Abstract: Certain mixtures of cyclodextrin derivatives, which were synthesized in mild ly basic conditions, can be separated into mixtures that crystallize easily and mixtures of similar composition, which remain amorphous. Thus, it is possible to obtain the particular advantages of crystalline and/or amorphous state components from one reaction product. Both crystalline and amorphous components of the product have good ability to form inclusion complexes.

Abstract: A system and method for a communication terminal to manage memory and maintain a current application version for multiple applications are provided. The system and method provide for managing memory in a communication terminal coupled to a server device enabling the communication terminal to provide memory capacity for storing in a memory and executing on the communication terminal a plurality of applications downloaded from the server device. Prior to downloading an application, the communication terminal determines an amount of memory capacity required by an application client to be downloaded from the server device. The communication terminal then attempts to allocate the memory capacity. If memory cannot be allocated from the system heap, the communication terminal purges data contained in the memory according to a dynamic list of priorities to create memory capacity in the memory for the application client. Once sufficient memory capacity has been created, it is allocated to the application client, and the application client is downloaded to the communication terminal.

Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells, abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.

IPC: C40B50/00
Filed: 2000-10-10
Granted: 2008-03-18
Abstract: A method and device are provided for simultaneously creating a plurality of identical micro-arrays of biological samples. The invention utilizes a plurality of substrates, each of which having a top side, a bottom side, and a pattern of through-holes. Each through-hole has a wider upper cross-section, a narrower lower cross-section, and a step or plateau formed in the transition area. When the substrates are stacked, through-holes are in registry and form tunnels extending through the stack of substrates. Reagents of interest are caused to flow through the tunnels and deposit on the step or plateau area. A  barrier layer may be provided to prevent leak-through between neighboring holes. After the desired reagents have been deposited, the substrates are separated. In this manner a series of micro-arrays, each capable of containing hundreds or thousands of biological samples such as cDNA fragments, is formed simultaneously.

Title: Method of making plastic asphalt paving material and paving material and pavement made thereby
Inventor: FISHBACK GARY M
IPC: C08L95/00
Filed: 2001-11-30
Granted: 2011-10-11
Abstract: An asphaltic concrete or paving material (10) is produced that contains from about 5 percent or more, and up to about 20 percent, activated granular recycled plastic (22), which supplements or replaces rock aggregate (21) in the mixture. The source plastic (31) may include mixed residual classes of recyclable plastic, including thermosetting plastics and other plastics having little to no widespread utility. The paving material (10) produces roadbeds (12) of higher strength and durability, requiring less total asphalt thickness and providing greater water impermeability. The recycled plastic component (31) of the material is a mixture of any and all recyclable classes 3 through 7, or of those materials from such classes remaining after potentially more valuable recyclable materials may have been selectively removed. The paving product (10) is preferably formed by a process of shredding or mechanically granulating used and industrial waste plastic to a no.4 to 1/2 inch sieve size, and to 1/4 inch to 3/8 inch granules. The Plastic may be cooled during the granulating process. The granules are then treated with an energized activating medium, a plasma formed in preferably argon or some other plasma enhancing gas (93), to activate the surface of the granules, without burning or melting the plastic- Humidity free gas, from a dehumidifier (79) or other source, fills voids in the particle mass fed to an input hopper (82) or otherwise to the top of a vertical plasma column (81) having the argon flowing upwardly therethrough. A replaceable plastic liner (98) protects the column walls from deposits. Gas bursts prevent clogging of the particles in the column. The activated treated granules are added to the aggregate then mixed with the asphalt binder to produce the paving meterial. A slurry or sands mix of plastic and binder may also be applied over an aggregate layer, base layer or roadbed.

Abstract: The present invention relates generally to a method for the generation of a substantially homogeneous population of undifferentiated cells. More particularly, the present invention relates to the purification of a substantially homogeneous population of stem cells and their progenitor or precursor cells. Even more particularly, the present invention provides a population of neural stem cells (NSCs). The subject invention is particularly directed to NSCs and precursor cells with the capacity to differentiate into cells and cell lineages required for the development, maintenance or repair of the central nervous system in an animal such as a mammal. The present invention is further directed to NSCs and progenitor and/or precursor cells which are capable of proliferation and differentiation into multiple cell lineages, such as but not limited to neurons, oligodendrocytes, glia and astrocytes. The subject invention further contemplates the use of NSCs and/or precursor cells for the repair or regeneration of tissue, such as tissue associated with the central nervous system, in an animal including a mammal. The NSCs of the present invention may be used to identify naturally occurring molecules such as cytokines as well as molecules obtained from natural product screening or screening of chemical libraries which induce proliferation of the NSCs. Such molecules are useful in the development of therapeutics.

Abstract: A method, system, and apparatus for a management station to manage a node cluster in a computer network. Regardless which node in the node cluster receives a management command from the management station to the master node, the management command is sent to the master node. The master node prepares a command response and sends the response back to the original node that received the management command. The original node, in turn, forwards the command response to the management station. The invention utilizes management agents executing on a master node and servant nodes to create and process the command response.
