The grid is a perforated plate or mesh of fine wire through the openings of which the electrons must puss in their journey from the filament to the piste. Fig. VII is a diagrunmiuih'iil sketch e of thq circuits of a vacuum tube and la Identically tin same ua the sketch in Fig. Ill for t vacuum tule with the ad dltlou of the grid circuit The battery in the grid circuit la called the battery. As a start let us suppose that C" battery voltage ia sera. The operation of the tulie would then be exactly like that of a tulie. Just as though there were no grid. Like a tulie when the filament C-is brought to lncundesceiice by the A" battery a steady at ream of electrons will lie given off, which will lie drawn over to the plate K. Hate K is maintained at a positive potential with reiqieet to the filament by the II Iwttery. Now If the grid Is made positive with respect to the filament, it is possible to accelerate the flow of flie electron stream from the filuiueut to the plate; If the grid ia made negative with resiieet to the filament, the flow of the electron streutu from the filament to the plate will he retarded. Or in other words, by making the grid positive or negative with retqiect to the filament. It is possible to Increase or counteract the space charge.

This law contains two provisions: first, it allows tensions to all sailors and marines with the above service record who were honorably discharged and who are now over sixty-tw- o years of age; second, it allows tension to those who are at present materially disabled froril earn ing thir living by manual labor from disease, if the disability be not the result of their own misconduct. Such disability must be permanent but nued not be total. It need not be the result of military service. The soldier does not have to be sixty-tw- o years old to claim on disability. The amount of 'pension depends upon the degree of disability and ranges from twelve to thirty dollars a month. Widows of veterans are also allowed pensions. Hew Management run! rs, BMf.

Any device which will pass electricity In one direction and will wholly or partially obstruct the flow lu the opposite direction la termed s rectifier, because when connected in the path of an alternating current it will supof each cycle and therepress one-hafore the circuit will be traversed by pulsating direct current. A rectifier also Is said to possess unidirectional conductivity, meaning, of course, that it will conduct electricity in one direction only. Its ability to rectify currents of extremely high frequency determines its application in radio. Due to its ability to rectify high frequency alternating currents the (filament and plate) vacuum tube can be used In a radio receiver as a detector. Fig. VI Is a simple radio receiving circuit employing this type of vacuum tube In place of a crystal detector. Dr. J. A Fleming of London, England, was the first to use s tube of the type Just described ss a medium of rectifying high frequency radio currents. Fleming called bis product a valve because It would let current flow In one direction but not In the other direction. The Fleming valve as s forerunner of the vseu- lf and Snnnyside.
