Abstract: An air cleaner includes a housing having first and second opposite ends. A media pack is preferably oriented within the interior volume of the housing. In preferred embodiments, the media pack will have a first and second opposite flow face and be constructed and arranged for air to flow into the media pack through the first flow face, and for air to exit the media pack through the second flow face. The air cleaner will include a seal member forming a seal between the media pack and the housing. In preferred constructions, a secondary filter element is oriented within the interior volume of the housing. In some preferred embodiments, the housing is constructed and arranged as a resonator. Certain embodiments include a seal construction that engages the secondary filter element. Methods of filtering systems, servicing filtration systems, and constructing filter arrangements and housings will use filter elements and constructions as characterized above.

Abstract: The english and trajectory assistant is a device to aid a player of ball and pocket games to properly strike his primary target ball, resulting in a favorable shot. The device is an attachment which can be fastened to any existing playing stick. The assistant simultaneously projects cross hairs onto the primary and secondary target balls without moving the stick from the shooting position. The device is easily removed and replaced with a traditional stick end. The tip is easily replaced by being unscrewed. Shape, balance, and weight of the stick are not altered.

Abstract: A device for removing a heatspreader from an integrated circuit package (ICP) according to the present invention. The device includes a base piece that is preferably made of a suitably rigid and thermally conductive base material such as tool steel. The base piece defines a base cavity that is adapted to receive and engage the heatspreader. The depth of the base cavity is approximately equal to a thickness of the heatspreader. The device further includes a top piece comprised of a suitable top material such as tool steel. The top piece includes a body portion from which an elongated member or handle extends. The body portion of the top piece defines a top cavity adapted to receive and engage the integrated circuit package. The elongated member is suitable for manipulating the body portion of the top piece to apply a torquing force to the ICP package when it is engaged in the top cavity.

Abstract: The present invention is directed to traffic paint compositions, which dry faster than conventional waterborne traffic paints and to a method of producing traffic paint road markings made therefrom. The traffic paint composition of the present invention includes a blend of an anionically stabilized polymer binder, a polyfunctional amine polymer having an amine and an acid functionality therein and an amount of volatile base sufficient to raise the pH of the composition to a point where essentially all of the polyfunctional amine polymer is in a non-ionic state. The traffic paint composition of the present invention further provides improved storage stability.

Abstract: A remote information server contains at least one set of object data bases, with each set including a first object data base containing information content components and a separate second object data base containing context information pertaining to linkages between the information content components of the first object data base of the same set of object data bases. Information content object files respectively containing at least one information content component from the first object data base in the remote information server are delivered to respective local information servers when requested or directed and cached in the respective local information servers. The entire second object data base(s) of context information are delivered from the remote information server to, and maintained in, a plurality of broker/servers. A set of the local information servers is coupled to each broker/server.

Abstract: Data corresponding to a desired shape of a prototype is transmitted to a rapid prototyping system. The system calculates a sequence for extruding flowable material that thermally solidifies so as to create the desired geometric shape. A heated flowable modeling material is then sequentially extruded at its deposition temperature into a build environment that maintains the volume in the vicinity of the newly deposited material in a deposition temperature window between the material's solidification temperature and its creep temperature. Subsequently the newly extruded material is gradually cooled below its solidification temperature, while maintaining temperature gradients in the geometric shape below a maximum value set by the desired part's geometric accuracy.

Abstract: The performance of a computer system displaying polygonal forms is improved by method and apparatus including a cache storage device and related control hardware operating in conjunction with a pipeline graphics display system to reduce or eliminate the redundant matrix transformation of shared vertex data, thereby reducing the processing time required to generate the graphics images displayed for out-the-window simulation.

Abstract: The present invention is directed to a method of producing wear resistant traffic paint composition. In accordance with the method, a traffic marking of a traffic paint composition having low GPC number average molecular weight latex binder when applied to the road surface exhibits improved wear resistance over those traffic paint compositions having high GPC number average molecular weight latex binders. The wear resistance is further enhanced by modifying the latex polymer used in the composition with acetoacetyl functional pendant moiety and amino silane.

Abstract: An electronic control system that accurately maintains oscillation of an optical assembly at resonance. In the preferred embodiment, a signal control circuit delivers an input signal to an optical assembly. A resonance detector detects the difference in phase between the input signal and a feedback signal from the optical assembly. The phase difference is used to determine whether the optical assembly is at resonance. The signal control circuit is responsive to the resonance detector and modifies the frequency of the input signal to oscillate the optical assembly at its resonant frequency. The electronic control system can also maintain multiple optical assemblies at resonance.
