Patent EP-0515474-A1 (EP)
Title: method and apparatus for the purification of waste gases.
Inventor: KUIVALAINEN REIJO
IPC: B01D53/68
Filed: 1991-02-19
Abstract: An apparatus provides purification of waste gases by adding particles of reagent and/or absorbent, which react with the pollutants in the waste gases, to the gases, and by introducing the gases into a wetting reactor for activating the reagent or absorbent contained in the gases. Gases are conveyed to at least two levels in the reactor through inlets so that a first portion of the gases is introduced into a wetting zone and a second portion of the gases below the wetting zone. A high density of particles is maintained in the wetting zone by recycling to the wetting zone particles separated from the gas above the wetting zone.

Abstract: On décrit un procédé permettant l'épuration totale d'eaux lacustres par l'intermédiaire d'une simple opération de courte durée qui économise l'énergie et ne risque pas de provoquer des nuisances supplémentaires, ainsi qu'un bateau destiné à l'épuration d'eaux d'égout et permettant de mettre en pratique ledit procédé. Selon cette invention, on utilise un bateau servant à l'épuration d'eaux d'égout, sur lequel sont montés un dispositif à électrolyse de fluorure de calcium, une source de puissance à courant continu et un dispositif de déversement d'un coagulant. On fait fonctionner le dispositif à électrolyse et on déverse le coagulant dans un tuyau pourvu d'un ajutage diffuseur de coagulant. L'eau lacustre passant à travers des électrodes, est traitée à l'aide d'ions fluor et du coagulant, de sorte que les substances polluantes se coagulent et se transforment en flocons de grand diamètre. Ces flocons de grand diamètre sont ramenés dans le bateau par un dispositif de recouvrement ou amenés à couler au fond des lacs ou des marécages après avoir été réduits en volume au moyen d'une action hydrophobe sur les flocons, de sorte que l'eau des lacs et des marécages est ainsi épurée.

Title: Disclosed for purifying exhaust gases, in particular those from waste-incineration plants.
Inventor: RITTER JUERGEN
IPC: B01D53/64
Filed: 1991-04-13
Abstract: Disclosed is a process for the purification of exhaust gases (1) arising from waste-incineration plants, in particular incineration plants for household rubbish (2), in which dust is separated from the waste gases (1), and the gases conditioned and passed through an adsorber (6) filled with activated coke (7) to separate out the impurities. Unpurified waste gas (1) is then passed through the adsorber (6). The adsorption is controlled so that the gas (8) leaving the adsorber (6) is virtually SO2?-free. HCl and HF are extracted from the unpurified gas (8) leaving the adsorber (6) for the production of usable products, in particular hydrochloric acid and/or NaCl. By multiple adsorption (6, 14, 25, 36) and regeneration (20, 29), not only are the waste gases (1) purified but the impurities are isolated and further processed to give marketable products.

Abstract: L'invention se rapporte à un procédé servant à produire des gènes suppresseurs trans-dominants qui codent pour des sous-unités mutantes de deux catégories différentes de protéines oligomères. Dans l'une de ces catégories, la protéine est composée de sous-unités dont au moins une est initialement synthétisée et qui contiennent une substance peptidique étrangère. Cette substance peptidique étrangère est ensuite retirée pendant la transformation normale par clivage au niveau d'un site de clivage protéolytique, en vue de produire la forme mature de la sous-unité. Selon la présente invention, un ADN monocaténaire codant pour la forme initiale de la sous-unité indiquée est cloné et la séquence de base de l'ADN dans la région codant pour le site de clivage protéolytique est modifiée par mutagenèse orientée sur le site, de sorte que la transformation du produit de translation du gène en la forme mature de la sous-unité est empêchée. Dans l'autre catégorie, la protéine oligomère est une protéine dans laquelle les monomères sont liés ensemble par au moins deux liaisons disulfure, dont au moins une est essentielle pour l'activité catalytique de la protéine. Dans le procédé de cette invention, un ADN monocaténaire codant pour l'une des sous-unités est cloné et la séquence de base de l'ADN dans la région codant pour un résidu de cystéine essentiel pour l'activité catalytique est modifiée par mutagenèse orientée sur le site.

Abstract: There is provided a packet-rate control method for a packet network (1l - 1n, 2l - 2nl), in which a declaration of parameters indicating the rate of fixed-length packets is so made to a call control system (5) by a subscriber terminal device prior to communication as to be associated with a logical channel number (LC). The rate of packets inputted to the network is so measured (101) as to be associated with a logical channel number. While the degree of violation is low, packets transmitted in violation of user-declaring parameters are provided (103) with a violation mark and taken in the network. If the degree of violation is high, the packets transmitted in violation of user-declaring parameters are discarded (104, 107) on the input side of the network. When there appears a possibility of congestion in the network, the marked packets are discarded (113). As a result, it is possible to prevent violation packets and marked packets from affecting the quality of service using normal packets.

Abstract: The invention relates to a continuously variable V-belt transmission (1) with two V-belt pulleys (2, 3) which are coupled to one another in torque-transmitting fashion by a V-belt (4) and each of which has an axially fixed and an axially displaceable pulley half (5, 6; 7, 8). The axially displaceable pulley halves (6 and 8 respectively) of the two V-belt pulleys (2, 3) are each mounted in (to a limited extent) axially displaceable but rotationally fixed fashion on an axial sleeve extension (18 and 19 respectively) of the associated axially fixed pulley halves (5 and 7 respectively) which, for their part, are each connected in axially fixed but rotatable fashion to an input shaft (16) and an output shaft (17) respectively. Assigned to each of the two V-belt pulleys (2, 3) are pressure application devices (9) for the torque-dependent production of forces which press the respective pulley halves (5, 6; 7, 8) together axially, the said devices each comprising a radially aligned pin arrangement (11; 11', 11'') which is rotationally connected to the input shaft (16) or the output shaft (17) and, for its part, is in torque-transmitting line contact with an axially acting ramp arrangement (10) borne by the axially displaceable pulley half (6, 8), load-independent transmission by the V-belt transmission thereby being achieved. By means of a centrifugal device (12) acting on the input V-belt pulley (2) and intended for the purpose of producing axial expansion forces which force these pulley halves (5, 6) apart and by means of a pre-loaded spring device (15) interacting with the said centrifugal device and intended for the purpose of producing travel-dependent axial forces pressing these pulley halves (5, 6) together, it is ensured that the transmission ratio remains essentially independent of speed within a certain speed range. <IMAGE>
