A tank including a fluid reservoir, a communication module, a controller, and at least one sensor. The fluid reservoir is configured to be in fluid communication with a cable segment. The communication module is configured to communicate with an external device. The sensor is configured to detect an injection parameter value, encode the injection parameter value in a sensor signal, and send the sensor signal to the controller. The controller is configured to automatically instruct the communication module to transmit information to the external device based on the injection parameter value.

Fluid injection system with smart injection and receiver tanks

A system including a processor and sensor for installation inside an underground vault. The sensor monitors a parameter inside the vault and sends a monitoring signal to the processor. Based on the monitoring signal, the processor may provide data to a memory for storage and/or control signals to an interface for transmission to an external device located within the vault. The control signals instruct the external device to modify the environment inside the vault. The sensor may be positioned inside an enclosure, which is inside a housing. An air moving device moves air into or out of the enclosure thereby drawing air from the vault into the enclosure before the sensor monitors the parameter. A heat generating component may be positioned inside the housing and when generating heat prevents moisture from condensing therein. The system may include a power unit that draws power from a power source inside the vault.

Smart system for manhole event suppression system

A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based strand-block mastic, the conductor being surrounded by a polymeric cable insulation. The method including pre-injection of compressed gas into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation, and injection of a rejuvenation fluid into the conductor strands of the cable at a pressure less than the elastic limit of the cable insulation.

Method for injecting strand-blocked cable

A method for rejuvenating a strand-blocked cable having a conductor comprised of a plurality of conductor strands with interstitial volume therebetween blocked by a PIB based mastic, the conductor being surrounded by a polymeric cable insulation. The method comprising installing injection adapters that seal the cable ends of the cable and are usable to inject fluid into the interstitial volume between the conductor strands of the cable; elastically expanding the polymeric cable insulation through the application of pressure to the interstitial volume between the conductor strands of the cable; and injecting at least one injection fluid in which the PIB based mastic is mostly insoluble into the interstitial volume between the conductor strands of the cable.

To facilitate elastic deformation of the polymeric cable insulation, the cable may be heated to and maintained at a temperature of T1 above ambient during the injection.

A conveying system for conveying a conveyable material from a hopper where the system includes a fluid port located below the hopper outlet and in a vertical flow path into hopper outlet that can be momentarily opened for an on the go release of a charge of compressed air directly upward into the hopper outlet and into the underside of the bridge in the hopper to either disintegrate or unlock the bridged particles from each other thereby causing the bridged material to fall into the hopper outlet and into the conveying system where the material can be transported to a remote location or to remove any material that may be adhering to the wall during an emptying phase.

Conveying systems

A system for use with a manhole vault having an internal atmosphere, and, optionally, with a ventilation stack connecting the vault to an external atmosphere. The system includes a manhole cover, a ventilation pipe, and an air moving assembly. The cover has one or more through-holes extending between top and bottom surfaces. Each of the through-hole(s) is in fluid communication with the external atmosphere at the top surface. The pipe has a through-channel that extends between first and second openings. The first opening is positioned proximal to either an opening into the ventilation stack or at least one of the through-hole(s) at the bottom surface of the cover. The second opening is positioned in the interior of the vault. The device is configured to cause a portion of one of the interior and external atmospheres to flow through the through-channel toward a different one of the interior and external atmospheres.

Ventilation system for manhole vault

A system for circulating air inside a manhole vault. The system includes an air-moving device in fluid communication with the manhole vault and configured to circulate the air inside the manhole vault to prevent a concentration of combustible gasses or to enhance cooling therein.
