    Abstract: The present invention pertains to a computer pointing device having an annular rotating ring that is rotatable by a user to control the movement of a cursor on a computer screen. The annular rotating ring is preferably implemented around a trackball to facilitate the ease of use by the user. The annular rotating ring is made up of three constituent rings, namely, a finger ring, a bearing ring, and a shutter ring. The three constituent rings are constructed in such a way that they are interlocked to eliminate any unnecessary movement or slop during use.

    Abstract: An apparatus for sampling well production fluids comprises a vessel having an inner chamber. In addition, the apparatus comprises a hydrocarbon fluids outlet conduit in fluid communication with the inner chamber. Further, the apparatus comprises a well fluids inlet conduit coaxially disposed within the hydrocarbon fluids outlet conduit and in fluid communication with the inner chamber. The well fluids inlet conduit has a first portion extending from the vessel and a second portion extending into the inner chamber. The second portion of the well fluids inlet conduit includes a plurality of openings configured to direct the well production fluids radially outward from the well fluids inlet conduit. Still further, the apparatus comprises a sample fluids outlet in fluid communication with the inner chamber.
