Abstract: METHOD AND APPARATUS FOR AUTOMATICALLY IDENTIFYING AN INDIVIDUAL CALLING PARTY ON      A MULTIPARTY TELEPHONE LINE  Abstract of the Disclosure After  description of a number of prior art automatic telephone number identification systems and certain problems associated therewith, a new method and apparatus for use in such systems which overcomes the problems of the prior art Is described. In its preferred form, the method includes the steps of applying to the telephone lines at a central office a voltage which has a magnitude sufficient to produce a first predetermined value of loop current In the telephone line. At each party station, the loop current is caused to change between the first predetermined value and a second predetermined value in a manner unique to that party station, with the second predetermined value being smaller than first predetermined value but greater than a value of loop current that would signify to the central office that an on-hook condition exists on the telephone line. At the central office, the loop current change is detected and compared with a plurality of stored loop current changes to provide party station identification, with each stored loop current being unique to each party station. In a preferred embodiment, these steps occur in a predetermined time sequence, with the loop current changes also occurring at predetermined but distinct time intervals, each of which is unique to a party station. The apparatus for practicing this method Includes an automatic party identifier for location at the central office and a subscriber module adapted to be located in circuit with a party station and the telephone line.

Abstract: Abstract of the Disclosure A circuit for sensing and controlling the level of fluid within a reservoir includes a pump for controlling the level of fluid.   The circuit further includes two sub-circuits each including a probe adapted to contact the fluid.   Each sub-circuit further includes an SCR and an oppositely poled diode.          Also included is a relay coupled to the sub-circuits for opera-ting the pump.  The relay is designed to energize the pump only upon submersion of both of the probes.  The circuit is coupled to an AC transformer having, in one embodiment, an off-set center tap such that upon submersion of the first probe the first sub-circuit conducts a first magnitude of energy that is insufficient to pull in the relay but is sufficient to hold in the relay once it is actuated.  In an alternative embodiment, the transformer includes first and second resistors coupled be-tween the relay and the first and second sub-circuits, respec-tively.  The resistors may be of the same or different impedance, such that a different energy level is imparted to the relay when the first probe is in contact with the fluid than when both probes are in contact with the fluid.

Abstract: ABSTRACT OF THE DISCLOSURE          An electric control motor which utilizes a reduction type of gear train to provide output motion to a shaft for positioning devices such as valves, dampers, and other similar equipment is disclosed.  This type of control motor is limited in rotation of the output shaft to less than 360 degrees so that the shaft can be used as a positioning force in numerous control appli-cations.  The total number of angular degrees rotated by the output shaft of the motor is readily adjustable by changing a potentiometer setting.  In order to protect the motor, the linkages, and its load, a limit switch is also provided.  A single stroke adjusting linkage that has a readily accessable location is used to concurrently set the stroke potentiometer and the limit switch so that the output shaft of the control motor is limited in movement to a predetermined number of angular degrees.
