A tubular tissue scaffold is described which comprises a tube having a wall, wherein the wall includes biopolymer fibrils that are aligned in a helical pattern around the longitudinal axis of the tube where the pitch of the helical pattern changes with the radial position in the tube wall. The scaffold is capable of directing the morphological pattern of attached and growing cells to form a helical pattern around the tube walls. Additionally, an apparatus for producing such a tubular tissue scaffold is disclosed, the apparatus comprising a biopolymer gel dispersion feed pump that is operably connected to a tube-forming device having an exit port, where the tube-forming device is capable of producing a tube from the gel dispersion while providing an angular shear force across the wall of the tube, and a liquid bath located to receive the tubular tissue scaffold from the tube-forming device. A method for producing the tubular tissue scaffolds is also disclosed. Also, artificial tissue comprising living cells attached to a tubular tissue scaffold as described herein is disclosed. Methods for using the artificial tissue are also disclosed.

A bicycle suspension system including a travel adjustment apparatus. The bicycle suspension system includes a piston tube and a piston assembly slidably disposed in the piston tube forming a shock-absorbing mechanism. The piston assembly is in contact with the piston tube. The travel adjustment apparatus includes first and second fluid chambers, a fluid valve mechanism for controlling fluid flow between the first and second fluid chambers, and an actuating assembly operatively connected to the fluid valve mechanism operable between at least two rider-selectable travel settings to operate the fluid valve mechanism between at least two valve settings corresponding to the rider-selectable travel settings. The first and second fluid chamber are configured such that operation of the fluid valve mechanism between two of the at least two valve settings permits the piston assembly to be moved from a first initial position relative to the piston tube to a second initial position relative to the piston tube such that the suspension system changes from a first of the at least two amounts of travel to a second of the at least two amounts of travel.

An in-line continuous feed sleeve labeling machine labels containers, such as beverage containers, in an in-line fashion maintaining the elevation of the containers during their linear transport. The in-line continuous feed sleeve labeling machine of the present invention receives bottles in flood feeder or linear fashion. A timing screw or the like properly separates, and both spatially and temporally disposes, the containers for sleeving. The timing screw propels the containers onto a pedestal system. The pedestals of the pedestal system maintain their horizontal nature due to offset pivotable attachments to the track system upon which they travel. A sheet of film is unspooled from an unwind roll and passed through a tube forming apparatus that overlaps the edges of the film. The overlapping edges completing the tube enclosure are connected using ultrasonic welding or the like. The sleeve is then passed to an iris carrier. In coordinated fashion with the travel of the pedestal system, iris carriers carrying sleeves upon articulating radial arms descend upon the bottles. Once the label sleeve has reached the appropriate point (generally adjacent to the central portion of the bottle), the iris carrier allows the label sleeve to engage the central portion of the bottle. Frictional attachment or otherwise allows the finger rods of the iris carrier to pull away from the sleeve as the iris carrier continues to descend down towards the pedestal. The sleeve then becomes attached to or engaged by the bottle until the finger rods of the iris carrier free themselves from the sleeve label. A container stabilizer may provide lateral bottle support and aid the ensleevement process. The finger rods then dilate to better disengage the bottle as the iris carrier ascends up and away from the bottle. The bottle is then transported to an exit conveyor having been properly sleeved, while the iris carrier returns to transport another sleeve.
