Title: Method of and device for recording information
Inventor: VAN GESTEL WILHELMUS J
IPC: G11B20/10
Filed: 2000-07-12
Abstract: A method is described for writing real time video signals on an optical disc  (2) having a recording area (40) which comprises an administrative area (43) , a spare area (42), and a user area (41). Normal recording takes place in blocks (45) in a first pre-reserved area (NW) of a free part (47) of the use r area (41). If during the recording process a defective block (45*) is encountered a replacement recording having the size of a plurality of blocks  is made in a second pre-reserved area (RW) of the free part (47) of the user  area (41), after which normal recording continues in the first pre-reserved area (NW). On the one hand, this limits the number of jumps for replacement recording and, on the other hand, it results in the storage capacity of the disc (2) being used very efficiently.

Inventor: GIBSON MARK
IPC: H04L12/56
Filed: 2001-06-27
Abstract: In a label switch communications network, a third level of label is employed in conjunction with a dynamic multiplex constraint-based routed label switched path (CR-LSP) in order to achieve implicit switching at nodes within the network.  Implicit switching occurs when a switching function takes place at a node without the need for any control function being required at that node. A three-layer label stack provided at the edge of the network achieves end-to-end connection oriented behaviour with guaranteed Quality of Service. The use of the three-layer label stack concentrates the control of the network to the two edges of the network and a single central switching stage of the network.

Filed: 2001-09-13
Abstract: The plant, comprising a high-pressure column (101), an intermediate pressure column (102) with a boiler (24), and a low pressure column (103), has no means for argon enrichment of a fluid containing between 3 and 20 per cent/mol of argon other than the three aforementioned columns. During operation a mixture of at least oxygen, nitrogen and argon is fed into the high-pressure column, where it is separated into oxygen-rich and nitrogen-rich fractions. Part of both fractions is fed to the low-pressure column, which operates at preferably above 4 bars, and the gas from the lower part of this column is sent to the boiler in the intermediate column and at least partially condensed before being returned to the low-pressure column. Oxygen-rich and nitrogen-rich fluids (31, 72) are then drawn from the low-pressure column; at least part of the nitrogen-rich fluid is at least partly condensed in a vaporizer/condenser linked to the low-pressure column, and at least part of the partly condensed fluid is fed back to the high-pressure column, but no fluid containing 3-20 per cent/mol of argon is enriched with argon in any column apart from the high-pressure, low-pressure or intermediate-pressure columns. An Independent claim is also included for the instillation for the cryogenic air separating procedure.

Abstract: A first voussoir for use in an arched structure between second and third voussoirs includes a first end bearing surface with a protrusion which extends from the surface and which is mateable with a corresponding recess in an abutting end bearing surface of the second voussoir. The second end bearing surface includes a recess in the surface which is mateable with a corresponding protrusion in an abutting end bearing surface of the third voussoir. Preferably the protrusions and the recesses have both longitudinal and transverse components of structure. A lug is secured to the first voussoir for connecting one end of an associated mooring cable to the first voussoir while an opposed end of the cable is connected to an associated mooring positioned at a distance away from the horizontal span of the arched structure. Arched structures comprising a plurality of such voussoirs may be constructed by successively positioning individual ones of the voussoirs in arching abutment to form a segment of the structure, then positioning a keystone. During construction, individual voussoirs may be moored to associated moorings to avoid the need for underlying shape support. After construction, they may remain moored to impart added stability to the structure.

Title: Organic electroluminescent device
Inventor: HOFSTRA PETER G
IPC: H01L51/52
Filed: 2000-07-21
Abstract: The present invention provides a novel organic electroluminescent device having an optical interference member which reduces the overall reflectance from the device. The invention is particularly suited to current-driven organic displays having an anode, an electroluminescent layer and a cathode,  where at least one optical interference member is placed between two of the layers and thus forms part of the electrical circuit required to excite the display. The optical interference member is chosen to have a thickness which  causes at least some destructive optical interference of ambient light incident on the display. In addition, the material(s) of the optical interference member are chosen to have a work function which is compatible with the highest occupied molecular orbital, or the lowest unoccupied molecular orbital of the electroluminescent layer, depending on the location  of the optical interference member in relation to the anode, cathode and electroluminescent layer. The appropriate selection of material can ensure proper current flow through the device, thus reducing the likelihood of electrical breakdown of the organic electroluminescent layer, and improving the overall energy efficiency of the device.
