Title: Modified proteins and methods of their production
Inventor: NOREN CHRISTOPHER J
IPC: C12P21/06
Filed: 1996-06-19
Granted: 2008-10-28
Abstract: The present invention is directed to modified proteins and methods of their production. The modified proteins comprise a controllable intervening protein sequence (CIVPS) inserted into a target protein, the CIVPS  being capable of excision from or cleavage of the modified protein under predetermined conditions in cis or in trans, i.e., increase in temperature, exposure to light, unblocking of amino acid residues by dephosphorylation, treatment with chemical reagents or deglycosylation. If desired, the modified protein can be subjected to these conditions. The CIVPS may also be inserted into a region that substantially inactivates target protein activity.

Title: Process for preparing purine derivatives
Inventor: DVORAK CHARLES A
IPC: C07D473/00
Filed: 1997-01-21
Granted: 2006-08-15
Abstract: Process and novel intermediates for preparing the L-monovaline ester of 2-(2-amino-1,6-dihydro-6-oxo-purin-9-yl)methoxy-1,3-propanediol (see above formula) and its pharmaceutically acceptable salts. The present process and intermediates provide for reduced impurities in the monovaline ester end-product, also eliminating the costly and time consuming purification step and allowing the use of starting materials of lower purity, which, in turn, reduces overall production costs. The products are of value as antiviral agents with improved absorption.
Patent CA-2246922-C (CA)
Inventor: GAMBETTA DAVID L
IPC: F16K3/16
Filed: 1998-09-09
Granted: 2007-12-11
Abstract: A knife gate valve is constructed of two body members bolted together about a resilient gate seat. The two body members and the resilient gate seat include sets of axially aligned bolt holes through which machine bolts extend. Matching flanges on the body members form a recess for receiving the resilient gate seat, thereby constraining its movement and preventing its deformation when the knife gate is closed. The matching flanges also facilitate the uniform tightening of the machine bolts during gate valve assembly. The resilient gate seat includes tab portions at its ends for improved retention and rib portions along its length for improved sealing. The resilient gate seat includes a seating contact area that has a width that is less than the thickness of the knife gate for reducing friction between the knife gate and the gate seat.
Patent CA-2248055-C (CA)
Inventor: DINGSOR ANDREW D
IPC: H04B1/40
Filed: 1997-05-05
Granted: 2004-10-26
Abstract: A method, apparatus and article of manufacture for compensating for carrier frequency error is disclosed. An FM signal is received from an antenna and the received FM signal is provided to a receiver. The receiver takes the FM signal at the carrier frequency and outputs a baseband signal. This baseband signal is then processed by a DSP (301) which provides carrier frequency compensation and decoding to produce a data stream that a microprocessor provides to a host device. Frequency differences between the FM carrier frequency and the frequency used to demodulate the FM signal can shift the DC bias level of the baseband signal. The DSP compensates for such frequency difference by using a receive compensation value and applying it to each received signal sample. When transmitting, data to be transmitted is provided from the host device to the DSP via a microprocessor (103). The DSP provides encoding and carrier frequency compensation of the data to provide a baseband signal to a transmitter (303) that modulates the baseband signal to produce an FM signal at a desired carrier frequency. Frequency differences between the desired FM carrier frequency and the frequency used to modulate the baseband signal can produce errors in receiver systems. The DSP compensates for such a frequency difference by using a transmit compensation value and applying it to each encoded signal sample.
