Feriodicea t Stan. J instr,j 3; 1 - 5, Mar 1934
Abstract t Ijigh-speed grinding is introduced to industrY. Three methods of high-
sp,ced uinding are described. The first method consists in increasing
the speed of the grinding wheel -without changing other grinding factors.
The second method is based mainly on maintaining the pressure, stabil-
ized at the level used in reEular grinding, The third method consists
in increasing the speed of the grinding wheel and the cutting depth.
A detailed analysis of straightening truncated grinding wheels is also
given. Graphs; diagrams

to determine contact resistance of conduit couplings
and bushings. Tests were made under laboratory
conditions.with various types of connections, and then
under operational conditons. Possibilities of using
conduits for gMunding and as neutrals were
Investigated. It was found that the best contacts
are 3btained with properly made tightly connected pipe
threods, Conduits can be used in grounding, but not

Title t 1rotection from electric shook by wy of Frotective disconnection
Periodical : Energetikv 8. 32-35v Ag 1955
Abstract i Replying to inquiries of many readers,, the author describes the
details of "protective disconnection!' which can be used in industrial
establAshments instead of grounding of electrical equipment. The
essential of such protection consists in an arrangement which
immediately disconnects the protected object as soon an a specified
voltage appears on its casing. The advantage of this system con-
sists in the fact that such protection operates mwh quicker than
grounding. The author describes three types of "protective
disconnootiorP and presents formulas for their calculationg according
to the degree of protection required. One table, 3 connection
diagrams.

Abstract : The authors study the problem of Influence of resist-

capacity with jecondary windings 380/220 and 220/12T V.
and a star-st&r connection upon the impedance of the

problem of disconnecting a faulty sector. The authoza
present a method of calculating the current of a

For practical purposes they present a simplified
