| 181 | Gas-fired smooth top range | US557032 | 1975-03-10 | US4024839A | 1977-05-24 | Edward A. Reid, Jr.; George W. Myler; James E. Payne |
| A gas cooking range of the smooth top type has four burners positioned under a single plate of heat-resistant glass/ceramic material; and a single igniter and safety control assembly is centrally positioned between the burners. The supply of gas to each of the burners flows through an ignition chamber where it is ignited, and it then flows through a combustion tube to a combustion chamber, where combustion is completed. Some air is mixed with the gas at the fuel supply control valve, and additional air is supplied through the ignition chamber. The burning gas mixture then flows through the combustion tube to the combustion chamber at the entrance of which an additional quantity of air is added to provide the remainder of air necessary for complete combustion. Air is drawn into the system, and the products of combustion are exhausted by a blower positioned at the lower rear of the range so that a negative pressure condition is maintained along the entire path of flow of the fuel gas from the control valve and through the combustion chamber. | ||||||

| An electrically-heated heat-storage oven in which an oven liner of open-fronted box form is fitted externally with upper and lower sole plates which carry electrical heating elements and are backed by layers of refractory material. The refractory layers are built up from cast pieces of refractory material contained within sheet metal trays, the whole assembly being held together by upper and lower horizontal clamping beams connected to one another at their ends by spring-loaded vertical tie rods.

| 184 | Vessel for meltable heat storage masses | US3689738D | 1970-07-13 | US3689738A | 1972-09-05 | LAING NIKOLAUS |
| A tapered vessel having a horizontal metallic base plate and vertically extending deformable plastic side walls contains a meltable crystalline heat storage mass having a greater density in its solid than liquid states whereby the mass is urged against the base plate by gravity. A first electric heater is disposed adjacent the base plate for melting the mass. A second electric heater of less heat output than the first heater extends vertically along a side wall of the vessel to form a connecting channel to relieve excess pressures in the region between the base plate and the bottom of the mass. The vessel is provided with corrugated heat exchange ribs to dissipate the stored heat to the air.

| 185 | Apparatus for heating a storage core of a heat storing furnace | US3581059D | 1966-09-15 | US3581059A | 1971-05-25 | BREITMEYER RICHARD; AMANN KARL |
| A heat storage furnace is provided with a storage core enclosed in a thermally insulated housing. Electric heating elements are provided for heating the core. A main thermal switch responsive to temperatures exteriorly of the housing deenergizes the core heating elements when a predetermined maximum temperature is exceeded. An additional thermally responsive switch is connected in series with the main thermal switch and is arranged to respond to the temperature in the immediate vicinity of an auxiliary heating element connected so as to be energized through the additional thermal switch. The auxiliary heating element is positioned in the housing and is thermally remote from the main thermal switch. The additional thermal switch cyclically opens and closes the circuit to the core heating elements during the charging period before the temperature at the exterior of the housing exceeds the predetermined maximum and the main thermal switch deenergizes the heating elements to terminate the charging period.
