E04B 170

US Classification:

523021, 527201, 52 94, 52254

Abstract:

An improved moisture management system for installation over doors and windows in buildings that included exterior, stucco-covered, curtain walls comprising an integrally formed, three sided, elongated track including a base, an upright front wall that includes at its base weep holes for the removal of entrained moisture as well as a longitudinal forward extending finish stop above the weep holes, and an upright rear wall at opposing elongated edges of the base, and, extending angularly downward from the outside of the base, and integrally formed therewith, a drip plate that permits ready drainage of water exiting the moisture management system through the weep holes in the upright front wall. Preferably, elongated striations in the front faces of both the front and rear upright walls as well as holes in the upright front wall above the finish stop provide improved adherence of sealants and adhesives used in the installation process.

International Classification:

E02B 720

US Classification:

405 90, 405 42, 405 87

Abstract:

An end dam for a generally U-shaped moisture management channel comprising: a vertical wall having a front and a rear surface and a base edge; a first flange extending at a right angle from the rear surface in the area of the vertical wall base edge, integrally formed therewith, and having a distal edge and a base edge; and a second flange having a base edge extending from and integrally formed with the rear wall, spaced apart from the first flange and extending angularly away from the rear surface toward said first flange distal edge to define a slot between the first and second flanges. The first and second flanges of the end dam frictionally engage the base or bottom of a generally U-shaped moisture management channel causing the vertical wall to abut the sidewalls of such a device.

John A. Larson - Parkland FL

Assignee:

Plastic Components, Inc. - Miami FL

International Classification:

E04F 1304

US Classification:

52202, 52254, 52255, 523026, 52344, 52443

Abstract:

An improved curtain wall casing bead for installation on buildings having stucco or similar curtain wall exteriors. The improved curtain wall casing bead incorporates a mesh attached to at least the front wall of the casing or starter bead, which mesh extends beyond the height of the front wall and provides additional area for the infiltration of over-applied stucco finishes or the like. Such additional infiltration, after drying of the over-applied layer provides a more adherent, higher quality and more durable attachment of the stucco finish to the casing bead and the overall wall structure is achieved.

International Classification:

E04D 1300

US Classification:

52 95, 52 96, 523021, 527411

Abstract:

A soffit vent comprising a base having opposing elongated edges, a pair of parallel flanges extending upwardly from the base intermediate the elongated edges and defining: 1) a vent zone in the base characterized by the presence of vent holes in the base; and 2) attachment flanges formed by portions of the base extending beyond the location of the parallel upwardly extending flanges, the attachment flanges including holes therein for the insertion of attachment devices. A method for installing the soffit vent of the present invention in an EIFS or DEFS structure comprising locating the soffit vent in the appropriate location between a pair of insulating members in the EIFS or DEFS structure, attaching the soffit vent to the structure by the insertion of a suitable fastener through the apertures in the attachment flanges and into the foam insulation.

US Classification:

52 95, 52 94, 52 96, 52371

Abstract:

An improved ventilation strip for providing a soffit vent on a building. The ventilation strip includes an elongated perforated panel having a substantially planar upper surface and flanges extending laterally there from. A lip is provided on the lower surface of the panel at each edge of the panel running longitudinally thereon. The flanges are of non-uniform cross section and include an upper and a lower surface. The flanges are thickest at the juncture with the panel and thinnest at their outer ends with the lower surface tapering upward from the juncture to the end. Apertures may be provided in the flanges. The ventilation strip is operated by cutting a channel in the soffit of a structure, aligning the strip with the channel, and driving fasteners through the flanges to secure the strip to the soffit. Stucco reinforcement mesh may be secured across the flanges and the soffit and stucco spread thereon to complete the installation. In an alternative embodiment, the upper surface of the flanges may be provided with adhesive and a removable strip.

US Classification:

525061, 52202, 52408

Abstract:

An improved curtain wall casing bead for installation on buildings having stucco or similar curtain wall exteriors. The improved curtain wall casing bead incorporates a mesh attached to at least the base portion of the casing or starter bead, which mesh extends beyond the front edge of the base, and, when folded upward over the face of an inserted foam or curtain wall panel, provides additional area for the infiltration of over-applied stucco finishes or the like. Such additional infiltration, after drying of the over-applied layer provides a more adherent, higher quality and more durable attachment of the stucco finish to the casing bead and the overall wall structure is achieved.

Abstract:

Apparatus and method for emulating a virtual machine within the physical memory space of a programmable processor using virtual functions having a format independent of the hardware architecture of the processor. The virtual functions are executed using an execution engine emulated in the processor. A symbol table maps the virtual functions to native functions in the memory space, and a gate call interface block accesses the symbol table and initiates execution of the corresponding native function in response to each executed virtual function. Execution of the corresponding native function operates to evaluate the concurrent execution of at least one other native function. In this way for example, standardized platform virtual code can be generated for a number of different types of processors and used to evaluate the native operational routines of each processor.
