Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
An amplifier structure adapted for connection to remote units, comprising a casing having a front panel provided with control means, a rear panel, a pair of side panels extending therebetween, a top portion, a cover for the top portion, an elongated depressed area having upstanding walls extending to the top portion, one of said walls being closer to said front panel and including connector means which extend parallel to said front panel, said top portion further including a front area lying in one plane and a rear area of greater longitudinal extent lying in another plane beneath said front area and means for supporting the cover at least above the rear area to permit conductors to extend thereacross and to communicate with said connector means in said depressed area.
Claim 2
Dependent Claim
129 words
