A nurse distribution system provides dual capabilities for planting different seed varieties from a single planting mechanism. The air cart carries two tanks in which different seed varieties can be placed. The nurse mechanism selectively distributes seed from one tank to the on-row singulation meters, yet can switch to the seed in the second tank to correspond to different soil conditions encountered by the planting mechanism. The planting mechanism carries a first line from the first tank to the nurse receiver and a parallel second line from the second tank to the same nurse receiver. By keeping the nurse receiver as small as possible, thus having a small seed reservoir, the seed variety selection can be switched from one tank to the other in an effective manner.

A pothole repair machine utilizes hot mix asphalt material to fill the pothole being repaired. The machine includes a heating apparatus for raising the temperature of the surface of the road surrounding the pothole to soften the material for bonding with the material to be inserted into the pothole. A hot tack spray is then placed onto the surface of the pothole before hot mix material is deposited into the pothole cavity. Before depositing the hot mix material, a sensing mechanism determines the depth of the pothole and causes an adjustment of the height of screening doors to effect the uncompressed height of the filling material at a predetermined percentage of overfill before a vibrating roller compresses the filling material to the level of the surrounding roadway. A plurality of screening doors extends along the transverse width of the machine, each door being adjustably controlled by a depth sensor member.

The device incorporates a display screen on which a graphic image of a pair of lungs filling and emptying to encourage the user into a predetermined breathing pattern known to reduce stress levels during a training period. After the completion of the training period, the device presents a score reflecting the percentage of times the user achieved high, medium and low relaxation states, and a pie chart reflecting the distribution of the states of relaxation calculated during the training period.

A method for processing municipal waste substantially reduces the volume of material to be disposed into a landfill by increasing the volume of materials of value collected from the municipal waste and by composting the remaining materials to create a salable product. The process includes the removal of materials of value by magnetic devices to extract ferrous materials, by an air classifier to extract light plastic materials, by an eddy current mechanism to extract aluminum materials, and by a plastic sort mechanism to extract large plastic materials. Composting can be accomplished with a composting vessel that is located in the process either before the materials of value are removed or afterward. A grinding of the materials before a final screening allows the commercial grade compost to be separated from the materials that are to be sent to the landfill for final disposal. An alternative embodiment of the process utilizes a steam pressure vessel to disintegrate the waste material and to destroy any pathogens before materials of value are removed and the small and fine materials are composted. Large materials can be gasified to create heat energy for use in the steam pressure vessel.

A safety needle assembly has a rigid housing that encloses a locking mechanism cooperable with actuator that slides over the tip of the needle to prevent accidental sticks after the needle has been used.
