Abstract: An archery arrow/bolt pulling device designed for the safe, easy, non-destructive and one handed extraction of deeply embedded, complete arrow or bolt assemblies regardless of shaft diameter or arrowhead type from foam and other target materials. This device pulls with three surrounding gripping jaws in a coaxial path with the long axis of the arrow/bolt and the combined mechanical advantage power of lever, fulcrum and cam while overcoming the minimal movement of the load end of the lever by means of a ratcheting pawl and toothed pull rod.

Abstract: A method for removing internal moisture which tends to collect in the hulls, decks, stringers, transoms, bulkheads, spars, and other boat structures. Air injection bores are formed in the core or other boat structure in the vicinity of unwanted moisture. Pressurized injection air is injected into the bores through a plurality of air injection lines running from a source of pressurized injection air. The temperature of the air being injected into bores is varied as a function of the temperature and/or relative humidity of ambient air at or near the bores.

Abstract: Various disclosed embodiments relate to structures and methods for printing systems. In some embodiments, a device, e.g., a festoon, may be used to accumulate excess material. The festoon may be located between a print head and a finishing component to eliminate misalignment/mis-registration difficulties between printed images and finishing options. In some embodiments, registration images and other procedures may be used alone or in conjunction with the festoon placement to further reduce errors and waste.

Abstract: Disclosed is a reconfigurable obstacle system for a river channel in a river park. Each obstacle assembly includes a plurality of obstacles. Obstacles may include a hollow structural box, a strut channel frame and a plurality of connectors that cooperate to divert water when installed in a river channel. A plurality of connectors pass through the hollow structural box when holding the obstacle in position. The obstacle assemblies can be reconfigured as desired, e.g. increase amplitude of a wave, speed up water flow, change depth, etc.

Abstract: Disclosed is a whitewater park and whitewater park systems. A recreational waterfall system for traversal by watercraft that includes at least one headgate to produce a surge of water over a waterfall and to limit access to the waterfall by watercraft. A recreational watercraft launch that accelerates a watercraft while traversing said waterfall and a downstream crest a variable exit geometry causes the watercraft to be directed in an upward direction. A recreational waterfall has water flowing over a crest with variable cantilever determining a distance from the edge that the water flowing over the crest impacts water in the pool. A whitewater park has multiple routes of varying difficulties between pools.

Abstract: A tritium sensor and method are provided. The sensor involves the use of an electrode having a semiconductor coating that has properties selected to allow the passage of beta particles at the particular energy level for tritium through the semiconductor layer to a conductive electrode core and produce current. Current flow in the core can be measured by a current measuring device. The current flow can be correlated to the concentration of tritium in the gas surrounding the electrode to provide an indication of the amount of tritium present. The device can be used in a static system or a system in which the tritium containing gas flows. The apparatus provides real time readings of the tritium concentration in gas.

Abstract: A rotary sprinkler is provided that includes a housing having a riser assembly and a rotatable nozzle turret on an upper end of the riser assembly. The sprinkler includes an arc setting assembly that enables part-circle operation of the turret and a selector assembly that permits selection of either part-circle or full-circle operation of the nozzle turret where the components of the selector assembly are generally separate from the components of the arc setting assembly.

Abstract: A control system includes a controller having shared pins and unique pins for receiving and outputting signals from and to first and second memory devices. The first memory device includes signal lines which are electrically connected to shared pins, and the second memory device includes signal lines which are electrically connected to the shared pins together with the signal lines from the first memory device. The controller selectively inputs signals from and output signals to the first memory device and second memory device through the select shared pins.

Abstract: A sprinkler is disclosed for improved flow characteristics. The sprinkler has a sprinkler head rotatably supported for distributing water and defining a flow channel for directing water flow therethrough with reduced head loss. The flow channel has a smoothly tapered portion for receiving water and channeling the water towards an outlet in communication with a first nozzle for distributing the water. The flow channel with reduced head loss produces a greater throw distance at a lower trajectory with a lower flow rate and pressure. The flow channel may be formed within a flow channel member positioned within the sprinkler head. The flow channel member may cooperate with the sprinkler head to define a cavity allowing water to pass through the cavity from the flow channel for emission from a plurality of other nozzles.

Abstract: At least one rotating memory medium such as a hard disk is installed in a hard disk drive or the like. The disk drive has a controller, controller memory and one or more heads for writing and reading to and from one or both sides of the disk. The disk is scanned for defects as sector locations, servo wedges and other information are recorded on tracks on the disk. Some unused space is reserved around the track to compensate for the area lost to defects. If a defect is detected in a sector, the sector is split into first and second parts on either side of the defective space. The location of the defective space is recorded in the controller memory and is processed like a servo wedge. In this manner, only part of the sector is lost due to the defect.
