摘要:
A roll supporting hub is adapted for acceptance of a plurality of rolls (one at a time), with each roll having a different predefined core width. The hub includes a hub body with a plurality of core support surfaces spaced circumferentially about a central rotation axis. One or more of those surfaces engage the core of the roll to secure the roll and hub together for coupled rotation. A stop surface on the hub body engages a first radial side of the core, while a radially retractable retainer surface engages a second radial side of the core. The retainer surface is secured to the hub body in one of a plurality of possible predefined axially disposed positions relative to the stop surface, each of which corresponds to one of the predetermined core widths of the roll being supported by the hub. The retainer surface is supported by a spring which is retractable within a slot extending axially between opposed support surfaces on the hub body.

Herein is disclosed an article support device capable of being attached to a mounting surface using a stretch-releasable adhesive tape, the device comprising a base and a support body that is rotatably and non-detachably connected to the base, wherein the support body is rotatable relative to the base, between a first position in which the base and the stretch-releasable adhesive tape are hidden, and at least one second position in which at least a portion of a pull tab of the stretch-releasable adhesive tape is visible.

Herein are disclosed methods and assemblies for adhesively mounting an article to two walls that meet at an angle (e.g., a corner). The methods and assemblies use first and second mounting plates that are deflectably and removably attachable to the article, with the first mounting plate being adhesively attachable to a first wall (e.g., by a piece of double-faced adhesive), and the second mounting plate being adhesively attachable to the second wall.

A package for dispensing sheet material from a stack includes a novel biasing device for urging the stack of sheet material toward an opening in one side of the package. The biasing device is comprised of a flat sheet of material sized and shaped to be located within the package beneath the stack of sheet material. An elastomeric element having an unstressed length that is less than a diameter of the flat sheet of material is stressed and positioned between opposite edges of the flat sheet of material. As stress is relieved from the elastomeric element, the elastomeric element draws the opposite edges together and elevates a central portion of the sheet of material in the form of an arch to urge the stack toward the opening as the stack of sheet material is depleted.
摘要:
To detect a turbid contaminant in a moving container, radiant energy having a wavelength that is absorbed by contents of the moving container that include the turbid contaminant at a different level than energy having the wavelength is absorbed by contents of the moving container that include a non-contaminant is directed into the container. Thereafter, a level of radiant energy scattered by contents of the container is detected. The presence of a turbid contaminant is indicated when the detected level of scattered radiant energy differs from a threshold level.
