    • A remote control circuit breaker and contactor system having at least one I/O circuit functioning as an interface between a central processing unit and a plurality of up to 32 devices such as remote circuit breakers for each I/O circuit, each remote circuit breaker having an individual electronic circuit which receives commands from the I/O circuit to turn the breaker or contactor on or off or hold and also senses the state of the breaker contacts and the control line and upon request sends back status codes which are stored in the memory in the I/O circuit to be read when desired by the central processing unit. Four-state status information is provided including open, closed, tripped and problem (low voltage, open or shorted control line). Contact state is determined by directly measuring the contact resistance in single break contacts (or solid state device contactors) or the contact voltage in double-break contacts. The I/O circuit provides noise rejection using measured noise as a threshold to minimize the effect of electrical noise on the status communication signals coming from the remote breaker electronic circuit. In the event electrical noise on the control line or the like causes rapid turn-on and turn-off of the remote breaker, a rapid cycle inhibit circuit for a timed interval stops such cycling of the remote breaker after a predetermined number thereof to prevent damage to the remote device due to overheating. The remote breaker electronic circuit affords manual control of the breakers or contactors and trip indication of the breakers in addition to computer control through the I/O circuit. The system uses tri-state communication circuitry which includes a hold command and prevents unwanted state changes during losses of power or when a control line shorts to ground or opens.
    • 一种遥控断路器和接触器系统,其具有至少一个I / O电路,用作中央处理单元和多达32个设备之间的接口,例如用于每个I / O电路的远程断路器,每个远程断路器具有 单独的电子电路,其从I / O电路接收命令以打开或关闭断路器或接触器或保持,并且还感测断路器触点和控制线的状态,并且根据请求发回存储在存储器中的状态代码 在要由中央处理单元读取的I / O电路中。 提供四态状态信息,包括开路,关闭,跳闸和故障(低压,开路或短路控制线)。 接触状态通过直接测量单断路触点(或固态器件接触器)中的接触电阻或双断路触点中的接触电压来确定。 I / O电路使用测量噪声作为阈值来提供噪声抑制,以最小化电噪声对来自远程断路器电子电路的状态通信信号的影响。 在控制线路等上的电气噪声导致远程断路器的快速接通和关断的情况下,用于定时间隔的快速循环禁止电路在其预定数量之后停止远程断路器的这种循环以防止损坏 由于过热导致远程设备。 远程断路器电子电路除了通过I / O电路的计算机控制之外,还可以手动控制断路器或接触器以及断路器跳闸指示。 该系统使用包括保持命令的三态通信电路,并且在电力损失期间或当控制线路短路到地或打开时防止不期望的状态改变。

    • A remotely changeable thermostat for a refrigeration or air conditioning system and method and system employing same. The thermostat has a fluid filled capsule with a diaphragm movably responsive to fluid expansion and contraction for actuating, via lever means, a compressor power switch. The capsule senses temperature via a fluid filled capillary. A separate remote user activated switch energizes an electrical actuator for moving the fulcrum of the lever means to change the sensed temperature of the evaporator at which the power switch is actuated. The user activates a remote switch to energize an electrical heater coil for heating a bimetal strip which moves the fulcrum for the lever means between a high or low temperature setting for compressor power switch actuation in response to user opening or closing the remote heater switch.

    • A resistance wire sensing overcurrent protection module (CSM) for an electrical supply circuit (SC) having a hot temperature sensing diode (32) mounted at the center portion (8c) of an M-shaped resistance wire (8) connected in the supply circuit and an ambient temperature sensing diode (20) mounted on a substrate (18) supported between the supply terminals (4a-b, 6a-b), both diodes being connected to respective pairs of terminals (12a-b, 10a-b) mounted on a header (18) along with the supply terminals. A cover (46) is mounted on the header and filled with glass micro-balloons (48) to isolate thermally the two diodes. A constant current circuit (49) supplies constant current to the two diodes which operate a differential amplifier (52) having an output proportional to the temperature difference as a measure of supply current. This output trips a Schmitt trigger comparator (54) when the supply current rises to an overload value.
