Abstract: An illuminated-heated ice fishing system. The system includes a plurality of sidewalls and a top wall in hinged communication and wherein the device is capable of folding up for storage. The system includes a heated lantern to heat and illuminate a spool of the device. The spool is removably affixed to a sidewall of the device and includes a reflective surface directed towards the interior of the device to reflect the light from the lantern. The sidewalls have a bottom portion comprised of a thermoplastic material for contacting the ice surface.

Abstract: The invention relates to a method for estimating the fuel supply of a boiler, for a building (2) having a boiler (4) and energy accumulation means (4?), in order to ensure a desired indoor temperature during an autonomy period P, this method including the following steps: a) making an estimation of the average outdoor temperature during the autonomy period P, b) determining the consumption of the building (2) in order to ensure said desired indoor temperature, depending on the previous estimation of the average outdoor temperature, c) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required for providing this energy.

Abstract: A trailer-mounted trench burner apparatus comprises a blower source, a carrier pipe supported by roller assemblies on the trailer for movement between a rearward extended position in flow communication with the blower source and a forward retracted position on the trailer, and left and right manifolds pivotally mounted to a rear end of the carrier pipe. The manifolds fold to a storage position extending alongside the carrier pipe and unfold to a usage position extending laterally in opposite direction from the carrier pipe. The manifolds include nozzles for discharging air along an edge of an incineration trench to form an air curtain over the trench and circulate air within the trench. The trailer-mounted trench burner apparatus is designed for fast set-up at, and fast removal from, an incineration site.
