Excerpt from Transactions of the American Institute of Chemical Engineering, Vol. 10: 1917 During the present war many processes have been developed in this country for the purpose of increasing our supply of needful materials. Many of these processes have been developed into successful commercial form. Arts have been established. I think every one who has been instrumental in developing these arts, and many others also have asked themselves what is to become of these arts when the war - is over. Are these arts, due to foreign competition, to become extinct and lost as it were, or will they be able to stand on their own feet in face of that com petition? The answers to these questions will vary according to the arts. Some have, undoubtedly, become firmly established and will withstand foreign competition. Others, undoubtedly, will tend to become lost arts, and this tendency should be considered as most unfortunate. N ow is the time to study this question and to be prepared to meet it when the war is over; meet it if need be by allowing the arts to perish, or, if it is more desirable to main tain the arts, by appropriate methods of procedure.

Excerpt from Transactions of the American Institute of Chemical Engineering, Vol. 1 of 12 The Snyder or any other direct arc furnace is applicable only to true bronzes or other alloys low in zinc, 5% zinc being the probable limit. It is entirely impractical for use on alloys high in zinc. The only installation used for copper alloys is used on leaded bearing bronze, the new lead being added in the ladle. Much lead is volatilized from the scrap in the charge, and much fume results, giving bad working conditions. The installation of Snyder furnaces has a very poor power factor, though this is not necessary in a direct arc furnace.
