Abstract: A train loading system for loading material onto cars of a train is disclosed. The system comprises a material bin arranged to receive material to be loaded onto the train, a closure device arranged to facilitate control by an operator of the amount of material loaded into each car from the material bin, and a car mass estimator arranged to estimate the mass of material loaded into each car. The system also comprises a display arranged to communicate to the operator the estimated mass of material loaded into each car. A corresponding method is also disclosed.

Abstract: An instantaneous gas water heater comprising a control panel, a heat transfer section, and a blower section. The control panel includes an electronic controller, a gas solenoid valve, and a means to prove the operation of a blower. The heat transfer section comprises an inner jacket enclosing a combustion chamber and an outer jacket enclosing the inner jacket. The combustion chamber contains an ignition means, a combustion means, and a baffle. In the preferred embodiment the combustion means was a powered burner comprising a venturi tube with venturi tube holes, and a woven ceramic fabric mantle containing the venturi tube. The baffle is made up of a spine, consecutive ribs attached to the spine, spine holes in the spine disposed between the ribs, and rib holes in the ribs, the rib holes being disposed in consecutive ribs on alternating sides of the spine. The blower section includes a blower communicating with the combustion chamber through a gas/air mixing chamber.

Abstract: Heating apparatus for producing both central heat and tap water, specifically adapted for trailers and similar mobile houses with small spaces is provided. The heat source is a burner combusting LP-gas. Heat cartridges for electric heating optionally provide a supplemental heat source. The burner operates in a cylindrical space consisting of a burner tube with a plurality radial flanges which conduct heat energy outwards to a ring-shaped space delimited by a second tube. A heat medium for central heating is contained in the ring-shaped space. A tube-shaped vessel for tap water surrounds the ring-shaped space. The tap water vessel, the second tube and the burner tube are respectively positioned inside each other.
