Abstract: An automated beverage monitoring system including one or more electronic scale assembly having a scale, a radio frequency identification tag reader, one or more batteries, one or more processors, one or more transceivers for transmitting and receiving wireless data, one or more data storage devices and a user interface. The automated beverage monitoring system also including a radio frequency identification tag that is affixed to a beverage dispenser. The radio frequency identification tag is configured to be read by the radio frequency identification tag reader of the electronic scale assembly when the beverage dispenser is placed on the electronic scale assembly. The automated beverage monitoring system also includes a remote device, such as a computer or mobile smart phone, in wireless communication with the one or more electronic scale assembly.

Abstract: A rod guide 10 for positioning on a sucker rod includes a sleeve-shaped guide body 12 and two or more spiraling vanes 14, 16 each extending radially outward from the sleeve-shaped body, with each vane spiraling about the body and defining a flow path between circumferentially spaced vanes. Each vane has a forward portion 24 spiraling in a forward direction, and a backward portion 26 spiraling in a backward direction rotatably opposite the forward direction. The rod guide may be used for either reciprocating rod or rotating rod applications.

Abstract: A field-installable rod guide for a rod moveable within an oilfield tubular having an interior tubular surface for driving a downhole pump to pump liquids to the surface through the oilfield tubular. The rod guide comprises a body including interfitting body members. An outer tapered surface on one body member is engaged by an inner taper-engagement surface on the other body member, to urge the body members toward a rod gripping position about the rod. The mechanism disclosed provides a particularly strong engagement with the rod, so that the rod guide may be used for either reciprocating or rotating rods. For rotating type rod guides, an outer sleeve may be included about the body.

Abstract: A rod guide for a cylindrical rod. The rod guide includes a cylindrical body surrounding and coaxial with the rod. A first pair of opposed fins extends from the cylindrical body, each first fin having a pair of planar sidewalls parallel to each other and parallel to the diameter of the cylindrical body. A second pair of opposed fins, each has a pair of radiused sidewalls wherein each second fin extends outward radially from the cylindrical body to a terminal end with the fin widest at its terminal end.
