<p>NON-CONTACTING RADIO FREQUENCY POWER COUPLER FOR RELATIVE LINEAR MOTION A non-contacting electrical coupler for connecting a linearly movable radio frequency load to a stationary radio frequency power source both having a mean operating wavelength of .lambda.. The coupler comprises a pair of stationary parallel first generally tubular conductor members, each of which have an axially extending opening through the wall thereof. Terminal means are provided near a first end of the first conductor members connecting each of them to opposite sides of the power source. The first conductor members are connected together at a point located a distance substantially equal to odd multiples of .lambda./4 from the first end. A pair of movable second conductor members are disposed substantially coaxially one within each of the first conductor members. Each of the second conductor members have a length substantially equal to .lambda./4 and are axially movable within the first conductor members. The second conductor members are provided with terminal means at one end which connect them to opposite sides of the linearly movable load through the axially extending openings through the first conductor members.</p> |
