International Classification:

F41B 502

US Classification:

403270, 403272, 403268, 273416

Abstract:

A self-centering and self-aligning joint is presented for bonding a first and second wood segment, wherein the joint includes a single tenon extending from the end face of the first segment, and a void disposed within the end face of the second segment. And adhesive is applied to the outer surface of the tenon, or to the inner surface of the void to join the two segments.

US Classification:

73597, 73602, 702 56

Abstract:

A system for and method of evaluating a log. The system includes an analysis module having at least one input terminal connectable to the at least one input device. The at least one input terminal is operable to receive at least one signal representing at least one measured property of the log and at least one determined parameter of the log determined in response to an energy being applied to the log. The analysis module further includes a processor coupled to the at least one input terminal. The processor determines a predictive modulus of elasticity (MOE) of the log based at least in part on the at least one measured property and the at least one sensed parameter. The analysis module also includes an output terminal coupled to the processor and connectable to an output device. The output terminal transmits a third signal representing the predictive MOE.

International Classification:

G01N 2908
G01N 2918

US Classification:

73597

Abstract:

A system and method of detecting anomalies and/or grain variations in a wooden member. At least one ultrasonic transmitter applies an ultrasound waveform into a surface of a wooden member so as to generate a multiplicity of ultrasonic waves including, e. g. , longitudinal and shear ultrasonic waves. These ultrasonic waves are measured after propagation through the wooden member by at least one ultrasonic receiver disposed on the same surface of the wooden member. At least one ultrasonic receiver may also be placed opposite the ultrasonic transmitter so as to detect radial transmission of the longitudinal ultrasonic wave at a point across from the wooden member. The received ultrasonic waves are processed to determine anomalies and/or grain variations in the wooden member at positions of the wooden member between the ultrasonic transmitter and the ultrasonic receiver(s). The ultrasonic transmitters and receivers may be placed in rollers to facilitate high-speed, in-line processing of wooden members.

5/792572

Inventors:

John Grover Erickson - Racine WI

International Classification:

A47G 2302

US Classification:

2482203

Abstract:

A clip type hanger for aperture boards for supporting and displaying liquid container cans, such as a collector's array of beer cans or the like. A clip is made of a wire and is in a T-shape in the inverted position for the front view, and one end of the clip extends through a hole in the aperture boards and the opposite portion of the clip snaps on to the upper edge of the can or like item to be supported by and suspended from the clip. The clip is of one piece of bent wire of resilient characteristic and is shaped to have two free ends and a clipped central portion all on one plane whereby the central portion is on one side of the container edge and the free ends are on the other side of the container edge, and the clip is sprung onto the edge for securely holding the container.
