An apparatus for controlling airborne pollution comprises a leeward wall located near a polluted region, and a windward wall located between the leeward wall and the polluted region. The leeward wall and the windward wall are spaced apart so as to define an airflow passageway therebetween. The windward wall extends upwardly to a first wall height. The leeward wall includes an upper portion extending above the first wall height. The upper portion is adapted to direct airflow downward through the airflow passageway towards at least one opening located below the first wall height for exhausting the airflow from the airflow passageway.

A scoring and weighting system and method for providing print device selection on the basis of product characteristics that are specified for a print product is provided. The system determines the properties of one or more printing devices in relation to the product characteristics. The printing devices have one or more print mediums for providing the print product. A score is derived by determining a status respecting the conformity of the one or more print mediums to the product characteristics and evaluating the one or more printing devices' properties. Associating that score with each of the one or more printing device. Also, associating the print product with a print job and utilizing the score to route the print job to one of the one or more printing devices to produce the print product on one of the one or more print mediums.

An aerial refueling system utilizes the full drogue-probe coupling event as a control parameter for hose control. A variety of different types of signal sending and signal receiving devices may be used to indicate a coupling event between the drogue and probe. A positive coupling signal may serve to trigger a hose reel actuator to take up slack in the hose 16.

The present invention provides a converter filter that includes a bandstop frequency range to protect against overloading of the input circuits of legacy converter boxes from the relatively high power upstream return path signal between 5 and 85 MHz. The converter filter also functions to pass the downstream signal path with minimal loss and reflection. The converter filter comprises a circuit including a low pass filter and high pass filter in parallel with each other that operate to substantially pass signals in a first frequency band of approximately 5 to 52 MHz and a second frequency band of approximately 85 MHz to 2 GHz while substantially blocking signals in a third frequency band of approximately 52 MHz to 85 MHz.

A method of filling a plurality of bottom gusseted pouches disposed on a roll in a top-to-bottom end orientation is provided. The method comprises unwinding the respective bottom gusseted pouch from the roll; providing access to an interior compartment defined by front and back panels and the bottom gusseted end of the respective bottom gusseted pouch; filling the interior compartment with at least one item to produce a filled pouch; and cutting the respective bottom gusseted pouch from the roll by cutting between the top end of the respective bottom gusseted pouch and the bottom gusseted end of an adjacent bottom gussetted pouch connected to the respective bottom gusseted pouch.
摘要:
An air drying system for OBOGS is provided. The system comprises a bypass valve having an opened state and a closed state. The bypass valve is in fluid communication with an air inlet providing pressurized air. A dryer unit is configured to produce dried air when the bypass valve is in the closed state. An OBOGS unit produces oxygen enriched air while a purge valve has an opened state and a closed state. When the bypass valve is its closed state, the purge valve is in its opened state thereby directing a portion of the dried air to the oxygen generating system unit and a portion of the dried air to the dryer unit. When the bypass valve is its open state the pressurized air passes directly to the OBOGS unit.
