Patent HU-203178-B (HU)
Title: Switching system and method for switching digital signals converted into symbol sequences provided with a head of path information content
Inventor: DEBUYSSHER PIERRE LEON
IPC: H04L/
Filed: 1987-01-20
Abstract: A switching system using an asynchronous packet switching technique. The packets may contain voice, data or video signals. The switching speed is increased owing to the processor (SPC) analyzing only some special packets and that it is located out of the transmission path of the packets. It may thus process these special packets at a lower speed than the transmission speed. This system also includes a header correction circuit (HC) which improves the quality of the transmission.

Abstract: Extrusion of a mixture of vegetable bits with a binder, particularly wood chips with a weather-resistant binder, involves precompressing in a compression chamber of an extrusion press the mixture by a compression stroke transverse to the extrusion axis, the compression stroke being delivered by at least one precompression piston. Prior to the precompression elongated bits of the mixture are acted on by an orienting influence so that the elongated bits are deposited substantially parallel to the extrusion axis. The outer layers of the mixture are compressed with a reduced precompression ratio so that the bits oriented prior to precompression remain fixed in position during the subsequent extrusion stroke. Preferably the elongated bits in the mixture are oriented by free fall of the mixture through a plurality of upright, thin-walled bars of approximately equal height positioned above the compression chamber during filling of the extrusion apparatus by a mechanical hopper moving to and fro over the bars continuously.
