Title: Methods of and apparatus for recording and reproducing analog signals
Inventor: FUKUDA SHINICHI C O PATENT DIV
IPC: H04N5/782
Filed: 1983-04-15
Granted: 1989-05-11
Abstract: For recording an analog signal by means of two recording heads (1A, 1B) equally spaced on a rotating drum (3), a magnetic tape (2) is wrapped around a guide drum (3) with an angular range of 90°, so that there are recording periods when a head (1A, 1B) is tracing the tape (2) and free periods when neither head (1 A, 1 B) is tracing the tape (2). The analog signal to be recorded is converted to pulse code modulated (PCM) signals having real time periods longer than the recording periods. The free periods, during which neither head (1 A, 1 B) is in contact with the recording medium (2), are used to add redundant data such as parity data and a cyclic redundancy check (CRC) code to the PCM signals. The composite signal, which represents a PCM signal having the parity data and CRC code added to it, is time-base compressed to a period substantially equal to the recording periods and is recorded on the recording medium (2) by one of the heads (1 A, 1 B) during its recording period. To reproduce the signal, the same head arrangement is used. The free periods are used for error correction and the error-corrected signal is time-base expanded to occupy the original or real time signal period and then reconverted into the corresponding analog signal.

Title: Method and device for the production of yarn
Inventor: STALDER HERBERT
IPC: D01H4/16
Filed: 1985-07-10
Granted: 1988-10-13
Abstract: A method and an apparatus for production of yarn by friction spinning is disclosed. The friction spinning method employs a perforated friction spinning drum towards which a fibre feed passage projects. An opening roller, known from the open-end rotor spinning process, feeds separated fibres into the fibre feed passage, which fibres are taken up by a transport air flow in the fibre feed passage. This transport air flow is produced by the perforated friction spinning drum which is subjected to underpressure. Fibres leaving an opening of the fibre feed passage are laid in an inclined disposition on the perforated friction spinning drum and transported in this disposition towards a yarn end forming at a yarn formation position. The spun yarn is withdrawn by a withdrawal roller pair. Advantageously, a second friction spinning drum is provided parallel to the first perforated friction spinning drum to cause the fibre twisting-in process to take place in a more accurately defined manner.

Patent DE-3575577-D1 (DE)
IPC: C21D9/52
Filed: 1985-08-17
Granted: 1990-03-01
Abstract: To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage. Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.

Abstract: The injection pump has a pump piston driven with a constant stroke which pumps fuel at injection pressure to an injection nozzle so long as an electrically actuated overflow valve blocks the flow of the fuel overflowing via an overflow conduit to a low-pressure chamber. The overflow valve is a needle valve, the valve needle of which, opening inward toward a pressure chamber that can be placed under injection pressure, by means of a conical closing surface radially defining a needle tip controls a valve seat that widens conically toward the pressure chamber. The cone angle of the closing surface is larger than the cone angle of the associated valve seat and the closing surface forms a sealing edge, the diameter of which is equal to or only slightly smaller than the guide diameter of the guide shank on the valve member. In a preferred embodiment, the needle tip of the valve member has an external contour on its end, adjacent to the closing surface, which directs the fuel flow and reinforces the opening movement. The injection pump is particularly suitable for high-pressure injection in Diesel engines, in order to attain an exact electrical control of the supply onset and supply quantity, if a reservoir chamber defined by a deflecting piston is connected to a high-pressure chamber that includes the pump work chamber.
