  • Patent number: 6533862
    Abstract: A pasting machine is provided for paste of an active material for a lead battery which is capable of continuously applying stably and favorably, not only a paste of active material for a negative electrode, but also a paste of active material for a positive electrode, to a continuous substrate. There is arranged within a hopper 1 a pair of front and rear paddles 2,2 located above, a delivery roller 3 located below, a vaned roller 5′ located at a rear side of the intermediate portion, and an auxiliary roller 4 located diagonally to the upper front of the delivery roller 3 spaced from and opposed to the delivery roller 3. A delivery opening 6a of an orifice plate 61 fixed to the lower end of the hopper 1 is made open to direct paste in the same direction as the travel direction of a continuous, substrate A.

  • Patent number: 5212025
    Abstract: A battery container is provided with a battery cover having side walls so that a gap is formed between the side walls of the container and the side walls of the cover. The upper end portion of a bottomed heat-shielding case is inserted into this gap so that the heat-shielding case is detachably attached to the battery container and covers the container and forms a space between the container and the case. The space between the container and case is closed to air outside the case and air convection between the outside air and the air inside the space can be prevented thereby increasing the heat-shielding effect for protecting the storage battery from high temperatures. Additionally, the heat-shielding case is designed to be attached securely to the battery container (1) to make one body therewith, making it easier to mount and dismount them in an automobile engine compartment.
