Title: Wind energy carousel with symmetric profiles which can be mutually adjusted
Inventor: MUELLER HANS
IPC: F03D3/06
Filed: 1981-10-17
Abstract: The wind energy carousel represents a specific development of the wind power machines with a vertical axis. Its predecessor is the VAWIAN, which operates with rigid vanes. In the Statusbericht- Windenergie (Progress Report - Wind Energy) (VDI-Verlag) it is said concerning this in paragraph 5 on page 282 that: "Further essential improvements in the output and in the reduction of peak forces are to be expected by controlled vane adjustment." Further advantages are that operation can take place in the working range with the highest ca value, and that it is also possible to increase the lift substantially with the aid of flaps, similar to the Fowler vane. Furthermore, two rectangular faces are utilised which are located at a mutual distance of such a size that they can be counted together. Conventional wind energy installations with a horizontal axis utilise only a circular face. That is to say  pi /4 D<2> to 2D<2>, and for D = 10 this corresponds to 200 to 78.

Title: Constructional element consisting of a hollow body which can be sealed air- and vapour-tight by walls and rigid or mobile sealing bodies
Inventor: BECKER OTTO ALFRED DR
IPC: E04C1/40
Filed: 1982-02-03
Abstract: Constructional element consisting of a hollow body which can be sealed air- and vapour-tight by walls and rigid or mobile sealing bodies, according to parent application P 3,200,246.7. The subject of the additional application is likewise means for causing substances to expand in the hollow body, whereby the constructional element is stressed and its bending strength is thus increased. The swelling agents and solvents suitable for this purpose can be of inorganic or organic nature. Preferably, they are dissolved in liquids which promote swelling, for example acetone, ethyl acetate or methyl alcohol. Especially substances forming gels which swell by absorption of solvents and solidify like a jelly are suitable for stressing. Water as a swelling agent is in this case partially bound chemically. Predetermined swelling of swelling cements, swelling mortars or the like is initiated by additives. Oxides such as CaO, SiO2, Al2O3 or Fe2O3 are added together with activators to the cements. Addition of water effects hydration and intracrystalline swelling of, for example, the calcium aluminate or hydrated calcium silicate effects an increase in volume.

Title: Device for blowing a fluidising medium into a fluidised bed
Inventor: BOBIK MICHAEL DR
IPC: F23C10/18
Filed: 1982-02-26
Abstract: For blowing the fluidising medium into a fluidised bed, it is proposed to group the nozzles together and to arrange them on pipes which are arranged individually or collectively so as to be height-adjustable relative to the fluidised bed and are sealed with respect to the floor of the fluidised bed. This device is suitable in particular for control of the combustion output of a fluidised fuel bed, the height of the fluidised fuel bed being controlled in correspondence with the heat output required, independently of the fuel input and/or the fluidising gas. Changing the height of the fluidised fuel bed also enables the immersion depth of any heating surfaces in the fluidised bed to be affected for output regulation of the steam generator. Furthermore, the design makes possible the superposed arrangement of a plurality of fluidised beds, such as, e.g., dryer, preheater and combustion bed, as used, for example, in the combustion of sewage sludge or refuse.
