Abstract: A railway car for transportation of motor vehicles. The railway car may be articulated, comprising two or more units. The railway car may have end doors which are pivotally attached to the roof of the railway car. Flexible seals may be provided along the inner and outer edges of the end doors. Ventilation in the side walls of the railway car may be provided by small diameter perforations grouped at elevations near the top and bottom of each level. The side walls may be constructed by a combination of load bearing side wall panels which function as shear plates, and vertical posts. Protection for the door edges of motor vehicles being carried in the railway car may be provided by providing a plurality of parallel horizontal strips of a relatively soft material along the inside of each side wall on each level. A flexible enclosure may be provided between adjacent car units. A heat-reflecting corrosion-resistant coating may be provided on the galvanized steel corrugated roof to extend the life of the roof.

Abstract: An acoustic imaging device for providing an image of a body in a medium, includes a plurality of acoustic transmit elements and a plurality of acoustic receive elements, an apparatus for activating one of the transmit elements to generate an ultrasonic signal, an apparatus to selectively receive and record from each of the receive elements a set of data representing a phase, amplitude and transit time of the ultrasonic signal, a first computing apparatus for calculating a velocity map of propagation velocity values in each of a plurality of volume elements including the body and the medium using the data set, and a second computing apparatus for calculating a reflectance map, including a coherent sum of reflectance values at selected points in the plurality of volume elements using the data set.

Abstract: A shredding and feeding system for an incinerator, wherein a shredding chamber is isolated from atmosphere by means of an airlock through which material to be incinerated passes into the shredding chamber. The oxygen content of the shredding chamber is maintained below a predetermined level to minimize risk of explosions and premature incineration of material.

Abstract: A method and apparatus for associating received pulses with one of a plurality of emitters emitting pulses at periodic intervals. Periodic pulse trains are detected by computing the difference in arrival times between each received pulse and a fixed number of previously received pulses. In the simplest embodiment, a periodic pulse train is detected when one of the computed differences is one-half of another computed difference. In other embodiments, further processing is performed to detect staggered pulse trains or other periodic patterns.

Abstract: A chock block for a vehicle transported on a deck to secure the vehicle against longitudinal movement; the chock block having a first member and a longitudinal second member lateral to the first member; the first member nesting with a track on the deck and removable from such nesting by upward displacement; the second member extending along and terminating beyond the tread face of a vehicle tire; a pin on the chock block for removably securing the first member to the track to prevent the chock block from horizontal and upward movement; the second member having a longitudinal center when viewed from the top; the chock block being essentially symmetrical about the second member longitudinal center; and the pin having a handle observable and manually operable from both sides of the second member longitudinal center to withdraw the pin forward end from a track hole to remove the chock block from the track and to help position the pin forward end in a track hole.

Abstract: A railroad car for transporting vehicles comprising a first deck having side sills and being supported near each end by a railroad truck; a vertical side wall along each side of the car; each side wall including a plurality of spaced apart vertical columns having lower ends rigidly connected to each of the side sills; a second deck horizontally located above the first deck and rigidly connected to the columns; the second deck having a hinged section joined to each opposing end of a central portion, rigidly connected to the columns, to pivot about a horizontal axis; each hinged section being vertically pivotal and having an outer end with a lock attached to it to movably secure the outer end in upward and downward positions; each hinged section having side edges; a laterally movable, spring-biased rod along each hinged section side edge; the rod having a forward end extendable beyond the hinged section side edge into locking engagement with a retainer on the adjoining car wall; the rod forward end having outwa

Abstract: A railroad car for transporting vehicles such as automobiles and trucks has a pair of door assemblies which close each end of the railroad car. The lower end of the door assemblies are guided in a track and the track has vertically retractable sections located where the vehicle tires roll so as to provide added load height when the car ends are open and vehicles are being loaded or unloaded. An embodiment with a pivotal, counterweighted Z-shaped member upon which the retractable track section is mounted is disclosed along with an embodiment utilizing a vertically displaceable tubular member and a coil spring.

Abstract: An enclosure for the end opening of a vehicle having one or more interior elevated decks includes a pair of door assemblies each comprising a plurality of pivotally joined panels. The door assemblies are suspended in a vertical manner by means of hanger assemblies having tracking elements guided within a rail member disposed above the level of a vehicle elevated deck. Transverse movement of any panel concurrently displaces the entire associated door assembly, as a unitary articulated assembly, between a closed position sealing off the end opening, and an open position with the door assembly well-spaced from a lateral edge of the deck, in which latter position maximum lateral clearance is provided for lading carried by all decks or levels.

Abstract: A railway car having an end opening includes a swingable folding door assembly provided with a keeper mechanism carried by the door assembly and the adjacent side wall of the railway car. As the panels of the door assembly are folded from a flat, closed position overlying the car end opening to a collapsed, open position disposed substantially longitudinally extended away from the end of the car side wall, a guide rod carried by the door assembly is arcuately displaced to simultaneously horizontally shift a vertical locking pin to a position overlying an aperture in a lock plate whereupon gravity concurrently drops the connected rod and pin to secure the open door assembly in a fixed position.

Abstract: An enclosure for a vehicle end opening disposed between two side walls includes a pair of bi-fold door assemblies, each comprising inner and outer panels hingedly connected to one another with the outer edges of the innermost panel in turn hingedly connected to a hinge rod normally disposed adjacent the outer limits of the end opening. Intermediate lock means are included with each pair of door panels for selectively precluding relative displacement therebetween and when actuated allows of folding of each pair of door panels to provide a collapsed juxtaposed relationship following which the folded door assembly may be pivoted about the hinge rod 90.degree. or until parallel to the vehicle side walls.

Abstract: A lock mechanism for a railway car hinge-deck section includes a locking lever pivotally attached to a railway car and having an upper and lower wedge bar alternately engageable with a wedge plate carried by the hinge-deck section when the section is displaced to a raised or lowered position, respectively. Seat means affixed to the car restrict vertical displacement of the deck section and cooperates with mating inclined surfaces on the wedge bars and wedge plate to provide positive, tight retention of the hinge-deck section in either of its locked positions.
