Abstract: The invention relates to a fodder radish. More particularly, a fodder radish (Raphanus species) suitable for use as a multiple grazing fodder crop for livestock is provided. The invention also relates to the seeds, and to the plants of the radish. It also relates to methods of producing a Raphanus plant type having the characteristics of recovery from grazing to give the potential for multiple grazings over many cycles.

Abstract: A powered toothbrush provides movement of cleaning elements which replicate the preferred method of cleaning teeth, namely up-and-down movement on the surface of the user's teeth. This preferred movement is obtained by translating rotational movement of a motor, first into reciprocation movement within the toothbrush through the interaction of a cam follower and helical tracks, and then translation of the reciprocating movement into oscillating movement of the cleaning elements through a limited arc. The translation of rotational to reciprocating movement is achieved through interaction of a cam follower in a helical track. The translation of reciprocating movement to oscillating movement is achieved through reciprocating movement of a volute through a mating groove in the head of the toothbrush.

Abstract: A shutter system for covering a wall opening includes a retractable and deployable barrier assembly and at least one pair of cooperating support braces. The barrier assembly and each brace define respective holes for receiving fasteners that will be used to attach the pair(s) of braces together to reinforce the barrier assembly. When deployed, the barrier assembly covers the wall opening and defines an inside surface proximate the wall opening and an outside surface facing the source of any displacement forces. Each pair of support braces includes an interior brace that is mountable within the wall opening and an exterior brace constructed for positioning against the outside surface of the barrier assembly. The fasteners are inserted through the holes in the exterior support braces, then through the holes in the barrier assembly, and finally through the holes in the interior support braces during use of the system.

Abstract: A priority based licensing system is provided. According to the invention, right to use licenses are allocated to users based on the priority rating of the users. Accordingly, licenses may be reallocated from low priority to high priority users when no unallocated licenses are available. The present invention allows organizations to efficiently utilize a limited number of licenses required in connection with the utilization of a resource.
