Title: Control device for small hydro-electric power systems
Inventor: OSSBERGER KARL-FRIEDRICH DR
IPC: F03B15/02
Filed: 1983-09-09
Abstract: A control device is described for a small hydro-electric power system, especially a flow turbine, for operation in the case of a power station having a synchronous generator which can be changed over between independent operation and network operation. In independent operation, the control device operates using speed regulation. When a changeover is made to network operation, the use of speed as the control variable is dispensed with and the control device operates using water-level or volume-flow control. This is made possible in that the speed of the synchronous generator and of the water turbine is kept constant by the network if the network power is virtually infinitely large in comparison with the turbine power. <IMAGE>

Title: Displaceable stop on sawing machines, in particular crosscut saws with integrated electronic measurement of the displacement path or of the workpiece length and automatic adjustment
Inventor: GRESSER GERMAN
IPC: G01B5/02
Filed: 1983-09-13
Abstract: The application relates to a device for measuring bar-shaped workpieces on so-called crosscut saws. On these crosscut saws, the workpieces must be cut to a (variable) given defined length dimension. In order to define a desired workpiece length, use can in principle be made of an inch-rule, a mechanical measuring device or electronics. The present application combines a known electronic measuring device and its associated transducer (e.g. incremental rotary transducer) with a constructionally matched displaceable stop. The electronic digital display constantly indicates at the same time the variable spacing between cutting disc and the displaceable stop. The workpiece length then corresponds exactly to this spacing which is equal to the desired dimension.

Title: Arrangement for adapting a wind wheel to an electric generator
Inventor: SCHOENBALL WALTER
IPC: F03D9/12
Filed: 1983-09-17
Abstract: A perpendicular worm shaft is rotated by the wind wheel in the direction of the rising worm convolution. On account of its gravitational force, a flywheel slides down on the worm shaft in a rotary manner in the direction of the descending worm convolution. The downwards movement of the flywheel is maintained as long as a corresponding rotary movement of the worm shaft driven by the wind wheel does not cause the flywheel to reach the lower limit of the worm shaft. Located at the outer margin of the flywheel is an electric generator which is driven by means of a friction wheel or in another manner by the flywheel. The height of the worm shaft is of use to the flywheel as a short-time energy accumulator. Attached below the flywheel is a vertically adjustable support with which the effective mass of the flywheel can be influenced in order to also control a uniform speed of the flywheel even at a non-uniform load of the electric generator. In addition, a device is attached to the flywheel in order to stop the wind wheel.

Title: Control device for a heating plant
Inventor: ALBRECHT ROBERT
IPC: G05D23/24
Filed: 1984-02-07
Abstract: The firing takes place in dependence on the external temperature and the feed temperature or return temperature, according to a set heating curve which is specific to the plant. A correction value can be set at an adjusting member for a desired alteration of the room temperature. In order to make the alteration of the room temperature largely independent of the heating curve set and of the external temperature, a correction value of the adjusting member and a temperature signal dependent on the feed temperature are processed in an adaptive circuit. With a positive correction value and a low feed or return temperature, the heating curve is less raised (steep) than at a higher feed or return temperature. With a null correction value, the heating curve remains unaffected. <IMAGE>

Title: Pressure medium control for an injection timing device
Inventor: NOLTE ALBERT
IPC: G05D16/20
Filed: 1984-02-18
Abstract: A device is proposed for the control of a pressure medium pressure for a pressure medium-controlled injection timing device of an injection pump which without any recirculation predetermines the actuating pressure as a function of electrical control pulses of an electrical control device determining the rated value. The control pulses are converted by a stepping motor (3) into a rotary position of a rotary slide valve (4) corresponding to the electrical rated value of the pressure medium pressure. A sleeve (5), which is fixed to a diaphragm (6), slides axially on the rotary slide valve (4). A pressurised pressure medium enters the pressure chamber defined by the diaphragm (6) by way of a throttling port (13) and leaves this, controlled by a bevelled edge arranged on the end of the sleeve (5) projecting into the pressure chamber, by way of a discharge aperture (15) which reduces the pressure to the rated value. The rotary position of the rotary slide valve (4), by way of the bevelled edge (14) determines the height of the sleeve (5), which, by way of a spring force of a spring (7) directed counter to the compressive force, predetermines the control value of the pressure (Fig. 1). <IMAGE>
