    • An automatic fluid-flow control system is provided for controlling the quantity of fluid allowed to flow uninterrupted through a conduit. It is particularly useful in controlling potentially damaging floods caused by breakage in a branch plumbing line used to supply water to beverage dispensing appliances, ice-making machines and similar devices which repeatedly consume limited quantities of water in relatively short flow cycles. The fluid-flow control system includes a flow meter which emits a signal containing information about the flow of fluid and also indicating when fluid is flowing and when it is not. The preferred metering device emits pulses at a rate proportional to the flow rate. A counter accumulates a pulse count during each period of fluid flow. A separate pulse sensing network senses the beginning and end of each period of fluid flow and disables and initializes the counter whenever fluid is not flowing. The accumulated pulse count in the counter is proportional to the quantity of fluid passing through the meter. The counter is set to close a solenoid valve whenever a predetermined maximum pulse count is exceeded. A back-up protective circuit is also provided, employing a timer to measure the time interval of each fluid-flow cycle. When the time interval is exceeded, the timer closes the solenoid valve. In addition to the flood protector mode of operation, a configuration employing the same circuit as a dispenser control device is also disclosed.
    • 提供了一种自动流体流量控制系统,用于控制通过导管不间断地流动的流体的量。 它特别有助于控制由用于向饮料分配设备,制冰机器和类似设备供水的断路引起的潜在的破坏性洪水,这些设备在相对较短的流量循环中反复消耗有限量的水。 流体流量控制系统包括流量计,其发出包含关于流体流动的信息的信号,并且还指示流体何时流动以及何时不流体流动。 优选的计量装置以与流量成比例的速率发射脉冲。 计数器在流体流动的每个周期期间累积脉冲数。 单独的脉冲感测网络检测每个流体周期的开始和结束,并且每当流体不流动时禁用和初始化计数器。 计数器中的累计脉冲数与流过仪表的流体量成比例。 每当超过预定的最大脉冲数时,计数器被设置为关闭电磁阀。 还提供备用保护电路,采用定时器来测量每个流体循环的时间间隔。 超过时间间隔时,定时器关闭电磁阀。 除了防洪器操作模式之外,还公开了采用与分配器控制装置相同的电路的结构。

    • A lighter device having a flow restrictor and associated methods for manufacturing and testing such lighter device and flow restrictor are described. The flow restrictor may be formed of a porous member to achieve a substantially fixed or varying flame height. The flow restrictor may be tested before or after assembly into a lighter housing by receiving a non-combustible fluid therethrough. The flow rate of the non-combustible fluid may be correlated to the flow rate of a combustible fluid through the flow restrictor to approximate the resultant flame height of a lighter incorporating the tested flow restrictor. The flow restrictor may also be tested by receiving a combustible fluid therethrough prior to assembling the flow restrictor into the lighter housing. In this manner, flow restrictors and corresponding lighter devices may be tested without introducing combustible fluids into such lighter devices prior to shipment. Also, a vacuum may be drawn on a fuel tank of the lighter prior to shipment.
    • 描述了一种具有流量限制器的打火机装置和用于制造和测试这种较轻装置和限流器的相关方法。 限流器可以由多孔构件形成,以实现基本固定或变化的火焰高度。 流量限制器可以在组装到更轻的壳体中之前或之后通过从其中接收不可燃流体来测试。 不可燃流体的流速可以与通过限流器的可燃流体的流量相关,以接近结合了测试流量限制器的打火机的合成火焰高度。 在将限流器组装到打​​火机壳体之前,也可以通过接收通过其中的可燃流体来测试流量限制器。 以这种方式,可以测试流量限制器和对应的较轻的装置,而不会在装运前将可燃流体引入这种较轻的装置中。 此外,在装运前可以在打火机的燃料箱上抽真空。

    • A reinforced plastic valve apparatus in a preferred embodiment comprises an upper valve portion, a lower valve portion, an endoskeletal structure configured as a weir support or reinforcing member and an exoskeletal framework configured as a support collar. The upper valve portion preferably includes an upper plastic valve housing or body, a resilient diaphragm and a valve actuator. The lower valve portion comprises a lower plastic valve housing or body that is preferably configured to mate with the upper valve housing to define a valve interior. The lower valve body preferably has an integral weir which, in conjunction with the resilient diaphragm, defines a fluid passage. The diaphragm is configured to sealingly engage and disengage with the weir as effected by the valve actuator. The weir support member is disposable within the lower housing to support the weir.
