Abstract: Al2O3—La2O3—Y2O3—MgO ceramics (including glasses, crystalline ceramics, and glass-ceramics) and methods of making the same. Ceramics according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. The particles and fibers are useful, for example, as thermal insulation, filler, or reinforcing material in composites (e.g., ceramic, metal, or polymeric matrix composites). The thin coatings can be useful, for example, as protective coatings in applications involving wear, as well as for thermal management. Some embodiments of ceramic particles according to the present invention can be are particularly useful as abrasive particles.

Abstract: Methods of making ceramics, including ceramic abrasive particles, comprising alumina (in some embodiments, alpha alumina). The ceramic abrasive particles can be incorporated into a variety of abrasive articles, including bonded abrasives, coated abrasives, nonwoven abrasives, and abrasive brushes.

Abstract: Methods for making glasses and glass-ceramics comprising Al2O3 and SiO2. Glasses made according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. Some embodiments of glass-ceramic particles made according to the present invention can be are particularly useful as abrasive particles.

Abstract: Glasses and glass-ceramics comprising at least 75 percent by weight Al2O3, based on the total weight of the glass or glass-ceramic, respectively, and at least one metal oxide other than Al2O3. Glasses and glass-ceramics according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. Embodiments of glass-ceramic particles according to the present invention can be are particularly useful as abrasive particles.

Abstract: A portable easel includes an easel body with a slot formed therein for receiving the lower end of a member having a painting surface. A connector has a notch formed therein for receiving the top end of the member. An elastic element extends between the connector and the easel body to bias the member toward a tilted orientation.

Abstract: A vehicle trailer hitch mounted table and chairs which can be used for tailgate parties. The seats on the chairs swivel, and the table includes a dismountable umbrella. The table, chairs and umbrella can be dismounted from the vehicle, or can be changed to a traveling position in which the umbrella and table top are removed, and the seats are attached to the frame of the device, which is still mounted to the trailer hitch of the vehicle.

Abstract: A box for carrying and protecting a painting includes a primary panel and side and end panels connected to the primary panel and disposed orthogonally with respect to the primary panel. The panels are locked together to define a box interior for holding a painting. Pairs of engagement members located at the corners of the box project into the box interior and maintain the painting spaced from the primary panel and out of engagement with the primary panel. The box is formed from a unitary blank.

Abstract: A shoe soling composition of vulcanizable type composed of a blend of high cis polybutadiene, elastomeric copolymer of styrene/butadiene containing 22.5 to 24.5 mol percent of styrene and a thermoplastic block copolymer of styrene/butadiene, plasticized with hydrocarbon process oil and a synthetic resin and reinforced with a powdered silica.
