Title: Adenoviruses having modified fiber proteins
Inventor: MCCLELLAND ALAN
IPC: C12N15/87
Filed: 1994-08-11
Abstract: An adenovirus wherein the adenovirus fiber protein includes a ligand which is specific for a receptor located on a desired cell type. The adenovirus may have at least a portion of the adenovirus fiber protein removed and replaced with a ligand which is specific for a receptor located on a desired cell type, or the adenovirus may include a fusion protein of the adenovirus fiber protein and the ligand.

Patent CA-2170263-A1 (CA)
Title: Electrophoretic display having reduced writing time
Inventor: DISANTO FRANK J
IPC: G02F1/167
Filed: 1994-08-15
Abstract: An electrophoretic display (10) is provided which enables an image to be displayed by selectively energizing intersecting grid (16) and cathode (14) lines each indicative of a pixel and varying the bias between the lines to cause suspended pigment particles to migrate to an anode (20) and away from the energized pixels. Selected intersections of grid (16) and cathode (14) lines indicative of pixels are energized with a set of voltages during a fixed time interval, thereby causing an image to be displayed thereon. The time interval selected is less than the time required to completely remove the pigment particles from the pixels and the image is sequentially enhanced by rewriting at least some of the pixels with the set of voltages at least once. This permits a readable image to be produced much more rapidly and also provides incrementally darker pixels in the image as additional pigment particles are moved from selected intersections during subsequent energizing intervals.

Title: A process for separating lipophilic compounds
Inventor: FEX TOMAS
IPC: C11C1/00
Filed: 1994-10-19
Abstract: This invention relates to novel urea fractionation process for purification of e.g. fatty acids and derivatives thereof. The process is characterised in that the urea complexation takes place under heterogenous conditions using a solvent or solvent mixture wherein the fatty acids (or derivatives) are only slighty soluble. thus forming a two-phase system. This allows for continued regeneration of urea and simple procedures for product isolation.

Patent CA-2182749-A1 (CA)
Inventor: VONESCH ANTHONY RICHARD
IPC: A01D80/00
Filed: 1996-08-06
Abstract: When hay in the field is cut, it is left to dry before being baled. The hay stores better if its moisture content is low.   To help the drying process a rake is often used to turn the cut hay. This may beraked several times if the weather prevents fast drying of the hay.   In this invention, when the rake is attached to a tractor by means of a single point hitch, a lifting mechanism has been designed to lift the rake, above the cut hay.   The invention enables the farmer to have complete control of where and when he wants to lower or raise the mechanism. He can also use it to select the height he wants to rake. It also helps to protect the raking mechanism when being towed on a road or bumpy surface.

Patent CA-2187035-A1 (CA)
Inventor: FORD WARWICK STANLEY
IPC: H04L9/32
Filed: 1995-02-22
Abstract: Novel cryptographic key distribution techniques to be used in large computer networks are disclosed.  The techniques require trusted key release agent systems in each security domain. The encryptor (10) of a data message nominates to set of authorized decryptors (30), using a set of access control attributes recognized by a key release agent (32) in a target security domain. Data enabling the message decryption key and the access control attributes to be recovered are sent to the decryptor in an access controlled decryption block, which is encrypted under a separate key. The access controlled decryption block can only be decrypted by a key release agent (32) in the correct security domain. The key release agent recovers the decryption key and supplies it to an authorized decryptor (30), which allows the decryptor to recover the original data message.
