Abstract: Bouteilles en plastique (10) avec une poignee attachable (12) pour lever, transporter et verser. La poignee (12) possede une forme generale en L. Une branche (26) de la poignee coopere avec le goulot (14) de la bouteille (10) et est fixee a celui-ci et l'autre branche (28) coopere avec la paroi laterale de la bouteille. Lorsque la poignee (12) est attachee, la branche (26) est horizontale et peut etre fixee par pression ou autrement sur le col (14) de la bouteille (10) et l'autre branche (28) est generalement verticale et peut s'engager avec la paroi laterale de la bouteille (10) ou s'attacher a cette paroi laterale par interverrouillage, soudage, liaison, adhesion, bandage ou autre moyen De meme, lorsque la poignee (12) est attachee, elle est placee sensiblement dans la largeur de la bouteille (10). Lors de la formation de la bouteille (10) et de la poignee (12) de la presente invention, des moyens peuvent etre prevus pour l'alignement correct de la poignee (12) et de la bouteille (10) pour faciliter la cooperation et la fixation entre les deux. Dans un mode preferentiel de realisation, la presente invention permet d'obtenir une grande bouteille pressurisee orientee biaxialement (10) avec une poignee attachable de levage, de transport et de versement sans nuire a la forme et aux proprietes desirees de la bouteille (10).

Abstract: A fluid flow diverter includes a housing (52) and a rotatable sleeve (57) mounted for rotation on an axle (62) and spaced inwardly from the housing walls (53, 54, 55). The sleeve and housing include ports (69, 70, 73, 74, 77-80) which are selectively positioned in registered or unregistered relationship, depending upon which of two operative positions the sleeve assumes. The sleeve forms a single internal chamber (57a) through which fluid always flows in the same direction in both operative positions of the sleeve. The space between the sleeve and housing also forms a single chamber (61) through which fluid always flows in the same direction in both operative positions of the sleeve. The unidirectional fluid flow through the sleeve itself is opposite to the unidirectional fluid flow through the external chamber between the housing and sleeve. The supporting connection between the cylindrical sleeve and housing walls occurs adjacent the registered sleeve and housing ports by means of mating peripheral supporting surfaces (85-88, 89-91). In either position of the sleeve, the unused or unregistered sleeve ports face the interior wall of the housing with their supporting surfaces spaced therefrom. A filler member (92, 93, 94) is mounted to the housing interior wall adjacent the position of each unregistered sleeve supporting surface.

Abstract: 1. Pressure-limiting valve with electrical adjustment of the response setting, and with the following features : a) in the valve housing (3), the pressure which is to be limited (system pressure) is led to an outlet opening (12) which, at pressures below the response setting, b) is closed by a valve element (14) which c) is forced onto the outlet opening (12) by the force of a valve spring (15), the outlet opening (12) serving as a valve seat and the valve spring (15) d) being supported against a spring seat (16) which can be adjusted continuously, e) the position of this spring seat (16) being determinable by means of a displacement transducer (20) which emits an electrical displacement signal (U actual ) representative of the seat position ; f) a comparator (25) compares the electrical displacement signal (U actual ) with a selectable, set-point value (U set ) and emits a corrective signal (U correct ) which, g) after amplification, influences the position of the spring seat (16) in the sense of a closed control loop ; characterized by the following measures : h) an electrically controllable valve arrangement (27), to which the system pressure is supplied, serves to amplify the corrective signal, converting it to a hydraulic force for the purpose of adjusting the spring seat (16) ; i) the outlet opening (12) is located within a stepped piston (7), the hydraulic pressure to be monitored being directed onto the smaller piston surface (7b), while the larger piston surface (7a) contains the outlet opening (12) and, outside this opening (12), is at a low pressure, as is also the difference-surface (7c) ; j) as the pressure rises, the stepped piston (7) can be slidably displaced, towards a stop (13).

