摘要:
A valve system is provided having a housing including a first end, a second end and a first passageway. The housing has a first port and a second port. A valve member is disposed within the housing and movable relative thereto. The valve member defines a portion of the first passageway that includes a first opening configured for alignment and sealed fluid communication with the first port and the second port. The portion of the first passageway further includes a second opening having a greater relative dimension than the first opening. The valve member is manipulable to establish sealed fluid communication between the first opening and the first port or the second port while maintaining continuous sealed fluid communication between the second opening and the first passageway adjacent to the second end of the housing. The valve member can be disposed within the housing for rotation relative thereto.

A Midwave FLIR imaging optical apparatus has both a narrow and wide field of view. The imaging optical apparatus has a See Spot mode of operation, where a laser designator spot image is superimposed on the FLIR image in the narrow field of view. A laser rangefinder receiver path is also provided. A shared aperture collects incident radiation, which after manipulation by a plurality of optically significant surfaces, projects radiation to a detector. The imaging optical system is lightweight and compact and efficiently transmits FLIR energy and a narrow band of laser energy so that a signal due to a source outside the pass bands of interest (including solar energy) will not adversely effect operation of the imaging optical apparatus.

A honeycomb web precursor includes a body of polymer material having a series of branched slits. The body is capable of expanding into a web of honeycomb construction. Various panels and partitions are also disclosed. A method is also provided for producing a honeycomb web of polymer material. That method includes the making of a series of branched slits in a body of polymer material so as to define multiple expansion ribs and the expanding of the body and erecting of the expansion ribs by folding so as to form the honeycomb web.

A splatter screen may be releasably retained to a cookware item to prevent splatter of hot food items and the like from the cookware item during cooking. A rim of the splatter screen is constructed and arranged to be releasably retained within an upper rim portion of the cookware item. Any number of spring clips may be attached to the rim of the splatter screen for releasably retention of a cover of the cookware item to the splatter screen. A grip portion of a handle, attached to the rim of the splatter screen, is constructed and arranged to accommodate a handle of the cookware item with which the splatter screen is intended to be used.

A system of detecting and adjusting the normal force exerted by a web material around the circumferential surface of a cylinder is provided. Sensors associated with the cylinder surface are wired to a processor that compares detected normal web forces with a set value. An actuation device is activated by the processor to adjust the normal force exerted by the web by, e.g., adjusting the tension in the web material. A positioning device that preferably translates a web-wound spool is also provided as an option for the actuation device.

Methods and apparatus for an improved automated version of a word game that incorporates game play methodology into a central controller and communicates game play information to the players through a game console that provides each player with an input pod for communication with the microprocessor. The microprocessor incorporates features including a timer, scoring system, random letter generator and a random element generator so as to increase ease of use and speed up game play. The microprocessor communicates information to the players through a variety of lights that are selectively illuminated as well as a self-contained speaker for communicating audible information to the players.

Signal converter systems are provided with N analog-to-digital converters that respectively respond to N interleaved clock signals which have a common clock frequency and are further provided with a filter network that processes the converters' output digital sequences with a selected filter passband a filter passband that is contained within a single one of Nyquist zones whose widths are one half of the clock frequency and that is positioned to pass information contained in the analog signal. In a system embodiment, the filter network comprises a symmetric systolic finite impulse response filter arranged to define N input ports for reception of the digital sequences.
