Abstract: Abstract of the Disclosure In the pack diffusion coating of chromium into the surface of a superalloy, the formation of undesirable oxide inclusion is reduced when the diffusion coating pack contains at least about 3% Ni3Al.  Also the formation of alpha-chromium is reduced when the pack diffusion is carried out in a retort effectively not over five inches in height.  Pack aluminizing in the presence of chromium makes a very effective aluminum-and chromium-containing top coating over platinum plated or platinum coated nickel-base superalloys.  Aluminized nickel can also have its aluminum attacked and at least partially removed with aqueous caustic to leave a very highly active catalytic-surface.  Pack diffusion can also be arranged to simultaneously provide different coatings in different loca-tions by using different pack compositions in those locations. An aluminizing pack containing a large amount of chromium provides a thinner aluminized case than an aluminizing pack containing less chromium, or less chromium and some silicon. A cobalt-chromium pack deposits essentially a chromized case when energized with a chloride, but deposits large amounts of cobalt along with chromium when energized with an iodide. Even more chromium with large amounts of cobalt are deposited when the energizer is a mixture of iodide and chloride. Depletion of diffusible material from workpieces heated in powder-pack can also be readily controlled by adjusting the pack composition, and such depletion from cobalt-base super-alloys very simply provides a surface on which aluminizing produces a highly impact-resistant coating.

Abstract: ABSTRACT OF THE DISCLOSURE             Oil or other combustible material polluting the sea us burned by apparatus having a partly submergible burner equipped with a transducer for generating high frequency acoustic vibrations.  The transducer is surmounted by a velocity transformer designed to concentrate the acoustic vibration at a region of maximum intensity adjacent an upper end of the transformer.  A float arrangement on the burner allows buoyancy to be adjusted so that the upper end of the velocity transformer is disposed a suitable distance above the surface of the water.  An ignition system on the burner projects upwardly above the velocity transformer to ignite a cloud of the oil which is vaporized over the apparatus by energization of the transducer.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical fiber coupler is described for operatively coupling together two or more optical fibers.  Each coupler consists of several biconically tapered fibers.  The biconical sections of each fiber are placed side by side or twisted around one another, and fused together.          The couplers are typically made of optical fibers having a diameter in the range from about 100 to about 300 microns.  The fiber comprises a core of glass having a high index of refraction and cladding of glass with a low index of refraction.  The cladding of each biconical section has been reduced by chemical etching, plasma etching, ion-milling, abrasion or the like, to a thickness not exceeding 25 percent of the core diameter, more preferably less than 10 percent and most preferably from about 5 percent to about 10 percent of the core diameter.  The couplers are of step or graded index optical fiber.  The design can be adapted as multi-port access couplers when more than two fibers are involved.  The reduction of cladding thickness is essential to produce optical fiber couplers with a coupling coefficient of about 40 percent and an average loss of about 10 percent.

Abstract: Abstract The specification discloses a process for producing microcapsules having walls comprising a polyvinyl alcohol type polymer.  The process includes the steps of: (I) dis-persing a water insoluble nucleus material in an aqueous solution of a polyvinyl alcohol type polymer, which solution has a cloud point, (II) causing phase separation and de-position of a concentrated aqueous solution of the polyvinyl alcohol type polymer as a separated phase around the nucleus material by maintaining the temperature of the system at or above the cloud point of the aqueous polyvinyl alcohol type polymer solution, and (III) solidifying the so-formed micro-capsules under such conditions that the separated phase of concentrated aqueous solution of the polyvinyl alcohol type polymer as formed around the nucleus material is subjected to solidification or gelation, but that no solidification or gelation action is exerted upon the diluted aqueous solution of the polyvinyl alcohol type polymer forming a continuous phase.  In this way, microencapsulation can be carried out without the need for the addition of a phase separation medium to the aqueous solution of the polyvinyl alcohol type polymer, which medium tends to increase the porosity of the resulting microcapsules.
