Title: Syringe disposal system
Inventor: BEINECKE GREGORY L
IPC: B02C18/22
Filed: 1995-10-05
Abstract: A disposal system for cutting a needle/syringe (22) into small pieces. One or more motor driven rotating cutting blades (6) are located inside of a housing for cutting the needle/syringe (2) into small pieces. The pieces are deposited in a disposal tray (10) filled with a disinfecting solution, with the parts of the needle/syringe (2) automatically separating for recycling due to the specific gravity of the pieces. A pump (16) is provided for pumping the disinfecting solution, preferably a mixture of chlorine bleach and water, to the needle/syringe inlet (8) and cutting area.

Abstract: Apparatus for recompleting an oil and/or gas well includes a primary tubing hanger, and primary well tubing hung from the hanger within the well, and a communication/hanger nipple, located below the primary tubing hanger, which is suitable for receiving and locating a coil tubing hanger.  The communication/hanger nipple is run into the well as part of the initial completion in any situation where there is a potential requirement for a coil tubing completion later in the life of the well but plays no part in the normal primary production operation of the well.  However, should production fail for any reason, requiring coil tubing recompletion, the communication/hanger nipple is available to support the coil tubing and provide communication to the subsurface equipment without the necessity of modifying the primary tubing hanger.

Abstract: ABSTRACT OF THE DISCLOSURE          An edge-lighted panel, useful as an illuminating panel or as an illuminated sign has a shallow peripheral frame which contains the light source. The frame supports an external, illuminated face panel on one or both its sides. A light diffusion panel located within the frame is interposed between the light source and the illuminated face panel, being inclined at a slight angle from the face panel, to refract light onto the inner surface of the face panel. Light emitting diodes (LED's) may be used as the light source. In the case of an illumination panel, a reflective interior panel may be used in conjunction with the diffusion panel to direct the light to the illuminated face.          The diffusion panel may comprise commercial diffusion sheeting normally used to enclose fluorescent lighting.  The panel frame preferably comprises extruded plastic of modified U-section.          Portions of the sign face may be masked, in known fashion, to provide an illuminated sign or symbol, such as an exit sign or a directional arrow.  Dual electrical connections for A.C. mains and batteries such as 12-volt or multiples can be provided.

Title: Antiviral compounds that inhibit interaction of host cell proteins and viral proteins required for replication
Inventor: PALESE PETER
IPC: G01N33/53
Filed: 1995-10-06
Abstract: The present invention relates to the identification of host cell proteins that interact with viral proteins required for virus replication, and high throughput assays to identify compounds that interfere with the specific interaction between the viral and host cell protein. Interfering compounds that inhibit viral replication can be used therapeutically to treat viral infection. The invention is based, in part, on the Applicants' discovery of novel interactions between proteins of the influenza virus and human host cell proteins. One of these host cell proteins, referred to herein as NPI-1, interacts with influenza virus protein NP, and may be an accessory protein required for replication of influenza virus. Another of these host cell proteins, referred to herein as NS1I-1, interacts with influenza virus protein NS1. Compounds that interfere with the binding of the host cell and viral proteins, and inhibit viral replication can be useful for treating viral infection in vivo.
