Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl ammonium chloride) derived from canola oil and/or high oleic safflower oil. Variables that need to be adjusted to maximize the fluidity of vegetable oil based acyl groups include the cis/trans isomer ratio or the Iodine Value (IV) of the fatty acyl groups. The tissue softness is further enhanced by controlling the purity of the fatty acyl groups and the di-substituted versus mono-substituted long chain hydrocarbyl substituent ratio in the quaternary ammonium compounds.

Abstract: The present invention is related to a file server particularly suited for video-on-demand service based on decentralization of files contained in the nodes over a configuration formed by nodes serving a single user or multiple users, each equipped with a magnetic or optical mass memory unit. Such nodes are designed to serve not only their own users but also other nodes of the decentralized file server so that files incoming to the node can be distributed forward to at least two other nodes of the server. A file fetched by several users simultaneously is copied automatically into a plurality of nodes in the file server. This arrangement permits the data transfer rate required from the magnetic or optical memory units to be defined as a constant which is independent from the number of users, mode of use and file server size without any compromise in the performance of the file server.

Abstract: A system is provided for automatically activating a boot-mountable highback between a walk mode and a ride position. In the walk mode, the highback is unrestrained, permitting the boot to flex freely, and consequently allowing the rider to walk comfortably. In the ride position, the highback is tilted toward the toe portion of a boot and prevented from movement in the heel direction beyond a preselected forward lean position, so that leg movement in the heel direction is transmitted through the highback into a gliding board. The highback is adjusted between the walk mode and the ride position simply by stepping into or out of a binding attached to a snowboard. Activation and deactivation of the highback may be achieved through direct or indirect interaction with a board-mounted actuator that may be attached to the binding. A forward lean adjuster may be provided that allows a rider to preselect the amount of forward lean attained when the highback is activated into the ride position.

Abstract: A construction of RTU assembly having a number of independently operational cells for systems functions is provided. Each cell is formed from a configurable component and effectively could be of the same construction as a conventional RTU that would be used for a particular function. There is inter-cell communication for the continuous downloading of information between cells. Ideally the information is controlled in such a way that each cell is aware of all the information that is being transferred, but only receives that information that it requires. In this way all the functions can be performed and the cells operate as equal peers and no one cell has priority over the other cells, such that the failure of one cell will cause the failure of all the others. There can be duplication of function in the cells and various "redundancy" of power, and I/O ports is built into the system.

Abstract: An apparatus and method for slurrying waste materials and drill cuttings. The apparatus includes a pump having a chamber an inlet opening into the bottom of the chamber, an impeller, an outlet on one side of the chamber for removal of material into a discharge line, and circumferentially spaced circulation ports in the chamber side. The impeller extends below the chamber and breaks up debris in addition to drawing material into the pump chamber. The pump may be rotated by a swivel connection and moved and manipulated in the tank by a crane arm, or it may be suspended by cable or other means. The pump stirs up a slurry by rotating the impeller, opening the circulation ports at least partially so that the material entering the bottom inlet to the chamber and being agitated by the impeller is forced out of the circulation ports. The pump can operate in the stirring mode until the material to be removed is generally homogenious, whereupon the circulation ports can be closed allowing the impeller to direct the slurry through the side outlet of the chamber into the discharge line. The stirring or slurrying mode can be combined with a discharge mode by opening the circulation ports as required to slurrify the material while it is pumped out the discharge line. An auxiliary discharge conduit may also be connected with the outlet to discharge material back into the tank to exchange upper fluid layers with lower layers.
