  • Patent number: 7677266
    Abstract: A manifolded fail-safe hydraulic control system provides fail-safe operation of a pipeline valve using no more than a total of 45 proprietary parts in the system. The system controls the operation of a spring return actuator, which in turn strokes the pipeline valve from the normal operating position to the fail-safe position, or from the fail-safe position to the normal operating position. The system enables the valve to automatically stroke to its fail-safe position without external power.

  • Patent number: 7673655
    Abstract: A system and method for repairing and reinforcing a pipeline includes a pair of opposing composite wrap bands that are located on the external surface of the pipeline and positioned a predetermined horizontal distance from a defect area. A composite wrap is then applied over the bands to create a bridge that spans the bands and forms a cavity above the defect area. The bridge eliminates the need to clean the surface of the pipeline directly over the defect area. A second pair of bands located on the external surface of the bridge provides structural support. An actuator within the bridge monitors the pressure within the cavity and activates upon the presence of internal pressure, indicating a through-wall defect has occurred. A fitting may also be inserted into the bridge in order to pressurize the cavity and test the repair.

  • Patent number: 7669351
    Abstract: A dispenser for a sanitary shoe cover holds a stack of shoe covers with their resiliently elastic mouths in a stretched-open condition in a storage zone. Sanitary covers are carried individually from the storage zone stack to a dispensing zone. The individual shoe cover is automatically released from the dispenser in response to downward insertion of the shoe-covered foot into the stretched-open shoe cover, permitting the resiliently elastic mouth to gather into abutment with the shoe-covered foot. The process is automatically repeated to carry another individual cover to the dispensing zone in response to the upward removal of the sanitary-covered, shoe-covered foot from the dispensing zone.

  • Patent number: 7670462
    Abstract: A system and method whereby on-line cleaning of black oil heater tubes and delayed coker heater tubes may be effectuated by injecting a high pressure water charge through the tubes during normal process operations so as to prevent tube fouling and heater downtime. The high pressure water charge begins the on-line cleaning process once it enters the heater tube by undergoing intense boiling and evaporation. The cleaning occurs by two methods—a scrubbing action and a shocking action. The scrubbing action occurs because of the complete turbulence caused by the water charge's intense boiling within the heater tubes. The shocking action is caused by the expansion and contraction of the heater tubes resulting from the colder water charge flowing through the heater tubes which is then followed by the hotter process fluid flowing through the heater tubes.

  • Patent number: 7588050
    Abstract: A cap permanently indicates the occurrence of tampering with a gas service valve. A substantially square base has intersecting slots differently sized to confine correspondingly sized valve cocks against rotational motion. A dome on the base covers the slots and the valve cock. Two ties of adjustable length secure the base against the valve body. The base, dome and ties are of material which is permanently altered by application of force to disorient the mounted cap sufficiently to permit operation of the valve cock. Removal of excess portions of the ties makes reuse difficult, if not impossible. The dome may be transparent so that the orientation of the valve cock can be observed without removing the cap from the valve. Markings on the dome indicate the orientation of the valve cock when the cap was installed.

  • Patent number: 7575520
    Abstract: The present invention provides a tap (10) adapted for formation of female screw-threads in a plurality of metal parts. Each female screw-thread is capable of imparting translational motion to a threaded second member engaged therewith, the threaded second member having a matching male screw-thread and the translational motion occurring on relative rotation between the first metal part and the threaded second member. The tap (10) is fluteless and comprises a threaded portion (23) with a triangular form thread (11) with an angle of thread (gamma) in the range 29°-40° and radiussed crests (16). The present invention also relates to a method of using such a tap.

  • Patent number: 7546847
    Abstract: A plug for closing an opening in the sidewall of a pipe, including a base member having a radial flange portion, a tubular portion and an annular elastomeric seal member slideably received on the base member tubular portion and in engagement with the flange portion. A rigid compression member is slideably received on the base member tubular portion and in contact with the elastomeric member and has a frusto-conical circumferential surface. A plurality of rigid segmented slips are received on the compression member and have teeth for biting into the cylindrical sidewall when displaced on the frusto-conical surface. An actuation member is received on the base member tubular portion providing a surface in engagement with the segmented slips. A tightening nut can be tightened to cause the segmented slips to lock the plug in position and to sealably close the pipe cylindrical sidewall.

  • Patent number: 7532730
    Abstract: An improved dynamics processing control system clamps a level detected control signal at a level equal to a predefined threshold point. In one embodiment, a clamped level detected signal feeds a filter with very slow response characteristics. By comparing the difference between the input and the output of the system a differential control signal generated. The differential control signal is used to provide a continuously variable, program dependant output signal when the input signal drops below a threshold point. In another embodiment of the invention, both the attack and release times of the system are varied in response to a differential control signal.
