Abstract: Apparatus for applying plural components to a work surface. One embodiment contemplates the application of a primarily resinous solution having an operative amount of catalyst admixed therewith. Another embodiment contemplates the application of an epoxy comprising substantially equal parts of resin and catalyst. The apparatus segregates the operating fluid from the components being pumped so that an epoxy may follow or be preceded by an application of polyester resin, in the absence of apparatus cleaning or flushing between applications.

Abstract: This invention provides a burner head that may be used for the discharge of a mixture of steam and oil. Steam bores 10 penetrate the head from one end to the other. Oil ducts 11 lead to each bore 10 from one end of the head. One or more further ducts 13 lead from the rear end of the head to a chamber 2,20 formed at the front end of the head and additional oil ducts 12 lead back from the chamber to discharge one into each of the bores 10. The two ducts 11 and 12 that discharge into any bore are directed towards each other.

Abstract: A process and apparatus for the combustion of liquid fuel provides an extremely intense blue/violet flame having a temperature in excess of 3000.degree. F. with combustion under near perfect stoichiometric conditions without the formation of soot. The liquid fuel is atomized and mixed with air within a nozzle and enters a flame tube surrounding the nozzle as a conical stream where it is further atomized by jets of air directed to converge on the stream and mixed with secondary combustion air to obtain the desired combustion mixture. Yet further atomization of the liquid fuel-air mixtures within the flame tube can be obtained as a consequence of at least partial vaporization of the liquid fuel therein through the heat of the flame tube. An advantageous relationship exists between the size, angle and point of convergence of the air jets with the atomized conical stream, the flame tube diameter and length and the location of the nozzle therein and the fuel feed.

Abstract: Apparatus is disclosed for the carrying out of gaseous phase reactions, illustrated by way of example by the preparation of sulphur hexafluoride of high purity, starting from elemental fluorine and sulphur, both in gaseous phase. One of the gaseous reactants, e.g., the fluorine, is fed into a reaction chamber through inlets in a metal plate, maintained at between 30.degree. and 70.degree. C. while the other, e.g., sulphur in gaseous phase, is fed in through the nozzle of a burner, e.g., by regulating a current of an inert gas which is saturated with sulphur by passing same through a zone containing molten sulphur at a temperature between 250.degree. and 500.degree. C., and subsequently superheating the inert gas thus saturated with sulphur to a temperature between 300.degree. and 550.degree. C.

Abstract: Spraying of materials, which prior to the spraying operation have been mixed from two airborn material flows in a spray nozzle, results in a high wastage rate. It has now been found that this wastage can be highly reduced, if in an appropriate apparatus one of the material flows is restricted, whereas the other material flow is allowed to expand when introduced axially into and mainly in the center of the first restricted flow of material, the second expanding flow of material thereby further being used to create by ejector effect a suction acting upon the restricted flow of material.

Abstract: A system for delivering a siliceous matrix material and selected dopants to an oxidizing reaction flame or the like. Each constituent is maintained in liquified form and transferred by means of an individually controlled metering pump to a nebulizing stage then passed to a burner or the like from which the materials are converted into appropriate soots. The soots are then applied to a starting member which is subsequently subjected to heat to fuse it into a drawing blank.
