Example systems and methods for aligning roll-up door curtains are disclosed. An example door includes a roller that is rotatable about an axis. The door further includes a curtain having a wrapped section wrapped around the roller and an unwrapped section extending tangentially away from the wrapped section. The unwrapped section adjoins the wrapped section at a first point proximate a first end of the roller and at a second point proximate a second end of the roller. The axis is closer to the second point than to the first point when the curtain is at the intermediate position. In some examples, the door includes a guide member to guide the curtain on to the roller.

A system and a method is provided for improving a baseball player's batting swing. Preferably, the system can be utilized to teach a player to swing with power and with a slight upstroke to increase the chances of getting a powerful line drive hit. The system includes a post upwardly extending from a support base. Preferably, the post is adjustable to increase or decreased in height to match the size of the player utilizing the system. A channel is attached at upper portion of the post and includes a means for providing resistance, such as bristles, that protrude generally upwardly from the channel base. A second similar channel with a resistance means is mounted above and facing the first channel such that there is a gap between the two resistance means. Preferably, the channels are rotatably mounted to the post such that the angle of the path between the resistance means can be adjusted to provide a slight increase in elevation that will result in a slight upswing by the player utilizing the training system. A channel support is utilized to fix the position of the two channels relative to each other. Preferably, the channel support is shaped to guide and direct a player's swing down and through the resistance means of the channels. Preferably the channel support includes a resistance adjustment that can increase or decrease the resistance on a bat passing through the channels.

A filter making apparatus includes a positioning device having a passageway therethrough, with the passageway guiding a continuous flavor element such as a continuous strand of textile material from an inlet of the passageway to an outlet of the passageway. A liquid flavorant is introduced into the passageway at a desired flow rate and the strand of material carries the supplied liquid flavorant out of the positioning device at a rate substantially equal to the desired flow rate. A portion of the passageway can form a bath of the liquid flavorant supplied to the passageway through a separate inlet at approximately atmospheric pressure. A portion of the positioning device guides the continuous strand of material through the bath, or guides the strand to pass along the bottom of the passageway, and the saturated or partially saturated strand of material then exits from an outlet of the passageway to a point in the path of filter tow material that is being converged to form a filter rod.

An example of a horizontal side-moving door with a side-winding or horizontally translating curtain includes an upper seal comprising an upper edge of the curtain sliding within a groove of a seal guide. To protect the door in the event of an impact, at least a portion of the curtain's upper edge can restorably pull out from within the groove. To avoid damage in certain situations, the seal guide might resiliently deflect as well. After an impact, the curtain's upper edge is automatically fed back into the groove by simply opening and closing the door. During normal operation, the curtain's upper edge advantageously deflects in response to air pressure against either side of the door. In some examples, the seal guide is of a uniform cross-section, which makes the seal guide easy to manufacture by way of a conventional plastic extrusion process.
