Title: Elmer Christensen: Innovator in Wood Processing Technologies
Introduction
Elmer Christensen is a notable inventor based in Kent, WA (US), recognized for his contributions to wood processing technologies. With a total of 2 patents, he has developed innovative methods that enhance the efficiency and value of wood products.
Latest Patents
One of Christensen's latest patents is titled "Process for encapsulation of cellulose based substrates using electromagnetic radiation heating." This method involves encapsulating a cellulose-based substrate with polymeric film by raising the temperature of the films using an electromagnetic radiation source. A pressure differential is created between the environment defined by the films and the external environment, promoting the conformance of the films to the cellulose-based substrates. The result is a complete encapsulation of the cellulose substrate, with the films sealed around its peripheral edges and any defined slots or cutouts.
Another significant patent is the "Log cutting optimization system." This system estimates the velocity of a stress wave induced in a log or tree stem to maximize the value of wood products produced. An accelerometer is placed against the log while it is struck with a pneumatic hammer. By monitoring the signals received at the accelerometer, the velocity of the stress wave can be determined. Based on this velocity, an estimate of the modulus of elasticity (MOE) for the wood in the log is made. A price table is then selected that relates different sizes of lumber with the determined modulus of elasticity to current market values, allowing for optimized cutting of the log to maximize lumber value.
