Abstract: The present disclosure relates to a self-regulating, landfill well control system for automatically controlling a flow of landfill gas (LFG) through a wellhead associated with a landfill well at a landfill. The system has a combination unit operably associated with the wellhead, with a valve actuator, a flow measurement element and a controller. The valve actuator controls a LFG flow control valve, to thus control an LFG flow through the wellhead. The flow measurement element produces differential pressures proportional to a LFG flow rate. The controller controls the valve actuator and, based on data obtained using the flow measurement element, adjusts a setting of the LFG flow control valve to obtain a specific control point setting, and automatically maintains the control point setting thereafter.

Abstract: The present disclosure relates to a system for controlling an extraction of landfill gas flow (LFG) from a plurality of wellheads at a landfill. The system has a first wellhead located at the landfill, a first processor having a first rule set, and a first LFG flow control valve controllable by the first processor. A second wellhead is located at the landfill in a vicinity of the first wellhead and has a second processor and a second LFG flow control valve. The second processor has a second rule set and is operable to control the second LFG flow control valve. The first and second processors use their said rule sets to control the first and second LFG flow control valves, respectively, to control an LFG flow through their said first and second wellheads, respectively.

Abstract: A landfill well control system is disclosed which provides the ability to input a user selected set point to control a flow related variable at a landfill wellhead. A flow control actuator controls movement of a landfill gas (LFG) flow control valve. A sensor may be used for sensing the flow related variable. A controller is operably associated with the flow control actuator and the sensor. A user interface has a set selection for enabling a set point associated with the flow related variable, which is to be controlled by the system, to be input by the user. The controller operates to control the LFG flow control valve as needed to maintain the set point in an autopilot-like fashion.

Abstract: The present invention provides a method for computer-controlled creation of non-occluding earpieces with tube bore. The non-occluding earpieces are created based on a three-dimensional computer model of at least part of the outer ear and at least part of the auditory canal. The said model is created by a laser scanner, in the ear scanner or by other means. The said three-dimensional computer model is virtually modified to create the non-occluding earpieces and the tube bore. Finally the physical non-occluding earpieces are manufactured using rapid prototyping equipment.

Abstract: A method for producing an objective substance such as sphingoid bases and sphingolipids using yeast is provided. An objective substance is produced by cultivating yeast having an ability to produce the objective substance in a culture medium containing an additive that is able to associate with, bind to, solubilize, and/or capture the objective substance, and collecting the objective substance from cells of the yeast and/or the culture medium.

Abstract: A method for producing an objective substance such as phytosphingosine and sphinganine using yeast is provided. An objective substance is produced by cultivating yeast having an ability to produce the objective substance and modified so that the expression and/or activities of proteins encoded by LCB4 and CKA2 genes are reduced in a culture medium, and collecting the objective substance from cells of the yeast and/or the culture medium.

Abstract: An air stripper apparatus is disclosed which incorporates a plurality of trays that are removably supported within a cabinet. A plurality of downcomers are also fixedly disposed within the cabinet, rather than on the trays. Removing the downcomer from each tray enables a simpler, lighter and easier to clean tray to be constructed.

Abstract: A well cap assembly is disclosed which is well suited for use with a wellhead. The well cap assembly has a port component and a cap element. The port component has a bore extending therethrough, an upper neck portion, and an upper threaded portion. The port component further has a lower threaded portion and a barb formed on the upper neck portion. The barb can receive an external flexible tube which is temporarily secured to the port component. The cap element has an internally threaded portion which engages with the upper threaded portion of the upper neck portion and seals the bore of the port component. The cap element also has a tether for securing it to the port component.
