Title: Disposal of material containing antimony and vanadium as landfill
Inventor: PITTS FRANK
IPC: A62D101/43
Filed: 1993-04-29
Abstract: An FCC catalyst contaminated with antimony introduced into the FCC cycle as a means to passivate metals such as vanadium contained in gas oil feedstock is treated to reduce the leachability of antimony, as well as vanadium and other metals if present in appreciable amount, thereby rendering the material suitable for disposal as landfill.

Patent GB-2280925-A (GB)
Title: Laminated glazing panel with area of different mechanical property
Inventor: CHINZI CALOGERO
IPC: C03C27/12
Filed: 1994-08-05
Abstract: A glazing assembly is described, suitable for use as an emergency escape, comprising a laminated panel having at least two sheets (10, 12) of vitreous material adhered to a polymeric intervening layer (14) which extends continuously between said sheets (10, 12). In at least one minor area zone of the panel, the possibility of elongation of the intervening layer (14) under the influence of mechanical stress when said at least two sheets (10, 12) of vitreous material are broken, is different compared with the possibility of elongation of said intervening layer (14) over the rest of the panel, for example by providing a line of adhesive tape 16 secured to the inner face of glass sheet 12. The assembly may be used in vehicles, such as in high-speed train carriages. When there is a need to break through the panel for emergency escape purposes, the panel is subjected to a suitable mechanical force, the intervening material (14) is more easily torn or cut away, thereby enabling faster escape. The invention thereby enables easy escape through a window space while maintaining the security performance of the assembly at a satisfactory level. <IMAGE>

Title: Communications cell scheduler
Inventor: DELP GARY SCOTT
IPC: H04L12/56
Filed: 1998-03-05
Abstract: A method and apparatus are provided for scheduling the transmission of cells of a plurality of data streams in a communications network. A best effort scheduler is provided for scheduling the transmission of cells of a plurality of data streams in a communications network. The best effort scheduler includes a best effort operational mode and can include more than one timing wheel. When the best effort scheduler includes more than one timing wheel, then the priority of the best effort timing wheel is lower than the priority of the other timing wheel or wheels. Data of each data stream is enqueued to a corresponding data cell queue. A target next transmission time for each data cell queue is calculated utilizing predetermined logical channel descriptor parameters. A lower priority or a higher priority timing wheel is selected and a timing wheel time slot is calculated based on an identified target transmission time for each active data cell queue. An active indication is set for the identified timing wheel time slot and an entry is stored to point to the corresponding data cell queue for the identified timing wheel time slot. The relative rates between data streams are maintained, while the absolute rates of the data streams are increased or decreased in the low priority wheel. Scheduling opportunities can be defined utilizing a predefined pseudo data cell queue. Then the calculation of the target transmission time for each data cell queue includes the predefined pseudo data cell queue, and the identified target transmission time for the predefined pseudo data cell queue defines scheduling opportunities of multiple timing wheel time slots.
