Abstract: A novel transport architecture and network elements use nodes in a ring or virtual ring configuration. Information is exchanged among the nodes in a continuous series of containers carried in a superframe. A container is assigned to a destination node and is divided into partitions which are allocated for source nodes. Therefore, when a container destined to a particular destination node arrives at a node and if this node has information to send to the destination node, it fills the allocated partition within the container with information destined to the destination node. The sizes of the superframe, containers and partitions are all variable dynamically or statically.

Abstract: This invention provides a method for invisibly tagging, for subsequent identification purposes, various liquid petroleum hydrocarbons, such as crude oil, diesel fuel, heating oil, kerosene, lubricating oils, waxes, jet fuel, and in particular gasoline, remarkably using visible dyes by incorporating therein one or more visible dyes at minute levels such that they cannot be visually detected by the human eye. Visible dyes which have high solubility in petroleum hydrocarbons and maximum absorption in the 550-700 nm visible wavelength range are used to impart such invisible markings. The visible dyes, although employed at non-visible levels, are still capable of detection in a relatively quick and simple manner which requires minimal instrumentation, creates no waste products for disposal, and gives true quantitative results of dye concentrations in the field. This invention, therefore, further provides a method for so identifying the tagged petroleum hydrocarbons by exposing the tagged hydrocarbon to visible light having wavelengths in the portion of the spectrum utilized and detecting and quantifying the presence of the dyes in the tagged product from their characteristic absorption with available absorption detection equipment sensitive in this spectral region. This invention also provides visible dye compositions particularly appropriate for said invisible tagging.

Title: Disc tumbler lock and key
Inventor: BLIGHT BRIAN
IPC: B23C3/35
Filed: 1998-08-10
Granted: 2008-04-01
Abstract: A tubular lock of the kind having a body and a barrel assembly which is mounted within the body for relative rotation about an axis. The assembly includes a tubular sleeve (4) and a number of disc tumblers located within the sleeve (4) so that each is rotatable relative to the sleeve and relative to one another about the axis. A side locking bar (9) is operative to prevent rotation of the assembly relative to the body, and that bar is rendered inoperative by insertion of a correct key into the lock keyway. The disc tumblers rotate in response to insertion of a key into the keyway and include a number of standard tumblers and a special tumbler. The locking bar (9) is inoperative when each standard tumbler is at a service position of rotation and the special tumber is at either a service position or a second function position of rotation. A service key (20) is operable to place all tumblers at the service position, and a special change key is operable to place the special tumber at the second function position and to place all other tumblers at the service position. When the special tumbler is at the second function position it releases a movable detent (23) which is otherwise operative to prevent axial removal of the assembly (2) from the body. But such removal is not possible until the change key is turned to rotate the assembly to a position at which a fixed detent (28) is aligned with a longitudinal groove (33) of the body. The key (20) is formed by use of a computer controlled machine which enables selection of any one of a number of key forming operation sequences, each of which produces a key (20) having characteristics to suit a particular lock.

Abstract: Use of an RF repeater operable with a CDMA cell base station and collocated with, or located near, an offending base station reduces the effects of interference in the CDMA cell generated by the offending base station and improves communications between the CDMA base station and its subscriber stations which are operating near the offending base station. Out-of-band emissions or intermodulation products (interference) generated by the offending base station (utilizing CDMA, FDMA, TDMA or other type of technology) and falling within the frequency bandwidth of the CDMA channel cause interference with CDMA subscriber stations operating near the offending base station thereby preventing establishment or maintenance of a communications link with the CDMA base station. By deploying an RF repeater at or near the offending base station, the effects of said interference is lessened or reduced thus increasing the coverage area of the CDMA cell. A second RF repeater operable with the offending base station and collocated with, or located near, the CDMA base station may also be used to reduce the effects of interference (or the interference itself) in the CDMA cell generated by offending subscriber stations operating near the CDMA base station. In addition, use of one or more RF repeaters also improves communications between the offending base station and its offending subscriber stations by reducing the effects of interference (or the interference itself) generated by the CDMA base station (upon the offending subscriber stations) and the CDMA subscriber stations (upon the offending base station).
