Abstract
Abstract An insert is disclosed to reduce noise for apparatus to prevent melted yarn stopped in high temperature yarn texturing jet. The insert is a cylinder at the outlet of the orifice emitting a cooling, diluting and diverting fluid, such as air, to prevent yarn when stopped in the steam texturing jet from being melted. The insert comprises a cylinder having a series from about 5 to 10 cylindrical openings evenly distributed across the orifice and with axes parallel to the orifice axis. The cylindrical openings preferably have a length to diameter ratio of from about 5 to about 10.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
171 words
In an apparatus to prevent melted yarn when stopped in a high temperature yarn texturing jet device, having a high temperature fluid flowing across a yarn entry, comprising a sensor to detect yarn stoppage which actuates a valve in a high pressure conduit communicating with an orifice opposite said yarn entry in said high temperature texturing jet device so that upon actuation of said valve by said sensor, a blast of high pressure fluid diverts and dilutes any undiverted said high temperature fluid flowing across said yarn entry in said texturing jet device out of said texturing jet device through said yarn entry, the improvement comprising a noise reduction insert at said orifice, said insert comprising a cylinder having a series of from about 5 to 10 cylindrical openings evenly distributed across said orifice and with axes parallel to said orifice axis; said cylindrical openings having a length to diameter ratio of from about 5 to 10, and said insert having a tapered inlet adjacent the inlet of said cylindrical openings.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
21 words
The insert of claim 1 wherein said length to diameter ratio is 6.25, and said insert has seven said cylindrical openings.