Abstract: Bei einem kraftbetätigten Spannfutter (1') für Drehmaschinen, dessen Backen (4') mittels Keilstangen (7') antreibbar sind, ist den diese aufnehmenden Taschen (6') eine Freisparung (63) zugeordnet und die Keilstangen (7') sind jeweils mit einem in diese ragenden Fliehgewicht (61) versehen. Außerdem weist der Futterkörper (2') bzw. die Keilstangen (7') Kipplager (62) auf, an denen die Keilstangen (7') abgestützt und mittels denen die bei Rotation des Futterkörpers (2') auftretende Zentrifugalkraft eines Fliehgewichtes in eine auf die zugeordnete Keilstange (7') im Bereich der Zahnleisten (8') radial nach innen gerichtete Kraft umlenkbar ist. Durch diese Ausgestaltung wird die bei Rotation des Spannfutters (1') von den Backen (4') hervorgerufene Zentrifugalkraft selbsttätig ausgeglichen, ohne daß dabei das auf die Keilstangen (7') einwirkende Verstellglied (11') entlastet und ohne daß somit eine Erhöhung der statischen Spannkraft nach einem Bearbeitungsvorgang eintritt. Die von den Fliehgewichten (61) hervorgerufenen Zentrifugalkräfte werden vielmehr auf den mit den Zahnleisten (8') versehenen Teil der Keilstange (7') übertragen.

Abstract: A simple and inexpensive apparatus for treating a floppy disk (22) with conditioning fluid in order to clean, lubricate and destaticize the floppy disk is described. The apparatus (20) comprises a means for grasping the floppy disk about its center and rotating it, fluid absorbing pads (56) which are moveable into and out of contact with the magnetic surfaces of the floppy disk (22) through the read/write opening (28) in the floppy disk envelope (24) by mechanical means and a means for dispensing fluid to the pads. In one preferred embodiment, the mechanical rotation of a lever (108) causes the floppy disk (22) to be grasped and released through the cooperation of an axial cam (54) and a pin (50) riding on the cam. Rotation of the lever (108) also moves the pads (56) into and out of contact with the floppy disk (22). In a second preferred embodiment, a timer provided with a gear wheel controls an axial cam for grasping and releasing the floppy disk and a radial cam which moves the pads (56) into and out of contact with the floppy disk (22).

Abstract: A panel (10) adapted for securement to a mudguard, wing or wheel arch of a motor vehicle comprises a plurality, e.g. three, superimposed inhibiting mesh layers (11, 12, 13) separated from one another by spacers, e.g. spacer mesh layers (14, 15, 16, 17), having larger interstices than said inhibiting layers. The panel (10), when attached adjacent each wheel of a vehicle, provides a reticulate matrix which tends to prevent water thrown up by the vehicle's wheels from rebounding back onto said wheels, thereby reducing the overall amount of spray produced and improving the driver's visibility. There is a gutter (24).

Des images latentes magnetiques sont creees sur le support (13) par l'intermediaire d'une tete d'enregistrement a multi-elements qui inverse localement la magnetisation en unites d'elements d'image disposes selectivement en matrices. Le sens de magnetisation associe a chaque element d'image est, dans tous les cas, le meme.

Abstract: The method works by marking the flaw-related stray fluxes by means of dry magnetic powder, a yoke magnetisation with a magnetic field extending transversely to the longitudinal direction of the rod and parallel to the workpiece surface and close to the surface inside the workpiece being used in contrast to the conventional saturation magnetisation with its contacting problems. The markings can also be transferred in the correct position or shape to an imaging medium, particularly by means of photo-electric scanning and data storage of the flaw signals. After the imaging, the marking agent can be removed, which makes it possible to use marking agents free of binding agents or fixing agents. Depending on the flaw imaging, a controlled secondary marking of the flaws can then be carried out without removing the first flaw marking and possibly also a selective fixing with corresponding saving in fixing agent. The device comprises a magnetisation yoke arrangement (J, MP) with alternating flux exciter device and a device for repeating the operation, comprising a rotating device for covering various circumferential areas of the workpiece. Instead, a sequential arrangement of a plurality of treatment stations (I, II) with marking and detection devices rotated with respect to one another can be considered. <IMAGE>
