Filed:

Oct 19, 1982

Appl. No.:

6/435251

Inventors:

Taft B. Russell - Edison NJ

Assignee:

Edison Control Corporation - Metuchen NJ

International Classification:

H01R 2500
A44B 1300

US Classification:

24462

Abstract:

A holder for releasably securing a bifurcated core or the like to an electrical power line, the core having two substantially U-shaped portions which are abuttable to form a closed loop that encompasses the power line. An L-shaped boat has at least one leg with an interior configuration that is complementary to one U-shaped portion of the core to receive and hold that one portion. A gantry also having an interior configuration that is complementary to one leg of each U-shaped portion of the core receives both portions and is sufficiently long to permit one leg of each portion to be received while those portions are spaced from each other. The gantry has a guide groove on the exterior thereof for guiding a substantially L-shaped bale which is formed of resilient material and which has one leg that extends over the base of the other portion of the core and another leg which is received by and guided in the groove on the gantry. This other leg of the bale has an end that terminates in a handle which is adapted to be gripped and driven so as to move the portion of the core which is guided in the gantry to abut against the portion which is received in the boat, thereby encompassing the power line. The handle of the bale has a locking ear and the gantry has a locking slot which cooperates with the ear to releasably receive the locking ear, whereby the bale clamps the U-shaped portions of the core together.

Abstract:

Apparatus for electrically communicating between a given location and a variably spaced apart remote location, the locations being connected via electrical conductors. A variable gain amplifier is connected in series between the spaced apart locations for variably amplifying the signals communicated therebetween. A gain control signal that is a function of the separation between the locations is generated and applied to the variable gain amplifier to vary the gain of the amplifier in accordance with the distance between the locations. The gain control signal is proportional to the effective resistance of the electrical conductors extending between the locations. The gain of the amplifier is varied by varying the transconductance of a transconductance amplifier connected in the amplifier feedback circuit in accordance with the gain control signal.
