Patent CA-2151580-C (CA)
Inventor: LOTSPEICH JOSEPH A
IPC: B65G59/10
Filed: 1995-06-12
Granted: 1999-04-27
Abstract: The present invention provides an apparatus that dispenses a lowermost cup from a stack of nested cups. The cups are disposed within an opening formed through an annular housing, and a group of cam assemblies project inward from the housing to support and selectively dispense the cups.  Alignment holes are formed through the housing and the cam assemblies to facilitate proper alignment of the cam assemblies relative to one another during assembly of the dispenser.  The cam assemblies move inward and outward relative to the opening to accommodate cups of different under-rim diameters within a given range.  In particular, the cam assemblies move in an arc and pivot relative to the housing and thereby remain satisfactorily aligned relative to the center of the opening over a wider range of under-rim cup diameters.

Granted: 2006-12-05
Abstract: A forehearth (20) for cooling glass from a melting furnace as it flows to a feeder bowl (28) from which it is discharged to a forming machine. The forehearth is in the form of an elongate, horizontally extending insulated trough (26) with a roof formed by a longitudinally extending series of roof block elements (30), each of which is of one-piece construction and extends completely across the width of the insulated trough. The downwardly facing surface of each roof block element is contoured to incorporate concave portions (30a, 30b) near the edges of the forehearth, a concave portion (30c) above the center of the forehearth and convex portions (30d, 30e) separating the center concave portion from the side concave portions to substantially impede heat transfer between the side concave portions and the center concave portion. Burners (32) are positioned along the opposed sides of the forehearth to fire transversely into the spaces underlying the side concave portions of the roof blocks, and cooling air passages (40) extend through the roof blocks to discharge cooling air transversely of the forehearth into the space underlying the center concave portion in direct contact with the glass in the forehearth. A plurality of exhaust openings (34, 42) for products of combustion from the burners and cooling air, respectively are positioned along the length of the forehearth to provide for longitudinal flow of products of combustion and cooling air at rates which are variable along the length of the forehearth.

Title: Combined antenna apparatus and method for receiving and transmitting radio frequency signals
Inventor: FILIMON CRISTIAN C
IPC: H04B1/18
Filed: 1996-06-06
Granted: 1999-08-24
Abstract: An antenna system and method for use in a portable unit of a wireless telephone headset, wireless telephone headset adapter, or other telecommunication device combines a capacitive coupling antenna with an electric field sensitive antenna. The electric field sensitive antenna, such as a monopole antenna, receives and transmits RF signals when the portable unit is located remote from the user. A patch antenna receives and transmits RF signals when the portable unit is located proximate to, for example is worn by, the user. The patch antenna is a conductive surface for capacitively coupling to a user's body which acts as a radiating and receiving medium. Both the patch antenna and monopole antenna are coupled to an antenna port by matching circuits to tune each antenna for desired RF characteristics. When worn by the user, the RF effects of the monopole antenna are negligible and the patch antenna operates as the primary antenna. When located remotely from the user, the patch antenna will not be capacitively coupled to a body and the RF effects will be negligible as compared with the RF effects of the monopole antenna. The portable unit of a wireless headset receives and transmits signals when the portable unit is located either proximate to the user or remote from the user.

Title: Compounds for the treatment of disorders related to vasculogenesis and/or angiogenesis
Inventor: GAZIT AVIV
IPC: C12P21/08
Filed: 1995-02-09
Granted: 2009-04-21
Abstract: The present invention relates to organic molecules capable of modulating tyrosine kinase signal transduction and particularly KDR/FLK-1 receptor signal transduction in order to regulate and/or modulate vasculogenesis and angiogenesis. The invention is based, in part, on the demonstration that KDR/FLK-1 tyrosine kinase receptor expression is associated with endothelial cells and the identification of vascular endothelial growth factor (VEGF) as the high affinity ligand of FLK-1. These results indicate a major role for KDRJFLK-1 in the signaling system during vasculogenesis and angiogenesis.  Engineering of host cells that express FLK-1 and the uses of expressed FLK-1 to evaluate and screen for drugs and analogs of VEGF involved in FLK-1 modulation by either agonist or antagonist activities is also described. The invention also relates to the use of the disclosed compounds in the treatment of disorders, including cancer, diabetes, hemangioma and Kaposi's sarcoma, which are related to vascylogenesis and angiogenesis.
