Abstract: BICYCLE  LOCK     ABSTRACT OF THE DISCLOSURE -A locking device for a bicycle or a corresponding                               A locking device for a bicycle or a correspondi ng lockable unit, which comprises a locking member swingable from a releasing position through a wheel of the lockable unit to a locking position and vice versa.  A catch is pro-vided to receive the free end of the locking member and a cylinder lock is attached to the other end of the locking member; and, in order to move the free end of the locking member into the catch and to remove it therefrom, the locking member has to be turned around a longitudinal axis. The swinging movement of the locking member between its locking and releasing position is dependent on the turning position of the locking member so that the swinging movement can be carried out only when the locking member is in a certain turning position.

Abstract: 46,960 GROUND FAULT CIRCUIT INTERRUPTER WITH     GROUNDED NEUTRAL PROTECTION     ABSTRACT OF THE DISCLOSURE         A ground fault circuit interrupter includes a differential current transformer sensing winding supplying input to an integrator which is reset to zero at the end of each half-cycle of AC line current.  A line-to-ground fault current will cause the integrator output to exceed a pre-determined limit value and produce a trip indication.  A saturable neutral transformer supplies a voltage to the neutral line and a reference current proportional to the neutral voltage to a comparator.  The peak value of the reference current is compared to the peak value of the sensing winding output.  A low-resistance neutral-to-ground path causes the sensing winding output to exceed the refer-ence current and a signal to be added to the integrator input, thereby producing a trip indication which energizes an SCR to activate a solenoid.  Means are provided to pro-duce a positive feedback signal to insure a "hard" turn-on of the SCR upon receipt of a trip indication, the feedback means also including capability to "remember" a trip indica-tion at the end of a half-cycle near current zero, and to produce the positive feedback signal at the beginning of the next succeeding half cycle.
