Abstract: ABSTRACT    A trailer having at least one gull wing door as well as conventional rear swing doors permits unhindered access to the interior of the trailer along the full length of the trailer at one time.  Each gull wing door is pivoted longi-tudinally at the approximate center of the roof and includes a roof portion which extends outwardly from the pivot axis and an integral sidewall portion which extends downwardly to the bed of the trailer.  Latch assemblies are incorporated to secure the doors to the trailer bed.  A pair of hydraulic cylinders are pivotally secured between the roof portion of each door and fixed trailer frame elements and are oriented substantially horizontally when the door is in its closed position.  Torsion bar spring assemblies disposed colinearly with the axis of pivot provide force which initially opens the door, offsetting the hydraulic cylinders from their substantially horizontal positions such that they are capable of providing sufficient force to raise the doors.          Typically, only the curb side of the trailer will include such gull wing doors but it should be readily apparent that both sides of the trailer may include such doors and that plural doors on one side may be utilized, if desired.

Abstract: ABSTRACT        A method and apparatus is disclosed for reducing acid rain caused by the combustion of fossil fuels in stationary combustion units, such as power plants, smelters or refineries.  Compounds such as nitric oxide and sulphur dioxide are discharged into the atmosphere from smoke stacks of these combustion units and this causes acid rain.          In this invention, these compounds are treated in the smoke stacks or flues of these combustion units by subjecting the flue gases to ozone and ultraviolet radiation produced by a plasma arc burner mounted in the flue.  This converts the offending compounds to water soluble oxides and an aqueous alkaline spray is introduced into the flue to dissolve and neutralize these oxides preventing the emission of the acid rain producing compounds from the combustion unit smoke stacks.

Abstract: TRUNK FOR PACKET SWITCHING     Abstract Fair and fast service to a plurality of channels served by packet switches at nodes interconnected through a common carrier facility is achieved by controlling the quantity of data sent from any one channel to another.          When data arrives at a node from a channel, the channel address is entered in line in the first of two channel address queues and the data is entered in a separate data queue.  Each channel address is read from the first queue, a predetermined number of data bytes is read from the corresponding data queue and sent in a frame to a distant node.  Thereafter, the channel address is entered at the end of the second, lower priority queue.  The frame may have data bytes from other first queue channels but the frame length is limited either by a predetermined number of bytes or when no more channel addresses remain in the first queue.  When no channel addresses remain in the first queue, a new frame is started by reading a channel address from the lower priority second queue. A frame may have data from a data queue corresponding to a channel address in the second queue followed by data from a data queue corresponding to a channel in the higher priority first queue.
