Patent DE-2633491-A1 (DE)
Title: Gasifying coal to carbon monoxide and hydrogen - by crushing, burning coal fines and using combustion gases in gasification zone
Inventor: MATTHEWS CHARLES WILLIAM
IPC: C10J3/54
Filed: 1976-07-26
Abstract: In gasification of coal to produce CO and H2 (A) coal is crushed, then elutriated to separate coal fines and coarse particles, (b) the fines are scrubbed with water to form a slurry, (c) a 1st stream of coal, consisting at least partly of the slurry, is burned without bed formation in presence of water under oxidn. conditions, to produce gases contg. CO2 and steam, and (d) a 2nd stream of coal, consisting at least partly of the coarse particles from (a), is fluidised in a separate zone by the CO2 and steam from the combustion zone, to produce CO and H2. The CO + H2 may be used as fuel, as reducing gas in metallurgy or chemical processes for conversion to H2, in petroleum refineries and in coal conversion plants. There is little pollution and no water effluent is product. The water used may be polluted water from other processes. Ash is removed in oxidised from as solidified slag, suitable for landfil or mineral recovery. Gaseous impurities are destroyed in the process, or converted to useful forms, e.g. S cpds. are converted to H2S, from which S can be recovered; N cpds. are converted to NH3, which is recovered, or to N2. The process is economical in use of heat. High-S, high-ash by-prods. or wastes from other processes, e.g. from a solvent coal liquefaction can be used as raw material. The operation is safe, since there is a fluidised bed of coal char between the O2 injection zone and the combustible gas.

Title: Hydraulically pressurised tunnel lining - is circular resilient element with pressure applied at sides enabling top to resist roof pressure
Inventor: EDELING HELMUT DIPL ING
IPC: E21D11/00
Filed: 1976-12-16
Abstract: A tunnel lining consists of a resilient element which is circular to match the shape of the tunnel, with pockets (7) along two diametrically opposite sides, which can be filled with water under pressure from a storage tank above ground. The pressure maintained is sufficient to cause the top and bottom portions to resist the downward pressure on the tunnel roof.

Title: Vulcanisation mandrel for mfr. of curved tube fittings - is fitted with slidable calibrating sleeves, one of which is fixable in vulcanisation position
Inventor: RASTAEDTER KARL DIPL ING DR
IPC: B29C53/08

This latter bushing is pref. accurately fixable in its vulcanisation position. The bushings serve as calibrating sleeves and are selectively movable so that an unvulcanised elbow hose that is inaccurate to size can be rendered dimensionally accurate.

