Patent DE-4039346-A1 (DE)
Inventor: MEZ GEORG
IPC: F16L23/00
Filed: 1990-12-10
Abstract: In the connection of rectangular air-conditioning channels, prefabricated flange connections are used. These consist of a frame (12) with four corner angles (63) and four frame legs. The frame (12) must hold together until it is pushed onto the channel end and is spot-fixed there. Previously, for the connection of corner angles (63) and frame legs, use was made of centre-punch presses or other presses. By means of the invention, it becomes possible to secure the corner angles (63) on the frame legs with a striking instrument. To this end, a bead (24) is bent into the frame legs, the walls (33, 34) of which are guided in an elongated slot (92) of the leg halves (94, 97) of the corner angle (63). With their front region (123, 124) they pass into a deformation space (122) where they are deformed so that corner angles (63) and frame legs (33, 34) no longer separate from one another. <IMAGE>

Title: Solar collector for heating water - comprises thin opaque foil stuck on fabric or felt and is heated by sun and indirectly heats felt and water being passed through
Inventor: COST KARLFRIED
IPC: F24S10/80
Filed: 1991-02-15
Abstract: The solar collector for heating fluid e.g. water has a thin heat absorbing opaque and water tight metal foil. The foil is laid on a second layer of fleece, fabric or felt, and this is indirectly heated through contact with the foil which is heated by the sun. There is almost no superficical pressure on the second layer which may be stuck to the foil with adhesive over the whole surface or only part of it. There is capillary attraction between the two layers which completely soaks the felt layer, the dry spots drawing moisture from the wet areas so that the obverse side of the foil is cooled by fluid or water. ADVANTAGE - The foil is very cheap as it requires no labour and the adhesive is also cheap saving in cost by comparison with other collectors.

Title: Supplying greenhouse with carbon di:oxide free from harmful cpds. - by aerobically growing microorganism using methane, in presence of oxygen, burning prod. and feeding to greenhouse
Inventor: SOYEZ KONRAD DR
IPC: A01G9/18
Filed: 1991-08-07
Abstract: In supplying greenhouses with CO2 free from harmful components, micro-organisms which use CH4 are cultured aerobically on natural gas contg. at least 15 vols.% of CH4, in presence of O2 at a ratio of CH4:O2 of 0.35-1.5:1.  Gaseous waste prod. is then burned, opt. after addn. of further O2 and/or CH4 and is fed to the greenhouse. Appts. pref. comprises a container holding a bioactive culture of aerobic, CH4-utilising microorganisms in a nutrient soln.. Connected to the container is combustion chamber(s) which are in turn connected to the greenhouse or to means for intermediate storage and/or conditioning.  A greenhouse with a surface of 3590 m2 needed a supply of CO2 at a rate of 10 g/square m/h.  72.5 cubic m/h of natural gas, free from S and Hg and contg. 40% CH4, and 197.5 m3/h of air were fed to a reactor contg. the microorganism ZIMET B 502, which was grown in a nutrient salt soln., at pH 5.7 and 38 deg.C for 6 h.  Prod. was 12 kg/h of biomass and 21.6 kg/h of CO2.  Waste gas contg. 6.06% O2, 3.91% CH4, 5.89% CO2 and 84.14% N2, was burned, giving a further 14.3 kg/h CO2.  Ratio of CH4 converted in the bioprocess: CH4 directly burned was 3:1. ADVANTAGE - Gas fed to the greenhouse is free from NOx and contains 0.003% CH4, compared with 0.01% after simple combustion of the natural gas.  As less heat is liberated, the CO2 can be fed to the greenhouse even during intense sunlight.  Process can use microorganisms, the cell substance of which can be used for fodder or for recovery of cell contents, e.g. water-sol. cpds. affecting plant physiology (e.g. raising yield). In an example, microorganism is pref. the bacterium ZIMET B 502. Natural gas free from Hg and S is used in amt. of 8-50 l/m2 of greenhouse surface.  Biological process is carried out so that the residual CH4 concn. in the waste gas is not above 3 vols.%..

Title: Tyres with rapid change in road grip - have tread which incorporates features with electro-viscous substances so that instantly applied voltage changes friction to road surface
Inventor: LIEBIG WILLI
IPC: B60C11/16
Filed: 1991-08-12
Abstract: Adjustable tyres can have their friction properties changed by applying special pressure agents to bores or chambers in the tread area. In the structure there are elastic bores or pressure-controlling lines filled with electroviscous substances; these can be converted from the liq. to the solid state by applying a voltage to them which also combines increases in their volume and pressure; the effect produced is to increase the dia. of the tread, to concentrate the absorbed forces on a smaller surface, and to split off films of ice or water. ADVANTAGE - The condition of the tread can be modified rapidly (to suit changed road conditions). The road grip can therefore be improved as required, whether the vehicle is moving or stationary.
