Abstract: A tank trailer includes front, rear, and transition sections. The front section has a front frame having a front-frame front end, which is at a front-frame height above a surface upon which the tank trailer rests, and a front-frame rear end. The front section includes a cylindrical front barrel coupled to the front frame and having a front-barrel diameter and a front barrel length. The rear section has a rear frame having a rear-frame front end and a rear-frame rear end, which is at a rear-frame height above the surface, and a cylindrical rear barrel coupled to the rear frame, which has a rear-barrel diameter and a rear barrel length. The transition section includes a cylindrical transition barrel coupled to the front barrel and to the rear barrel and a transition-barrel diameter and a transition-barrel length along a transition-barrel height. The front-barrel diameter is the same as the rear-barrel diameter.

Additionally, the disclosed invention is capable of maintaining a vacuum seal when closed while maintaining intermodal functionality.

Abstract: An improved mobile fluid storage tank having a base, substantially vertical front wall, a substantially rear wall, a pair of substantially parallel side walls and a roof structure. The roof structure has a rear roof portion and a front roof portion. The rear roof portion is substantially parallel with the base and extends along the rear portion of the two side walls while the front roof portion is comprised of a single sloping section which extends from the forward end rear roof portion to the vertical front wall. The intersection of the front and rear roof portions being selected to provide the optimum volume of fluid content of the tank.

Abstract: Containers for liquids, commonly dispensed for consumption at a temperature below ambient (such as chilled soft drinks cans) can be maintained for extended periods below ambient, after they have been dispensed from a refrigerated container, by providing a lining member formed from a plastics material having closed cells and providing insulating properties. The lining member may, for instance, have large cells and be dimensioned to fit within the shell of the container, or can be formed as a layer on the internal surface of the shell of the container.

Abstract: A mobile fluid storage tank having a base, a substantially vertical front wall, a substantially vertical rear wall, a pair of substantially parallel vertical sides walls, and a roof. The roof has a rear roof portion and a front roof portion. The rear roof portion extends across the rearward portion of the side walls, while the front roof portion is comprised of two different portions, a sloped portion and at least a two-stepped portion. The sloped and step portions are substantially parallel to each other. The stepped portion is comprised of at least two steps. The storage tank also has an inclined stairway attached to the front wall and extending from the stepped portion adjacent one side wall downwardly to the base portion adjacent the opposite side wall.

Abstract: A method and apparatus for a vehicle mounted rolloff hoist having a tiltable frame. The apparatus provides a releasable hinge connection at the rear ends of a base frame and a rolloff frame enabling the operator to select a pivot point which provides for ground contact. The apparatus also permits the operator, once the tiltable frame is in a substantially horizontal position, to disengage the hinge point and advance the rolloff frame on top of the base frame in a lateral direction, securing the rolloff frame within the base frame. At that point, the hinge connection is reattached, and the rolloff frame is secured within the base frame. The result is an improved method and apparatus of a vehicle mounted tiltable rolloff trailer which provides for optimum load distribution, stability and clearance requirements.
