News from the Instrument Shop 



{Being the fourth, and last, of a series of advertisements by Eimer & Amend, setting forth their 



chief attainments during the war.) 

 The uncommon achievements of our instrument shop during the past few years readily fall into 

 three groups: 



FIRSTLY, the experimental work on} variousyjapparatus]for',%ise [of fjhe 

 American and Allied Military Forces. 



SECONDLY, the rebuilding and refinishing of imported apparatus — some 

 pieces could not be replaced on account of the lack of essential parts, while 

 other pieces possessed sufficient salvage value to warrant reclamatioru* 



THIRDLY, the building of complete instruments and apparatus to replace 

 those of foreign manufacture. This third class, as well as the second, loas 

 carried to the point only where it would not conflict mth the more impor- 

 tant business of helping to win the war. 



WORK ORDERED by the Government and done directly for it was perhaps the most interest- 

 ing. Our files for 1917 and 1918 contain countless orders from the Gas Defense, Gas 

 Offense, the Army Medical Schools, the Aviation Fields, the Medical Supply Depots, etc., 

 for apparatus and devices of many special kinds " as per instruction to the Machine Shop." 

 This labor was noi limited to experimental work, but quantity production was also effected, 

 as evidenced by the fact that thousands of gas detectors used by the American Army on 

 the fields of France bore our trademark. 



THE SUGAR industry was greatly inconvenienced by the inability to procure French or Ger- 

 man polariscopes. When the consequences had assumed a serious aspect, we undertook 

 to remodel a Schmidt & Haensch instrument, including repolishing, cementing and re- 

 pairing of the prisms. The results was so highly pleasing to our customer that we secured 

 a continuous flow of orders of this kind from ail over the sugar-producing sections of the 

 United States, Cuba, and Porto Rico. To the best of our knowledge, all the polariscope 

 observation tubes produced in the world during the past two years {except those, if any, 

 turned out by our enemies) were made by us. 



AMONG precision instruments of similar class which we have taken the time to dismantle and 

 remodel, let us mention Wanner pyrometers and Zeiss microscopes, including their 

 objectives. 



WE HAVE manufactured COMPLETELY Beckmann boiling point and freezing point apparatus; 

 Duboscq colorimeters, quite like the original French, and, we think, better; Juerst ebullio- 

 scopes, to replace the Salleron; and also a number of other intricate physical apparatus. 



IN ADDITION to'these, we have maintained and increased our normal output of such well 

 known specialties as the three types of Young's specific gravity instruments (two styles 

 embodying displacement plummets of incomparable accuracy) excelling in sensibility the 

 highest class of analytical balance; Kimley Electro-Analgsis apparatus; Gramercy Stirrers, 

 andjnany others. 



THE CAPABILITIES and the facilities that raised this shop and its' work above others of its 

 kind are now available for the solution of problems like in nature to those indicated by 

 the foregoing resume.
