Abstract: A modular assembly that is configured to be magnetically coupled to another object, such as a white board or glass board, is provided. The magnetic strength of the modular assembly can be adjusted. The modular assembly includes an article, such as a tray or other type of holder for receiving materials like markers and papers, and a module that houses magnets. The article can include a magnet housing portion with a magnet housing retention feature. The module can include a magnet housing with one or more magnets held therein. The magnet housing can include an article coupling feature. The module can slide into the magnet housing portion of the article and be secured in place by the engagement of the magnet housing retention feature and the article coupling feature.

Abstract: An eraser assembly is provided that includes a housing, a tray, a coupler, and an eraser insert. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion of the housing and a mounting portion disposed opposite the retaining portion. The coupler is configured to releasably hold the tray to the housing. The eraser insert is configured to be mounted to the mounting portion. An eraser insert is also provided that includes a first side and a second side, an eraser pad, and a coupler. The first side includes a mounting surface and an eraser pad is disposed on the second side. The coupler is disposed on or about the mounting surface and is configured to detachably connect the eraser insert to an eraser assembly at the mounting surface.

Abstract: An eraser assembly is provided that includes a housing, a tray, and a coupler disposed between a surface of the tray and a surface of the housing. The housing has a concave shape including an interior portion. The tray has a retaining portion disposed in the interior portion and a mounting portion disposed opposite of the retaining portion. The coupler is configured to releasably hold the tray to the housing. An eraser insert configured to be disposed in the interior portion of the housing and to be enclosed by the tray.

Abstract: A clip is provided that is configured to secure an object therein. The clip includes a front portion having a first end, a second end opposite the first end, an inner surface, and an outer surface. The outer surface of the front portion is configured to face away from the object. The base portion has a first end, a second end opposite the first end, an inner surface, and an outer surface. The inner surface of the base portion is configured to face the inner surface of the front portion. The outer surface of the base portion is configured to face away from the outer surface of the front portion. The clip includes a connector coupling the front portion to the base portion such that the front portion is movable in two degrees of freedom relative to the base portion. At least one magnet is coupled to at least one of the front portion and the base portion. The at least one magnet urges the inner surface of the front portion and the inner surface of the base portion together.

Abstract: An apparatus for connecting a writing implement to a glassboard, whiteboard or the like has a housing adapted to be connected to a writing implement. The housing has a side surface with an opening formed therein and a recess extending from the opening into the housing. A magnet is disposed in the recess and has a first pole at the opening. The magnet provides a magnetic field in a direction away from the side surface of the housing. The apparatus enables a side periphery of a writing implement coupled with the apparatus to magnetically couple with the glassboard, whiteboard or the like in a predetermined orientation regardless of the initial orientation of approach of the writing implement even in the presence of a similarly magnetically self-supporting writing implement or object.

Abstract: A magnetic rotor arrangement is provided, having a primary rotor including an array of magnets arranged to provide alternating polarity around the outside of the primary rotor and at least one auxiliary rotor including an array of magnets arranged to provide alternating polarity around the outside of the auxiliary rotor. The primary rotor and each auxiliary rotor are arranged such that when the primary rotor is rotated, the rotation of the primary rotor magnetically induces rotation of each auxiliary rotor.

Abstract: An apparatus to secure a ladder to a ferromagnetic support such as an exposed ferromagnetic support comprises a pair of bracket clamping assemblies removably attached to a rung on a ladder. The brackets are pivotally bolted to magnet mounts, which each hold a permanent magnet that releasably holds the ladder in place against the support. The apparatus prevents the ladder from slipping, and further serves to hold the ladder at the proper angle for safe use. The apparatus finds particular application where exposed ferromagnetic metal beams are available in the workspace but tying a ladder for safety would be impractical.

Abstract: An apparatus to secure a ladder to a ferromagnetic work surface, such as a metal storage tank, comprises a pair of brackets removably attached near the top of the ladder. The brackets are hinged to magnet mounts, which each hold a permanent magnet that releasably holds the ladder in place against the work surface. The apparatus prevents the ladder from slipping while a worker is climbing the ladder or while working from the ladder.

Abstract: A multi-sheet article comprising a plurality of sheets is disclosed. Each of the sheets has opposite first and second faces that share a common perimeter edge. Each sheet also has an edge margin that extends from a portion of the perimeter edge of the respective sheet. The edge margins of the sheets are bound to each other in a manner connecting the sheets to each other. At least a first one of the sheets comprises a first removable portion and at least one frangible connection that is configured and adapted to facilitate the separation of the first removable portion from the remainder of the first sheet and from the other sheets. This first removable portion comprises a portion of magnetized material. However, the edge margin of the first sheet of the multi-sheet article is devoid of magnetized material.
