and then file more as necessary. The idea is to effectively “sneak up” on the gap. Once the gap is set, you should gently deburr the end gap with another small, fine-tooth hand file. If the end gaps are excessive, you’ll have to purchase a new ring or ring set, so...

The essential parts of a pistonphone are a coupler, into which the microphone cartridge is inserted and sealed, usually with an O-ring, and a vibrating piston of known displacement. The piston may be driven by a cam having a sinusoidal contour, generating a pure tone, or by a crankshaft,...
The stopping ring has four steps on it, which progressively reduce the clearance for oil venting as the piston slows down. In the final stage, the piston is held by the force of the driving air, which remains greater than the force of the compressed mixture in the reaction chamber. Based...
Manring found that a constant area slot design had the advantage of minimizing the required discharge area of the slot, the linearly varying slot design had the advantage of utilizing the shortest slot length, and the quadratic slot design had no particular advantages over the other two. Ivanty...
ring area of the piston. Sealing of the gaps in such rings with plastics material has been disclosed in the Knocke U.S. Pat. No. 3,053,545, but such gap sealed rings do not provide a plastic sealing face riding on the cylinder wall and are not intended for use as compression rings....
as the rings in the piston have a gap spacing within them allowing for an amount of travel in the ring that is not available in a ringless piston motor. The ring typically expands first in the mechanical sense, providing a tight fit around the piston at start up. The ring can then adj...
Suitable cyclic olefin monomers are monocyclic compounds having from 5 to about 10 carbons in the ring. The cyclic olefins can be selected from the group consisting of substituted and unsubstituted cyclopentene, cyclopentadiene, cyclohexene, cyclohexadiene, cycloheptene, cycloheptadiene, cyclooctene, cycloo...
Thus, the piston seal ring moves along with the piston assembly but the housing seal ring remains stationary with the housing. The air or fluid passage 52 is configured for discharging air or fluid between the O-rings 24, 24. The increase in pressure between the O-rings causes the piston ...
