Abstract: An installation device and an installation assembly including at least one installation device are disclosed, which can be used in conjunction with various connection technologies and also be incorporated in different wiring systems. One connection side of the installation device is provided with a contact element, which is compatible with both a mating contact element of a connection device that can be positioned on the connection side and an additional mating contact element of an additional connection device that can be located on the connection side, but differs from the first connection device.

Abstract: A method for injection molding a material consisting of a suspension of particles. The suspension of particles moves through convergent passages in an obturator and an injection channel so that the particles remain in suspension. The press has a head in which a portion of the feed channel and a portion of the injection channel, when the channel is open, is formed by a passage in an externally controlled obturator, the controlled obturator for the feed channel and the one for the injection channel being one and the same or adjacent, and disposed close to the injection orifice.
