Abstract: The present invention relates to a process for recovering and using chemicals when producing cellulose pulp using sulphur-containing chemicals. The chemicals which are recovered from the black liquor are dissolved in order to produce green liquor, which is evaporated in order to crystallize sodium carbonate. The chemicals are dissolved in a liquid which essentially does not contain any sodium hydroxide at all, with the aim of obtaining green liquor for the evaporation-crystallization, which green liquor contains extremely little sodium hydroxide. The sodium carbonate crystals are separated out of the green liquor in order to produce a green liquor which has a high sulphide content. The sodium carbonate crystals are dissolved and causticized in order to produce a solution which has a low content of sulphide.

Title: Stabilized acrylonitrile polymers
Inventor: KRIEG MANFRED DR
IPC: C08F2/44
Filed: 1976-01-12
Abstract: The polymer material, which is based on polyacrylonitrile or a copolymer thereof comprising at least 20% by weight of acrylonitrile and at most 80% by weight of other monomers that are copolymerisable with acrylonitrile, contains a thermostabilising additive comprising an alkyl, cycloalkyl or aryl isocyanate. To produce the polymer material, the acrylonitrile or a mixture thereof with appropriate comonomers is polymerised and the thermostabilising additive is added before or during the polymerisation or allowed to diffuse into the ready-polymerised homo- or copolymer. The effect of the isocyanates can be enhanced by the additional use of an aliphatic thioether or in particular by combination with nitroalkanes. The so protected polymer material is suitable in particular for producing mouldings in a thickness of the polymer material where undesirable temperature-induced discoloration would be particularly noticeable.

Title: Electrical high-speed printers
IPC: G06K15/10
Filed: 1972-01-11
Abstract: 1376653 Printers ROBERT BOSCH GmbH 11 Jan 1972 [12 Jan 1971] 1131/72 Heading G4H  An electrical high speed printer comprises a recording head 17 driven by a motor 16 which is stepped in synchronism with data input to the device and which is switched on at least one step before the recording of the first character in a line of data, so as to ensure distortion-free recording. The printer may be used with a desk calculator 27 wherefrom the motor is operated by sync pulses 12 which also control a cyclic numeral tube display 30. Each recording head 17 (Fig. 3), incorporates seven recording electrodes 20: each step A of the motor is divided by the sync pulses into thirteen increments a, and corresponds to the printing of a character (seven increments), followed by a space (six), with or without a decimal point 38.  When a character button 28 is pressed, the corresponding number is displayed on tube 30b and fed to a buffer 13 in the printer. When a command button ("add", &c.), 29 is first pressed, a control pulse 11 is sent to a control 14 when tube 30a is next triggered by a sync pulse; control 14 actuates a pulse converter 15 which switches on the motor. After one step of the motor (when its follow-up has become constant), buffer 13 is opened by control 14 (when tube 30b is triggered), whose contents (corresponding to this tube), are transmitted to a character generator 22, and thence (in 13 parts), to the recording electrodes. The input and recording of data is then continued with the stepping of the motor (a new character on every 14th pulse so that only one character is fed to the buffer 13 at each cycle of the display tubes 30), until a complete line has been recorded, whereupon a monitor unit 23 causes the control 14 to return the recording head 17 to its initial position. Means for actuating electrodes 20a, 20b to record a decimal point are described (Fig. 5, not shown), together with means for selectively recording the results calculated by 27, or all the numbers which have been fed in and calculated (Fig. 6, not shown).  Instead of recording one character at a time, the buffer 13 may be adapted to store the characters until the number required to form a complete line have been stored, whereupon a switching-on signal is applied to the control 14.

Title: Method of crucible-less zone drawing of very pure low-melting substances
IPC: C30B13/28
Filed: 1963-01-11
Abstract: A molten zone is passed upwards through a polycrystalline rod of gallium or indium antimonide, the lower end of the molten zone being cooled by the upward passage of a stream of gas at a temperature of between 0 DEG C. and the b.p. of nitrogen.  The gas may be hydrogen, helium, or ammonia.  It may be cooled by passage through a gas-washing bottle immersed in a coolant, or by indirect heat-exchange with a liquid coolant.  Alternately, it may be obtained by vaporizing a condensed gas.  The stream of gas may pass at 100 ml/min.  The molten zone may pass at 2 mm/min. According to Fig. 1 (not shown), a molten zone, formed by an induction coil 10, is passed upwards through a rod 2 held between rotary shafts 3 and 4 within a quartz tube 1, the molten zone being cooled by the upward passage of a stream of hydrogen which is itself cooled by liquid air in a jacket 5.

Abstract: 523,956. Electric circuit-breakers. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 16, 1939, No. 1479. Convention date, Jan. 14, 1938. [Class 38 (v)] A power switch operated by compressed gas works in combination with an isolating switch in such manner that after automatic opening of the power switch automatic reclosing if the overload persists takes place twice or oftener within a set period or until the isolating switch is open. In Fig. 1 a power switch a with isolating switch b is operated by means of compressed air in the container c. On manual operation at switch i the circuit is closed through the relay sp2 and switch o3. Energization of sp2 opens valve n, admitting compressed air from c by way of m' to operate piston k, in slide k thus closing the contacts at o, and connecting m2 to m5 by way of k. Closing of o1 closes the circuit by way of q2 and o3 through relay sp, which operates valve d admitting pressure gas to e thus opening valve f and opening the power switch. Pressure gas from behind f passes by way of m, to q, making a holding circuit for relay sp1 and by way of k and m5 to means g for operating isolating switch. This opens o3 by which all other parts of the circuit return to normal. On operation of protective relay b the circuit is connected by way of q2 and o, through relay sp, which as before opens the power switch and admits pressure gas to k by way of m2. Since k, is in its initial position, the pressure gas passes through m4 to chamber p, where pressure builds up to open valve P11and then passes by way of m3 to close power switch a, to operate q2 so as to transfer the protective relay circuit to sp2, and to chamber P2. q, has meanwhile maintained a holding circuit for sp,. If, on closing a the protective relay h does not operate again the pressure accumulating in p2 operates after a time lag to open the holding circuit for sp1 and to vent the system by way of m22, m, and opening r2. If h does operate on closing a, sp2 is energized opening n and moving k, so that pressure gas from m2 is transferred from m4 to m5 and pressure is allowed to escape from m3 by way of m33, k1 and opening r3. Thus a is reopened, for abutment k3 maintains k2 so as to keep o2 closed, and g is operated. As before the opening of g breaks circuit at o3, and the system is returned to initial position.
