Re (cont'd) design with a heavy lug attached which has three set screws to hold the cable in position before being sweated in. 5. The vents are of a double type, a hole being drilled in the cell top & a ring of celluloid fixed round it leaving about 3/8" clearance all round then a small vent is placed in this hole, & a larger one is fixed (a push in fit) in the ring of celluloid which covers the smaller vent over. The densities of these cells will not be able to be taken due to the connecting bars passing under & close up to the bottom of the vent. 6. The elements are of the block type & are quite strong & rigid as far as they can be inspected. Signed (cont'd) This Sheet must be filed on completion of the work. | ||
