Abstract: This invention is directed to a preparation useful on dairy animals. More specifically, this invention is directed to a preparation for the disinfection of teats and the care of udders of dairy animals which comprises:(a) from about 84.4 to 91.6 percent by weight, based upon the weight of the total preparation, of deionized water;(b) from about 3 to 5 percent by weight, based upon the weight of the total preparation, of glycerin;(c) from about 3 to 5 percent by weight, based upon the weight of the total preparation, of paraffin oil;(d) from about 1 to 2.5 percent by weight, based upon the weight of the total preparation, of saturated C.sub.16 -C.sub.18 -fatty alcohols;(e) from about 0.4 to 0.6 percent by weight, based upon the weight of the total preparation, of an iodine complex with disinfecting action,wherein the content of active iodine is from about 800 to 1200 ppm and the viscosity is from about 25 to 35 sec. as measured at 20.degree. C. in a Ford beaker with a 4 mm nozzle.

Abstract: A row-crop harvester has a frame displaceable in a predetermined travel direction and formed with a plurality of forwardly open throats each provided with a respective conveyor chain each in turn spanned over a respective drive sprocket. Each such drive sprocket is carried on a respective drive shaft having a drive gear that meshes with the drive gears of the conveyor chains to each side. Each drive shaft with its respective sprocket and gear are together mounted in a respective housing bolted to the frame of the harvester and having a mounting flange whose outer periphery corresponds to the pitch circle of the respective drive gear. A main gear meshing with one of the drive gears rotates all of these drive gears simultaneously, and each conveyor chain has a stretch exposed in a respective throat of the machine which is opposite the stretch of the flanking chains for backward advance of cut crop.
