A tanker truck offloading manifold method. The tanker truck offloading method includes detecting a tanker truck in at least one of a plurality of offloading stations, energizing a blower having an inlet duct coupled to a tank receiving fluid from the plurality of offloading stations, the blower to draw gasses from the tank when at least one tanker truck is offloading at least one of the plurality of offloading stations, de-energizing the blower when no tanker truck is offloading at any of the plurality of offloading stations, energizing a pump having an inlet coupled to the tank when the tank level is above a predetermined high level, and de-energizing the pump when the tank level is below a predetermined low level.

A silo transport system includes a vehicle and a silo configured to store material when in a vertical orientation supported on the ground surface, and to be transported in a horizontal orientation on the vehicle. The vehicle includes a pivoting cradle supporting the silo in the horizontal orientation and a lock to releasably attach the cradle to the silo. A cradle controller pivots the cradle from a lowered position to a raised position where the silo is in the vertical orientation resting on the ground surface. When the cradle is attached to the silo, the cradle controller pivots the cradle away from the raised position to the lowered position when the silo attached to the cradle is empty, and is inoperative to pivot the cradle away from the raised position toward the lowered position when the silo attached to the cradle contains greater than a threshold amount of the material.

A vehicle includes at least one hose extending from the vehicle and configured to extend below ground through a manhole, and a light system. The light system includes a storage member, such as a retractable reel, coupled to the vehicle, a flexible line wrapped at least partially around the storage member, and a light source coupled to the flexible line. The storage member is adapted to selectively extend and retract the light source together with the hose below ground, and the light source is storable on the vehicle adjacent the storage member. The light source has a self-contained power source. In some systems, the flexible line and/or the light source are removable from the vehicle so they can be moved to a remote location from the vehicle.

A computer-controlled motorized pump system is provided. A generator is mechanically connected to a power takeoff. A first controller receives AC power from the generator and converts the AC power to DC power and provides DC power to a computing system that has one or more processors and one or more computer-readable hardware storage media and a user interface. A second controller is directly coupled to the first controller and provides AC power to a motor. The motor is mechanically connected to a pump, and the motor is in communication with, or controlled by, the computing system.

This abstract is based on an alternate, improvement control method, to assist the drivers who have had, or recently discovered they have hand or finger disabilities and can no longer use our easy grab ball control disc, because it is too difficult for them to pull against some of the low-end spreader models that use very heavy springs to keep the tow-behind spreader center-column-handle-lever in place, each time the slide gate porthole chute is repositioned.

This alternate control method consists of two (2) improved modified control discs, that incorporates (fulcrum pivot mechanics) to be used in the event the operator's hand has arthritis, carpel tunnel, difficulty in closing fingers, fist, or other hand deficiencies, which makes them unable to pull and use our original twine line grab ball control disc, against the heavy force of those springs installed by the manufacturer.

These two (2) improved fulcrum-pivot-design controls will make it very easy for the driver to still open and close the slide gate porthole chute from the d river's seat, because they use (fulcrum physics) less force to move a heavier load.

A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.

A wheeled manure-removal vehicle for removing manure from an animal-shed floor includes a tank for storing manure, a manure collector, a liquid reservoir placed in the tank and having an opening for the supply of liquid to the reservoir and the discharge of liquid from the reservoir, and a flexible reservoir wall, to make it possible to vary the volume of the reservoir, depending on the fill level, and a dispenser operatively connected to the reservoir for dispensing liquid from the reservoir onto the animal-shed floor. The opening of the reservoir is situated in a top part of the reservoir. The reservoir furthermore includes a spacer which extends on the inside of the reservoir from the opening down to the lower part of the reservoir to ensure a liquid passage between the opening and a bottom part of the reservoir.

A wheeled manure-removal vehicle for removing manure from an animal-shed floor includes a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor. The scraper assembly includes a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body. The rolling body extends on a side of the scraping element which faces away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together, and has, on the side facing the scraping element, a rolling surface which is convexly rounded towards the scraping element. The use of the rolling body for contact with the scraping element has an advantageous effect on the life of the scraping element on the vehicle.

A dry bulk tank and a method of carrying a load and discharging a load therefrom. The dry bulk tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.
