Abstract: A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.

Abstract: A roof batten for use in spacing tiles or similar exterior roofing members from a roof overlayment is provided. In one embodiment, the batten includes at least one layer of a corrugated plastic material with a pair of generally planar plies and a convoluted ply cooperating with the planar plies to define a multiplicity of passages. The passages allow drainage of water infiltrating the tiles and further promote drying.

Abstract: A non-hierarchical or linear directory structure for a mass storage unit such as a disk. The directory structure can be kept in an auxiliary semiconductor memory. The disk is partitioned into segments of equal size. The directory structure presumes that data objects reside wholly and contiguously within a given area of the disk segments. While a variable number of objects may be stored within each segment, a given object is not allowed to occupy more than one segment. During a storage operation, objects are assigned to segments in a round-robin fashion, to equalize segment utilization.

Abstract: A reel wrap for wrapping a reel, the reel having a central spool separating a pair of end plates, and a reel width extending from an outer margin of a first of the pair of end plates to an outer margin of a second of the pair of end plates, said reel wrap includes a wrap central portion, said central portion means being substantially continuous and having a width between central portion edge margins at least coextensive with the width of the reel for spanning and enclosing an area between said pair of end plates. And includes first and second side portions for securing the central portion to the reel, the first and second side portions being securable to a respective side plate of the reel proximate a circumferential edge margin of the respective side plate of the reel. A method of wrapping a reel is further included.

Abstract: An air deflector for installation with a roof ventilator having a pair of vent parts defining a multiplicity of air passages, the air deflector comprising a base member and a generally upright air flow blocking member extending upwardly from the base member at a generally acute angle of 75.degree.. Two air deflectors extend along the entire length of the roof ventilator proximate to the outer edge of each opposing vent part. The base member is disposed between the bottom surface of the corresponding vent part, and the upright air flow blocking member confronts and is spaced apart a selected distance from the outer edge of the vent part and angles inwardly slightly toward the vent part. The top edge of the upright air flow blocking member angles slightly outward away from the vent part, and is disposed at approximately the same height as the top panel of the roof ventilator.

Abstract: A ventilating system for a roof made of a multi-plied weatherproof material. The weatherproof material includes a planar ply and a second ply joined such that a multiplicity of air passages is defined thereby. The air passages extend generally transversely to longitudinal axes of the embodiments. Each embodiment can be transported and stored in a spiral conformation. The spiral conformation is achieved by rolling the embodiment in a direction generally parallel to the longitudinal axis. A series of embodiments include a top panel and one or more lateral vents, rolled such that the one or more lateral vents are radially exposed. When shipped and stored in a spiral conformation, the embodiment with radially exposed lateral vents is more quickly and easily installed on a roof. Another embodiment, also conformable to a spiral for shipping and storing, is advantageously used to enhance ventilation by ventilating the eave.

Abstract: A ridge vent comprising a pair of opposing vent parts each fabricated from a plurality of stacked, interconnected layers of a corrugated plastic sheet material and a top panel extending between and connected to the opposing vent parts, with the entire assembled ridge vent being rolled into a spiral or coil, and secured in that configuration for later installation on a roof. The assembled ridge vent is rolled into the spiral configuration from an initially planar configuration by engaging a leading end of the ridge vent and rolling the ridge vent onto a drum or mandrel to form a tight, uniform spiral. The rolled vent can then be labeled and banded or packaged. The fabrication process from bulk rolls of sheet material to packaged roof vents can be substantially continuous and automated. Roof vents of various lengths or widths can be manufactured with only minor adjustments or substitutions in the fabrication equipment.

Abstract: A rolled ridge vent comprising a longitudinal blank of corrugated plastic sheet material having an undivided top panel extending its length, and segmented portions extending laterally from each side of the top panel scored to be folded into opposing pairs of vent parts. Adjacent segmented portions may be cut entirely through or perforated for manual separation. The entire blank is spiral rolled in the longitudinal direction. The ridge vent is installed by placing the roll on the peak of the roof with the free end extending over the top and oriented away from the direction of installation. The blank is unrolled to expose at least one pair of segmented portions, which are then folded under the top panel to form the vent parts and fastened to the roof. This process is repeated until the desired length is installed. Foam end caps and air deflectors optionally may be installed.

Abstract: A ridge peak roof ventilator comprising a pair of vent parts disposed on opposing sides of an opening in a roof peak, and a top panel disposed above and connecting each of the vent parts. The vent parts may be of unitary construction, folded from interconnected panels, or assembled from individual layers of sheet material, and each forms a multiplicity of air passages through which air flows from the interior to the exterior of the roof ventilator. The top panel is constructed from double-faced corrugated plastic having a pair of planar plies and a convoluted intermediate ply. The underside of the top panel is routed along the centerline to form a concave recessed area, thereby cutting away a section of one planar ply and part of the intermediate ply to form oval-shaped openings. Each opening has side walls traversing concave arcuate paths between a maximum height adjacent the side edges of the recessed area and a minimum height along the centerline.

Abstract: A ridge cap type roof ventilator comprising a plurality of sections aligned longitudinally with one another and hingedly interconnected along their confronting ends such that the plurality of sections may be folded or pivoted into parallel abutting contact. Once folded, several roof ventilators may be stacked with their vent parts in an overlapping, interfitted pattern to provide a stable column or stack having a minimal volume to conserve the space required to store or ship a predetermined number of the roof ventilators. The sections may be unfolded for positioning and installation on the ridge of the roof.

Abstract: A tote container for perishable produce such as asparagus comprising a pair of identical molded end shells which form the side walls of the tote container, with an intermediate blank cut and scored from a sheet material such as double-faced corrugated plastic extending between and securely attached to each of the end shells. The blank is folded to form a bottom panel, back panel, pivoting top lid and front lid panels, and a front tray panel to the tote container. The tote container defines a receptacle region with an open top and front, and the blank defines a bottom tray portion within that receptacle region.
