Abstract: IMPROVED REVERSING RATCHET              ABSTRACT       A ratchet is provided in which directional indexing is achieved by rotation of an indexing member in the rotational direction in which it is desired to rotate a workpiece.          Locking in an indexing position is achieved by means of detent mechanisms situated in a channel extending through a guide element and biased radially outward therefrom to interact with said indexing member.  A pawl is provided within a cavity defined between a guide element extending from a torque transmitting member and an encircling annular ring at the end of the work handle.  One surface of the pawl is of arcuate configuration equipped with ratchet teeth engageable with corresponding ratchet teeth on the interior surface of the annular ring of the work handle.  An opposing surface of the pawl is of overall convex configuration so that the pawl may be rolled across a planar bearing surface of the guide element under the influence of the directional indexing member.          In this manner engagement of a workpiece may be effected by the torque transmitting member as desired in either of two opposing directions of rotation.

Abstract: Abstract of the Disclosure A method for sorting articles of produce, such as tomatoes, according to color and for separating non-vegetable matter, such as rocks and dirt clods, from the produce.  The produce articles including the non-vegetable articles are passed at an inspection position where a first electrical signal is produced in response thereto.  This inspection position is illu-minated and reflected light from the produce articles is re-ceived to produce a second electrical signal which corresponds only to a predetermined amount of received visible light at first wavelength associated with a desired color characteristic of the produce article to be retained.  A third electrical signal is produced as a result of received invisible light at a wavelength that is absorbed by the produce article to be retained but not by non-vegetable articles.  Those produce articles that produce all three electrical signals are directed along a path different from the path containing the other articles absent of either one of the second and third signals.
