摘要: A visual alarm device monitors the condition of a control and indication circuit and gives a distinct visual alarm upon detection of an abnormal condition in the monitored circuit. The device uses the indicator lights of the monitored circuit itself to give the visual alarm. The alarm device interconnects with the monitored circuit locally requiring no new cabling and remains in a passive state until an abnormal condition is detected. When the monitored circuit is rendered inoperative by a thermal overload trip, the alarm device becomes active to flash the indicator lights to provide a distinct visual alarm. Included in the device is a test switch, an appropriate voltage converter, an oscillator, and a power indication light.

摘要: An embedded geometrically variable filter underdrain header and a method for constructing such a filter. Often the variation is a decrease in cross section along the header from the backwash media source, which avoids a pressure loss as liquid is diverted to the laterals along the header. The header is formed inside a filter underdrain basin and is embedded in the basin. The method for constructing the basin and header includes providing a mold for the basin and the header and filling the molds with concrete by pouring concrete into the area between the interior of the mold for the basin and the exterior of the mold for the header. After the concrete cures, the mold for the basin may or may not be removed, while the mold for the header is kept in place.

摘要: An electrically heated cigarette smoking device includes a heater unit, heater blades for applying heat to portions of a cigarette that is supported within the heater unit, the heater unit having an opening adapted to receive an end of a cigarette and adapted to position the end of the cigarette in proximity to the heater blades, and the heater unit defining at least part of a suction flow passage through which ambient air is drawn into contact with the cigarette when a smoker draws on the cigarette positioned in the heater unit. The heater unit is mounted within a partition that positions the heater unit relative to the housing and at least partially defines a bypass flow passage in fluid communication with ambient air surrounding the housing, the partition further defining a flow diverting passage leading from the bypass flow passage to the suction flow passage and through which ambient air is drawn from the bypass flow passage when a smoker puffs on a cigarette inserted in the heater unit opening. A flow sensor is positioned in the flow diverting passage to provide a signal indicative of a smoker taking a puff on the cigarette.

摘要: An apparatus for treating water includes a vertically extending contact vessel, wherein water is contacted with ozone, and a return vessel which contains a column of water of a sufficient height to drive water through downstream filtering stages. Ozone is removed from the water and the rate of ozone injection is monitored and automatically adjusted so that no great amount of ozone remains in water entering the filtering stages. The ozone is generated in elongated elements that are cooled by the process water and that are positioned to serve as a static mixer for such water.
