摘要： A computing weighing scale is disclosed wherein a single multi-digit numerical indicator is driven in real time by the scale microcomputer to display, sequentially, weight of the article, price per unit weight, and total price or value of the article. The indicators are part of a display which also includes function words identifying the nature of the information to the scale operator and customer. The scale also includes weight code generating mechanism, a keyboard for entering numerical information, and the microcomputer.The single multi-digit indicator can also display tare weight, which is entered via the keyboard when there is no weight on the platter. If tare is entered and subsequent weight on the platter is less than entered tare, the calculating function is inhibited. If platter motion is detected with weight on the platter, the display will reset to the weight indicating condition and then sequence to show again price per unit weight (if entered) and total price. When all weight is removed from the platter, entered tare is erased, tare is, however, remembered during weight changes above zero weight.Price per unit weight can be entered via the keyboard only when there is some minimum weight on the platter and is remembered for possible recalculation if weight on the platter is changed but not removed, price per unit weight is cancelled when all weight is removed from the platter.Keyboard switches are interrogated a plurality times before entered information is accepted, to assure the key entry is valid and switch contact bounce has terminated. The platter motion detector is disabled for a short time after a key actuation, to avoid system resetting as a result of platter movement which may be induced by keyboard actuation.The microcomputer scans the possible inputs from the scale and the keyboard, and sends output signal to the display, at real time rates which are compatible both with human keyboard manipulation and retention.Scale operation is divided into two portions which are called the communicate and compute cycles; the communicate cycle is usually repeated many times between compute cycles in order that real time information sensing and display operation be possible.

摘要： A filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered fluid flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered fluid flowing out of the second portion of the plurality of flutes so that fluid passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the fluid. The filtration media pack can be provided with increased filtration media compared with commonly used z-media packs. Techniques for increasing the amount of filtration media available for filtration include increasing the flute density, reducing masking, adjusting flute width height ratio, increasing flute density, adjusting flute shape, and reducing plug length. Techniques for increasing performance while reducing initial pressure drop are also provided. A filter element containing the filtration media pack is provided, and the filter element includes a seal member extending around a periphery of the filtration media pack. A method for manufacturing a filtration media pack and a method for using a filtration media pack are provided.

摘要： Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units, such as breather caps. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate and/or fluid mist load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.

摘要： A barrier system for use with a trafficable surface that penetrates a boundary to control access by vehicles and to permit uncontrolled access by pedestrians. The system includes a turntable providing a surface that is rotatable generally in the plane of the trafficable surface. Impact elements are arranged along the surface in a pattern having a spacing configured to permit passage by pedestrians and to prevent passage of vehicles when the turntable is in a first position and to permit passage of vehicles when the turntable is rotated to a second position. The system controls vehicle traffic across the boundary by moving the turntable between the first position and the second position.
