Abstract: A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. Stanchions for supporting passengers while standing are shaped so that they curve upwardly and outwardly of the aisle to a wider spacing at the ceiling than at the seats. Between two stanchion mounting rails is provided a central ceiling panel dropped from the roof to define an air supply duct longitudinally along the aisle above the passengers. This is supplied with ventilation air by a roof mounted system and communicates by individual sub-ducts with a series of fans in the side walls.

Abstract: A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. The roof and floor are formed from a welded frame structure over which is applied a molded panel formed in single panel structure and bonded to the frame structure. The panel is formed by molding a sandwich using a thermosetting resin through top and bottom fiber reinforced sheets and a honeycomb layer of resin impregnated paper and foam between the sheets. The floor panel is shaped so that its thickness varies and its top and bottom surfaces deviate from an otherwise planar structure to incline downwardly at a door way and to incline upwardly to clear structural elements.

Abstract: A public transit vehicle has a passenger entrance ramp at a door way including a support frame for mounting on the vehicle at the doorway carrying a primary ramp panel, a secondary ramp panel and a fixed platform panel. The primary panel is pivotal through 180 degrees between a retracted position inverted within the vehicle and covering the secondary panel and the fixed platform panel and a deployed position in which the primary ramp panel is inclined from an inner edge downwardly and outwardly from the vehicle to an outer edge at the ground. The primary panel is pivoted at its inner edge on an outer edge of the secondary ramp panel pivotal which is in turn pivotal about an inner horizontal axis at its inner edge.

Abstract: A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. Each window comprises an outer pan attached into the window opening in the frame and a pane structure pivotally mounted in the pan. The pan is formed by four sides each of which is integrally defined by a web bridging the width of the frame, an exterior flange projecting outwardly and an interior flange projecting inwardly with the pan held in place by adhesive between the exterior surface of the frame and the exterior flange and between the web and the corresponding surface of the frame. The pan is thus imperforate to prevent moisture penetration.

Abstract: A portable air cooking apparatus for use in cooking ovens to create air currents which transfer heat to cooking food stuffs to promote more rapid and more uniform cooking or baking as described. The portable air circulating apparatus is intended to sit on the top cooking rack of a conventional oven and blow air down on food being cooked beneath it on the lower rack.
