摘要： A system for stopping a spinning table saw blade is comprised of a pin assembly disposed adjacent to a saw blade assembly for stopping a spinning saw blade. A receiving block is disposed on a side of the saw blade opposing the pin assembly for receiving the tip of the pin assembly. A driving assembly is coupled to the pin assembly for driving the pin assembly into the spinning saw blade into the receiving block. Finally, a sensing assembly is coupled to at least one of the saw blade assembly and the driving assembly for sensing encroachment of a user's hand in a pre-defined zone. In use, upon sensing a user's hand the sensing assembly signals the driving assembly to stop the spinning saw blade by driving the pin assembly through the saw blade and into the receiving block.

摘要： A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots. Among other benefits, such flow control features reduce any tendencies for flow separation of the primary fluid in the diffuser.

摘要： A lightweight, remote-controlled, self-propelled equipment support and transport system is stabilized against unwanted angular deviation in each of three perpendicular axes and adapted for motion at high speed along a simple tubular monorail. The system can be quickly and efficiently ground-mounted on stands, suspended horizontally from brackets or from a variety of overhead supports, or vertically mounted alongside a mast or wall. The system includes an elongated drive car running on and partly surrounding a rail, and an equipment support associated with the drive car and configured so that the supported equipment is transversely and longitudinally spaced and balanced about a point just below the center of the rail. The equipment support is mounted in angular isolation relative to the drive car by a system of damped pivots about pitch and yaw axes. The drive car includes a steering adjustment adapted to counteract slight variations in wheel alignment that might tend to drive the transport off-level when in motion along the rail.

摘要： A method and apparatus for covering a ribbon of optical fibers with a resin. The resin is polymerizable under the effect of UV radiation and forms a protective covering surrounding and holding the fibers. The method includes a pre-polymerization step during which the coated fibers advance through a UV irradiating chamber having a pre-polymerization ultraviolet radiation power of less than one fourth of the total power required to polymerize the resin, which is just sufficient to initiation polymerization. This step is followed by a polymerization finishing step during which the pre-polymerized ribbon is subjected to UV radiation of higher power than the radiation produced during the pre-polymerization step, which completes the polymerization process.

摘要： An apparatus for the automated processing of bulk mail which incorporates a number of operating stations that serve to accomplish the various aspects of mail extraction, as well as the subsequent processing of extracted documents, and which are operatively associated with one another to serially process envelopes and extracted documents in continuous fashion and substantially independent of their characteristic features. To this end, the operating stations of the apparatus are configured to be as independent as possible of the characteristics of the envelopes and their contents so that envelopes and contents of varied characteristics can be effectively handled by the apparatus without requiring any significant adjustments. As a result, the apparatus is made capable of processing (as a single job if desired) envelopes and contents of varied characteristics, reducing the need to remove non-conforming envelopes and contents from further processing, and increasing the versatility and productivity of the apparatus.
