Abstract: A laminar is formed from a plurality of sections, where in one example, one or more of the sections are selected to have a configuration according to a known parameter or characteristic of the section, for example material characteristics. One or more sections are cut from a raw material or stock material according to the known parameter or characteristic, which for example can be a known characteristic of the stock material such as roll direction.

Abstract: Tool bodies, tools and machines for operating the tool include electronic circuits for providing data, collecting data, analyzing data and for controlling machines based on such data. Tool bodies and tools may include electronic circuits having data collecting sensors, which may be embedded in a housing with the electronic circuit and/or positioned outside of such a housing. Sensors include temperature sensors, motion sensors, strain sensors, moisture sensors, electrical resistance sensors, position sensors, antennas, and other components.

Abstract: Tool cores may have removable sections, which may be removable without damaging, cutting or severing attachment configurations for the removable sections. The removable sections may be handled simultaneously. Moving parts used to facilitate removal of the removable sections may be secured in a pre-loaded configuration.

Abstract: An interchangeable concrete cutting chainsaw cutting assembly adapted for installation upon a drive assembly in exchange for a removed, different type cutting head assembly. The chainsaw cutting assembly includes a housing that has fasteners that releasably attach the housing to a drive assembly in an installed configuration. A ration transmission has a plurality of interconnected rotation member, each rotatable member having a mounting shaft positioned at a fixed location on the housing by a bearing assembly. The driven member has a receiver that interconnects with a driveshaft of the driver assembly in the installed configuration whereby the driven member is rotated by the drive assembly. The cutting chain drive member operatively interconnected with a drive sprocket whereby rotation of the cutting chain drive member rotates the drive sprocket. The chainsaw cutting assembly is pivotable relative to the drive assembly.

Abstract: A support assembly for a core drill uses an improved reinforcement. The reinforcement can include an extension extending between a center of the tool and a perimeter of the tool the extension can be a non-planar structure having a channel along a portion of the structure. The reinforcement can include a slanted element that can be associated with the extension, that can be formed monolithic with the extension, or otherwise combined with an extension. Multiple slanted elements can be used to form an extension. A top plate can be included for strengthening the reinforcement.

Abstract: A support assembly for a core drill which utilizes an improved high strength spoked reinforcer. The reinforcer may be removably mounted a core drill tube by fasteners. A drive connection is removably mounted and centrally located on an outer disc of a pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The assembly can also include a split in the disc when the high strength spoked reinforcer is not welded thereto, thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith.

Abstract: Chain bar apparatus and methods are disclosed that may be formed from plastic, metal or other materials. Laser cutting of a chain bar core can provide improved structural characteristics, for example when adhesive is used to assemble the chain bar. Flow diversion elements can be used to optimize flow throughout the chain bar.

Abstract: Tools are described having removable working elements, include saws having removable cutting elements. Interface geometries on one or more of a core structure and removable elements may be simple or complex geometries. Securement elements releasably hold the removable elements in place.

Abstract: A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.

Abstract: Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and a second layer that are oppositely disposed. The first and second layers include working surfaces that support at least one working element when the working element is applied to a work piece. Additionally, an intermediate structure is included between the first and second layers. The intermediate structure can include a plurality of components extending in the area between the structural surfaces and the working surfaces.

Abstract: A bolt on drive assembly for a core drill which utilizes an improved high strength spoked reinforcer mounted beneath a disc. The disc and high strength spoke reinforcer are removably mounted on the tube by bolt fasteners. A drive connection is removably mounted and centrally located on a outer disc of the pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The system can also include a split in the disc when the high strength spoked reinforcer is not welded thereto thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith. An adapter is provided that allows for standard drilling that fits into a recess in the center hub and is removable to expose the recess for attachment to a specialized drill motor, such as an A-flange.
