摘要： Wood grain angle information is detected electronically by use of a sensor having a common electrode and a plurality of electrodes spaced from the common electrode and arranged angularly about a sensor axis. The common electrode can serve as a sense electrode or as a drive electrode for the remaining angularly spaced electrodes. By modulating applied drive signals and demodulating the sensed signals that result from capacitive coupling of an adjacent wood specimen, values that are a function of wood grain angle are identified.

摘要： An automated method and apparatus for grading pre-cut lumber products according to selected physical properties thereof such as modulus of elasticity (MOE) and modulus of rupture (MOR) are disclosed. A conveyor transports boards to be graded to an automated lumber feeding mechanism which sequentially rotates each board from a loading to a grading position. In the grading position, an impactor impacts one longitudinal end of the board to generate a compression force and a detector at the opposite longitudinal end converts the compression force to an electrical signal. Data acquisition circuitry samples and stores at least one cycle of the signal and a computer analyzes the samples and assigns values to predetermined parameters which characterize the signal. The computer utilizes the parameter values in one or more predetermined formulas which are optimum statistical predictors of the selected physical properties as a function of the parameters to obtain values for the selected physical parameters. The computer assigns a grade classification to each board according to the grading criteria based upon the calculated values of the physical parameters and a marking mechanism applies appropriate grade indicia to the board.

摘要： Method and apparatus for determining vertical density profiles in wood composites. A fly cutter is rotated across the edge of a wood composite panel to produce acoustic emissions that themselves produce an RMS voltage. The changes is RMS voltage so produced are recorded and thereby the acoustic emission is recorded. The detected signal is transformed into electrical signals, amplified and transmitted to a suitable detecting transducer.

摘要： Moisture in wood veneer strips received from a drying oven is measured by passing the veneer strips on a conveyor between arrays of conducting elements including a pair of transmitting bars on one side of the veneer and a pair of receiving plates juxtaposed therewith on the other. The transmitting bars are energized with signals out of phase with respect to each other on either side of ground, and the receiving plates are likewise disposed to receive the phased signals. When wet veneer passes between the plates arrays, part of the transmitted signal is shunted through the veneer, reducing the signal received by the receiving plates.

摘要： A method and apparatus for rapidly determining the moisture content of a substance. An area of one surface only of the substance is subjected to a predetermined intensity of radiant energy for a selected period of time and the temperature rise is measured. The rise in the surface temperature of the substance such as pieces of wood, is approximately inversely proportional to the moisture content of the wood and thus is easily determined. This is obtainable by transporting the substance on a fixed speed conveyor past a heat source, variations in the rise and fall in the surface temperature readings immediately following the application of heat are representative of its moisture content; low readings indicating high moisture content while high readings being indicative of low moisture content.

摘要： A method and apparatus for screening wood poles to identify those in which rot or other deterioration has occurred to an extent which justifies a more detailed examination, comprises injecting "white sound" into the pole at 40Hz and measuring the amplitudes of vibrational energy at 100Hz and 350Hz opposite the point of injection. A comparison of the amplitudes of these frequencies is used to signify whether the pole has passed the screening. Two such tests are conducted at perpendicular positions on the pole. The screening apparatus may be combined with apparatus for conducting a more detailed examination of the pole if it fails to pass the screening test.
