Abstract: A reaction tray specially suited for membrane hybridizations is disclosed. A tray 102 manufac­tured of firm but inexpensive material has a flat bottom. A firm but flexible overlay 106 is placed atop a membrane to evenly distribute a freely diffusing reactant, hinder evaporation, and avoid contamination. A lid 104 is friction fit onto the tray 102. The tray assembly 102/104/106 is floated on a water bath for the duration of the hybridiza­tion reaction. Manual handling of dangerous reactants and the delicate membrane is minimized. Low manufacturing costs allow the tray assembly to be disposable after a single use.

Abstract: A mandrel which can be supplied with pressurised fluid is proposed for the widening of portions of a tube in order simultaneously to fix a plurality of external construction elements, such as cams, bearings or gears, with a cylindrical basic body and seal elements and distance sleeves slipped onto the latter alternately, it being possible to separate those portions of the tube which are to be widened from those portions of the tube which remain undeformed by means of the seal elements. According to the invention, the mandrel is distinguished by the fact that a device for bringing the distance sleeves closer together axially, simultaneously compressing and radially expanding the seal elements to press them against the inside of the tube, and means for limiting the axial displacement path of at least some of the distance sleeves relative to the basic body of the mandrel are provided. The mandrel thus produced makes possible simultaneous, positionally accurate widening of individual portions of the tube in exact association with construction elements slipped on, and, while being of simple structural design, makes possible better sealing than known mandrels for widening several portions while providing good stability under load of the seals and easy introduction of the mandrel into the tube. <IMAGE>

Abstract: A sheet feeding apparatus in a printer is provided with: feeding rollers (112,126) for holding and feeding a sheet of paper therebetween; and an operation lever for changing the contact pressure of the feeding rollers (112) by attaching or detaching the feeding roller to or from the opposite feeding roller (114) depending on a type of sheet, e.g., a continuous form transferred by pin tractors or a manually inserted cut sheet. The operation lever also connects or disconnects a clutch mechanism provided between a drive motor (121) and the pin tractors (148) simultaneously with the attaching/detaching operation for the feeding rollers. A single operation of the operation lever can achieve a precise transfer of a selected type of sheet while suspending another type of sheet in the printer. The sheet feeding apparatus is also provided with a transmission mechanism (132,138) for transmitting a torque between the platen (107) and the feeding rollers by a friction driving force. The transmission mechanism prevents the inertia force of the platen from rotating the feeding rollers uselessly.

Abstract: This invention relates to a method of hot rolling a high-silicon steel plate. According to the present invention, leader strips, each of which consists of a metallic material having superior cold and hot processability, are joined to both end portions of a high-silicon steel plate, and the other end portions of the leader strips are fixed to tension reels, the high-silicon steel plate being then subjected to hot rolling. The preheating of the rolling rolls can be done by passing preheated leader strips through the rolls. In order to carry out a reverse rolling operation, the two tension reels are set in the heat retaining furnaces, and the heat of the steel plate is retained between reverse rolling passes so as to set at least one leader strip to a length larger than the distance between the tension reels, whereby the temperature drop can be compensated for along the whole length of the steel plate.

Dans une seconde variante visant à brosser les surfaces larges de lame dans le voisinage de son bord, une brosse à disque est montée sur un chariot pourvu d'un moteur destiné à imprimer un mouvement rotatif à la brosse. Là encore, le chariot peut glisser transversalement par rapport à la lame. Un dispositif pousse le chariot vers l'intérieur en direction de la lame de manière que la brosse soit constamment en contact avec une partie uniforme de la largeur de la lame, près du bord de celle-ci. Un deuxième dispositif est prévu pour maintenir une pression constante de la brosse contre la lame.

Abstract: According to the invention, an installation for electrostatic powder-coating (1) is indicated, which has a cubicle (2) in which the objects to be coated (3) are coated during the electrostatic powder-coating. The filter device (11) for powder recovery from the powder/air mixture in the cubicle (2) here comprises an air box (12), in which a vacuum prevails, and one or more revolving endless filter belts (13), the filter device extending wholly or partially beyond the wall surfaces of the cubicle (2). In this filter device, the powder is continuously and steadily filtered out of the powder/air mixture and then transported by means of the filter belt (13) to one or more powder-collecting tank(s) (19). By means of an electrostatic blow-off device (17), the powder which has remained adhering to the outer section of the filter belt (13) is blown into the powder-collecting tank (19), the powder first passing through a screen device (20). The filter device (11) can be subdivided into a plurality of filter part units which are associated, for example, with the side wall surfaces, the bottom surface and/or the cover surface and/or the rear wall. The blow-off device (17) is located in a vacuum-free zone. An embodiment of such an installation is also described, in which the cubicle walls are formed directly by the filter device and the installation has a frame-like base structure, on which the filter device and/or the filter part units are then mounted for displacement and uncoupling for the purpose of fine cleaning or for a rapid colour change in the case of contrasting colours. <IMAGE>
