Title: Catheter insertion device with retractable needle
Inventor: HALSETH THOR R
IPC: A61M25/00
Filed: 1998-11-12
Abstract: A catheter insertion device (10) is provided for inserting an over-the-needle catheter (50). The device includes an insertion needle (20) that is retractable into the housing (30) of the device after use to prevent exposure to the contaminated needle. A needle retainer (40) releasably retains the needle in an extended position against the rearward bias of the biasing element (60).

Abstract: A Network Call Trace (NCT) method and system enables a call path route to be traced in a telecommunications network. A Type of Digit (TOD) in the Generic Digits Parameter (GDP) for an Integrated Services Digital Network (ISDN) User Part (ISUP) command can be utilized to realize the NCT. A listing of Switch IDs (SIDs) from the originating subscriber's switch to the terminating subscriber's switch is provided so that routing inefficiencies can be discovered. In one embodiment, an Initial Address Message (IAM) is transmitted with a TOD Network Call Trace in the GDP. The NCT includes the SID of the originating switch. Any intermediate switches between the originating switch and the terminating switch likewise append their own SID onto the NCT list of SIDs. Finally, the terminating switch also adds its SID onto the end of the NCT list. This NCT list may then be transmitted and displayed for analysis.  For example, it may be transmitted in a backward message such as address complete message (ACM), answer message (ANM), call progress (CPG), or release (REL) back to the originating switch via the network. Alternatively, the NCT  list may be sent to a Network Management Center.

Title: Paper machine, paper machine belt for and method of manufacturing textured soft paper
Inventor: OSTENDORF WARD W
IPC: D21H27/00
Filed: 1998-12-16
Abstract: A paper machine for manufacturing textured soft paper comprises a press section with a press nip, through which an impermeable belt and a felt run with the fibrous web between them, a drying cylinder and a transfer roll forming a nip for transfer of the web to the drying cylinder. Smooth impermeable belts ride less of the web over longer distances, and do not facilitate web transfer to a smooth roll. The impermeable belt is a texturing belt with a web-contacting layer having depressions and surface portions forming a relief pattern in the web, the texturing belt running from the press to the drying cylinder carrying the textured web to the transfer nip.  The felt runs away from the texturing belt before a water film formed in the press nip breaks up. Adhesive is applied on the drying cylinder before the transferring.
