Abstract: An apparatus for treating waste material, particularly organic catering waste, includes a hopper having an outlet at a bottom part thereof; a comminuting device adjoining the hopper for receiving waste material from the hopper; a chamber having an upper portion and a lower portion; and a raising device having an inlet and an outlet. The outlet of the raising device opens into the hopper above the hopper outlet and into the upper portion of the chamber, whereby waste material lifted by the raising device is discharged in part into the hopper and in part into the upper portion of the chamber. The apparatus further has a supply device situated below an outlet of the comminuting device and in the lower portion of the chamber. The supply device advances waste material from an outlet of the comminuting device and from the lower portion of the chamber to the inlet of the raising device.

Abstract: The seat consists essentially of a seat frame and a back rest frame, which are screwed to each other by way of plates which are welded thereto. The seat frame and back rest frame each consist of a curved sectional member, whereof the ends are constructed as skid-type feet. The seat frame and back rest frame are each strengthened by a transverse reinforcement and, when the surface of the seat or back rest includes a lattice, is welded to the frame, when the surface of the seat or back rest includes a plastic shell, it is attached to the frame by clamping.
