摘要:
The present invention relates to a device which may be mounted to the front of a tractor and which is operative to fold over corn stalks and the like before they engage the front tires of the tractor. The device positions dragging units in front of each of the front tires of the tractor, whereby the dragging units are dragged over the ground in front of the tires when the tractor is moving. The weight of each of the dragging units is sufficient to cause it to substantially fold over corn stalks and the like prior to their engagement with the front tires of the tractor, thereby greatly minimizing wear to the tires caused by engagement with the corn stalks and the like.

A handheld tool for removing soft material from an object includes a scoop portion supported by longitudinal handle portion. The scoop portion has a concave wall extending upwardly from a bottom to terminate in a rim edge. The rim edge may have a first edge portion on a first lateral side so as to form forming a first cutting edge with a first cutting characteristic, a second edge portion on a second lateral side so as to form forming a second cutting edge with a second cutting characteristic, and a third edge portion extending transversely of the longitudinal axis to form a third cutting edge. The scoop portion may be rotatably supported on the handle portion. The handle portion may have a proximal portion supporting the scoop and a flattened distal portion offset from the proximal portion. A transverse ridge may be located proximately to the scoop portion.

摘要:
A method for determining the flow rate of a fluid, having a liquid fraction and a gas fraction, comprising the steps of: measuring the pressure and temperature of said fluid at a flow control device through which said cyrogenic fluid passes; inputting said measured pressure and Cv into an algorithm; and performing a single or multi-step iteration to determine a fluid mass flow rate of the fluid through said flow control device using said algorithm that relates the mass flow rate of said fluid to said Cv, and mass densities of said liquid fraction and said gas fraction of said fluid which are a function of said measured pressure, and temperature. A system is also provided.

摘要:
Systems and methods are provided that relate to determining the phase compositions of a multiphase fluid flow in a fluid line, including determining a flow velocity parameter which is related to the flow velocity of the fluid flow in the fluid line using a flow sensor and obtaining a vibration signal from the fluid flow using a vibration sensor comprising a target disposed in the fluid flow which vibrates in response to fluid flow in the fluid line. The signal may be analyzed to determine an energy parameter which is related to the energy of the vibration signal within a frequency band, and a phase composition parameter, such as a dryness parameter, relating to the phase compositions of the fluid flow is determined using the flow velocity parameter and the energy parameter. An apparatus for determining the phase compositions of a multiphase fluid flow in a fluid line is disclosed.
