Abstract: A pump assembly for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The pump is configured into two parts, an impeller assembly and a drive assembly, that are configured to couple together. The impeller assembly is isolated from the drive assembly and can be easily replaced to ensure a sterile fluid path is maintained for the eyewash fluid. The drive assembly can be fluid powered or an electric motor as desired. The present invention allows a plumbed eyewash station to be retrofitted to use a sterile eyewash fluid. The present invention can also be used in portable eyewash station units too.

Abstract: A mounting assembly for attaching an accessory to a dovetail rail interface on a firearm includes a body having a lower portion and an upper portion. The lower portion is configured to engage the dovetail rail interface and the upper portion is configured to receive and retain an accessory such as a scope or aiming device. A spring dampening structure resides within the body of the assembly wherein dampening structure is configured to dampen shock waves and harmonic vibration transferred into the body from operation of the firearm. A clamping assembly is configured to releasably clamp the body to the dovetail rail interface.

Abstract: The proposed invention is a new bolt and gas release valve mechanism for a projectile launching device, such as a paintball marker, that uses significantly less gas per shot than prior art devices. The open gas chamber between the projectile, such as a paintball, and the gas release mechanism is eliminated thereby requiring much less gas to be used for each launch of a given projectile. Thus, only the launching gas to propel the projectile is needed and not the additional gas required to fill the chamber in the bolt directly behind the projectile. This enables desirably smaller gas supply tanks to be used during use to launch the same number of projectiles. Also, with the present invention, more projectiles can be launched using the same gas supply tank.

Abstract: A modular hand guard assembly serves both as a hand guard system and as an integrated interface system for mounting various weapon accessories and attachments thereto. The modular hand guard assembly includes a removable forward rail section that can be removed from the forward portion of the hand guard to provide for the installation of additional weapon accessories such as lights, optics or lasers in highly a desirable forward location adjacent to the barrel of the weapon. The modular hand guard assembly further includes a removable lower hand guard to provide access to the barrel of the firearm and an integrated modular switching and control system for use in connection with the various powered accessories mounted thereto.

Abstract: A method is provided for forming a feedstock material for use in net shape molded component that includes an integral metallized coating or layer on the exterior surface thereof. The feedstock includes a carefully matched mixture of polymer resin and a metallic alloy that is suitable for use in a molding method that includes melting and injecting the material into a mold cavity under pressure. Due to the differential in material viscosities, the metal tends to migrate to the outer surface of the molded part when placed under pressure, ultimately creating a net shape molded part having a polymer core with a metallic layer at the exterior surfaces thereof.

Abstract: A method for the elimination of carbon dioxide from waste gases includes the following steps. First, waste gases, which include carbon dioxide, are provided from a source for waste gases. Next, the waste gases are contacted with an absorbent composition that includes perfluorodecalin solution. The waste gases, especially the carbon dioxide, are then absorbed by the absorbent composition. The absorbent composition thereby absorbs the waste gases to eliminate the carbon dioxide.

Abstract: A folding front sight for a firearm includes a laser aiming device within the folding sight frame. The folding front sight includes a base, and a sight frame having a front sight post. The sight frame is movable between an upright deployed position, and a stowed position. A laser aiming module is mounted within the sight frame and is movable with the forward sight frame such that when the forward sight frame is in an upright deployed position, the laser aiming module is in a stowed position, and further such that when the forward sight frame is in a stowed position, the laser aiming module is in a deployed position. The device further includes a power source and a switch for selectively energizing said laser aiming module to output an aiming beam.

Abstract: A method and system is provided that controls pet access to various different locations and/or objects. In a preferred embodiment, the present invention provides an automated system whereby pets wearing an ID tag are allowed access to various locations and/or objects, such as food contained within a feeder dish for example, while a sensor system, responding to the presence of other animals or people, causes the device to close preventing unauthorized access thereto. The feeder further includes one or more sensors using ultrasonic, infrared technology or both in combination for the identification of both tagged and non-tagged animals or children. Further embodiments employ the system to control access to litter boxes, pet toys, pet watering systems, pet gate access, pet containment systems or pet doors.

Abstract: Raw material such as food waste is scanned by a metal detector (11) and objects or containments removed, the food waste is then ground or macerated by a disintegrator (13), and passed to a live steam kettle (14), then passed to an in-line heater (15) wherein it is raised to and maintained at 80% for 20 minutes. The product is pumped to a three-phase decanter centrifuge (16) where it is separated into solids, water waste and tallow (oily product). The latter is pumped to storage tank (20), using a centrifugal pump (21), while water waste is discharged to effluent while solids are discharged to a container (18).

Abstract: An accessory module is installed between a weapon accessory (optical sighting device) and its corresponding mounting interface. The accessory module includes a body having a lower surface which is configured and arranged to mate with the corresponding upper surface of the mounting interface and an upper surface that includes a seat that is configured and arranged to conform to and receive the outer surface of the weapon accessory. The accessory module includes electronic accessories, such as for example, a flashlight configured to emit visible white light, colored light and/or infrared light. Further, the accessory module may include laser devices therein such as a laser sight, an infrared laser for night vision targeting, or a laser range finder device. The accessory module may also be configured to include a taser and/or a compact video camera.

Abstract: The present invention is a method for the allocation of data on physical media by a file system that eliminates duplicate data. Efficient searches are employed using a unique algorithm when a compare on hash is used to achieve realtime operation of the file system. The in memory feature of the invention allows the search to be performed in constant time. Also, the on disk representation of search structures enables the present invention to maintain these critical search structures in a highly efficient, self-consistent and resilient manner.
