  • Freeze protection through volume donation
    Patent number: 11451039
    Abstract: Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within a braided/woven layer that can be sealed to provide longitudinal strength and a snag resistant durable and flexible outer coating. The assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.
    Type: Grant
    Filed: April 28, 2022
    Date of Patent: September 20, 2022
    Inventors: Steven Haagenson, John Huber, Jr.

  • Freeze protection through volume donation
    Patent number: 9733446
    Abstract: Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within an outer non-conductive durable outer coating, with a pull cord extending therethrough, wherein the assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.
    Type: Grant
    Filed: May 20, 2016
    Date of Patent: August 15, 2017
    Inventors: Steven Haagenson, John Huber, Jr.
  • Stepwise reduction of p-nitrophenol
    Patent number: 4264525
    Abstract: A stepwise reduction and acetylation process for the production of pure N-acetyl-p-aminophenol (APAP) from p-nitrophenol in an aqueous system that avoids the need for strong acids or excess acetic anhydride.
