Abstract: An in situ thermal system is disclosed for enhanced oil recovery and the like from a subterranean formation. The system pressurizes the formation with water whereupon the entire formation is heated to relatively high temperatures in the absence of gas formation to significantly decrease the viscosity of substantially all the crude in the formation and permit recovery thereof.

Abstract: A burner is described which comprises a cylindrical body, orifices for the exit of the mixture, the orifices being arranged in groups of slits and being of minimum width and moderate length, set side by side in parallel sub-groups, so as to give rise to fan-shaped flames with a single flame front corresponding to each group. In this manner the noise of the burner is reduced and a great stability of the flame is achieved which makes the flame itself regular. This fact produces advantages both as to uniformity of operation and efficiency of the burner. According to one embodiment of the invention, the first plate of the burner is covered by a second plate which is provided with orifices through which the flames coming from the groups of slits pass.

Abstract: 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.

Abstract: A burner construction having a tubular member provided with an inlet for receiving fuel from the supply thereof and having an outlet for issuing and burning a main flow of the received fuel to produce a main flame at the outlet. A deflector plate is carried by the tubular member adjacent the outlet for directing some of the received fuel substantially transverse of the tubular member to create an ignition flame substantially transverse to the tubular member for igniting the main flow of fuel at the outlet to create the main flame. Thus, a series of such burner constructions can be disposed in a side-by-side relation and one pilot burner can be utilized to ignite the same in serial relation through the ignitor flame plates thereof.
