Abstract: A clock has an ornamental pendulum which serves an aesthetic function but does not control the clock mechanism. The pendulum is mounted for free swinging movement on an oscillating shaft in such a manner that, when the pendulum swings in synchronism with the oscillating shaft, the pendulum will be driven by the shaft, but, when the pendulum swings out of synchronism with the oscillating shaft, the pendulum will eventually stop swinging. Adjusting structure is provided to impart to the pendulum a natural period of swing which is in synchronism with the oscillating shaft.

Abstract: A molding press for forming articles from thermoplastic sheet materials comprises a generally hollow, fluid-tight housing, the lower surface of which comprises a flexible gas-tight diaphragm. The housing is movably positioned above a flat base, on which there is placed a mold covered with a softened sheet of thermoplastic material. During a molding cycle, the housing is lowered and interlocked with the base bringing the diaphragm adjacent the mold, and a fluid under pressure is introduced into the housing, causing the diaphragm to exert a uniform force on the thermoplastic sheet and forcing it to assume the contours of the mold. The base is equipped with mechanical and electrical interlock means which cooperate with the housing to insure that the fluid pressure cannot be applied until the housing and the base are safely interlocked and that the housing cannot be separated from the base while fluid pressure is supplied to the housing.

Abstract: The present invention relates to a method and device for controlling a hydraulic disc brake, particularly for heavy-transport aircraft, wherein the functioning of the brake is servo-controlled so that the braking torque which it exerts follows the variations of a predetermined reference torque.
