Abstract: The connector assembly includes a fitting with a first mounting portion having two opposing surfaces and mounting hole(s) extending between the two surfaces for connecting with a first member. A second mounting portion extends angled with respect to the first mounting portion and has two opposing surfaces and mounting hole(s) extending between the two for connecting with a second member. A joint portion integrally connects the first and second mounting portions. One or more washers each have opposing upper and lower surfaces and at least one hole extending between the two surfaces, each receiving a fastener for attaching the second mounting portion to the second member. The washer lower surface is disposed on the second mounting portion inner surface such that the washer opening is centered about the at least one mounting hole axis. Each washer is joined to the second mounting portion to form an integral assembly.

Abstract: A signaling device for signaling heating in a mechanical system susceptible to undergo contact heating during operation. The signaling device includes a body containing a thermally triggered charge generating combustion gas, ignition of the charge able to be triggered under the effect of a predetermined heat contribution, from a heating area of the body toward the charge, or under the action of an ignition command, a reservoir containing a fluid, and delivery means delivering pressurized fluid outside the reservoir through the action, directly or through an intermediate member moving in the reservoir, of the combustion gases. The signaling device also comprises at least one visual signaling element for visually signaling combustion of the charge, the visual signaling element being visible at an outer peripheral area of the signaling device after combustion of the charge. The invention also relates to a mechanical system equipped with at least one such signaling device.
