Patent DE-4101727-A1 (DE)
Title: Transparent PVC profile for swimming pool cover - has top covering layer of UV resistant transparent plastic
Inventor: HELGE HANS HEINZ
IPC: E06B9/17
Filed: 1991-01-22
Abstract: Transparent PVC profile bars for floating roller covers for swimming baths have a transparent PVC top side (2) on the remaining single-piece support part of the profile bar (1) of the same material, with a strongly bonded surfacing layer (6) of transparent plastic such as polymethylmethacrylate (PMMA) etc. which is stabilised against UV radiation to the same or a higher degree than the PVC of the support part. USE/ADVANTAGE - The profiles attach to each other to form a floating roller cover which is pulled over the swimming pool and collects the heat from the sun and transfers it to the water via the bottom side (3) of the profile which is pref. covered with a black coloured PVC layer (5) which transmits the heat to the water more efficiently. The construction allows the profiles to be constructed predominantly of PVC which is cheap and has good mechanical properties, while the outer layer (6) which is exposed directly to the sunlight is made of a different material which is less susceptible to degradation by direct sunlight than the PVC.

Patent DE-4232411-A1 (DE)
Inventor: LECHTENBOEHMER HANS
IPC: E05F15/635
Filed: 1992-09-28

Patent DE-4305072-A1 (DE)
Title: Processing metal-plastic cpd. sheeting
IPC: B29B17/02
Filed: 1993-02-19
Abstract: The method is for treatment of metal-plastic cpd. materials, e.g., aluminium-plastic cpd. sheeting. Deformation of the cpd. material and sepn. occurs by using the difference between the individual materials. The cpd. material is subjected to selective grinding, and prior to this process is broken into very small pieces with a dia. of less than 10mm.The grinding takes place in a micro vortex mill in the ultrasound range. The cpd. material is deformed by heating and/or cooling, e.g., in an extruder, and it is the metal constituents which are partic. deformed. Sepn. takes place by sieving or by flotation in a flowing bed. After dyring the metal and/or plastic constituents are made into briquets.
