Patent DE-3642909-A1 (DE)
Title: Device for compensating rotary impulses
Inventor: FRIEDMANN OSWALD
IPC: F16F15/30
Filed: 1986-12-16
Abstract: In a device with a damping device which is provided between at least two flywheel masses capable of rotation relative to one another and which contains at least one slipping clutch, better adaptation of the damping capacity of the device to the respective application and hence optimisation of the damping characteristic of the device and expansion of the possible range of application is achieved by virtue of the fact that the slipping clutch is designed so that the torque transmitted by it can be varied. Such a design of the slipping clutch enables the maximum oscillations of the flywheel masses relative to one another due to the nonuniformity of the torque output by the internal combustion engine to be damped.

Title: Engine (power plant) for missiles
Inventor: KORNAKER WALTER
IPC: F02K7/18
Filed: 1987-02-07
Abstract: The engine consists of an air-breathing ramjet engine having a built-in launch rocket and a common combustion chamber upstream of which there is connected a fuel injector nozzle. The fuel injector nozzle is surrounded by a concentrically arranged pressure cylinder which is supported such that it can be displaced axially. In the front position, the pressure cylinder covers the air inlet openings, which are arranged in the outer casing of the missile, in a gas-tight manner, in order that the solid propellent charge of the launch rocket can be burnt during the launch phase. After launching, the air-inlet openings are opened by axial displacement of the pressure cylinder, so that the air quantity required for ramjet operation can enter the combustion chamber. The measures according to the invention improve, in particular, the overall efficiency of the engine.

Title: Electrode for a magnetic-inductive flow meter
Inventor: BUSCHMANN HEINZ
IPC: G01F1/58
Filed: 1987-04-16
Abstract: In magnetic-inductive flow meters, the measurement electrodes are arranged directly on the channel wall. Because of deposits, in the course of time an electrically conducting connection is produced with the assigned measurement electrode or the ground electrode so that the measurement result is hereby distorted. In order to counteract this, at the measurement electrodes (4, 5) the electrode head (13) is designed essentially in the form of a disc so that with its external edge it protrudes preferably in the form of a cutting edge above the insulating element (14) designed essentially in the shape of a post and is aligned at a distance and essentially parallel to the channel wall area of the flow channel (1) assigned to it. When measurement electrodes are designed in this way, the measurement result is not influenced by deposits. <IMAGE>

Patent DE-3743453-A1 (DE)
Title: Circuit arrangement for short-circuit protection of a semiconductor amplifier element
Inventor: WODNIOK HUBERT DIPL ING
IPC: H03K17/082
Filed: 1987-12-22
Abstract: The circuit arrangement prevents a semiconductor amplifier element being overloaded as a result of a short circuit. A current-limiting device, which becomes effective immediately, prevents the destruction of the amplifier element in the event of a powerful short circuit, before disconnection occurs. In the event of a longer-lasting overload, the semiconductor amplifier element is disconnected after a delay time. After a further delay time, the disconnection time, the semiconductor element is switched on once again. If the overload is still present, then disconnection and switching on are carried out once again, and this process is repeated periodically. The circuit is constructed such that the switching-on time is inversely proportional to the strength of the short-circuit current.
Patent DE-3744651-A1 (DE)
Title: Glass blocks made of disposable glass containers, and the associated device
Inventor: LE THANH-SON DIPL ING
IPC: E04C1/42
Filed: 1987-12-30
Abstract: Disposable glass containers or disposable glass bottles can be designed in such a way that, after use as liquid containers, they can be used further as glass blocks for building purposes. For this purpose, the bottle body is designed as a hollow prism in such a way that it can be used, after separation of the bottle neck, as a glass block. In order to be able to carry out simple separation between the bottle neck and the bottle body without the latter being damaged during the process, the disposable glass bottle has, at the transition between the bottle neck and the shoulder of the bottle body, a circumferential sharp notch, whose base is partially scored prior to separation using a suitable device, such that the bottle neck can be broken away from the bottle body with one manipulation. The bottle body now separated from the bottle neck constitutes a hollow prism with a round opening on one surface and can then be used as a glass block.

Title: Stethoscope with device and method of recording, evaluating and displaying different biosignals
IPC: A61B5/332
Filed: 1988-02-13
Abstract: Stethoscopes have hitherto been used exclusively for auscultation, whereas biosignals such as ECG, PCG, various pulse curves, Korotkoff's sounds and the like are recorded with the aid of expensive recording instruments. The invention comprises a stethoscope which is provided with a variety of sensors and an electronic evaluator which combine the above-named aspects in one unit (see Fig. 1, summary presentation). During auscultation this device simultaneously records, evaluates and displays biosignals, and this leads to the doctor providing a precise diagnosis. It is possible to classify the sound phenomena as systole or diastole and to make objective statements about the frequency, volume and duration of sounds. Because of its low weight and small size the stethoscope with this accessory is predominantly suitable for preliminary examinations (e.g. home visits of the general practitioner) or for continuous clinical monitoring. <IMAGE>
