Patent EP-0046588-B1 (EP)
IPC: H04B3/03
Filed: 1981-08-22
Granted: 1985-07-03
Abstract: The transverse and longitudinal termination impedances of a subscriber line interface circuit may be independently controlled. The equivalent termination impedance of a subscriber line/trunk appearing to the central office can be adusted upward or downward from a lower resistance value, with longitudnal balance being determined by the matching of feed resistors. The circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits; all resulting in an improved telephone line interface circuit. Voltage or current feedback to synthesize the proper ac transverse termination impedance from a known dc resistance, is utilized the feed resistors in a telephone line circuit. The transverse and the longitudinal termination impedance are determined by choice of feed resistance value. The independent control of transverse impedance is achieveable as a result of the feedback circuitry being nonresponsive to longitudinal signal.

Abstract: The cooling of a cast steel slab in a continuous casting installation is controlled by dividing the cast product into successive fictitious elements and periodically calculating the water flow values of the cooling water delivered to the successive cooling sections in the secondary cooling zone of the installation as a function of the age of the elements in these sections. The quantity of heat extracted in the mold is taken into account by periodically determining the water flow values in the different zones by means of a computer on the basis of a first curve giving the variations of the quantity of heat extracted from a unitary mass of the cast product as a function of the time while the cast product passes from the point of emergence from the mold to at least the zone of solidification, and a second curve giving the variations of the surface temperature of the cast product during this passage as a function of time. Before each calculation of the water flow values, the first curve is corrected in direct dependence on the quantity of heat extracted from the product in the mold.

Abstract: Method for rapid determination of biochemical data for microorganisms. Microorganisms in a sample are bound to an adsorbent, which usually is a carrier, provided with antibodies corresponding to the microorganisms that shall be adsorbed. After washing for removing of all non-specifically bound cells a nutritient medium is added in order to start the metabolism of the cell. For this metabolism certain substances must be present, and products are produced simultaneously. This fact is utilized for the determination of the amount of microorganisms, for instance by measurement of the amount of consumed oxygen, produced carbon dioxide, change of pH-value or electrical conductivity in the nutritient medium. Calibration curves are used for the determinations. The method can also be used for the determination of the concentration of biochemical substances, which influence the metabolism of the cell, for instance vitamins and antibiotica. At the determination of the vitamin content, a microorganism that can only metabolize when the vitamin in question is present, isadded to the adsorbent. The degree of metabolism is dependent on the amount of vitamin, which can be determined by comparison with a calibration curve. At the determination of inhibiting substances, like antibiotica, a predetermined amount of a predetermined microorganism is added to the adsorbent. The sample containing antibiotica is added and any change of the products from the metabolism, for instance in the form of a pH-value change is observed. The amount of antibiotica in the sample can be determined by comparison with a calibration curve that has been obtained with known amounts of antibiotica.

Abstract: A method of purging waste gases by adding to the gas, while it flows through an absorber, a neutralizing agent, such as lime, together with a liquid substance under such conditions that the liquid is evaporated and that a dry salt is left as reaction product. The absorption results in a reaction of the noxious compounds in the waste gases with the neutralizing agent, whereby dry salts are formed, which are removed from the absorber. The same neutralizing agent in the form of the aqueous solution or aqueous suspension may be used as the liquid substance. The liquid substance is supplied into the absorber downstream of the neutralized agent in the solid pulverized state.

Abstract: For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator. Invalid channel words are provided with an invalidity bit in the demodulator. During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways. When too many words of a group of code words are invalid, all words of the relevant group are invalidated. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words.

Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.

Title: Line with divided low-pass filter
IPC: H01B11/18
Filed: 1983-06-29
Granted: 1987-01-14
Abstract: For suppression of high-frequency spurious signals (noise) present on an electrical transmission line, the line incorporates at least one section comprising a distributed low-pass filter. This section is constructed so that its wave impedance (Z1) has a different value than the wave impedance (Z0) of the neighboring line sections. This filter line section additionally provides considerable dielectric losses and/or skin effect losses. At both ends of the filter line section, at which the wave impedance changes, multiple reflections arise that attenuate the high-frequency spurious signals (noise). The dielectric or skin effect losses produce strong attenuation of the undesired resonances that arise from the reflections, as well as further attenuation of spurious signals in the highest frequency region.
