T he cross-section views show w hat hap pens to wire rope, in F ig . j. L a u g h lin 's *'Fist-Grip" Safety Clip holds the rope with hardly any distortion (note hem p cen ters). In F ig . 2, hem p center under U shows how rope is squeezed and flattened by U -b olt's smaller bearing area and " F in ger-Pinch". B oth were tightened to sam e tension by torque-indicating wrench. Here's Why "Fist-G rip " Clips Work Better Laughhn Safety Clips have identical saddles, flat sides; hold rope firmly without crushing. Saddles fit snugly against " liv e " and " dead" ends. Few er clips deliver full rope power. T h e only clips with drop-forged bolts. T est them, for your rope's sake. Distributed through m ill, mine and oil field supply houses. W rite for catalog.

Kaiser, head of Permanente Cement Co., that effective December 6. the company would reduce the base mill price by 20c per barrel for Northern California and Western Nevada. In making this 12 percent reduction Mr. Kaiser emphasized his belief that it would help to counteract "the pres ent Inflationary trend' in the cost of home building. The new price will be $1.45 a barrel as compared with $1.65. It is believed that the other northern California producers will meet the new price cut. A new element of competition was introduced as the $1.45 mill price will make the Northern California price level from 30 to 35c a barrel below that calculated for Southern California, following a 20-cent a bar rel upward price adjustment per mitted by OPA in September. Pric ing methods between Northern and Southern California producers are not the same, the north using an f.o.b. mill price quotation w'hich adds freight to destination and the south functions under a zone system which produces quotations at destination. Southern California's comparable price would be around $1.70 to $1.75 a barrel.
