Title: Process for treating calcium sulphate from flue gas desulphurisation units
Inventor: SCHNEIDER HEINZ DIPL CHEM DR
IPC: C01F11/46
Filed: 1982-05-08
Abstract: In a process for treating calcium sulphate from flue gas desulphurisation units which are operated on a lime base, the calcium sulphate withdrawn in the form of the dihydrate from the flue gas desulphurisation unit is reacted with an aqueous solution of ammonia, ammonium carbonate or ammonium bicarbonate or a mixture thereof and with carbonic acid. The reaction products calcium carbonate and ammonium sulphate are separated from each other. The ammonium sulphate is withdrawn from the unit, while the calcium carbonate is directly returned to the flue gas desulphurisation unit. The ammonia, ammonium carbonate or ammonium bicarbonate required for treating the calcium sulphate is obtained at least in part from the gas purification of a coking plant.

Title: Digital triggering apparatus for pulse-controlled invertors
Inventor: WOLLSCHLAEGER KLAUS
IPC: H02M7/529
Filed: 1982-09-08
Abstract: The application according to the Main Patent VPA 82 P 3198 DE relates to a digital triggering apparatus for a pulse-controlled invertor. Using a microprocessor (4), the pulse-width modulation of each phase (R, Y, B) is determined from the condition that the product of the pulse width ( DELTA tR) and the DC voltage (Ugl) at the input of the pulse-controlled invertor (2) is proportional to the product of a predetermined reference voltage (Usin wtx) at the sampling time, and the sampling interval (T). According to the supplement proposed here, the calculated control signals (tR, tY, tB) are made to act symmetrically with respect to the centre of the sampling interval (T), in order to reduce harmonics. <IMAGE>

Patent DE-3246091-A1 (DE)
Title: Combined resist/discharge printing process
Inventor: ONG SIEN LING DR
IPC: D06P5/15
Filed: 1982-12-13
Abstract: In the production of discharge-dyed polyester articles using alkali-dischargeable disperse dyes, the white or coloured patterning effects thus to be produced are enhanced by bringing about an additional resist action by adding to the acidic dye preparation for the ground colouring (expediently in the last step), for example, zinc or aluminium salts which on contact with the alkaline discharge paste of the print patternings (expediently in the first step) also additionally cause, as a result of gel formation by the hydroxides formed in this case, resist effects at these sites. The formation of the desired resist effects is additionally assisted if the printing ink containing the discharge agent also contains in addition to or instead of the conventional alkalis, for example, alkali metal zincates or alkali metal aluminates, from which under the influence of the pH conditions of the ground colouring effective at the overlap sites, gels likewise form which for their part contribute to the patterning.

Patent DE-3310749-A1 (DE)
Title: Synchroniser for a countershaft transmission
Inventor: KAWAGUCHI AKIO
IPC: F16D23/06
Filed: 1983-03-24
Abstract: A radially extending collar is formed integrally on the synchronising sleeve of a ''Warner''-type synchroniser in order to limit the movement of either spring-loaded inserts or a one-piece leaf spring in a direction away from the individual gearwheel with which the synchroniser is to interact. This simplifies both the construction of the synchroniser and the assembly of the transmission of which the synchroniser is a part, and the use of standard gear-change sleeves and of standard taper-ring components is made possible.

Patent DE-3334494-A1 (DE)
Inventor: FAZEKAS PETER DIPL ING
IPC: G01R31/28
Filed: 1983-09-23
Abstract: A method for measuring a low-frequency signal progression at a measuring point of a specimen by use of an electron probe. A load on the circuit is kept as low as possible by employing a pulsed electron probe during a search of the measuring points. The pulsed electron probe may also be employed for actual measurement. By providing a pulse repitition frequency of the electron probe which is independant of the operating frequency of the circuit specimen, a phase shift of the primary electron pulses relative to the low-frequency signal progression is not necessary for real time measurement of the low-frequency signal progression.

Patent DE-3337143-A1 (DE)
Title: Drive device
Inventor: HEINEMANN OTTO DIPL ING
IPC: F15B11/22
Filed: 1983-10-12
Abstract: In a drive arrangement the reciprocating movement of a driven machine part (1) is produced by means of pressure-medium-actuated cylinder-piston arrangements (3 to 6) which are alternately connected by way of pressure medium connections (19, 20) to a pressure medium feed and a pressure medium discharge. In this case at least four differential cylinder-piston arrangements (3 to 6) functioning in parallel in pairs are provided in such a way that for each two cylinders one piston surface with a circular cross section and one with an annular cross section are acted upon by the pressure medium whilst, since the counter surfaces are identical when the pistons are displaced, in the second pair of cylinders the pistons displace a precisely equal quantity of pressure medium as in the first pair of cylinders. In this way an exact parallel drive running in the same direction is created using simple, standard differential cylinder-piston arrangements. <IMAGE>
Patent DE-3337223-A1 (DE)
Title: Highly brominated polystyrenes, process for their preparation, and their use
Inventor: JENKNER HERBERT DR
IPC: C07C17/12
Filed: 1983-10-13
Abstract: Highly brominated polystyrenes are prepared by reacting phenylethyl bromide with bromine in a solvent in the presence of a halogenation catalyst, subsequently eliminating hydrogen bromide from the bromination product using alkali, and subsequently polymerising the material. After the halogenation catalyst has been destroyed and the excess bromine has been removed, the solvent is removed by distillation from the reaction mixture in which the phenylethyl bromide has been reacted with bromine in a solvent. The distillation residue is taken up in an alcoholic solvent and reacted with aqueous alkali-metal hydroxide or carbonate solution. After the added water has been expelled and the polymerisation has subsequently been initiated catalystically, the resultant highly-brominated polystyrene is removed from the reaction mixture. In a preferred embodiment, this preparation process can be carried out within a single reaction vessel without isolation of the intermediates. The highly brominated polystyrenes are used as flameproofing agents for plastics.
