A method and apparatus for supplying bulk material to an end user includes the step of providing a bulk material source that is at a location distant from the end user and a specially configured vessel and trailer apparatus for transporting the bulk material to the end user. The vessel is filled with bulk material at the bulk material source and then transported with a specially configured trailer. Alternatively, at source or destination, the vessel can remain as a temporary storage device, free-standing from the trailer. During transport between the bulk material source and the end user, the vessel is filled or partially filled with a selected bulk material. During transport, the vessel is in a generally horizontal position, supported by the trailer and a specially configured elevator. The vessel is unloaded from the trailer by moving the vessel longitudinally along the trailer and by transferring the vessel from a generally horizontal position upon the trailer to an elevated upright position.

Method and apparatus for installing a liner material into a host conduit such as, e.g., a sewer pipe, hydrocarbon pipeline, gas line, water line, industrial chemical pipe, or a saltwater line. The liner material may include a compression liner and / or a preliner that is attached to the inner wall of the host conduit to repair or reinforce the host conduit or separate the host conduit from materials transported within the new liner formed from the liner material. Curable resin, slurry, or cement can be placed between the liner material and the host conduit to affix the liner material into place. Before and during curing, a fluid such as air or water can be used to inflate the compression liner outwardly toward the host conduit. Spacers positioned between at least a portion of the liner material and the host conduit may be used to (i) calibrate the thickness of the liner material and curable material that is cured to form the new liner, and (ii) form communication channels adapted to house devices such as wire, cable, fiber optic cable, telephone lines, power lines, etc. The spacers and channels can be selectively inflatable to various sizes to allow calibration of the liner thickness and to form communication channels having a selected width or height. Additionally, the liner material may be formed into a one-piece, tubular lining member having an inflatable enclosure defined between an inner and an outer layer of the lining member. The enclosure can be selectively inflated to (i) calibrate the resulting thickness of the cured liner material, and (ii) form communication channels running along the length of the host conduit.

To provide a paper recycling device capable of recycling paper of increased whiteness level that can be widely used for applications other than paper for newspapers, the paper recycling device of the present invention has a dry type defibrator for crushing and defibrating paper, a first transport pipe for transporting defibrated material that was defibrated by the dry type defibrator, a cyclone for air classifying and deinking the defibrated material transported by the first transport pipe, a second transport pipe for transporting the defibrated material that was deinked by the cyclone, and a paper forming machine for forming paper with the defibrated material transported by the second transport pipe.

A bulk material transport vehicle access structure includes an elongated service platform for workers which is pivotally supported at its opposite ends to cantilever arms on parallel horizontal axes to avoid binding between the roller carriages of the cantilever arms and a pair of support pillars. The floor of the platform includes a walkway and a doorway covered by a plurality of side by side doors which may be selectively opened. Electric controls are provided to automatically stop operation of the power means used to control the elevation of the cantilever arms should the service platform become tilted a predetermined extent. Electric controls are also provided to stop lowering of the service platform when it reaches the top of a bulk material transport vehicle.

A materials transport container having a floor and two opposed upwardly extending side walls and a front wall. The container is supported to enable tilting for unloading of material from a rear end. The container has a substantially continuous and smooth hard faced surface on a rear portion of the floor adjacent the rear end to enhance sliding of its load over the smooth hard faced surface. Additionally arcuate surfaces bridging a junction between one or more of the front and side walls and the floor of the container to reduce hangup of material. The arcuate surfaces are smooth hard faced surfaces. The hard faced surfaces are provided by removable wear plates with gaps between then to allow flexion and ease of removal. It is found with use these hard faced wear plates become polished and greatly assist with the removal of material from the transport container.

Systems and methods for providing multimedia content from one process or component to another process or component over an unsecured connection are provided. One embodiment includes obtaining the cryptographic information, extracting the at least partially encrypted video data from the container file to create an elementary bitstream, enciphering the cryptographic information, inserting the cryptographic information in the elementary bitstream, providing the elementary bitstream to a video decoder, extracting the cryptographic information from the elementary bitstream at the video decoder, deciphering the cryptographic information, decrypting the elementary bitstream with the cryptographic information and decoding the elementary bitstream for rendering on a display device using the video decoder.
