Patent number: 5433825Abstract: The present invention is directed to a process for pulping of lignocellulosic materials. In the process, the ligoncellulose material is impregnated with an alkaline liquor. The lignocellulose material is maintained in the alkaline liquor for a period of time sufficient to permit infusion of the alkaline liquor and swelling of the lignocellulose material. The alkaline liquor is then drained from the lignocellulose material and the lignocellulose material may be washed with water, although such washing step is not required. The alkaline impregnated lignocellulose material is then immersed in an acidic oxidizing solution comprising peroxymonosulfate anion. The lignocellulose material is maintained in the oxidizing solution for a time sufficient to oxidize at least some of the lignin of the lignocellulose material. Thereafter, a second alkaline liquor is used to solubilize the oxidized lignin.Type: GrantFiled: May 2, 1994Date of Patent: July 18, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventors: James L. Minor, Edward L. Springer

Patent number: 5419500Abstract: The invention concerns itself with an apparatus and method for producing plastic slivers from plastic infeed stock. The splinters produced are especially suitable for use in plastic or cellulosic/plastic composites. The invention will readily accommodate a broad range of types and forms of plastic infeed stock, including waste plastic, whether or not it has been cleaned and sorted into homogeneous feed streams. The method cuts plastic into slivers by firmly holding the plastic infeed stock and slowly feeding it against rotating cutter heads. The feed mechanism automatically adjusts to varying amounts of feed stock. The slivers need no further processing before they can be used in composites.Type: GrantFiled: August 16, 1994Date of Patent: May 30, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Brent W.

Patent number: 5418031Abstract: Batt style insulation comprised of cellulosic and thermoplastic material and a method of making such insulation. A blend of cellulosic material and thermoplastic fibrous material, wherein the latter comprises between 3%-15% of the blend by weight, is formed by a method such as air-laying into a low density, high loft mat. The surface of the mat is flame-treated to melt the thermoplastic component on the surface, forming a skin which keeps the cellulosic component intact. The thermoplastic component in the interior of the mat remains unmelted, thereby providing the mat with a spring-back characteristic which allows the mat to retain most of its original shape and loft even after it has been compressed for shipping. A facing sheet can be applied to the surface of the mat, as is done with conventional fiberglass batt-style insulation.Type: GrantFiled: November 22, 1993Date of Patent: May 23, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Brent W.

Patent number: 5408956Abstract: An electronic fence is utilized to control animal access as an alternative to conventional posts and barbed wire fences. The electronic fencing includes stationary field transmitters with variable ranges placed around the perimeter of an accessible area. Each animal in the area wears a small ear tag receiver. When an animal enters an exclusion zone, the receiver triggers an audible tone, and then shortly thereafter an electrical stimulus. The audible tones and electrical stimuli may be repeated three more times at four second intervals until the animal exits the exclusion zone. If the animal hasn't responded, a safety device in the ear tag locks up or disables the unit to prevent the animal from receiving further stimuli. A remote stationary unlock transmitter located in areas frequented by the animals, such as salt licks, mineral or water sources, unlocks any ear tags which have become locked and thus improves the integrity of the system.Type: GrantFiled: June 21, 1993Date of Patent: April 25, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Thomas M. Quigley

Patent number: 5396799Abstract: A method for the non-destructive evaluation of the integrity of wooden members, in situ, for example, embedded in the soil, employing the reflection of an acoustic wave off of the embedded end of the wooden member. The reflection is caused by the discontinuity in acoustic properties between wood and the supporting medium. The method allows the measurement, at one end of the member, of substantially the entire length of the wooden member without its removal. The acoustic wave is monitored in time and amplitude to provide indications of sound speed and attenuation, measurements which apparently are not unduly affected by coupling losses between the wooden member and its supporting matrix. These measured values may be empirically linked in an equation providing the integrity of the wooden member.Type: GrantFiled: July 13, 1992Date of Patent: March 14, 1995Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Robert J. Ross, Rodney C. De Groot, Earl A. Geske, William J. Nelson, Vyto C. Malinauskas, Diego O. Cuevas

Patent number: 5307679Abstract: A method of evaluating un-dried lumber for its propensity to degrade, during drying couples an acoustic pulse to un-dried lumber and measures the speed of the propagating of the pulse through the lumber. Preferably, the pulse is directed transversely to the lumber's grain. The pulses may be generated by a calibrated weight striking the lumber's surface and detected at two points on the lumber by means of acoustically coupled accelerometers. A timer, triggering on similar portions of the acoustic pulse as detected at the two points provides the necessary information to deduce speed. A speed threshold is determined empirically by studying samples of the lumber type and the speed of acoustic pulses through them and drying them to determine their propensity to degrade.Type: GrantFiled: March 25, 1992Date of Patent: May 3, 1994Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Robert J. Ross

Patent number: 5277854Abstract: Method and apparatus to form grids of open cells from fibers, especially wood fibers and fibers from waste paper and mixed waste materials. The invention utilizes a screen carrying a plurality of elastomeric pads of predetermined sizes arranged thereon in predetermined spaced relation to each other. The fiber is deposited between the pads but not above the pads. The deposited fibers and the pads are compressed normal to the screen, which causes the fiber in the spaces between the pads to be consolidated both normal and parallel to the screen, resulting in a open grid having cells of the shape of the pads. Numerous variations are provided including several continuous production embodiments. The invention uses state of the art technology for virtually all aspects.Type: GrantFiled: June 6, 1991Date of Patent: January 11, 1994Inventor: John F. Hunt
