By a special process there is deposit-ed upon the surface a copper coating, and then the gold or silver parts. The unique feature of the entire exhibit is an immense re-volving fan motor rack. A rack with six arms rests on a ball-bearing upon a center post. From extremities of each arm is sus-pended a ceiling fan, and above each arm is a desk fan with the planeof the fan nearly parallel with the arm. With the twelve fans going,the desk fans

From extremities of each arm is sus-pended a ceiling fan, and above each arm is a desk fan with the planeof the fan nearly parallel with the arm. With the twelve fans going,the desk fans cause the entire rack to revolve, which keeps the airof that entire section in circulation. Another interesting exhibit itemis a magnetic separator Used for extracting particles of metal fromcotton before it reaches the gin. The generator and motor exhibit of the Triumph Electric Com-pany covers a wide range of application. Powe- for operating thisexhibit is derived from a Warren synchronous motor driving a 35-kw,. Fig. 4.—Exhibit of Robbins & Myers C- plating can be quickly done. The cleaning and polishing is donewithin glass cases so that the dust and dirt attending such work isentirely absent. In the Robbins & Myers space a very creditable showing is made 220-volt Triumph generator. There is also a Fairbanks-Morse Verti-cal gas engine direct connected to a 754-kw, 220-volt generator, thisset being a good example of the minimum floor space required for ftsmall power station. A motor generator set takes current from theabove source and delivers 10 kw at 500 volts. A number of tools areshown in operations illustrating the method of connected Triumph ^.,;. .t
