Abstract: Abstract of the Disclosure:        An apparatus for generating electric pulses is disclosed. The apparatus comprise a gene-rator or oscillator for charging a storage capacitor and a control circuit for controlling the discharge of the capacitor through an out-put or discharge circuit which includes a con-trollable switch device and two output termi-nals or electrodes. In an embodiment, the output circuit also includes a high voltage output pulse transformer.        Whenever a load resistance exists or occurs between the two output electrodes, a particular detector current will flow through the load resistance and through a specific detector or load sensing circuit in the apparatus. This detector current indicating that an external load resistance is present, will automatically start the charging generator which then will operate to charge and recharge the storage capacitor as long as the detector current exists, i.e. 85 long as the external load is present.

Abstract: TRANSISTORIZED ELEVATOR CONTROL BUTTON     ABSTRACT    A switch is closed to generate a short duration pulse.          The pulse activates a semiconductor switch which powers an indicator lamp and generates a D.C. control signal on a single conductor.  A latching unit responds to the D.C. signal on the conductor to latch the switch in the acti-vated state. A reset signal consisting of half wave pulses is transmitted over the conductor.  These pulses charge a capacitor coupled to the switch input to substantially the peak voltage of the half wave pulses, which deactivates the switch.  The capacitor holds a voltage of sufficient level to maintain the switch in the deactivated state until the latch unit is deactivated when transmission of the reset signal stops.
