Abstract: A seal device for sealing slide-out room opening in recreational vehicles. The seal including a base; a bulb; an alignment aid member; and a positional member. The base having a proximal end, a distal end, an inside portion, an outside portion, and a perpendicular member. The bulb having an arcuate portion, a sidewall portion and a curled end portion. The positional member extending perpendicularly to the base distal end in opposite direction of the alignment aid member. The seal device may further include a flap extending co-linearly from the base distal end and a fastening system.

Abstract: The shingle installation jack devices may be mounted once at a first roof level, providing support for the walk board. When installation or repair of the shingles is complete at the first level of the roof, the shingle installation jack devices may be operated in tandem to raise the level of the walk board to a second level of the roof. Shingle installation and/or repair may then be carried out at this second roof level without the need to re-mount the walk board supports at the second level. The shingle installation jack devices may also be run in reverse to lower the walk boards. The shingle installation device includes a frame and utilizes a winch motor to adjust the effective length of a cable and thus adjustably raise or lower the walk boards to any desired roof level.

Abstract: The invention provides methods of making provisional and long-term dental restorations, particularly dental veneers, crowns and bridges. In one embodiment, the restoration can be fabricated indirectly by a dental laboratory. In another version, a dental practitioner can make the restoration chairside for a patient in a dental office. A polymerizable dental composite material, which is dimensionally shape-stable in its uncured state, is used to make the restoration. A substructure such as a metal coping can be used to support the polymerizable material. The material includes a polymerizable acrylic compound, polymerization initiator system capable of being activated by light or heat, and preferably a filler material. The resulting dental restoration has good aesthetics, mechanical strength, and margins and contacts.

Abstract: Dental guards, particularly night guards, used by patients to protect their teeth against the effects of grinding and bruxism are provided. Methods and kits for making such dental guards are also included. A light-curable polymerizable arch material is used to fabricate the dental guard. Preferably, the material contains polymerizable acrylic compounds, color-changing cure indicator, and particulate filler. The material is molded to conform to the shape of a dental arch of a patient and light-cured to form the dental guard.

Abstract: The present invention is directed toward an adhesive for and a method for bonding artificial plastic teeth to a denture base. The adhesive employs a number of adhesion promoter monomers, dimers or oligomers and a cure package, as well as methyl acetate as a solvent. The method according to the invention includes exposing a plastic tooth to the adhesive and allowing the plastic to soften (not dissolve). The adhesion promoter chains infiltrate the plastic tooth matrix, such that upon curing a secure bond is formed.

Abstract: A pneumatically operated hoist system including a load support is disclosed, wherein the system is capable of sensing an overload and preventing the raising of the load support.

Abstract: A hoarding module 100 is disclosed which cooperates with other modules for erecting a hoarding and includes a substantially rectangular panel member 101 and positioning means in the form of a sleeve set 69, 70 and sleeve 71 which positions the module to adjoin at least one other module along at least one vertical side thereof. Positioning means 69, 70 and 71 cooperate with joining means in the form of pins 80 to hinge together horizontally adjoining modules in a hoarding.
