Title: Holding or clamping pincers, in particular for measurements on injection lines of diesel engines
Inventor: GAWANKA JOACHIM
IPC: B25B7/12
Filed: 1984-10-25
Abstract: The holding or clamping pincers for gripping and holding bodies are suitable in particular for measurements on injection lines of diesel engines and have on the leg (4) of one clamping jaw (1) a locking bolt (6) which is supported in the clamping positions on the opposite leg (5) of the holding pincers so as to lock under the action of a spring. A pressure-sensitive measuring body (7) is arranged on one of the two clamping jaws (1, 2) and has a pressure cap (8) which protrudes towards the other clamping jaw (1) and is connected to an electromechanical energy transducer (9) with piezoelectric properties. The clamping jaw (1) which lies opposite the pressure measuring body (7) has clamping faces (11, 12) which are directed in an approximate wedge shape one towards the other and extend parallel to the rotary joint (3) between the two clamping jaws (1, 2), so that such pincers can be attached at any desired point of an injection line without any additional expenditure in terms of tools. The stretching of the line during the injection process is detected by the measuring body (7) with two piezoelectric ceramic bodies which are connected fixedly to one another. A contact pressure which remains constant in each case is ensured by the two helical pressure springs (18, 21) and the locking bolt (6) which is easy to undo manually. The pincers can not become released from the line by themselves. <IMAGE>

Title: Damming element for damming and limiting areas of water
Inventor: FABRITZ GERHARD
IPC: E02B15/04
Filed: 1985-03-18
Abstract: The damming element according to the invention consists of a floatable, tubular body of pear-shaped cross-section and is universally usable in the field of water supply and distribution. The ends of the tubular body are closed watertight with identical caps. These caps are cylindrically arched to the outside, the axes of the cylindrical arches being disposed perpendicularly to the water surface. The end of the pear-shaped cross-section is of stem-shaped design and a circular profile adjoins it. The circular profile has a through-bore which runs parallel to the centre axis of the tubular body. A rope, preferably a steel rope, is pulled through the said bore and thus any number of damming elements according to the invention can be pulled up side-by-side to form a chain. The steel rope is fastened to the banks to dam stretches of water. The cylindrical arches of the caps result in linear contact between the damming elements, which is retained even in the event of drifting of the damming elements. The linear contact is especially important during the waste disposal from oil-contaminated stretches of water, because no oil can thereby flow off between the damming elements.

Title: Savonius-type wind rotor with improved rotor blades and boosters
Inventor: NOELKEN FRANZ DR
IPC: F03D3/06
Filed: 1985-06-01
Abstract: By modifying the semi-cylindrical form of the Savonius rotor blade to give it greater curvature, which then passes into a straight surface, an improved wind intake is achieved. In addition the wind feed is increased by two boosters in the form of baffle plates fitted to the right and left of the rotor. On each baffle plate a narrower baffle plate is mounted by means of a wedge-shaped separator so that the opening of the wind inlet is greater than that of the outlet (orifice to the rotor), so that the wind acts on the rotor with greater force.
Patent DE-3520488-A1 (DE)
Title: Alternating-current electromagnet
Inventor: THOMSEN UWE
IPC: H01F7/12
Filed: 1985-06-07
Abstract: The invention relates to an alternating-current electromagnet whose electromagnetic circuit consists essentially of the coil, the yoke and the plunger-type armature which can be displaced in an axially guided manner. This armature is fixed with the aid of a spring-loaded compression element, which is guided in a sliding manner on a fixed-position conical surface and without play with respect to the plunger-type armature, against radial oscillations, in order to prevent noise being produced by oscillation of the armature. Such noises can be suppressed particularly effectively and easily in that the compression element is constructed as a guide ring which surrounds the plunger-type armature concentrically, whose circumference can be deformed elastically and which, on one side, rests with a conically drawn-in surface on the abovementioned conical surface, and on whose other side a compression spring acts.

Title: Direct current transmission circuit
Inventor: KNICK ULRICH DIPL ING
IPC: G08C19/02
Filed: 1985-07-27
Abstract: In the case of a direct current transmission circuit without auxiliary energy for DC-isolated transmission and/or conversion of the magnitude of a measurement current, the measurement current is converted into alternating current by means of at least two switching transistors (9, 10) whose bases are alternately switched on by means of a control circuit (15, 18-20), is transmitted by means of a transformer (3) and is rectified again on the secondary side of the transformer (3). In order to reduce measurement errors in the transmission circuit, it is ensured that the control voltages on the bases of the switching transistors (9, 10) and the voltage on the transformer (3) are sinusoidal when the measurement currents are small and that, when the measurement current rises, these voltages make a continuous transition from the sinusoidal form into a largely rectangular form. <IMAGE>

Title: Evaluation electronics for differential photodiodes
Inventor: HABERLAND RUEDIGER PROF DR ING
IPC: G01S7/4861
Filed: 1985-09-03
Abstract: In the case of evaluation electronics for differential photodiodes having a pulse-width-modulated rectangular output voltage, in the case of which a capacitor is charged alternately by means of in each case one photocurrent of the two photodiodes of the receiver up to a comparison voltage and subsequently has its charge changed to a second comparison voltage, the measured value is strictly proportional to the measurement variable, after low-pass filtering. The stability of the capacitor which is to be charged is irrelevant in this case since the same capacitor is charged via the photodiodes in each charging cycle so that said evaluation electronics are suitable for precision applications. The circuit is furthermore characterised by its simple construction, low number of parts, small space requirement and low costs.
