Title: Wind driven power generator - has vertical tube over turbine wheel to increase air flow by natural draught effect
Inventor: RENDIGS ALFRED
IPC: F03D1/04
Filed: 1979-10-11
Abstract: A vertical tube is mounted on bearings so that it can be rotated about a vertical axis. An air turbine with a vertical axis is fixed at the bottom of the tube and coupled directly to a generator. The tube has air inlets on one side below the turbine. It tapers with a reducing cross section upwards and has adjustable outlet flaps towards the top. The tube produces a natural draught effect which increases the wind flow over the turbine. The air flow is adjusted by the outlet flaps and the tube is rotated to bring the inlets into the wind.

Title: Advanced leak detection esp. for reactor primary circuit - by numerous atmospheric samples all analysed at remote centre
Inventor: HAEGEN PROF DIPL-CHEM DR HANS
IPC: F17D5/02
Filed: 1979-10-31
Abstract: A method of sensitive, highly located and prompt measurement of liquid or gas leaks from closed plants, esp vessels and pipes in the nuclear and chemical industries, more specifically reactor primary circuits, consists of sampling numerous regions, and carrying out the collection, analysts and processing of the samples at a central, remote location. The location is chosen to eliminate ambient influences from radiation, temperature, humidity etc from the instrumentation. Specifically, tubes or small pipes are used for taking specimens from the ambient atmosphere in the region of pipes, ducts, etc., the samples being continuously extracted and fed to the analysis equipment. The method enables accurate determination of "leakage before rupture" to be achieved. Rapid results are obtd. The results can be quantified and qualified.

Title: Conical wheel gear transmission for automotive gearbox - has high and low positions of belt or chain discs related mathematically
Inventor: ABBOTT RANDLE LESLIE
IPC: F16H37/08
Filed: 1979-12-04
Abstract: The automotive gear has a steplessly adjustable cone disc encompassing gear, with a pulley belt or chain as transmission component. The diameters of the discs over which the transmission passes determine the variation in gear ratio and are alterable. The transmission position of the cone wheel gear is controllable from a high to a low position, and a reduction gear is fitted between gear input and planet gear carrier. To the reduction gear is connected a first coupling enabling coupling and uncoupling with the planet carrier. A second coupling is fitted between two parts of the planet gear, and the couplings are controllable so that both are disengaged, or that when one is engaged the other is not.

Title: Wind energy converter with deflector - has rotary cylinder on stationary axis, for wind flow to horizontal energy converter
Inventor: KOENIG FELIX VON
IPC: F03D1/04
Filed: 1980-06-09
Abstract: The converter provides an aerodynamic wind deflection for power generation, using a horizontal wind driven turbine. The system is partic. for integrating several wind driven power plants in buildings of any type. A rotary cylinder on a stationary axis is mounted in the wind flow direction and directs this flow in a desired direction, e.g. to the horizontal wind power converter. The rotary cylinder acts as a king pin and it makes the following wind turbine independent of the direction of the wind and its velocity by its deflective action. The deflecting cylinder may be also mounted behind the turbine, in order to deflect the downstream wind flow. In this manner the wind turbine can be operated under any wind conditions. The converter can be used in conjunction with a sleeve nozzle, using two or several blades.

Title: Dietetic composition with a laxative action and process for its production
Inventor: LEUSCHNER HARTMUT A
IPC: A23L33/105
Filed: 1981-03-18
Abstract: A dietetic composition which has a laxative action and consists of a combination of linseeds and lactose product and whose particles are completely coated with a layer of the lactose product has the result that the dosage in the dietetic composition in respect of the required amounts of linseeds and lactose is ready for use, i.e. is in the correct composition in terms of amounts. Furthermore, the linseed particles and thus breaks therein are covered with the lactose layer so that both the evaporation of volatile oils and the entry of atmospheric oxygen to the oils are prevented and thus the linseed is preserved in the fresh state.

Title: Spraying box
Inventor: DIXON GEORGE
IPC: B05B14/46
Filed: 1981-08-06
Abstract: A spraying box which can be used in particular in a paint spray device is provided. In said spraying box, the air contaminated with spray agent particles or droplets is sucked from a spraying region into a scrubbing chamber (13), at high velocity, over a free surface (15) of a liquid scrubbing agent in a tank (11). The air entrains liquid scrubbing agent. In the scrubbing chamber (13), the sprayed particles or droplets are scrubbed out of the air stream by entrained scrubbing agent, and the scrubbed air then emerges from the spraying box. The scrubbing agent containing the contaminant passes back into the tank (11), where the contaminants are deposited in the form of a slurry. The upper part of the scrubbing agent tank (11) is open over essentially the entire width and essentially the entire depth of the spraying box, scrubbing agent passing through the scrubbing chamber (13) together with the air stream falling back directly into the open upper part of the scrubbing agent tank (11). <IMAGE>
