Title: Circuit arrangement for evaluating the signal voltage received from an active burglary alarm system
Inventor: STRIETZEL RAINER
IPC: G01S13/04
Filed: 1982-10-02
Abstract: In an active burglary alarm system which operates by means of ultrasound, radio frequency or infrared, the signal voltage (Ui) contains, apart from the actual signal which is generated by the intruder, a further signal component which is caused by ageing, contamination or failure of the functionally essential components. To eliminate this slowly changing signal component, the evaluating circuit contains a first time delay section having a short time constant and a second time delay section (T2) having a long time constant, the output signal of which is subtracted in a differential amplifier (DV) from the output signal of the first time delay section. The output signal of the differential amplifier (DV) is applied to a first window discriminator (FD1). The output signal of the second time delay section (T2) is also applied to a second window discriminator (FD2) which responds when ageing, contamination or failure exceed a tolerable limit. <IMAGE>

Title: Method for determining the electrical-energy quality characteristics of a three-phase system and devices for carrying out this determination
Inventor: SIDLOVSKY ANATOLIJ KORNEEVIC
IPC: G01R29/16
Filed: 1982-11-03
Abstract: The invention relates to measuring technology. The method for determining the electrical-energy quality characteristics of a three-phase system is based on the determination of its symmetric components, from the amount of which the magnitude of the electrical-energy quality characteristics is assessed. According to the invention, first the amplitude and starting phase of the reference voltages is determined, then a symmetrical three-phase reference system of the positive-sequence voltages is formed, the starting phase and amplitude of which is equal to the previously determined values of the starting phase and amplitude of the reference voltages and the frequency of which corresponds to the mains frequency, and then the reference voltages are subtracted phase by phase from the input voltages and the symmetric components are determined in accordance with the difference between the input voltages and the reference voltages. A variant of the device for carrying out the method contains a device (20) for measuring the symmetric voltage components of the three-phase system, three adding circuits (14, 15, 16), a controllable three-phase generator (17) and a shaper (18). This invention can be applied most usefully in information and measuring systems for determining the electrical-energy quality characteristics of three-phase systems. <IMAGE>

Title: Apparatus for flow measurement of flowing media
Inventor: TIEFENBACH WILLI
IPC: G01F1/24
Filed: 1983-01-12
Abstract: The invention relates to an apparatus for flow measurement of flowing media, in which a float which is located in the stream of these media flowing through a channel is taken along to a greater or lesser extent by the flow of gases or liquids. This float contains an embedded bar magnet, and a switch fastened on the housing of the apparatus is actuated by magnetic forces whenever a predetermined flow rate is exceeded or not reached. Arranged parallel to the said channel is a second channel, which does not communicate with the first channel and in which an oppositely poled magnet body is mounted easily displaceably by means of fitted-on sliding pieces. This magnet body is taken along by magnetic forces upon displacement of the float and its respective position is visible through a sight glass. This design offers the advantage that, should the sight glass break, there is no effect on the flow of the medium to be measured and persons who are in the vicinity are not endangered by, for example, hot liquids spraying out or gases flowing out. Furthermore, the inside of the sight glass is not soiled by the flowing medium and there is no need for the cleaning work usually required in the case of previous embodiments.

Title: Torsional vibration damper with axial spring movement
Inventor: NAGLER FRANZ
IPC: F16D3/80
Filed: 1983-12-05
Abstract: The invention relates to a torsional vibration damper in which an axially displaceable coupling part provided with restriction apertures is arranged in a leak-tight housing which is at least partially filled with damping fluid. In this arrangement, a spring device, preferably designed as a diaphragm spring, is provided on one side of the coupling part and an axial thrust face and a counter thrust face separated by rolling elements are provided on the opposite side. Starting from the rest position of the torsional vibration damper, the axial thrust face extends towards the diaphragm spring both in the direction of tension and in the direction of thrust. On the one hand, this guarantees a simple construction and, on the other hand, freedom from play during the transition from one direction of loading to the other. The rotationally fixed attachment of the coupling part can be effected either via tangential straps or via the diaphragm spring or via an axially elastic but circumferentially rigid diaphragm.

Title: Device for the relaxation of the human spine and joints
Inventor: KOCH HELMUT DIPL ING
IPC: A61H1/02
Filed: 1984-01-16
Abstract: There is proposed a chair-like device in which the seated user can extend, and at the same time twist, i.e. relax, the thoracic and lumbar spine or the cervical spine with a hydraulic pump by means of lifting movements on shoulder rests or head rests, and this is confirmed by tests. In order to avoid body injuries a safety valve is used to delimit the length of extension and the tensile force; furthermore there is a stop in order to delimit the angular paths. Using a simple embodiment of a self-operated device it is possible to achieve considerable alleviation of the symptoms and pain of physically disabled people and patients with spinal disorders at the workplace and at home by relaxation exercises of the "extension - torsion" movement combination. Alternatively, an externally driven, program-controlled device designed like a chair or a horizontal couch can be used to achieve a relaxing effect on the human spine or the joints by the principle of the "extension - torsion" movement combination. In order to intensify this relaxing effect, the movement sequences can take place on the patient, for example, in a pulsating or vibrating manner, in conjunction with an interval circuit. Such complicated devices are suitable for the curative treatment of spinal disorders and joint disorders of a very wide variety in general practices, in cheiropraxis, in hospitals, in sanatoria, rehabilitation centres, etc.

IPC: G11B20/14
Filed: 1984-06-05
Abstract: A device for recording binary signals on a magnetic information carrier is described, in which a needle pulse of one polarity is applied to a recording magnetic head each time the signals to be recorded change from <<0>> to <<1>> and a needle pulse of the other polarity is applied to the said magnetic head each time they change from <<1>> to <<0>>. The device has either two monoflops or one monoflop. The output signals of the two monoflops are applied to the magnetic head via a summation circuit, whereas the output signal of the one monoflop is applied to the magnetic head via a logic circuit, which reverses the direction of the current in accordance with the data signal applied. Furthermore, a device for retrieving binary signals recorded on a magnetic information carrier is described, which device determines the zero crossing of the read signal. The device has three comparators, which compare the read signal with predetermined threshold voltages. Only if the output signals of the comparators occur in a particular sequence is a received signal identified as a read signal.
