Patent DE-3924626-A1 (DE)
Inventor: MALLEK HEINZ
IPC: C10J3/22
Filed: 1989-07-26
Abstract: A gasification shaft in the reactor collects a loose heap of solid waste matter on a support at the bottom of the shaft in the form of a triangular hollow prism having longitudinal edges leaving gaps between it and the walls of the shaft. The support can be swung about its axis to open the gaps wider and shake the solid material. Oxygen containing gas is supplied at the top of the shaft and supports partial combustion of the solid material. Gas and partly burned solid material pass down through the variable gaps into a combination chamber below the shaft into which more oxygen containing gas is fed both from above through the prismatic support and from below through an ash chamber at the bottom of the combustion chamber after passing through lower gaps between an emptying device of triangular prism shape, below which is an ash removal chamber. The additional oxygen supplied from below into the combustion chamber assures the complete combustion of the solid material so that treatment of the ash outside of the reactor becomes unnecessary.

Title: Spiral winding of tube or similar cylinders - in which rectangular thermoplastic strip is spirally wound along mandrel with high overlap which causes inclination
Inventor: HAWERKAMP MANFRED
IPC: B29C53/58
Filed: 1989-11-22
Abstract: In the prodn. of thick walled cylindrical tube,  thermoplastics strip from an extruder is spirally wound onto a mandrel. The rectangular section strip is initially wound flat onto the mandrel and then by almost completely overlapping  successive windings a wall thickness is built up with the wound strip at an angle to the mandrel surface. Wall thickness depends on the angle of inclination of  the strip which is related to the forward movementm of the extruder along the mandrel. Initial and final wound sections of the tube are removed to produce a uniform thickness stress free tube. USE/ADVANTAGE - Produces cylindrical components or tubes by spiral winding which eliminates temp. differences in the  overlapping areas during winding, giving a stress free tube without shrinkage or deformation.

Abstract: The common plant is for breaking down plastics, steel plate or cardboard cartons. It is fitted directly on the face wall (2) of a rotary tube furnace, and incorporates delivery paths and safety features for the broken-down material. The chamber (3) in which the breaking down process takes place is connected to the rotary tube furnace combustion chamber, and degassed products, by reason of the vacuum appertaining in the furnace, are conducted away into the furnace on a controlled basis via a puppet valve. Through the even open connection to the combustion chamber, a pressure build-up in the breaking-down chamber (e) is not possible. This chamber is absolutely gas-tight in its sepn. from the waste input equipment during the breaking-down process. The break-down chamber can be very small, and the oxygen available in it is low in quantity, leading to no uncontrollable fire or explosions. USE/ADVANTAGE - For the break-down and combustion of special refuse, e.g. plastics, steel plate or cardboard cartons, with the considerable redn. of gas-form intermediate products.
