Abstract: ABSTRACT OF THE DISCLOSURE         This invention is an improved filling compound for preventing moisture penetration along the interior of high voltage electric power cables.  Amorphous polypropylene, mixed with carbon where it must be semiconductive, is an extremely good filling compound because of its electrical characteristics and also because of its good flow character-istics when extruding.  When the cable is to be used under condition, where it must withstand temperatures so low that the poolypropylene becomes brittle, it can be blended with polyisobutylene rubber to withstand lower temperatures, but the blend must be kept within limits to prevent loss of the good flow characteristics of the amorphous polypropylene.

Abstract: ABSTRACT OF THE DISCLOSURE A braking system for applying a controllable braking force to the support shaft of a film supply roll, wherein the braking force is proportional to the weight of film remaining upon the supply roll, and wherein the braking force decreases as the supply of film remaining on the supply roll decreases. The system utilizes a pair of brake yokes which are mounted on opposed sides of the frame of an unwind stand, with each brake yoke having a generally "U" configuration, and with the support shaft for the film supply roll being received within the "U" shaped member. The yokes are mounted upon rams which are controllably elevated, and when elevated, a friction pad which lines the inner periphery of the yoke makes contact with the support shaft. The rams are arranged to reciprocatorily raise and lower the yokes for brining the friction material into and out of contact with the support shaft so as to provide controlled braking when required. The braking system of the present invention is employed during periods of temporary shut-down of the apparatus, and is normally not employed to establish a running tension in the film web during normal machine operation.

Abstract: RCA 71,608A        Abstract A peak detector circuit is provided for detecting the maximum excursions of an amplitude varying signal.  The circuit includes a network comprising a capacitor serially coupled to a charging impedance and having a time constant suitable for responding to the maximum excursions of the amplitude varying signal.  A semiconductor means has an input terminal for receiving the amplitude varying signal and an output terminal coupled to the charging impedance for charging the capacitor toward the maximum excursions of the amplitude varying signal.  The semiconductor means exhibits an impedance which is subject to increase with a decrease in current drawn therethrough.  A controllable current sink is responsive to the amplitude varying signal at the input terminal of the semiconductor means and is coupled to the output terminal of the semiconductor means for drawing a component of current through the semiconductor means during the charging of the capacitor which is supplemental to the capacitor charging current drawn therethrough.  The supplemental current component is of a sufficient magnitude to preclude increase of the impedance exhibited by the semiconductor means during the charging of the capacitor beyond a value which is substantially less than the charging impedance.
