Title: Water-power plant by means of cross-flow turbine, integrated rotary rake and retaining device
Inventor: SCHROETER HEINRICH
IPC: F03B13/08
Filed: 1987-12-02
Abstract: A water-power plant by means of cross-flow turbine, retaining device and integrated rotary rake which, as a module, form the energy-extraction device and, arranged individually or multiply next to one another and mounted in a framework structure, provide a sluice which, guided on both sides, can be raised and lowered in the raceway, is installed directly in flowing water, auxiliary units being arranged in a space safe against high water on the bank. A cross-flow turbine module consists, here, of an impeller with a horizontal axis, of fixedly connected rake rings and of a coaxially pivotable regulating flap which closes sealingly against stationary rake prongs. The power transmission from the impeller to the generator takes place via a chain drive and/or gearwheel mechanism. Alternatively, a ring generator directly flanged elastically to the impeller is used. The disposal of scum takes place via a bypass flap arranged at the top and by the time-stipulated raising of the sluice. The energy-extraction device designed as a movable sluice makes it possible, any time, to cancel the build-up generated by the water-power plant. The optimum blade curvature of the cross-flow turbine impeller is provided when the blades point towards the centre point on the inside of the annular grating, terminate tangentially on the outer circumference and describe an arc of a circle therebetween.

The second consists of five strip-shaped parallel main electrodes between which only one type of single electrodes is attached. The single electrodes form switching areas with the main electrodes, the light transparency of which can be electrically controlled. The single electrodes are connected to the drive electronics via bonded connections. The electrode structure with four main electrodes provides for triple multiplex operation and that with the five main electrodes provides for quadruple multiplex operation. <IMAGE>

Title: Sanitary control-disc valve
Inventor: HUBATSCH HORST
IPC: F16K47/02
Filed: 1989-01-26
Abstract: A sanitary control-disc valve contains in the customary manner, in a cartridge housing, a fixed control disc, relative to which a movable control disc resting upon it can be moved linearly. A braking device opposes the linear motion of the movable control disc, at least in the closing phase. It comprises a stepped bore with a region of larger diameter and a region of smaller diameter running through the movable control disc perpendicularly to the axis of the valve. Passing through this stepped bore is a pin which likewise has a region of larger diameter and a region of smaller diameter. The pin rests against the internal surface of the cartridge housing on both sides. The head of the pin interacts in the manner of a piston and cylinder with the region of larger diameter of the stepped bore, at least during part of the stroke of the movable control disc (Figure 2). <IMAGE>

Title: Pulsed anti-lock brake for motor vehicles, particularly for motor cycle combinations
Inventor: DEINLEIN-KALB HANS
IPC: B60T8/32
Filed: 1989-01-30
Abstract: The invention relates to a pulsed anti-lock brake which can be integrated into an existing brake system as a third brake unit. A piston pump driven by an electric motor is used directly or indirectly to supply pressure to the wheel brakes, the piston pump also coming into action as a brake booster and, at the same time, assuming the function of a load-dependent frequency modulator, irrespective of the vehicle speed. The control frequency of the pulsed pressure in the low to medium brake-pressure range is 9 to 7 hertz; in the case of full braking, the control frequency is set at about 5 hertz. During pulsed braking, the level of the pulsed brake pressure is controlled directly or indirectly by a pressure-regulating valve which is loaded by the brake pedal supplying, as it were, a reference input variable via a compression spring. <IMAGE>
