This invention relates to a loading pallet. Conventional pallets of wood show deficiencies with respect to durability and service life. In order to eliminate these deficiencies and also other ones involved with conventional wood pallets, according to the present invention a pallet with a load-carrying platform of corrugated sheet metal is proposed, which platform (3) is supported at its opposed ed...

In a sludge thickener, supernatant fluid is drawn off via peripheral ducts and oxygenated at a suitable location. The supernatant fluid is thereafter reintroduced into the thickener via diffusers distributed transversely of the thickener and intermediate the peripheral ducts. The generation of nauseating smells is thereby prevented, and an advantageous increase of the concentration of the sludges ...

A device for supporting a moveable seat, for example a seat in a motor vehicle, by means of sliding rails which can be displaced in their longitudinal direction on roller facilities situated between the sliding rails and stationary alignment rails, the position of the seat being set by a mechanism which arrests the movement of the seat and involves, if desired, notches on at least one alignment ra...
