Abstract: A computer network for high-speed data communication, has a data transmission cable with a root and at least one leaf node. A signal conversion system (SCS) is attached to the root, and at least one client station is attached to a leaf node. The SCS consists of a transmitter that transmits down-stream data onto said cable in a first frequency band; and a receiver that receives data from said client stations on a second frequency band; wherein said down-stream data includes synchronization and acknowledgement signals. Each client station has a receiver that receives data on said first frequency band, and a transmitter that transmits data on a second frequency band according to synchronization signals received on said first frequency band. 
     The computer network is controlled by a method comprising transmitting downstream from the signal conversion system (SCS) a control signal having synchronization information on a first frequency band, receiving said control signal at client stations, transmitting up-stream from said client stations to said SCS on a second frequency band, the transmission being timed with respect to said synchronization information, and acknowledging on said first frequency band successful receipt by said SCS of said up-stream transmission. 
     The client station's transmission packets may include requests for reserved slots on said second frequency band for subsequent transmissions, and the SCS has a scheduler operable to determine a start time for requested reserved slots, and transmits the start time for the requested reserved slots. The client stations are operable to wait to continue transmission until after waiting for the start time. 
     Other systems and methods are disclosed.

Abstract: A method and ink-jet ink composition are provided for reducing crystallization of Acid Yellow 23 anionic dye in ink-jet ink compositions printed on transparencies and glossy media, both film- and paper-based. The method comprises formulating the yellow ink-jet ink composition in accordance with at least one of the following three conditions: (a) a first condition, wherein the yellow ink-jet ink composition includes about 6 to 9 wt% ethylhydroxypropanediol, about 3 to 9 wt% 2-pyrrolidone, and about 3 to 9 wt% diethylene glycol; (b) a second condition, wherein the vehicle of the yellow ink-jet ink includes a buffer in amount sufficient to maintain the pH of the ink-jet ink within the range of about 5 to 7; and (c) a third condition, wherein the cation of the inorganic salt component of the ink-jet ink comprises calcium ions to the substantial exclusion of magnesium ions. While any or all of the foregoing conditions may be implemented to reduce crystallization in the yellow ink, a combination of the three is particularly efficacious. A narrower embodiment also incorporates two alternative techniques, namely reducing the dye load of the yellow ink to no more than about 3.5 wt% and increasing the thickness of the clear polymeric surface coating of the transparency or glossy media to at least about 12 µm from its typical 10 µm. The solution offered by the present method and ink-jet ink composition is easily and inexpensively implemented and does not sacrifice overall print quality.

Abstract: System for preparing food especially potato and vegetables such as corn, rice and soya into chips or chip-like food for subsequent cooking and human consumption is claimed. The untreated food is processed both externally and internally changing its external appearance and inner consistency. Flavouring is incorporated as required either by adhesion, cohesion, or inter-connection. The resulting chip-like food is safe for transport and fit for human consumption. A suitable assembly to process the raw food has a reservoir through which the flavouring is introduced and discharged through parallel needle probes inserted into e.g. the potato. The potato is then cut to shape by chip-shaped cutting blades in a subsequent process.

Abstract: The invention is an image-medium receiving tray, and a
tray (11) for receiving image medium, and a method for
designing a tray that controls the contouring of sheets of
image medium during reception. The tray has a planar surface
(12) and a curved surface (13). The curved surface is
designed by selecting a series of transverse (15, 16) and
longitudinal (17) curves to define a curved surface that is
generally concave in the transverse direction while also
sloping upward in the longitudinal direction. The combined
concave and sloped shape of the curved surface causes the
leading-edge region of the image medium to transversely
curl and thereby obtain sufficient rigidity to extend
beyond the front end of the tray. In addition, the curved
surface - operating in conjunction with the kickout mechanism
of the device - interacts with sheets of medium in a
way that causes the sheets to land on top of each other
instead of sliding against each other, thereby reducing the
possibility of smearing while at the same time producing a
neat, evenly stacked pile of media.

Abstract: The method involves assigning message channels between a communication system and a supply network, over which mobile communications terminals are connected to the communication system, whereby at least one of the channels is assigned at an activity of a mobile communications terminal. The amount of activities is measured for those communications terminals which have at least one assigned message channel. A status query is performed by the supply network at overstepping of a predetermined amount of assigned message channels. The status query involves only those communications terminals whose amounts of activity, measured in a predetermined period of time, lies under a predetermined value. If the query result indicates a deactivation of the respective mobile communications terminal, the respective assigned message channel is released.

Abstract: A bipolar rechargeable battery (20) comprises a vessel (22, 28, 30) with an insulated liner (24) and an interior region (34) for bulk storage of a gas which serves as an electrode active material. A plurality of cells (36) are nested within the vessel, each including a metallic bipolar cup (38) having a circular base (40) and an integral insulated hydrophobic upstanding side wall (42) of truncated conical shape diverging with increased distance from the base. A positive electrode (46) overlies the base. A dielectric separator (50) separates the positive electrode and a negative electrode (48) sized to fittingly engage the side wall such that any gas generated at the positive electrode must pass through the negative electrode to escape the cell to thereby recombine the generated gas with the active material gas within the cell. The upstanding side wall of each cell is oriented to enable gas passage from each of the cells to the bulk gas storage region. The upstanding side walls of the adjacent cells mutually define a gap (54) enabling gas communication between the adjacent cells and between each of the cells and the bulk gas storage region. A gas screen (54) of porous conductive inert material may overlie the gas electrode, providing an interface between the cell and an adjoining cell in the battery and passage of gas between the bulk gas storage and the gas electrode current collector.
