Title: Systems and methods for bimodal device virtualization of actual and idealized hardware-based devices
Inventor: TRAUT ERIC
IPC: G06F13/10
Filed: 2004-10-19
Abstract: Various embodiments of the present invention are directed to bimodal virtual device approaches (that is, "bimodal devices"). In certain embodiments, the bimodal device is a virtual device that is primarily based on a real piece of hardware to provide a broad degree of compatibility with software running in the guest environment (similar to the hardware device virtualization approach). However, to overcome the problem of poor performance that plague hardware virtual devices, these embodiments also provide an idealized "high-performance mode" that is not found in the original hardware-based device. Software drivers (and other software) developed for interacting with the original hardware device and which are unaware of (and unable to use) the high-performance mode will continue to use the "legacy mode" (hardware virtualization), while enhanced versions of guest software will be able to recognize and utilize the high-performance mode (idealized virtualization).

Title: Adjustable sealing means
Inventor: PAUL NICOLAS
IPC: F16K31/524
Filed: 2004-10-28
Abstract: A valve has a valuing element which is rotatably fitted within a valve body.  This valuing element of the valve is joined by a stem or shaft portion which extends out of the valve body to interact with an actuator and transmit torque to the valuing element. In plug valves, pressure needs to be also applied to the valuing element to insure a proper closure. The invention relates to a mechanism to adjustably seal the stem/body interface using only one screw that is positioned on the front of the valve cover for easy access. The force generated by the screw is transposed into a vertical force and a horizontal force by a cam. The multiple faces of the cam are used to transmit the force vertically and horizontally and will maintain the mechanism in a straight position.
