    Abstract: This disclosure is directed to methods of and apparatus for inserting a material, e.g., the reactive paste and used in secondary batteries, into the apertures of an apertured workpiece, e.g., the plate or grid element of a secondary battery, wherein the material to be inserted is deposited on the workpiece, an insertion means, e.g., a roller, is advanced toward the workpiece against the material, and the insertion means is displaced over the surface of the workpiece against the material concurrently with the advancement of the insertion means.

    Abstract: DURR-22-9 PULP-INSULATED CONDUCTOR CABLE A cable of this invention substantially increases the number of pulp-insulated conductor pairs per unit of cable cross-sectional area. This permits a reduction in the outside diameter of a cable without reducing the number of conductor pairs or an increase in the number of pairs in a given area such as in an existing underground duct by utilizing substantially more of the cross-sectional area of the duct than had been used in the past. Each pulp-insulated conductor includes a metallic conductor enclosed in a composite insulative cover which has a controlled dielectric constant and which comprises a pulpous material and a coated layer of adhesive material interposed between the conductor and the pulpous material. The coated layer causes the pulpous material to adhere to the conductor with substantial integrity so that the moisture content of the pulpous material can be reduced over that achieved in prior art processes. This results in a smaller cross-section of each pulp-insulated conductor which allows the use of an increased number of conductive pairs in a given cable cross-section and without any significant increase in mutual capacitance characteristics of the insulated conductor pairs. A cable system for providing an increased number of conductor pairs in an existing duct includes a cable of this invention and a pulling eye attached to an end portion of the cable with the diameter of the cable and of the pulling eye being substantially equal.
