摘要： Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable. A clutch permits the user to discontinue dispensing material from the device at the selection of the user, and automatically discontinues dispensing of material when the apparatus is driven in a reverse direction. Switches are provided for selectively adjusting the speed of rotation of the impeller, and the pattern at which material is propelled from the impeller. An override clutch permits the impeller to rotate after movement of the apparatus ceases, and a clutch housing is provided to reduce noise during operation of the apparatus.

摘要： Acid is removed from cathodic electrocoating baths by a process in which electroconductive sub-strates are coated with cationic resins present in the form of aqueous dispersions, at least a portion of the coating bath being subjected to an ultrafiltration where the ultrafiltration membrane retains the cationic resin to form an ultrafiltrate which contains water, solvent, low molecular weight substances and ions and at least a portion of the ultrafiltrate is recycled into the coating bath, and at least a portion of the ultrafiltrate is subjected to a special electrodialysis treatment before being returned into the electrocoating bath.
