Abstract: The disclosed and claimed compressed gas system provides for the use of a rotary valve assembly in association with a cupper. A compressed gas system that utilizes a rotary valve assembly uses less gas than a constant flow compressed gas system and is quieter than a compressed gas system that uses valves. The rotary valve is a disk-like body having an opening therethrough. The rotary valve body is disposed within a housing assembly wherein gas may only flow through the housing when the rotary valve body is properly aligned with a space on one side of the rotary valve body.

Abstract: The invention relates to the field of physics—namely, to control systems and the pressure control of liquids and gases, in particular—to stabilizing devices operating at overloads, including hydraulic shocks. Technical result from use of the claimed invention is simplicity of the manufacturing process and assembly, easiness of operation and efficiency of quenching pulses. A method consists of the fact that at the section of said pipeline installed at least one pressure pulse stabilizer in the direction of movement of transferred medium from supplier to consumer. Pulse flow is directed as a first portion into the stabilizer, and after its first portion a second portion of the flow is directed, which after a delay is sent into additional input of the stabilizer. The potential sources of pressure pulses are preliminary revealed on the protected section of the pipeline.

Abstract: A ball valve with offset straight through flow is provided. The ball valve has a housing having an inlet and an outlet and an internal cavity. A non-spherical ball valve member is positioned within the internal cavity. The valve member is mechanically coupled to a valve stem extending from the internal cavity to an exterior of the housing such that rotation of the valve stem results in a like rotation of the valve member. The ball valve has a fully closed position wherein fluid flow therethrough is prevented. The ball valve member also has a fully opened position where fluid flow therethrough is allowed. The ball valve can transition from the fully closed position to the frilly opened position and vice versa with a rotation of the valve member of less than or equal to about forty-five degrees.

Abstract: In a multi-roll table ring-rolling mill and method, a mandrel roll can be switched from a rolling state into a free-running state, when a predetermined ring diameter is reached, even if the roll gap minimum has not yet been reached, in order to improve the size accuracy of the rolled rings. A mandrel roll table rotating about a mandrel table axle is used, along with at least one main roll rotating about a main roll axle and first and second mandrel rolls that are mounted in the mandrel roll table, and a relief device to relieve at least the first mandrel roll of rolling forces. The main roll axle and the mandrel roll table axle are mounted in unchangeable manner and eccentric to one another, at least during the rolling process. The relief device acts independent of the main roll axle and the mandrel roll table axle are eccentric to one another.

Abstract: A system and method of increasing a dwell time in a foil stamping press is provided. The dwell time is readily adjusted on the fly by the user for a given operating rate. A timer is used to adjust the press to stop on top dead center with changes in images per hour. An air clutch and an original equipment air brake are used in tandem to provide the desired dwell time. A pair of timers governs a pneumatic switch for control of the air clutch and the air brake. The present system and method increase die image area capacity as compared to conventional foil stamping presses. The increased dwell time press yields a flawless foil stamped image for an impression pressure less than that required in a conventional machine for a given die, mounted at a given height upon a stationary platen, and at a given temperature.
