engaged by a plurality of clamping screws :30 which extend through tapped holes in the side strip 14. In some cases; it may be desirable'to omit one or both of the plates 17 and I8, and, when this is done, the resistance stripmay preferably be sunk'into suitable slots which may be prorided in the I claim my invention: 1. A resistance unit comprising a conducting ribbon having a plurality of slots: alternately open at opposite edges. said ends of the heating bars in orderthat they may be suitably protected trout unury.
current-carrying capacity, and said slots being unequally spaced to increase the resistance of the ribbon adjacent to the ends of the group.
