Various embodiments of tiles or devices that are used to create a structure used to cover a floor other surface are described. Preferred tiles or devices comprise one or more magnetized surfaces that may comprise one or more magnets or ferrous material. The magnetized surfaces can be used to magnetically couple adjacent tiles or devices to form the flooring or other structure. In some embodiments, the tiles or device may comprise one or more routed edges.

A tile system for covering a surface. The tile system comprises a first tile assembly connected to a second tile assembly by a connector. Each tile assembly comprises a first tile stacked on a second tile, the first tile and the second tile joined to a reinforcing material disposed therebetween. The connector comprises a first component and a second component that is complementary to the first component. The first component is mounted to the first tile assembly, and the second component is mounted to the second tile assembly.

A removably mountable temporary work surface is disclosed herein. In some embodiments, the removably mountable temporary work surface includes a toolless mounting bracket, a spacing bar, and a hinge affixed to a work surface. The toolless mounting bracket may be configured to mount to construction framing. The spacing bar can be configured to extend or retract for use and storage. In various configurations, the work surface may include a metallic material and include one or more mechanisms to secure contents to the work surface, such as magnetic tethers. The work surface can be sized to form a substantially contiguous surface when mounted to adjacent framing posts.

A method for producing a surface covering system comprising magnetically receptive layers affixed to surface covering units and magnetized underlayments for use in securing surface covering units to supporting surfaces. The system includes isotropic magnetized floor covering units and anisotropic magnetized underlays for securing surface covering units. The system includes a set of formulations including ferrites and rare earth materials, oils and plasticizer and binding agents to optimize performance to meet design and application criteria.

Improved stripper solutions for removing photoresists from substrates are provided that typically have freezing points below about 0° C. and high loading capacities. The stripper solutions comprise dimethyl sulfoxide, quaternary ammonium hydroxide, and an alkanolamine having at least two carbon atoms, at least one amino substituent and at least one hydroxyl substituent, the amino and hydroxyl substituents attached to two different carbon atoms. Some formulations can additionally contain a secondary solvent. The formulations do not contain tetramethylammonium hydroxide. Methods for use of the stripping solutions are additionally provided.

Various embodiments of interconnectable pieces are described that collectively form a surface. The pieces comprise one or more routed edges or cutouts that can be configured to receive an insert used to couple adjacent tiles to one another. Some inserts may comprise one or more magnets or magnetized portions to magnetically couple the pieces with adjacent pieces.
