Abstract: A pipe for the pneumatic transport of solid polymer particles has an internal diameter d and constrictions along its length, the distance between consecutive constrictions being between d and 10xd. The pipe can be used to transport polymer particles with the aid of a carrier gas at a gauge pressure of between 10 and 100 kPa, a temperature which is at least 5°C below the melting point of the polymer and a sufficient velocity to ensure turbulent flow of the mixture of carrier gas and the particles.

Abstract: La présente invention décrit un stéthoscope intelligent, qui sert à ausculter et à diagnostiquer automatiquement des anomalies sur la base des sons produits par le corps et dans lequel les sons produits par le corps sont captés, numérisés et stockés en mémoire. Les sons du corps sont enregistrés depuis plusieurs endroits situés sur le corps et tous les sons sont classés en catégories selon des caractéristiques spécifiques de façon à former une matrice d'informations. La matrice ainsi produite est ensuite comparée à plusieurs matrices stockées au moyen d'une technique similaire à la technique des analyses de signatures. Chacune des matrices stockées contient des informations indiquant des anomalies connues, telles que des murmures cardiaques spécifiques, des anomalies pulmonaires, etc. Lorsqu'une correspondance de matrices est trouvée, le diagnostic est affiché sur un écran de visualisation à cristaux liquides (102) formé dans le corps du stéthoscope. L'écran de visualisation à cristaux liquides (102) peut également afficher une représentation visuelle des sons du corps enregistrés. La présente invention peut s'appliquer à des sons cardiaques, à des sons pulmonaires et à d'autres bruits.

Abstract: An electrohydraulic system for bending tube stock (22) includes a bend head (12) having a mandrel (14) and an actuator (18) coupled to a bending die (16) for engaging the tube stock and bending the stock around the mandrel. A clamp (28) is coupled to a second actuator (32) for gripping the tube stock, and a third actuator mechanism in the form of a boost cylinder (40) is coupled to the clamp for urging the tube stock lengthwise into the bend head. An electrohydraulic valve (46) is responsive to an electronic valve control signal (U) for variably feeding hydraulic fluid to the boost cylinder, and velocity of slip at the clamp is determined. An input pressure command signal (PC) is compared with pressure at the boost cylinder to develop a pressure error signal. Slip velocity (V) is compared with a velocity limit command (Vl) to develop a velocity difference when slip velocity exceeds the velocity limit, and the pressure error signal (Ep) is modulated and employed as the valve command signal to maintain slip velocity at or below the level of the velocity limit command.

Abstract: A method for either block- or byte-erasing is described for an array of EEPROM cells, each having transistor channel regions with subchannels thereof respectively controlled by a floating gate conductor and a control gate. Erasing occurs through a Fowler-Nordheim tunnel window (34) between a source bit line (24) and a floating gate conductor (42) of a selected cell. For one or more selected cells, first and second erasing voltages are selected such that the selected source bit line (24) is more positive than the selected word line (48) by a voltage sufficient to cause excess electrons on the floating gate conductor (42) to be drawn through the tunnel window (34) to the source region (24). The nonselected word lines (48) have a nonerasing voltage impressed thereon that is sufficiently close to that of selected source regions that no erase disturb will occur in nonselected cells.

Abstract: The device serves to fix facade plates (P) with rear ventilation on a building (B). For this purpose, vertical rails (S) are fixed on the building (B), on which rails are fixed supporting brackets (1) fixed vertically adjustably at selectable distances. Each supporting bracket (1) has at least one, preferably two, upwardly directed supporting extensions (11) and a, preferably interposed, retaining spring (14) acting away from the building. Attached to the building-side rear (PR) of each facade plate (P) is a support (T). The support (T) is preferably T-shaped in cross-section, its downwardly projecting support web (2) engaging between the supporting extensions (11). The retaining spring (14) acts on the support (T), in this case preferably on the support web (T2), in such a way that the support flange (T1) is pressed by its two flange noses (T3, T4) in each case into one building-side horizontal retaining groove (12; 13) of each supporting extension (11). Each facade plate (P) is thereby individually mountable and demountable. Where a higher stability of the plate is desired, it can be provided below the said support (T) additionally with a further support (T) which cooperates with a bearing bracket (2). <IMAGE>
