Abstract: This invention relates to the discovery that the perceived softness of embossed tissue can be increased greatly while avoiding prior art nesting problems if a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike debossments with deeper more sharply defined signature debossments. The stitchlike debossments are rounded and arranged in wavy flowing intersecting lines. The signature debossments are arranged in regions framed by the intersecting wavy flowing lines.

Abstract: A self-limiting dispersion of a conductive material in a binder is disclosed wherein the conductive material consists essentially of a carbon material having a structure selected to undergo percolation when dispersed in the binder at a concentration of from about 10 weight percent to about 45 weight percent. The binder comprises a thermoplastic material selected to go through a first order phase transition or a second order transition at a temperature from about 300.degree. F. to about 480.degree. F. and the dispersion is formulated near the conductance percolation threshold so that its electrical conductivity drops precipitously (e.g., at least about 1.5 orders of magnitude) above the binder transition temperature. The dispersion of the conductive material in the binder is especially suitable for use as a self-limiting microwave heater material which is either a molding composition, or surface coating composition, and especially a composition that can be applied to a substrate by printing.

Abstract: A receptacle includes pairs of opposed side panels which are connected by connector flaps. The connector flaps have two relatively movable flap portions and the flap portions cooperate with tabs formed in the side panels to lock the receptacle into assembled condition and prevent up and down movement of the connector flaps relative to the rest of the receptacle structure.

Abstract: An apparatus and method for measuring the firmness of a paper roll product. The roll product is mounted on a spindle and a plunger is lowered into engagement with the outer peripheral surface of the roll product. A motion detector detects the distance the plunger moves into the roll product under the weight of the plunger and data based on this distance is displayed for viewing by the operator. Calibrating gauges are employed prior to measurement to ensure that a zero reading on the display corresponds to the point at which the plunger initially contacts the roll product outer surface.

Abstract: A perforated package of a composite integral sheet material which includes a first layer of absorbent material, a second layer of printable material and an impermeable pigmented polymer layer interposed between the first and second layers. The composite material has a plurality of air pockets formed between at least one of the first or second layers and the polymer layer, by discontinuously bonding the first or second layers to the polymer material. The package has two parallel lines of perforation which allow access to the interior of the package and to the foodstuff contained therein. A method of using the perforated package of composite integral material.

Abstract: Disclosed is a method for producing an absorbent creped cellulosic sheet having a high level of surface-perceived softness that comprises continuously forming a web of cellulosic papermaking fibers, adhering said web to a thermal drying means, treating said adhered web with an amido amine salt derived from a partially acid-neutralized amine, and creping said treated web from said thermal drying means.

Abstract: An apparatus and a method for forming coreless paper roll products are disclosed. Coreless paper roll products are formed by slitting a paper web to form web segments having side edges. The web segments are then wound about an elongated winder shaft. During winding of the paper web, liquid is applied to the web segments only at the side edges thereof while maintaining the web segments free of liquid between the side edges. When the rolls are formed and stripped from the winder shaft, the openings located at the ends of the roll at the roll central aperture will be well defined and allow ready insertion of a dispenser spindle. All the material of the roll can then be dispensed.
