Abstract: The strength of composite patches is improved over conventional bolted or bonded patches by including Z-pins in the patch/parent structure interface to provide a mechanical link with small stress concentration between the patch and the parent structure. In some cases, we achieve a stronger repair removing the pins to leave holes that fill with resin from the patch during the curing or bonding operation.

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 cloth-like microporous laminate of a nonwoven fibrous web and thermoplastic film is made by lamination of a microporous-formable film composition and a nonwoven fibrous web followed by incremental stretching to form the cloth-like microporous laminate. The cloth-like microporous laminate has air and moisture vapor permeabilities, but acts as a barrier to the passage of liquids. The cloth-like laminates are especially useful in fabricating garments in order to provide the breathable qualities of air and moisture vapor transmission with liquid-barrier properties. Such garments include baby diapers, baby training pants, catamenial pads and garments, and the like where moisture vapor and air transmission properties, as well as fluid barrier properties, are needed.

Abstract: A method and apparatus for sealing a container with a cap and a seal member which is adhered to the neck. The seal member is inserted into the cap before the cap is applied to the neck by moving the cap in an axially downward direction relative to the neck to substantially seat the cap on the neck so that the cap cannot be removed without unscrewing the cap. The seal member is firmly held against the neck by the cap while the seal disc is adhered to the neck. In one modification, a pressure application applies a downward directed force to urge the cap against the neck while the seal disc is adhered to the neck. In another modification, the cap is tightened onto the neck at a fine adjustment station to eliminate gaps between the underside of the cap and the neck before the seal disc is adhered to the neck.

Abstract: The present invention relates to a method of making a laminated product, such as an insulator pad comprised of foam and stiffening layers held together with adhesive. A thin protective barrier foam sheet is placed between the surface of a compression roller and the sheets to be laminated together by passing them between compression rollers. The thin protective barrier foam sheet may or may not form the outer layer of the laminated product and prevents adhesive and foam material from contaminating the surface of the roller.

Abstract: A direct extrusion process for manufacturing conductive polymer articles of manufacture employs a twin screw compounding extruder that compounds a polymeric mixture from materials received, in predetermined proportions, from gravimetric feeders, then extrudes a compounded conductive polymeric material in the melt phase. The extrudate is then fed into a gear pump that allows the extruder to discharge the compounded material, while it is still in the melt stage, at a relatively low pressure. The gear pump produces a substantially constant volumetric output of the compounded "melt phase" material at sufficiently high pressure for delivery into a sheet die. The sheet die forms the compounded material, while still in the melt phase, into a continuous web.

Abstract: A breathable, comfortable, elastic pressure sensitive, permanent tacky, adhesive bandaging material is disclosed. The material includes a fabric formed of stretch and non-stretch filling and warp yarns which are coated with a release agent, a stiffening agent, and an adhesive material. Both the agents and adhesive material are applied to the backside of the fabric, with a small amount of the release agent being absorbed through the fabric to the face surface thereof. The adhesive material may include a solvent which tends to plasticize the stiffening agent to a small degree when applied thereto. The resulting bandaging material exhibits characteristics of good tearability along with a relatively soft face surface and an improved hand. The material is manufactured by applying the agents and adhesive to the fabric when the fabric is in a relaxed state. When subsequently stretched, the adhesive is pulled into a random, nonuniform and discontinuous layer.

Abstract: A disposable absorbent article or pad provides improved wearer comfort because it is shaped to provide an optimal fit to the user's undergarment, it has soft, flexible sides to prevent chafing of the user's thighs, and it has relatively stiff ends to prevent the ends from curling up during use. The difference in flexibility between the pad's ends and sides is achieved by placing a core of absorbent material end to end along the longitudinal axis of the product and centered in the midsection of the product so that the absorbent material is present in the peripheral sections of the product's ends but is absent in the peripheral sections of the product's sides.

The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position.

Abstract: An apparatus for production of a three-dimensional fabric including laminated fiber layers having a fiber arranged along axial lines and a connection yarn inserted into the fiber layers to connect the fiber layers with each other are described. The fiber layers are formed by arranging the fiber while folding the fiber back along the axial lines. The laminated fiber layers are formed by arranging the fiber along axial lines, by engaging the fiber to a plurality of restriction members located with a predetermined pitch on a frame so as to surround an area where the connection fiber is inserted into the fiber layers, and then folding the fiber back along the axial lines. A plurality of yarn inserting needles arranged in a series together with the connection fiber are simultaneously thrust into the fiber layers until a holding section of each yarn inserting needle projects outside of the fiber layers to make a loop of the connection yarn at each holding section.

Abstract: A flexible liner is formed from a resilient material and includes a back side surface having a number of outwardly projecting members that extend a distance away from the liner. The flexible liner is in sheet form for rehabilitating surface sections, and is not in the form of a tube to cover an entire surface diameter. The outwardly projecting members each have a head enlarged profile configured to provide a strong mechanical lock with a carrier that is injected within an annular space disposed between the liner back side surface and the underlying substrate surface in need of surfacing or rehabilitation. The liner is positioned adjacent the structure surface by use of a collapsible, expandable form, and a carrier is injected within the annular space disposed therebetween so that the liner outwardly projecting members are completely enveloped by the carrier. The carrier is cured to form a mechanical lock between the outwardly projecting members and the carrier.
