Abstract: The tamping machine comprises, for each row of rails (6) a tamping unit (4) which is movable in the transverse direction of the track in order to tamp the track switches. The controlled transverse mobility of each tamping unit, to the right and the left of the line of rails, is obtained by the combination of a lever manual control member (26) and an automatic control circuit (38) which is controlled by two amplitude limiters (34, 36). A switch (32) makes it possible to change from manual to automatic and vice versa. By presetting the amplitude limiter at a value corresponding to a transverse position of the tamping unit which is repeated several times along the track switch, the positioning of the tamping unit is obtained by simple actuation of the switch upon arrival at these recurrent positions.

Abstract: The susceptibility of compressors, expanders and noise reduction circuits to undue control by signals outside the passband(s) in which the circuits are active is reduced. In a compressor which operates by narrowing the pass-band of a variable filter 22, the conventional feedback control via rectifier 31 and smoothing means 31, 32a, 32b is counteracted by a further signal derived from a wider frequency region by a rectifier 31' and smoothing circuit 32a'. The further signal bucks the main control signal in combining circuit 33. Similar arrangements are disclosed for arrangements using variable gain circuits instead of a variable filter and alternative arrangements use multichannel control signal circuits having limiters with different thresholds whereby the control signal is tailored to achieve like results. All arrangements reduce the circuit response to signal components outside the pass band(s) at high input signal levels. <IMAGE>

Filed: 1982-03-23
Abstract: Filter for fibrous material is disc type and has hollow shaft down which passages run. A series of segmental discs are located along the shaft with each segment having a passage which connects with the passage down the shaft. A distributor valve permits alternating press. and suction to be applied to various passages as the shaft rotates. This distributor valve establishes a suction zone around a certain sector, this being divided into parts. The first serves to draw off the so-called dirty filtrate while the second draws off the clean filtrate. Suction in the clean zone commences somewhere between the lowest posn. of the radius and 60 degrees round from this esp. in a zone 10-50 degrees round from the lowest posn. Suction for the dirty filtrate commences at least 45 degrees before the lowest posn. Used to filter fibrous slurries esp. wood pulp slurries inppapermaking. The filter operates significantly quicker and more precisely than previous disc filters.

Abstract: A method of recovering chemicals and heat in sulphate spent liquor by means of A1(OH)3 or TiO2.n.H2O circulation and gasification of the waste liquor The invention relates to a method of recovering chemicals and heat in sulphate spent liquor, wherein evaporated black liquor is granulated by means of circulated A1(OH)3 and NaA102 or TiO2.n.H2O and Na2TiO3, whereafter the granules are fed into a spent liquor gasifier where the temperature is from 700 to 1250.degree.C. The granules which do not contain carbon, organic matter or sulphur are discharged from the gasifier, cooled with air and crushed, whereafter a part of the sodium aluminate or sodium titanate formed, if desired, is circulated to granulation and the remainder is dissolved in water. Hereby either NaOH and TiO2.n.H2O is formed which is precipitated or recirculated, or, when using A1(OH)3 circulation, an alkaline aluminate solution which can be directly used as absorption solution for H2S or cooking liquor in sulphate cooking. A1(OH)3 can also be precipitated from the solution and recirculated to granulation, whereby the remaining mother liquor mainly containing Na2CO3 is passed to causticizing. The gas mixture obtained from the gasification of spent liquor is cooled, whereafter H2S is absorbed from the gas into the NaOH solution or directly into the alkaline aluminate solution. The obtained solution is passed to the preparation of cooking liquor, and the flue gas is burned.
