A load transfer apparatus accommodates movement between adjacent concrete slabs. The load transfer apparatus includes a spine in a form of an elongated hinge having a longitudinal axis A. A first dowel and a second dowel project radially from the spine and are located at two spaced points along said longitudinal axis A.
Lightweight Inflatable Borehole Receiver Unit For Seismic Testing, Michael Kalinski
Lightweight Inflatable Borehole Receiver Unit For Seismic Testing, Michael Kalinski
Civil Engineering Faculty Patents
A borehole receiver for seismic testing has a support frame and an inflatable membrane configured to form a single, compact unit. The inflatable membrane has at least one sensor, such as an accelerometer affixed to the membrane. The at least one accelerometer may be adhesively affixed to an interior portion of the membrane with a cyanoacrylate adhesive. A pneumatic inflation system is used to inflate the membrane with pressurized air. In use, the membrane is slipped over the support frame and secured with a pair of O-rings. Once the borehole receiver is properly positioned in the borehole, pressurized air from …
Self-Flushing Fluid Seal Assembly, David T. Kao
Self-Flushing Fluid Seal Assembly, David T. Kao
Civil Engineering Faculty Patents
A self-flushing fluid seal assembly is provided to prevent particle intrusion into the main seal around a slurry pump shaft. The assembly includes an annular tube concentrically disposed about the pump shaft and forming a chamber. The volume of the chamber is made variable by a plunger comprising an enlarged diameter portion of the pump shaft movable relative to the chamber during the power and return stroke of the pump. Flushing liquid is delivered to the chamber by means of a feed line extending through the shaft. A check valve provided in the feed line opens to allow the inward …
Self-Flushing Piston Assembly For Slurry Pump, David T. Kao
Self-Flushing Piston Assembly For Slurry Pump, David T. Kao
Civil Engineering Faculty Patents
A slurry pump is provided having a self-flushing piston assembly mounted in a mating cylinder. The piston assembly includes a first piston having a peripheral sealing member and a reciprocating piston rod for driving the first piston for pumping action. A second piston mounted adjacent to the first piston includes a sealing member and forms an enclosed chamber with the first piston. A lost motion coupler connects the pistons together and varies the size of the chamber. On the return stroke of the piston assembly, flushing liquid on the non-slurry side is sucked into the chamber as the chamber expands. …
Hydropower Turbine System, David T. Kao
Hydropower Turbine System, David T. Kao
Civil Engineering Faculty Patents
There is disclosed a new cavitation free hydraulic turbine system which fully utilizes well-established hydrodynamic theories useful for low-head hydroelectric applications. The hydropower turbine system of the present invention makes use of a fixed blade propeller turbine with reverse blade angle and an upward flow passage. To eliminate the complex flow control adjustable vane system and elaborate tube design and construction of the prior art, the new turbine system is provided with a vertical needle valve and a near zero absolute velocity free exit flow design.
Rotary Feeder For Solid Particle Injection Into Pressured Fluid System, David T. Kao, Don J. Wood
Rotary Feeder For Solid Particle Injection Into Pressured Fluid System, David T. Kao, Don J. Wood
Civil Engineering Faculty Patents
A rotary feeder for injecting solid particles into a pressurized fluid system is described. The system includes a hopper for receiving particles and a device for transporting the particles from the hopper to a feeder roller. The cylindrical feeder roller includes a plurality of recessed troughs that are positioned at an angle from the axis of the cylindrical roller. Particles are transported from the hopper to the recessed troughs of the feeder roller and are subsequently fed into a venturi section of a solid-liquid slurry pipe system. The rotary feeder for injecting solid particles into a pressurized fluid system is …
Resonant Footing Test Apparatus, Bobby O. Hardin, Woodrow W. Thurman
Resonant Footing Test Apparatus, Bobby O. Hardin, Woodrow W. Thurman
Civil Engineering Faculty Patents
An apparatus for conducting resonant footing tests upon undisturbed soils includes an oscillatable mechanical structure with attachable electrical means for causing both oscillation of the structure and measurement of the behavior of the soil under test. The apparatus is transportable to the site at which the test is conducted on soil in-situ, and is adapted to be employed under selective loadings applied downwardly upon the oscillatable structure.
