ABSTRACT: In designing wire-wound resistance elements used in
electrical control appar~ Itus it is assumed that the power
consumption under continubus operating conditions does
not depend on the wire diameter or the winding pitch or
upon the way in which the resistance elements are
arranged. In fact, of course. these fautors greatly
influence the conditions of heat emission from the resis-
tance wire,, The usual formula for the heat balance of a
resistance element operating under steady conditions is
given and its weaknesses are explained. Expression (9)
is derived to exDress the relationship between the
variables that govarn the steady-state thermal conditions
of resistanL-e wires, This formula was used in working
out the experimental result. The test specimens were
Card 1/3 wire-wound resistors type NS-414. All the variables that
enter into expression (9) were determined, The main

dimensions of the resistance elements axe given in Table I
and Fig 1 which also shows the positions of th.e thermo-
couples used. The elements used were mad,~i of constantan
wire. A number of different arrangemints wrere tested,
horizonta17 vertical, various arrangerrients of
bundles and boxes, and the test results are given In
Fig 2. An empirical relationship between tfte lrariables
for horizontally arranged elements _Js given in fformnla
(10), and for vertically arranged elements in foi-mula (11).
These formulae give results that differ from experimental
values by not more than 3%, A correction factor is given
that must be used if the resistance wire is of' some
material other than constantan. Equations 1,10) and (11),
which are based on many exparimental results, clan be used
either directly for thermal calculations on wiae-wound
resistances or for the formulation of tables.

on the power but also on the wire diameter, the winding
pitch and particularly on the design of the entire
resistAnce element. The formulae derived are then used
for consideration of the most economical design of resis-
tance elements. It is shown that if the elements are
arranged vertically much more active material is required
than if they are arranged horizontally. Table 2 gives
.values of resistance and permissible currents for
standard elements and for elements with revised pitch.
In both cases the permissible currents are calculated for
single row open boxes using expression (10). The results
Card 3/3 show that the pitch of the elements should be increased.

~of mqnufaeture; 4) reduction In,mounting and repair times; 5) a
Ireduction In dimensions of the body of the working wheel. The
'four stainless steel blades are rotated by a servo-mechanism In

COVERAM: The collection contains papers read at a seminar on cutting-tool
materials organized and sponsored by the ftmissiyu po tekhnologii mashinostroy-
eniya (Commission on Processing in Machine Building). The seminar investigated
the cutting properties of ceramic and carbide tool materials, the effect of
temperature on 'cutting edges,, the problem of wear,, and the possibility of
using cutting tools more efficiently. No personalities are mentioned.
