Abstract: A cooking fuel device includes a fuel container and a wick supporting member positioned at the top of the container. The wick supporting member substantially closes the fuel container and contains at least one aperture to communicate with the interior of the container. A wick formed from a piled fabric includes a burn portion and a fuel feed portion. The fuel feed portion extends through the aperture into the fuel in the container. A cover having a central aperture is positioned over the top of the container to define the burn area on the wick. A peelable lid is adhesively attached to the cover and the wick which when removed will raise the pile on the wick.

Abstract: A cooking fuel device includes a fuel container and a cover attached to the top of the container. The cover includes a central toroidal shaped aperture positioned over the top of the container to define a toroidal burn area for a fuel in the container. An optional wick positioned below the cover is formed from a piled fabric includes a burn portion and a fuel feed portion extending to the fuel in the container.

Abstract: A black powder flamespread tester is disclosed in which powder to be qualed is packed in a sample tube provided with a plurality of sight holes. Light sensors are disposed adjacent each sight hole and emit signals upon flame front passage of the sight hole. The sample tube is removably secured to an ignition head which contains an electrically actuated pyrotechnic squib. The squib discharges gases into a transition chamber from which the gases pass through orifices in an orifice plate, through a void volume into the black powder bed, which ignites the black powder. The ignition head is removably secured to a tester chamber in which the sample holder is received. Light sensors are housed in a separate fin which is removably received in an aperture in the tester chamber wall. After the squib gas ignites the powder bed, the output signal of each light sensor increases to saturation as the flame front passes its respective sight hole.
