Abstract: A double deck bus has a wide front entrance door and two rear exit doors, one from each deck. The upper deck is at selected standing headroom height from the lower deck, and at selected sitting headroom height from the vehicle roof. A channel passageway with selected standing headroom is provided lengthwise of the upper deck. A curved front stairway leads from the front entrance door to the front end of the upper deck passageway, and a descending stairway leads from the rear end of said passageway to one of the rear exit doors. The fare box is located within the curve of the front stairway to be visible to the driver, whose seat is well above the lower deck. An engine compartment is provided at the rear end of the bus, and a wall separates it from the lower deck passenger compartment.

Abstract: An apparatus to generate a wave-like pattern of forces on a surface effect ship utilizes a flexible membrane which undulates in a water wave-like manner, the crests of the waves transferring forces to the surface effect ship. The membrane is undulated in its sine wave configuration by means of a series of linkages, one link of which is pinned to the underside of the membrane. That link is reciprocally actuated and the combined movements of the various linkages cause the membrane to undulate as would water waves. The main drive motor drives a primary shaft to which are connected a series of gear boxes which in turn drive secondary drive shafts. By controlling or varying the speed of the primary drive motor, the frequency of the generated waves may be varied. At each linkage station there is a crank and the connecting rod is adjustably connected to the crank. The amplitude of the waves can be varied as desired by adjustably positioning the connecting rod along the crank.

Abstract: A vapor emission control system adapted to accommodate displaced vapors generated during the filling of a motor vehicle storage tank, wherein a first storage tank is adapted to communicate sequentially with an intermediate vacuum accumulator and ultimately with the intake manifold of an internal combustion engine.In the preferred embodiment a dispensing nozzle is inserted into vapor sealing engagement with a first liquid storage tank wherein said liquid storage tank is equipped with a unidirectional self venting gas cap. Upon insertion of the dispensing nozzle a unidirectional bypass line normally closed is opened via an entry port flap actuator.

Abstract: A liquid interface diffusion process for bonding titanium or titanium alloys wherein at least one of the titanium type materials to be fayed is sequentially plated with a total weight of from between 1 and 5 gms/ft.sup.2 of honeycomb core of layers of copper and nickel or an alloy made therefrom. The faying surfaces are then held together to maintain position on alignment, placed in a protective atmosphere, the temperature of the materials are then raised at a controlled rate causing sufficient solid state diffusion to occur and a liquid to form continuing to increase the temperature to a predetermined level and holding at this temperature until a solidification occurs and sufficient additional solid state diffusion occurs producing a desirable dilution of bridge material and titanium at the joint, and then reducing the temperature at a controlled rate to a lower temperature to complete the bonding cycle.

Abstract: In a bus or other vehicle propelled by an internal combustion engine, a plurality of engine accessories are mounted on bosses provided on both sides of an upright, triangular, transversely mounted accessory drive casing which is resiliently mounted on the vehicle frame at one side of the engine.Three parallel accessory drive shafts are journaled, one within each apex of the casing, one of which, the power input shaft, is driven from the engine. The other two shafts are driven from the power input shaft. Both ends of each shaft project from the casing and the accessories are mounted on the casing in driven relation with such shaft end portions.

Abstract: A unitary sandwich panel having a polyurethane core and aluminum facing sheets, forms bottom and back support portions of a seat cantilevered at one end thereof from a transit vehicle wall or other vertical support. Cushions, arm rests, and a molded back cover are attached to the panel.

Abstract: In a transit vehicle, such as a bus or rail car, wherein each vehicle side wall comprises a framework of upright posts or mullions spaced apart for mounting the vehicle windows therebetween, and covered exteriorly below the windows with strakes of extruded aluminum, slots are provided at selected heights in the front and rear sides, respectively, of each two mullions between which a seat is to be mounted. One mounting tab extends from the wall end of the seat portion of each seat, and another from the wall end near the upper end of the seat back portion. These mounting tabs are inserted one in each of the openings provided in the facing sides of two mullions between which the seat is to be mounted, and the seat is secured in such position by a retaining screw which anchors the seat to the wall.

Abstract: A wall-mounted, side facing seat for a transit vehicle comprises a cantilever mounted support frame consisting of a pair of end members with marginal flanges, and a stretcher interconnecting the lower portions of the free ends of the frame end members. A seat insert formed of sheet material with integral end portions and conforming marginal flanges fits between the frame end members and is supported by the frame. Angle channel members receive and retain conforming flange portions of the frame and insert, while an insert back portion slopes downwardly and rearwardly from the upper edge of an insert back portion to the vehicle wall to provide clearance from, and access to, a vehicle window in back of the seat.

Abstract: An improved railway truck for providing non-contact active support between the unsprung and the sprung elements as well as lateral stability and banking of vehicles used in surface supported transportation systems having unsprung surface contacting elements, sprung load carrying elements, magnetic force fields, inertial and position sensing elements mounted on the sprung element and a non-linear feedback circuit for actively varying the strength of the force field to maintain a relatively stable air gap between the unsprung and sprung elements while also holding the sprung element to a smooth course notwithstanding irregular surface conditions encountered by the surface contacting elements or variations in loading on the load carrying element.

Abstract: The leading edge of the jet engine nacelle is provided with structure to prevent the formation of ice particles at the inlet of the jet engine. The nacelle is split into leading and trailing chambers and there is a partition separating the chambers, the leading one of which includes the anti-icing apparatus. The leading chamber includes a double skin generally facing interiorly toward the jet engine and that double skin defines the nacelle therebetween which permits the passage of the hot gases which heat the outer skin from the inside thereof. Conduit means controllably pass hot exhaust gases from the jet engine to within the leading chamber from where they pass into a cell via a series of spaced apertures formed in the inner double skin. A series of spaced channels are formed between the inner and outer skins and connect the leading and trailing chambers.

Abstract: In a small airplane, a combination nose wheel, shroud and rudder is provided. The shroud encloses all but a lower cord of the wheel. The shroud has an aerodynamic profile and is pivotable for inflight guidance by a pair of actuator pedals pivoted to the interior structure of the cabin. The shroud is directionally operatable by the pedals operating through a bellcrank and connecting rod. The shroud is returnable to a normal straight flight condition by airstream forces alone. An additional interconnection is provided from the shroud for simultaneously controlling a conventional rear rudder.

Abstract: A hand assist rail for a transit vehicle comprises an aluminum extrusion of Y cross sectional shape with a bulbous, preferably laterally offset, bottom portion shaped for gripping by hand of a passenger standing in the aisle of such vehicle. A resilient cushion of conforming shape comprises the under side of the bulbous hand grip bottom portion, and a web portion of the rail which comprises the stem of the Y preferably is reversely curved to permit the thumb and fingers of a hand grasping the bulbous bottom portion to overlap.
