In addition, under the conditions at the Magadanskiy avtoremontnjy zavod (Magadan Automobile Repair Plant), experience of which is reported in the article, this method of strengthening helps to achieve a saving on long-distance -delivered cutting tools. Physical phenomena are described which occur during the discharge treatment of tools, and also relationships in Ihe transfer of hard alloys from the electrode onto the part being strengthened. Results of experiments conducted with the UPR-ZM discharge outfit (made by "TsNILelektrom") are reported in the form of graphs and tables for various treatment conditions and various types of Card 1/2 Card Z/2 LITVIN, J.G.

As :3hortcomings of the book he mentions inadequate treat- ment of the synthesis of monomers, lack of information oil technolog:Lcal problems, and insufficient treatment of USSR work in the field of synthetic rubber.

PURPOSF:; This book is intended for chemists and technicians in the synthetic rub- ber industry and may be wied to acquaint students of organic chemistry with camiercial elastomeric products. COVH1WZ: The book analyzes trends in the technical development of synthetic rub-, ber production outside the Soviet Union. The author used literature surveys cciapiled under his directioa from 1954 through 1956 by a group of specialists of the Technical Council of the Ministry of Chemical Production and other non- Soviet materials. In pa-i-ticular surveys on the technology of emulsion poly- merization by N. A. FerTu)r and A. Ye. Xalaus and on special-purpose syntbetic card L/4 Madam Production of Synthetic fkbbers Abroad SOV/4215 rubbers by N. P. Apukhtira were used. There are 11 tables and 200 references: 7 Soviet, 1 French, 172 lhglish,, and 20 German.

In this figure 1 is the target, 2 is the boundary of the pole pieces, 3 are slits, 4 are nuclear emulsions and 5 the trajectories of charged reaction products. Sections of linear boundaries of the uniform magnetic field which pass (by extension) through the target were thus chosen as the focusing elements. The reaction products leaving the target pass through slits '3 (Fig 1) located at the mid-points of the linear sections of the field boundary and are Card 1/2 focused on the focal surface which is shown by the 82876 s/12o/60/000/02/007/052 E032/E414 Multispectrograph - A New Magnetic Analyser for Charged Products of Nuclear Reactions arcs 4 in Fig 1. A high vacuum is maintained over the path of the charged particles. The instrument can be used to obtain simultaneously nine energy spectra of reaction products at nine values of the exit angle 9 of the reaction products, measured from the direction of the bombarding beam and in the angular range between 0 and 900. Each such spectrum includes particles differing in energy by a factor of 10. The solid angle subtended by each channel is 5 x lo-5 sterad. The resolving power achieved experimentally was 1.2%. The magnetic field was produced by permanent magnets which, in addition to the high stability of the field, ensured small dimensions and weight. The total weight of the multispectrograph was about 600 kg. There are 2 figures and 4 references, 3 of which are English and 1 Soviet.

The energy spectrum of the reaction products was recorded by means of a novel magnetic analyzer, a so-called multispectro- graph (described in Refs- 5, 6). Films -1-5 mg/cm2 thick were used, vizi Polyethylene film (carbon target), quartz film (0- and Si-target), and Si (in natural isotopic composition) per -O.?@L silver.

From a comparison with n the theory it follows, e. g., that the excited 5-946-Mev level of the Si 29_nucleus has negative parity and a spin of 3/2 or 1/2, etc. (cf. Table).

The double focusing of particles of a given energy using a homogeneous magnetic field of the sector type can be generalized to apply to the case of the spectrograph, To do this the exit boundary of the homogeneous magnetic field must be given the special form defined by E(IAI) (RefJ-. V,,F,Kitv1n, PTE; no,-3t 1961@ 33)@ This article preaents an approximate solution of' tlii.-!s equat-.on using a graphical method and keeping to the notation used in Ref.l. If a family of exit boundarie5 are drawn for a given el (t, = 1, and only those parts of the boundaries to the actual focusing are examined) the position of the boundaries changes according to their distance from the point of entrance of the trajectory into the magnetic field, At the centre of the family there is a particular boundary at which the curve changes sign, The greatest part of the optimum boundary can be considered to be a straight line.
