Patent EP-0637570-A1 (EP)
Inventor: AMER AMEZAGA SEBASTIAN
IPC: C02F1/72
Filed: 1994-02-11
Abstract: The present invention relates to the integral treatment of chromium containing wastes from tan-yards according to the diagram of figure (1). There is provided one or two solid (1) and/or liquid (2) effluents which contain chromium. The solid effluent is subjected to a treatment (4) with perborate (3) producing a chromium-free residue (5) which is treated by conventional methods (for example hydrolysis in order to produce gums or chelagen) and waters which contain the chromium present as Cr(VI). Said Cr(VI) is reduced to Cr(III) by redution in acid medium at (6). In a reactor (7) the solution containing Cr(III) is treated continuously with an alkaline solution (8), to give waters with less than 1 ppm of Cr(9) and a pulp (10) containing Cr(OH)₃.3H₂O from which is obtained, by acidification with sulphuric acid, a concentrated solution of chromium sulphate reusable in the same tan-yard. The present invention provides for the precipitation of Cr(III) contained in solutions, by using magnesium hydroxide (or mixture with NaOH); the chromium-containing solution is slowly and continuously added to another solution, maintained at a temperature between 60 and 63ºC, to which is also added the neutralizing agent. Thereby, the precipitate obtained has particular characteristics of solubility and settling which cannot be obtained in a precipitate produced with other neutralizers. In the solid wastes, the oxidation is performed by stirring these chopped wastes with an aqueous solution which contains a perborate in the proportion of at least 1.5 mol of BO₃ per at-g of Cr contained in the residues (for example 2.35 g of NaBO₃ per g of Cr), during a period of time longer than 10 minutes, the recommended amount of perborate to be used, if sodic salt is used, being from 3.3 to 3.7 g of NaBO₃ per g of Cr contained in the residue to be treated and the recommeded treatment time being 45 minutes. The perborate may be substituted by a mixture of oxygenated water, H₂O₂, and a borate (for example borax) in a solution whose pH must be comprised between 7.5 and 11.5, preferably between 8.5 and 9.5.

Title: Apparatus for agitating cigarette filters in a filter hopper
Inventor: LOWE BYRON L
IPC: A24C5/47
Filed: 1994-04-11
Abstract: An apparatus for agitating filters in a feed hopper (10) from which the filters (12) are fed pneumatically to a filter attaching machine. The hopper drive apparatus includes an independent drive and speed reducer (84) mechanism that continues to drive the filter agitators (64) when the filter attachment is running and when it stops, until the machine stops receiving filters. The agitation system (64) uses a stand alone independent drive system that uses a timing belt (80) to drive the agitators. This agitation system provides a means for operating with fragile, segmented charcoal filters in that the filters are permitted to move up and down more freely, than with conventional agitation devices, allowing more room for incoming filters from the receiver and reducing damage to the filters and jamming of the filters in the transfer system.

Date Dec. 8, 1994According to the invention, lead storage batteries are charged by intermittently switching on and off a battery-charging unit (1, 2, 3) which is connected to a battery. The on and off times are suitably about 1 second when charging a battery. In the case of a maintenance charge, it is suitable to charge the battery with pulses in the region of a mains voltage period, with pauses of about 10 seconds. The circuit is suitably broken by means of a switch (4, 5) on the primary side of the transformer (1, 2). The switch may have the form of a relay with associated time circuit (4), although it is preferred to use a triac.

Abstract: On décrit un mécanisme de régulation de flux destiné à un trafic à base de cellules dans un noeud ou une passerelle raccordés à une voie de transmission qui possède une vitesse rtot de transmission maximum ainsi qu'un temps D de transmission aller-retour, et qui dessert au moins une liaison, ce mécanisme de régulation de flux comprenant des moyens tampon destinés au stockage des cellules arrivantes ainsi que des moyens de réaction comportant des moyens générateurs de signaux afin d'envoyer des signaux de marche et d'arrêt (en direction des noeuds situés en amont); les moyens générateurs de signaux sont actionnés à un moment t qui est fonction du nombre V(t) de cellules supposées occuper les moyens tampon à un moment t+D. Par comparaison avec les mécanismes connus, les moyens de réaction comprennent un émulateur local destiné à enregistrer un moment disponible à l'intérieur d'une période t-D dans laquelle chacune des liaisons est susceptible de transmettre des cellules. En effet, le temps D de transmission aller-retour est remplacé par le temps disponible (plus court) aux fins d'une détermination ultérieure d'une limite supérieure du nombre de cellules arrivantes dans la période t, t+D. On décrit également un émulateur commun supplémentaire destiné à traiter le multiplexage ainsi que le trafic à vitesse régulée, et à évaluer une limite supérieure au nombre de cellules arrivantes, lesquelles doivent être stockées dans une portion partagée des moyens tampon. La dimension du tampon total est grandement réduite, notamment lors de l'utilisation d'une combinaison de tampon partagé et spécialisé.

Abstract: A floating gate is inserted into the gate stack of an EEPROM cell. For an N channel EEPROM device, the floating gate is composed of a material having a conduction band edge (or fermi energy in the case of a metal or composite that includes a metal) at least one and preferably several kT electron volts below the conduction band edge of the channel region. The floating gate material thus has a larger electron affinity than the material of the channel region. This allows the insulator separating the floating gate and the channel to be made suitable thin (less than10nm) to reduce the writing voltage and to increase the number of write cycles that can be done without failure, without having charge stored on the floating gate tunnel back out to the channel region during read operations. For a P channel EEPROM device, the floating gate is composed of a material having a valence band edge (or fermi energy in the case of a metal or a composite that includes a metal) at least one and preferably several kT (eV) above the valence band edge of the channel region.

Abstract: A magnet including spaced-apart first and second pole pieces with generally opposing first and second pole faces. The first pole face has an axis extending generally towards the second pole face and has a surface region which includes at least two frustoconical surfaces. The frustoconical surfaces are generally coaxially aligned about the axis, and radially-adjacent frustoconical surfaces abut each other. In a second embodiment, points on the surface region located an identical radial distance from the axis are also located a common axial distance along the axis, and a graph of axial distance along the axis versus radial distance from the axis for such points is a curve having a continuous slope with at least two sign reversals. Such contoured pole faces allow for a smoother magnetic field to better reduce axisymmetric magnetic field inhomogeneity.
