  • Air-root-pruning container
    Patent number: 4510712
    Abstract: A vertical air-root-pruning container involving a series of vertical air gaps displaced around the sidewall of a container. The air gaps are alternately displaced outwardly or inwardly to air-prune spiral root growth in both the right and left directions or are equipped with deflecting means to make the pruning effect bidirectional. Such a container inhibits spiral growth, promotes root branching, and results in more even root distribution as well as increased root growth in the growing medium.

  • Method of depositing doped amorphous semiconductor on a substrate
    Patent number: 4348428
    Abstract: A method of depositing a doped amorphous semiconductor on a base material including the steps of subjecting the base to an environment including a semiconductor gas such as silane or germane, a dopant gas such as arsine, phosphine, or diborane, and mercury vapor, and exposing the base in such environment to ultraviolet radiation to effect decomposition of the semiconductor and dopant materials onto the base.
