Abstract: A safety gate to be mounted on a loading dock. The safety gate includes a pair of vertical columns which are mounted on the floor of the dock on either side of a doorway that can be enclosed by an overhead door. A barrier or beam is mounted for sliding movement on the vertical columns and can be moved from an upper storage position where it is located above the doorway to a lower operative position where it extends across the doorway and will prevent material handling equipment, or other objects from accidentally passing through the doorway and falling to the driveway adjacent the dock. The barrier is composed of a pair of elongated side members which are connected by a pair of end members and a series of spaced transverse members. Each column is disposed in the space between an end member and the adjacent transverse member, and the outer surface of one of the side members facing the dock is provided with a resilient shock absorbing layer.

Abstract: The invention concerns the use of actively tuned liquid dampers to quench vibrations in large civil structures. Such vibrations may be induced by earthquakes or high winds. The effective length of the liquid damper tank determines the natural frequency of the liquid, and thus the effectiveness of the damper at particular excitation frequencies. The liquid damper is tuned by rotating baffles to regulate the effective length of the damper tank.

Abstract: A seismic brake assembly comprises an annular pipe journaled through a gripping block which frictionally engages the pipe about the pipe's outer diameter. The force with which the gripping block frictionally engages the pipe is controlled by a Belleville or spring-loaded washer. By securing the gripping block to one point in a structure and by securing one end of the pipe to another point in or associated with the same building or structure to be supported, the seismic brake functions as a rigid member of applied lateral stresses less than a design threshold. When the applied lateral force exceeds the design threshold, controlled sliding friction between the rod and gripping block is experienced, whereupon the building or structural framing returns the seismic brake to its nominal position when the seismic activity ceases. By controlling various factors including the diameter of the pipe and the tension with which the block engages the pipe, virtually any desired hysteresis loop may be achieved.

Abstract: A molding trim for a vehicle includes a hinged flange that is molded in an open position, such that mold lifters are not required to remove the molding from the mold. The hinged flange is connected to a hollow molding body by a living hinge that is integrally formed with the molding body and hinged flange, to permit the hinged flange to be pivoted to a closed position, wherein the hinged flange is positioned against a fixed flange on the molding body. More specifically, the hinged flange is formed with an engagement lip that is advanced against the fixed flange, and continued advancement of the lip causes the lip to ride against and past the fixed flange, such that the fixed flange holds the hinged flange in the closed position. Respective strips of double-backed adhesive tape are affixed to the flanges to hold the molding onto a vehicle body when the hinged flange is in the closed position.

Abstract: A fastening device for anchoring a sealing strip on a roof includes an elongated fastener which penetrates both a holder and the sealing strip and has a drill tip at a lower end thereof extending into the roof substructure. An opposite upper end of the fastener has an enlarged upper end engaged in an opening in the holder to press the holder against and anchor the sealing strip on the roof. A cover having a recessed underside for receiving the holder and a central hole with a slit-like depression for receiving a catch-shaped projection extending upwardly from the head of the fastener is rotated to drive the fastener and the holder into position on the sealing strip while at the same time covering the opening in the holder to prevent entry of rainwater and the like. As the cover engages the sealing strip, the cover eventually disengages the fastener so that only the cover rotates.

Abstract: A composite, prestressed structural member and methods of forming such a member. The apparatus includes a plurality of longitudinally extending girders and a deck unit attached thereto. The deck unit may comprise a plurality of adjacent composite units disposed on the girders, with each composite unit having a plurality of beams with a molded deck portion formed thereabove. In one method, the structure is formed by positioning the girders on a construction support adjacent to a center portion of the girders such that the free ends of the girders cantilever and deflect downwardly. The beams of the composite units are attached to the girders in this construction position. In a second method, the structure is formed by positioning the girders in their normal operating position such that they are supported on opposite ends, and then providing a support for a center portion of the girders such that at least a portion of the lower edges of the girders are placed in compression.

Abstract: The service life of wooden poles such as utility poles is increased by forming the butt end portion thereof with slots that penetrate deeply into the wood, these slots being formed prior to pressure treatment of the wood with preservatives and thus improving the penetration of the preservatives into the wood. After drying, the butt end of the pole is encased in a shell, suitably of polymers, that is bonded to the butt of the pole and presents a barrier to the penetration of fungus or insects, and likewise prevents the passage of liquids which might leach preservative from the pole into the surrounding ground.

Abstract: A jig having top and bottom collar with the top collar being either smaller than the bottom collar or the same size. The collars are joined by four stakes welded to the bottom collar which are used to level the jig. A third collar, called a centering collar, is attached to the top collar and has a pipe attached to it which extends down into the center of the jig to suspend a second pipe in the exact center of the jig. The centering collar and pipe have a lifting eye attached thereto, so a crane can lift the jig and completed stone post and move it to a new location. The stakes of the jig can be used as a guide to plumb and level stone which can be laid to form a stone post.
