Abstract: In an electrographic printing apparatus, a dielectric belt cleaning system includes counter-rotating pairs (34, 36-38, 40) of adjoining cylinders mounted to a housing (24) (24). A vacuum source (67) forces the dielectric belt (10) in free span against the surfaces of the cylinders which are each covered by a brush (54) including a directional raised nap. Residual toner (88) on the belt is dislodged and drawn through a low pressure zone between each pair of cylinders leading to a filtered discharge outlet. The brushes (54) are cleaned by their interengagement along adjacent cylinder surfaces where the cylinder brushes (54) mesh and also between each cylinder brush (54) and a rake (74) therefor fixed to the housing (24).

Abstract: Dispositif de retenue d'une clavette comportant un ensemble de pièces pour maintenir sur leur fixation les pointes à travailler la terre. Il est extrêmement important, du point de vue opérationnel comme du point de vue économique, de bien maintenir sur leur fixation les pointes à travailler la terre au moyen de leurs clavettes de retenue pendant toute la durée du travail. En effet, quand ces pointes sont perdues, il faut les remplacer ou les réparer, ce qui non seulement fait perdre du temps mais se répercute sur la production. S'il faut, certes, bien maintenir ces pointes en place, celles-ci doivent cependant pouvoir être rapidement enlevées en vue de leur remplacement. Les pièces de retenue (44) de la clavette (17) viennent s'insérer dans un évidement (28) situé entre un bec (16) de la pièce de fixation (12) et une paroi latérale (36) de la pointe (14) et comportent une rondelle (46) glissée sur la clavette (17) et une bague de retenue élastique (68, 78), d'une épaisseur radiale prédéterminée, s'engageant dans une rainure (21) disposée sur la clavette (17) ainsi que dans une rainure de la rondelle (46) pour provoquer un verrouillage. L'une des rainures (21, 50) de la clavette (17) et de la rondelle ont une profondeur égale ou supérieure à l'épaisseur radiale prédéterminée de la bague de retenue (68, 78) et l'autre rainure (21, 50) a une profondeur suffisante pour empêcher que la bague (68, 78) fasse saillie hors de la rainure (21, 50) et que la largeur de la section transversale de la bague (68, 78), exposée au cisaillement, soit maximale. Pour enlever la clavette (18), on doit cisailler la bague (68, 78) on casser la rondelle (46).

Abstract: A surface-segregatable, melt-extrudable thermoplastic composition suitable for processing by melt extrusion to form a fiber or film having a differential, increasing concentration of an additive from the center of the fiber or film to the surface thereof, which differential, increasing concentration imparts to the surface of the fiber or film at least one desired characteristic which otherwise would not be present, which composition includes at least one thermoplastic polymer and at least one defined additive. During formation of the fiber or film, the additive rapidly segregates in a controllable manner toward the newly-formed surface of the fiber or film, thereby resulting in a controllable differential concentration of the polymeric material, which concentration increases with increasing distance from the center of the fiber or film to its surface. The thermoplastic composition is useful in the preparation of fibers or films which have at least one surface characteristic which is different from that of the polymer component of the thermoplastic composition. Methods for preparing the fibers or films and for stabilizing the thermoplastic compositions under certain conditions also are disclosed. The thermoplastic composition is particularly useful in the formation of nonwoven webs which are used in the construction of such disposable absorbent products as diapers, feminine care products, incontinence products, and the like. <IMAGE>

Abstract: The invention relates to a tap device to dispense fluid fuels, having at least two delivery nozzles (3) which are supplied with fuel, in each case via their own measuring device (6), from a common pump (9) having a downstream gas separator (11). The pump (9) is driven by an electric motor (10) which is switched on when a delivery nozzle (3) is removed from its mounting (7). Fuel is conveyed via a bypass line (15) in a closed circuit until the delivery nozzle (3) is opened. To reduce to a minimum the formation of gas bubbles owing to the fuel conveyed via the bypass line (15) in the closed circuit and consequently the elimination of additives which improve the fuel quality, the delivery rate of the pump (9) is regulated by a regulator (21 and 22) either as a function of the measurement result of a flow meter (20) built into the bypass line (15) or controlled as a function of the number of delivery nozzles (3) removed from their mounting, in accordance with their proportion of the total delivery quantity. <IMAGE>

Abstract: The present invention relates to branching directional couplers with a voltage and a current transformer and an internal terminating resistance, in which the junction of the secondary windings of the two transformers forms the branch and the internal terminating resistance is inserted between the secondary winding of the voltage transformer and earth. To achieve branch attenuations of >/= 16 dB in such a branching directional coupler, with little circuit complexity over a wide band up to 1.75 GHz with little transmission loss, a high degree of decoupling and good matching of all connections, an ohmic resistance connected in parallel with the secondary winding of the current transformer and connected to the latter with low inductance is provided which, together with the transformation ratios of the two transformers, is selected in such a manner that the nominal values for the branch attenuation and impedance are obtained as accurately as possible at the branch connection. By inserting a further ohmic resistance between the junction of the secondary windings of the two transformers and the branch connection, a further degree of freedom has been advantageously achieved for the choice of resistances and transformation ratios. <IMAGE>
