Abstract: A method is provided to crimp a sheet having, before crimping, a thickness, a moisture, a composition, and a width, the method including: obtaining one pre-crimping sheet characteristic among the thickness of the sheet, the moisture of the sheet, the composition of the sheet, and the width of the sheet; crimping the sheet to form a plurality of corrugations on the sheet, the crimping including providing a pair of crimping rollers defining a nip therebetween, the nip having a nip size, and inserting the sheet in the nip; evaluating a post-crimping characteristic of the sheet after crimping; and varying the nip size on the basis of the obtained one of the pre-crimping sheet characteristic, and on the basis of the evaluated post-crimping sheet characteristic. An apparatus to crimp a sheet is also provided.

Abstract: An aerosol-generating article is provided, including: a rod of aerosol-generating substrate including an aerosol former, the substrate having an aerosol former content of greater than 10 percent on a dry weight basis; a hollow tubular support element immediately downstream of the rod; and a first aerosol-cooling element downstream of the support element and including a hollow tubular segment including peripheral and transverse walls at a location between upstream and downstream ends of the tubular segment such that it defines a first cavity upstream of the transverse wall and a second cavity downstream of the transverse wall, the transverse wall including openings establishing fluid communication between the first and second cavities, and the peripheral wall including openings located at longitudinal positions away from the transverse wall so that fluid communication between an exterior of the tubular segment and at least one of the first and second cavities is established.

Abstract: An aerosol-generating article is provided, including a rod of aerosol-generating substrate; an aerosol-cooling element downstream of the rod and including a hollow tubular segment including a peripheral wall, the segment extending along a longitudinal axis and having a downstream end in fluid communication with an upstream end, the segment further including at least one elongated protrusion extending from the peripheral wall into an interior of the segment, the protrusion extending longitudinally from an upstream position on the wall to a downstream position on the wall; and a wrapper circumscribing the rod and the aerosol-cooling element, the protrusion being a deflecting fin configured to change a direction of flow of an aerosol flowing from the upstream to the downstream end the segment, and the fin being twisted along a length of the segment.

Abstract: An aerosol-generating article is provided, including: a rod of aerosol-generating substrate including an aerosol former, the substrate having an aerosol former content of greater than 10 percent on a dry weight basis; a hollow tubular support element positioned immediately downstream of the rod; an aerosol-cooling element downstream of the support element, the aerosol-cooling element extending all the way to a downstream end of the article, the aerosol-cooling element including a hollow tubular segment having a transverse wall at a location between an upstream end and a downstream end of the hollow tubular segment, such that it defines a first cavity upstream of the transverse wall and a second cavity downstream of the transverse wall, and the transverse wall including one or more openings establishing a fluid communication between the first cavity and the second cavity.

Abstract: A method of controlling an uninterruptible power supply system to increase component life includes decreasing a maximum output power limit of the uninterruptible power supply system when a temperature that the uninterruptible power supply system is experiencing has increased and increasing the maximum output power limit when this temperature has decreased. In an aspect, this temperature is ambient temperature of an equipment enclosure of the uninterruptible power supply system in which at least a rectifier and inverter of the uninterruptible power supply system are located. In an aspect, the method further includes upon the system going into an overload condition, determining an overload time limit based upon the temperature, the overload condition and an initial load condition. In an aspect, the method further includes upon the system going into a back-up power mode, determining a battery autonomy based upon the temperature.
