Abstract:
A pressure measuring device comprising a U-shaped clamp which is easily and rapidly attached to or removed from a pressurized enclosure to measure pressure thereon by measuring deformation of the enclosure without breaking the surface of the enclosure. Deformation of the enclosure is measured by detecting changes in strain in the arms of the clamp by strain gage means. The device is insensitive to the effects of acceleration thereon.
Abstract:
An anti-sway apparatus for use in a tow vehicle-trailer braking system to provide the wheel brakes of the trailer with an actuation signal sufficient to initiate a lesser acceleration in the trailer than in the tow vehicle to develop a uniform acceleration in the tow vehicle-trailer combination.
