摘要:
The invention relates to a coating installation for coating a metal strip (12) in a molten mass (14) of a non-magnetic metal, which is provided with a shaft (16) that rotates in the molten mass (14) and that guides the metal strip (12). Said shaft (16) is received by a bearing (261), said bearing (261) being a magnetic bearing whose stationary bearing part (281) is encapsulated, thereby providing a contactless bearing of the shaft in the molten bath. The inventive installation substantially reduces bearing wear and prolongs service life of the bearing.

A roll (20) for applying a sizing composition (L) to a fan (N) of one or more fibers (F), providing a shaft (22) having a curved central axis (CR) and a sleeve (24) covering at least a portion of the shaft, the sleeve being rotatable relative to the shaft. Each fiber of the fan of one or more fibers contacts the sleeve at an axial location of the sleeve such that each fiber of the fan of one or more fibers lies substantially in a plane perpendicular to the curved central axis of the shaft at the axial location.
摘要:
A method and system for registration of a sensing device for use with a computer system. The method includes providing a printed registration form including registration information and coded data thereon, the coded data including an indication of an identity of the form and at least one reference point on the form. The method also includes receiving in the computer system indicating data from a sensing device, the indicating data including information regarding an identity of the sensing device, the identity of the form and at least one action of the sensing device in relation to the form generated by the sensing device using at least some of the coded data. A correspondence is derived, from the indicating data, between a registered user of the computer system and the identity of the sensing device. Registration data associating an identity of the registered user with the identity of the sensing device is then stored in the computer system for later use.
摘要:
A roll apparatus for use within a bath of molten metal, such as a galvanizing bath, in which a moving metal strip is passed in two directions by passing around a roll, comprising: a first support arm and a second support arm, a strip-engaging roll having a length at least as great as the width of the moving metal strip, disposed between the lower portions of the support arms for rotation about said axis; a shaft telescopically received in the roll, and structure carried on at least one of said arms engaging the shaft such that the shaft is axially moveable, but non-rotatable with respect to the arms.

This invention provides a liquid metering and surface coating device which can satisfactorily perform the operation of applying a release liquid to at least the surface of toner image fixation rolls in plain paper copying, with exceptional accuracy, uniformity, and durability. The device comprises a porous support layer adhered to a metal shaft. The porous support layer is comprised of an open-celled thermosetting polymer foam internally reinforced to obtain the strenght, resilience, and heat resistance needed for high durability in use as part of a hot toner image fixation mechanism in a PPC machine. The porous support is comprised of materials having high compatibility with and wettability by the liquids to be distributed and having high liquid holding capacity so as to provide smooth continuous liquid delivery. Adhered to the porous support layer is a liquid permeation control layer which is comprised of porous polytetrafluroethylene film in which the pores contain a mixture of silicone oil and silicone rubber. Adhered to the outer surface of the liquid permeation control layer is a release layer which is comprised of a porous polytetrafluoroethylene film.
摘要:
The paint or decorating roller, which is intended to produce contrast effects with substantially unevenly-distributed impressions, such as those produced with pads, without showing an undesirable tendency to slip, is constituted by an array of flexible tuft-like decorating elements (2, 9, 19) which are fixed permanently or removably to the outer surface of the roller body (1, 15, 21) which is coupled for rotation on the straight front portion of a respective support arm (4, 17, 25), each tuft being formed by the pleating along at least two intersecting lines of an inner, central region of a flat piece of fabric, hide or other material having a regular or preferably even an indented outline; the roller is for use in the painting and decorating field in general.

Ein Klischee-Zylinder (1) zum Heißleim-Auftrag auf eine Papierbahn weist am Umfang in Rasterverteilung eine Vielzahl gesonderter, radial ausgerichteter und bis an seine Umfangsfläche (18) reichender, bis mindestens 300 °C temperaturfester Magnet-Einheiten (22) auf, die wie der im wesentlichen rohrförmige Werkzeug-Grundkörper (15) radial nach außen gerichtet beheizt werden und zur Halterung eines oder mehrerer gesonderter, biegeflexibler Hochdruck-Klischees dient.
摘要:
A liquid metering and coating device made of a liquid permeation control material (6, 16) including porous polytetrafluoroethylene, adhered to a porous support material (4, 14) of open-celled foam. The porous support (4, 14) and permeation control material (6, 16) contain mixtures of silicone oil and silicone rubber which bond to the porous support material (6, 16) and form an interconnected network of silicone rubber throughout the device. The device is suitable for use as a part of a toner fixation mechanism in a plain paper copying machine.
摘要:
Le dispositif d'encollage selon l'invention permet de garantir un encollage correct d'un ruban de papier (2), en contrôlant la qualité, respectivement la viscosité de la colle ainsi que la dimension du boudin (30) malaxé entre les deux rouleaux (10,12) dudit dispositif. Pour ceci, l'alimentation en colle du boudin se fait par des buses d'alimentation (34a,34b) projetant de fins jets de colle (35a,35b) de débit contrôlé. En cas d'augmentation de la viscosité mesurée ou d'arrêt du ruban de papier, un dispositif de pulvérisation d'eau (40) permet d'abaisser la valeur de la viscosité de la colle et d'éviter son desséchement. Une dimension dudit boudin est contrôlée et commande le réglage du débit des buses d'alimentation en colle.
