Abstract: The roll properties of tissue sheets are improved either by imparting cross-machine direction dominant bar-like protrusions to the air side of the tissue by using specially woven transfer fabrics and/or by offsetting recurring surface features of the sheet relative to the surface features of adjacent sheets within the roll, such as by providing a throughdryer fabric with an offset seam. Both techniques provide the resulting tissue sheets with improved capabilities for providing an improved combination of roll bulk and roll firmness.

Abstract: An improved method for imprinting a paper web during a wet pressing event is disclosed which results in asymmetrical protrusions corresponding to the deflection conduits of a deflection member. In one embodiment, differential velocity transfer during a pressing event serves to improve the molding and imprinting of a web with a deflection member. Improved deflection members are also disclosed. Improved tissue webs produced are also disclosed having useful sets of physical and geometrical properties, such as a pattern densified network and a repeating pattern of protrusions having asymmetrical structures.

Abstract: A method of forming a safer and more secure containment for the removal or isolation of harmful and/or noxious particulate materials. The containment is formed using adhesive coated plastic sheeting to form an isolated enclosure. The adhesive holds the sheeting under negative pressure and is removable with minimal damage or transfer to wall and floor surfaces.

Abstract: A web treatment device is disclosed capable of heating and creping a fibrous web with control systems for uniform operation. The web is pressed between two belts in a compression zone, where is it also subject to a temperature gradient that can assist in water removal. Durable coatings on the press belts can assist in maintaining good performance. The system can be used to apply texture to a fibrous web or drive chemical reactions or other physical changes in the web.

Abstract: A method of increasing the wet strength of a creped sheet, which method involves providing a sheet which includes cellulosic fibers, which sheet has a first side and a second side; applying a low temperature-curing latex adhesive binder composition to the first side of the sheet in a fine, spaced-apart pattern occupying from about 20 to about 50 percent of the surface area of the sheet; adhering the first side of the sheet to a creping surface; and creping the sheet from the creping surface. The binder composition is adapted to adhere the sheet to the creping surface and includes a functional group-containing latex, a functional group-reactive crosslinking agent, and a volatile base. In addition, the creping surface is heated at a temperature no greater than about 100° C.

Abstract: A linerless double-backed adhesive tape structure is disclosed. In one embodiment the tape has three tape strips each with an adhesive coated surface and an adhesive free surface. Two of the strips are joined to a center strip along its lateral edges with the adhesive coated surfaces of the two strips overlapping and adhered to the adhesive coated surface of the center strip. Also disclosed is a method of unitizing and sealing a plurality of containers. In one embodiment a double-backed adhesive tape structure is adhered to each of the containers and the containers are stacked together with the exposed adhesive side of the tape on each container adhered to the exposed adhesive side of the tape on an adjacent container. Finally, an apparatus for dispensing the double-backed adhesive tape of the present invention is disclosed.

Abstract: A machine operative to sequentially pull jacketed flexible magnetic disk units (which may be termed "diskettes") into a data transferring position, close a collet on a disk driving spindle for clamping the disk onto the spindle for drivingly rotating the disk from the spindle and move magnetic heads into contact with the disk for a data transferring action. The machine includes a clothespin like picker or gripping device reciprocative so as to move into embracing relationship with the diskette and to then pull the diskette into data transferring position. The diskettes are contained in a magazine which is translatable transversely with respect to the path of travel of the picker device so that the picker device may be operative to grip any one of the series of diskettes, depending on the translated position of the magazine.

Abstract: A magazine particularly for jacketed magnetic disks (which may be termed "diskettes") of the type disclosed in U.S. Pat. No. 3,668,658 and a lid fitting on a forward, sometimes open, end of the magazine. The lid has internal ribs for supporting weak side edges of the diskettes in the magazine particularly when the magazine is turned on its side, and the magazine has aligned internal bottom and top diskette supporting ribs. A swing connection is provided between the lid and the magazine adjacent the top of the magazine including L-shaped slots formed in side panels of the magazine extending from the forward edges thereof horizontally and then upwardly and a pair of pins carried by the lid and fitting in the L-shaped slots. The lid when placed on the magazine thus first moves horizontally but slanting forwardly and downwardly to first move the upper ends of its internal ribs between the diskettes and then upwardly and in swinging movement to close the magazine.
