Latest Patents

Christensen’s latest patents include the following inventions:

1. **Apparatus for Selective Sorting of Material Chips**

This innovation pertains to a system designed for sorting pulp wood chips based on a predetermined maximum thickness. It features multiple disk members arranged in rows that rotate separately, allowing for the intermeshing of adjacent rows to ensure selective sorting. The unique contour of the disk members prevents thicker chips from passing through, enhancing the precision of the sorting process. Moreover, the rows are driven in the same direction, with adjacent disks operating at different peripheral speeds for improved efficiency.

2. **Screening Apparatus**

This rotary screen is engineered to separate wood or other particles of a specific size from undesired materials such as fine, moist sawdust. The design includes suspended balls beneath the screening surfaces that leverage gyratory motion to create a pendulum-type action. This mechanism effectively loosens clogging particles from the screen openings. The apparatus also includes a dust pan to collect undersized particles, with additional balls positioned beneath to maintain the cleanliness of the collection area.
