Abstract: ABSTRACT OF THE DISCLOSURE         An installation tool for stringing a tensioned wire between an anchor point and a retaining point, including a sleeve having a slidably mounted pin inside. A tip of the pin holds a loop end of the tensioned wire (such as a coronode in a corotron wire assembly), and protrudes from an end of the sleeve. When the tip holding the loop end of the tensioned wire is placed adjacent to a retaining pin, and the tip is retracted into the sleeve,the loop end of the wire slides onto the retaining pin, where it may rest in a securing notch. A spring may be used to bias the tip of the pin to retract or protrude from the end of the sleeve positioned adjacent to the retaining point. An end of the pin protruding from the sleeve end opposite the retaining point may be used independently or in cooperation with a biasing spring to move the tip of the pin into and out of the sleeve. The sleeve may include gripping areas and or finger loops to permit the user to accurately manipulate the tool. Delicate coronode wires in printers and copiers as well as other spanning wires can be readily installed or replaced using the wire installation tool of the present invention.

Title: Closed loop power controller
Inventor: NELSON ROBERT G
IPC: H03F3/217
Filed: 1994-01-13
Abstract: A power controller includes a closed loop system (10) having a summer (12) to sum an input signal with a derived output signal to produce a difference signal. A comparator (22) compares the difference signal with a reference signal to produce a digital signal representative of the polarity difference between the difference signal and the reference signal. Two switching networks (30) respond to the digital signal to produce high energy outputs representative of the digital signal which are used to reduce the level of the difference signal in a frequency band of interest at the comparator (22). A low pass filter (32) between the high energy outputs and the comparator (22) attenuates high frequency noise. A low-pass filter (32) of at least the third order, connected in the closed loop, enhances the signal to noise ratio. A specific application of the power controller is a power amplifier with the input signal in the audio frequency range.
