Abstract: The distributor, associated with a cigarette machine, makes it possible not only to carry out its usual functions of conveying, metering out and forming an intermediate stock of tobacco, but also to separate out the leaf veins and foreign objects from the main stream of tobacco. This operation is performed without damaging the strands of tobacco. To achieve this, the distributor (1) comprises a flotation chamber (14) into which a strong draught of air is blown (14a) and which is separated into two parts by a deflector (14b). In this way, the main stream of tobacco (23) floats to the top of the chamber, whereas the veins and foreign bodies (22) escape under gravity and drop to the bottom of the chamber (14c). The adjustable position of the deflector inside the chamber makes it possible to create high-pressure and low-pressure areas, so that strands of tobacco entrained with the waste can be recovered. <IMAGE>

Abstract: To facilitate and speed up the laying of false floors having floor slabs (6) resting on regularly arranged supports (5), an auxiliary plane is levelled at a distance above the bare floor (1) in each case above an array (3) of grid points (2). A device (10) having a frame (11) and extension arms (12) is used to define the auxiliary plane and detachably hold and introduce a plurality of supports (5) simultaneously. The supports are then adjusted in height and fixed on the grid points (2) in accordance with the respective distance between auxiliary plane and (uneven) bare floor (1). After removing the device (10) and thereby freeing the supports, the slabs (6) are then laid on the accurately positioned head parts of the supports. 
<??>Various alternative embodiments of the method, the device (10) and also particularly suitable prefabricated supports (5) are described. In the case of the latter, head part and foot part are guided loosely with respect to one another and are displaceable in the direction of the support axis without mutual rotation. After the height adjustment, the relative position of the parts is fixed by means of locking means.

Abstract: Des matériaux optiques sensibles tels que des capteurs (18) ou l'oeil humain sont protégés de manière passive (10) contre la surexposition à la lumière de haute intensité (20) dans le domaine de la visibilté en utilisant un composé en grappe organométallique à solution à absorption saturable inverse (14) ayant un noyau d'au moins deux atomes à métal de transition et à liaison multiple, choisis à partir du groupe 8, 6b ou 7b de la table périodique. Les atomes-noyaux sont liés au moyen de ligands qui permettent la formation d'un complexe. Un composé en grappe organométallique préféré est le tétramère de fer carbonyle cyclopentadiényle. A mesure que l'intensité de la lumière incidente augmente, l'intensité de la lumière transmise augmente aussi jusqu'au niveau de saturation, mais au-dessus du niveau de saturation, l'intensité de la lumière transmise demeure pratiquement constante même lorsque la lumière incidente augmente.

Abstract: Carte combinée possédant un élément masque frontal (1) et un élément dorsal (2) fixés l'un à l'autre et renfermant entre eux au moins deux éléments coulissants (5, 6) disposés pour glisser l'un à côté de l'autre. Dans le sens de son glissement, chaque élément présente une série de caractères imprimés et l'un quelconque de ces caractères peut devenir visible lorsque l'on fait glisser l'élément derrière une fenêtre (9) ménagée dans ledit élément masque frontal ou dans ledit élément dorsal. L'élément frontal possède une fenêtre arrière (9) rendant visible une partie de la surface inscriptible desdits éléments coulissants. Un positionnement univalent prédéterminé des éléments l'un par rapport à l'autre correspond à un code d'accès auto-attribué constitué des caractères visibles à travers lesdites fenêtres. Lorsque les éléments coulissants sont ainsi positionnés, on peut inscrire des codes personnels et des données dans des cases qui recouvrent la partie visible de la surface desdits éléments. On peut inscrire dans les cases laissées vides des caractères semblables à ceux utilisés pour enregistrer les codes personnels, de sorte qu'un décodage soit quasi impossible si l'on ne connaît pas le code d'accès composé par un positionnement approprié desdits éléments coulissants.

In this arrangement, each guide element (15) has a guide section (19) which adjoins a fastening section (17) for connecting to the supporting device (3), extends at a predeterminable angle (a) obliquely from the supporting device (3) and engages in a through-opening during holding of the object (1), so that the object (1) is guided over the guide sections (19) for holding. Each guide section (19) is arranged and/or designed in such a way that, after pushing onto the guide elements (15), the object (1) can be swivelled in the direction of the supporting device (3). <IMAGE>

Abstract: A coded card key (14) is insertable through a slot (15) to bring into alignment coded magnetic areas on the card with magnetic pins (28) of the lock to unlock a core (24) relative to a locking plate (21) and enable the core (24) to be driven downwardly by the card engaging its lower flange (26) and to actuate an apparatus, typically a door-lock. 
     The core (24) has a cam having a first cam part (54) which is engageable by the card (14) and a second cam part (55) which abuts a limit spring (56) when the core (24) has reached the unlock position, whereby the core (24) keeps the unlock position as long as the card (14) engages the cam part (54). Withdrawal of the card (14) by the user allows return movement of core (24). 
     The user can release the card for actuating e.g. a door-knob, instead of having to hold the card down in the lock while rotating the door-knob.

Abstract: A container has on a neck portion thereof an external thread for a screw cap and, above the thread a sloping plane in the form of a spiral running around the outside of the container neck over an angle of 360 degrees. A head piece fitted into the container neck has a cylindrical part which bears on the inner side of the container neck and is held firmly on the container neck by a groove-bead connection formed on the outside of the cylindrical and on the inner side of the container neck. A cylindrical part of larger diameter, connected in one piece with the cylindrical part of the head piece, encloses the container neck on the outer side thereof and has on the inner side a sloping plane in the form of a peripheral spiral. The spiral surfaces lie on one another like the flanks of a thread. When the head piece is turned, therefore, the groove-bead connection is released by a wedge effect. The head piece can be removed for reuse of the container by being refilled. The head piece has a cup-shaped part which is connected in one piece at the center with the cylindrical parts and in which there are formed slit nozzles for the medium to be discharged.
