Cylinder pressure is maintained substantially at a setpoint, the setpoint being adjustable in response to varying terrain. The setpoint is set to a first value in falling terrain and a second value in rising terrain. At the top of a hill, the setpoint is reduced below the first value until ground contact is regained, and the pressure is recharged above the second value.

Abstract: To piece an open-end spinning device, the yarn end is introduced into the spinning rotor while the spinning rotor is stopped. An auxiliary suction air stream prevailing at the opener roller housing takes effect and sucks the yarn into the fiber feeding channel where it is held. The spinning rotor which was stopped until then is then again driven. Following this, the negative spinning pressure is switched on while the auxiliary suction air stream is simultaneously switched off. This causes the yarn end to be taken out of the fiber feeding channel and to be fed to the fiber collection surface of the spinning rotor where it is combined with the fibers which are again conveyed to the fiber collection surface. The yarn is then withdrawn in the form of a continuous yarn through the yarn draw-off pipe and out of the spinning rotor.

Abstract: An integrated adsorption/cryogenic distillation process is set forth for the separation of an air feed. The air feed is passed through a vacuum swing adsorption (VSA) unit to remove impurities comprising water and carbon dioxide which will freeze out at cryogenic temperatures. The VSA sequence includes an adsorbent regeneration step whereby the impurity-saturated adsorbent is purged under vacuum with a purge gas. The resulting impurity-depleted air feed is fed to a cryogenic distillation column for rectification into a gaseous nitrogen overhead and a liquid oxygen bottoms. A waste stream from the distillation column is expanded, warmed against the impurity-depleted air feed to recover its refrigeration and subsequently recycled as the purge gas to the VSA unit. A key to the present invention is that the waste stream is expanded to the required sub-ambient pressure level in the cryogenic portion of the process.

Abstract: A device and method for cryogenic cooling of electronic components. A mixture of a first non-condensible gas and a second condensible gas is provided within an insulative housing. The non-condensible gas mixture has a partial pressure equal to the desired saturation pressure of the condensible gas. The insulative housing also includes an immersion chamber for housing electronic components. The immersion chamber preferably comprises two retainer parts and provides an module retainer top and a lower coldplate retainer bottom.
