Abstract: ABSTRACT OF THE DISCLOSURE       A combined solar power generator and water purifier is provided herein.  It includes a hollow globular boiler anchored atop a body of water to be purified.  The globular boiler includes automatically controlled, siphoning, water inlet means disposed adjacent an upper half of the globular boiler, an upwardly directed steam outlet conduit originating from an upper half of the globular boiler, and a refractor lens window disposed within an upper half of the globular boiler.  Controllable means are provided for directing the sun's rays towards the refractor lens window to generate heat to boil water in the boiler.  A primary turbine is disposed at a level above that of the boiler, the turbine being connected to the steam outlet conduit and being driven by steam under pressure from the boiler.  Steam condenser means are connected to the primary turbine for dissipating residual heat in the steam effluent from the turbine and for condensing such steam as substantially pure water.  A reservoir is connected to the condenser means and is disposed at a level which is lower than that of the primary turbine, but at a level which is higher than that of the globular boiler, for receiving such substantially pure water.  A secondary turbine is disposed at a level which is lower than that of the reservoir but which is higher than that of the globular boiler.  The secondary turbine is connected to the reservoir and is driven by water from the reservoir.  Pure water effluent means are provided from the secondary turbine for use wherever pure water is received.          Such solar power generator is thus very energy efficient.

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 produccs a highly impact-resistant coating.

Abstract: A B S T R A C T      To prevent the rupturing, by the expansion of the water upon freezing, of a water-freezing ice-storing reservoir and at the same time release the warmer air after producing the freezing of the water into ice, the interior of the reservoir is surrounded by a duplex wall structure or anti-freeze bar-rier of highly insulating material, such as the expanded pol-ystyrene plastic know commercially as styrofoam, in the form of slabs spaced inward from the tank wall by compression springs so that the inner body of water within the duplex insulating anti-freeze barrier is frozen by freezing the air entering that body through multiple pipes from the outside at-mosphere in winter time while the outer body of water adjac-ent the tank wall of the reservoir but outside the insulating wall thereof is protected from freezing by the insulating ef-fect of the slabs.  At the same time, the air after extending its freezing effect upon the internal body of water is per-mitted to escape through offset or staggered interstices be-tween the individual slabs while freezing of the water between the slabs is prevented by the circuitous path which the es-caping air is forced to follow.  The outer wall of slabs at its upper end is provided with multiple ports through which the escaping air passes into the air space above the water level in the tank and thence to the outside atmosphere through an outlet conduit . The outer wall of slabs is secured at its upper end to the tank ceiling, whereas the inner wall of slabs is divided into multiple tiers of slabs, the slabs of each tier being held together by tie members, such as end-less metal bands, the weights of which offset the buoyancy of the slabs yet permit the slabs of each tier to float as a unit while the escaping air can force its way outward through he interstices between the slabs into and upward through the unfrozen outer body of water into the outer at-mosphere.
