Abstract
Abstract A remote meter reading maximum KW demand meter includes a register having an integral pulse initiator. The register drives the pulse initiator in response to maximum demand measuring movement of the meter. In one mode of operation, demand indicating pulses are generated incrementally as the increments of measured KW demand increases. In another mode, the pulse initiator generates a continuous pulse stream responsive to the total maximum KW demand measured during a predetermined billing period when the register is reset by a remotely actuated solenoid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A remote meter reading maximum KW demand meter comprising: a multidial decade register including a gear train coupled to plural pointer shafts for indicating the maximum power demand measured during the predetermined demand interval; a rotating member carried in said register for rotation in response to rotation of said gear train; sensing means responsive to said rotating member rotation for generating pulses representative of a predetermined amount of electrical power demand concurrently indicated by said register wherein said pulses are generated incrementally with increase of measured power demand; and reset means for returning said pointer shafts to an initial state so that the sensing means generates the power demand representing pulses in a continuous series of pulses representative of the total maximum demand measured by the meter upon activation of said reset means.
Claim 2
Dependent Claim
133 words
A remote meter reading maximum KW demand meter comprising: a multidial decade register including a gear train coupled to plural pointer shafts for indicating the maximum power demand measured during the predetermined demand interval; a rotating member carried in said register for rotation in response to rotation of said gear train; sensing means responsive to said rotating member rotation for generating pulses representative of a predetermined amount of electrical power demand concurrently indicated by said register wherein said pulses are generated incrementally with increase of measured power demand; and reset means for returning said pointer shafts to an initial state so that the sensing means generates the power demand representing pulses in a continuous series of pulses representative of the total maximum demand measured by the meter upon activation of said reset means.
Claim 3
Dependent Claim
46 words
The remote meter reading maximum KW demand meter as claimed in claim 1 wherein said reset means includes a solenoid having a plunger coupled to said register gear train for returning said register to a zero start condition when activated by energization from an electrical source.
Claim 4
Dependent Claim
23 words
The remote meter reading maximum KW demand meter as claimed in claim 2 wherein said electrical source is located remotely from said meter.
Claim 5
Dependent Claim
37 words
The remote meter reading maximum KW demand meter as claimed in claim 1 wherein said rotating member is formed by a disc carried on the lowest order pointer shaft of said plural pointer shafts of said register.
Claim 6
Dependent Claim
38 words
The remote meter reading maximum KW demand meter as claimed in claim 4 wherein said sensing means is radiation responsive and said disc includes indicia for optically coupling radiation to said sensing means upon rotation of said disc.
