Title: Thermosetting epoxy powder coatings having improved degassing properties
Inventor: RUTH WILLIAM GEORGE
IPC: C09D163/02
Filed: 2001-10-30
Abstract: A clear coat dicyandiamide cured epoxy powder coating for non-metallic substrates wherein the finish coat is visually haze-free as a result of the addition of a small amount of an aromatic substituted urea compound. Non-metallic substrates, such as brass, cannot withstand extremely high temperatures which are required to cure well known powder coatings. However, coating systems which cure at lower temperatures often produce a haze within the finish clear coat. The present invention alleviates this problem.

Title: Red ghosts virtually eliminate delayed reactionto packet loss
Inventor: REYNIER JULIEN J E
IPC: H04L47/32
Filed: 2001-10-30
Abstract: The method for managing multiple flows through a communications de-vice includes maintaining a list of "ghost" flows. Any packet subject to dis-card due to an active queue management scheme like RED (Random Early Detection) is first checked against the ghost list. A non-ghost packet is discarded and a new entry is created in the ghost list. Ghost packets are discarded in proportion to their visibility, initially 1/2. The flow is removed from the list after one round trip time (perhaps when the lost packet is re-transmitted). The ghost list compensates for the delay between the time a packet is discarded and the time the packet's source receives notification of this loss through duplicate acknowledgements and consequently halves its transmission window. This reduces excess packet loss and resulting oscil-lations in the queue size, unnecessary packet delay variation and variable loss rates. The method may include a ghost queue size calculated by under-counting ghost packets for use in any RED scheme. The ghost queue size represents the length of the queue as it should have been if there was no delay.
