Medal for the discoverer of “Permutit”.

The Franklin Institute awarded the Elliott Cresson Gold Medal for 1916 to Dr Robert Gans, of Pankow, near Berlin, Germany, for the discovery of “Permutit”, a substance which has taken an important place in domestic life. and industrial world. This medal and diploma, under Elliott Cresson’s Deed of Trust of February 18, 1848, to the City of Philadelphia, is awarded annually by the Franklin Institute on the recommendation of its Committee on Science and the Arts, “for original discovery or research. add to the sum of human knowledge regardless of business value; or products embodying substantial elements of leadership in their respective classes, or unusual skills or manufacturing perfection. In December 1915, the Committee – after examining the field of scientific activity – recommended that the prize be awarded to Dr Gans. The Institute then, in accordance with its usual procedure, issued notices of objection over a period of approximately three months and finally issued the formal award to Dr. Gans. The medal and diploma were therefore sent to officials at the Permutit Company, New York, to be forwarded to Dr. Gans when circumstances permit. “Permutit”, the technical name applied to Dr. Gans’ discovery, is a substance resulting from the fusion of alumina, silica and an alkali carbonate. Its property is to exchange one of its constituents for other elements brought into solution in the water which passes through it. This exchange is automatic and continuous. And after the “Permutit” runs out under a full item swap, it can be regenerated by going through it another solution that restores the original item. While “Permutit” can be prepared in a number of combinations to extract various elements from solution, its main use in the industrial and domestic world is for water softening. Hard water is water containing varying proportions of lime and magnesium. In the textile industries, in dyeing establishments, in laundries, in paper mills, in the revenue industry and in many other fields, hard water seriously interferes with operations, affects product quality and adversely affects efficiency. In the household sector, hard water prevents perfect washing, interferes with the proper preparation of food and has a harmful effect on the skin and hair. In power plants, the hardening elements in water are the sludge and scale forming elements that coat the inside of boilers, incur significant repair and maintenance costs and require extravagant fuel consumption. That the “Permutit” is an industrial fact and not a mere experimental laboratory process is proven by the remarkable extent to which it has established itself in recent years. The Permutit Company, 30 East 42nd Street, New York City, controls the commercial exploitation of this product; and it reports over 500 industrial factories already established in the United States alone, alongside hundreds more in Germany, France and England. The fact that “Permutit” equipment delivers an infallible supply of absolutely fresh water has brought about almost revolutionary changes in some areas.

Electric water sterilizer.

Large apartment buildings and hotels find it profitable to maintain good water purification systems. Bottling factories that set up carbonated drinks spend a lot of money on water purification, so that the pure fruit juices and extracts from their finished drinks don’t get spoiled. Modern manufacturing plants and department stores install purification systems. There are many methods of purifying water. Some use filters, others chemicals, while still others heat the water to kill bacteria and germs. One method is Standard Electric Sterilizer No. 2 from Electric Water Sterilizer Co., Scottdale, Pa. It has long been known that electricity breaks down water into its elements: hydrogen and oxygen. As a result, it has been discovered that when the water breaks down, a large part of the animal and plant matter present in the water is rendered inert. The oxygen released is in such a form that it will help destroy the lower forms of animal and plant life. At the same time the plates, which are used to transport the current in the water, reject an insoluble compound which accumulates in mass around the vegetable and organic matter and makes it possible to filter everything very easily out of the water by filters. mechanical. The illustrated sterilizer consists of four essential parts, the electrode box, the coagulation chamber, the filter beds and the automatic hydraulic motor and switch. The water to be purified just enters the electrode box. This box is made up of a number of metal plates containing slits through which the water passes. There is low current consumption because the resistance of the water is actually used to treat the water. After leaving the electrode box, the water flows into the coagulation chamber where germs and bacteria come together. These are filtered when the water passes through two filter cylinders. The water comes from the second cylinder ready for use. The sides of the cylinder are covered with a layer of baked quartz to prevent water from following what could be the smooth sides of the cylinder. Whenever water is drawn from a faucet connected to the machine, the hydraulic motor automatically turns off the electrical switch so that the power is only used when the water is drawn. When the water is cut off, the hydraulic motor stops and automatically cuts off the electrical circuit. Electric current is isolated from the filter cylinder and the water supply line by long insulating tubes, inserted into the metal piping under the electrode box, and the electrode box itself rests on four large porcelain knobs, thus preventing any current earthing. In installations where alternating current is the only source of energy available, a means of changing it to direct current is recommended, since in the latter form the current consumption is less. The illustration shows the electric water sterilizer equipped with a Westinghouse generator set and control panel. The assembly is used to change the AC power of the DC power system for use in water treatment. It is connected to an automatic switch controlled by the water flow, so that it only works while water is being sucked through the machine.
