then in one nine hundred thirty eight an american inventor put his mind to the problem how could he develop an ultraviolet rays generator which would have none of the disadvantages of the older types one that would make the sun's health giving qualities available at low cost to underprivileged men women and children who lived in homes rarely reached by the sun's rays the inventor frank furedi went to work in a milwaukee basement after several years of intensive experimentation he came out of that basement with a proved theory and an ultraviolet rate generator operating on an entirely new principle activated by radio waves  pure quartz to with no electrodes to deteriorate and burn out simple in principle and operation and automatic timing device so that it could be used safely in the home at a cost which would make it available to people in walks of life but before going to the public with this startling new product mr if you're already gave this lamp a acid test he submitted it to the american medical association which in turn requested an eminent scientist to test the lab here is the scientist summary of his many laboratory tests with some craft ultraviolet lamp produces actinic rays of proper quality and sufficient quantity the health of the american people to carry the electronic discharge through the tube here's the finished part of the lab a burner without electrodes no metal wires to sputter away and coat this precious courts and hold back the vital ultraviolet rays this sealed tube without wires is placed in a field of radio waves and here it is ready to bring its health giving rays into the dark corners of the world but not before each lam gets an exhaustive forty eight hour test under these high frequency radio waves all the waves are there all right you can't see them any more than you can see the ultraviolet rays which are now are pouring through these crystal clear quartz on to emphasize the importance of the courts to an experimental lamp was made up of ordinary glass very little if any of the ultraviolet rays get through to the on the production line skilled hands carefully meticulously bring together the numerous small part these are the hands of people who are mindful of the fact that they are not just  with an unusual pride a performance inspired by an understanding and kindly leaders they assemble and test assemble and test test to make sure that the eventual user will receive the greatest benefits from the vital rays which out of four into hundreds of thousands of home tests of its and now let's see the visual proof that the scientists report this man is giving his face a six minute exposure to sun craft ultraviolet rays next morning he seems rather pleased with the healthy outdoor appearance created by the under the microscope are living organisms on a quartz slide so that the ultraviolet rays can reach them looking through the microscope we can see the effect of the ultraviolet rays on these organisms it is this germ killing property of ultraviolet rays which helps to heal stubborn will and this ability to kill germs is transferred to the bloodstream by the action of the ultraviolet rays on the skin this is a ready aid of blood circulates through the entire body and carries its germicidal power with it that's helping us to resist disease as a result of these beneficial effects of ultraviolet exposure on the blood an interesting medical technique has been developed to speed up this bactericidal action here at great hospital a measured amount of the blood of a patient is by passed through a course container where it is exposed to ultraviolet rays and then research related throughout the body this method has proved especially helpful in fighting virus pneumonia in contrast with this technique of bringing the blood to the ultraviolet rays a quartz applicator has been developed to carry the rays into the body cavit reduce the possibility of infections from operating wounds and to heal incisions more rapidly most of the airborne bacteria in a room can be destroyed without danger of overexposure to any of the rooms  identical meals deficient and calcium and phosphorus so as to induce records but the one that will get the daily ultraviolet exposure from the sun craft lamp during this experiment now compare the two after a week of the calcium deficient diet it's difficult to believe that they are the same age the little fellow is below par in appearance and shows many of the deformities seen and read getting children the ultraviolet ra supplied by the sun craft lamps made up for the deficiency of the diety in the big brother as we saw previously ultraviolet rays activate the sterols in the skin the vitamin d that's is absorbed by the bloodstream and distributed around the entire body the released by them and the stimulates the absorption of calcium and phosphorus which are necessary for the building of strong bones and clamps are so powerful that within four minutes the entire body is bathed in health giving ultraviolet rays these lamps two are equipped with burn out proof from craft quartz two in which the intensity of the ultra violet rays will never lessen no matter how often nor how long they are you in many types of skin diseases due to bacterial infection ultraviolet rays are of great usefulness in the of physical therapy of the american medical association we find the fall of statement it appears to be the general impression in the medical profession that ultraviolet radiation is of great value and dermatology and acne we have seen that many diseases respond to the beneficial effects of ultraviolet rays but prevention of disease is even more important the reflector of the flexible some readily detached so as to follow the motions of a regling m one of the greatest day to day uses in the home for this ultraviolet generator is the prevention of disease by building and maintaining good  the usual peeling of the skin may be avoided by applying a little some craft skin cream before exposing the face to the ultraviolet rays like the food we eat these rays are essential to good mental and bodily health they increase the sense of wellbeing and alertness of mind and act as a tonic in the winter months they are as natural and necessary for the skin as cleanliness sam fresh air outer violet rays improve the health of the skin and a healthy skin is a beautiful skin some crabs tonic effect on the nervous system induces deep restful sleep in safety it is the only ultraviolet rate generator designed for the home which does not get terrier ate with us it continues to send its full quota of beneficial ultraviolet rays through its crystal clear courts year in and year out effectively and safely from its humble beginning in a basement some craft is today sending its beneficence raised to all corners of the work that day more and more people are stepping out of  bringing the vital help giving rays into their home for happier and more healthful
