Abstract: In a process involving at least two film-shaped substrates (44, 46) bonded together by means of at least one adhesive layer containing a catalyst which accelerates hardening of the adhesive, a first substrate (44) is coated with a liquid film comprising three layers viz., two adhesive layers (34, 38) and an intermediate layer (36), which is situated between the adhesive layers (34, 38) and contains a catalyst (37), using liquid film coating in the form of curtain coating or slide-coating and subsequently bonded onto the second substrate (46). The laminate (48) formed may be coated via at least one liquid film coating with a further three layer liquid film comprising two adhesive layers (134, 138) and an intermediate layer (136), which is situated between the adhesive layers (134, 138) and contains a catalyst (137), using curtain coating or slide-coating and subsequently bonded onto at least one additional substrate (50) to form an additional laminate (52).

Abstract: In a method of and apparatus for manufacturing a filtering screen, a frame of plastics coated metal or reinforced plastics material is located in a jig and at least two sheets of wire cloths are placed over the frame and their edges gripped by pneumatically operated clamps carried by the jig. The clamps are pneumatically driven outwardly of the frame to tension each cloth in orthogonal directions. The tensioned cloths are pressed against the frame and heated in order to bond the cloths to the frame. The heated material is allowed to cool, and after completion of the bonding step the clamps are released, allowing the frame to be removed from the jig. Where necessary the cloths are trimmed back to the edges of the frame. A separate set of pneumatically operated clamps may be provided for gripping all four edges of each wire cloth layer to allow each layer to be individually tensioned.
Abstract: A method of forming an overlapping section involves radiating a plasma onto a first overlapping part of a first workpiece, over which oil is spread. Thereafter, silicone rubber, which functions as an adhesive and a sealant material, is applied onto the first overlapping part, and a second overlapping part of a second workpiece is overlapped on the first overlapping part. When the components are left standing still for a predetermined period of time, the overlapping section is formed, in which the first overlapping part and the second overlapping part are adhered to one another.
Abstract: Tooling aids for applying pressure in laminating, and methods for their use, are described herein. In one embodiment, a caul for applying pressure in laminating includes a base portion positioned between first and second corner portions. The base portion can have a curved shape when it is in a relaxed state, but it moves to a flatter shape when subjected to pressure during lamination. Movement of the base portion to the flatter shape causes the first and second corner portions to move outwardly and away from the base portion. In this manner, the caul can be used to compact laminating materials into corner regions of a corresponding female mold surface.
Abstract: A multi-microlayer thermoplastic film structure and methods of making the same. More specifically, this invention relates to a multi-microlayer film having a corrugated polymer layer and a thermoplastic elastomer layer. Filler materials may be included in either the corrugated polymer layer or the thermoplastic elastomer layer. The multi-microlayer films may be formed in a co-extrusion process.
Abstract: Disclosed is a fibrous web which includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.

Abstract: A method is provided for attaching together a larger tube and a smaller tube in a T-shaped intersecting joint. A hole is formed in the larger tube with a flange surrounding the hole. A circumferential extending flange is formed on the outside of the smaller tube. Adhesive is placed on either the outside of the smaller tube or the inside of the flange of the larger tube. The smaller tube is inserted into the hole in the larger tube so that the adhesive is interposed between the inside of the flange of the larger tube and the outside of the smaller tube and the flange on the outside of the smaller tube comes into electrical conducting contact with the flange of the larger tube. Electrical current is applied to flow between the large tube and the small tube so that electrical resistance heating is obtained to cure the adhesive.

Abstract: The invention is a method for application of a special low viscosity cyanoacrylate adhesive which is used for the manufacture and repair of wooden furniture. The cyanoacrylate adhesive quickly penetrates and bonds wood to wood. The wooden furniture that results from the process of this invention are cohesive in structure and are ready for immediate use. This special wood grade cyanoacrylate adhesive provided by this invention permits those in the furniture repair or furniture manufacture industries with a method of repairing or assembling wooden furniture in an easy and quick manner.
Abstract: A method and device allows dynamic mask welding with online position adjustment in the high-speed welding of structured and endless plastic films. By a transparent driven mask roller provided with masks being arranged in a passive pressure roller surrounding the mask roller, detection can take place optically, and the mask roller and consequently the mask are synchronized with the film speed. Adjustment is detached from a film transport mechanism and does not influence the welding process and in this case, above all, the speed. High film transport speeds in the range of up to 1000 mm per second can be employed.

The insulation is readily applied to a reusable launch vehicle via a silicone adhesive.
Abstract: This present invention relates to a process of liquid crystal panel with one drop fill (ODF). A black matrix, which can not be penetrated by an ultraviolet light while curing a sealant, is formed on the other substrate. Hence, in this present invention, it can avoid the aforementioned problem during the curing process and simplifies the curing process.
Abstract: A method of forming a multilayer insulation material formed of an acoustical composite layer and a first thermal layer is provided. The acoustical and insulting layer is formed of a polymer based thermoplastic material and reinforcing fibers. Preferably the reinforcing fibers are wet use chopped strand glass fibers (WUCS). The acoustical composite layer may be formed by opening the WUCS fibers, blending the reinforcement and polymer fibers, forming the reinforcement and polymer fibers into a sheet, and then bonding the sheet. A first thermal layer formed of one or more polymer based thermoplastic organic materials is then positioned on a first major surface of the acoustical composite layer. A second thermal layer of polymeric fibers may be optionally positioned on a second major surface of the acoustical composite layer. The multilayer acoustic material may be utilized in semi-structural and acoustical applications.
