Abstract: A scanning system to analyze wood and determine defects includes at least two ultrasonic transducers configured to scan the wood from edge to edge by triangulating the wood. The at least two ultrasonic transducers are configured to find splits and shakes.

Abstract: A machine tool has a mechatronic assembly which has a machine spindle and has a tool head which is held on the machine spindle and which has a basic body and also at least one working slide, which is adjustable relative to the basic body, for holding a tool. The mechatronic assembly contains an electric adjusting motor which acts on the working slide. The machine tool has a support device which holds the mechatronic assembly and which has an articulated joint arrangement at which the mechatronic assembly can be pivoted at least about a first axis and about a second axis which differs from the first axis.

Abstract: At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn.

Abstract: At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn. The geometric characteristic may be captured by one or more scanners, for example one or more laser scanners. The geometric characteristic may, for example be a measurement of thicknesses, widths and/or wane dimensions.

Abstract: A system for attaching an accessory attachment to a rotary hand tool of the type having a body with a generally cylindrical nose end portion through which an output shaft passes. The preferred embodiment of the system has an attachment that has an attaching end which matingly engages the nose end portion of the hand tool, and includes a rotatable coupling with inner threads that engage outer threads on the nose portion. The nose portion of the hand tool also has at least one recess which is configured to receive at least one projection on the attachment which accurately angularly positions the attachment on the hand tool. The preferred embodiment has at least one complementary tapered recess and projection combination which facilitates easy insertion of the projection into the recess during attaching.

Abstract: An apparatus for beveling the edges of workpieces, such as flooring strips, as they are advanced along a path of travel on a conveyor. The apparatus has a motor assembly which mounts a cutting wheel, and the motor assembly is mounted for manual adjustment in both the in and out and up and down directions. Also, the motor assembly can float a limited distance in both of these directions. A guide shoe is mounted to the motor assembly and is positioned to ride on the workpieces. Any unevenness in the straightness, thickness, or width of the workpieces is detected by the guide shoe, which causes the motor assembly and thus the cutting wheel to closely follow the changing contour of the workpieces and impart a uniform bevel.
