IPC: C07K/
Filed: 1993-01-08
Abstract: The cloning, sequencing and expression of a novel receptor tyrosine kinase, termed tie, is described. The tie precursor comprises 1138 amino acid residues, about 1117 residues of which comprise the mature tie. The tie extracellular domain contains distinct stretches of amino acid sequence having features of the imunoglobulin, epidermal growth factor and fibronectin type III repeat protein families. Alternative splicing creates variants of tie which lack one of the epidermal growth factor homology domains. A  specific tyrosine phosphorylated 117 kD glycoprotein is detected by specific tie-antisera from cultured cells expressing the tie gene.  The tie mRNA is expressed in cultured endothelial cells as well as in a few tumor cell lines. In situ hybridization of human fetal and mouse embryonic tissues shows specific expression in endothelial cells of blood vessels. The tie DNAs and polypeptides of the invention may be useful in the diagnosis and treatment of certain diseases involving endothelial cells and their tie receptor such as neoplastic diseases involving tumor angiogenesis, wound healing, thromboembolic diseases, atherosclerosis and inflammatory diseases.
Patent CA-2129945-A1 (CA)
Title: Infra-Red forced Air Dryer and Extractor
Inventor: SECOR HOWARD C
IPC: F26B13/10
Filed: 1994-08-11
Abstract: An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets. An extractor exhausts the moisture-laden air from an exposure zone while short wave infra-red radiation heats the ink and/or protective coating: The effective exposure to high velocity, hot air is increased by the air jets which produce a balanced pressure air blanket along the sheet travel path. The moist air layer is displaced from the printed and/or coated sheet and is extracted from the press as the sheet moves through the exposure zone.

Patent CA-2137535-A1 (CA)
Inventor: RECHT THOMAS S
IPC: H04M1/725
Filed: 1994-12-07
Abstract: A method for designating messages allows individual messages to be designated as "read" if (i) the message has been played for a predetermined amount of time (150) or (ii) the replay of the message is completed (154). After a playback session, messages designated as "read" can be designated as "old" (102). Because of the queuing capability of the digital answering machine (142), stored messages can be replayed in any order, or a portion of a message can be conveniently replayed to determine whether the message should be replayed in full. As a result, new messages (i.e., messages which have not been designated as "read") can be located anywhere in the sequence of recorded messages. Such a function of the present invention allows a user to preview messages to selectively listen to messages, while maintaining a designation as "new" for any message in the sequence which has not been replayed in full or at least for a predetermined period of time. A user has the option of playing back all messages (92), or only those messages designated as "new" (98).
