Patent DE-2411628-A1 (DE)
Title: Rigid building panels faced with mineral filled polyester - with resin impregnated paper pulp core
Inventor: REISCHUCK MANFRED
IPC: B29C70/00
Filed: 1974-03-12
Abstract: Facia panels for building, esp. rear ventilated facade panels with a stepped groove running round the sides, and comprising a flat, self supporting and cured carrier sheet of suitable size coated on both sides with a covering layer contg. a high proportion of mineral filler and optionally a decorative application on the facing side, are made by (1) applying a 0.4-0.8 mm, esp. 0.5-0.7 mm thick layer of a flowable thermosetting compsn. contg. 60-70% mineral filler, pigments and thickening agents, to a release sheet of paper or foil, (2) lining the layer with a 1.5-2 mm thick sheet of unrefined paper pulp impregnated with an incompletely cured thermo setting resin, opt. using an intermediate layer of a very thin glass fibre fleece, (3) storing the resulting laminate with the release layer downwards for several hours, (4) laying up two equal-sized pieces of the laminate with the pulp sides together and biaxial displacement to form a stepped edge round the sheet, and (5) curing the sheet by heating under light pressure. The panels are lightweight and cheap due to the absence of large amounts of glass fibre reinforcements as is used with known GRP panels. The mineral content of the facing can be varied (e.g. marble chips, etc.) to match existing buildings, e.g. in renovation work.

Title: Stagnant water oxygen enrichment - by planar electrodes suspended from float and connected to power supply
Inventor: BERGAUER HELMUT DIPL ING
IPC: C02F1/467
Filed: 1974-04-20
Abstract: Stagnant water in lakes etc. can be aerated with oxygen by perforated planar electrodes, suspended from a float to lie horizontal near the bottom of the water. The electrodes are connected to an a.c. source so that the water is dissociated into oxygen which becomes dissolved in the water, and hydrogen which rises in fine distribution and disappears in the atmosphere. this system requires little capital outlay and is easily installed. Oxygen can be introduced even into deeper regions of surface water with little expenditure of energy.

Title: Colour indexable spinning cop or wound bobbin - changes colour due to irradiation, for relating quality or yarn weight
Inventor: HOFMANN GUENTER
IPC: B65H67/06

Title: Bag filter for air or gas - with automatic on-stream cleaning
Inventor: WOLF WILHELM
IPC: B01D46/00
Filed: 1974-09-09
Abstract: A filter for air or gas has filter bags in at least one dust chamber, an inlet passage connected to the dust chamber, and an outlet passage for the clean air or gas, which passage is sepd. from the dust chamber by a wall in which the support tubes for the filter bags are secured. The air or gas flows from outside to inside the bags which are stretched over supports and a device is provided for cleaning the bags. According to the claim, the filter bags stand (rather than hang) in the dust chamber through which the air or gas flows downwards. The bag supports are designed to be used as the means of cleaning the bags. During cleaning of the bags, the dust dislodged from their surfaces flows in the same direction as the dirty air. It is not necessary to provide headroom for removal of the bag supports for changing the bags, and the filter plant is consequently small.
