Abstract: A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by rapid growth rate, fairly strong central stem tendency, slightly earlier than average in time of leafing, and fair straightness thereby producing fair to good timber qualities. The new variety has fair nut bearing qualities. Nut crops are biennial and heavy in some years. Nut-bearing begins early in life of tree, average 2 nuts per cluster, and produces kernels which exceed about fifteen (15) percent of nut weight. The nuts are small and ripen late. The pistillate flowers mature mid-season while pollen maturity is very early to mid-season. In most years there is some overlap in female and male flowering. Flowering begins early in the life of the tree. This new variety of black walnut tree was discovered by the applicant near Bentonville in Fayette County, Ind., in a cultivated area.

Abstract: A drum brake, primarily for a trailer, which gives normal braking torque in forward direction and low torque in reverse. This is achieved by having a pivoted lever acting between the one ends of two shoes remote from the ends between which the brake actuator is located. The shoes act on the lever at different effective radii and the forces applied by the shoes to the lever hold it in a first position during forward rotation, thus allowing normal braking torque, and a second position during reverse rotation which allows the ends of the shoes acted on by the actuator to move apart thus allowing a limitation of the reverse braking torque by limiting the stroke of the actuator.
