  • Patent number: 4427541
    Abstract: Fractionation apparatus (20) is disclosed which utilizes a rapidily rotating disk which receives a liquid suspension of particles to be separated onto its rotating face surface (35). When the film of liquid and particles on the rotating face surface (35) reaches the peripheral edge (38) of the face, particles above a certain size are radially ejected while smaller particles and the liquid are carried over the edge onto the surface of a depending rim (39). The suspension of smaller particles and liquid is carried down the rim to the rim edge (40) at which point the smaller particles and liquid are disengaged. A separator wall (27) may be interposed between the two streams of particles emanating from the disk (24) to provide a physical separation of the larger and smaller particles once they have left the disk.

  • Patent number: 4285461
    Abstract: A container having a tray portion and a cover sealed to the peripheral top edges of the tray. Cut score lines on the inner side of the cover provide a splitting of the paperboard of the cover upon opening to allow the cover to be peeled from the tray to a hinge at the back edge of the tray. Offset double cut score lines may be provided on the upper and lower sides of the cover at the front edge of the tray, which will split upon opening of the cover to yield overlapping locking flaps which can be used to reclose the cover. Flanges may be attached to the lateral side edges of a paperboard tray by cut score hinges, and adhered to the inner side of the cover to provide layer separation of the flanges upon opening rather than layer separation of the cover. Alternatively, double cut score lines can be formed along the lateral sides of the cover in positon to register with lateral side flanges on the tray, which split and provide overlapping locking flaps when the cover is opened.

  • Patent number: 4252052
    Abstract: Method and apparatus for forming a sealed pouch from a paperboard blank having a heat activatable sealing material on a surface thereof. Blanks are received in an initial position above opposed curved forming surfaces and underneath a reciprocating mandrel, with the blank being folded about the mandrel as the mandrel drives the blank in a longitudinal direction between the forming surfaces. Application of heated air activates the heat sealable material, and folding plates fold the longitudinal edges of the blank inwardly to a position where clamping bars can clamp the longitudinal edges together to complete the heat seal. The folding plates and clamping bars withdraw after the heat seal is completed, and the formed pouch is ejected from the mandrel which thereafter reciprocates to its initial position to allow another blank to be inserted above the forming surfaces.

  • Patent number: 4247349
    Abstract: Panels of plastic film are delivered to a perforated vacuum drum which has a knife edged die mounted on its surface. Each panel is laid over the die and rotates with the drum into rolling contact with an anvil roll which firmly presses the film panel against the knife edge to cut the panel. After cutting, the film panel continues to rotate with the drum to a position wherein it registers with a blank having a cut-out opening therein which is covered by the film panel. The areas of the blank surrounding the cut-out opening are covered with an adhesive material which causes the film panel to remain adhered to the blank. The vacuum drum continues to rotate and, after bonding of the panel to the blank, the drum releases the vacuum draw on the panel. The cuts formed in the plastic film panels can be straight lines, lines of perforations, or cut-outs bounding areas which are removed from the panel.

  • Patent number: 4164595
    Abstract: A premoistened wiper having high initial wet strength in a wetting liquid, and lower wet strength when immersed in substantially neutral water to allow for flushability. The wiper includes a nonwoven web of fibrous material which is bonded together by a polymeric adhesive binder, with the bonded web being moistened until the time of use by a wetting liquid having an acid pH level which is safe for external use on the human body. The binder is composed of a material which is highly adhesive in an acid pH liquid to bind the fibers of the web together, and which is further resistant to weakening over the relatively long periods of shelf life of the wiper. However, the binder loses its binding strength in substantially neutral or alkaline flush water to allow for flushability. The bonded wiper is maintained with wetting liquid thereon within a moisture sealed container until the time of use, and readily loses strength and disintegrates when disposed of in the substantially neutral water of a sewer system.
