Abstract: The present invention relates to a fire arm silencer that utilizes internal reflection of shock waves and redirection of propulsive gasses to reduce the noise caused by the firing of a fire arm. The fire arm noise suppressor is comprised of a hollow body comprised of an end wall and a central opening with an inner tube extending partially within the body from the end wall of the hollow body. The inner tube has open ends and communicates with the central opening of the hollow body. Positioned between the inner tube and inner surface of the hollow body is a noise attenuating truss structure that is formed to break shock waves and redirect propellant gasses. The body further comprises a second end having an end wall that terminates into an outwardly extending hub. The hub has a centrally located bore that is formed to receive the end of a barrel of a firearm.

Abstract: A method and system for scheduling and managing manicure and/or pedicure appointments and payments includes: initiating a predefined electronic payment from individual consumers at predefined intervals of time, receiving appointment requests from individual consumers, routing each appointment request a manicure and/or pedicure provider, receiving messages indicating that a consumer has consumed an offered service at a manicure and/or pedicure provider, generating a human-readable spreadsheet file that lists a unique provider and a predefined payment amount, calculating a monetary transfer amount for each manicure and/or pedicure provider, and generating a NACHA-formatted file based on said spreadsheet file, wherein said NACHA-formatted file lists a unique provider, the monetary transfer amount, the provider bank account data and source bank account data.

Abstract: A rotary engine is provided that comprises a compression cylinder and combustion cylinder divided by a separation wall. Air or a fuel/air mixture is drawn into the compression cylinder, compressed, and then transferred to the combustion cylinder. The compressed air or air/fuel mixture is ignited in the combustion cylinder, creating an expansion of the combustion gases which drives the system. The compression and combustion cylinders have epicycloidal-shaped chambers that each house a single vane. The vanes pass through the crankshaft and adjust to remain in contact with the chamber walls as the crankshaft rotates. The compression ratio of the present invention can be maximized by adjusting the thicknesses of the compression and combustion cylinders as well as by offsetting the positions of the compression and combustion vanes with respect to one another.
