Abstract: Plastic cross ties constructed of a plastic pipe with two separate connectors attached to both ends act as a unit to position opposing masonry shells as part of a stay-in-place concrete form system. A three part cross tie assembly constructed of a pipe and concrete from connectors are snapped together with zip rods eliminating the need for screwing, nailing or gluing.

Abstract: A roof construction method using expanded metal lath laid on top of corrugated metal roof deck for the purpose of creating ventilation ducts in the valleys of the corrugated metal deck. The ventilation ducts created are vented to the building space below through vent slots in the valleys of the metal roof deck. A concrete slab with finished rubber roof poured in top of this roof deck with ventilation ducts will have enhanced ability to release moisture trapped from the concrete curing process.

Abstract: A stay-in-place concrete form includes masonry shells layered with rigid insulation tied with plastic cross tie assemblies. The masonry shells can be connected with plastic dovetail connectors that compensate for the variation in height of the shells. This allows for the shells, together with the connectors, to be a consistent height and allows for dry stacking. This dry stacking method can result in labor time and training savings over conventional masonry mortar construction.

Abstract: A configuration for split wedge dovetail dowels that provide attachment points along dovetail channels where wedge action locks the dovetail dowels in place through compression and friction without the need for glue or screws. This configuration can also be used to connect two members with matching dovetail channels by positioning the split wedge dovetail dowel across the joint between the two members.

Abstract: A stay-in-place concrete form includes masonry shells layered with rigid insulation tied with plastic cross tie assemblies. The masonry shells can be connected with plastic dovetail connectors that compensate for the variation in height of the shells. This allows for the shells, together with the connectors, to be a consistent height and allows for dry stacking. The masonry shells can be bonded together with a layer of lightweight concrete poured in a cavity behind the masonry shells and/or bonded together by mortar joints. This dry stacking method can result in labor time and training savings over conventional masonry mortar construction.

Abstract: A hair styling device which may include a handle and a heating element connected to the handle. The handle can include a proximal end, a distal end, and a longitudinal axis. The heating element may be connected to the distal end of the handle and include a surface. First and second combs may be arranged parallel to one another on opposite sides of the heating element and perpendicular to the longitudinal axis of the handle so that hair can be received through the combs and placed in proximity to the surface of the heating element.
