Abstract: A barn curtain having a transparent panel and a non-transparent panel is prepared by a welding machine. The welding machine has an inner heater assembly including a first roller wheel, an inner plate assembly having a lower inner plate and an upper inner plate spaced apart from the lower inner plate in a vertical direction, and a heater, and a first roller assembly including a second roller wheel aligned with the first roller wheel. A side of a transparent panel is fed through the lower inner plate and a side of a non-transparent panel is fed through the upper inner plate. The plates are heated with the heater to partially melt the side of the transparent panel and the side of the non-transparent panel. The side of the transparent panel and the side of the non-transparent panel are pressed between the roller wheels and joined.

Abstract: An amphibious vehicle comprises a buoyant hull, a boat motor affixed to the hull to propel the amphibious vehicle in water, two or more powered wheel assemblies affixed to the hull to propel the amphibious vehicle on land, and two or more selectively rotatable arms affixing each wheel assembly to the hull. One or more of the wheel assemblies are affixed to opposing sides of the hull. Two or more selectively rotatable arms affix each wheel assembly to the hull. The arms affixing each respective wheel assembly are selectively rotatable in unison to move the respective wheel assembly between a lowered position and a raised position.

Abstract: Media files are often tagged, such as by XML or other tagging paradigms, in order to indicate aspects of certain portions of the media file. Disclosed herein, security policy tagging is provided that supports a logically nested or hierarchical structure. Tags may be time- and/or event-altered, such as when a user who is denied access at one point in time may be granted access at a later point in time. The need to amend the security policy based upon the passage of time is reduced or eliminated as portions, or sub-portions, of a media file that may be selectively tagged with security tags may be presented or downloaded based upon the security policy. The a security policy may incorporate rules that change permissions upon the passage of time or the occurrence of an event, without requiring the modification of the presentation, the security tags of the presentation portion, or the security tag associated with a parent portion of the presentation or the presentation itself.

Abstract: Tagging media streams allows topics and other items of interest to be readily identified. As provided herein, stateful tags are provided, which comprise a value determined from a link to another data source, such as a calendar, inventory, accounting, project management, or other application. Media streams, such as audio/video confines, may be tagged with stateful tags to identify items of interest and comprise a value that is dynamically determined. Subsequent playback of the media streams allows the stateful tags to be presented as comprising a then-current or other value, which may have changed since the time of the media stream's creation.

Abstract: Thrust augmentation apparatus for a propulsive gas jet 11 including: an outer augmentor housing 15 and an inner augmentor housing 21 arranged coaxially with the jet 11. A minor air flow 25 is drawn into the inner passage 24 by an ejector effect, that flow 25 driving turbine vanes 28 projecting inwardly but terminating short of the jet 11. The vanes 28 transmit drive to fan blades 13 in the outer housing 15 to promote a thrust augmenting air flow 14. As an alternative to turbine vanes 28, gas scoops 32 may be used to develop the energy for creating the air flow 14.

Abstract: Apparatus for separating, or de-nesting, the lowermost flanged container from a nested stack of flanged containers is characterized by a flange support member reciprocally movable from a first to a second rectilinear position. The flange support member has first and second flange support surfaces thereon, the second flange support surface being rectilinearly behind and in a vertical plane above the first flange support surface. In the first position, the first flange support surface supports the flanges of the lowermost container above an opening provided in a baseplate. As the flange support member rectilinearly displaces to the second position, a lifting surface lifts the flanges of the next-lowermost container onto the second flange support surface cotemporaneously with the withdrawal of the first flange support surface out of its supporting relationship with the flanges of the lowermost container.
