Flow enhancing restrictors are located within a fluid conduit to provide pressure reduction and flow enhancement. The restrictors may be used in combination with a conventional choke valve or as a stand-alone pressure reduction means. Alternative exemplary embodiments for flow enhancers are described. Each of the flow enhancers has a generally cylindrical base with at least one fluid passage disposed therethrough. Each of the flow enhancers also provides a dome that projects upwardly from the ce...

Methods and apparatus for use within a production pipeline or other flowbore to reduce fluid pressure and regulate fluid flow while minimizing erosion effects caused by particulate matter in the fluid, wherein varying geometries with respect to multiple components within a choke valve are utilized to effectuate multiple changes in fluid flow direction, causing a fluid pressure drop at each directional change.

A golf cup which effects an automatic ejection of a golf ball putted therein, wherein a tiltable, cup-like impacting means is operable to laterally restrain a golf ball and randomly locate the golf ball and thereafter undergo upward tilting movement operable to impart laterally and upwardly directed ball ejecting force to the golf ball.

An electric bicycle employing chain, V-belt or friction pulley drives and a motor controller circuit variable in both frequency and duty cycle. Regenerative braking and the conversion of the motor to a transformer for charging the bicycle battery is disclosed as is both tires and a rim adapter to convert a standard bicycle rim to a belt drive. The pressure of the armature brushes of the motor is variable under light load conditions to increase motor efficiency.

Method and apparatus for automating the ejector operation of a golf cup and featuring the use of flexing diaphragm and/or impacting cup to impart ball impacting force to a golf ball. A telescoping coil and magnet system operate to trigger a control circuit, in response to the presence of a golf ball, and this control circuit in turn causes the coil and magnet means to interact and impart ball impacting force to the ball. A pivoting impacting cup provides a multidirectional, pivotal movement, ope...

A barbeque grill including a lower housing, heating means and food support means positioned within the lower housing, an upper housing or hood adapted to enclose the lower housing, a smoke exhaust means provided in said upper and/or lower housing for allowing smoke to escape from within the barbeque grill, wherein said smoke exhaust means is retractable/collapsible in order to allow the oven or grill to take up the least amount of space when being stored or transported.

The present invention relates to foreign peptide sequences fused to recombinant plant viral structural proteins and a method of their production. Fusion proteins are economically synthesized in plants at high levels by biologically contained tobamoviruses. The fusion proteins of the invention have are useful as antigens for inducing the production of antibodies having desired binding properties, e.g., protective antibodies, or for use as vaccine antigens for the induction of protective immunity ...
