Abstract: A dynamic eave building system comprising a flexible joint for first vertical and second angulated structural members pivotally connected one to the other. The adjacent ends of the first and second structural members are mitered into a mating configuration and spaced one from the other by the pivot joint. The pivot joint comprises a pivot pin received through aligned apertures formed in one of the members and in a knee splice secured in the other. The knee splice is positioned to define the flexing space between the mitered ends. The second angulated member also includes moisture collection troughs formed longitudinally therealong. The first member is provided in a hollow configuration for receiving fluid flow from the troughs of the second angulated member. Both members are adapted for securement of conventional curtain wall material, siding or roofing thereon.

Abstract: A trench duct power compartment for use over a cellular raceway is fabricated by forming a rectangular-shaped blank and then stamping out a center section to leave portions which are contoured to the shape of the crests of the cellular raceway and thereafter bending the cut-out blank to simultaneously form upright side walls, downwardly extending concrete blockers together with connecting bottom end sections while leaving the bottom midsection open. The contoured portions of the concrete blockers having the same profile as the crests of the cellular raceway and snugly engage therewith.

Abstract: Insert has a plate member supporting one or more transition blocks for interconnecting power conductors from the power cell to the conductors of a flat cable together with an adjusting ring supporting a cover with a cable exit slot.

Abstract: A weigh axle transducer for a grain cart or other application in which side loads are applied. A spindle which mounts the cart on a wheel is provided with opposing side openings which form an I-shaped section of the spindle. Strain gauges are mounted on opposite sides of the web of the I section and are wired in a bridge circuit providing an output signal proportional to the shear strain on the web. Each opening has an undercut configuration which enhances the output signal due to the large diameter undercut area and which provides adequate strength against lateral loads due to the smaller diameter portion. Apertures through the web provide wiring passages and act as stress risers to enhance the signal.

Abstract: A curtain wall drainage system for horizontal mullions comprising a flexible, conforming flap member disposed in flush engagement against a weep hole formed in the mullion. The flap permits egress of water infiltrated therein while preventing infusion of water or air turbulence within the mullion from wind loading against the curtain wall. An upper portion of the flap member secured to the outer weep hole surface for permitting pivotal movement therefrom and the passage of water through the weep hole and beneath the flap member. The flap member is constructed of sufficiently resilient and conforming material to permit the presence of a stream of water beneath the flap member from the weep hole to the lower end portion thereof and the creation of a capillary action therein for urging water contained within the mullion downwardly beneath the flap member for discharge from the curtain wall structure.

Abstract: A fully adjustable, simplified system for installing a sloping roof on top of an existing flat roof is disclosed. Top and bottom roof spanning members are interconnected by individually vertically adjustable stanchions and the stanchions in the system are cross-braced in two orthogonal planes. The top and bottom spanning members of the system can be parallel or perpendicular to each other and the bottom spanning members can be eliminated and replaced by individual bearing plates where the existing roof structure allows direct loading at localized points. The system utilizes precut and prepunched components and utilizes offset hole punching to achieve a fine degree of adjustability which renders the system highly versatile.

Abstract: Certain calendar events, such as the standard/daylight time transition or a holiday such as Labor Day, always occur on the same alphabetic day always having the same relationship to the beginning or end of the same month in any year; however, their numeric day varies from year to year. In order to update the numeric day of such a calendar event that is used by a microprocessor of a programmable electronic real-time load controller, the microprocessor selects a reference day value representing the numeric day of the calendar event in a given year and selects a reference year value representing the numeric year of that year. At the beginning of each real-time year, the microprocessor determines a real-time year value representing the numeric year of the real-time year, determines a current numeric day value for the calendar event from the reference day value, the reference year value, and the real-time year value, and stores the current numeric day value for use during the current real-time year.

Abstract: The wall panel includes a snap joint which permits hidden attachment of the wall panel to another wall panel. The joint permits the panel to be attached to building supports from inside or outside and permits easy attachment of liner panels, insulation, or the like. A projection on one panel abuts an angled leg of another panel to provide a secure snap engagement between the panels.
