IPC: H02K17/08
Filed: 1992-10-28
Abstract: An autotransformer is used to replace the start capacitor in a split phase induction motor. The autotransformer windings are protected by a PTC resistor which also serves to effectively de-energize the auxiliary winding. In a preferred embodiment, efficiency of the motor in the run mode is enhanced by shunting the secondary of the autotransformer with an NTC element. In alternative embodiments a relay coil is placed in series with the auxiliary winding circuit to remove the PTC and the primary of the autotransformer from the circuit when the motor is in the run mode.

Abstract: Mémoire RAM dynamique (DRAM) assurant un rafraîchissement synchrone de ses cellules de mémoire. Le rafraîchissement s'effectue pendant un segment de rafraîchissement du cycle d'horloge. Selon un mode préféré de réalisation, la DRAM sélectionne, immédiatement avant le début de chaque cycle d'horloge, une ligne de mots pour une ligne de cellules de mémoire pour lesquelles un accès à l'information doit se produire. La DRAM sélectionne également au moins une ligne de mots pour au moins une ligne de cellules de mémoire pour lesquelles un rafraîchissement doit se produire. Au cours du cycle de rafraîchissement, chaque ligne de cellules de mémoire sélectionnée pour l'accès à l'information ou pour le rafraîchissement subit un rafraîchissement. Après ledit cycle de rafraîchissement, et pendant un segment d'accès à l'information dudit cycle d'horloge, la DRAM continue à sélectionner la ligne de mots pour la ligne de cellules de mémoire pour lesquelles l'accès à l'information doit se produire. Cependant, la DRAM ne sélectionne plus ladite ligne de mots pour ladite ligne de cellules de mémoire sélectionnée pour le rafraîchissement. Pendant le segment d'accès à l'information du cycle d'horloge, ledit accès à l'information s'effectue sur la ligne de cellules de mémoire qui demeure sélectionnée.

Abstract: Procédé de signalisation/de communication mis en oeuvre dans un système téléphonique d'entrée d'habitation ou analogue, et système utilisant ce procédé. Le procédé rend plus aisée la communication sélective entre un poste central d'entrée ou une unité centrale (1) et une sous-station voulue (5, 5', 5'') adressée, par l'intermédiaire d'une boucle comprenant au moins deux conducteurs, tout en rendant aussi plus aisée l'ouverture d'un verrou de porte d'entrée ou une fonction similaire à partir d'une telle sous-station (5, 5', 5''). Après qu'un visiteur ait effectué une opération d'adressage approuvée à l'intention de l'unité centrale (1), celle-ci alimente la boucle (2, 2') reliant l'unité centrale (1) et des sous-stations connectées (5, 5', 5'') en un courant de travail, et transmet un code d'adresse unique spécifique à la sous-station adressée (5, 5', 5''). Grâce à un dispositif de détection (6, 6', 6'') de signal, seule la sous-station adressée établit une connexion galvanique avec la boucle (2, 2') et l'unité centrale (1). Celle-ci produit ensuite un signal sous forme de sonnerie, détecte un état de "décrochage" ou d'autres changements d'état ou de signalisation, et, lorsqu'elle détecte une réponse non achevée ou la fin du processus de communication/fonction du téléphone d'entrée d'habitation, elle interrompt l'alimentation de la boucle en courant de travail. L'information relative à l'adressage provenant de l'unité centrale (1), est de préférence transférée à l'aide d'un type de signal différent de celui au moyen duquel les sous-stations (5, 5', 5'') connectées à la boucle (2, 2') peuvent influencer l'unité centrale (1) au cours d'une connexion établie pour déclencher l'ouverture de la porte d'entrée ou effectuer toute autre fonction.

