Patent CA-2271061-A1 (CA)
Inventor: TAN NIANXIONG
IPC: H03M1/74
Filed: 1997-10-07
Abstract: High-speed and high accuracy digital-to-analog (D/A) converters find many applications in signal processing. For wideband telecommunication systems, there is a strong demand on high-performance D/A converters. With the design of the present invention it is enabled to prevent distortions and intermodulations for high-speed and high-accuracy digital-to-analog (D/A) converters for telecommunication applications, where the requirements on distortion and intermodulation can be very stringent. By combining segmentation for MSBs and binary weighting for LSBs a high-performance digital-to-analog conversion architecture can be achieved, where a delay for the binary weighted LSBs is used to equalize a delay introduced by segmentation and where all bit switches (14) are clocked with a tree-like-clock distribution network (11). New floor plans for CMOS, BiCMOS and bipolar implementation are thus invented and circuits for CMOS bit switches and current sources are also disclosed.

Patent CA-2290693-A1 (CA)
Title: Hydrocarbon upgrading process
Inventor: DURAND PAUL PIERCE
IPC: C10G69/04
Filed: 1998-05-12
Abstract: Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably in intermediate pore size zeolite such as ZSM-5 to crack low octane paraffins and olefins under relatively mild conditions, with limited iromatization of olefins and naphthenes. This is followed by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumina.  The initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octane. Overall liquid yield is high, typically at least 90 % or higher. Product aromatics are typically increased by no more than 25 wt.% relative to the feed and may be lower than the feed.
