Abstract: A bridge deck (10) is supported by tensile supports (11 and 12) and stabilized to reduce the overall aerodynamic lift on the deck (10) by the addition of aerofoil stabilizers (19 and 20) pivotally secured about respective axes (21) generally longitudinal of the deck (10). The stabilizers (19 and 20) are driven by a mechanism (21 to 26) operable by angular movement between the deck (10) and the tensile supports (11 and 12) to articulate the stabilizers (19 and 20) to a position which will generate a force, in the presence of a cross wind, to reduce the overall aerodynamic lift on the deck (10).

Abstract: An apparatus for raising a component of an underground sprinkler including a hydraulic actuator in fluid communication with a pressurized fluid source normally associated with an underground sprinkler system, and operably connected to a base of the underground sprinkler. The hydraulic pressure provided by the pressurized fluid source is used to drive the hydraulic actuator and adjust the level of the base of the underground sprinkler within the ground. In a particular embodiment, the hydraulic actuator includes a hydraulic cylinder and a wand in fluid communication with the pressurized water source. The wand is inserted into the ground around the sprinkler base, thus fluidizing the ground and allowing the operator to more easily move the sprinkler base.

Abstract: An improvement for use with a pier installation apparatus of the type employed in lifting and supporting a foundation is provided. The invention comprises a mounting beam assembly for mounting hydraulic power cylinders in a straddling position around a pier to be driven into the ground by the installation apparatus. The beam assembly is a planar member having a central opening for receiving the pier therethrough. It is comprised of opposing plate members upon which the hydraulic cylinders are mounted. The plate members each have an opening which allows passage through of the piston rod of the hydraulic cylinder. The mounting beam assembly allows for lateral placement around a pier in the installation apparatus, and may be completely disassembled for quick and efficient installation and removal.

Abstract: This invention provides for painting a second coat upon a set of parallel striped lines in exact registration in one pass of a motorized painting vehicle for such applications as painting aircraft taxi stripes at airports. Beads are also registered on one of the lines in the same pass. Provisions are made for maintaining registration about curved lines by steering around curves with a shortened wheelbase vehicle and by extending paint nozzles for striping a plurality of parallel lines, typically a center twelve inch wide yellow line between two six inch wide black lines, outboard from one side of the painting vehicle. The vehicle comprises two four wheeled units articulated together by a universal articulation joint permitting vertical articulation so that the leading and trailing wheels may be lifted off the ground to reduce the wheelbase for steering around curves.

Abstract: Apparatus is provided for self-righting a signpost after it has been tipped over comprising a plate for connecting to the signpost and a complementary tray secured to the ground. Most of the apparatus is located below ground out of harm's way. The tray has upturned peripheral edges within which the plate resides. A chain is connected to the plate, extends through a hole in the tray and into the bore of a pipe for connecting to the bottom of a compression spring. When the signpost and plate tip, the plate rotates within the tray, displacing the chain and compressing the spring. Preferably a lip extending over the edge of the plate causes the plate to ride up the edge of the tray, increasing the chain's displacement. The increased tension in the chain urges the plate and signpost to right themselves. The plate and tray are complementary and square shape so that the square sides engage during tipping and prevent rotation of the signpost's orientation when it returns to the upright position.

Abstract: The paving system has a perforated pavement covering a deep substrate of mainly hard nodules or shells, the whole being surrounded by impervious walls to provide temporary storage in the interstices for chemical spillage or flood water, wherein liquids may be chemically treated or biologically decomposed, and from whence the rate of outflow may be regulated, the pavement consisting of preformed pavings of brick, concrete or other material, laid edge to edge without mortar or cement, and these pavings can be perforated or notched to allow liquids to run down into the substrate. The pavings are laid on a screen which filters out solid particles to reduce clogging. The system allows biological substances to grow, or be introduced, with or without additional nutrients, and allows chemical treatments to be introduced, from above, when needed. The whole pavement system can be lifted out for cleaning or, substitution, and relaid as new.

Abstract: A traffic management system is provided including a primary dispensing post and a banner having an inboard coupled to the primary dispensing post to be dispensed and retracted by way of a crank. The banner has traffic managing indicia positioned thereon. Further, a terminal post is connected to an outboard edge of the banner for maintaining the same upright.

Abstract: A pipeline connection assembly includes a landing platform and rotary or swivel connection hub which may be attached to a pipeline branch, termination, or manifold. The landing platform is mounted so that it may be rotated about the connection hub. This permits the installation of a subsea connection on a near level platform and allows the pipeline to be laid subsea with greater roll angles than would be acceptable otherwise. Orientation of the landing porch horizontally removes the requirement to manufacture the connection jumper to compensate for the roll differences in the hubs. In the preferred construction, the elevation of the platform can be adjusted by a remotely operated vehicle (ROV) and locked into place once the adjustment is completed.

Abstract: A lifting assembly for raising and supporting an edge of a foundation includes a lifting saddle slidably received over a pier that is driven into the ground adjacent the edge of the foundation, a bracket supported by the lifting saddle and adapted to be affixed to and to support the foundation, and a load transfer device configured to be supported atop an upper end of the pier. The lifting saddle is connected to the load transfer device by threaded rods slidably received through the load transfer device. The bracket is pivotally connected to the lifting saddle such that the bracket can rock side-to-side, thus self-aligning and remaining aligned with the foundation during a lifting operation. The bracket can also pivot about a vertical axis and can slide in a forward or rearward direction relative to the lifting saddle. The lifting saddle can pivot relative to the pier about a horizontal axis.
