Title: Process for producing liquid pig iron in a smelting gasifier
IPC: C21B13/02
Filed: 1989-03-15
Abstract: In a process for producing liquid pig iron in a smelting reduction process using coal, the gasification of the coal being effected by means of oxygen in a smelting gasifier (1), the gas (6) drawn from the smelting gasifier (1), after cooling (7) if required and with the simultaneous generation of steam, is subjected to a compression (9). The compressed gas is then supplied, together with separately compressed air, to a furnace (10) and burnt under superatmospheric pressure, the off-gases (exhaust gases) of the furnace (10) being expanded via an expansion turbine (12) coupled to a generator (13). Preferably, in so doing, compressed air supplied or to be supplied to the furnace (10) is fed, at least in part, to a low-temperature air separation plant (21), the oxygen generated in the air separation plant (21) being introduced as gasifying oxygen into the smelting gasifier (1). <IMAGE>

Inventor: TSUJI KEIJI
IPC: G01B21/08
Filed: 1989-04-26
Abstract: An apparatus for detecting the thickness of sheets e.g. currency notes by detecting displacement of one (3) of a pair of rollers (2, 3) disposed so as to face each other across a transporting path of the sheets, the pair of rollers being driven by a driving motor, has the reference roller (2) rotatable about a fixed shaft (4) and the movable roller (3) abuttable against the reference roller (2) and rotatably mounted on a movable shaft (7) displaceable with respect to the reference roller (2). The apparatus further includes a timing signal generator for generating timing signals synchronized with rotation of the reference roller (2) and the movable roller (3), a displacement detector (10 - 15) for detecting the amount of displacement of the movable roller (3) by detecting the displacement of the movable shaft (7) in sychronism with the timing signals, a sheet detector (9) e.g. a photocell for detecting whether or not sheets are present at a zone where the reference roller (2) and the movable roller (3) face each other, a sheet thickness calculator for calculating the thickness of the sheet by deducting, in accordance with the timing signals, the amount of displacement of the movable roller (7) detected by the displacement detector when the sheet detector (9) does not detect any sheet at the said zone from the amount of displacement detected by the displacement detector when the sheet detector does detect a sheet at the zone. Accordingly it is possible to detect the thickness of sheets with high accuracy and this apparatus is particularly suitable for detecting double feed of notes and notes counterfeited by use of adhesive tape. <IMAGE>

Title: Flue gas purificn. - using carbon catalyst with ammonium sulphate coating
Inventor: DOEHL KLAUS WERNER
IPC: B01D53/86
Filed: 1989-05-11
Abstract: In chemical flue gas treatment with a carbon catalyst, esp. for NOx removal, by ammonia addn. to the flue gas stream at up to 200 deg.C, the novelty is that the catalyst is active coke which is subjected, prior to reaction with the flue gas, to an activation treatment with materials which at least form sulphuric acid and to a satn. treatment with a NH2 gp.-contg.  material in amt. sufficient for neutralising the sulphuric acid loading of the active coke. In appts. for carrying out the process, the flue gas is passed in countercurrent upwardly through a top-charged coke bed in a moving bed reactor in which (i) the top region (1) of the bed contains untreated coke which is fed with SO2 and any excess residual NH3; (ii) the next lower region (2) is injected with NH3 which opt. takes part in NO conversion; (iii) the next lower region (3) produces denitrogenation of the flue gas (8) with the SO2- and NH3-treated coke; and (iv) the coke is removed via a bottom outlet. ADVANTAGE - The process provides denitrogenation and desulphurisation of flue gas at low cost and low temp.
Patent DE-3919836-A1 (DE)
Inventor: REUMANN MANFRED
IPC: B21B41/10
Filed: 1989-06-17
Abstract: Method for cutting the leading turns and/or trailing turns of a wire coil in the course of spreading out rolling stock to be coiled, after the finishing group of a wire rolling mill to which a loop layer for the wire, a roller table, a main conveyor and a coil-accumulating mandrel are directly or indirectly connected. The wire is spread out in loops on the roller table. The loops are transferred to the main conveyor. Upon emergence from the loop layer of the leading turns and/or the trailing turns of a wire coil to be formed, the roller table is driven at a roller-table speed which is greater than the main-conveyor speed. As a result, the loops are deposited on the roller table with a cutting spread which is larger than the processing spread. The roller table is switched over to the main-conveyor speed as soon as or before the first of the loops laid out with a cutting spread reaches the main conveyor and the loops laid out with a cutting spread are transferred to the main conveyor. Cutting is carried out on the main conveyor in the region of the cutting spread of the loops while the subsequent loops are once more laid out on the roller table with the processing spread.

Title: Typewriter for typing secret information - has brush to make illegible letters typed on typewriter ribbon
Inventor: MENGEL HORST
IPC: B41J35/38
Filed: 1989-07-22
Abstract: The typewriter has a typewriter ribbon (17) which is unwound from a first spool (15) and after passing between the typing head (29( and the paper (1) is wound onto a second spool (25). The typed text can be read on the used ribbon by unwinding the ribbon from the second spool (25). To prevent unauthorised persons from finding out what has been typed, the ribbon (17) is passed over a brush (33) which makes the letters unreadable. The ribbon is pressed against the brush (33) by a guide block (35). USE - Typing information which has to be kept secret. Brush erases typed letters from used ribbon.

Title: Testing microcomputer-controlled assemblies and equipment - using comparison of fixed signatures with corrected signatures selected from series of parallel data vectors
Inventor: STOPP ANDREAS DR ING
IPC: G06F11/277
Filed: 1989-09-11
Abstract: A series of parallel data vectors selected using control signals or combinations of control signals is compressed between a start and stop instruction to form a signature. A corrected actual signature is generated from a real actual signature after the stop instruction using a correction vector of a correction instruction. The correction instruction corresponds to the equation system of a parallel, fully controlled and observable linear feedback shift register. The corrected actual signature is compared with a desired signature to enable a good-bad decision to be made. ADVANTAGE - High probability of error detection at low circuit cost or at defined cost. Enables self-testing, ensures maximal clock frequency and is universally applicable.

Title: Procedure for the operation of a waste material tip - the tip is constructed so as to exclude environmental air and water, and liquid and air are added in a controlled manner
IPC: F24D15/04
Filed: 1990-03-01
Abstract: The uncontrolled entrance of water e.g. ground water, surface water and atmospheric moisture, into the tip (5) is prevented from the start of the operation, such as for a roof or cover. The uncontrolled access of air to the tip is prevented as far as possible by applying a covering layer (6) at an early time. Liq. treat (7) of the tip are built in at different level in the tip and are used to assist the full decomposition of the decomposable matter in the tip material. The tip material may be treated with water while oxygen is excluded, so that the material decomposes anaerobically and with the maximum recovery of usable gas. (3pp Dwg.No.1)

Inventor: KRAUS UWE DIPL ING DR
IPC: H04N11/00
Filed: 1990-08-28
Abstract: In letterbox colour television systems, additional data must be transmitted in the most compatible possible manner. However, additional crosstalk effects and, in known television receivers, synchronization disturbances can occur. If the additional data in the letterbox strips are transmitted only in the form of a squared modulations of the chrominance carrier, crosstalk effects are prevented and no synchronization disturbances occur in known television receivers. If both phase relations of the square-modulated chrominance carrier are constant, i.e., neither of the phase relations is switched with alternate lines, the vertical frequency resolution of the additional data can be advantageously doubled. If the phases of the additional data (Z1, Z2) are additionally rotated through 45 or 225 degrees, the crosstalk effects are further reduced. 16:9 letterbox television receivers.
