Abstract: Disclosed a thermal- and sound-insulating container having a chamber, which is defined by multilayer wall structure including vacuum layers therein. The chamber is made as small as possible the surface area thereof to achieve the high insulating effectiveness. The thermal- and sound-insulating container is comprised of the multilayer wall structure with vacuum layers therein, which constitutes the chamber defined in a hollow cylinder partially having a flat secant face, the hollow cylinder having a cross section of a circle or an ellipse that closely resembles the circle. The multilayer wall structure is composed of a pair of confronting frames arranged spaced away from each other, surface panels attached to the frames to define an empty space between the confronting frames, and sealing members arranged between the frames and the peripheries of the surface panels so as to keep the space at vacuum.

Abstract: An arrangement of a track laying combat vehicle towing a trailer utilizes a curved rail affixed to the aft end of the combat vehicle and generally tered about a vertical axis passing near the volumetric center of the combat vehicle. The hitch connection between the combat vehicle and the trailer includes a wheeled carriage that rides on the rail. Because of the rail and carriage, the outward swing of the combat vehicle aft end, which is in the opposite direction from the combat vehicle's turn direction, do not appreciably affect the trailer.

Abstract: A fuel tank for a trailer including a tank that is adapted for securement to an underside of a trailer. The tank has a generally trapezoidal configuration with a top face and a bottom face. The top face has recesses formed therein for receiving cross members of the trailer therein. The top face has a filling port in communication with an interior of the tank. A dispensing nozzle is in communication with a fuel pump disposed within the interior of the tank. A deflector shield is secured to the underside of the trailer forwardly of the tank. The shield is dimensioned for covering a forward portion of the tank.

Abstract: A towable, auxiliary fuel tank designed to transport a supply of fuel, so that a towing vehicle is able to consume the fuel present in the tank, thus extending the range of the vehicle. A ring is affixed to the trailer of the tank so that it may be connected to a vehicle. Attached to the vehicle is a hitch with a channel extending across a recess and a pin slidably mounted therein. The recess of the hitch is designed to hold the ring when the pin is closed, thus connecting the auxiliary tank to the vehicle. A lever is attached to the pin so that the ring may be connected and disconnected from the hitch. A cable is also attached to the pin and extends to a handle within the interior of the vehicle. When this handle is operated, the pin is moved from across the recess, thus unlocking the auxiliary tank from the vehicle. Fuel is transported from the auxiliary tank to the vehicle via a hose that is connected to both the auxiliary tank and vehicle. A securing device is provided to secure the hose to the vehicle.

Abstract: A bulk material transport apparatus, such as a truck or trailer, having at least one bulk material pressure vessel mounted thereon. The pressure vessel is provided with at least one sealable hatch opening, a first port and a second port all of which are offset from the apex of a torispherical top portion of the pressure vessel. The pressure vessel is provided with at least one discharge port located in a toriconical bottom portion thereof and is also provided with air inlet means for introducing pressurized air into the vessel. An operator platform being positioned at a preselected distance from the offset hatch opening and being within such proximity of the offset hatch opening so as to enable an operator positioned on the operator platform to gain access to the interior of the pressure vessel through the hatch opening is provided.

Abstract: A trailer vehicle for distributing a fertilizing manure slurry to a field which includes a slurry distribution assembly mounted to the rear of the vehicle having four slurry distribution units, each with three plow teeth and a slurry distribution nozzle associated with the teeth for feeding the slurry at root level in the soil. The distribution assembly includes an elongated manifold with four flexible conduits extending from the manifold to each nozzle on the distribution units. The manifold communicates with the slurry tank. The trailer vehicle can also have a special suspension to maintain the tank relatively level. The trailer has three sets of wheels which are articulated in tandem, and the rear wheels of the trailer can be steered in the arc traced by the motive vehicle pulling the trailer.

Abstract: An agricultural tank wagon is provided for attachment to a tow vehicle. The tank wagon comprises front running gear, rear running gear, a first coupling assembly pivotably coupling the rear running gear to the front running gear, a wagon tongue for attachment to the tow vehicle, and a second coupling assembly pivotably coupling the wagon tongue to the front running gear. The front running gear includes a front axle defining a central axis of rotation The rear running gear cooperates with the front running gear to support the tank. The first coupling assembly operates to pivot the rear running gear relative to the front axle about a first pivot axis that is offset from the central axis of rotation. The second coupling assembly operates to pivot the wagon tongue relative to the front axle about a second pivot axis lying in substantially parallel offset relationship with the central axis of rotation.

Abstract: A system for on-site recovery of reusable industrial waste components, such as solvents, from a liquid waste stream includes a trailer that is internally partitioned to separate system components through which the waste stream passes in a first partitioned section of the trailer from support and control components in the second trailer section. Input waste is fed into a horizontal thin-film evaporator within the first trailer section, while steam is fed in a closed loop through the evaporator from the second section of the trailer for evaporating volatile solvents in the waste stream, and thereby separating the volatile solvents from non-volatile liquid and solid components of the waste stream. The evaporated volatile solvents are fed to a heat exchanger, again enclosed within the first partitioned section of the trailer, for recondensation through heat exchange with a coolant fed to the heat exchanger in a closed loop from the second trailer section.
