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.

The present invention relates to the use of agents that inhibit FcyRIIIb receptor activity, activation or expression for the treatment of inflammatory conditions such as Rheumatoid Arthritis. The invention also concerns screening methods that may be employed to identify said agents.
Abstract:
A method of making a cellulosic web includes: forming a nascent web from a papermaking furnish, the nascent web having a generally random distribution of papermaking fiber; b) transferring the web having a generally random distribution of papermaking fiber to a translating transfer surface moving at a first speed; drying the web to a consistency of from about 30 to about 60 percent including compactively dewatering the web prior to or concurrently with transfer to the transfer surface; fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric with a patterned creping surface, the fabric creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping fabric such that the web has a plurality of fiber-enriched regions arranged in a pattern corresponding to the patterned creping surface of the fabric, optionally drying the wet web while it is held in the creping fabric. Preferably, the formed web is characterized in that its void volume increases upon drawing.
Abstract:
A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.

Abstract:
The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.
Abstract:
A paper machine for manufacturing a structured soft paper web are described, which machine has a wet section, a press section, a drying section and a web-carrying clothing running around a suction device close to a smooth impermeable belt in the press section for the creation of a transfer point. In accordance with the invention, structuring means for structuring the web are arranged between the press section and the drying section. The structuring means comprise either said clothing in the shape of a permeable wire, the structure of which is made up of depressions and arched surface parts, including knuckles in a quantity of 25-150 knuckles per cm2, and a suction device that, at a vacuum of 40-80 kPa, draws the web to the structured side of the wire so that the web acquires the structure of the wire, wherein the wire operates at a speed less than or equal to the speed of the belt, or a creping doctor that is located in a space between the belt and the clothing and in scraping contact with the belt so as to loose the web during simultaneous crinkling, the suction device having a suction gap for initial suction of the web firmly to the clothing for transfer to a drying cylinder. The web-carrying clothing operates then at a speed that is less than the speed of the belt.
