Abstract: PCT No. PCT/DK91/00090 Sec. 371 Date Oct. 14, 1992 Sec. 102(e) Date Oct. 14, 1992 PCT Filed Mar. 21, 1991 PCT Pub. No. WO91/14819 PCT Pub. Date Oct. 3, 1991.Good deinking of waste paper can be obtained at high consistency by first pulping at high pH, then lowering the pH, adding alkaline cellulase and letting the cellulase act during continued pulping and/or maceration. The improved deinking results in higher whiteness and better cleanliness (fewer ink particles) in paper made from the treated pulp after separation of ink particles. This cellulase treatment results in better operation of certain equipment such as thickeners and in better drainage of the pulp during paper making.

Abstract: Cette invention consiste à effectuer les opérations de préparation et de traçage d'une image à gradation, telle qu'une photographie, et d'une image sans gradation introduites dans un organe de traitement d'images (13) et à former, sur la base d'un fichier de données, au moyen d'un organe de formation d'images (18), une couche réceptrice de colorant (21) dans une région de formation d'images à gradation d'un support (26). Une image à gradation (22) est formée dans la couche réceptrice de colorant par un procédé de transfert thermique et une image sans gradation (23), par exemple un ensemble de caractères, combinée avec l'image à gradation est imprimée avant ou après la formation de l'image à gradation. Une couche protectrice (24) est en outre formée sur l'image à gradation (22) et, si nécessaire, sur l'image sans gradation (23) au moyen d'un organe de transfert de couche protectrice incorporé dans l'organe de formation d'images (18), ce qui permet de produire des cartes, par exemple des cartes de visite commerciales, comportant une photographie, ainsi que des documents tels que des passeports. On peut former les images à gradation et sans gradation sur un papier ordinaire, sans endommager sa texture et sa capacité à recevoir des caractères d'écriture, en formant la région de la couche réceptrice uniquement dans la partie de la région comportant l'image à gradation. En utilisant des feuilles réceptrices d'images à transfert thermique pourvues d'un motif (tel qu'une teinte de base), on peut également former le fond d'une image, par exemple en teinte de base, tout en empêchant les falsifications et les altérations de ces cartes et documents.

Title: Stackable packing for bulk material.
Inventor: KUEPPERSBUSCH GERD
IPC: B65D77/06
Filed: 1991-06-21
Abstract: A stackable bulk-material packing or container is disclosed, which can have a simple opening for pouring out the contents. The packing uses a folding-box carton with a bag inside it. The bag has an opening for pouring out the contents. The opening has an annular shoulder and is located behind a removable section of the carton. Removal of this section produces an opening in the carton giving access to the opening in the bag. The removal section of the carton is located at one of the upper corners or one of the upper edges of the carton. Because the removable section of the carton and the opening in the bag are co-located at one of the upper corners or one of the upper edges of the carton, the contents do not exert any pressure on them, and the closure can thus be of a simple design.

Abstract: An integrated gladhand and quick-release valve (10) for tractor-trailer highway vehicles is mounted on the tractor (14), as opposed to the trailer (30), so the operator of a particular tractor will uniformly have quick-release capability for any trailer drawn by the truck (14). The integrated gladhand and quick-release valve (10) provides an inlet port (29) for fluid communication from the tractor brake system and an outlet port (31) for fluid communication to the trailer brake system. The intermediate passageway (33) that provides fluid communication between the inlet (29) and outlet ports (31) contains a valve element (35). The valve element (35) may be apertured (37) to allow limited, continuous fluid communication between the tractor and trailer brake lines. During the quick-release mode, the tractor side is substantially isolated and the trailer side is vented through an exhaust port (41). The present invention provides a uniform and safe braking system for tractor-trailer highway vehicles where the tractor operator does not own or maintain the trailers. The present invention provides an improved integrated gladhand and quick-release valve (10) that reduces the response time of trailer brakes to application and release of the brake pedal and reduces hysteresis effects.
