Title: Wind energy converter for installation on garages, bungalows and all other flat roofs suitable therefor
Inventor: HUSNIK FRANZ
IPC: F03D3/00
Filed: 1988-10-31
Abstract: Wind energy converter for installation on garages, bungalows and other flat roofs for the purpose of obtaining electrical energy, comprising a bracket, the cruciform ends of which are fastened with pegs on the concrete surface. In the centre is an opening for a rotatable pin. Situated around the latter is the ball bearing slewing ring and above the slewing ring are three bearing blocks connected to one another, the central one representing the pin as a rotatable connection to the bracket. Located above the bearing blocks are three axle bearings in which the drive axle runs. Fastened on the axle are four hubs having eight spokes and four vanes, two on the left and two on the right which diagonally oppose each other, the vanes being laterally bounded by triangular end pieces. Fastened on the central bearing block is the wind indicator. Located on all three bearing blocks are mountings for a screen running obliquely, which serves to configure the lower semicircle in a useful manner. Located thereabove is a partition which serves to prevent the two different air currents mutually obstructing each other. Located at the end of the drive axle is a large toothed wheel which, via a pinion, operates a small generator for light winds, and, by means of its shaft passing through, automatically also connects the large generator via a centrifugal clutch in the event of strong wind force.

Abstract: Interferometer for measuring angular velocities in three-dimensional space with the aid of the phase shifts caused by the Sagnac effect in optical fibres and using three mutually independent interferometer arms which are assigned to the x, y and z axes in space. In order to obtain only a slightly enlarged overall volume by comparison with a single-axis fibre gyroscope, and to manage with only one signal processing unit, the three optical fibres (10, 11, 12) are arranged in a mutually orthogonal fashion on a spherical support member (13) and potted (encapsulated). The coupling-in points of the interferometer arms (10, 11, 12) are linked to one another via an optical 6-port gate (14) and is coupled to a light-transmitting and a light-receiving device (9 and 17, respectively). The optical waveguides (10, 11, 12) each have a mutual difference in wavelength which is greater than the limiting coherence length of the light emitted by the light-transmitting device (9). <IMAGE>

Title: Filling element
Inventor: AHLERS EGON ING GRAD
IPC: B67C3/10
Filed: 1989-03-22
Abstract: In the case of a filling element for filling machines for filling bottles, cans or similar vessels with a liquid, a probe, which controls a liquid-discharge valve of the filling element, has a portion at its end protruding over the lower side of the filling element and reaching into the vessel to be filled in each case, which portion comes into contact with the level of the liquid when a predetermined filling level has been reached, and, as a result, a signal which triggers the closing of the liquid-discharge valve is obtained. The probe comprises a light-guiding element, which has at least one light guide and at its one end, which is remote from the probe portion, is coupled up optically to a light-emitting element and to a light detector. At its other end, which forms the probe portion, this element is designed in such a manner that feedback of a light current, supplied to the probe portion, to the light detector takes place, which feedback is dependent on the optical density of the surrounding medium.

Title: Process and equipment for melting scrap iron and scrap steel
Inventor: SANTEN SVEN
IPC: C21B13/12
Filed: 1989-04-14
Abstract: In a process for melting scrap iron and scrap steel, scrap is fed through a shaft furnace in countercurrent to a reducing gas. The reducing gas is formed by air flowing through a plasma generator and coal and/or hydrocarbon being blown into the hot air in such a way that the (CO2 + H2O)/(CO2 + H2O + CO + H2) ratio of the resulting gas becomes smaller than 0.2. The energy required for melting is supplied as sensible heat of the reducing gas. The energy required for preheating the scrap is supplied by an oxygen-containing gas being introduced at a multiplicity of points along the flowpath of the reducing gas into the preheating zone, in particular for the stage-wise combustion of the reducing gas. The introduction of the oxygen-containing gas at the said multiplicity of points is adjusted to have the effect that the gas retains its reducing effect on the scrap metal at scrap temperatures above 1000@C and preferably even above 800@C. Furthermore, the invention comprises equipment for carrying out the process, the equipment consisting of devices which correspond to the various process features described above.
