber (B). A first closed loop pipeline (1) is connected to the adsorbers (A, B) and is provided with product gas feed line valves (4A, 4B) and regeneration gas discharge line valves (6A, 6B). A second closed loop pipeline (2) that is connected to the adsorbers (A, B) has product gas discharge line valves (7A, 7B) and regeneration gas feed line valves (8A, 8B).

Abstract: The invention relates to a plate heat exchanger with a heat exchanger block which has a multiplicity of heat exchange passages. The heat exchanger block has mounted on it a header which extends over at least part of one side of the heat exchanger block and makes a flow connection between part of the heat exchange passages. The header is provided with a fluid connection which is arranged essentially perpendicularly to that side of the heat exchanger block over which the header extends.

Abstract: A device for receiving a gas discharge lamp of an automotive headlight has a housing (1) in which an igniting apparatus is arranged. This housing (1) also has an insertion opening (2) with recesses (4) at an edge in an outer wall (3) of the housing for receiving a lamp base with radially projecting bayonet lugs (18) on the base, said lugs axially securing the lamp base (17) in the insertion opening (2) when the lamp base is turned into a locked rotational position. A box (9) is also provided on the housing (1) for a feeder plug (11) which provides an electric power supply. With such a device having an integrated igniting apparatus, mechanical locking is provided for the box arranged on the housing to prevent insertion of the feeder plug as long as a bayonet connection of a base of gas discharge lamp is not in the locked rotational position.
