Patent DE-3600056-A1 (DE)
Title: Fundamental voice frequency analyser
Inventor: ARNOLD KURT DR ING
IPC: G10L25/90
Filed: 1986-01-03
Abstract: The fundamental voice frequency analyser described hereinafter enables the pitch (fundamental voice frequency) in voice signals in the range of from 50 to 450 Hz to be determined with little circuit expenditure. The analysis occurs in real time almost without errors, especially also during the transient phase. Reducing the voice signal data down to features specific to the fundamental voice frequency allows the efficient analysis algorithm to be implemented in a conventional 8-bit microprocessor system. The data reduction is essentially achieved by a simple filter bank followed by extreme-value and zero-crossing detectors and by setting the interruption mask of the subsequent interruption unit. The interruption mask itself is determined by the algorithm in dependence on the pitch of the fundamental voice frequency and set via the interruption unit.

Title: Light-emitting diode with integrated function-monitoring element
Inventor: NIEWERTH REINHARD DIPL ING
IPC: G08B29/10
Filed: 1986-09-05
Abstract: The light-emitting diode (2) and function-monitoring element (3) are situated in a common envelope (1). The function-monitoring element is designed so that it responds solely to radiation in the range of the upper or lower spectral range of the radiation emitted by the light-emitting diode. The common envelope of the light-emitting diode and the function-monitoring element has an optical filter (4) at least in the vicinity of the light exit opening. The optical filter (4) is transparent in the region of the lower or upper spectral range of the radiation emitted by the light-emitting diode. The sensitivity range of the function-monitoring element (3) and the transmission range of the optical filter (4) are chosen so that they do not overlap. The optical filter ensures that only that radiation can enter the housing from the outside to which the function-monitoring element is insensitive. <IMAGE>

Title: Floor-mounted door closer for door wings held pivotably on the door frame by means of hinges
IPC: E05F3/22
Filed: 1986-11-28
Abstract: The door closers used in doors held on hinges are connected to the door wing by means of a pivoting arm connected to their closure shaft, via a sliding block which engages into a guide rail fixed to the door wing. However, in this design, the opening range of the door wing is limited, especially since the longitudinal centre of the closure shaft is not in line with the longitudinal centres of the hinges. There is now to be provided a new arrangement of the floor-mounted door closer, which, on the one hand, allows the door wing to be opened over the full opening range of approximately 180@ and which, on the other hand, keeps the door closer free of constraining forces in the event of assembly inaccuracies. The pivoting lever making the connection between the door closer on the one hand and the door wing on the other hand is fixed, by means of its connecting lug for the closure shaft, to the door wing approximately in alignment with the pivot pins of the hinges, the floor-mounted door closer being supported in the cement box centrically relative to the connecting lug so as to be pivotally movable and flexible. This arrangement makes it possible to open the door wing over approximately 180@ and allows a slight centre offset between the longitudinal centres of the hinges and the longitudinal centre of the closure shaft of the door closer.

Title: Combined-cycle turbine power station with fluidised-bed coal gasification
Inventor: MUKHERJEE DILIP DIPL ING DR
IPC: F02C3/28
Filed: 1986-12-13
Abstract: In a combined-cycle turbine power station, a fluidised-bed boiler (30) is connected to the coal gasifier (1); part of the fluidised-bed material from the gasifier (1) is extracted and burned in this boiler.

The rest of the steam comes from a boiler (15) that is heated by the hot combustion gases coming from the coal gasifier (1), or from a waste-heat boiler (26) heated by the exhaust gases from the gas turbine (23). A sulphur scrubbing vessel (9), which is provided with calcined desulphurising additives from a fluidised-bed furnace (10) heated by the combustion gases, is connected downstream of the coal gasifier (1). <IMAGE>
Patent DE-3644167-A1 (DE)
Title: Continuous process for the oxidative coupling of methane to higher hydrocarbons in the gas phase
Inventor: BAERNS MANFRED PROF DR
IPC: C07C2/82
Filed: 1986-12-23
Abstract: Continuous process for the reaction of methane or natural gas to give CnHm hydrocarbons (n >/= 2, m = 2n or 2n + 2), in particular ethane and ethylene. Ethane, ethylene and C3 and C4-hydrocarbons are obtained on the large scale by the processing of petroleum fractions in refining processes. The process proposed here makes possible the preparation of, in particular, C2 and C3-hydrocarbons of higher olefin content from natural gas, which is present in large amounts; natural gas thus represents an alternative to petroleum, which is restricted in its availability, for the production of higher hydrocarbons. Methane is reacted in the presence of oxygen or of another oxygen-producing gaseous oxidising agent at temperatures between 800 and 1250 K and at pressures between 2 and 100 bar, but preferably between 5 and 70 bar, in a chemical reactor through which the gas mixture flows. The ratio of the partial pressures of methane to oxygen is between 1:1 and 10:1, but preferably between 2:1 and 7:1. Preparation of higher hydrocarbons as chemical raw materials and starting substances for the production of liquid hydrocarbons. Figure 1 shows the temperature dependence of the product selectivities in the case of complete oxygen conversion (XO2 > 95%).

Abstract: Movable wall elements consisting of plastic:   - configured from a transparent composition, or coloured/transparent or coloured/opaque, - as solid individual panels, but also in open forms, such as in the form of grids or tubes, and other decorative versions, - as a wall which can be fully closed off as well as one with openings, whether these be hatches, doors or the like, closable or not, - optionally with lighting in the interior in the case of double-leaved wall configurations.   By virtue of the movable designs, the wall configurations can run in all conceivable directions. These configurations can be anything from walls which can turn off to those which run right round or they may be part-bent, part-straight walls or an S-shaped wall - every wish can now be fulfilled. There are many possible wall configurations, single-leaved, double-leaved (opened or filled) and as a solid or open wall (in the sense of being decorative).
