摘要： Carbonaceous deposition on the surface of steel cracker tubes in chemical plant for the thermal cracking of hydrocarbons is a serious problem. It is met, in the invention, by providing the surface with a refractory oxide coating by contacting the surface with a sol comprising an aqueous dispersion of substantially unaggregated primary particles, the sol being capable of conversion to a gel the bulk density of which being at least 40% of the theoretical density of the refractory oxide when measured at ambient temperature and the gel being convertible to the refractory material, converting the sol to the gel, and firing.

摘要： The invention is concerned with providing substrates with coatings obtainable from sols, for example to protect the substrate (such as in nuclear reactors or hydrocarbon cracking plant) or to provide a carrier for catalytically active material.Hitherto, coatings obtained from sols have had a high porosity and high surface area so that they have not been entirely satisfactory for the above applications.In the invention, dense, low-porosity coatings are provided by contacting the substrate with a sol of refractory material (e.g. CeO.sub.2 or SiO.sub.2) convertible to a gel of density at least 40% of the theoretical density of the refractory material, and converting the sol to the gel. Optionally, the gel may be converted to a ceramic coating by firing.

摘要： A method of applying a gas shielded tungsten arc welding process in a deep, narrow groove joint wherein the shield gas is directed to the weld puddle through an elongated gas nozzle 14 which surrounds a substantial length of the welding electrode and is sized to extend into the groove. The improvement including incrementally increasing the width (20) of the nozzle to correspond to increases in the width of the groove at preselected increases in the width of the groove as the nozzle is withdrawn from the groove during successive weld passes. The preselected elevations and nozzle widths are chosen so that the desired gas shield area does not substantially exceed 1.25 times the nozzle width.

摘要： An improved automated acousto-optic analyzer system includes an acousto-optic tunable filter which is coupled with a source of radiation to produce pulsed light at predetermined wavelengths. This light is transmitted through a gas stack containing gases to be analyzed, to a distant detector. The configuration of the acousto-optic tunable filter, radiation source on one side of an environment of interest and a detector on the opposite side of an environment of interest produces spatial separation of the tuned, diffracted light from the undiffracted broad spectrum of the light source at the detector. This configuration eliminates the need for polarizers in the system. It also combines the tuning function of the AOTF with a chopping function, allowing extraneous radiation to be discriminated against. Thus the improved configuration of the disclosed invention permits effective operation of the gas analysis system in a gas stack characterized by extremely high ambient temperatures.
