Abstract: A threshold system for a door incorporating a seal and a threshold plate. The seal mounts to the door and has a flap extending therebeneath. The threshold plate has a raised inner section connected to a recessed outer section by an upstanding lip. The threshold plate disposed below the door so that the flap of the seal contacts with the upstanding lip of the threshold plate, thereby creating a seal between an outside area and an inside area. An outer deflector is mounted on the door body to deflect air and moisture away from the threshold plate and seal.

Abstract: A mid-roof anchoring system includes a series of anchoring channels secured to the roof structure along a line midway between the eave and the ridge of the roof. Metal roof panels installed over tile substructure are permitted to float laterally on the roof, except where they are attached to the anchoring channels. As a result, the roof panels expand or contract in both directions away from the midway line. This approach minimizes thermally induced movement the upper and lower edges of the roof, and minimizes reaction forces at the anchor.

Abstract: An angulated door assembly affording reduced entry and exit time and motion therethrough. Each door is angulated relative to the adjacent walls and/or the conventional path of ingress/egress therethrough. Such an assembly configuration affords increased sealing capacity as well as convenience for the user. The door opens and closes faster by swinging less than a conventional door, which presents itself orthogonally to the path of ingress/egress. By utilizing a pair of angulated doorways, the doors self-seal against each other while providing the advantages of angulated disposition relative to the path of ingress/egress.

Abstract: A latch arrangement for an access opening cover on a bulk material storage structure. The access opening will include a frame defining an opening periphery, with the covers hinged for movement between a closed position and an open position. Each cover will include at least one slide bar extending between sides of the cover. Each slide bar has a length such that the ends of the slide bar are in proximity to the frame. Lock studs extend inwardly from the frame, with one stud associated with each end of each slide bar. Each slide bar is mounted for sliding movement perpendicular to its longitudinal axis in the plane of the cover between latched and unlatched positions, and includes a stud face and a lock face. The stud face includes slits through which the studs may pass at the closed position of the cover, allowing the bar to drop down over the stud. When dropped down over the stud into the latched position, the lock face abuts against the stud, arresting movement of the bar.

Abstract: Two-part floor box disassembled at job site so one part can be connected to conduit without interference from the other part and then the parts reassembled for the pour. Parts are preferably a stamped sheet metal base and a plastic housing which can be slipped into and out of a cavity in base. Radially extending wiring compartments provide for feed thru and for feeding power from outside to the inside of the box structured so any combination of power and communication can be employed.

Abstract: This patent discloses a floor box for a service distribution system in a concrete floor slab. The floor box has a bottom, end walls, and side walls that define an interior of the box and a frame support that is positioned within the box and engages end walls and side walls to maintain the end walls and side walls in close conformance at their junction. The frame support also supports an activation frame of an activation kit positioned within an upper opening of the floor box. The floor box is less expensive to manufacture than floor boxes that are manufactured to maintain structural integrity independent of a surrounding concrete floor slab.

Abstract: A roofing system includes a strong nonmetallic mesh fabric placed loosely over an array of purlins, and secured fast at the periphery of the roof. The fabric, which serves to support roof insulation between the purlins, also has sufficient strength to protect workers laying the insulation, or roofing panels over the insulation, as well as those on the ground below, in case of an accident.

Abstract: This patent discloses a floor fitting for activation of services including electric power and communication services. The floor fitting includes activation sides sized to at least overlie two conventional duplex power receptacles. The floor fitting further provides for routing of service conductors through the fitting to locations above the floor. Additionally, the floor fitting provides for mounting of connectors to the base of the floor fitting and independent of the cover and for accepting decorative cover treatments at ends of the floor fitting adjacent to the activation sides.

Abstract: A floor box having structure which eliminates screws for holding the cover assembly on the box, the structure permitting the box and the cover assembly to be shipped in a disconnected condition and arranged, after the box is set up for the concrete pour, to be quickly and easily snapped into and maintained in closure position.

Abstract: Simplified access device for flush floor fittings in the form of a track mounted slider. The slider can be manipulated between a closed position wherein the interior of the fitting is shut off to any desired minimum opening position to accommodate exiting of one or more cables. The slider is never divorced from the fitting and so is available in the event the station is abandoned.

Abstract: An improved rectilinear building structure using diagonal tension members to resist racking to improve the tolerance of transitory transverse loads such as those that are produced by seismic occurrences. The improvement comprises placing a resilient pad in compression between at least one end of a tension member and a structural member whereby the resilient pad is compressed when the tension member is under tension so that the resilient pad deforms under the transitory transverse load thereby increasing the ductility of the structure before fracture of the tension member occurs.
