Patent DE-3633690-A1 (DE)
Title: Process and apparatus for removing acidic gases, such as SO2, SO3, H2S, CO2 and/or COS, from hot gas mixtures
Inventor: SPORER JOSEF DIPL ING
IPC: B01D53/14
Filed: 1986-10-03
Abstract: A process is described for removing acidic gases, such as SO2, SO3, H2S, CO2 and/or COS, from hot gas mixtures. In this case, the gas mixture is cooled by heat exchangers and then, for absorption of the acid gases, is fed to scrubbing with a solvent. After the acid gases have been absorbed, the solvent is regenerated and returned to the scrubbing. In order to decouple the greatest possible amount of energy, it is proposed to cool the hot gas mixture to a temperature beneath the dew point and to use at least some of the energy released in this for regenerating the solvent. In this manner, the process according to the invention is independent of other energy sources and, moreover, further permits the generation of usable heat. <IMAGE>

Title: Method for the separation (removal) of solids from suspensions and centrifuge decanter for carrying out the method
Inventor: ZEITSCH KARL DR ING
IPC: B04B1/20
Filed: 1986-11-13
Abstract: In the separation (removal) of solids from suspensions in centrifuge decanters by means of sedimentation, it is proposed that the feed flow be directed below the level of the liquid as far as the drum wall of the centrifuge decanter. This is realised by means of a centrifuge decanter with an axial feedpipe and a discharge worm, the discharge worm having radial bores which are connected to a feed pipe which is integrated and therefore involved in rotation, and the said radial bores ending directly ahead of the drum wall.

Title: Breastwork duct with a cover
Inventor: JORDAN ERNST-GUENTHER ING GRAD
IPC: F16M11/14
Filed: 1986-12-19
Abstract: In the case of a breastwork duct having covers which are held one behind the other in the longitudinal extent of said duct and such that they can be displaced longitudinally, which covers are used for closing the breastwork duct which is profiled in the form of a groove and is open at the front, the covers can either abut against one another or can be arranged at a distance from one another to form an apparatus opening. In order to simplify the production of apparatus openings of virtually any desired shape and size, it is proposed to insert a cover section of the same width as the covers between two covers (2) which are arranged at a distance from one another, which cover section can in each case be assembled from two first elongated parts (5), which are identical to one another in mirror image form and can be arranged at right angles to the longitudinal extent of the breastwork duct, and from at least one second part (6) which can be inserted between the latter parts (5) at the same level, the second part (6) being used to form an apparatus opening and furthermore having a width corresponding to a grid size, and the first parts (5) having edge parts which cover the adjacent covers (2). <IMAGE>

Title: Electrically conductive polymer containing ferrocene units
Inventor: HERRMANN WOLFGANG A PROF DIPL
IPC: C08G61/12
Filed: 1987-02-07
Abstract: An organometallic electrode material which can be used for rechargeable polymer batteries can be obtained by double thiophene substitution of ferrocene to give 1,1'-bis(2-thenyl)ferrocene of the formula <IMAGE> and subsequent intermolecular linking thereof by means of butyllithium and copper(II) chloride to give poly[1,1'-bis(2-thenyl)ferrocene]. This results in a poly-sandwich structure in which the redox activity of the metal centre and a good reversible oxidisability of the heterocycle bridges between the ferrocene units act synergistically. A reversible charging and discharge capacity of 50 Ah/kg could be measured on an electrical test cell equipped with the polymer material.

Title: Non-reversible engine
Inventor: GROZA IGOR
IPC: F01C1/356
Filed: 1987-03-16
Abstract: For eliminating the reversibility of the engine a piston movement on a circular orbit is used so that a reciprocating movement of the piston is dispensed with. For this purpose, the cylinder is formed from two walls movable relative to one another, one of which is rigidly connected to the piston. In order to obtain the moving force, the chamber of the cylinder is divided by an additional descending wall synchronised with the piston rotation.

IPC: C23C16/511
Filed: 1987-08-12
Abstract: A method of depositing a thin film on the surface of a substrate using a microwave plasma assisted chemical deposition technique consists in directing the gaseous reaction mixture towards the surface through a multiplicity of perforations in a plate spaced from and substantially parallel to the surface while a microwave plasma is produced between the plate and substrate, so as to cause a chemical reaction to take place and form said film on the surface. The substrate may be silica and glass may be deposited on the substrate as a first film in a desired pattern, eg by selective removal of part of the film after deposition to leave the pattern remaining, and a second film of glass, having a lower refractive index, is subsequently deposited on the first film. Metal and silica (doped with undoped) films may also be deposited. The method is intended primarily for depositing thin optical waveguiding films for use in integrated optics but other applications such as in semiconductors and integrated circuits are evisaged. Apparatus for depositing films as illustrated in Fig. 2 consists of a silica outer tube 4, a silica inner tube 2 having an external diameter slightly less than the internal diameter of a main portion of the outer tube, the inner tube being closed at one end by a silica plate 6, on which the substrate is placed, a dispenser tube in the shape of a funnel closed at its wider end by a perforated disc 7 and terminating at the opposite end in a narrow inlet portion 8 having an external diameter which is smaller than the internal diameter of a neck portion 5 of the outer tube and an O- ring vacuum seal 12 formed between the inner tube 2 and the main portion 4 of the outer tube 1. <IMAGE>

Title: Washing machine or washer drier with a lye pump and lint filter
Inventor: EWERT ANDREAS
IPC: D06F39/10
Filed: 1987-09-18
Abstract: Washing machine or washer drier with a lye pump and lint filter. Lint filter devices are known in run-off systems of automatic washing machines and occasionally have to be removed for cleaning purposes. When the filter housing is opened, residual water remaining in the run-off system can flow out of the housing of the machine, and this has an adverse effect in the case of washing machines integrated in kitchen lines. The design according to the invention of the lint filter and of the filter housing is to prevent the residual water from flowing out of the appliance. In order to prevent the water from flowing out of the appliance, when the filter insert (3) is removed a blocking insert (2) closes the inflow connection (4) and the delivery connection (5) of the lye-pump unit. The blocking insert (2) is pressed into its closing position when the removal handle (9) for the filter insert (3) is actuated. Washing machines with a lint filter designed according to the invention are especially suitable for installation in kitchen lines. <IMAGE>

Abstract: In the case of an optical pick-up for CD players, the track error signal TE is, for example, obtained from the difference between two photoelectric voltages ES and FS. If, for example due to mechanical impact on the CD player, the light beam jumps from the data track to be picked up, it can be directed back onto the correct data track by means of information contained in the subcode, which however impairs the sound reproduction. In the case of unformatted optical recording media, however, this possibility of correction does not exist. 
<??>In order to direct a laser beam (8) which has jumped from the data track to be picked up back to this data track accurately and quickly, it is established by means of a direction logic (5) and a forward- backward counter (6) by how many tracks the light beam (8) has deviated to the right or left from the data track to be picked up. The correction signal for the tracking control circuit is obtained from the counter reading.
