  • Patent number: 6453609
    Abstract: The invention consists of a sonication and imbibition process for the uptake of water and/or other beneficial substances into a seed. The seed to be treated is immersed in water or other liquids. The seed is exposed to sound energy at frequencies between 15 kHz and 30 kHz for periods between about 1 and 15 minutes. The ultrasonic energy generates cavitational forces by the adiabatic collapse of microbubbles in the liquid medium, particularly those bubbles that collapse at the surface of the seed. The ultrasonic cavitational forces impart an enhanced stable memory for the seeds to imbibe water and/or other substances beneficial to the seed and/or plant. The ultrasonically treated seed can be dried, stored, and later imbibed with a substance that enhances a growth characteristic of the seed or resultant plant. Upon germination, the plant maintains the enhanced growth characteristics.

  • Patent number: 6319090
    Abstract: A bandanna is provided with a graphics display area defined on at least one side of the bandanna. The graphics display area is defined on each side by a first and second guideline that extend the length of the bandanna. The first and second guidelines are joined together at a terminal end by a third guideline. The bandanna is initially folded along a center folding line, wherein the graphics display area is substantially centered and adjacent to the center folding line. Next, the bandanna is repeatedly folded and wrapped in a manner that creates successive folding lines each substantially parallel to the center folding line. The folding and wrapping continues until one of the folding lines reaches the third guideline. A tip portion is folded about the third guideline thereby creating a pocket. Then, each side of the bandanna is repeatedly folded and stacked about the first and second guidelines, first one side and then the other.

  • Patent number: 6213058
    Abstract: An animal chute with animal-actuated gates at each end and a data collection area. The animal enters the chute through one of the gates and both gates automatically lock the animal in the data collection area until the data is collected. The opposite gate then unlocks in order to let the animal exit the chute. The animal chute also has a side safety gate which breaks away upon pressure from the animal in order to allow it to escape. Data such as animal identification and weight is gathered in the data collection area. The gates may be operated with a linkage system and electric linear actuators. The data may be transmitted to a personal computer in order for the data to be stored and analyzed. The chute may be controlled with a programmable logic controller. The chute may be used in conjunction with additional directing devices in order to sort animals which pass through the chute.

  • Patent number: 6209063
    Abstract: A computer system that utilizes a method that manages the flow of information between a memory storage area, a display screen, and a cache. The information flow within the computer system is managed by monitoring the initiation of the display screen blanking interval and then selecting a data entry in the cache which corresponds to display memory during the display screen blanking interval, and flushes the contents of that data entry to the memory area. The process repeats for each such data entry in the cache.

  • Patent number: 6183047
    Abstract: A wheel rim including a first wheel rim section having a base and a pair of circumferential support flanges at opposite sides of the base, each of which extends radially outwardly from said base. A second wheel rim section has a base and a pair of circumferential support flanges at opposite sides of the base, each of which curves axially and radially outwardly. The second wheel rim section is sized to fit inside the first wheel rim section with the bases of the respective wheel rim sections in contact engagement. The outer peripheral edges of the flanges of both rim sections meet along the circumference of the wheel rim and are joint together by weldments that extend around the entire circumference of the wheel. The result is a composite wheel rim having an inner contour of a conventional roll-formed wheel rim and an outer, distinct contour.
