Patent DE-3941742-A1 (DE)
Inventor: WELTER HUBERT DIPL ING
IPC: B29B17/02
Filed: 1989-12-18
Abstract: The invention relates to a method and plant for the disposal of partialy dismantled refrigerators, especially for the disposal of chlorofluorocarbon-containing polyurethane foam. 
<??>The partly dismantled refrigerators are introduced into a disposal plant which can be sealed gas-tight, can be operated under a vacuum and can be evacuated at a number of points, and comminuted in a comminution plant. The materials adhering to the PUR foam are mechanically separated off. The residue-free PUR foam is ground to a powder, the cells of the PUR foam being destroyed and the bound chlorofluorocarbon-containing blowing gas being released. 
<??>The residues and PUR powder are collected separately, and the chlorofluorocarbon-containing gas obtained on comminution and grinding is liquefied. 
<??>The advantages achieved by the invention are especially that the disposal of the refrigerators supplied is complete, more than 99% of the chlorofluorocarbon-containing gas being liquefied and recycled together with the other recovered materials.

Patent DE-4029671-A1 (DE)
Inventor: LEY HANS
IPC: B23F19/10
Filed: 1990-09-19
Abstract: At present, workpieces with a basically circular shape with tooth-like projections, e.g. gearwheels, can only be manufactured using hob-milling or hob-cutting techniques requiring expensive tools. By superimposing at least two circular motions, a workpiece can be controlled to follow a cycloidal trajectory so that, for the zone of engagement with the rotating workpiece, virtually any desired variation in cutting line, even a straight line, can be set. This makes it possible to work with simply shaped tools and high-tensile tools materials, as is the case with normal lathe work.

IPC: B32B17/12
Filed: 1990-10-19
Abstract: The invention relates to a panel or shell-like structural component which can be subjected to high static and dynamic loads. The component consists of a reaction plastic like polyurethane and a reinforcement embedded therein with the structure: - a first and a second outer layer (10, 18) of an elastically extensible organic fibre fabric; - a first and a second stiffening glass fibre layer on the inner surface of the first and second outer layers (10, 18); and - a compressible spacer layer of polyamide fibres inside between the two glass fibre layers (12, 16). The reinforcing structure is porous enough in the region of all the layers so that it can be impregnated with a low-viscosity reaction mixture formed on the foaming of the reaction plastic.
