Abstract: A flexible cleaning lance safety apparatus is described as including a tripod support structure located close to an opening into an object to be cleaned. A flexible lance drive is fastened to the support structure for driving a high pressure fluid through a lance to the object to be cleaned. A snout tube is connected between the lance drive and an opening into the object to be cleaned. One or more micro pressure valves on each leg of the tripod support structure is operative to sense a predetermined force applied between the support structure and a support surface supporting the tripod support structure. When the predetermined force is sensed this causes the high pressure fluid to be diverted from the lance and the object to be cleaned to atmosphere.

Abstract: A pneumatic power generator configured for generating less than about 100 W for providing on demand power to a device connected to the power generator includes a pneumatic motor coupled to an alternator with a coupling member. The pneumatic motor has an inlet port configured to receive pressurized gas to rotate an output shaft. Rotation of the output shaft is transmitted to an inlet shaft of the alternator via the coupler member. As the pressurized gas causes the pneumatic motor, the inlet shaft of the alternator rotates to produce AC power. An electronics housing is coupled to the alternator and has an electronic board and at least one power storage device. The electronic board includes a rectifier configured to convert the AC power output from the alternator into DC power for storage in a power storage device, with power being provided from the power storage device on an on-demand basis.

Abstract: A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and a switching valve cartridge disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The cartridge comprises a cylindrical cartridge case having a front portion and a cup shaped rear portion, a cylindrical poppet slidably disposed within the cup shaped rear portion of the cartridge case, and a biasing member within the cartridge case between the front portion of the case and the poppet urging the poppet away from the front portion of the cartridge case.

Abstract: A camera skid and thrust nozzle assembly for supporting a camera while being positioned in a tubular pipe or conduit spaced from any wall of the conduit and permitting movement of the assembly along the conduit. The assembly includes a cage rotatably fastened to a high pressure fluid tractor nozzle, wherein the cage can rotate about an axis through the tractor nozzle. A camera support structure is fastened within the cage for rotation of the support structure about the axis independent of rotation of the cage. The camera support structure has a weight attached thereto for urging rotational orientation of the camera support structure within the cage according to a sensed external gravitational force on the assembly.

Abstract: A flexible lance drive device is disclosed that has, in a compact housing, a drive motor between an inner and an outer wall, a linear array of pairs of driven upper and lower drive rollers outside the outer wall coupled to the drive motor via shafts extending through both of the inner and outer walls. Each driven roller is fastened to its shaft via a quick release device. A drive sprocket is fastened to each shaft outside the inner wall. The drive motor is coupled to each of the drive sprockets via a serpentine belt carried outside the inner wall. The lower driven rollers are rotatably carried by the inner and outer walls. The upper driven rollers are rotatably carried by a block positioned between the inner and outer walls and coupled to the lower driven rollers by a pair of parallel links releasably biased by a piston driven linkage.

Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The method includes sensing a pneumatic supply pressure to a pneumatic lance drive motor at the motor during forward operation, sensing a pneumatic discharge pressure at the drive motor during forward operation, determining a difference between the pressures, comparing the difference to a predetermined difference threshold; reversing the drive motor direction for a predetermined time interval if the difference exceeds the threshold, and restoring forward operation after the predetermined time interval; and repeating the reversing and restoring operations until the difference no longer exceeds the predetermined difference threshold.
