Abstract: The present invention provides a method and apparatus for transporting a motorized vehicle, such as a wheelchair, between the loading bridge and cargo bin of an aircraft in a timely manner. According to one embodiment of the invention, a metal cage assembly is implemented with a drop down ramp at the front and an adjustable floor that is raised by a lever handle on either side, outside of the frame. The assembly can be attached to an end of aircraft cargo belt loader by a strap that is wrapped around the belt frame and tightened via a ratcheting clamp. The adjustable floor can be raised or lowered at one end to offset the angle of the belt loader when it is raised to an upright position, for example, to reach a galley door of an aircraft. Angling of the adjustable floor can allow the floor to be substantially parallel to the loading bridge or aircraft cargo bin, thereby enabling the easy transfer of a motorized wheelchair to and from various compartments of the aircraft.

Abstract: A method and apparatus provides two testing stations at a single conveyor location to permits one part, such as electric motor armatures, to be tested while another part is being loaded or unloaded from a single conveyor system. Two testing heads are mounted on a reciprocating mechanism which allows the testing heads to be moved parallel to and independently of the conveyor system so that one or the other part may be aligned with a single loading and unloading station on the line at any given time. A part is first loaded into test station #1 and is then moved away from the loading station as testing station #2 is moved to it. When an electrical test on the part previously loaded into testing station #2 is finished, testing immediately begins on the part just loaded into test station #1. The part in testing station #2 is unloaded into the space vacated by the previous part, the conveyor is indexed, and the next part is loaded into testing station #2.

Abstract: A filter system for removing solid impurities from molten metal is described comprising a housing containing vertically disposed rigid coarse filter facing the incoming flow of molten metal and capable of removing solids having a particle size of at least 10 microns and a rigid fine filter mounted vertically behind the coarse filter and capable of removing solids having a particle size as small as 1 micron. The apparatus further includes a heater for maintaining the temperature of the molten metal and a sparger mounted adjacent the front face of one filter to provide an intermittent gas flow over the face of the filter to dislodge solids on the filter as filter cake. In a preferred embodiment, the rigid filters are nested cylinders, and the molten metal is directed to the center of the smaller coarse filter cylinder from which it then flows through the coarse filter outward to and through the fine filter cylinder and then from the fine filter out of the filter housing.

Abstract: Particulate lime is discharged from a nozzle into an electric arc furnace through an inlet port in the roof or top of the furnace. The inlet port is laterally displaced from the electrode ports in the center of the top of the furnace. Lime is supplied to the nozzle through a duct pivoted on the furnace to swing the nozzle into alignment with the inlet port for charging lime into the pot and into a retracted position where the nozzle is shielded by the top from heat produced in the furnace. The nozzle has an axial length, axial direction, and cross sectional shape and width constructed and arranged to direct the lime away from the side wall and toward the central portion of the furnace without any significant impingement of the lime directly on the electrodes.
