Abstract: A self-purging separator for separating impurities from fluid intermittently pumped from a well or the like having a segregating device adapted to be received in such a well for segregating impurities from the fluid for descent of the impurities in such a well and a valve below the segregating device for accumulating the descending impurities when the fluid is being pumped and releasing such impurities for further gravitational descent in such well when the pumping is interrupted.

Abstract: A land leveling device having a frame supported on wheels for earth traversing movement forwardly thereof; a first pair of blades borne by the frame in rearwardly convergent oblique relation to each other; a second pair of blades borne by the frame rearwardly of the first pair in rearwardly divergent oblique relation to each other; and means for deploying the frame in a substantially horizontal attitude substantially continuously during said earth traversing movement.

Abstract: A night fishing signal for use with a fishing pole having a fishing disposition, the signal having a flexible, light transmitting outer container which has a bulbous end portion and is provided with a first chemiluminescent reactant; a second, breakable container disposed within the outer container and provided with a second chemiluminescent reactant which forms a chemiluminescent liquid on contact with the first reactant; and a clip fixed to the outer container for mounting the signal on the pole with the bulbous portion downwardly disposed so that, upon breaking the inner container by flexing the outer container, the liquid collects in the bulbous portion visually to signal movement of the pole when a fish is hooked on the line.

Abstract: Disclosed is an agricultural implement for cultivating about trees and vines. The implement includes a frame that mounts four gangs of disc blades, two forward and two aft. The disc blade gangs are relatively movable to set up a variety of discing patterns and the gang can be so mounted on the frame that the lateral extensions of the frame do not extend above the height of the disc blades.

Abstract: A method for picking closely spaced rows of plants using a harvesting machine having spindle-type picking heads; a method of modifying a conventional harvesting machine to harvest closely spaced rows of plants; and a harvesting machine having spindle-type picking heads for harvesting closely spaced rows of plants.

Abstract: A method for eliciting responses from animals to moving, visually discernible stimuli; and an apparatus for providing a moving visually discernible stimulus for eliciting responses from animals.

Abstract: An instrument for extracting splinters and the like, having a hollow elongated handle; a pair of resilient arms, the arms being mounted externally on the handle, having jaws disposed outwardly of a tip end of the handle, and extending along the handle toward its opposite end; a rod having a piercing end at the tip end of the handle and being slidably received within the cavity for movement between an operating position in which the piercing end extends outwardly of the jaws and a sheathed position in which this end is adjacent to the tip end; a spring urging the rod toward the sheathed position; a plunger extending within the cavity at such opposite end to engage the rod and having a button to press the rod into the operating position; a latch mounted on the plunger for latching the rod in this position; and a trigger operable by pressing one of the arms toward the handle to unlatch the rod from the handle for return by the spring to the sheathed position.

Abstract: A work implement having a tubular handle, a tool having tines mounted within the handle for movement between an extended position and a retracted position, and a pendulum-action tool mounted on the handle.

Abstract: A plum tree characterized by its close similarity to the Late Santa Rosa (unpatented) plum tree but from which it is distinguished by ripening 5 or 6 weeks earlier and by the absence of the dark purple band along the ventral suture, which is characteristic of the Late Santa Rosa.

Abstract: A plum tree generally similar to the Santa Rosa plum tree (unpatented) which it most nearly resembles, ripening twenty days earlier than the Santa Rosa, and bearing fruit having medium red skin and mild, delicately-flavored flesh.

Abstract: A nectarine tree, generally similar to the Firebrite Nectarine Tree (unpatented), which it most nearly resembles, bearing large, yellow-fleshed fruit which ripens eight to ten days earlier than that of the Firebrite.

Abstract: A new and distinct variety of nectarine tree generally similar to the Fantasia (unpatented) which it most nearly resembles but from which it is distinguished by producing fruit having a more extensive red skin color, fewer cleft sutures, a rounder shape and brighter ground color.

Abstract: A plum tree generally similar to the Simka Plum Tree (U.S. Plant Pat. No. 1,882) which it most nearly resembles, bearing large, dark purple fruit, but which ripens about three weeks later than that of Simka, is larger, and is clingstone.

Abstract: A peach tree generally similar to the Flavorcrest Peach Tree (unpatented) which bears large, smooth, nearly globular fruit having a more highly-colored skin than that of the Flavorcrest and ripening about three days earlier than the Flavorcrest.

Abstract: A pear tree, denominated "San Joaquin", having fruit ripening for picking about June 11 and to full maturity about June 20, at early maturity having deep green ground color with a brown-red blush in a partially solid, partially striped pattern, the ground color lightening to reach a bright yellow at full maturity and the blush a cherry red.

Abstract: A new and distinct peach tree denominated as "Pampaian's Late Babcock" generally resembling the Giant Babcock Peach Tree (U.S. Plant Pat. No. 11,353) but bearing fruit ripening about one month later and having a distinctly-colored, roughly-textured suture line.

Abstract: A plum tree which is generally similar to the Black Beaut Plum Tree (U.S. Plant Pat. No. 3,617) which it most nearly resembles, bearing purple-skinned, clingstone fruit having redder flesh and a thicker stone than that of the Black Beaut.

Abstract: A new and distinct variety of plum tree which is somewhat similar to the Laroda Plum Tree (unpatented), concurrently with which it bears fruit which is characteristically larger in size, deeper and fuller in external color and possesses a substantially greater amount of red coloration in its flesh.

Abstract: A plum tree substantially as illustrated and described characterized by its bearing fruit which is generally similar to the fruit of the Frontier Plum Tree (unpatented) which ripens at substantially the same time and from which the present variety is distinguished by its more globular shape, deeper red flesh and milder flavor.
