Abstract: For the desulphurisation of flue gases generated in a boiler by the additive process, ground limestone has, inter alia, hitherto been used. In sugar manufacture, a deliming sludge containing a calcium hydroxide, carbon dioxide and organic constituents is obtained. To utilise the deliming sludge as an additive, it is comminuted and dried in a continuous dryer with flue gas from the boiler. The dried deliming sludge is separated in a separator from the flue gas and conveyed by means of air to a plurality of blow-in points leading into the firing chamber of the boiler.

Abstract: Un dispositif détecteur de radiations (10), du type utilisé pour la détection de radiations infrarouges, se compose de deux récipients cylindriques en acier inoxydable (11, 19), l'un interne et l'autre externe, le récipient interne (19) étant suspendu à la paroi supérieure (13) du récipient externe (12) à l'aide d'un mince tube en acier inoxydable relativement long (24). Un organe de fixation (33) assurant un transfert thermique est fixé sur le fond du récipient interne (19) et s'étend vers l'extérieur et ensuite vers le haut entre les récipients, en s'en écartant, jusqu'à une ouverture en forme de fenêtre ménagée dans le récipient externe (11). Un capteur (36) est fixé de manière à assurer un bon contact thermique avec l'organe de fixation (33) au niveau de la fenêtre (17) et est maintenu essentiellement à la même température que la surface du fond du récipient interne. Les surfaces des récipients interne et externe peuvent être polies de manière à les rendre spéculaires, pour empêcher tout transfert thermique vers le récipient interne par rayonnement infrarouge. L'emploi de l'acier inoxydable pour le récipient externe permet également d'utiliser une structure de fenêtre (15) pour l'orifice de vide possédant un joint d'étanchéité métallique (47) réduisant au minimum l'infiltration potentielle de gaz.

Title: Chargeur de batterie non isole thermosensible
Inventor: WALTER RICHARD T
IPC: H02J7/10
Filed: 1987-09-01
Granted: 1994-06-01
Abstract: Un chargeur de batterie non isolé ayant un condensateur (C1) permettant un branchement direct sur une source C.A. (S), fournit à partir d'un pont à diodes (12) un courant C.C. redressé à la batterie (B) en cours de charge. Un thermostat (TS1'), en relation de thermoconduction avec la batterie (B), détecte la température de cette dernière et coupe le courant de charge lorsque la température de la batterie (B) s'élève après que cette dernière ait atteint la pleine charge. Dans un mode de réalisation de l'invention, il est prévu un trajet de charge de maintien menant à la batterie (B) pour maintenir son état de charge après qu'elle ait atteint la pleine charge. Ce trajet de charge de maintien est assuré par une impédance shuntant le thermostat (TS1') et fonctionne comme un trajet de courant lorsque ledit thermostat est à l'état ouvert. Le trajet de charge de maintien peut être une résistance (Rt) dans le cas où le thermostat (TS1') se trouve dans la partie C.C. du circuit de charge, ou bien un condensateur dans le cas où le thermostat se trouve dans la partie C.A. du circuit de charge. Une fonction de verrouillage peut être exécutée par une paire de thermostats (TS1', TS2) de sorte que le circuit de charge est ''verrouillé'' dans son état de fonctionnement en charge de maintien après avoir atteint le régime de pleine charge, ce qui empêche la fluctuation indésirable du courant de charge entre les régimes de pleine charge et de charge de maintien. Il peut être prévu un circuit de commutation permettant de fournir à une charge (M) le courant de charge et l'énergie emmagasinée dans la batterie (B), de sorte que le circuit du chargeur peut faire office d'alimentation supplémentaire ainsi que de chargeur de batterie.

A transport device connected to the residue sorting device transports the finer coarse components. A grinding apparatus has an inlet side connected to the transport device and a discharge side for feeding the finer coarse components to the combustion chamber after grinding. The combustion chamber maintains combustion gases produced from delivered combustible material for a sufficiently long time at a sufficient temperature level to produce molten slag. The combustion chamber has an outlet for removing the molten slag which is cooled into a glassified form downstream of the outlet of the combustion chamber. A flue gas line leads from the combustion chamber to a chimney.

Abstract: It has been proposed to employ a constant mesh gearbox of the kind having pairs of gears on parallel shafts (1, 2) in constant mesh with each other, together with a clutch, in an automatic vehicle transmission. A microprocessor controls actuators for the clutch and throttle and hydraulic actuators for moving the selector rod (3) of the gearbox, in order to give automatic operation of the gearbox. In accordance with the invention, a constant mesh gearbox of the kind referred to is provided with actuating means (6, 9) for moving the selector shaft (3) and, in at least one direction of travel of the selector rod (3), the actuating means acts via resilient means which is arranged to store the energy of the actuating means when the actuating means is operated but the selector rod is not free to move, the rod being moved by the energised resilient means when the selector rod becomes free. More rapid shifting, and when the gearbox forms part of an automatic transmission, a shorter period of interruption of power, is possible, and reversal of torque during a gearshift can also be avoided.

Granted: 1993-05-12
Abstract: A double drum batch washing machine comprises an inner cylinder, an outer cylinder, an inner helical transfer screw with the inner cylinder and an outer helical transfer screw within the space between the inner and outer cylinders. The inner helical transfer screw has a pitch in one direction and the outer helical transfer screw has a pitch in the other direction so that the compartments formed by the transfer screws within the inner cylinder and the space between the inner and outer cylinders define areas of overlap on the surface of the inner cylinder. The areas of overlap have holes formed therein so that fluid interchange is established between each outer compartment and only the corresponding overlapping inner compartment. Laundry is placed in the inner compartments and wash water is placed in the outer compartments such that it communicates with the inner compartments and the laundry contained therein. Laundry is washed by oscillating the washing machine through a predetermined angular arc. When the washing machine is rotated through a complete circle, laundry is transferred in one direction by the inner helical transfer screw and wash water is transferred in the opposite direction by the outer transfer screw.

Abstract: Nouvelle structure d'électrode du type entourant la totalité de la périphérie, servant à alimenter une tête d'impression thermique. Cette configuration fait correspondre une électrode discrète à une partie thermogène sans séparer une résistance thermogène de manière à la rendre indépendante. La présente invention permet ainsi d'améliorer le rendement thermique à l'impression, d'accroître la réaction thermique et de réduire la consommation énergétique. En outre, étant donné que l'invention utilise une structure dans laquelle la résistance thermogène recouvre entièrement la partie d'électrode du type entourant la totalité de la périphérie, on élimine toute non-uniformité de la valeur de résistance de chaque point résultant de la non-uniformité de la largeur d'impression de la résistance, tandis que les valeurs de la résistance sont rendues entièrement uniformes par un système de régulation de surcharge de l'alimentation, et le rendement thermique et la réaction thermique sont améliorés. On réalise ainsi une tête d'impression de grande qualité, tout en rendant uniforme la densité d'impression de chaque point et en améliorant la reproduction des dégradés.
