Abstract: A battery paste application machine is equipped with a battery paste application hopper assembly. The battery paste application machine can be employed in a larger manufacturing operation to produce lead-acid batteries. The battery paste application hopper assembly furnishes automated control of one or more parameters of battery paste delivery. Volume of battery paste at the time of delivery can be automatically controlled, pressure of battery paste at the time of delivery can be automatically controlled, or both volume and pressure can be automatically controlled. Depending on the parameters controlled, the battery paste application hopper assembly can include a housing, a paste delivery roller, a feed roller, a scraper bar, a first actuator, and/or a second actuator.

Abstract: A process and apparatus for extracting plant oil from plant material by cooling an alcohol solvent to a temperature of ?40° C. or lower, contacting the plant material with the cold solvent to extract plant oil to provide a solvent and plant oil mixture, heating the mixture to convert the solvent to a gaseous state to thereby separate the solvent from the plant oil, and cooling the separated gaseous solvent to a liquid to recover the solvent.

Abstract: Apparatus for piling in stacks a plurality of successive individual battery plates moving at a high rate of speed. Synchronized plates are transferred to a carrier conveyor which advances them into work stations with the leading edge of each plate raised generally vertically above its trailing edge. Sequentially in one and another of the stations, each plate is rapidly stopped so that a plurality of succeeding synchronized plates are each disengaged from the carrier and deposited in a stack on an elevator underlying each station. The elevator is retracted as each plate is deposited so that the next plate can be received on the stack. Periodically, the depositing of plates is switched from one station to another and stacks of plates are removed from the elevator associated with each station so that another stack can be formed on the elevator.

Abstract: A machine for casting battery grids in a continuous manner includes a rotary cylindrical drum in the outer peripheral surface of which the battery grid pattern is machined as a cavity. A shoe is arranged against an arcuate segment of the peripheral surface of the drum. An orifice slot in the shoe has an opening at the peripheral surface of the drum. Molten lead under superatmospheric pressure is directed into the orifice slot in an amount in excess of that required to fill the grid cavity on the drum through the opening in the orifice slot as the drum rotates. Means are provided in the shoe for maintaining the molten lead in the orifice slot in a highly fluid condition and for causing the lead filling the grid cavity to solidify rapidly as it advanced beyond the opening of the orifice slot.
