Title: Device for reducing air humidity
Inventor: GUELDENPFENNIG WOLFGANG DIPL I
IPC: F24F3/14
Filed: 1982-09-16
Abstract: The device serves to remove part of the air humidity of a living space. The air humidity is precipitated on a cold wall of a refrigerator or of a freezer. To reduce the heat transfer on the cold wall, there are in front of this in the direction of the living space heat-insulating air spaces which have only a very low diffusion resistance to water vapour. These air spaces are covered by a thin foil on the side of the living space. The foil and the spaces are protected from damage by a mechanically very strong perforated plate or a grate.
Patent DE-3239929-A1 (DE)
Inventor: WESSMAN BOERJE
IPC: B63C9/135
Filed: 1982-10-28
Abstract: Bathing and swimming aid device particularly appropriate to small children. The device comprises a carrier ring (19) intended to be placed around the chest and two brachial cushions (17, 18) connected to the carrier ring (19). The size of the latter is such that it exerts an upward thrust sufficient for swimming. The brachial cushions (17, 18) are not or little immersed when in swimming position. They are essentially used for lateral compensation in case of swinging or pendular motion. The brachial cushions (17, 18) are arranged on top and at a distance from the upper portion of the arms (34, 35). They are attached to the upper portion of the arms (34, 35) and to the carrier ring (19) by means of holding straps (26, 27). The carrier ring (19) has a slot at its rear part so as to be adapted to different chest sizes; it is held by an annular tensioning strap. Said tensioning strap (30) and the holding straps (26, 27) form a harness wherein the brachial cushions (17, 18), the carrier ring (19) and the child (33) are held. Owing to the connection of the carrier ring (19) to the brachial cushions (17, 18), neither the carrier ring (19) nor the brachial cushions (17, 18) may be detached from the child carrying them. In the water, the child who carries the device takes automatically a vertical position which is felt as a normal position, so that the child is less frightened thereby encouraging the children to bathe and play in the water.

Title: Method of processing plant products from agriculture and forestry
Inventor: SCHRAUFSTETTER WILFRIED
IPC: A23K10/12
Filed: 1983-03-11
Abstract: A method for processing plant products from agriculture and forestry is described, which is self-sufficient from the energy point of view and by means of which not only alcohol can be produced but also non-perishable foodstuffs such as animal feeds, biological fertilisers and protein for animals and humans can be produced. This method essentially consists in pressing the products, during which process the cell structure is destroyed completely and the products are disintegrated completely, forming a solid and a liquid phase, and heating the liquid phase to an increased temperature by means of the pressing process and afterheating the products to the mashing heat by means of the exhaust gases of an internal combustion engine which drives the press. The internal combustion engine is driven by biogas produced in a biogas reactor. The liquid phase is fed to an alcohol distillery. The distiller's wash formed in this process is fed to a biogas reactor. After fouling has ended, the substrate from the biogas reactor is separated into protein, animal feed and biological fertiliser by means of a separating process. A generator for generating electrical energy is driven by an internal combustion engine running on biogas. <IMAGE>

Title: Transformer having an iron core which is composed of sheet-metal laminates
Inventor: ROTTHOWE HEINZ
IPC: H01F27/26
Filed: 1983-07-02
Abstract: In transformers having an iron core 1 which is composed of sheet-metal laminates, there is a danger of the limbs 2, 3 vibrating when the mains current is switched on, because of manufacturing tolerances, and of this leading to vibration noise. In order to prevent this, the yoke 4 which rests against the ends of the limbs 2, 3 is provided with conical projections 5 which are pressed into the limbs 2, 3 of the iron core. The conical projections 5, or corresponding prongs, brace the individual sheet-metal laminates of the relevant limb 2 or 3 respectively by pressing in, so that vibrations are prevented. <IMAGE>
Patent DE-3324160-A1 (DE)
Title: Rotary stretcher
Inventor: SCHEEK BERNHARD
IPC: F16C33/78
Filed: 1983-07-05
Abstract: The tubular portions arranged on a bent axle are supported on the axle via rolling bearings. The grease chamber of the rolling bearing is sealed to the outside by means of Nilos rings or the like. Arranged between the Nilos rings and the rolling bearing is a receiving ring which is connected to the Nilos ring in an oil-tight manner. One or more O-rings inserted into the receiving ring with prestress are arranged for sealing between the receiving ring and the rolling bearing. The receiving ring has a conically extending inner face, the larger diameter of which is directed towards the rolling bearing. As a result of the construction according to the invention, owing to the enlargement of the grease chamber, the operating life is considerably increased in the case of rotary stretchers having a grease chamber of the rolling bearing which is not readily accessible and also in the case of all designs in which the bearings are not readily accessible after assembly.
Patent DE-3328491-A1 (DE)
Title: Exhaust-gas gate to provide the possibility of separating an exhaust-gas catalyser from the path of the exhaust gases from an internal combustion engine
Inventor: WILD WOLFGANG
IPC: F01N3/20
Filed: 1983-08-06
Abstract: Exhaust-gas catalysers serve to clean the exhaust gases and thus protect the environment, but are damaged by exhaust gases which contain lead. However, unleaded fuels are not always available. In order to be able to continue to operate the engines on fuels with the potential to cause damage, without damaging the catalyser, the catalyser must be taken out of the path of the exhaust gases. This is accomplished by means of a gate which, depending on its setting, either guides all the exhaust gases into the catalyser or guides all the gases into a pipe which bypasses the catalyser. This gate guides all the exhaust gases to the catalyser (after being set appropriately) by blocking the gate outlet leading to the pipe which bypasses the catalyst and visa versa. This will be of use especially with engines of motor vehicles since, as means of transport, these are the most likely to require frequent conversion depending on the type of fuel available.

Title: Process for producing corrugated boards
Inventor: HUEBNER JOCHEN E DIPL KFM
IPC: B28B1/52
Filed: 1983-08-16
Abstract: A process for producing corrugated boards from lignocellulose and/or cellulose-containing particles treated in particular with cement or gypsum is described. In the process the particles forming a non-woven fabric are applied onto a continuous succession of individual substrates with suitable wave profile, then the non-woven fabric is separated into non-woven fabric sections in the region of the joints or in the overlapping region of the substrates. The substrates covered with non-woven fabric are subsequently pulled apart and then stacked to form packets of a certain size, compressed in a press to the respective final thickness and at the same time kept in the closed packet. After the opening of the packets the corrugated boards formed from the non-woven fabric sections are separated from the substrates and the substrates fed back into the production sequence.
Patent DE-3330961-A1 (DE)
Inventor: DIVISEK JIRI DR
IPC: C25B11/00
Filed: 1983-08-27
Abstract: A process for the manufacture of thin activated electrodes including a base metal, which can be iron, cobalt or nickel, with a good adhering active surface layer. Both the base metal and the surface layer are galvanically sequentially deposited as separate layers on a removable electrically-conductive carrier. The surface layer is deposited as an activatable alloy including the base metal and a leachable metal, particularly zinc. The galvanizing deposited layers are subsequently separated as a unit from the carrier. The alloy is activated by leaching the leachable metal therefrom before, during or after separation of the carrier. Two activatable layers of alloy can be deposited on the carrier with a layer of the base metal deposited between the alloy layers.
