This invention relates to the control of mov
and 24, and two condensers 25 and 26. The sec
ondaries of the transformers 23 and 24 are con
nected in the filament circuits of two space dis
ing bodies from a distance, and more particularly
to a new and improved means for preventing re
spOnse in this control from other than the de
charge devices 21 and 28, and also by wires 50, Si
sired source.
to two resistances 28 and 30 and by wires t2, it
to the grids of two space discharge devices 3i and
32. The output circuits of these devices include
a double solenoid consisting of two windings 33
and 34 connected to the anodes of tubes 3i and
32 by wires 84 and 65, respectively, and two bat
teries 35 and 36. The point between these bat
teries is connected to the plates and grids of the
devices 21 and 28 by wire 86.
The double solenoid 23 and 34 is provided with
a central magnetic core 38, one end of which is
secured to the stem of a valve 4I which is mount
ed for reciprocation in a valve casing 42. SeM
cured to the stem of the valve 4I are two collars
43 and 44, between which and the casing 42 are
two spiral springs 45 and 46. The valve casing
42 is provided with three ports 41, 48, and 49
which communicate with a source of fluid under
pressure 5I, and the two ends of a cylinder 52 re~spectively. The cylinder 52 is provided with a
piston 53 which is normally held in a central po
sition by means of two spiral springs 54 and 55.
The piston 53 is connected by a piston rod 56 to

'I'he invention relates particularly to a selective
receiving system for radiant energy which is
adapted to control the movement of a torpedo
after it has been launched. The steering means
of the torpedo is rendered operative in response 10
to radiant impulses transmitted from a distance
and selectively effects the deviation of the tor
pedo to port or starboard or maintains the steer
ing means in a central position.
The invention further provides a selective sys 15
tem of radio control which is dependent in its
operation upon the use of two high frequency sig
nais or a single high frequency modulated at two
low frequencies. These signals operate the system
so that when one is received the torpedo will be 20
caused to steer to the left, and when the other
is received it will be steered to the right.
The invention also consists in certain new and
original features of construction and combina
tions of parts hereinafter set forth and claimed.

to be characteristic of this invention will be par

direction, thus steering the torpedo to starboard.
It is thus seen that when a 205,000 cycle wave is
sent, the torpedo will be steered to port and will
continue to turn in this direction as long as this
signal is transmitted. At the termination of this
signal, the torpedo will then proceed on the course
on which it is headed at that time. If a 203,500

starboard and will continue to so turn until the
termination of this impulse.
The other method of operation is by the use
