Abstract: A sprinkler head for scattering diluted medical fluid, such as fluid fertilizer and nutritive agents, on cultivated vegetables comprising a main body connected at one end to a sprinkler head and at another end to a faucet supplying water. The main body includes a plurality of water flowing passages, an open passage connected to a medical fluid bottle, and a mixing passage. The open passage includes a passage narrowing portion for sucking medical fluid from the medical fluid bottle by increasing water flow speed relative to the rest of the open passage.

Abstract: In a pull type forage harvester which travels forwardly in a field to pick up crop material and feed it into a housing having a cutterhead with knives rotatable around a transverse axes. The cutterhead chops the crop material and deposits it in a transverse trough having an auger which carries the crop to a lateral discharge location. The improvement comprises a corn processor adapter to which chopped corn is conveyed over a floor to an upper and a lower roll rotatable on axes parallel to the cutterhead. The rolls form a bite to receive the corn and pass it between them to crush the kernels therein. The upper roll is positioned close to the cutterhead knives and in crop stripping relation thereto. The lower roll is positioned over the auger to hold down chopped corn thrown upwardly out of the trough.

Abstract: A jaw crusher for crushing rocks combines a hydraulic adjustment of the bite with an air spring tensioning arrangement which maintains a desired tensile force even with variation of the bite. The air spring arrangement is reliable in the dirty environment and also has long life. The use of several air springs in combination with a pressure sensing arrangement adds a safety factor. The more consistent tensioning force allows adjustment of both the tensioning arrangement and the bite of the rock crusher during operation thereof.

Abstract: A fishing reel drag mechanism includes a spool for a fishing line, a brake drum attached coaxially to the spool, and a resilient circular brake shoe positioned inside the brake drum. The outer diameter of the brake shoe is slightly smaller than the inner diameter of the brake drum. A gap is provided on the brake shoe, and a movable spreader is positioned in the gap. When the spreader is moved to a first position, the brake shoe is in a relaxed position spaced from the brake drum, so that the spool may rotate with zero drag. When the spreader is gradually moved to a second position, the gap is gradually expanded by the spreader, and the brake shoe is gradually expanded against the brake drum. The drag on the brake drum is thus adjusted by changing the width of the gap with the spreader. Grooves arranged concentrically around the brake shoe provide additional compliance which improves smoothness in drag application and the range of drag force provided.

Abstract: This invention, is a PROCESS, for creating a flashing red light at a railroad-highway grade crossing.This PROCESS is accomplished by the use of two units. The first unit houses a light that is capable of casting a very intense beam out ahead of the train. It also houses a means to oscillate this light from side to side (left and right) using a motor mechanism, like a heavy duty windshield wiper motor.The second unit is a round, red reflector that is capable of reflecting the light in both directions down the roadway that intersects the railway. This PROCESS is accomplished as the oscillating light beam strikes the red reflector for just a split second with each pass, creating the appearance of a flashing red light, which causes motorists, and others, to know that a train is approaching the grade crossing.The reflector is shaded from the sunlight, leaving it in relative darkness. This enable motorists to see the reflection (the flashing red light) even during daylight hours.
