Abstract: According to various embodiments, a document storage tray includes a tray body and a document panel defining a document storage region. The tray further includes two internal alignment rails disposed in the interior of the tray body. The internal alignment rails are configured to facilitate an alignment of documents that are stored in the document tray via a plurality of alignment rods coupled to the rails and a plurality of document storage sleeves, configured to receive and house documents. A document stored in the document tray may be viewed, read, or accessed without requiring removal from the document storage tray. In this way, the embodiments may save the user time and allow the user to store and organize documents in a manner that will preserve the organization when the document is viewed or read.

Abstract: A pneumatic engine for metering or controlling of flow of compressed gas. is disclosed. In certain embodiments, the flow may be used to sound a whistle. The engine may include a body comprising a first chamber having an exit aperture, a second chamber having an entrance aperture, and a bolt aperture connecting the first chamber to the second chamber. A bolt may be positioned within the bolt aperture and extending into the first chamber and into the second chamber. The bolt may comprise a conduit extending therewithin. The conduit may place the first chamber in fluid communication with the second chamber. The bolt may selectively travel within the body through a range of motion. The range of motion may comprise a first position wherein the bolt blocks the exit aperture and a second position wherein the bolt does not block the exit aperture.

Abstract: A pneumatic gun sized and designed to appear like and operate in a manner similar to a conventional handgun. The gun may include a removable magazine storing projectiles and propellant. The entire magazine may be small enough to fit into a handle of the gun (e.g., with a pistol grip). The magazine may be integrated with propellant and projectile portions locked together or separable. Standard carbon dioxide cartridges fit within the magazine. Projectiles may be staggered to increase the maximum magazine load. A user may selectively release just the projectile portion of the magazine, in order to leave the propellant undisturbed until fully expended. The magazine may be completely removed from the gun without substantial loss of propellant.

Abstract: A paintball gun is sized and designed to appear like and operate in a manner similar to a conventional gun. A dual-action firing bolt moves forward, assisting in launching a projectile, under cast pressure. The bolt then releases the compressed gas to carry the projectile down the barrel. Return springs operate to move the bolt and its valves to a ready-to-fire position. Similarly, trigger actuation mechanisms are spring-actuated to return to the ready-to-fire position. A removable magazine stores projectiles and propellant. The magazine is small enough to fit into a handle of a pistol. A user may selectively release just the projectile portion of the magazine, in order to leave the propellant undisturbed until fully expended. The magazine can be completely removed without substantial loss of propellant.

Abstract: A new and improved indexing table for supporting a workpiece on a machine tool and the like includes a base with a workpiece supporting table carried on a support shaft journaled for rotation to index the workpiece for machine tool operations. A drive system is provided for rotating the table in one direction about a longitudinal axis of the support shaft and an indexing wheel is provided on the shaft having a plurality of index slots spaced angularly around the periphery for securing the table in selected indexing positions. A shot pin is provided for engaging selected slots in the wheel to lock the table in a fixed position and when the shot pin is retracted, the table is then permitted to rotate toward a next indexing position.
