Methods and apparatus for applying adhesives in patterns to an advancing substrate

Methods and apparatuses herein may provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to an advancing substrate. The fluid application apparatus may include a slot die applicator and a substrate carrier. The substrate carrier may include one or more pattern elements and may be adapted to advance the substrate past the slot die applicator as the slot die applicator discharges adhesive onto the substrate. In operation, the substrate is disposed on the substrate carrier; the substrate carrier advances the substrate past the slot opening of the slot die applicator. In turn, the substrate is intermittently compressed between the slot die applicator and the pattern surface of the pattern element. As the substrate is intermittently compressed, adhesive discharged from the slot die applicator is applied onto the substrate in an area having a shape substantially the same as a shape defined by the pattern surface.

Process of controlled shuffling of chromosone fragments for plant breeding

Disclosed is a method of constructing a wild-species genomic library of chromosome fragments incorporated in a crop-species genome. First, a number of transformants for donor and recipient plant species is produced, carrying the DNA constructs necessary for the exchange of chromosomal fragments mediated by site-specific recombination. The donor and recipient are chosen such that, upon sexual cross or somatic cell fusion, they produce unstable progeny or demonstrate preferential segregation or sorting out. Second, the crossing between donor and recipient species and formation of chromosomal recombinants of donor and recipient plant species is induced. Third, taking advantage of the instability of hybrids between donor and recipient, recombinant cells and plants of the recipient are selected which contain specific chromosome fragments of the donor species. Also disclosed are transgenic plants, libraries and breeding material produced by the methods.

METHOD AND DEVICE FOR COATING SHEETS

Process and device for feeding a coating material onto a moving web (2) under pressure through a feed channel (12). The feed channel (12) extends transversely to the web and has a width corresponding to the web width. It is connected to a pressure equalisation chamber (8) into which the coating material is fed continuously. The amount of coating material fed to the web is adapted to the surface characteristics of the web and the web rate. To achieve this, the volumetric flow from the pressure equalisation chamber (8) is controlled by the feed channel (12), whereas the dry substance concentration of the coating material and the coating width on the web are kept constant. The levelling of the coating on the web is carried out by means of a flexible coating blade (doctor) (16) which, at least at its outlet end, forms an inner side wall of the feed channel. The blade forms an acute angle with the web and adjustment devices (18, 19) are provided for controlling the contact pressure of the blade against the web, both over their entire length and also individually at a plurality of individual points at longitudinal distances on the blade.

METHOD FOR MANUFACTURING COATINGS WITH HIGH ABRASION RESISTANCE

METHOD AND APPARATUS FOR THE CONTINUOUS APPLICATION OF A REGULAR COATING ON A MATERIAL BASKET ON A COUNTER-PART CYLINDER, PARTICULARLY A PAPER OR CARDBOARD

LA MATIERE D'ENDUCTION EST AMENEE SUR LA NAPPE DE MATERIAU 5 SOUS UNE FAIBLE PRESSION A L'AIDE D'UN CYLINDRE D'ENDUCTION 2 ET EST GUIDEE AU MOYEN D'UNE TOLE DE GUIDAGE 8 JUSQU'A LA FENTE D'ENDUCTION 7 FORMEE PAR LE CYLINDRE DE CONTRE-PARTIE ET LE CYLINDRE D'ENDUCTION, APRES QUOI LA MATIERE EST DOSEE PAR UN ELEMENT-DOSEUR 15 ET PARTIELLEMENT DESHYDRATEE DANS LA ZONE D'UNE COUCHE PROCHE DE LA NAPPE EN VUE DE FORMER UNE COUCHE BARRIERE; LE DOSAGE FINAL S'EFFECTUE AU MOYEN D'UN ELEMENT-DOSEUR DEFINITIF 24 SOUS UNE FAIBLE PRESSION D'APPLICATION. CELA PERMET D'OBTENIR, MEME A DES VITESSES DE NAPPE ELEVEES, DE BONNES PROPRIETES CONSTANTES DE L'ENDUIT, MEME LORSQUE LES QUANTITES DE PRODUITS APPLIQUES SONT EXTREMEMENT FAIBLES. APPLICATION : PAR EXEMPLE SUR COUCHAGE DE PAPIER ET DE CARTON. THE COATING MATERIAL IS DELIVERED OVER THE MATERIAL BABY 5 UNDER LOW PRESSURE USING A COATING CYLINDER 2 AND IS GUIDED BY A GUIDANCE SHEET 8 TO THE COATING SLOT 7 FORMED BY THE COUNTERPART CYLINDER AND THE COATING CYLINDER, AFTER WHICH THE MATERIAL IS DOSED BY A MEASURING ELEMENT 15 AND PARTIALLY DEHYDRATED IN THE AREA OF A LAYER CLOSE TO THE TABLECLOTH IN ORDER TO FORM A BARRIER LAYER; THE FINAL DOSAGE SHALL BE CARRIED OUT WITH A DEFINITIVE DOSING ELEMENT 24 UNDER LOW APPLICATION PRESSURE. THIS ALLOWS TO OBTAIN, EVEN AT HIGH TABLE SPEEDS, CONSISTENT GOOD PROPERTIES OF THE COATING, EVEN WHEN THE QUANTITIES OF APPLIED PRODUCTS ARE EXTREMELY LOW. APPLICATION: FOR EXAMPLE ON COATING OF PAPER AND CARDBOARD.
