Abstract: A pressure balance bearing providing a hydrostatic bearing film, which is connected to maintain a load or device in a constant position in relation to a reference or support surface. Several support bearings are plumbed together so that there may be cross flow between the bearings. An external control valve is mounted on the member and senses the relative position of the object. The valve in turn adjusts the flow of oil into the bearings as a function of changes of relative position of the object and reference or support surface. As shown, a large mass is supported on the pressure balance bearings and is capable of bilateral movement. The mass is supported on a plurality of bearings using three control valves arranged in a tripod configuration.

Each mounting includes an attachment plate to be secured to the vehicle and having flanges forming a mouth for lateral reception of the respective beam end and an apertured box-shaped casing provided on the respective beam end and interfittable with the flanges so as to close the mouth and constrain the beam from movement laterally and lengthwise of the mountings.

Abstract: Apparatus and method for assembling a flexible damped bearing within a rotary machine for properly locating the various bearing components in reference to the machine shaft, whereby the bearing will respond to the shaft in a predetermined manner.

Abstract: The invention relates to an emergency braking system for a tracked vehicle, uch as a military tank. Loss or separation of one or both tracks from the vehicle energizes an electrical sensor which automatically triggers an emergency brake control system operating on the road wheels. The track loss triggers a "driver override" system that inhibits manual steering, manual shift change, and manual sprocket brake operation. The emergency system takes over control of the vehicle to preclude the driver from making unsafe inputs to the system.
