Continuous switching for control systems

Claim 1

A SYSTEM-CONDITION CONTROL DEVICE FOR REGULATING A PLURALITY OF SYSTEMS INDEPENDENTLY, COMPRISING: (A) INDEPENDENTLY OPERATING SYSTEM-CONDITION SIGNALING MEANS, FOR EACH SYSTEM UNDER REGULATION, COMPRISING INDIVIDUALLY ADJUSTABLE SYSTEM-CONDITION SENSING MEANS FOR EACH SYSTEM, ON-OFF SWITCH MEANS RESPONSIVELY ASSOCIATED WITH SAID SENSING MEANS, AND A SOURCE OF SIGNAL CURRENT IN CIRCUIT WITH SAID ON-OFF SWITCH MEANS; (B) ONE AMPLIFIER FOR THE SEVERAL SIGNAL CURRENTS; (C) A FIRST MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING EACH SIGNALING MEANS WITH SAID AMPLIFIER; (D) INDIVIDUAL, TWO POSITION LATCHING RELAYS FOR ONOFF CONTROL OF SYSTEM-CONDITION ALTERING MEANS FOR EACH SYSTEM UNDER REGULATION; (E) A SOURCE OF CURRENT FOR ENERGIZING COILS OF SAID LATCHING RELAYS; (F) A RELAY WITH COIL RESPONSIVE TO CURRENT FROM SAID SIGNAL CURRENT AMPLIFIER, SAID RELAY HAVING IN CIRCUIT WITH SAID LATCHING RELAY ENERGIZING CURRENT A NORMALLY OPEN SET OF CONTACTS, WHICH CLOSE IN RESPONSE TO RECEIPT OF AN AMPLIFIED SIGNAL, AND A NORMALLY CLOSED SET OF CONTACTS; (G) A SECOND MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING LATCHING RELAY ENERGIZING CURRENT FLOWING THROUGH THE SAID NORMALLY OPEN SET OF CONTACTS, WHEN CLOSED, TO SAID INDIVIDUAL LATCHING RELAYS TO ENERGIZE COILS CORRESPONDING TO APPROPRIATE CONTACT POSITIONS THEREOF AND A THIRD MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING LATCHING RELAY ENERGIZING CURRENT, FLOWING THROUGH THE SAID NORMALLY CLOSED SET OF CONTACTS, TO SAID INDIVIDUAL LATCHING RELAY TO ENERGIZE COILS CORRESPONDING TO OPPOSITE CONTACT POSITIONS THEREOF, SAID FIRST, SECOND, AND THIRD MULTIPLE CONTACT SWITCHES BEING ADAPTED TO MAINTAIN CORRESPONDING SEQUENCE RELATIONSHIP TO INDIVIDUAL SYSTEMS UNDER REGULATION.

Claim 2

A SYSTEM-CONDITION CONTROL DEVICE FOR REGULATING A PLURALITY OF SYSTEMS INDEPENDENTLY, COMPRISING: (A) INDEPENDENTLY OPERATING SYSTEM-CONDITION SIGNALING MEANS, FOR EACH SYSTEM UNDER REGULATION, COMPRISING INDIVIDUALLY ADJUSTABLE SYSTEM-CONDITION SENSING MEANS FOR EACH SYSTEM, ON-OFF SWITCH MEANS RESPONSIVELY ASSOCIATED WITH SAID SENSING MEANS, AND A SOURCE OF SIGNAL CURRENT IN CIRCUIT WITH SAID ON-OFF SWITCH MEANS; (B) ONE AMPLIFIER FOR THE SEVERAL SIGNAL CURRENTS; (C) A FIRST MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING EACH SIGNALING MEANS WITH SAID AMPLIFIER; (D) INDIVIDUAL, TWO POSITION LATCHING RELAYS FOR ONOFF CONTROL OF SYSTEM-CONDITION ALTERING MEANS FOR EACH SYSTEM UNDER REGULATION; (E) A SOURCE OF CURRENT FOR ENERGIZING COILS OF SAID LATCHING RELAYS; (F) A RELAY WITH COIL RESPONSIVE TO CURRENT FROM SAID SIGNAL CURRENT AMPLIFIER, SAID RELAY HAVING IN CIRCUIT WITH SAID LATCHING RELAY ENERGIZING CURRENT A NORMALLY OPEN SET OF CONTACTS, WHICH CLOSE IN RESPONSE TO RECEIPT OF AN AMPLIFIED SIGNAL, AND A NORMALLY CLOSED SET OF CONTACTS; (G) A SECOND MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING LATCHING RELAY ENERGIZING CURRENT FLOWING THROUGH THE SAID NORMALLY OPEN SET OF CONTACTS, WHEN CLOSED, TO SAID INDIVIDUAL LATCHING RELAYS TO ENERGIZE COILS CORRESPONDING TO APPROPRIATE CONTACT POSITIONS THEREOF AND A THIRD MULTIPLE CONTACT SWITCH CAPABLE OF SEQUENTIALLY CONNECTING LATCHING RELAY ENERGIZING CURRENT, FLOWING THROUGH THE SAID NORMALLY CLOSED SET OF CONTACTS, TO SAID INDIVIDUAL LATCHING RELAY TO ENERGIZE COILS CORRESPONDING TO OPPOSITE CONTACT POSITIONS THEREOF, SAID FIRST, SECOND, AND THIRD MULTIPLE CONTACT SWITCHES BEING ADAPTED TO MAINTAIN CORRESPONDING SEQUENCE RELATIONSHIP TO INDIVIDUAL SYSTEMS UNDER REGULATION.
