摘要： The method of providing a clamping connection comprising providing one or more clamping hubs, providing two or more clamping segments to engage the clamping hubs, constraining the clamping segments to move approximately radially with respect to the clamp hubs, providing a tension band around the clamping segments which slides circumferentially relative to the clamping segments, and adjusting the ratio of the contact area of the tension band to the clamping hubs and the area of the clamping hubs to compensate for the difference in loading on the clamping hub due to sliding friction between the tension band and the clamping hubs.

摘要： In a blowout preventer body having a central bore a method of reducing the size and weight of the blowout preventer body while maintaining an acceptable stress level at working pressure comprising machining a portion of the blowout preventer body to proximate the final dimensions, pressuring the blowout preventer body to a higher pressure than the working pressure of the blowout preventer body to yield high stress areas of the blowout preventer body, and relieving the higher pressure from the blowout preventer body such that when the blowout preventer body returns to the non-pressured state the high stress areas will retain compressive stresses and when the blowout preventer body is then pressurized to the working pressure of the blowout preventer body the stresses will be at an acceptable stress level.

摘要： A method of providing a virus and other pathogen protection for a person comprising providing a mask in which incoming air must pass across multiple surfaces constructed of multiple layers of a sticky material with a circuitous path to capture any airborne viruses and other pathogens irrespective of their size with the outgoing air taking a different path than the incoming air to prevent breathing moisture from interfering with the sticky capture and including a mouthpiece to prevent mask leakages.
