Abstract: Devices and methods for shotshell cartridges, particularly shotshell cartridges with biodegradable components. One or more of the casing, shot wad, spacer, and powder wad may be formed of biodegradable materials. A biodegradable shot wad is manufactured of cellulosic fibers and wax to provide obturation and gas seal properties at high pressures with high reliability.

Abstract: An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.

Abstract: Driveshaft dampers are provided for use in driveshafts to dampen or attenuate aspects of noise, vibration, and harshness (NVH). Systems and methods for making and using driveshaft dampers are further provided. The driveshaft dampers may be made using a helical-winding process and include attenuation strips with elongate protrusions. Various embodiments of helically-wound driveshaft dampers include a core and one or more attenuation strips helically wound around the core.

Abstract: Writing implements, such as ballpoint pens and mechanical pencils, and method of making such writing implements, having a body made of recycled newspaper are disclosed. The writing implement's body, often referred to as a barrel, may be decorated, shaped, scented or have other desirable features.

Abstract: An improved method of manufacturing support posts that are commonly formed from wound paper tubes. With this invention, a number of material layers are laminated together and formed in a continuous manner while they are still pliable. Materials are taken from a number of rolls that is equal to the number of layers required within the finished product. The individual layers are drawn through a glue station where adhesive is applied between each layer. The finished shape is created by bringing together all of the layers, then progressively folding them around a heated mandrel that has been shaped to match the inner hollow space of a formed paper tube corner post design.

Abstract: An adjustable sleeve is disclosed that employs a pivot region which allows rotation of the first end of the sleeve relative to the second end of the sleeve. Rotation about the pivot region allows the sleeve size to adapt to many different sizes and tapers of containers. Rotation results in increasing a diameter of the top of the sleeve and decreasing a diameter of the bottom of the sleeve, and vice versa.

Abstract: A winding core for nonwoven fabrics and the like comprises a wound paperboard tube comprising a plurality of paperboard layers wound one upon another about an axis of the tube and adhered together, and regions of grit bound in an adhesive binder, the regions being affixed to the outer surface of the tube and being sized and arranged such that the regions collectively occupy a minority of the total surface area of the outer surface, the regions further being arranged such that there are at least two of the regions axially spaced apart along a length of the tube in positions to simultaneously encounter and snag an end of a fabric web to be wound about the core. In one embodiment, a narrow sandpaper strip is helically wound about and affixed to the tube to form the regions of grit.

Abstract: A valve bag has a sleeve that includes a butt seam formed by abutting opposed edges of a paper sheet and securing the abutting edges. A strip of tape may be used to secure the abutting edges. The interior surface of the sleeve and the tape are both constructed from a sealable material. A tight seal is achieved when the sleeve is sealed.

Abstract: A composite container includes a high barrier inner liner member including a metal layer of vacuum-deposited aluminum parallel with and spaced from the longitudinal edge of a synthetic plastic base thereby to define a first web that is helically wound in edge-overlapping relation such that one longitudinal edge of the metal strip overlaps the other longitudinal edge of the metal strip by a given distance (d). The overlapping edges of the first web are hermetically joined by a heat-sealable bond between an adhesive layer covering the metal strip and the adjacent face of the first web, and a compatible heat-sealable layer on the opposite face of the web.

Abstract: Apparatus for receiving a strip of flexible bags with capped spouts at longitudinally spaced intervals which are to be separated at transverse joints and then fed individually to a point of use. It includes draw rolls for drawing the strip horizontally into cooperation with a separator, means for vertically reciprocating the separator to pass through the strip and separate the leading bag therefrom, a guide channel for receiving the spout of each separated bag, and a feeding element for engaging the spout on each successive bag and arranging the spouts in predetermined spaced relationship relative to previously inserted spouts and with the leading bag in a selected position for its spout to be engaged by bag-withdrawing means.
