Abstract: An anvil for use in riveting one element to another element such as belting and a clasp for the belting. The anvil defines at least one aperture, and preferably a plurality thereof, for receiving detachable, rivet-carrying nails, whereby a rivet carried on the nail has an end that faces the anvil. The anvil defines an outer face surrounding the aperture for engaging and shaping the rivet end. The outer face is free of adjacent, upstanding walls beyond the normal diameter of the rivet and outside of and facing the aperture. Accordingly, the rivet end may spread freely outwardly from the aperture as the anvil shapes the rivet end, contrary to the prior art.

Abstract: An apparatus for orienting a fastener in a clasping arrangement with a workpiece, the fastener presenting a first leg and a second leg joined by a bight intermediate the first leg and the second leg, comprises a deflector for engaging the first leg and the second leg. The deflector comprises a generally planar surface and a single cavity intersecting the surface in a substantially elliptical opening having a major axis and a minor axis. The cavity has at least a first interior wall and a second interior wall. The first wall slopes from the opening in a first direction toward a depth limit; the second wall slopes from the opening in a second direction toward the depth limit. The depth limit is substantially coincident with one of the first axis and the second axis.

Abstract: Amine curable compositions containing a partially acrylated epoxy resin useful for forming protective and/or decorative coatings on a variety of substrates, particularly flooring substrates.

Abstract: A belt fastener assembly attachment apparatus attaches belt fastener assemblies to the end of a belt with rivets and with a non-manually powered rivet assembly driving tool. A guide template having a plurality of guide apertures is alignable with the anvil die apertures of an anvil die plate. Each guide aperture receives and aligns the rivet assembly dispensing barrel of the non-manually powered rivet assembly drive tool to the anvil die apertures of an anvil die plate and rivet receiving apertures of the belt fastener. Guide pins carried by the guide template and received within guide apertures of the anvil die plate maintain the guide template apertures in registration with the anvil die apertures of the anvil die plate and the rivet receiving apertures of the belt fastener.

Abstract: A system for affixing a device to a workpiece comprises a dynamic fastener applicator for imparting motion to a fastener with respect to the workpiece by urging the fastener along a path so that the fastener piercingly encounters the workpiece and fixedly engages the device with the workpiece. The system includes a static fastener applicator for effecting clasping engagement of the workpiece and the device by the fastener by a deflecting structure located in the path traveled by the driven fastener which orients the fastener to a clasping configuration for establishing the desired clasping engagement. The system further comprises a positioning apparatus for precisely establishing desired relative positions of the workpiece, the dynamic fastener applicator, the static fastener applicator, and the device for the desired clasping engagement.

Abstract: A dynamic fluid flow measurement apparatus is intended to be connected to a relative reference member, such as a marine vessel. The apparatus preferably includes a base member, a lever mechanism movable relative to the base member for transmitting force corresponding to direct dynamic fluid flow pressure applied to the lever mechanism, and a signal generator disposed in the base member for actuation by the lever mechanism. The signal generator generates an output signal corresponding to the force transmitted through the lever mechanism in response to fluid flow passed the relative reference member. In the preferred embodiment, the signal generator takes the form of a solid state pressure sensing transducer, such as a piezoresistive transducer sensor for sensing force transmitted through the lever mechanism.

Abstract: A dynamic fluid flow sensing system measures relative fluid velocity with respect to a reference member. The system includes a sensor housing supported from the reference member such that the sensor housing is exposed to fluid flowing past the reference member. A solid-state pressure sensing transducer is supported by the sensor housing for generating an electronic output signal in proportion to a sensed dynamic pressure of fluid flowing past the reference member. A central processing unit receives the electronic output signal from the transducer and generates a processed electronic output signal in accordance with a stored control program. A display receives the processed electronic output signal and displays a visual readout of desired fluid flow characteristics based on the processed electronic output signal.
