TL;DR: In this paper, a closed cylindrical valve body with one end connected to a system to be evacuated, and a tube extending from the side wall to a vacuum pumping system is described.
Abstract: A vacuum safety valve comprises a closed cylindrical valve body having one end connected to a system to be evacuated, and a tube extending from the side wall to a vacuum pumping system. The other end of the valve body includes a port connected to ambient air through a solenoid operated valve which is normally open when de-energized. An extendable bellows is secured about the port on the inside of the valve body, and the distal end of the bellows is sealed by a plate having a small bleed hole in the edge thereof. Should the pumping system fail, the solenoid valve is deactuated to open the bellows interior to ambient air. The air pressure expands the bellows and drives the plate against the interior port to seal off the system side of the valve before the vacuum therein is destroyed.

23 Jan 1990TL;DR: In this paper, a vibration isolating support apparatus comprises an air spring in the form of the bellows and a multiple laminated rubber assembly, which are vertically stacked and integrally connected each other.
Abstract: A vibration isolating support apparatus comprises an air spring in the form of the bellows and a multiple laminated rubber assembly. The air spring and the multiple laminated rubber assembly are vertically stacked and integrally connected each other. The multiple laminated rubber assembly is composed of a plurality of stacks of a plurality of laminated rubbers and a plurality of stabilizing plates which are inserted between and connected to the upper and lower ends of the adjacent laminated rubbers in the stacks.

TL;DR: In this paper, an improved fishing lure is described, which is formed by a simulated frog-like body, the body including an anchoring point for a fishing line at the forward end thereof, and a novel tail structure located at the opposed end of the body.
Abstract: There is disclosed an improved fishing lure which is formed by a simulated frog-like body, the body including an anchoring point for a fishing line at the forward end thereof, and a novel tail structure located at the opposed end of the body, the tail structure consissting of a pliable and flexible coiled structured formed of a material having a memory thereby permitting the coiled structure to achieve a bellows action during the lure manipulation causing a circular vibrational motion of the water as the lure travels through the water for the purpose of attracting fish The tail structure is formed of a material which normally biasingly urges the tail into a tightened bellows configuration when not in use, and uncoils in a bellows fashion and creates a circular vibratory motion during use, the tail material having a self memory thereby to biasingly urge the tail back into its tightened bellows configuration
