Abstract: A system and method for removing a coating from an elongated metal part or a bundle of such parts is described. The disclosed system includes a soaking vessel that contains a solution suitable for degreasing the metal part and softening the coating thereon. An ultrasonic cleaning vessel containing an aqueous cleaning solution cleans the coating off of the metal part by ultrasonic agitation. The system further includes at least one rinsing vessel for rinsing the cleaning solution of the cleaned part, and a drying vessel for rapidly and thoroughly drying the part after it has been rinsed. In the disclosed process, the elongated metal part, or a bundle of such parts, is/are soaked in a solution that is maintained at an elevated temperature for a time sufficient to soften the coating. The elongated metal part is then subjected to ultrasonic agitation in an aqueous cleaning solution bath at an elevated temperature for a time sufficient to loosen and dislodge the coating from the elongated metal part.

Abstract: A method and apparatus for processing used empty aluminum and steel cans wherein groups of empty cans are carried upwardly on an inclined conveyor between spaced inclined ribs and separately sequentially discharged therefrom into an air duct wherein empty cans are blown to a crusher whereat the empty cans are sequentially crushed and fall onto a magnetic separator whereat crushed aluminum cans are separated from crushed steel cans and fall into a weigh hopper whereat the weight of crushed aluminum cans is determined whereupon compensation is dispensed for the value of the crushed aluminum cans. Thereafter, the crushed aluminum cans are sequentially dropped into an air duct and blown to a storage bin.

Abstract: A system for controlling electrical energy consumption according to a user-set kilowatt limit and an automatic kilowatt limit calculated in a microprocessor. Power is limited by regulating an electric hot water heater according to a preset program and, if necessary, by lowering room temperatures due to electric heater cut back. The device features a computer-controlled display and simplified keyboard which permits the user to enter only valid data. The device also features program fail, power fail, and static detect circuitry to prevent computer error.

Abstract: An apparatus for accurately dispensing predetermined amounts of fluid sealant onto can ends which comprises a dispenser arm mounted at one end for horizontal and vertical arcuate movement, a clamp for releasably holding the arm in one operative position, a can end hold down located on said dispenser arm and capable of reciprocal and rotational movement, and a proximity sensor responsive to the reciprocal movement of said can end hold down to generate a control signal when the can end hold down is approaching the apex of its reciprocal movement and dispenser mounted on said dispenser arm proximate to said can end hold down and capable of dispensing a predetermined amount of fluid sealant onto a can end in a predetermined location in timed response to the signal from said proximity sensor.

Abstract: Conveyor apparatus for conveying articles such as flat annular can ends and for controlling the rate of feed of the articles. The articles are transported through a conveying conduit defining an elongated passage with an inlet opening for receiving the articles and an outlet opening for discharging the articles. Feed control apparatus is associated with the conduit, preferably near the outlet opening, for controlling the rate of feed of the articles and comprises resilient liner means associated with the conduit means and located at least partially within the passage for frictionally engaging articles in the passage and controlling the rate of movement of the articles therethrough and force applying means associated with the resilient means for forcing the resilient means into frictional engagement with the articles in the passage. The force applying means is used to control the amount of friction exerted by the resilient means on the peripheral surface of the articles.
