Title: Container with expandable side walls and method
Inventor: LESMEISTER JEROME R
IPC: B65G67/04
Filed: 1995-05-31
Granted: 2003-12-30
Abstract: A container, such as a transfer trailer, a roll-off container, or other container that can be transported, has expandable side walls. The walls are hydraulically, or otherwise, forced outward to increase the inside width dimension of the container. A loading device, such as a garbage route collection truck or other similar vehicle can then be backed into the container whereby the solid material waste or other commodities can be directly loaded into the container, Once the container has been loaded, the side walls can be retracted to their original positions, such that the container maintains its standard regulated width dimension.

Granted: 2004-05-11
Abstract: A method of forming a metal-to-metal seal in high pressure applications with low contact stress. Firstly, providing a first elongate pressure containment member having a surface of revolution. Secondly, providing a second elongate pressure containment member having an exterior surface, an interior surface, a remote end, and a thin walled extension sleeve having a first end and a second end. The first end of the thin walled extension sleeve is conjoined with the second elongate pressure member at the remote end.      The second elongate pressure containment member is of a greater thickness than the sleeve. Thirdly, coupling the first elongate pressure containment member and the second elongate pressure containment member with the sleeve positioned in close relation to the surface of revolution.      Fourthly, placing the first elongate pressure containment member and the second elongate pressure containment member in an environment in which fluid pressure tends to cause a flow of fluids from the second end to the first end of the sleeve along an interfacial region between the sleeve and the surface of revolution. Fluid pressure tends to constrict and set up a pressure gradient which promotes sealing along the interfacial region.

Abstract: A web processor includes a support for supporting a movable web to form a concave trough along a path having a longitudinal axis. A rotatable element is provided which includes a beam redirecting device for redirecting an incident beam of radiation to produce a resultant beam directed substantially orthogonally to the axis of rotation of the rotatable element. The rotatable element includes at least one lens for focussing the resultant beam to produce a focus point on the path. The path is configured such that rotation of the rotatable element locates the focus point on a line non-parallel to the longitudinal axis of the concave trough. In a method for treating a web, a movable web is formed into a concave trough having a longitudinal axis. An incident beam of radiation is directed to a beam redirecting device on a rotatable element to produce a resultant beam of radiation directed substantially orthogonally to an axis of rotation of the rotatable element. The resultant beam is focussed to produce a focus point on the concave trough. The web is moved in a direction along the longitudinal axis while rotating the rotatable element to locate the focus point on a line across the web, with a path of travel of the focus point being non-parallel to the longitudinal axis of the concave trough. A web is scored, marked, perforated or cut by the above method.
