I-ABSMkCT: A laboratory vacuum furnace for heating, melting, zon
evaporating (for yacuum-vapor deposition) primarily refractory metals has been
designed and built at an unidentified institution. The furnace operates with several
heating systems (resistance, radiation,' arc, and electron beam)used individuallypr
in combination. The vacuum chamber can be evacuated to a pressure of 10-6 mm Hg,
The furnace produces ingots,50 mm in 'diameter and up to 400 mm long. The charge
can be placed in advance or fed durtng the melting. Zone refining can. be done
eposi-
iwith a metal-bar in thehorizontal or vertical position. In vacuum-vapor d
tion, the evaporation is done with an electron beam, and the temperature of the
substrate is controlled with radiant heat. The furnace has two 45-kw electron guns
operating with an.accelerating volta e 6f*30 kv. Orii. art. has: l.figure.

ABSTRACT.: A study was made of the effect of horizontal and vertical accelerations an
the roadings of a pendulum-type gravity meter, mounted on an ideal gyrostabilized plat-..
form in an ideal universal joint. The resulting cross-coupling affect was analyzed
theoretically, the parameters being related by the differential equation:

ABSTRAM In the investigation of plans stationary flows,.it is
convenient to use the hodograph plane. In Ref 2 and 3
were constructed the characteristic manifolds in this
plane and in RifA shock poiari were constructed for
flows with parallelfield and velocity vectors. These-
shock polars were obtained from the conditions of
conservation of.mass, impulse and energy of the flow and:,
-increase of entropy. Those regimes from the above are,'
found which arestable in accordance with stability-
conditions which are quoted from Ref 1. Some consideration
leads to support forthe opinion that fast shock waves are --L
always stable. In the range of Mach number investigated,-
fast shock waves satisfy the stability conditions. @ It is
