Abstract: In some embodiments, a method for binding a book is provided. The method comprises mechanically stacking sheets of paper, each having notches in one edge, into an aligned book block having a spine. The notches are generally all facing the same direction and staggered in relation to each other. The method may further comprises positioning a cover such that an inner central portion of the cover abuts the spine and causing the central portion and the spine to adhere to each other.

Abstract: The invention teaches a paperback book-finishing apparatus comprising a collator, a cover trimmer (with optional scorer), a glue cutter, and a binder. The apparatus can automatically finish books of different thicknesses. The operations of cover trimming, glue cutting and placement, and collating are all carried out by aligning to a common alignment edge. The glue cutter cuts glue strips of variable width and the collator collates printed sheets by synchronized tamping. The apparatus can be used with in-line, on-demand page printers and in-line, on-demand cover printers. The apparatus can be used in book vending machines.

Abstract: A pop up sprinkler utilizes a diaphragm valve oriented in a vertical manner within the sprinkler water inlet. The valve has a circular bellows surrounding a core and is movable between an expanded position embracing the core and a relaxed position displaced from the core. In the displaced position water flow through the sprinkler is allowed, such flow passing about the core in a manner which creates minimal pressure loss in the valve.