Abstract: The invention relates to additives for conditioning and preliminary dewatering and for downstream solidification of sewage sludges and organic sludges, which exhibit the following features:   (I) they contain at least two components, of which at least one component is selected from the group A which comprises:     (A) fine lime (CaO) and   hydrated lime (Ca(OH)2), and one further or two further components selected from the group B, which comprises:     (B) clays and   kieselguhr;   (II) the weight fractions of the components A and B in the total mass of A and B, the sum of which is always 100% by mass, are as follows:     total mass fraction A: 50 to 98% by mass,   total mass fraction B: 2 to 50% by mass     The invention further relates to processes for the preparation and the use of these additives for the production of sludges suitable for landfilling. These additives, in the sludge solidification, in comparison with conventional additives, lead to significantly higher, adjustable firmnesses of the solidified products, which at the same time have lower extractability and thus give a low leaching water load in landfills. The conditioning according to the invention leads to higher dry matter contents of the pre-dewatered products.

Abstract: Silicide targets for sputtering which have an area ratio of silicon phases that appear on the sputter surface of no more than 23%, and a density of at least 99%, with a deformed layer partly removed from the surface to attain a surface roughness of from more than 0.05 µm to 1 µm, preferably with the number of coarse silicon phases at least 10 µm in diameter that appear on the sputter surface being at most 10/mm². The reduction of early-stage particle generation, in turn, reduces secondary particle generation, thus realizing the reduction of particle generation at both early stage and stabilized stage. A Si powder having a maximum particle diameter of no more than 20 µm is mixed with a metal powder having a maximum particle diameter of no more than 60 µm, in a rather Si-lower mixing ratio. A silicide powder is synthesized from the mixture and hot pressed, the sintered compact being machined and surface treated for the removal of the deformed layer. The burden of the deformed layer-removal step on the process is light.

Abstract: Reciprocating engines which feature conversion units are each formed of an expansion cylinder (4), a compression cylinder (2) and a passageway (6) connecting the two. Pistons (3,1) in the cylinders (4,3) are preferably connected via a four-bar or other linkage (12,13,14) to the crank or other rotatable means (11) so that the compression piston (1) remains at substantially its top-most position for a substantial portion of the stroke of the expansion piston (3), and vice versa. Communication between the cylinders (4,2) via the passageway (6) may thus be continuously open with no substantial pressure drop between cylinders. Fuel may be injected into the air or other gas moving between cylinders (4,2) giving an internal combustion engine, or the gas may be heated by external means. Devices according to this concept limit peak pressure and temperatures, resulting in the formation of fewer nitrous oxides. The expansion displacement volume may be larger than the compression displacement volume, and the strokes of the compression and expansion pistons (1,3) may differ, in order to provide fuller expansion of the combustion gases and increase efficiency.

Abstract: A flame detection apparatus and method includes a camera, preferably operating in the near I.R. which produces a succession of images of a space to be monitored. The image intensity of each pixel in each image is converted to a binary value by comparing it with the average intensity value for that image. For each pixel in an image the average intensity value for all of the images is calculated. The binary intensity value of each pixel in an image is then compared with the binary intensity value of the corresponding pixels in all the other images to produce a crossing frequency value dependent on the number of times those binary values change state. The average intensity values and the crossing frequency values are then processed for each pixel according to a predetermined relationship to produce a constant. If the values of this constant for a cluster of adjacent pixels are found to be the same or nearly so, this is considered to indicate a flame. The crossing frequency values may be processed to eliminate those values lying outside a frequency range corresponding to flames so as to eliminate the corresponding pixels from the final assessment step.

Abstract: To remove pollutants from the fumes produced in a boiler (1), the fumes, which are diverted off from a section of a chimney (13), are passed from the bottom upwards through a heat exchanger (3), in its entirety, to recover the latent heat of the water in the fumes. At the head of the exchanger (31) water is sprayed, which is drawn from a reserve capacity (50), and to which a soda solution (52) has been added to neutralise the sulphur oxides and part of the CO2. An effluent consisting of sprayed water laden with sulphite, sulphate and carbonates, condensates, and of the soot knocked down is collected in the tank (33) at the bottom of the exchanger (3). The effluent is taken from the bottom tank (33) and, after addition of a dose of flocculant (45) is conveyed to a separator (4) where the sludge settles at the bottom (41), while the clear effluent returns to the reserve capacity (50). An overflow (55) removes the excess effluent from the condensates. <IMAGE>
