Abstract: A sewer cleaning machine includes a frame, a drum rotatably supported by the frame, and a motor supported by the frame and coupled to the drum. The drum includes a cable that is selectively extendable out of the drum. The motor is operable to rotate the drum. The drum is configured to engage a surface to facilitate moving the sewer cleaning machine along the surface.

Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: A sharpening device with an abrasive material, a polishing coat encapsulating the abrasive material and an instruction card coupled to the polishing coat. The abrasive material having a property of conforming to the shape of a pointed article penetrating the abrasive material and a property of applying resistance pressure to the pointed article. The sharpening pad may be used in the sharpening and polishing of conically and other shaped points as found on various articles such as machine and hand sewing needles, quilting needles, pins, darts, miscellaneous tools, barb-less fishhooks and the like, including various fine pointed articles.

Abstract: A break apart modular flag and coupler for an ATV, includes a plurality of shaft segments, a plurality of break away couplers corresponding to said shaft segments coupling said plurality of shaft segments, a break away base coupler removably joining said one of said plurality of shaft segments to an ATV, and a flag attached to one of said plurality of shaft segments.

Abstract: An orbital rotary blade sharpener for sharpening rotary cutter blades and other rotary blades includes a bottom blade holding portion having a center and a perimeter edge, a top blade holding portion rotatably connectable to said bottom blade holding portion, having a perimeter and a center, a central shaft portion extending from said bottom blade holding portion through said top blade holding portion over which a rotary blade can be fitted, a radial shaft portion extending through said top blade holding portion positioned between the perimeter and the center of the top blade holding portion, and grinding portion connected to said radial shaft portion, and within said top blade holding portion, positioned to be orbitally revolvable around said bottom blade holding portion center and contactable with a blade held between said top and bottom blade holding portions.

Abstract: A conical point sharpener for sharpening conical shaped points such as fishhooks, needles, surgical instruments includes a handle, a mandril with an abrasive material coating fixed to one end of said handle, a drive spindle, wherein said drive spindle is movably attached to said handle and envelops said mandril, an outwardly protruding tapered opening on said drive spindle, and a precision point alignment nest, formed between said abrasive material coating on said mandril and said drive spindle, such that when the conical point to be sharpened is placed in said outwardly protruding tapered opening of said drive spindle, the item to be sharpened is located in said precision point alignment nest and the point of the item is touching said abrasive material coating on said mandril so that the user can then rotate said drive spindle while holding the item to be sharpened, thereby conically sharpening the point as the item to be sharpened rotates around said mandril.

Abstract: A method of producing an aircraft assembly tool for supporting an aircraft component comprising the steps of: determining the predetermined positions and orientations in space at which the component should be supported; designing a fixture frame to provide support at predetermined locations of the frame associated with said predetermined positions; constructing the fixture frame by selecting elongate members having predetermined lengths and connecting the elongate members together with releasable fasteners; constructing a plurality of pick-up devices, each having a receiving element for carrying the component; mounting the pick-up devices to the fixture frame at the predetermined locations; and moving each receiving element about/around the orthogonal axes to align the receiving element with a respective predetermined position and orientation.

Abstract: This invention provides a method of producing an aircraft assembly tool for supporting an aircraft component comprising:

Abstract: A method of producing an aircraft assembly tool for supporting an aircraft component comprising calculating a plurality of predetermined positions and corresponding orientations in space at which the aircraft is to be supported, designing a fixture frame at predetermined locations of the frame associated with the predetermined positions, constructing the fixture frame, providing pick-up devices with receiving elements, securing the pick-up devices to the fixture frame, and adjusting each receiving element.

Abstract: A primary goal of the present invention is to improve the prior art assembly system. The present invention provides a boat of simple ultra light construction with the fewest number of parts that can be easily assembled without tools. Then, when disassembled provides a compact lightweight package suitable for long range or rough terrain portage or back packing. A plastic coated nylon waterproof cover or like skin can be conveniently slid onto, and off of the assembled hull and quickly fastened in place to provide waterproofness for the hull. Another goal of this invention is to introduce a watercraft construction method whose components can be made from extruded corrugated plastic and other plastic materials that are lightweight, but strong, and can be inexpensively mass produced using rule dies and the like inexpensive tooling and assembly methods.
