Abstract: An improved synthesis loop for the production of ammonia has a low pressure, i.e. less than 100 atmospheres, a water absorption recovery system which utilizes low level heat recovered from the process for producing the synthesis gas to distill the ammonia-water mixture and an ammonia absorption refrigeration system which utilizes the same distillation column for both the water absorption system and the refrigeration system.

Abstract: A flatrack container for container loads has a pair of bulkhead assemblies at either end of a load platform, with each of the bulkhead assemblies including a telescoping assembly carrying stacking and lifting fittings being vertically adjustable so that the fittings can be positioned at any desired vertical position. One of the bulkhead assemblies is pivotally mounted so that it may be swung to the ground to serve as a drive-on ramp to aid in loading the container.

Abstract: A catalyst regenerator is disclosed which incorporates a closed vessel having a centered stand pipe concentrically arranged within a spent catalyst distributor. The catalyst is carried upwardly by the distributor and is scattered evenly and concentrically about the distributor. The spent catalyst is deposited on or near the top of the dense phase catalyst bed. A symmetrically arranged, preferably triangular fresh air distributor system including a number of transverse branches having small nozzles mounted thereon forms a grid pattern below the lower portions of the catalyst bed in the regenerator. Air for burning of the coke on the spent catalyst is introduced evenly to minimize the size of the air bubbles in the dense bed. The catalyst in the lower portions of the bed has a minimum of coke remaining thereon. The oxygen of the air which is introduced in the lower portions of the bed is consumed by combustion of the reduced quantity of coke in the lower portions of the bed.

Abstract: A railway car comprises a plurality of vertically disposed decks above the floor of the car. The first deck includes a rigid deck section having at opposite ends thereof hinged deck sections which may be moveable from a load carrying position upwardly to a raised position to facilitate loading of the car floor. The hinged deck sections are provided with counterbalancing means and a lock is provided for locking the sections either in the raised or lowered positions whereupon vehicles may be driven onto the deck sections.

Abstract: An improved synthesis loop for the production of ammonia, has a low pressure, i.e., less than 100 atmospheres, a water absorption recovery system which utilizes low level heat recovered from the process for producing the synthesis gas to distill the ammonia-water mixture and an ammonia absorption refrigeration system which utilizes the same distillation column for both the water absorption system and the refrigeration system.

Abstract: A semi-dump level indicator comprising an electrical system including a pair of mercury switches mounted on the rear portion of the trailer. The switches are closed when the trailer is level. When the trailer is dangerously tilted gravity causes one of the switches to open which de-energizes a relay closing a warning light and alarm buzzer circuit in parallel with the circuit having the mercury switches to warn the operator not to raise the trailer.

Abstract: A conveyor structure of the roller type includes an alignment device for maintaining relatively flat objects in aligned positions with respect to each other. The device includes a plurality of second rollers disposed between the rollers of the conveyor, the second rollers being eccentrically rotatable about axes extending longitudinally or perpendicular to the axis of the first rollers. The second rollers move upwardly between the first rollers to engage the flat underneath surface of articles traveling on the conveyer to lift them up and to move them laterally into engagement with a positive stop position to one side of the conveyer, whereby the objects are then relatively aligned with respect to each other.

Abstract: An acceleration indicator including an anti-tampering arrangement adapted to be secured to a railway freight car for detecting pre-selected destructive impacts on the the car. The indicator includes a generally hat-shaped casing having a normally obscured movable plate or flag carried therewithin by a spring biased pendulum supported on a vertical plate secured within the casing. The vertical plate also supports the anti-tampering arrangement such that when the indicator is subjected to a preselected impact, the pendulum swings clear of the flag and drops by gravity into a position where it can be observed whereat it is entrapped by the anti-tampering arrangement.

Abstract: A door and discharge hopper combination including a locking mechanism which includes a rotatable latch jaw adapted to engage a keeper on the hopper door. The jaw is maintained in a locked position by means of a link and bell crank lever arrangement which is adapted to be biased into an over-center position to assure positive locking of the latch jaw and keeper arrangement.

Abstract: A safety roller assembly in a plug door for a railway car is disclosed which includes a safety roller traveling in a retaining guide with a recess being formed in the lower support surface of the retaining guide to receive a safety crank connected to the safety roller when the plug door is closed. A safety shoe is provided beneath the safety roller to prevent it from ever falling through the recess in the lower support surface.

Abstract: A sleeping berth for a passenger car compartment includes a tubular bed frame and mattress combination which is hingedly movable between use and non-use positions to a side wall of the car. The bed frame is latched in the non-use position and includes webbing which is spring loaded to urge the bed into the non-use position upon initial movement when raising the berth from a sleeping or use position.

Abstract: A railway car for carrying highway trailers includes an intermediate frame section having a platform for supporting trailer hitches adapted for crane loading operations. The outer ends of the frame are connected to stub sills which include wheel supporting depressed treadways. The associated bolster and bearer structure with the intermediate frame section provides a lightweight trailer hauling car of high strength construction.

Abstract: A sleeping berth movable between stored and use positions includes an elongated pan having a central substantially deep portion and at opposite ends substantially narrower portions which contain a suitably shaped mattress. The shallow portions in the use position of the bed increase the head room for passengers seated on the compartment seats. The pan or shell of the berth also includes at one side thereof a tubular beam construction which houses a linkage mechanism for releasably locking the berth in use and non-use positions.

Abstract: A side dump railway hopper car with outwardly movable discharge doors includes a door operating mechanism including pivoted keeper engaging members adapted to be rotated between lock an open positions. The pivoted keeper engaging members are actuated by linkage mechanism transversely movable by a longitudinally extending movable cam adapted to be supported on the underframe of the hopper car.

Abstract: A locking arrangement for a hopper door includes a rotatable latch which is pivotally connected to rotate between open and closed positions. The latch is actuated by a link and bell crank lever arrangement which also locks the latch closed in an over-center position. The bell crank lever is rotated by a linkage arrangement and biasing means on the bell crank lever holds the same in an over-center position.

Abstract: a closed top railway hopper car of a type which is pneumatically unloaded including a pressure relief valve arrangement which is supported underneath the car between spaced slope sheets of adjacent hoppers. The relief valve arrangement includes a pipe which projects upwardly through a slope sheet into the interior of the car adjacent the upper end thereof. The relief valve is located in a protected V-shaped space beneath the hoppers where it is readily accessable to the operator standing on the ground when pneumatic devices are utilized for discharging the material from the hopper car.
