Abstract: A hydraulic cement, such as portland cement, is produced by filling a furnace shell with the desired cement in a powdered condition. By the application of intense heat to the filling a skull is developed that lines an upwardly opening cavity. The heat, which may be supplied by electric arcs, is continued within the skull to maintain a pool of melt that has the same chemical composition as the skull and therefore does not react with the skull. Feed materials are introduced into the melt, and these materials are suitably proportioned to chemically combine within the melt without changing the chemical composition of the melt. The melt is drawn off through a tap hole and cooled to provide the desired cement.

Abstract: A process and compositions for detecting improperly processed areas in heat treated aluminum are disclosed. A solution containing an acid or a base and an oxidizing agent and, if desired, a color enhancing ingredient is applied to an aluminum object to produce a color difference between those areas of the surface of the object which have been properly hardened and the areas resulting from improper heat treatment. The solution can be applied to the aluminum by brushing, swabbing, immersion or spraying. The acid or base in the solution attack the aluminum surface so that the oxidizing agent in the solution can react with the aluminum to produce the aforementioned color differential.

Abstract: A carburetor has a main body provided with a float bowl for holding a volatile liquid fuel, at least one barrel through which combustion air flows, and a fuel supply passage leading from the float bowl to the region of the barrel, all of which is generally conventional. In addition, the carburetor is provided at the entrance to the barrel with a circular discharge nozzle for introducing the fuel into the combustion air. To this end, the nozzle is in communication with the fuel supply passage and is configured to hold a pool of the volatile liquid fuel which flows from the float bowl through the passage and into the nozzle. The nozzle contains apertures which open toward the airstream so that the pressure within the nozzle generally equalizes with that of the airstream. As a consequence, the fuel evaporates quite readily from the pool, and the vaporized fuel escapes into the airstream in sufficient quantity to produce a combustible mixture.

Abstract: A system for converting an audio signal into a three dimensional phased sound that simulates the performance of live music in an acoustically superior music hall includes a signal divider which separates the audio signal into dimensions, that is into high, low, and intermediate frequency components. Each component after being amplified powers a separate loud speaker so that the sound emitted by the three speakers is in phase with the audio signal. In addition, each component is directed through a delay device where it is delayed on the order of 20-300 milliseconds, with the delay for each of the three components being different. The delayed signal components, after being amplified, power separate loud speakers so that the sound which emerges from these speakers is the same as the sound produced at the other speakers, but is slightly out of phase. Moreover, the magnitude of the delay varies between the high, low, and intermediate frequency ranges with the delay being greatest for the high frequency range.
