Abstract: An anti-spill funnel assembly which includes an outer reservoir funnel having a center funnel positioned therein. The outer reservoir funnel includes a cone-shaped portion having a spout extending downwardly therefrom. The center funnel includes a cone-shaped portion having a hollow stem extending downwardly therefrom. This center funnel also includes a spout extending downwardly from the lower end of the cone-shaped portion thereof. The hollow stem portion has a plurality of vertically disposed slots formed therein. When the funnel assembly is being used to fill a container or a piece of equipment, the spouts of the reservoir funnel and center funnel are inserted downwardly into the fill opening of a container or equipment. As liquid is poured into the container or equipment, any overflow liquid is passed upwardly into the outer reservoir funnel to prevent a spill.

Abstract: A method for transporting a swab through a pipeline, or through an insert within a pipeline, according to he present invention may include coupling a swab launcher to the pipeline, the swab launcher having a launch chamber with a first inner large enough to receive a swab when the swab is substantially uncompressed and a narrowing portion configured to compress the swab to fit within the pipeline, inserting the swab into the launch chamber, pressurizing the launch chamber with a compressed fluid behind the swab, and advancing the swab with the compressed fluid through the narrowing portion and into the pipeline.

Abstract: An electronic muffling device is disclosed for suppressing the noise emitted by an outlet of an exhaust pipe of an engine. The device comprises a housing having an outlet and a plurality of audio transducers. The transducers supply anti-noise to cancel detected unwanted noise. A microphone appropriately positioned to detect residual noise is coupled to a cancellation signal generator, which controls the anti-noise generated by the transducers. Anti-noise and unwanted engine noise propagate through a front volume within the housing so that exhaust gases are transmitted through the housing, but engine noise is canceled before leaving the housing. Exhaust gas may be transmitted into the housing, or may be passed through the housing without leaving the exhaust pipe. In either embodiment, engine noise enters the front volume and is canceled.
