Abstract
Abstract An apparatus for reading at a central station a multidial meter such as a utility meter or similar device located at a remote station by transmitting coded pulses representative of the digits shown on the meter over a conventional telephone line and decoding the pulses at a central station. To obtain a reading of any specific customer''s meter, a master translator unit at the central station sends out a signal through the telephone system to a slave translator unit which is electromechanically connected to the customer''s meter in such manner that a series of binary coded drums in the slave unit store coded information representing the amount of utility service used by the customer. The slave unit is designed to individually scan each bit of information stored in the coded drums and send a sequence of pulses through the telephone line with each pulse being representative of one bit of information. Upon receiving each pulse, the master translator unit sends it through a certain predetermined circuit to the proper location in a decoder which converts the information either into readable digits or into an output for a computer which compares the output with stored information on previous meter readings for computing the customer''s bill.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
251 words
An apparatus for reading a customer''s utility meter at a remote station over a telephone line from a central station comprising: A. a master translator unit located at a central station and connected to a telephone system; B. a slave translator unit located at a remote station and connected to a meter to be read and to a telephone line which is normally connected to the telephone of the customer whose meter is to be read and to the telephone system serving the master translator; C. a counter and storage unit in the slave unit actuated by a single rotary member of the customer''s meter to count the number of units of the item being metered at the same time that each unit is registered on the meter and store the count results as individual bits of coded information retained in the slave unit until a readout is called for by the master unit; D. a slave readout selector switch in the slave unit which determines the readout sequence of the bits of coded information stored in the counter and storage unit; E. a multisection decoder in the master translator unit; F. a master readout selector switch in the master translator unit synchronized with the slave readout selector for directing each bit of coded information to the proper location in the decoder section; and G. a signal generator to provide signals to the slave translator unit to perform a readout of the coded information stored in the cOunter and storage unit.
Claim 2
Independent Claim
251 words
An apparatus for reading a customer''s utility meter at a remote station over a telephone line from a central station comprising: A. a master translator unit located at a central station and connected to a telephone system; B. a slave translator unit located at a remote station and connected to a meter to be read and to a telephone line which is normally connected to the telephone of the customer whose meter is to be read and to the telephone system serving the master translator; C. a counter and storage unit in the slave unit actuated by a single rotary member of the customer''s meter to count the number of units of the item being metered at the same time that each unit is registered on the meter and store the count results as individual bits of coded information retained in the slave unit until a readout is called for by the master unit; D. a slave readout selector switch in the slave unit which determines the readout sequence of the bits of coded information stored in the counter and storage unit; E. a multisection decoder in the master translator unit; F. a master readout selector switch in the master translator unit synchronized with the slave readout selector for directing each bit of coded information to the proper location in the decoder section; and G. a signal generator to provide signals to the slave translator unit to perform a readout of the coded information stored in the cOunter and storage unit.
Claim 3
Dependent Claim
139 words
A meter reading apparatus as claimed in claim 1 wherein the counter and storage unit comprises a plurality of rotary coded members having electrical contact strips arranged in a coded pattern thereon to make or break a plurality of electrical circuits in the counter and storage unit, depending upon the relative position of said rotary coded members, each of the rotary coded members corresponding to one of the visual dials on the meter to be read and the rotational position of each rotary coded member at any given time being related to the amount shown on the meter dial to which it corresponds, one of the rotary coded members being actuated in response to one of the rotary shafts in the meter and each of the other rotary coded members being actuated by the preceding adjacent rotary coded member.
Claim 4
Dependent Claim
21 words
A meter reading apparatus as claimed in claim 2 wherein the code pattern of the contact strips is a binary code.
Claim 5
Dependent Claim
44 words
A meter reading apparatus as claimed in claim 2 wherein at least one of the rotary coded members of the counter and storage unit are rotated a fractional part of one revolution by a solenoid each time one unit of the utility is used.
Claim 6
Dependent Claim
44 words
A meter reading apparatus as claimed in claim 4 wherein the solenoid which advances the rotary coded members is energized by the closing of a counter switch which is closed by a cam attached to one of the rotary shafts in the customer''s meter.
Claim 7
Dependent Claim
44 words
A meter reading apparatus as claimed in claim 5 wherein the rotary coded members are cylindrical drums rotatably mounted in axial alignment on a shaft with each successive drum rotating a fraction of a revolution each time the preceding drum rotates one complete revolution.
Claim 8
Dependent Claim
