Also in certain embodiments, the container includes top panels closing off the top portion of the container. Additionally in another embodiment, the container does not have any top panels at all. Likewise, the container may have solid sidewalls, or the container may have viewing and access cutouts formed in the sidewalls. | 10-02-2008 |
20080237318 | Reusable pop-up container and associated container blank - The present invention includes a blank and container formed of cellulose-based materials configured to form a reusable and collapsible container. The container in the partially assembled, knock-down position lies substantially flat and is capable of being stacked and shipped. Arrival at a job site or at a time requiring the use of the container, the partially assembled knock-down container may be easily converted into a fully erect container ready for use as intended. Once loaded with product, the first and second top panels may be folded down to enclose the container. The container positions the relief scores primarily in the side panels with only a single relief score in the bottom panel. This configuration allows the bottom panel to distend while the container is in the collapsed state while not adversely affecting overall container strength. | 10-02-2008 |
20080237096 | Methods for determining pith direction and location in lumber - Methods are provided for determining a location of a pith along a length of a wood sample. The methods may comprise the steps of: determining pith direction; selecting two areas of the wood sample at which two or more chords of a ring can be defined; bisecting the chords to define a line perpendicular to the chords; and locating at least one intersection point for two or more of the bisecting perpendicular lines. | 10-02-2008 |
20080236463 | Methods of managing timberland - A method of managing timberland generally includes planting a softwood tree crop in first and second rows, wherein the tree crop has a tree spacing between adjacent trees and a row spacing between the first and second rows. The method further includes planting an energy crop in the row spacing, wherein the energy crop is a regenerating lignocellulosic energy crop. The method further includes periodically harvesting the energy crop for a predetermined number of harvests. | 10-02-2008 |
20080236349 | Trim device for a lamination assembly - A trim device for a lamination apparatus is provided. The lamination apparatus provides a cellulous based panel with at least one polymeric layer. The trim device includes a housing and a material removal apparatus at least partially disposed within the housing. The trim device also includes a pressure source in communication with the material removal apparatus. The pressure source is adapted to provide a pressure differential to the cellulous based panel having a waste section. The pressure differential positions the waste section into communication with the material removal apparatus so that the waste section is removed from the cellulous based panel during operation of the trim device. | 10-02-2008 |
20080226852 | Gas barrier packaging board - A paperboard structure having a five layer product side construction with a gas barrier layer which is a blend of nylon and polyethylene terephthalate. | 09-18-2008 |
20080226851 | Gas barrier packaging board - A paperboard structure having a four layer product side construction of a tie layer, a gas barrier layer comprising at least one of aliphatic nylon, aromatic nylon, a blend of nylons, a copolymer of nylons and a blend of nylon with polyethylene terephthalate, a tie layer and a polyolefin layer. | 09-18-2008 |
20080216981 | Method for Conveying, Mixing, and Leveling Dewatered Pulp Prior to Drying - System for conveying, mixing, leveling, and flaking dewatered pulp to produce pulp flakes suitable to be used in a dryer. The system produces a consistent flow rate of pulp and uniform pulp flakes in terms of pulp flake size and pulp flake moisture content. The system includes a rotating shaftless screw conveyor for mixing and conveying dewatered pulp. The system includes a belt conveyor. The pulp is deposited from the screw conveyor onto the moving belt conveyor through a chute. The system includes a rotary doctor. The pulp is leveled with the rotary doctor located above the belt conveyor to produce a substantially even rate of mass flow of pulp along a length of belt conveyor. Uniform and consistent quantities of pulp per unit time can then be fed from the belt conveyor to a pulp flaker that then translates into an even rate of pulp mass flow to the dryer. | 09-11-2008 |
20080213897 | Methods for storing conifer somatic embryo germinants - In one aspect, the present invention provides methods of storing conifer somatic embryo germinants germinated on a sterile germination medium for delayed transplanting into a growth medium. The methods of the invention comprise the steps of: (a) placing the germinants while still on sterile germination medium into a cold environment in which the temperature is in the range of 0.5° C. to 10° C. for a time period up to six months, said germinants comprising a visible, well-defined epicotyl and radicle; and (b) placing the germinants in water for a time greater than about 1 hour at a temperature below about 24° C. prior to transplantation into growth medium. | 09-04-2008 |
20080213896 | Methods for storing conifer somatic embryo germinants - In one aspect, the present invention provides methods of storing conifer somatic embryo germinants germinated oil a sterile germination medium for delayed transplanting into a growth medium. The methods of the invention comprise the steps of: (a) placing the germinants while still on sterile germination medium into a cold environment in which the temperature is in the range of 0.5° C. to 10° C. for a time period up to six months, said germinants comprising a visible, well-defined epicotyl and radical; and (b) placing the germinants in water for a time greater than about 1 hour at a temperature below about 24° C. prior to transplantation into growth medium. | 09-04-2008 |
