Abstract: A process for mixing concrete onsite in quantities of 1-yard or more, which makes use of the embodiment of a large industrial bag similar to those used for waste management of rubbish and an overhead rail system adapted to a dump trailer, which suspends the bag from straps attached to the bag and pined to the rail system. The four-sided system of columns and rails adapted to the trailer allows two of the four rails to be moved using winches, allowing mixing of the aggregate, cement and water without the use of metallic blades and rotating containers. The winch draws one rail attached to one side of the bag and releases and the opposing winch draws and releases the opposing rail attached to the opposing side of the bag. The bag allows the material to be placed away from the locked gates and opened for unloading concrete.

Abstract: An electromechanically operated fuel nozzle having continuously adjustable flow rate settings between a closed position and maximum flow. The fuel nozzle includes a fuel dispensing pipe for dispensing fuel; an electromechanical valve device to control a flow of fuel in the fuel dispensing pipe, comprising an inlet pipe and an outlet pipe. The electromechanical valve device comprises at least one continuously variable flow electromechanical valve to control the flow of fuel; an electronic board for operating the at least one continuously variable flow electromechanical valve; and electric accumulator means for electrically powering the at least one variable flow electromechanical valve and the electronic board such that the predetermined portions provide the particular one of the flow rate settings. The electromechanical valve preferably comprises a servomotor controlled ball valve.

Abstract: A system and method for positioning oilfield tubulars on a drilling floor (2), having an automated tubular handling system, to permit alignment and automated make up and break out of threading operations between a stationary tubular (8) and a moving tubular (34), utilizing image information from radially offset cameras (54, 56), processing the image information to recognize the tubulars within the image and develop position information for said tubulars, combining the position information from the two camera systems to develop three dimensional information for each of the tubulars, developing instructions for the automated tubular handling system to bring the stationary and moving tubulars into vertical alignment and lowering the moving tubular into threaded contact, and engaging an automated hydraulic torque wrench to make up the threaded connection.

Abstract: An electromechanically operated fuel nozzle having at least four flow rate settings including maximum flow, minimum flow, and a plurality of intermediate flows. The fuel nozzle includes a plurality of solenoid valves, each configured to, upon actuation, permit a predetermined portion of the maximum flow through a fuel-dispensing pipe. The fuel nozzle also includes an electronic board configured to, in response to input indicating selection of a particular one of the flow rate settings, selectively actuate one or more of the solenoid valves such that the predetermined portions provide the particular one of the flow rate settings.

Abstract: A system for recording writing performed on a surface includes a rechargeable stylus, a rechargeable eraser, and a charging station for one or both of the rechargeable stylus and the rechargeable eraser. Each of the rechargeable stylus and the rechargeable eraser includes a pair of charging rings. The charging rings are disposed so as to contact a corresponding pair of charging contacts on a receptacle on the charging station for the stylus or the eraser. The receptacle, charging contacts, and charging rings cooperate to charge rechargeable stylus or the rechargeable eraser when the stylus or eraser is placed into the receptacle.

Abstract: A removable circuit interrupter with circuit-testing capabilities. In one embodiment, a removable circuit interrupter is provided for use with a battery-powered device. The battery-powered device includes a battery and a load that is electrically coupled to the battery. The removable circuit interrupter is configured to be disposed between the battery and the load. The removable circuit interrupter includes a first outer surface having a conductive layer. The removable circuit interrupter further includes a second outer surface having an non-conductive layer. The conductive layer is configured to electrically couple to one of the battery and the load. The non-conductive layer is configured to electrically couple to another one of the battery and the load.
