Title: Mono:methyl-hydrazine in aq. soln. - by reaction of chloramine and methylamine in presence of base, with extra heating stage to remove dangerous by-prods. before work-up
Inventor: LECOLIER SERGE
IPC: C07C241/02
Filed: 1990-09-13
Abstract: Prodn. of monomethylhydrazine (I) in aq. soln. comprises reaction of chloramine (II) with a 1 mol excess of MeNH2 (III) for a time D1 in aq. medium and oxygen-free atmos., in the presence of a strong base, pref. NaOH, and working up the mixt. of (I) and volatile by-prods. obtd., pref. by stripping followed by distn., to give a conc. aq. soln. of (I). The novelty is that, before the reaction mixt. is worked up, it is then heated to 30-100 (pref. 70-100) deg.C for a time D2 such that D2/D1 is greater than 10 (pref. 50-100), in the absence of oxygen and keeping the pH above 13.5, so that the above by-prods. (esp. methyldiazine) are partly or completely removed. - Process is operated continuously; (II) is produced in aq. basic medium with pH 10-14 (pref. in a NH3/NH4Cl buffer) under oxygen-free atmos., by reaction of ammonia with alkali hypochlorite (pref. NaOCl) at -10 to +10 deg.C. (II) is produced in a first reactor with an inlet for the aq. medium and the reactants and an outlet through which the reaction mixt. is transferred by suitable devices to a sec. reactor, from there to a third reactor in which the extra prodn. stage is carried out, and then to the purificn./concn. stage. The third reactor is a tube reactor fitted with a double mantle which enables circulation of a fluid. On leaving the first reactor, the medium contg. (II) is passed to a mixer which is also charged with (III), and the mixt. thus obtd. is transferred to the sec. reactor which is charged with strong base.

Title: Sensor for thermal radiation emitting material - contains several detectors and plausibility evaluation circuit, e.g. in rolling mills
Inventor: WEBER GUENTHER
IPC: G01J5/00
Filed: 1990-12-03

Title: Coal treatment comprising pyrolysis to semi-coke - and gasification in suspension, with removal of ash and recycling of gaseous prod. to pyrolysis zone
Inventor: ALLAN PETER
IPC: C10J3/66
Filed: 1991-02-20
Abstract: In treatment of coal, (a) particulate coal is pyrolysed in a pyrolysis zone, (b) the pyrolysed coal, i.e. semi-coke or low-temp. coke is fed into a gasification zone, with a gaseous medium, (c) the coal is held in suspension in the gasification medium and is gasified, with formation of a hot, gaseous prod.  fraction and ash, using an adequate amt. of the medium, and a coal particle size such that the pyrolysed coal can be suspended in the medium, (d) the ash is removed, (e) the hot, gaseous prod. fraction is fed into the pyrolysis zone, so that pyrolysis of the coal is caused (partly) by this prod. fraction, and (f) a gaseous prod. stream, contg. gaseous prods. from the gasification zone and volatile components expelled from the coal in the pyrolysis zone, is withdrawn. ADVANTAGE - Max. value is obtd. from the volatile coal components; good yields of high quality coal tar are obtd.; there is no intermediate cooling between pyrolysis and gasification zones, so that O2 consumption is reduced; the heat content of the gases leaving the gasification zone is utilised in direct heating and pyrolysis of the coal, without additional units, e.g. a heat-exchanger; a hopper is not needed between these zones: the atmos. in the pyrolysis zone contains some H2, giving the advantages of hydrogenative pyrolysis without a separate H2 source; the residence time of the semi-coke in the pyrolysis zone is only a few secs., avoiding or reducing cracking of the tars; excessive recycling of semi-coke to the pyrolysis zone is avoided; the heating rate of the semi-coke in the gasification zone is high; the appts. is simple and a separate quenching of the prod. gas is not needed; feeding the coal as a slurry avoids the need for a hopper; the slurry may be in a contaminated condensate, avoiding the cost of purifiying the condensate.

Title: Circulation de-gassing of steel for metallurgical industry - by adding alloying material added in the form of discrete portions
Inventor: STEIER EDGAR
IPC: C21C7/10
Filed: 1991-05-04
Abstract: The process is characterised by the fact that alloying materials are adding in the form of discrete portions. The installation for carrying out the method includes a vacuum lock consisting of a collecting hopper and a container with an outlet pipe allowing it to be isolated from the hopper and the pipe. Alternatively, the installation is characterised by a vacuum container for reception of alloying materials. This container can be isolated from the vacuum chamber. The devices for isolating the container are bell closures with sealing elements capable of being raised and lowered. Such bell closures are connected with the piston rods of actuating pneumatic cylinders. At least the lower bell closure and its cylinder rod are lined outside with wear resistant materials. Similarly, the vacuum container for reception of alloying materials (metioned under the alternative characterisation of the installation) is provided with a wear resistant liner. USE/ADVANTAGE - Used in the metallurgical industry. It allows present complicated installations to be replaced by simpler, less costly equipment requiring less space. The operation of the plant, in comparison with the existing procedures, is also simplified.

Abstract: A memory unit (SE) having a plurality of "address areas" which can be freely varied in size and number is specified. Only one address value is ever stored for an address area, along with the start address and end address. An address generator (AG) counts through the addresses from the start address to the end address. The start and end addresses are fed to an address register (AR) via a central computer (ZR), which is connected to an address generator (AG). The start and end addresses in the address register (AR) and a current address value in the address generator (AG) are called up by using a code number. The address generator (AG) counts through the address area until the end address is reached. The memory unit (SE) is used preferably in a cross connect of an SDH (synchronous digital hierarchy) transmission system. <IMAGE>
