Abstract: A menthol-containing solids composition comprising or consisting of: (a) a solid menthol component consisting of bodies having a content of 95 wt. % or more of menthol, based on the total weight of the bodies, and (b) a solid anticaking agent, comprising or consisting of particles having a particle size of not more than 100 ?m, wherein particles of the anticaking agent adhere to the surface of the bodies of the menthol component, wherein the solid anticaking agent is chosen from the group consisting of calcium phosphate, magnesium phosphate, magnesium hydroxycarbonate, magnesium oxide, mixtures of magnesium oxide and silicon dioxide, mannitol, calcium silicate, magnesium silicate, talc, polydimethylsiloxane, Al, Ca, K, Na, Mg or NH4+ salts of edible fatty acids, and mixtures thereof, and wherein the content of the anticaking agent is not more than 8 wt. % and the content of the menthol component is at least 91 wt. %, in each case based on the total weight of the solids composition.

Abstract: Methods and apparatus are provided for active motion damping of a spacecraft whose attitude control system (SACS) has experienced a partial failure. In a preferred embodiment, the apparatus comprises, an attitude control processor (ACP), a motion damping controller (MDC) coupled to the ACP, a control moment gyro (CMG) comprising a gimbal loop controller (GLC) coupled to the MDC and a gimbal motor with input coupled to the GLC and gyroscopic torque output coupled to the satellite. Normally, a gimbal rate command (GRC) from the ACP passes to the GLC for execution to rotate the CMG gimbal and the coupled satellite. If the ACP output becomes invalid, the MDC assumes control and can modify CMG operation in several ways to safely decelerate a moving satellite without hazardous mechanical stress. Following such active motion damping, the CMG remains quiescent until a RESET is received whereby further valid GRCs are then executable.

Abstract: A valve is provided for use on a control moment gyroscope (CMG) having a housing separating an internal environment from an external environment. The valve includes a valve housing, a valve element, and bellows. The valve housing is configured to couple to the CMG housing and includes an inner surface defining a cavity, an outer surface, and an opening extending therebetween. The valve element is disposed within the valve housing cavity and is movable between a closed position, in which fluid is prevented from flowing through the valve housing opening, and an open position, in which fluid may flow through the valve housing opening. The bellows is disposed within the valve housing and coupled to the valve element and has an internal chamber. The bellows selectively moves the valve element closed and open in response to a differential pressure between the bellows internal chamber and the valve housing cavity.
