Abstract: Auto-deicing system with a valve having a butterfly plate (5).The spindle (8) of the valve (4) is controlled by a system terminated by a pin (11) coaxial to the spindle (8) and which, like the latter, has slots (13). When the pin (8) is iced up, the control system initiates a movement of the pin (11) so that the slots (12, 13) come into extension with one another, which allows a circulation of the hot gas on one side of the butterfly plate (5) through the spindle (8), which is thus reheated. The opening movement resumes when the ice has melted.The invention is applicable to cold starting systems on aircraft engines.(FIG.

Abstract: A bearing assembly is disclosed for supporting the downstream end of a shaft for a position indicating system for a turbofan thrust reverser. The bearing assembly has a pair of support arms supporting a bushing which is attached to the downstream end of the shaft. The arms are oriented in a plane substantially transverse to the longitudinal axis of the shaft and are clamped to a mounting bracket by spring biased mounting plates. Belleville springs are utilized to provide the biasing force and may be adjusted to compensate for wear of the system.
