Estimation of the Composition of Three Component Liquid Mixtures

While carrying out research on the extraction of oil from soybeans using mixtures of various solvents, it was quite often necessary to know the composition of a mixture of liquids containing three components. A search of the literature for ways of obtaining the composition of such mixtures by the use of physical constants revealed a very convenient method employing a combination of density and refractive index. Before this method can be used, however, solutions covering the entire ternary system must be made up accurately, their refractive indices and densities taken and plotted in such a manner that the composition of solutions of constant refractive index and solutions of constant specific gravity can be determined. Finally a triangular diagram must be constructed showing the lines of constant refractive index and constant specific gravity as related to the composition (1, 2)

The Commercial Preparation of Oxygen from Lime and Chlorine

The reaction of chlorine on a suspension of lime in the presence of suitable catalysts, such as nickel, cobalt and iron salts, has been studied. It was found that the optimum temperature is 94° C.; that the greatest unit efficiency of the catalyst, nickel nitrate, is obtained at a concentration of.02 g. per 100 c.c; that the rate of generation of oxygen is almost directly proportional to the rate of flow of the chlorine and that nickel and cobalt salts are distinctly superior to all other catalysts which were used. In addition it has been found that the catalyst is not easily poisoned, and may be used throughout a number of runs

Modification of Blood by Zeolites for Transfusion Purposes

Richard Lower made the first blood transfusion in 1665, but the wide use of the technique in medicine is quite recent. One of the difficulties lay in the coagulation of the blood during the transfer. Accordingly, the blood is generally treated with sodium citrate to prevent this. It is known that calcium in the blood has something to do with the coagulation and probably with the agglutination. It was decided to study blood from which the calcium had been removed. To remove the calcium we adopted the principle used in removing calcium from hard water, that is, passing· it over a zeolite. Blood is viscous-especially coagulated blood-hence it was necessary to use suction to force it through the tube filled with zeolite. The tube was attached to a filter flask which in turn was attached to a filter pump. In this way the blood was passed through the zeolite bed successfully

Measured performance of the new University of California gamma ray telescope

The design of the new medium energy balloon-borne gamma ray telescope is discussed. This telescope is sensitive to 1-30 MeV gamma rays. The results of the initial calibration are described. The position and energy resolutions of 32 plastic and NaI(Tl) scintillator bars, each 100 cm long are discussed. The telescope's measured angular and energy resolutions as a function of incident angle are compared with detailed Monte Carlo calculations at 1.37, 2.75 and 6.13 MeV. The expected resolutions are 5 deg FHWM and 8% at 2.75 MeV. The expected area-efficiency is 250 cm

Solvent Extraction of Soybean Oil by Mixtures of Trichloroethylene and Ethyl Alcohol

Various solvents have been used for extracting vegetable oils such as soybean oil. Certain petroleum fractions are widely used commercially. They have the advantage of low cost, but the disadvantage of being highly flammable and their vapors being explosive in a wide range of mixture with air. Certain of the chlorinated hydrocarbons are excellent solvents but have had only limited use because of high cost and lack of suitable processing methods and equipment. Process and equipment for the use of trichloroethylene, one of these chlorinated hydrocarbons, have been developed in Engineering Experiment Station Laboratory, Iowa State College. Trichloroethylene is a colorless liquid boiling at 86.7°C. with a specific gravity of 1.46 at 25°C. It is an excellent solvent for soybean oil, is non-flammable, and of a toxicity of the order of the usual petroleum fractions. Various alcohols such as ethanol and methanol have had limited application

The Production of Chloropicrin as Needed from Dry Mixtures of Picric Acid and Bleaching Powder

Chloropicrin or trichloromethane is a colorless liquid boiling at l 12°C and having a specific gravity of 1.69. It was first prepared by Stenhouse from picric acid and bleaching powder. Its first use was in chemical warfare by the Allied troops in 1918. It was prepared in large quantities at Edgewood Arsenal during the World War, by the method developed and patented by the senior author. Picric acid, hydrated lime, and water were mixed to form a calcium picrate suspension. This suspension together with a suspension of bleaching powder and water was run into a still. The chloropicrin was steam-distilled off

A Method of Maintaining the Proper Copper Concentration in the Treatment of Water

When water is impounded in a reservoir it usually becomes infested with algae. \u27While not poisonous many of these algae impart disagreeable odors or tastes to the water, making it undesirable for drinking purposes. When the Croton dam was built as a part of the New York City water supply system, the water in the reservoir behind it became contaminated with algae. Upon the recommendation of Karl F. Kellerman, whose father, Professor Kellerman of Ohio State University, first noted the toxic effect of copper on algae, the water was treated with copper sulfate. This was effective and is being used quite generally in water reservoirs. The usual procedure is to place crystalline copper sulfate in a burlap bag attached by a rope to a boat and draw it back and forth slowly through the water. It must be done at the proper speed to produce the correct concentration necessary to kill the algae without killing the fish or making the water impotable

Possible Uses of Waste Chlorine

The demand for electrolytic caustic has glutted the chlorine market. Studies are underway looking towards the utilization of chlorine. It has been found that by passing chlorine through lime covered with water in the presence of iron or manganese as a catalyst that practically quantitative yields of oxygen are evolved. The method is believed to be commercially applicable for producing oxygen. It is also a superior method for laboratory demonstration and use

DeepPrivacy: A Generative Adversarial Network for Face Anonymization

We propose a novel architecture which is able to automatically anonymize faces in images while retaining the original data distribution. We ensure total anonymization of all faces in an image by generating images exclusively on privacy-safe information. Our model is based on a conditional generative adversarial network, generating images considering the original pose and image background. The conditional information enables us to generate highly realistic faces with a seamless transition between the generated face and the existing background. Furthermore, we introduce a diverse dataset of human faces, including unconventional poses, occluded faces, and a vast variability in backgrounds. Finally, we present experimental results reflecting the capability of our model to anonymize images while preserving the data distribution, making the data suitable for further training of deep learning models. As far as we know, no other solution has been proposed that guarantees the anonymization of faces while generating realistic images.Comment: Accepted to ISVC 201
