Abstract
Abstract Apparatus and method are disclosed to prevent melted yarn when stopped in a high temperature texturing jet device having high temperature fluid (such as steam) flowing across a yarn entry slot. The invention comprises sensing yarn stoppage with a sensor and actuating a valve in a high pressure conduit communicating with an orifice opposite the yarn entry in the texturing jet device and diverting and diluting the high temperature fluid (such as steam) flowing across the yarn entry slot out of the texturing jet device through the yarn entry slot with high pressure fluid (such as air) so that elements in the texturing jet device downstream from the yarn entry are no longer heated by high temperature fluid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
A method to prevent melted yarn when stopped in high temperature yarn texturing jet device having a high temperature fluid flowing across the yarn entry comprising sensing yarn stoppage with a sensor, and actuating a valve in a high pressure fluid conduit communicating with an orifice opposite said yarn entry in said texturing jet device, and diverting and diluting any undiverted said high temperature fluid flowing across said yarn entry out of said texturing jet device through said yarn entry with said high pressure fluid so that elements in said texturing jet device downstream from said yarn entry are no longer heated by said high temperature fluid.
Claim 2
Independent Claim
107 words
A method to prevent melted yarn when stopped in high temperature yarn texturing jet device having a high temperature fluid flowing across the yarn entry comprising sensing yarn stoppage with a sensor, and actuating a valve in a high pressure fluid conduit communicating with an orifice opposite said yarn entry in said texturing jet device, and diverting and diluting any undiverted said high temperature fluid flowing across said yarn entry out of said texturing jet device through said yarn entry with said high pressure fluid so that elements in said texturing jet device downstream from said yarn entry are no longer heated by said high temperature fluid.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein said high pressure fluid is air and said high temperature fluid is steam.
Claim 4
Independent Claim
104 words
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 fluid conduit communicating with an orifice drilled 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.
Claim 5
Independent Claim
104 words
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 fluid conduit communicating with an orifice drilled 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.
Claim 6
Dependent Claim
17 words
The apparatus of claim 3 wherein said sensor is a feeler arm situated to contact said yarn.
