Abstract: A procedure for lining spaces with high temperatures, in which the surfaces of the space are lined with fibrous lining material in which the fibers are mainly parallel with planes at right angles against the surface of the space. In the procedure, loose, separate, plate-like fiber strips (1) are used which are disposed side-by-side relative to each other in an installation position to form a transport/application package (2). A fixing compound (3) is applied as a layer upon the edges of the side-by-side strips advantageously over the whole area of one strip layer (4) of the transport/application package. From the package is taken a suitable bunch of strips treated with fixing compound, this bunch being pressed onto the surface of the space at the point of installation and compressed to suitable compactness.

Abstract: A method of repairing an area of metallization that has lifted from a circuit board substrate uses a dry film epoxy placed between the lifted metallization and the substrate. Downward pressure and heat are simultaneously applied to the lifted area to rebond it to the substrate. Both metallization pads and traces may be repaired with the method, and the resulting bond may be stronger than that originally present. When heated, the dry film epoxy will melt and cure very quickly, requiring no further processing. The method is particularly useful when repairing circuit boards intended for microwave circuitry, in which conductive ribbons are gap welded to metallization pads. A metallization pad repair operation may be combined with a ribbon attachment operation, accomplishing both with one gap welding operation. The gap welder provides the downward force and heat necessary to bond the ribbon and repair the lifted pad.

Abstract: A 0.005-0.020 inch thick thermoplastic sheet containing 20-80 weight percent metal alloy biocide particulate, such as 50 micron copper powder, protects submarine structures from adhesion of flora and fauna. The sheet is isotropic and inelastically deformable in the plane of the sheet. The sheet is heated to form and adhere it to the ship hulls and the like. An intermediate lower melting point film and other aids are employed in the adhering step. Heating of the sheet prior to the adhering process minimizes liberation of environmentally harmful volatiles. The sheet is removable by heating, so the material may be recycled.

Abstract: A panel assembly and method for manufacturing the panel assembly, especially adapted for use in vehicles, includes a panel of predetermined size and geometry wherein a surface of the panel to receive a gasket is primed using a material especially adapted to prepare the panel surface to bond with the gasket. The desired gasket profile is molded separately from the panel from a polymeric material. Following formation of the gasket, the panel is located thereon and pressed into intimate contact with the gasket for a prescribed period of time. The panel and attached panel are removed as an assembly. Additional or optional steps may be followed including preheating the panel and primed surface prior to bonding to shorten the cycle time and improve adhesion. Moreover, heat may be applied to the contact boundary between the panel and gasket substantially simultaneously with the application of pressure. The steps of heating and applying pressure may be repeated to insure proper adhesion.

Abstract: The machine of the present invention manufactures low-cost garments out of two plys of web material, preferably nonwoven material. It includes a pair of feeder mechanisms to supply two separate sheets of the web material through cutter mechanisms where the webs are cut into shapes suitable for the desired garment. The shapes of one sheet are larger than the shapes of the other sheet. The sheet with the larger shape is placed on a carrier, and the sheet with the smaller shape is placed thereupon. As the combined sheets are moved by the carrier, a plurality of folding mechanisms turns the edges of the larger sheet around the edges of the smaller sheet to create a seam which is subsequently secured, as by adhesives or sewing. The carrier may be either a rotating cylinder or it may move longitudinally. The seams may be created along machine direction lines, cross machine direction lines, or along lines at acute angles to either the direction of movement or perpendicular thereto.

Abstract: An environmentally sound vegetation growth-enhancing erosion control blanket is formed from an elongated rectangular excelsior/wood wool mat. The mat is held together with adhesive and a surface pattern is embossed therein. When the finished blanket is placed atop the ground, the blanket serves to shield the earth area from wind and water erosion forces, without the presence of the plastic netting often used in the prior art. As the ground vegetation grows, it ultimately replaces the blanket which decomposes and furnishes the ground vegetation with a nutritive mulch.

Abstract: A constant-flow drip irrigation tape hose includes a primary flow path communicating water along the length of the hose. A secondary drip-flow path leads from the primary flow path to an emitter site outwardly of the hose. The hose is formed with a pair of variably spaced apart walls at least one of which is formed with a continuously-open channel defining part of the secondary flow path. A second variable-area part of the secondary flow path is defined by radial spacing of the pair of walls from one another. At least one of the pair of walls is responsive to internal water pressure in the primary flow path to open and close the variable-area part of the secondary flow path in response, respectively, to decreasing and increasing water pressure in the hose. A plurality of emitter sites are spaced regularly along a length of the hose.

Abstract: A method of applying a film, preferably of PET, to a surface, preferably the front surface of the panel of a CRT. Resin is first applied to the surface in a predetermined pattern. The film is then pressed against a part of the surface near one edge of it by a roller. The roller is then moved across the surface to press the film onto the resin. The pressure exerted by the roller is reduced in the middle of the surface as compared with that exerted at the edge. Two different pressures may be used in the middle part.

Abstract: A unique clip for holding moldings or other items to a base surface includes bearing surfaces which are spaced laterally inwardly from outermost edges of an underlying substrate. Due to the inward position of the bearing surfaces, a force transferred to the bearing surfaces will be a plucking force rather than a peeling force as may have occurred with the prior art. In other features of this invention, the clip is formed with non-planar support structure for unusually wide applications. Further, in a method of utilizing the inventive clip, a single backing cover is placed over the adhesive strips of several spaced clips. Thus, an assembler need only remove one cover, and then place the molding on the body of a vehicle.

Abstract: A latex balloon neck is pretreated by refreshing a region (18) of the inner surface (16) of the neck. The refreshed region extends substantially entirely around the inner circumference of the neck. The refreshing consists of cleaning the latex surface with a solvent e.g. isopropanol. The balloon neck is sealed by pressing (e.g. pinching and/or stretching) opposed areas of the refreshed surface (18) into direct contact with each other to form a latex-latex bond without requiring any additional adhesive coating. A removable protective tape (20) is placed over the refreshed region (18) to prevent the refreshed region from losing its bonding quality. An apparatus/method for preparing such balloons, and an apparatus/method for inflating and sealing the balloons (automatically) are also described.
