Abstract: A dispenser is disclosed that facilitates loading of new rolls of material and the removal of empty cores. The dispenser includes a cradle roller spaced from a pair of abutment rollers. As a roll of material is dispensed, the diameter of the roll reduces causing the roll to drop from the cradle roller to a collection device. A transfer assembly pivots with the roll so that the sheet material continues to be dispensed from the dispenser without interruption. Once the roll of material drops to the collection device, a new roll of material can be loaded into the dispenser for automatic transfer to the new roll once the first roll of material has been completely depleted.

Abstract: The present invention provides systems, devices, and methods for using two or more flexible bands to constrain shoulder and/or hip replacement components to reduce dislocation and/or instability (e.g., constrain the glenosphere against a glenosphere recess, or constrain a femoral head against an acetabular component). In certain embodiments, one end of the flexible bands are attached to, or are held by, a first ring (e.g., expandable ring, such as a snap ring) that is configured to be operably connected (e.g., via a humeral baseplate) to a humeral stem, while another end of the flexible bands are attached to, or are held by, a second ring (e.g., flat ring, washer, annular, hoop, or orbital) that is configured to be operably connected (e.g., via a scapular baseplate) to a scapular bone. In some embodiments, an outer sleeve (e.g.

Abstract: A roll support assembly for a web material dispenser configured to contain a roll of web material having a first interior end. The roll support assembly includes a roll support mountable into the web material dispenser and including a roll-engaging portion with a peripheral wall engageable into the first interior end of the roll of web material with the roll of web material being rotatable relative to the roll support when engaged therewith and when a pulling force is exerted on the web material; and a rotation brake comprising at least one braking protrusion protruding outwardly from the peripheral wall of the roll-engaging portion and decelerating the rotation of the roll of web material by frictionally engaging at least one of directly and indirectly the roll of web material. The disclosure also concerns a web material roll dispenser with such a roll support assembly.

Abstract: A dispenser is disclosed that includes a housing defining an interior volume for receiving a stack of sheet products, an actuator, a dispensing member, a roller, and a support structure for engaging a front face of the stack including opposed shelves for supporting opposed sides of the front face. The actuator is operable by a user to activate a dispensing member to dispense a desired number of sheet products. The actuator includes two or more user interfaces that a user can actuate to transmit to the dispensing member an amount of movement corresponding to different numbers of sheet products being dispensed depending upon which of the user interfaces is actuated. The roller is located between the opposed shelves and engages and grips on the front face of the stack.

Abstract: An in-counter or in-wall dispenser including a product housing and a cover is disclosed. The cover is pivotally mounted so as to pivot between an open position providing access to the interior volume defined by the product housing for loading a new stack of sheet products and a closed position so that the sheet products are only accessible through a dispensing opening in the cover for one at a time dispensing of sheet products from the product housing. First and second tab-like members project from an interior surface of the product housing into the interior volume. With the cover open, the first and second tab-like members engage in a margin or border area of a front face of the sheet products positioned closest to the dispensing opening to hold at least the engaged part of the sheet products spaced from an interior surface of the anterior cover.

Abstract: A braking assembly used in a dispenser that dispenses a continuous supply of material such as paper. The braking assembly includes a support structure.
