The tube milliamperage is also underabsolute control of the operator; simplyby setting the stabilizer to any requiredmilliamperage, from two to thirty, in-sures that exact milliamperage through-out the full period that the tube isbeing energized. By means of the table mounted onthe control stand the operator can de-termine instantly the voltage and read-ing and auto-transformer button re-quired to obtain a given penetrationand milliamperage. The milliamperage chart readily con-veys an idea of the practical design ofthis outfit, with the high tension trans-. 438 former, filament transformer, stabilizer,and tube stand all in one unit. Thiscompactness serves ideally where thephysician is confronted with the prob-lem of limited space. Hospitals will NEW EQUIPMENT find the apparatus applicable in manyways—as it is mounted on casters andis easily moved around to any part ofthe building for use at the bedside orin the operating room. Another Wappler Combination nrHE principal adopted by the Wapp-A ler Electric Company in the con-struction of the component parts of ac-cessory apparatus is proving makes possible the assembling ofvarious combinations for different pur-poses. In applying this principle to the newWappler Junior Horizontal Fluoro-scope of which a description was givenin the August issue of the Journal ofRadiology, it was found very easy toattach a tubestand and a pair of hightension masts to the table. In this waythere was an absolute high tensionproof horizontal fluoroscopic and radio-graphic table. By simply movin
