Title: Hydroxyl-protecting groups orthogonally removable by reduction and their use in the chemical synthesis of oligonucleotides
Inventor: URDEA MICHAEL S
IPC: C07H19/073
Filed: 1991-07-24
Abstract: Hydroxyl-protecting groups orthogonally removable by reduction with a liquid reducing agent are disclosed. The novel hydroxyl-protecting groups are particularly useful in the chemical synthesis of linear and branched oligonucleotide structures, as they are readily removed from the protected molecule with mild reagents such as dithionite. Examples of such hydroxyl-protecting groups include the 2-methylene-9,10-anthraquinone (Maq) carbonate ester and the p-nitrobenzyl carbonate ester.

Title: Method of operating an automotive type internal combustion engine
Inventor: HAVSTAD PETER H
IPC: F02M25/07
Filed: 1993-02-03
Abstract: ABSTRACT        A method of operating an automotive type internal combustion engine to improve the efficiency and power, fuel economy, and emission control is obtained by phase shifting of both the intake and exhaust valve timing schedules or events, coupled with the use of reed valves in each intake port to restrict the backflow of exhaust gases into the intake port, and essentially unthrottled operation except where necessary to maintain engine stability, the reed valves also providing for a controlled internal EGR system.  The phase shifting and use of intake reed valves will optimize the intake and exhaust event timing at the four major engine operating conditions of idle speed, part load, and wide open throttle low speed and high speed operation.

Patent CA-2099031-A1 (CA)
Inventor: AHMADI HAMID
IPC: H04L12/56
Filed: 1993-06-23
Abstract: In a packet communications network, the addition or deletion of a connection to the network by a user is governed by a link traffic metric which represents the effective capacity of each link in the network which participates in the packet connection route. The link metric is calculated in real-time and updated by simple vector addition or subtraction. Moreover, this link metric is also used to calculate leaky bucket parameters which govern the access of packets to the network once the connection is set up. A packet network using these link metrics and metric generation techniques provides maximum packet throughput while, at the same time, preserving grade of service guarantees.

IPC: G01S7/52
Filed: 1994-05-13
Abstract: A volume flow meter for displaying two-dimensional volume flow through a vessel, comprising an ultrasound instrument with scan head, a location and orientation sensor mounted to the scan head, and a computer connected to the ultrasound instrument and the sensor. The scan head is adapted to be positioned adjacent the vessel under investigation, for generating a raster of pixels which defines a colour image representing flow velocities in the vessel through an image plane of the scan head.      The sensor measures position and orientation of the scan head in three dimensions and generates a signal representative thereof to the computer. The computer receives said raster of pixels and the signal from the sensor and in response calculates the position and orientation of the vessel axis in three-dimensions responsive to orientation of the image plane longitudinally of the vessel. The computer then determines an angle a between this axis and the image plane responsive to orientation of the image plane transversally to the vessel. Finally, the computer calculates and displays the volume flow as a summation of the flow velocities scaled by the tangent of the angle e.
