We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

CH. IV] OXYGEN GENERATOR AND ETHER SATURATOR 113 § 175. For lighting the lamp. — Whatever form of burner is used turn on the illuminating gas first and light it; then turn on the oxygen until the flame is made much smaller, as with hydrogen. For warming and arranging the lime and its distance from the nozzle of the jet see § 158, 162-164. § 176. Putting out the lamp. — Turn off the oxygen first, then the illuminating gas. Remember that oxygen is always on last, and off first. LIME LIGHT WITH OXYGEN GENERATOR AND ETHER SATURATOR § 177. Oxygen generator. — There has recently been perfected a method of preparing sodium peroxide so that it gives off oxygen gas when water is added, somewhat as calcium carbide gives off acetylene gas when put in water. This substance gives about 300 times its volume of oxygen, and serves very well for an oxygen supply when used in a proper generator. § 178. Hydrogen substitute. — The substitute for hydrogen with this outfit is sulfuric ether or gasoline. But ether and gasoline should never be mixed. § 179. Use of the apparatus. — There must be a burner and lime holder as for the oxy-hydrogen lime light. The sodium peroxide (Oxone, oxodium, oxylithe are trade names) is put into the generator and the oxygen gas conducted over to the ether saturator. In the saturator, the stream of oxygen from the generator is divided, one stream of the oxygen going directly to the burner through one tube, F]G 63. PORTABLE OXYGEN and another part going through the ether chamber of the saturator and becoming loaded with ether vapor. This oxygcn GENERATOR AND ETHER SATURATOR.
