Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
249 words
A system for automatically introducing a chemical, from a metering device, through a chemical introducing means into two or more simultaneously operating programed washing machines, for a predetermined time interval which comprises: an electrical circuit which includes an automatically resettable timing means, settable for the predetermined time interval, means for activating the chemical introducing means in response to the timed interval and means for receiving and relaying a signal from the programmers of the washing machines to the automatically resettable timing means, said receiving and relaying means associated with each washing machine comprising in combination; means for receiving and holding a signal from a washing machine programmer; a first signal blocking means, activated by a signal from a first washing machine programmer which has activated the timing means, to prevent reactivation of the timing means, by a signal from a second washing machine programmer, before termination of the predetermined time interval; signal time delay means which delays the signal from the signal holding means to permit the timing means to reset after the predetermined time interval; a second signal blocking means, associated with the circuits of all other simultaneously operating washing machines in the system, which passes the signal from the programmer of a first washing machine programmer, when the timing means is not activated by a signal from a second washing machine programmer; and means for directing the chemical introducing activating means, to the chemical introducing means associated with the washing machine whose programmer activated the timing means.
Claim 2
Independent Claim
249 words
A system for automatically introducing a chemical, from a metering device, through a chemical introducing means into two or more simultaneously operating programed washing machines, for a predetermined time interval which comprises: an electrical circuit which includes an automatically resettable timing means, settable for the predetermined time interval, means for activating the chemical introducing means in response to the timed interval and means for receiving and relaying a signal from the programmers of the washing machines to the automatically resettable timing means, said receiving and relaying means associated with each washing machine comprising in combination; means for receiving and holding a signal from a washing machine programmer; a first signal blocking means, activated by a signal from a first washing machine programmer which has activated the timing means, to prevent reactivation of the timing means, by a signal from a second washing machine programmer, before termination of the predetermined time interval; signal time delay means which delays the signal from the signal holding means to permit the timing means to reset after the predetermined time interval; a second signal blocking means, associated with the circuits of all other simultaneously operating washing machines in the system, which passes the signal from the programmer of a first washing machine programmer, when the timing means is not activated by a signal from a second washing machine programmer; and means for directing the chemical introducing activating means, to the chemical introducing means associated with the washing machine whose programmer activated the timing means.