Title: Mixing metered additive into polymer - in which impulses to preselector switches automatically provide required proportions in set unit quantities
Inventor: MUECKE WALTER ING GRAD
IPC: G05D11/13
Filed: 1977-08-23
Abstract: An additive is mixed into a granulate/powder by equipment with its mixing chamber fitted at its outlet with a device to electrically signal according to required quantity of material. The chamber has a top inlet for the main material and a metering device for set doses of additive in numbers of unit quantites. A controller has a first preselector switch for the number of signals to the metering device and a second switch to combine a set number of unit quantities. The controller has an impulse generator sending impulses at set intervals to a third preselector switch to divide the dose into a selected number of equal units, this number being determined by the second switch. Simple design, suitable for complicated proportions of additive and granular additives, avoids problems of the size of mixing chamber used, suitable for e.g. pigmenting polymers i.e. fitting to the inlet of e.g. extruders.
Patent DE-2740841-A1 (DE)
Title: Countercurrent prodn. of steel - by flowing crude iron down shaft up which oxygen (carriers) and slag formers are blown
Inventor: FRANKE ERNST PETER PROF DIPL I
IPC: C21C5/56
Filed: 1977-09-10
Abstract: Steel is made continuously by an entirely counter-current principle, where crude iron flows as droplets vertically down a shaft (a). Distributed over the entire base (b) of shaft (a) are tuyeres via which O2, O2-carriers, and slag formers, are blown at low pressure to form an FeO slag rich in CaO, which travels vertically upwards without over-heating. The Fe droplets are initially dephosphorised and decarburised as they fall through the slag, whereas the final removal of P and C occurs by reaction with the fresh slag near base (b), near which is a taphole for molten iron. CO2 and possible carbonates are added near base (b) for cooling the slag to the desired temp.; and an upper outlet is used to siphon off the slag. No red-brown smoke is formed by the process due to the low pressure.
Patent DE-2746325-A1 (DE)
Title: Sulphuric acid mfr. from sulphur di:oxide at elevated pressure - by catalytic oxidn., absorption and recirculation of non-oxidised gas using simple plant
Inventor: MUCHLENOV IVAN PETROVITSCH
IPC: C01B17/765
Filed: 1977-10-14
Abstract: In H2SO4 mfr. by catalytic oxidn. of SO2 with O2, recovery of the SO3 from the gas mixt. and recirculation of the unoxidised SO2 to the oxidn. stage, the process is carried out at a pressure of 2-20 (pref. 5-12) atmos. The process avoids the need for the complex construction of 4-stage contact appts., intensifies prodn. and permits the utilisation of large amts. of heat for high energy steam generation. No gas purificn. and drying stage is necessary. The use of a fluidised bed in the combustion of S vapour and oxidn. of SO2 and an immersion heat exchanger simplifies the construction of the plant and eliminates the gas heat exchanger.
Patent DE-2754531-A1 (DE)
Title: Safety handlebar for bicycle or moped - has shock absorbing foam layer covering concealing sharp edges and twist-grips for operating brakes
Inventor: HOFMANN-IGL ERNEST
IPC: B62K21/12
Filed: 1977-12-07
Abstract: The handlebars of a two wheeled vehicle are covered with a thick layer of foam material. The crossbar (3) is attached to the vertical steering pillar (1) by a spacer block which projects forwards so that the ball (9) can be built into the assembly without any projecting parts and also enclosed by the foam material. The nut on top of the steering pillar and the nut securing the crossbar are also embedded in foam. The lever (11) for ringing the ball can also be similarly embedded. The layer is intended as a protection against injury, since no parts are allowed to project and thus form a source of injury in the event of a collision. The layer also acts as a vibration absorber, and a protection against cold, since no metal parts contact the hands of the cyclist.
Patent DE-2755312-A1 (DE)
Title: Paper web edge drying device - has HF electrodes arranged along and adjacent marginal edges to assist drying web extending along whole width of drying drum
Inventor: BRUENING HELMUT DIPL ING
IPC: D21F5/16
Filed: 1977-12-12
Abstract: Device for capacitive drying of edges of a dielectric material, such as a paper web, has pairs of electrodes mounted adjacent and along each longitudinal marginal edge of the paper web, the electrodes being staggered alternately and connected to a source of high frequency. The length of the electrodes is small in comparison with approx. 1/5 of the wave length of the source and cover only teh marginal edges. Source is controlled by a pair of sensors which measure the moisture content at the marginal edge adn the centre of the web. Used for drying paper webs which extend over the whole width of a drying cylinder. Ends of drying cylinder have lower temp. and the lack of heat is compensated by the high frequency edge heating. Since the length of the electrodes is comparatively small flashover danger along the electrodes is min.

Title: Heatable railway points temp. sensors - are axially movable in cable shoe and use plug seating, without screw head
Inventor: KALBHEIM PAUL DIETER
IPC: E01B7/24

Abstract: The cable shoe is attached to points or to a rail component, and provides detachable accommodation for a temp. sensor connected to an underground cable leading a distributor for assessing the temp. of heatable railway junction points or other pieces of rail susceptible to temp. effects. The sensor(3), without a screw thread or screw head, is held so as to be axially displaceable in the cable shoe (2) and in its plug seating. It may be secured on the shoe by a clamping nut(5), in the form of a fully enclosing housing unit. The shoe's plug piece(6) can be monolithically formed with its fixing foot(7) on the points. This permits rapid exposure of the sensor for maintenance or replacement.
