摘要:
The ring seal and retainer assembly includes an annularly shaped ring seal defining a radial inner surface, a radial outer surface, first and second axial end surfaces and a central bore for fluid or gas passage. A retainer is provided for affixing and positioning a ring seal in a sealing assembly. The retainer includes a circular sidewall sized and positioned to engage and cover the ring seal's radial outer surface. The retainer includes an arcuate flange which extends at one of the retainer's axial extremities to form a concave interior and a convex exterior. Preferably, the arcuate flange extends outwardly to increase the retainer's radius and the arcuate flange is sized to compressibly engage the interior sidewall of the component block's counterbore.

A system allowing a user of a browser program on a computer connected to an open distributed hypermedia system to access and execute an embedded program object. The program object is embedded into a hypermedia document much like data objects. The user may select the program object from the screen. Once selected the program object executes on the user's (client) computer or may execute on a remote server or additional remote computers in a distributed processing arrangement. After launching the program object, the user is able to interact with the object as the invention provides for ongoing interprocess communication between the application object (program) and the browser program. One application of the embedded program object allows a user to view large and complex multi-dimensional objects from within the browser's window. The user can manipulate a control panel to change the viewpoint used to view the image. The invention allows a program to execute on a remote server or other computers to calculate the viewing transformations and send frame data to the client computer thus providing the user of the client computer with interactive features and allowing the user to have access to greater computing power than may be available at the user's client computer.

A method for presenting advertisement images on a display screen, comprising: subdividing a map image into a plurality of geographic regions; associating a first advertisement image with a first region and a second advertisement image with a second region, the first and second regions being ones of the plurality of geographic regions; receiving a signal indicative of a region-of-interest, the region-of-interest being another of the plurality of geographic regions; selecting an advertisement image for the region-of-interest from among the first and second advertisement images; generating a presentation of the region-of-interest, the presentation including a view of the advertisement image; and, displaying the presentation on the display screen.
摘要:
A system is provided for touching up a chipped and scratched painted surface by applying a solvent solution to the surface, applying a selected touch-up paint, and removing a portion of the applied touch-up paint from the painted surface. The removing step includes applying a wax and solvent mixture (e.g., about 40% wax and about 60% naphtha) and then removing a residue of wax and paint by substantially immediately wiping the painted surface with a cloth. The solvent solution may include naphtha. The touch-up paint may have a tone substantially the same as the tone of the painted surface and is slightly darker than the painted surface. The touch-up paint may be prepared by selecting a first paint having the tone that is most similar within the set to the tone of the painted surface and adjusting the tone with a second paint having a tone that is in between the tone of the first selected touch-up paint and the tone of the painted surface, and adjusting the brightness with a third touch-up paint having a tone that is within a same third portion of the color wheel.

An angle grinder is provided including a trigger assembly for selectively actuating the angle grinder. A particle separation assembly is provided for the removal of any dust, particle, or artifacts that may have entered into the housing of the angle grinder. A brush biasing system is also provided to ensure proper and efficient operation of the motor of the angle grinder. An overload monitoring system is included to monitor the loading on the motor. A clutch mechanism is also included to prevent overloading on the motor of the angle grinder. A gear wheel lock mechanism is also provided to prevent the wheel spindle from rotating during installation or removal of a grinding wheel on the wheel spindle. An anti-locking flange system is also included to prevent the over-tightening of the flanges and the grinder wheel during the operation of the angle grinder. A gear case labyrinth feature is also provided.
摘要:
This invention relates to compositions and methods for achieving the efficient aziridination of organic molecules, especially olefins. More specifically, the invention is directed to a mild, selective, and efficient aziridination protocol that involves catalysis by a mixed-valent dirhodium(II,III) catalyst (Rh25+). Especially preferred sources for forming such mixed-valent dirhodium(II,III) catalyst (Rh25+) are dirhodium(II) carboxamidates, such as dirhodium(II) caprolactamate, and their derivatives and analogues.

摘要:
A system and method for authenticating records. Certification information may be encoded in graphical form. This graphical form, or design, may be referred to as an “Indicia.” The record at issue may be printed out by a computer or stored electronically and bear on it an indicia that relates to the authenticity of the document. The indicia (and record) may then be scanned and interpreted by the computer to authenticate the record.
摘要:
A modular system for enabling a distribution of fluids, including a plurality of individual fluid path blocks that can be joined to substrate plates and component interfacing blocks to form gas sticks and gas panels. Each gas path block will have a fluid passageway with an entrance port and exit port accessing a common surface. Active components are mounted to the interfacing blocks, with each gas path block extending and interconnecting across immediately adjacent components in a stick or immediately adjacent sticks. Alignment features are provided to ensure that entrance and exit ports are accurately positioned to facilitate sealing.
