Title: Device for open-end friction spinning
Inventor: STAHLECKER FRITZ
IPC: D01H4/16
Filed: 1983-12-14
Abstract: In a device for open-end friction spinning, having rollers which are arranged next to one another and are driven in the same direction and which form a wedge-shaped nip serving as a yarn-forming zone, the wedge-shaped nip is subdivided in its longitudinal direction into at least two portions of differing friction effect which are each formed by a pair of rollers. The portions having their own respective pairs of rollers permit a very high variation during the yarn formation, so that the best possible adaptation to the fibre material to be spun can be carried out.

Title: Method and optical measuring apparatus for detecting toxic compounds by motility measurement
Inventor: SCHMIDT HANS RAINER DR
IPC: G01N33/18
Filed: 1983-12-14
Abstract: A method used for detecting toxic compounds entails determining the motility (active movement) of minute organisms (e.g. Artemia salina L.), which are present in test tubes, with the aid of an optical measuring apparatus. To do this, the light pulses which are generated by the interruptions in the ray path, as a consequence of the movement of the minute animals which are located between a lamp and the light-sensitive detectors, are recorded by the light-sensitive detectors over a defined time period, electronically amplified and counted or further processed. It is possible by incorporating a filter or change in the light source to use particular wavelength ranges for the measurement. The measurement time can be varied in order to be able to use the method also for effects which occur very rapidly. Disturbances due to agitation on introduction of the samples can be suppressed by an adjustable delay of the start of measurement.

Title: Method for suppressing sound and a circuit arrangement and sound-protection device to carry out the method
Inventor: PEEVERS MATTHEW
IPC: A61F11/14
Filed: 1984-03-28
Abstract: In a method and device for suppressing sound, an interfering sound emitted from a source is picked up by a sound recorder (10; 74; 96). The interfering sound signal which is converted by the sound recorder into an electric signal is split in a branching circuit (12) over three separate signal paths. In the first signal path (14), the signal is passed through a low-pass filter and subjected to a phase shift of 180 DEG . In the second signal path (20), it is also passed through a low-pass filter and furthermore subjected to a delay. On the third signal path (26), specific required signals can be transmitted in unmodified form via a bandpass filter arrangement (28). All three signal paths are combined in a unifying network (30) to form a composite signal (32) which activates a sound transmitter (34; 70; 100). The compensation sound generated by the sound transmitter (34; 70; 100) is added to the interfering sound so that they cancel one another. <IMAGE>

Title: Method and device for triggering electrical signals
Inventor: LEHMANN BERNHARD DIPL ING
IPC: G01P5/26
Filed: 1984-05-18
Abstract: In the case of a method for triggering electrical signals for the purpose of initiating their metrological or control-engineering detection, the passages of the noisy signal are detected by means of the electrical voltage value 0, or another defined nominal value. The passages start at the time of their occurrence by initialising an electrical process which is defined in time and is stopped the next time the voltage passes through said value, or an agreed subsequent transmission, and produces a trigger pulse, in order to initiate the electrical signal detection, on reaching a defined electrical state within the start/stop time interval. After initiating the trigger pulse or after stopping the electrical process which is defined in time, said process is reset to its initial state in order to be initialised in a rapid time sequence of further successive detected passages through the nominal value of the signal-noise mixture. <IMAGE>

Patent DE-3419496-A1 (DE)
Title: Arrangement for preventing heat loss
Inventor: KAMPFENKEL OTTOMAR
IPC: F16L59/06
Filed: 1984-05-25
Abstract: Electrical stores have a storage container which is surrounded by insulation which, for its part, is covered on the outside by a housing. The insulation is perforated in order to hold pipe connections and fittings. In this case, a thermal flow forms in the insulation, which thermal flow leads to heat losses which cannot be ignored. In order to minimise these heat losses, it is ensured that the underneath of these spaces forms the coolest surface of the space. This can be achieved by means of a heat-reflective layer or a heat-disippation layer, especially by means of an aluminium foil.

Patent DE-3419950-A1 (DE)
Title: Stitch type and process and apparatus for producing it
Inventor: CONTI ROBERTO
IPC: D05B1/02
Filed: 1984-05-28
Abstract: The invention relates to a stitch type, in which the thread forming the stitch is alternately visible and invisible between adjacent through-stitches on one side of the sewing material. So that an unravelling of a seam formed from such stitches can be prevented and continuous threads can be processed, the thread is guided in a single strand through the vortex of a thread loop running back and is thereby interlaced with the loop. The interlacing is carried out essentially in that the thread loop running from one through-stitch to the other is guided round the thread supply. An apparatus which is suitable for producing the stitch type comprises a thread-loop catcher which guides the thread loop around the entire thread supply.

Title: Oil filter for cleaning lubricating oil
Inventor: BAUMANN DIETER
IPC: B01D35/153
Filed: 1985-10-30
Abstract: In an oil filter for cleaning lubricating oil, especially for internal combustion engines of motor vehicles, an annular filter cartridge to be inserted into an inclined filter housing carries an elastic sealing ring on its bottom end face which engages in an annular depression in the base of the filter housing. A drainage duct for draining the filter housing opens into the depression and when the oil filter cartridge is fully inserted is sealed off from the filter housing by the sealing ring. The oil to be cleaned is fed to the peripheral area of the oil filter cartridge and after cleaning passes into the central internal area from where it can flow to an oil outlet. The sealing ring sealing off the annular depression radially inwards and outwards also prevents any direct flow connection between the oil inlet and oil outlet. As soon as the oil filter cartridge is withdrawn at least partially from the filter housing, the sealing ring moves out of the area of the depression so that residual oil can flow into the drainage duct. In a further embodiment the sealing ring may have an external sealing lip, which when the oil filter cartridge is fully inserted only permits a flow in the normal oil flow direction and, like a non-return valve, prevents any return flow when the oil circulation is at a standstill, as when the engine is shut off. This sealing lip ... Original abstract incomplete. <IMAGE>
