('CSSR) Fo riginal spelling:,Rezae] TITLE: Raising the efficiency of tools by dividing their cutting edges PERIODICAL; Stanki i instrument, no. 12, 1961, 20-24 TEXT: The article contains a general discussion, including calculations, proving that, tools with cutting edges consisting of a series of several teethcut more efficiently than tools.with uninterrupted cutting edges, and are subject to lower forces and wear. The article gives data on tool tests V// that confirmed the productivity-raising effect of dividing the cutting edgesv gmd the results of tests made in the metalcutting laboratory of the Chelya- binskiy traktornyy zavod (Chelyabinsk Tractor Plant) concerning the effect of the shape of chip breakers. The tools tested were three types of round broaches (Fig. 5): a conventional broach a), a broach in which the sue- cessiveteeth were of equal height but the front tooth was narrower than the following tooth b and c and a broach d in which the front tooth 'was Card 1/4 S/121/61/000/012/0031/0()71 Raising the efficiency D040/D112 divided into equal portions so that the width of the cutting edge-equalled the width of the chip breakeri the next tooth had no chip breaker and had the same outer diameter as the,first tooth, so that it removed only the metal left after the chip breaker. The latter broach was found to wear least of all. It is pointed out that-heat liberation in broaching is most intense at.the transition point between the tooth surface and-the chip ,.breaker; the angle X (see Fig. 5) is of primary importance, although the shape of the chip breakers may be different. If the chip breaker is round 3.6)1. anCL (Fi 6, b 2 sin V , so that for2K 8 ~ 450, R = (0-7 for-X = 15 L 25, the radiiis R = (1.2 1.9)1. It is stated that these regu- larities apply to tools of any kind: in many tools these regularities are closely approached and the cutting efficiency is high, but the most effiaieni; tools are the so-called "protyazhki peremennogo rezaniya" ("alternating-cut- ting broaches") of the Chelyabinsk Tractor Flant. It is stated that if the ,chip breakers are located along the cutting teeth sections,,the.efficiency is higher; a twist drill with chip breakers (Fig. 7) is shown' as an exam-oie of this. Such a twist drill permits 251/6 higher feed at equal torque compared. -Conclusions: The cutting eff4ciency with conventional twist drills.

VESTN.0F- ~9 5 ~, '4 '(2 8 - 3 1 Various methods of treatment of the optic nerves are evaluated in this paper. In addition to stimulatLng therapy, the vasodilating drugs, ganglioplegics and neuro- plegics, an important role is played by vitamin B12 treatment. The authors discuss the mechanism of action of this vitamin, its specific relation to the optic nerve and the results of its administration. A conclusion Is drawn that treatment of the optic nerve by vitamin 1312 presents many advantages. r 1.
