Patent number: 12193174Abstract: A thermal sleeve for protecting an electronic member connected to a wiring harness against exposure to heat is provided. The thermal sleeve has a tubular member including a circumferentially continuous wall with an inner surface bounding an inner cavity extending along a central axis between open opposite ends and a reflective outer surface. The thermal sleeve includes a positioning member constructed of a separate piece of material from the tubular member. The positioning member has a circumferentially continuous, tubular portion and at least one resilient flange extending radially inwardly from the tubular portion for abutment with the wiring harness. The tubular portion has a plurality of tangs extending radially therefrom. The tangs are fixedly disposed in the wall of the tubular member to inhibit relative rotational and/or axial movement between the tubular member and the positioning device.Type: GrantFiled: August 3, 2016Date of Patent: January 7, 2025Assignee: FEDERAL-MOGUL POWERTRAIN, LLCInventor: Alexa A.

Patent number: 11834760Abstract: An end fray resistant textile sleeve includes an elongate wall having warp yarns extending generally parallel to a longitudinal central axis of the sleeve and fill yarns extending circumferentially about the sleeve. The warp yarns include at least two different types of yarns, with one of the types of warp yarns including activateable yarns and another of the types of yarns including non-activateable yarns. The activateable yarns can be provided as being activateable by at least one of heat, fluid and/or pressure, such that upon being activated, the yarns are caused to bond with the adjacent non-activateable warp yarns, as well as with the weft yarns with which they make contact. As such, the activateable yarns, upon being activated, become fixed with abutting warp yarns and weft yarns, thereby inhibiting end fray from resulting during a subsequent cold-cutting operation as well as in use.Type: GrantFiled: February 3, 2022Date of Patent: December 5, 2023Assignee: Federal-Mogul Powertrain LLCInventors: Alexa A.
