Patent DE-3633914-A1 (DE)
Title: Turf perforated brick for improved drainage of rainwater into the subsoil
Inventor: MIELKE HORST GUENTER DIPL BIOL
IPC: E01C5/00
Filed: 1986-10-04
Abstract: The turf perforated brick for improved drainage of rainwater into the subsoil is in two parts. It consists of a grid frame and a plate. It can be laid on all ways (paths) and squares. The grid frame enables three-dimensional stability of the turf perforated bricks with respect to one another. Together with the covering plate, it ensures a non-compressible retention space for short-term water retention. The surface connection reduces compaction of the subsoil and increases, along with the retention space, the seepage rate of the rainwater.

Title: Electrical engineering measures for the attenuation and suppression of radio-frequency signals on electrical lines
Inventor: KILLESREITER HERMANN DR RER NA
IPC: H04B15/00
Filed: 1986-10-31
Abstract: The patent claim concerns electrical engineering measures for the attenuation and suppression of radio-frequency signals on electrical lines. The technical problem is that radio-frequency signals can occur on the electrical supply lines from different sources and for different reasons, including terrorist activity, said signals turning the lines inside buildings into transmission antennas and thereby exposing people to the resonance effect of electromagnetic waves. The solution to the problem entails the interruption of the supply lines at the generator output and consumer input points and the intermediate insertion of corresponding electrical engineering attenuation and suppression components. The invention can be used to meet environmental and therefore also health and safety requirements.

Patent DE-3703533-A1 (DE)
Title: Mechanical seal
Inventor: STEIN KARL VOM
IPC: F16J15/36
Filed: 1987-02-06
Abstract: In a mechanical seal with a fixed slip ring and a preferably fixed sealing bellows which at least partially overlaps the slip ring in the region of one circumferential surface and, in the region of its circumferential surface facing away from the slip ring, ends in an approximately axially extending retaining part, and with an approximately conically wound compression spring which rests on the sealing bellows at the retaining part and at the slip ring, the sleeve part of the sealing bellows consists of a separate component composed of more resistant material than the remaining part of the sealing bellows. The sealing bellows and the sleeve part are connected non-positively to one another and, as a result, the seal is resistant even to very aggressive media in the sealing part subject to dynamic loading and in the connecting region and remains functional even after a prolonged period in use. To promote the non-positive connection, axial projections of the slip ring can engage in recesses in the slip ring to safeguard against rotation. <IMAGE>
Patent DE-3712953-A1 (DE)
Inventor: BUETTNER RUDOLF
IPC: B24D5/12
Filed: 1987-04-16
Abstract: A cutting tool comprising a disk, on the periphery of which are mounted cutting segments. The cutting elements have grooves which extend over the entire height of each cutting segment and have channels discharging chip material in peripheral direction. The latter are in particular meander-shaped, zigzag-shaped or wave-shaped, with the cutting-segment surfaces being opposite one another conformingly parallel in such a manner that a full cross-sectional overlapping is assured in an axial direction. Side channels and/or V-channels can follow a center channel in order to also permit a lateral material discharge.
Patent DE-3716064-A1 (DE)
Title: Modulator for generating an amplitude-keyed radio-frequency signal
Inventor: LOGEMANN JOERG DIPL ING
IPC: H04L27/04
Filed: 1987-05-14
Abstract: A modulator for generating an amplitude-keyed radio-frequency signal contains a counter started by the audio-frequency keying signal with each keying, which counter generates the signal edge of a linearly falling or rising ramp. This linear signal is used for addressing a read-only memory which outputs a control signal for a rounded non-linear edge characteristic. The control signal is applied to the digital input of a D/A converter with a resistance network, at the reference voltage input of which an unmodulated RF signal is present. After filtering and amplification, the analog output signal of the D/A converter forms the amplitude-keyed RF signal.

These flaps are arranged so as to be pivotable from a position cooperating with the ball surface into an ineffective position free of the ball surface. <IMAGE>
Patent DE-3724191-A1 (DE)
Title: Tank with a closable opening
Inventor: STEIGER ALOIS
IPC: F24H1/18
Filed: 1987-07-17
Abstract: Hand holes or similar openings in tanks are frequently produced with a rim that is drawn inwards (necking), the thickness of the material being considerably reduced at the drawn edges. In the case of another solution, an annular part is welded on or in the opening, leading in the case of special-grade steels to a disadvantageous alteration of the surface in the region of the weld. A tank with a curved wall or an arched end and an elliptical or oval opening which can be closed by a corresponding lid (10), preferably one which rests against the inside, has an outward-projecting neck (6). This comprises a flat annular surface (3), within which there is an outward-projecting reinforcing rim (5), and merges into the curvature of the end (1) via two deformation sections (8, 9), of which at least one has a variable slope over its circumference around the hole. The invention is preferably employed on arched ends of hot-water tanks made of special-grade steel but is not limited to these. <IMAGE>

Patent DE-3729977-A1 (DE)
Title: Multi-pole generator
Inventor: SCHIPPER THOMAS
IPC: H02K21/24
Filed: 1987-09-08
Abstract: The multi-pole generator consists of at least one magnet, at least two pole shoes and at least one winding disc. The winding disc is arranged between the pole shoes and can optionally be used as a stator or rotor. The field of the magnet is split into n poles in the gap between the pole shoes. The arrangement of the windings produces a current flow in the form of one positive and one negative half-cycle per pole-shoe segment per revolution, without reversing the magnetic field. This results in an alternating-current flow having n cycles per revolution, as a result of which the multipole generator is particularly suitable for slowly running operation.

Title: Balancing arrangement
IPC: G01M1/36
Filed: 1987-12-21
Abstract: In order to be able to operate an electrically operable balancing arrangement (2) for rotating parts such as, for example, grinding wheels, in a wire-free manner, an electric generator (11) is provided, which obtains the operating energy for the balancing arrangement from the rotation of the part to be balanced.
