Patent DE-3164232-D1 (DE)
Title: Method and apparatus for heating organic waste by biological treatment
Inventor: MOILLIET GUY
IPC: C02F11/02
Filed: 1981-11-28
Granted: 1984-07-19
Abstract: Heat can be recovered by biological generation of heat upon aeration of refuse, such as garbage or sludge, in an aeration vessel (11) by introducing oxygen-containing gas, such as air, in a closed cycle (11, 33, 31, 35) to thereby enrich gas withdrawn from the vessel with the oxygen, typically by reintroduction of gas withdrawn from an upper gas portion (43) of the vessel, after introduction of additional oxygen, for example controlled by a valve (65) into a lower portion of the contents of the aeration chamber. Control can be effected automatically, by a control unit (55, 55') through a valve (51, 51') or manually; automatic control can be effected, for example, by sensing oxygen or carbon dioxide concentration by suitable sensors (57, 59) within the vessel. To permit recovery of methane of high quality in a subsequent decomposition and methane recovery container, material withdrawn from the aeration vessel is degassed in degassing chambers (68; 69, 70), for example by storage for about 1/2 hour, and venting of emanating gases. Control of valves regulating flow from, and to, the aerating vessel and the degassing chambers (69, 70) permits preheating of freshly introduced refuse by the material withdrawn from the degassing chambers in a counterflow heat exchanger (17'), while preventing possible escape of non-aerated substances from the vessel (11) by isolating the aeration vessel (11) during introduction of new refuse, and emptying only a chamber (e.g. 69) of said degassing chamber system (68).

Title: A process for preparing polyarylene polyethers
Inventor: SCHWAB THOMAS HARRY
IPC: C08G65/40
Filed: 1981-06-24
Granted: 1985-09-12
Abstract: Described herein is an improved process for preparing polyarylene polyethers by (a) converting a dihydric phenol to the alkali metal phenolate by adding an alkali metal or alkali metal compound to the phenol in a mixture of a sulfone or sulfoxide solvent and a solvent which forms an azeotrope with water, (b) removing water by codistillation with the azeotrope forming cosolvent, and (c) reacting the phenolate mixture with a dihalobenzeneoid compound, wherein a lighter colored product is obtained by adding the sulfone or sulfoxide solvent in increments. This may be accompanied by (1) adding an increment of the sulfone or sulfoxide solvent to a mixture of the dihydric phenol in the codistillation solvent and adding the remaining portion during the azeotroping step, or (2) adding an increment of the sulfone or sulfoxide solvent to the mixture of dihydric phenol and codistillation solvent and the remaining portion to the system simultaneously with the alkali metal hydroxide or other phenolate forming alkali metal source, or (3) adding a first increment of the sulfone or sulfoxide to the dihydric phenol-azeotrope forming solvent prior to step (a), a second increment simultaneously with the addition of alkali metal source in step (a), and the remainder during or at the end of azeotroping step (b).

Title: Producing power from a cryogenic liquid
Inventor: RUHEMANN MARTIN SIEGFRIED WILL
IPC: F01K25/10
Filed: 1981-06-18
Granted: 1985-10-17
Abstract: Power is produced from a methane-containing cryogenic liquid such as LNG by compressing the liquid and employing the compressed liquid as a refrigerant in the condensers of two closed and independent power cycles. The heat exchange medium in the first of the cycles evaporates in a lower temperature range than that at which the heat exchange medium in the second cycle condenses. The first heat exchange medium is condensed by heat exchange in a first heat exchange step with the compressed cryogenic liquid and the second heat exchange medium is condensed by heat exchange in a second heat exchange step with compressed cryogenic liquid recovered from the first heat exchange step and evaporating first heat exchange medium. Power is recovered from the expansion engines associated with the two power cycles.

IPC: F26B13/30
Filed: 1981-06-23
Granted: 1987-03-05
Abstract: Objects constituted by a porous web-like material, such as a paper web, a granular material, such as peat, or a solid material such as wood, are dried by placing the same in contiguity with a fine porous liquid suction surface which itself is in liquid communication with a liquid volume with the latter being in communication with apparatus by which the liquid in the liquid volume is maintained at an underpressure relative to the pressure of the liquid in the object to be dried so that liquid flows from the object into the fine porous suction surface. The liquid flow can be enhanced through the application of an over pressure or through the direction of radiation onto the object to be dried. In one embodiment, the fine porous liquid suction surface comprises the surface of a rotatably mounted cylinder whereby a web-like object, such as a paper web, can be dried as the same is carried on the cylinder surface.

Title: A gasification apparatus
Inventor: HELLESTAM CARL-JOHAN SIGVARD
IPC: C10J3/52
Filed: 1982-05-25
Granted: 1985-09-12
Abstract: In the manufacture of fuel gas or synthesis gas by partially combusting carbonaceous fuel, preferably solid carbonaceous fuel having a high content of non-combustible constituents, finely divided fuel is injected into a shaft-like reactor chamber (10) and is combusted partially while moving down through the reactor chamber, to form a fuel gas or synthesis gas which is removed from the reactor chamber at the upper part (12) thereof, while simultaneously melting non-combustible constituents of the fuel, the resultant melt being taken out of the reactor chamber at the bottom part (13) thereof. A layer (32) of molten material which covers the wall (11) of the reactor chamber and moves downwardly along the wall is sustained by maintaining a selected temperature for substantially instantaneous melting of the non-combustible constituents of the fuel, and by selecting the directions in which the fuel is injected into the reactor chamber so that at least a substantial part of the fuel or the non-combustible constituents contained therein is brought into contact with the wall (11) of the reactor chamber or the layer (32) on said wall during movement down through the shaft. The wall of the reactor chamber is kept cooled in order to maintain thereon, between the wall and the molten layer (32), a frozen coating (33) formed by the non-combustible constituents of the fuel and protecting against slag attack and overheating.

Title: Switching fiber optic amplifier
Inventor: SHAW HERBERT JOHN
IPC: G02F1/39
Filed: 1984-09-04
Granted: 1987-12-23
Abstract: A fiber optic amplifier utilizes a crystal fiber of laser material to bidirectionally amplify light signals. This amplifier permits the application of both pumping illumination and the signal to be amplified to the end of the crystal fiber to avoid the disadvantages inherent in side pumping this fiber. End pumping is accomplished by taking advantage of the slow spontaneous fluorescence of the laser crystal to sequentially apply the pumping illumination and then the signal to be amplified to the crystal. This sequential application of signals is made possible through the use of a switchable coupler which allows light to be selectively coupled from either of a pair of input optical fibers to a single output optical fiber which is coupled to the crystal fiber. The pumping illumination is initially supplied to the crystal fiber to invert the ions within the crystal. Once these ions are inverted, the coupler is switched to permit the application of the signal to be amplified to the crystal, and the application of pumping illumination is temporarily discontinued. The signal to be amplified propagates through the crystal to stimulate emission of coherent light from the laser material resulting in amplification of the signal. When this amplification process is complete, pumping illumination is again applied through the switch to the crystal fiber.
