A seat backrest is provided, comprising a framework () including an upper portion (), a lower portion (), a central support portion () and two side portions () formed integrally by injection molding a thermoplastic material; and an elongated reinforcement () embedded in the side portion () and the central support portion () by overmolding and extending along the side portion (), the reinforcement () being configured to bend along a boundary () between the side portion () and the central support portion (). A seat including the backrest is also provided.

Seat backrest and seat including the same

The invention discloses a seat pan (), being formed from a first thermoplastic composite material into a one-piece pan, the seat pan () having a weight loading portion (), wherein at least one slot () is provided in the area of the weight loading portion () of the seat pan (), and covering strips () are formed by overmolding on the side edges of straps () separated by the slot () and extending along at least a portion of the circumference of the slot () so as to reinforce the straps (), the covering strips () being made of a second thermoplastic composite material. Furthermore, the invention discloses a seat () comprising the above seat pan ().

The invention relates to a process for preparing isocyanates by reacting the corresponding amines with phosgene in the liquid phase, if appropriate in the presence of at least one inert medium, in which the amine and the phosgene are first mixed in a mixing chamber () to give a reaction mixture and the reaction mixture is fed to a reactor, the amine being added through an orifice () arranged coaxially to the mixing chamber () and the phosgene being added through feed orifices () in at least two planes () arranged at right angles to the axis () of the mixing chamber (), or the phosgene being added through the orifice () arranged coaxially to the mixing chamber and the amine through the feed orifices () in at least two planes () arranged at right angles to the axis () of the mixing chamber (). At least one plane () is arranged upstream and at least one plane () downstream of the orifice () arranged coaxially to the mixing chamber () in main flow direction of the reaction mixture. The mean residence time of the reaction mixture in the mixing chamber () is not more than 20 ms.

Process for preparing aromatic isocyanates

The present invention relates to a process for preparing isocyanates and an apparatus suitable for this purpose, and also its use. In the process, an amine and phosgene, both in the gas phase, react in the presence of an inert medium. A number, n, of amine streams are reacted with a number, n +1, of phosgene streams in a reactor. The number n is a positive integer of at least 1. All amine and phosgene streams are introduced into the reactor through annular gaps for mixing.

Method for producing isocyanates

The apparatus for the continuous catalytic removal of binder from metallic and/or ceramic shaped bodies produced by powder injection molding, which comprises a binder removal furnace through which the shaped bodies pass in a transport direction and are brought to a suitable process temperature, a feed facility for introduction of a process gas which is required for binder removal and comprises a reactant, at least one facility for the introduction of a protective gas into a reaction space of the binder removal furnace and a flare to burn the gaseous reaction products obtained in binder removal, wherein one or more devices which lead to a flow of the process gas directed transversely to the transport direction in the apparatus are present.

Device and method for continuously and catalytically removing binder, with improved flow conditions

A process for preparing acrolein or acrylic acid or a mixture thereof from propane, in which propane is dehydrogenated under heterogeneous catalysis in a reaction zone A and the propylene formed is partially oxidized heterogeneously in a reaction zone, reaction zone A being operated in loop mode and reaction gas mixture input stream A fed to the reaction zone A comprising added molecular hydrogen which is added to this input stream as late as possible.
