Abstract: A water heater having improved efficiency. The water heater includes a tubular member that is mounted in an opening in the side of the tank and extends generally horizontally across the tank. The tubular member defines a combustion chamber and a fuel burner is located within the combustion chamber. The outer end of the tubular member communicates with the atmosphere and air is drawn into the tubular member and mixed with fuel to provide a mixture which is ignited. The waste gases of combustion are discharged from the inner end of the tubular member into a heat exchanger which is located in the tank beneath the tubular member, and the hot waste gases being discharged from the combustion chamber and passing through the heat exchanger transfer heat to the water in the tank. The heat exchanger is connected to a stack and a blower is mounted in the stack downstream of the heat exchanger and serves to draw the waste gases of combustion from the combustion chamber through the heat exchanger to the stack.

Abstract: Needles of a multiple-needle sewing machine are set on its needle holder so that the form which the needle tips form is not in alignment in parallel with the surface of a cloth to be sewn but deviates from the surface in vertical direction.Accordingly, since plural needles will stick into a cloth not all at once but with time lags, the forces exerted on the needles, needle holder, needle rods, etc. may be dispersed. It is also possible that more needles may be used than the conventional multiple-needle sewing machine.

Abstract: A closure (e.g. cover, cap, lid, etc.) having anti-evaporation and spill-resistant features for use on a multi-serving capacity (e.g. 1, 11/2, 2 gallons) container for hot beverages (e.g. coffee, tea, soup) and near-boiling water and incorporating a filling passageway formation through which hot beverages and water may be introduced to fill a container while the closure is in place thereon. A light-weight floating ball normally seats on the upper side of a filling orifice and minimizes evaporation. A heavy-weight (e.g. steel) ball seats against the opposite side of the orifice and prevents the contents from gushing out in the event the container is overturned.
