Abstract: HAZARDOUS VOLTAGE PROTECTOR FOR TELEPHONE LINE Abstract of the Disclosure Telephone terminal equipments connected to the network through the device described herein are prevented from applying potentially human-hazardous voltages or currents to the network.  The device includes a pair of bifilar relay coils, one in each connection to the central office.  These operate an associated relay contact only when an unbalanced voltage or current condition occurs on the customer leads.  A circuit path is thus completed to operate a second relay, which opens the connection between the customer terminal leads and the network leads; and establishes a path to ground through its own coils for the current from the unbalanced source.  Means are included for assuring that the fraction of hazardous voltage appearing across the second relay remains essentially constant in the frequency range of 17 to 60 hertz.  Only removal of the unbalanced current can release the relay and restore the network connection.

Abstract: CIRCUIT BREAKER MOTOR AND HANDLE CLUTCH              ABSTRACT OF THE DISCLOSURE         A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position.  The movable contact is mounted to a contact holder which engages one link in a toggle means.  The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever.  A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate.  The fol-lower plate has a drive pawl attached thereto, with the drive pawl being disposed adjacent the drive pin.  Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions.          The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly.  The outward move-ment of the cam roller causes rotation of the follower plate, resulting in charging of the spring means.  When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position.          Upon moving into toggle position, the toggle means moves the contact holder and movable contact into closed position.          Also included are releasable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively.     Means for rotating the drive shaft include a handle secured to the drive shaft and a motor operator having a rotatable output shaft which is capable of engaging the drive shaft and which can be easily installed.  A motor and handle clutch is used to prevent rotation of the handle upon rotation of the motor, and to prevent rotation of the motor upon rotation of the handle.

Abstract: Abstract of the Disclosure A digital signalling receiver translates pulse code modulated (PCM) tone signalling into a signal format compatible with a controller in an associated time division multiplex (TDM) telephone switching facility.  In the receiver, steering signals are generated in synchronism with the operation of the switching facility to direct the operation of a time shared filter.  The filter performs a plurality of filter functions with a series of PCM signals received from the TDM switching facility and generates therefrom series of filter signals relative each of the filter functions.  A translator identifies two filter signals having larger amplitudes than the others and if the two signals persist substantially uninterrupted (a) through a predetermined period of time, (b) within a predetermined relative amplitude range and (c) one of the two signals having at least a predetermined signal to noise ratio relative another filter signal corresponding to an allpass filter function, the translator indicates the receipt of multifrequency signalling by generating the appropriate signals in the required signal format.                             - i -
