Inventor: SACHS HANS IMMO
IPC: C08G18/64
Filed: 1987-02-25
Abstract: This invention relates to formaldehyde-free, aqueous glue dispersions which contain polyisocyanates. These systems are particularly suitable for gluing veneers and surface materials on wood and wood products. The systems are prepared from polyisocyanates in combination with extenders based on flours and cold water-soluble of hydrolyzed natural starch. In this process, polyisocyanates or aqueous dispersions thereof are added while stirring to aqueous solutions or mixtures of starch and flour. The extender-containing adhesive systems are aqueous glue dispersions having increased service life which in their preferred embodiment contain about 15 to 30% by weight of polyisocyanates, preferably polyphenyl-polymethylene polyisocyanate (PMDI), 10 to 15% by weight of starch which is soluble in cold water and 14 to 25% by weight of (cereal) flour and optionally, other additives and the appropriate quantity of water adding up to 100% by weight. The glue dispersions are easily applied with glue spreading machines and if applied in suitable quantities do not bleed through veneers. The implements used for applying the glues can easily be cleaned by rinsing them with water. The invention is also directed to the use of the glue dispersions for gluing, particularly for gluing veneers or other surface coating materials to wood or wood products.

Title: Laminated integrally woven papermaker's fabric.
Inventor: FARGEOUT PATRICK
IPC: B32B5/26
Filed: 1997-08-28
Abstract: A laminated integrally woven on-machine-seamable papermaker's fabric includes two single-layer woven fabric plies sharing a common machine-direction (MD) yarn. The common MD yarn, which is the weft yarn on the loom during the weaving of the fabric by a modified endless weaving technique, forms seaming loops which join the plies to one another at the ends thereof. The fabric may be needled with a batt of staple fiber material. During the weaving of the press fabric, solvent-removable binder yarns join the two plies, which are accordingly integrally woven. When the weaving is completed, the solvent-removable binder yarns are removed through dissolution with an appropriate solvent, yielding the laminated structure. A batt of staple fiber material may be needled into and through the laminated structure. The papermaker's fabric may be used as a forming, press or dryer fabric, or as a base for a polymer-coated, paper industry process belt, such as a long nip press, sheet-transfer or calender belt.

Title: Handover in a mobile communication system
Inventor: KANERVA MIKKO
IPC: H04W28/04
Filed: 1998-02-16
Abstract: The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of neighbouring base stations (BTS) at a receiver of a mobile station (MS), comparing the measurement results thus obtained and other variables of the connection with handover criteria, and performing a handover from the source cell to the target cell, when the pre-set handover criteria are met. The method of the invention is characterized by determining at least one error connection possible for the connection in a potential target cell for the handover, determining at least one handover criterion on the basis of the determined error correction of the potential target cell, and setting the error correction of the connection in the target cell (BTS2) as said error correction of the base station of the target cell. The invention further relates to a mobile communication system for performing handover.

Title: Method and apparatus for producing spun yarn characteristics in synthetic multi-filament yarns
IPC: D02J3/02
Filed: 1979-12-18
Granted: 1983-03-23
Abstract: A method and apparatus is provided for producing a synthetic multifilament yarn having appearance, bulk and hand characteristics of conventional spun yarns of staple fibers while retaining strength characteristics of continuous filament yarns. The multifilament yarn is air jet textured to form loops, bows, coils and the like in at least the surface filaments thereof and at least some of these loops, bows, coils and the like only in the surface filaments are parted while the interior or core filaments remain substantially intact to form a yarn having free filament or fiber ends projecting from a substantially continuous filament core. The interior or core filaments are shielded or protected from being parted by false twisting the yarn (without heat setting the twist therein) to provide a substantially closed form with the interior or core filaments surrounded by the surface filaments and by parting the surface filaments while the yarn has twist therein. Also, other steps are taken and means are provided for limiting the filament parting action solely to the surface filaments. Finally, the yarn is heat set after the filaments are parted and after the twist is removed to fix the characteristics imparted in the previous processing steps therein.
