The safety system also has a boom deflection detector for detecting deflection of the boom, such as deflection caused by collision of the boom with a vehicle. A control system is provided for actuating the boom operator to move the boom to the up position whenever deflection is detected.

Abstract: A modified cartridge assembly including a projectile having a gas generator proximate its aft end. The projectile includes an aft closure having a cavity filled with gas generating material. The gas generating material is ignited around the time the projectile exits the weapon's muzzle. The gas generating material then burns while the projectile is in flight, spewing pressurized gas into the wake region immediately behind the projectile. The pressurized gas reduces the projectile's base drag.

Abstract: A modified projectile round which is configured to function with a propellant cartridge such as described in U.S. Pat. No. 7,004,074. The projectile assembly uses a High-Low gas pressure cartridge to launch the projectile. When the high pressure cartridge is ignited, hot propellant gases rupture a burst cup and shoot propellant gases toward the aft end of the projectile. The hot propellant gases impinge against a delay carrier located in the aft end of the projectile. The contents of the delay carrier are thereby ignited. The delay carrier includes one or more delay columns ultimately terminating in an igniter charge. The delay columns burn as the projectile is in flight. A specified amount of time later, the igniter charge ignites an ignitable payload—such as a marker flare candle.

Abstract: An anchor having an internal passage defined by a revolved wall profile. The anchor is conceptually divided into four regions: a neck region, a transition region, a mid region, and a distal region. Each of these regions has its own design considerations. A portion of a parabola is used to define at least part of the revolved wall profile. The parabolic portion is preferably used in at least the neck and mid regions. In order to create a tangency condition proximate the neck anchor boundary, the parabola used to create the wall profile is angularly offset from the wall profile's axis of rotation.

Abstract: A smoke production system for a model locomotive capable of accurately simulating the exhaust characteristics of an actual locomotive. The present invention accomplishes this by monitoring the rotation to the flywheel of the electric motor used to drive the drive wheels of the model locomotive. Various devices may be used to monitor the rotation of the flywheel. For example, a magnet is employed on the flywheel and a magnetically-reactive element such as a reed switch or Hall effect sensor is positioned adjacent to the flywheel. Alternatively, an opticoupler or cam may be used to track the rotations of the flywheel. A controller counts the rotations of the flywheel and actuates a smoke production device to emit smoke four discrete times for every rotation of the model locomotive's drive wheel.

Abstract: A vacuum chamber with an innovative wall structure. Instead of a conventional homogenous wall structure, the invention uses an array of internally-pressurized, thin-walled cells to contain an enclosed volume. The walls are arranged so that when a vacuum is present in the enclosed volume, the cell walls are placed primarily in tension. In this way the likelihood of buckling instability is substantially reduced. The result is a much lighter vessel compared to a conventional homogenous wall vessel of similar strength.

Abstract: A dispenser system having an integral sealing mechanism for resealing a severed end of a moisture-activated medical bandaging product. A sliding door closes the front of the dispenser system. The sliding door is raised and lowered by a handle preferably having a mechanical advantage. When raised, the sliding door's lower extreme defines a dispensing opening with the bottom of the box. A length of medical bandaging product can be pulled through this opening. When a user closes the door, the door's bottom extreme forms a tang and clevis interface which pinches the sleeve of the medical bandaging product and thereby form a moisture proof seal.

Abstract: A gauge mount for a motorcycle with a gauge encasement attached to a triple tree and one or more gauge mount locations attached to the gauge encasement. The gauge mount locations are located on the rearward facing side of the triple tree, facing the seat of the motorcycle. Each gauge mount location is adapted to receive a gauge housing. Each gauge housing connects a gauge to the gauge encasement. The gauges are preferably tilted upward to be more easily viewed by the rider while operating the motorcycle.

Abstract: A carrying case for transporting fishing equipment from one location to another. The carrying case generally comprises an external container and an insert insertedly situated within the external container. The external container is substantially cylindrical in shape with an open top and a closed bottom. The insert includes a lid, a base, and a support connecting the lid to the base. A plurality of cutouts are provided in the lid of the insert for receiving the shafts of a plurality of fishing rods. A plurality of seats are provided along the base of the insert for receiving the handles of the fishing rods. A storage space is also provided between the base of the insert and the base of the external container for storing other fishing equipment including fishing tackle. A series of ribs are provided along the walls of the external container near the base of the external container for mating with the base of the insert.

Abstract: A knife with a spring-assisted articulation mechanism for assisting the user in the folding and unfolding of the blade from the pocket of the liner. The spring-assisted articulation mechanism also helps retain the blade in the folded position to prevent the blade from becoming unintentionally unfolded. The knife includes a pocketed liner and a blade attached to liner at one end of the liner by a pivot pin. The blade has a pointed end and a base end, the base end pivotally secured to the second end of the liner by the pivot pin such that the blade is capable of pivoting between a folded “closed” position and an unfolded “open” position. A guide pin is also attached to the blade of the knife at the base. A spring is provided to exert a closing force on the blade when the blade is in the closed position and an opening force on the blade when the user moves the blade into a partially open position.

Abstract: A nested bushing coupling for attaching a plumbing component to a conduit. The assembly includes at least one or more nested bushings having off-centered openings which may be situated at various orientations within a receiver.

Abstract: Cable terminations having features which reduce stress in the transition between the potted region and the freely flexing region of a cable when the cable flexes laterally with respect to the anchor. Several favorable geometries are disclosed. The use of a supplemental buffer material to reduce stress is also disclosed.

Abstract: A rotating pedestal with an integrated locking mechanism configured to lock the pedestal in a desired angular position. The pedestal incorporates a soft heat-resistant top rotatably connected to a fixed base. The integrated locking mechanism is a sliding latch mounted in the base.

Abstract: A system for generating realistic train sounds which are synchronized with the motion of a model train. A sensor is placed aboard the model train to sense the position of desired components, such as the driving pistons of a model steam engine. Preferably, sound data is gathered and transmitted as a radio frequency signal from the model train. The radio frequency signal is received by an external receiver/amplifier. This component amplifies the synchronized sounds and plays them through a subwoofer which is capable of producing deep and resonant sound.

Abstract: An integrated bandaging system for encircling the abdomen of a horse. A ventral access opening selectively provides access to the horse's abdomen while the bandage remains in place. This ventral access opening is normally covered by a ventral window cover. However, the window cover may be easily opened so that an old dressing can be removed, an abdominal wound can be cleaned, and a new dressing applied. The invention has four major components: a main wrap, a saddle bridge, a ventral window cover, and a brace. The main wrap is easily placed around the horse's abdomen and secured using VELCRO® fasteners. It includes the ventral access opening. The saddle bridge attaches over the top of the main wrap and adjustably applies tension to the horse's mid section. The ventral window cover attaches over the ventral access opening and provides further adjustment of the tension on the abdomen. The brace applies over the points of the horse's shoulders, between the front legs, and over the ventral chest region.

Abstract: A cutting blade assembly incorporating two lawnmower cutting blades and a holder configured to hold the lawnmower cutting blades in perpendicular orientation with respect to each other. The holder does not occupy any space on the lawnmower blade mounting shaft and results in less rotational inertia than conventional mounting hub designs.
