Title: Antenna array
Inventor: SOLBACH KLAUS DR ING
IPC: H01Q21/00
Filed: 1987-07-14
Abstract: Modules are proposed for the antenna array having a plurality of individual radiating elements which are arranged in one or more radiating element rows supplied serially row by row. These modules are all of identical construction and contain both active radiating elements with amplifiers and adjustable attenuating elements and phase shifters as well as sections of the connecting line (which is used for serial supply) and the directional couplers for coupling of the active radiating elements. This results in low power losses and simple construction, with infinite interchangeability of the modules, with high flexibility with respect to formation of the polar diagram.

Inventor: KESSEL BERNHARD
IPC: E03F7/04
Filed: 1987-09-17
Abstract: In sparsely populated areas, it is sufficient to provide the sewage conduits at any point with an inspection or cleaning chamber in order to be able to clean the pipes. As soon as the development area becomes more densely populated, backflow occurs in the pipe network if the pipes are not adequately dimensioned. To prevent damage due to backflow, backflow seals are installed, for which purpose the pipe laid in the cellar floor has to be chiselled out and replaced by a backflow sealing unit. It is necessary to put in place different backflow devices depending on whether excrement-free or excrement-containing sewage flows through the pipes. To be able to introduce, according to the sewage system, the correct cleaning pipe with the required backflow seal inexpensively for the building owner, a cleaning pipe is proposed in which optionally two sets can be introduced for the inspection chamber (3) of the basic body (2), each one of which consists of a sealing cover (11) and at least one backflow sealing flap (12, 13) which is at least functionally connected to the sealing cover (11), the basic body (2) forming with the first set (A) a backflow device (1A) for excrement-free sewage, i.e. the backflow sealing flap (12, 13) in the normal operating state is suspended freely oscillating in front of the passage opening, and forming with the second set a backflow device for excrement-containing sewage, i.e. the backflow sealing flap in the normal operating state is held so as to keep the passage opening clear.

Abstract: An arrangement in a television receiver in which a sychronized external power stage supplies operating voltage to a remote-control receiver and a microprocessor connected thereto. A horizontal drive circuit is controlled by the microprocessor, and a horizontal end stage is connected to the horizontal drive circuit. The external power stage supplies power during stand-by operation only to the remote-control receiver and microprocessor along with the voltage for operating the horizontal drive circuit and the end stage. Thyristors are connected to the external power stage for supplying power to all other circuit stages in the television receiver. The thyristors have gate electrodes activated by the horizontal end stage for cutting off the thyristors during the stand-by operation and interrupting the supply of power to all other circuit stages in the television receiver, for minimizing the power consumption of the television receiver.
Patent DE-3738450-A1 (DE)
Title: Die for diecasting
Inventor: WEINMUELLER WERNER
IPC: B22D17/22
Filed: 1987-11-12
Abstract: The invention proposes a die for diecasting which consists of steel or a steel alloy. At least the surfaces which come into contact with molten metal during casting are coated with a hard material (20). A preferred material suitable for use as the hard material is a hard metal, especially titanium nitride, or a ceramic material, such as corundum or the like. This coating of hard material reduces wear on the surfaces of the die (10, 11) which come into contact with the molten casting metal, since the hard material has better resistance to the effects of heat, chemical resistance and mechanical resistance to the molten casting metal than steel, and this proves to be a particular advantage with aggressive molten metals such as aluminium or aluminium alloys. <IMAGE>

Title: Method for transmitting a digitally coded audio signal
Inventor: WECK CHRISTFRIED DIPL ING
IPC: H04L1/00
Filed: 1988-02-19
Abstract: To transmit a digitally coded audio signal consisting of a sequence of information blocks, the digitally coded audio signal is first subjected to a channel coding dimensioned in accordance with the desired error protection at the transmitting end. Then the channel-coded audio signal is transmitted via a highly noisy channel, for example by means of terrestrial or satellite broadcast transmission. At the receiving end, finally, the transmitted audio signal is subjected to a channel coding, during which an error correction is effected. To optimise the channel coding with respect to a minimum bit rate and a maximum error protection, a variable bit error protection is provided in dependence on the different significance of the individual binary positions of each information block, using a convolution code, known per se, for the channel coding.

Title: Device for detecting the rotational speed of a shaft
Inventor: REDLER MARTIN
IPC: G01P3/487
Filed: 1988-10-14
Abstract: The invention relates to a device for detecting the rotational speed of a shaft. In a measuring arrangement, the shaft is connected to a co-rotating permanent magnet having at least two diametrically opposite poles of the same polarity. In two likewise diametrically arranged induction coils, rectified voltage pulses are produced when the induction coils are connected in series with different directions of rotation of the turns, since although the changes in flux due to the magnetic field of the permanent magnet are equal in absolute terms they have different signs. Voltage pulses induced by homogeneous interference (disturbance) fields are compensated in the case of this coil circuit. Also suitable for the purpose of compensating the voltage pulses due to interference fields is a further measuring arrangement having an induction coil which extends in the radial direction, and having a further induction coil, which is arranged extending in the same direction as the first induction coil, but tangentially with respect to the sense of rotation of the shaft. In the case of series connection of the two induction coils having different directions of rotation of the windings, the voltage pulses induced in the two induction coils due to interference fields are subtracted. An appropriate plurality of induction coils can be connected in series in a suitable way in order to double the useful signal. The measuring arrangements are insensitive to magnetic interference fields, as a result of which an enlargement of the measuring range ... Original abstract incomplete.

Abstract: The invention relates to the direct detection of human papillomavirus DNA. The recently developed polymerase chain reaction has been modified in order to improve sensitivity and specificity. It is possible, by choosing suitable oligonucleotide primers (amplimers) and reaction temperatures, for individual HPV genes to be identified among the total cell 4 DNA and amplified to such an extent that non-isotopic detection is possible. In addition, the use of reverse transcription allows deliberate amplification of spliced mRNA and thus an indication of premalignant or malignant states or lesions.

Title: Emergency call system in crash barriers
Inventor: HAMBERGER MICHAEL
IPC: E01F9/669
Filed: 1989-01-19
Abstract: By installing two circuits (circuit 1 and circuit 2) and fitting a cable to the rear side of the crash barrier the rescue services are alarmed automatically. These two circuits are connected to one another by means of a relay which opens and closes the circuit 2. Circuit 1 (relay - crash barrier - power supply - relay) is a closed circuit. Circuit 2 (relay - alarm centre - power supply device - relay) is an open circuit. When the crash barrier is ruptured the cable is damaged at the same time and in consequence circuit 1 is interrupted. By means of a relay circuit 2 is closed and an alarm is automatically triggered in an alarm station (police or the like). The rescue operations are then arranged from this centre. This automatic emergency call system is to save valuable time for rescue measures and human life is to be saved thereby. This system is suitable to be used above all at riverside/shoreline roads and mountain roads.
