摘要： Water treatment devices that include filtration media with specified grain size distributions are provided. In one arrangement, the device contains a volume of grains such that between about 1 and 15 vol % of the grains have a grain size in a range between a first grain size and a second grain size, a first portion of the grains have grain sizes smaller than the first grain size, and a second portion of the grains have grain sizes larger than the second grain size. The first grain size can be between about 50 and 100 μm and the second grain size can be between about 100 and 150 μm. In other arrangements, the first grain size can be between about 70 and 90 μm and the second grain size can be between about 100 and 130 μm. The difference between the first grain size and the second grain size can be at least 20 μm. In other arrangements, the difference between the first grain size and the second grain size can be at least 10 μm.

摘要： A ventilated toilet for removing odors from the toilet base includes a unitary molded tank assembly with an integral ventilation cavity formed along the base and the back inside of the water tank. At least one water channel connects a water inlet chamber of the base to the water tank and is configured to channel water into the base when released from the tank, as well as to provide an airflow conduit for odors present in the base to be removed from the base via the ventilation cavity. A flush valve extends through the ventilation cavity to connect the tank and the base, and is sealed in attachment to eliminate egress of odors. The system permits substantial elimination of odors at flush volumes of 1.6, 1.3 or 0.8 gallons per flush by virtue of the enhanced seals and unitary construction. A toilet tank assembly in accordance with the invention is also disclosed.

摘要： A closure for pipeline pig sender or receiver includes a primary closure body and a secondary closure body. The primary closure body has an outer face, an inner face and a port extending therethrough from the outer face to the inner face. The primary closure body is secured to the pipeline pig sender or receiver sealing a closure end when the primary closure body is in the closed position. The secondary closure body closes the port on the primary closure body. The secondary closure body is movable between a closed position and an open position to enable an operator to insert a tool through the port into the diversionary passage to manipulate the pipeline pig and release trapped pressure prior to opening the closure. The secondary closure body is secured to the primary closure body sealing the port when the secondary closure body is in the closed position.

摘要： Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising strips of fluted material secured to facing sheets, oriented in a stack. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The media pack is non-removably secured within a filter cartridge housing, at a location between opposite sections of a shell, typically secured thereto with an adhesive. The shell also defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack. The closed end is typically curved and the shell typically provides either a d/b-shape or a u-shape. The filter includes an end member, with a outlet flow aperture arrangement therein, allowing for outlet flow from the filter cartridge in a general direction orthogonal to air flow through the media pack. The air cleaner assembly includes a housing having features for receipt of, and engagement by, the filter cartridge. An optional secondary filter cartridge is provided, mountable on the housing in an orientation projecting into a clean air volume in the main filter cartridge.

摘要： A Static Random Access Memory (SRAM) having a split write control is described. The SRAM includes bit, write, and write-word lines. Each memory cell within the SRAM includes a delay which is coupled to a dedicated write-word line. When a cell is not being written, its delay receives a delay signal on its associated write-word line, which increases the response time of the cell. When a cell is to be written, however, its delay receives a bypass signal on its associated write-word line, which decreases the response time of the SRAM cell.

摘要翻译： 描述具有分离写入控制的静态随机存取存储器（SRAM）。 SRAM包括位，写和写字线。 SRAM内的每个存储单元包括耦合到专用写字线的延迟。 当单元未被写入时，其延迟在其相关联的写字线上接收延迟信号，这增加了单元的响应时间。 然而，当单元被写入时，其延迟在其相关的写字线上接收旁路信号，这降低了SRAM单元的响应时间。
