Abstract
Abstract A tape recorded system especially advantageous for reproducing a melody played on bells and a striking of the hour at the appropriate interval makes use of clock controlled electronic logic operable at the conclusion of the melody. A pulse generated by the bell sound on the tape trips the mechanism to sound the proper hour and by providing sufficient time for decay produces a realistic bell tone.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
208 words
A musical tape play system for the reproduction of bell tones comprising a sound tape length having electronically reproduced thereon individual recordings of bell tones and a starter length of tape preceeding said recordings clear of recordings, an electric circuit including respectively a tape head, audio gate means, an amplifier and loud speaker combination, a clock mechanism, electric powered tape travel means, timing means and accompanying pre-amplifier means all electrically connected in said circuit, said timing means and accompanying pre-amplifier means being responsive to said starter length of tape and adapted to open said audio gate means to the speaker, said timing means including reset means responsive to pulse recordings on the tape to reset the timing means, counter and comparator means electrically connected in the circuit responsive jointly to said clock mechanism and said timing means whereby reproduction of one or more of said individual pulse recordings will be effected thereby and the remainder of said individual pulse recordings will be silenced, and stop means in said circuit spaced from the individual pulse recordings and electrically connected to the tape travel means acting after reproduction of the last of said individual pulse recordings to stop action of said tape travel means after a decay interval has passed.
Claim 2
Dependent Claim
208 words
A musical tape play system for the reproduction of bell tones comprising a sound tape length having electronically reproduced thereon individual recordings of bell tones and a starter length of tape preceeding said recordings clear of recordings, an electric circuit including respectively a tape head, audio gate means, an amplifier and loud speaker combination, a clock mechanism, electric powered tape travel means, timing means and accompanying pre-amplifier means all electrically connected in said circuit, said timing means and accompanying pre-amplifier means being responsive to said starter length of tape and adapted to open said audio gate means to the speaker, said timing means including reset means responsive to pulse recordings on the tape to reset the timing means, counter and comparator means electrically connected in the circuit responsive jointly to said clock mechanism and said timing means whereby reproduction of one or more of said individual pulse recordings will be effected thereby and the remainder of said individual pulse recordings will be silenced, and stop means in said circuit spaced from the individual pulse recordings and electrically connected to the tape travel means acting after reproduction of the last of said individual pulse recordings to stop action of said tape travel means after a decay interval has passed.
Claim 3
Dependent Claim
25 words
A musical tape play system as in claim 1 wherein said stop means comprises a foil length in the tape following said individual pulse recordings.
Claim 4
Dependent Claim
17 words
A musical tape play system as in claim 1 wherein said stop means comprises a delay relay.
Claim 5
Dependent Claim
27 words
A musical tape play system as in claim 1 wherein there is at least one length of tape carrying a series of pulse recordings comprising a melody.
Claim 6
Dependent Claim
24 words

Claim 7
Dependent Claim
237 words
A musical tape play system for the reproduction of bell tone melodies and clock strike bell tones comprising: a sound tape length having electronically reproduced thereon a bell melody comprising respectively a series of bell pulse imprints, 12 individual pulse imprints, a sensor imprint at one end of said series of bell pulse imprints and, a starter length of tape at the other end of said series of bell pulse imprints clear of imprints, and an electronic circuit including respectively a tape head, audio gate means, an amplifier, a loud speaker, an hour clock having electric contacts, and electric powered tape travel means all electrically interconnected in said circuit, timing means in said circuit responsive to said starter length of tape adapted to open said audio gate means to the speaker, said timing means including reset means operative in the absence of a clear length of tape to reset said timing means, a counter and comparator means electrically interconnected in said circuit responsive jointly to said clock and said timing means whereby only the correct hourly number of individual pulse imprints will reproduce in sequence with the series of bell pulse imprints and the remainder of said individual pulse imprints will be silenced, and stop means in the circuit responsive to tape condition after reproduction of the last of said individual pulse imprints to stop action of said tape travel means after a decay interval has passed.
Claim 8
Dependent Claim
237 words
A musical tape play system for the reproduction of bell tone melodies and clock strike bell tones comprising: a sound tape length having electronically reproduced thereon a bell melody comprising respectively a series of bell pulse imprints, 12 individual pulse imprints, a sensor imprint at one end of said series of bell pulse imprints and, a starter length of tape at the other end of said series of bell pulse imprints clear of imprints, and an electronic circuit including respectively a tape head, audio gate means, an amplifier, a loud speaker, an hour clock having electric contacts, and electric powered tape travel means all electrically interconnected in said circuit, timing means in said circuit responsive to said starter length of tape adapted to open said audio gate means to the speaker, said timing means including reset means operative in the absence of a clear length of tape to reset said timing means, a counter and comparator means electrically interconnected in said circuit responsive jointly to said clock and said timing means whereby only the correct hourly number of individual pulse imprints will reproduce in sequence with the series of bell pulse imprints and the remainder of said individual pulse imprints will be silenced, and stop means in the circuit responsive to tape condition after reproduction of the last of said individual pulse imprints to stop action of said tape travel means after a decay interval has passed.
Claim 9
Dependent Claim
