Title: Polymeric strands with enhanced tensile strength, nonwoven webs including such strands, and methods for making same
Inventor: JAMESON LEE KIRBY
IPC: D04H3/16
Filed: 1997-04-28
Abstract: A melt-extrudable polymeric strand with enhanced tensile strength formed by extruding a melt-extrudable polymer while subjecting a portion of the polymer to ultrasonic energy. The melt-extrudable polymeric strand has a tenacity which is from about 1.5 to about 3 times the tenacity of an otherwise identical strand not made by applying ultrasonic energy to a portion of the melt-extrudable polymer while the melt-extrudable polymer is extruded. Desirably, the strand has a tenacity within a range from about 0.3 to about 0.9g/denier. In a method for making such a strand, a molten melt-extrudable polymer is extruded through a die assembly, ultrasonic energy is applied to a portion of the melt-extrudable polymer within the chamber and without applying ultrasonic energy to the die tip, while an extrusion exit orifice receives melt-extrudable polymer from an extrusion chamber, and the extruded polymer is attenuated to form a strand. The extrusion of the melt-extrudable polymer and the excitation of the means for applying ultrasonic energy are controlled such that the strand has the above-described tenacity. A nonwoven web comprises the strands with enhanced tensile strength.

Title: Low profile catheter valve
Inventor: ZADNO-AZIZI GHOLAM-REZA
IPC: A61F2/958
Filed: 1997-05-19
Abstract: Disclosed herein is a low profile catheter valve comprising a movable sealer portion positioned within the inflation lumen of a catheter. The sealer portion forms a fluid tight seal with the inflation lumen by firmly contacting the entire circumference of a section of the inflation lumen. The sealer portion may be positioned proximally of a side-access inflation port on the catheter, to establish an unrestricted fluid pathway between the inflation port and an inflatable balloon on the distal end of the catheter. As desired, the clinician may move the sealer portion to a position distal of the inflation port, thereby preventing any fluid from being introduced into or withdrawn from the balloon via the inflation port.

Abstract: A synchronization device (SYNC) for a synchronous digital message transmission system (SDH) serving the purpose of producing a synchronous output signal (STM-N) that consists of successive transport modules synchronized to a frame clock and of a digital input signal (PDH). The synchronization device (SYNC) exhibits the following: a receiver unit (SI) for receiving the input signal (PDH), packet assembly device (PAK) for packaging the input signal into subassemblies (VC-N) of the transport modules, buffer memory (BUF), a writer (WM) for writing data bits of the input signal (PDH) out of the subassemblies (VC-N) in the buffer memory (BUF) with a write clock (WCLK), a reader (RM) for reading data bits out of the buffer memory with a read clock (RCLK) in order to form the output signal, and a sending unit (SO) for sending synchronous output signals (STM-N). The effective bit rate of the subassemblies in comparison to the standardized value is either lowered or raised here by selecting the write clock (WCLK) lower than the read clock (RCLK).

Inventor: CATES GEORGE A
IPC: A61K39/275
Filed: 1997-07-11
Abstract: An immunization strategy to provide protection against disease caused by infection with a paramyxoviridae virus, specifically respiratory syncytial virus (RSV) and parainfluenza virus, is described. A priming intranasal administration of a recombinant virus expressing at least one RSV or PIV  protein or immunogenic sequence thereof first is made to the host followed by a booster administration of at least one purified RSV or PIV protein or immunogenic fragment thereof, which may be adjuvanted with alum. This immunization strategy provides a safe and effective means of controlling RSV  and PIV infections. The strategy leads to a stronger protective immune response than other strategies and to the induction of a more balanced Th-1/Th-2 type response than previously attained. Novel recombinant poxviruses are provided containing nucleic acid encoding a paramyxovirus protein or immunogenic fragment thereof in a non-essential region of the poxvirus genome, specifically NYVAC-F and ALVAC-F, which produce the F glycoprotein of RSV.

Patent CA-2287015-A1 (CA)
Inventor: SAWYER FRANCOIS
IPC: H04L12/26
Filed: 1994-11-01
Abstract: A method and system for locating control channels, particularly digital control channels are described. By grouping the channels which are candidates for carrying supervisory messages in blocks indicative of their relative likehood for being used as control channels, a mobile station can begin its search for a control channel with channels which are most likely to actually be control channels.      Placing location information on other channels allows the mobile station to be redirected to a control channel when it reads one of these other channels. Similarly, by placing information describing the location of a control channel in a message associated with handoff, a mobile station avoids the necessity of having to relocate a new control channel associated with the base station to which the mobile has been handed off.
