Abstract: According to examples, a printing system may include a guide rail and a carriage. The carriage may include a rotatable member supported on the guide rail. The printing system may also include a cleaning assembly mounted to the carriage and the cleaning assembly may have a scraper to scrape debris off at least a portion of the guide rail.

Abstract: A method of improvement of inhalation therapy including presenting audiovisual stimuli to a patient, where content of the audiovisual stimuli promotes a physiological response, such as an involuntary breathing response, such as a yawn. Also, an apparatus for improvement of inhalation therapy including an audiovisual stimuli presentation system, where the audiovisual stimuli presentation system presents audiovisual information to a patient, and where content of the audiovisual stimuli presentation system promotes a physiological response, such as an involuntary breathing response, such as a yawn. The method and apparatus may be particularly suited for a patient that is unable or unwilling to communicate with a respiratory therapist, such as pediatric patients or patients with a neurological disorder.

Abstract: A condensate agitator is provided for use in paper machine dryer cylinders. The agitator comprises a generally cylindrical open-work body which overlies portions of the interior surface of the dryer cylinder with its outer surface lying in flush engagement therewith. A modular agitator construction is also disclosed for facilitating installation of the agitator in a dryer cylinder without requiring the use of fasteners in accordance with a method for that installation which is also disclosed.

Abstract: The web-forming section of a twin-wire papermaking machine includes a plurality of sets of web deflectors. Alternate sets are disposed on opposite sides of a pair of forming carriers between which a water suspension of fibers is disposed. Each set of deflectors has a plurality of deflectors providing forming carrier guiding surfaces spaced along a gentle convex curve. The sets of deflectors are disposed to guide the forming carriers over a tortuous path through the forming section. The tension in the forming carriers presses the outer carrier against the inner carrier at each curve, expressing water from the suspension through the carriers. The expressed water is doctored off by the deflectors.
