Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.

Abstract: An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

Abstract: All embodiments of the present invention relate to a toothbrush to prevent tooth abrasion and gum damage during use. A first embodiment of the invention includes a handle including an open cavity and a neck interconnected to the handle by a pivot. The neck is movable between an aligned first position and a second angled position relative to the handle. A leaf spring is bonded to the end of the neck at a first end, and the second end of the leaf spring engages the handle to provide biasing resistance. The leaf spring is configured such that if pressure to the neck exceeds a threshold limit, there is movement of the neck portion from the first position to a second position. The threshold limit is the pressure just below the pressure at the brush that may cause damage to the hard and soft tissue of the mouth. A protective sheath envelops the junction between the handle member and the neck member to prevent accumulation of unwanted material within the cavity of the handle. A second embodiment is equivalent in structure and components to the first embodiment except that it also includes a manual adjustment of the biasing force of the leaf spring to provide variable pressure and a motor for providing mechanical movement of the brush head. Third and fourth embodiments are equivalent in structure and components of the first and second embodiments, respectively, except that the leaf spring is bonded to the handle instead of the neck.
