  • Composite artificial log
    Patent number: 5284686
    Abstract: The present invention is directed to a composite artificial log for use in gas-fired artificial log fireplace assemblies or stoves, and more particularly, to a composite artificial log which has a ceramic concrete section molded to resemble a real log and having a relatively high thermal conductivity, which radiates a substantial amount of heat to the surroundings when heated, and one or more ceramic fiber sections having a relatively low thermal conductivity, which glow visibly when heated above about 1470.degree. F.
    Type: Grant
    Filed: February 27, 1991
    Date of Patent: February 8, 1994
    Assignee: Yale and Valor p.l.c.
    Inventor: Ian Thow
  • Gas-fired artificial log assembly
    Patent number: 5069200
    Abstract: The present invention relates to a gas-fired artificial log assembly for use in fireplaces or stoves, and more particularly to an improved gas-fired artificial log assembly which visually simulates, in a realistic fashion, a fire in a fireplace or stove stacked with generally horizontally disposed artifical logs, and which at the same time supplies substantial space heat to the surrounding room environment.
    Type: Grant
    Filed: February 27, 1991
    Date of Patent: December 3, 1991
    Assignee: Valor Incorporated
    Inventors: Ian Thow, Ajay K. Gupta
  • Composite artificial log
    Patent number: 5026579
    Abstract: The present invention is directed to a composite artificial log for use in gas-fired artificial log fireplace assemblies or stoves, and more particularly, to a composite artificial log which has a ceramic concrete upper section molded to resemble a real log and having a relatively high thermal conductivity, which radiates a substantial amount of heat to the surroundings when heated, and a ceramic fiber lower section having a relatively low thermal conductivity, which glows visibly when heated above about 1470.degree. F.

  • Gas-fired artificial log stove assembly
    Patent number: 4971030
    Abstract: The present invention relates to a gas-fired artificial log stove assembly, and more particularly to a gas stove assembly which visually simulates, in a realistic fashion, a traditional fire in a gas-fired stove stacked with horizontally disposed artificial logs, and which at the same time supplies substantial space heat to the surrounding room environment by heating room air circulated through a heat exchange mechanism.
