Title: Apparatuses for dry-steam refuse pyrolysis, residual degassing of the pyrolysis products and method for carrying out these processes
Inventor: SCHMIDT EDWIN
IPC: C10B7/10
Filed: 1994-08-20
Abstract: In pyrolysis processes for volume reduction the waste materials are heated in a low-oxygen atmosphere to, for example, 500 DEG C. Conventionally, this principally takes place in a rotating drum using pyrolysis gas atmosphere as heating medium. A disadvantage in this case is the low thermal capacity, thermal conductivity and heat transfer efficiency of this heating medium and its stationary contacting with the waste materials. In addition, critical substances are carried over into the subsequent high-temperature phase and pollute the excessively voluminous emissions of dusts and slag etc. According to the invention the heating medium used is superheated steam in rotating heating chambers, for example exhaust steam from a preceding application which is superheated in countercurrent heating.   Highly superheated steam has a gas character, a high thermal capacity and heat transfer efficiency and it is inert. Critical substances are separated out from the pyrolysis gas by condensation and also likewise from the pyrolysis products from which these are removed by suction in the gaseous state by vacuum effect. By this means, refuse coal cleaned of pollutants and substances generating these can be produced as a non-fossil energy source from house refuse (domestic waste), commercial and industrial wastes and from sewage sludge, biowastes and agricultural wastes.

Filed: 1994-12-19
Abstract: The proposal is for a circuit for detecting an overload in an adjusting drive (10, 11, 12) operated by an electric motor (10) with provision for detecting the current flowing through said electric motor (10). A motor current evaluator (29) supplies a characteristic (36) of the motor current which is compared by a characteristic comparator (37) with a predetermined limit characteristic (34) and emits a switching signal (39) depending on the result. The switching signal (39) is further transmitted in a release circuit (40) as an overload signal (41) if there is a release signal (35) which is established by a rotation speed comparator (33) from a comparison between the rotation speed occurring in the adjusting drive (10, 11, 12) and found from a detected rotation speed (28) and a limit characteristic. The circuit of the invention is particularly suitable for preventing overload on the electric motor (10).

Title: Device and method for automatically checking microprocessor-controlled electric apparatus, particularly in motor vehicles
Inventor: DENZ HELMUT
IPC: G01R31/28
Filed: 1982-07-15
Abstract: Method for automatically checking microprocessor-controlled electric apparatus (10) in motor vehicles, capable of performing predetermined functions with respect to preset emitting signals and memorize a data word corresponding to a detected fault. In order to signal the error, the data word is converted into a sequence of signals or into a voltage by measuring the voltage, preferably by installing a diagnostic intermediary plug (42) between the transmission wires and the electric apparatus (10). A voltmeter (47) displaying said sequence of signals or said voltage may be connected to that checking plug. To this effect, a predetermined voltage is affected to each predetermined type of fault. It is thus possible to give a diagnostic as complete as desired of a complex system by means of a simple voltmeter (47), commercially available.

Abstract: Une solution sert à faire gonfler des polymères formant des plaquettes de circuits imprimés avant que celles-ci ne soient soumises à une étape de gravure par alcalino-oxydation et à un nettoyage des passages perforés dans celle-ci. Un solvant organique est ajouté à une solution aqueuse afin de faire gonfler des polymères formant des plaquettes de circuits imprimés avant leur gravure par alcalino-oxydation. En tant que solvant organique, on ajoute à la solution un ester d'anhydre carbonique à chaîne droite ayant la formule générale R1-O-CO-O-R2. dans laquelle R1 et R2 désignent alkyle ayant 2 à 4 carbones, ou un ester d'anhydre carbonique cyclique, tel que le carbonate de propylène ou d'éthylène. Cette solution de gonflement permet de traiter les plaquettes à des températures moins élevées, évite la formation de poches et réduit les pertes par évaporation. L'invention est utile lors du nettoyage des passages percés dans des plaquettes de circuits imprimés en électrotechnique et en électronique.

Abstract: Un mécanisme manuel d'entraînement bidirectionnel sert à générer un mouvement de rotation et peut être utilisé de manière particulièrement avantageuse dans les systèmes d'ajustement des sièges de véhicules à moteur. Ce mécanisme se caractérise par une possibilité de réglage fin et par un fonctionnement silencieux. Le mécanisme comprend des zones élastiques (Fa, Fb) situées des deux côtés et hors du guidage de coulisse (K, Ka, Kb). Ces zones exercent sur les éléments d'encliquetage (3a, 3b) une force dirigée en sens opposé à la direction d'encliquetage des dents (30, 30', 50, 50'). Cette force élastique n'agit pas sur l'élément d'encliquetage (3a, 3b) sollicité dans la direction d'entraînement de façon à séparer les dents (30, 30', 50, 50'), alors qu'elle soulève des dents complémentaires (50, 50') l'élément d'encliquetage (3a, 3b) rappelé dans la direction de la position zéro. Dans un autre mode de réalisation, les éléments d'encliquetage (3a, 3b) s'engrènent avec les dents (50') d'une roue d'entraînement (5') à denture intérieure. Les éléments d'encliquetage (3a, 3b) sont montés sur un axe (31') du levier d'entraînement situé à l'intérieur de la denture intérieure (50').
