Abstract: The present disclosure relates to methods and apparatuses sensing emitted light caused by fluorescence of adhesive to determine characteristics of absorbent structures during the manufacture of absorbent articles. Some absorbent articles may have absorbent structures that include an absorbent core disposed between a topsheet and a backsheet. And one or more of the absorbent structure components may be assembled with adhesive that fluoresces when excited by ultraviolet light. Aspects of the present methods relate to an inspection system that may be configured to interact with, monitor, and/or control a converting line. The inspection system may include a radiation source that illuminates a surface of an absorbent structure with ultraviolet light. A sensor may be adapted to receive light caused by fluorescence of the adhesive while being irradiated with the ultraviolet light. In turn, the inspection system may determine characteristics of the absorbent structure based on the detected emitted light.

Abstract: A two-phase working fluid, having a liquid phase and a gas phase, is purged of non-condensable gas prior to being used to charge a closed thermal management system, improving the heat transfer performance of the thermal management system. The liquid phase of the two-phase working fluid is exposed to conditions that cause non-condensable gas to separate from the two-phase working fluid. The non-condensable gas is vented, and two-phase working fluid that vaporizes under the conditions is captured.

Abstract: A thermosiphon system includes a condenser and an evaporator fluidically coupled to the condenser by a condensate line. The evaporator includes a housing having an opening to the condensate line, a wick located in the housing, and a flow restrictor located in the housing configured to restrict flow of a working fluid from the condensate line onto a portion of the wick.

Abstract: Various embodiments are directed to apparatuses for inspecting an on-line product web moving relative to the apparatus in a machine direction. The apparatuses may comprise a line-scan camera defining a field of view and positioned such that the field of view includes a portion of the product web. A camera control system may be in electronic communication with the camera and may be configured to receive from the web velocity sensor web velocity data indicating a velocity of the product web and convert the web velocity data to a line trigger signal. The line trigger signal may indicate a temporal frequency of camera image captures necessary to achieve a constant machine direction pixel resolution. Additionally, the camera control system may be configured to receive product position data and generate a frame trigger signal considering the product position data. The frame trigger signal may indicate a break between image frames.

Abstract: The present invention is a method and apparatus for sampling a high-temperature gaseous process stream containing components with high boiling points. The sampling system is especially suited for instruments having extremely low pressure chambers, such as mass spectrometers. The invention reduces the condensation of high boiling point components of the sample in the sampling system without the necessity of maintaining extremely high temperatures. The gaseous sample is passed through an orifice from the high temperature stream into a lower-temperature zone of the sampling system where a low pressure is maintained by a vacuum pump. The low pressure reduces the boiling point of the sample components so they may be maintained in a gas phase without excessive heating. The low pressure sample is then introduced into an instrument chamber through a sample introduction valve.
