Patent EP-0286115-A1 (EP)
Inventor: JOHANSEN KJELD
IPC: C12P5/02
Filed: 1988-04-08
Abstract: In a method for making biogas from liquid manure or the like, in which fatty acids or compounds or derivatives thereof are used as accelerator for the process, the new feature is that an additive for the process liquid is used consisting of bentonite or the like having previously been used for purifying edible oils or fats, for which reason they contain fatty acids and the like in an adsorbed condition. 
     The new method makes it possible to avoid the risk of an excessive concentration of fatty acids, at the same time as the used bentonite, which up to the present has been difficult to dispose of, may be used for a useful purpose.

Title: Optische Steuervorrichtung zum Steuern der in einem optischen Wellenleiter geführten Strahlung, insbesondere optische Schalter
Inventor: AURACHER FRANZ DR DIPL-PHYS
IPC: G02F1/1506
Filed: 1982-08-13
Abstract: Es werden optische Ein-/Ausschalter bzw. Umschalter mit Glasfasern beschrieben, bei denen eine mechanische Beanspruchung der Faser vermieden wird, und die weitgehend in Planartechnik hergestellt werden können. Der Schaltvorgang wird durch Verschieben eines Flüssigkeitstropfens in einem Spalt zwischen fluchtenden Glasfasern erreicht, der wahlweise durch elektrische, magnetische oder mechanische Kräfte in den Spalt bewegt wird. Bei einem Umschalter wird das Licht durch eine immertierende Flüssigkeit in der durchgehenden Faserstrecke geführt bzw. ohne Immersion in die abzweigende Faser reflektiert. Die Umschaltung zwischen Transmission und Reflexion kann auch durch zwei nicht mischbare Flüssigkeiten mit unterschiedlichem Brechungsindex erfolgen. Der Schaltvorgang kann auch durch ein Medium erreicht werden, das auf elektrochemischem Wege im Spalt erzeugt wird, oder zum Verschwinden gebracht wird, oder auch durch ein Medium, dessen optisches Transmissionsverhalten elektrisch magnetisch oder thermisch gesteuert werden kann. Die Schalter haben den Vorteil, daß mechanische Beanspruchungen der Faser weitgehend vermieden sind und daß sie in Planartechnik herstellbar sind, wodurch ganze Schalterzeilen ohne größeren Mehraufwand realisierbar sind.

Abstract: In the process, semiconductor wafers (1) made of, for example, GaAs are annealed in a reaction tube (1) under a protective gas atmosphere consisting of, for example, a mixture of N2 and AsH3. For this purpose, the reaction tube (2) is first heated to a base temperature at which the annealing process does not yet proceed and at which no wall coatings occur. In the case of semiconductor wafers (1) composed of compound semiconductors such as GaAs, the protective gas contains a compound of the more readily volatile element, for example AsH3, which decomposes at the base temperature and produces an overpressure of the more readily volatile element. The semiconductor wafer (1) is heated by a selective heater (4), for example a lamp (14), to the annealing temperature and is exposed to the annealing temperature for 5 to 20 sec.

Abstract: The arrangement according to the invention is intended for separately sensing the power consumption of both user groups in systems in which the second user group (4) is only operated during a first tariff phase, and it is to be made possible to check the two two-tariff meters with respect to one another. This object is achieved by the fact that the first user group (3) is connected via the series circuit of both two-tariff meters (1, 2) and the second user group (4) is only connected via one two-tariff meter (1) to the electricity supply network and that a functional check of the two two-tariff meters is carried out by comparing the counts of the two two-tariff meters and the power consumption of the two user groups (3, 4) is separately sensed by adding or, respectively, subtracting the counts. The arrangement is particularly suitable when a Ferraris meter is combined with an electronic electricity meter. <IMAGE>

Abstract: This multifunctional sun bed or the like is characterised by end rest surfaces (7, 8) rotatable through variable angles by stable-­positioning articulated joints (11, 11B). 
     Said articulated joints (11, 11B) can be different according to whether they are to be operated not only directly, but also indirectly by cable. 
     Said directly operated joints are characterised by two wheels (35, 37; 36, 38) with conjugate flat toothing engaged with each other by the action of a cam (41; 45, 46) which overcomes the separating action of an opposition spring (39, 40) acting between them. 
     Said indirectly operated joints are characterised by a toothed sector (12) bored (19) at its centre (16) to support a frame for a rotatable rest surface (7,8) having its end (7E, 8E) provided with a pair of teeth (20A, 20B) defining a cavity (21) coinciding with the cavities (15) of the toothed sector (12) during its angular travel, so that said cavity (15, 21) can receive a locking pin (22) for the two parts (7E, 12) which is mounted on a U-section (23) pivoted on said rest surface frame (7, 8) to enable required angular disengagement between the parts to be obtained with the aid of a cable (31).

Abstract: The invention relates to a process for crosslinking cationic lacquer binders, in particular cathodically depositable lacquers, using (poly)-2-hydroxyalkylurea compounds. …<??>The 2-hydroxyalkylureas are obtained by reacting organic di- or polyisocyanates with secondary  beta -hydroxyalkylamines. …<??>The claimed crosslinking agents make possible not only film formation in the baking range of about 140 DEG C, which is particularly favourable for water-borne paints, but also a more selective half- blocking owing to the difference in reactivity of the NCO groups of individual diisocyanates toward secondary amino groups, which is more pronounced compared with hydroxyl groups.

Abstract: A gas laser for producing laser oscillation by circulating a laser gas. The gas laser comprises a laser gas supply de­vice (5), a gas supply valve (6) provided at an outlet of the laser gas supply device, an exhaust device (9) for exhausting the laser gas in a discharge tube, a pressure sensor (7), a gas container exchange checking switch (5a) and a controller (10). The controller (10) closes the gas supply valve to exhaust the gas, opens the gas supply valve after the interior of the laser oscil­lator has been evacuated to introduce the laser gas into the laser oscillator, and closes the gas supply valve again to evacu­ate the interior of the laser oscillator. Therefore, the air that has flown into the conduit when the gas container is ex­changed is exhausted from the oscillator, so that the laser output will not decrease and will not lose stability.

Inventor: DOUTRE DON A
IPC: G01N33/20
Filed: 1989-11-14
Abstract: The invention provides a new method for the determination of the concentration of gas dissolved in a molten metal or metal matrix composite employing a new immersion head probe in apparatus employing the method. Such determinations are needed to facilitate removal of the gas, which can cause loss of desirable properties and/or bubbles in the solidified material and subsequent processing difficulties. This determination is particularly difficult with metals containing high concentrations of particulate additions, such as metal matrix composites, since it is necessary to avoid deposition of the particulates and consequent inaccurate readings. The method employs apparatus which circulates an inert carrier gas through the probe in gas exchange contact with the molten metal to entrain dissolved gas until an equilibrium mixture is obtained; the concentration of the dissolved gas in the mixture then is representative of its concentration in the molten metal. The head consists of a monolithic or integral body of a porous gas-permeable material of sufficient porosity, pore size and permeability to permit the necessary gas diffusion in a reasonable period of time. If the test is to be carried out in a stationary body of molten metal, the probe may be vibrated or the metal may be stirred.
