A sports ball comprising a transparent outer wall surrounding a hollow cavity and defining a geometric center, and a central core object suspended at the geometric center of the hollow cavity. The ball may have the shape of a sphere having a center point, with the central core object suspended at the center point of the sphere. In other cases, the ball may be oblong or ellipsoid, with the central core object suspended at the center points of the respective major and minor axes of the ellipsoid. The transparent outer wall of the ball may be elastically deformable, and may be comprised of a transparent inflatable bladder contiguous with an inner surface of a transparent outer skin. The transparent outer skin may be comprised of a plurality of outer facets joined together, such as by sewing.

A cushioning article comprises a first and a second polymeric sheet bonded to one another and enclosing an interior cavity. The polymeric sheets retain a gas in the interior cavity. A tensile component disposed in the interior cavity includes a first tensile layer, a second tensile layer, and a plurality of tethers spanning the interior cavity and connecting the first tensile layer to the second tensile layer. An inwardly-protruding bond joins the first polymeric sheet to the first tensile layer, protrudes inward from the first polymeric sheet toward the second polymeric sheet, and partially traverses the plurality of tethers. The first polymeric sheet is displaced from the first tensile layer adjacent to the inwardly-protruding bond by the gas. A method of manufacturing a cushioning article is disclosed.

An add-on part (10) for connecting to a component (30). The add-on part (10) has a longitudinal axis (A) and a welding section (11) to be welded to the component (30) by torsional ultrasonic welding. The welding section (11) has a contact surface (12) for contact with a torsion sonotrode (70) and a welding surface (13) for connecting to the component (30). The welding section (11) is delimited, at least in some sections, by an inner vibration-decoupling zone (14). The inner vibration-decoupling zone (14) extends, at least in some sections, at an inclination to or parallel to the longitudinal axis (A). The method comprises a) bringing the welding surface (13) in contact with a welding region (31), b) applying a force to the contact surface (12) such that the welding surface (13) is pressed against the welding region (31), and c) introducing a torsional ultrasonic vibration into the welding section.

Methods of making labels devoid of liner plies. A method of making a label for securement to a substrate comprises providing a face ply having a top side and a bottom side. The method includes disposing a hotmelt adhesive on the bottom side in a pattern. The method comprises formulating a liner coating configured to be activated by a fluid. The method includes disposing the liner coating on the bottom side outwardly adjacent the hotmelt adhesive. The bottom side is configured to be secured to a substrate via the hotmelt adhesive upon activation of the liner coating by the fluid.

A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.

Method for the production of a pacifier teat and pacifier teat with a suction section forming a cavity, to which suction section a shaft adjoins, wherein an elastic hollow body having suction section and the shaft is pre-formed in an injection or in a dipping process and opposite wall sections of the pre-formed hollow body are connected with each other in the region of the shaft.

An article of manufacture that has at least three layers of sealable material. There is at least one first seal between at least two of the layers in a first area having a first sealing affinity effected at a first sealing parameter. There is also at least one second seal between at least two more layers, where at least one of these two layers is distinct from the at least two layers joined by the first seal, in a second area having a second sealing affinity effected at a second sealing parameter, where the second sealing parameter is different than the first sealing parameter, thereby allowing for sealing of discrete areas of the article in discrete steps.

Plate packs are produced from a sheet-like starting product (1), which is cut to form plates, which are stacked to form a plate pack. The plates within the plate stack are joined to one another by a bonding agent. The bonding agent used is a cyanoacrylate adhesive with a high temperature stability rating. It is applied to a wetting layer (14) for the adhesive. The wetting layer (14) is formulated to a pH in a region >7. The cyanoacrylate adhesive with a high temperature stability rating is able to spread on the wetting layer (14) such that effective wetting takes place, thus achieving quick and secure joining of the plates to one another.

The first polymeric sheet is displaced from the first tensile layer adjacent to the inwardly-protruding bond by the gas. A method of manufacturing a cushioning article is disclosed.

An airtight bladder for kites and method of sealing an airtight bladder for kites. The bladder body has longitudinal edges sealed with a lap seam and ends sealed by a combination of deforming bladder material and applying an end seam. The deforming of the bladder materials is done by folding, rolling, accordion folding, knotting, or twisting the ends. The deforming of the bladder material in this matter shelters and protects the end seals.
