APPARATUS WITH CIRCUITS OSCILLATING
UNDER MULTIPLE WAVE LENGTHS
Georges Lakhovsky, Paris, France
Application November 13, 1931, Serial No. 574,907
In France Mav 2, 1931
7 Claims. (Cl. 250-33)
The present invention has for its object an apparatus capable of
sending out simultaneously different wave lengths so that among these
waves or their harmonics there is found almost always one or several
capable of producing the best effect sought for any application whatever.
There is used for that purpose the property of open circuits having
a fundamental or natural self induction and capacity to oscillate upon a
well determined wave length if they are excited by electric impulses
emanating from discharges of any source.
The radiating part of the system, producing waves of various
lengths, is therefore constituted by a certain number of concentric open
rings of different diameters, which are maintained insulated by any
appropriate means. These rings may or may not be terminated by small
spheres forming capacities.
These rings may be arranged either in the same plane or in different
planes so as to form any surfaces, such as portions of cones, spheres,
paraboloids, ellipsoids, etc. ..., these surfaces being of a nature to
concentrate the waves in a determined direction in the manner of a
reflector, for example.
These rings may be fed by any producing device whatever of high
frequency, for example, a combination comprising a trembler coil (or any
other transformer) and a high frequency circuit provided with a
self-induction coil and a capacity.
One or several points of this high frequency circuit is or are
connected to the end of one or several of the rings forming the radiating
apparatus. The other rings not connected are excited by induction.
The complete apparatus (coil, high frequency circuits, rings,
etc. ...), may be mounted in a box or upon a small board capable of
sliding along a guide or rocking so as to be able to be placed in the
most convenient position.
In the accompanying drawing, by way of example, not limitative,
there is shown:
Fig. 1 a diagram of the system.
Fig. 2 the position of the rings in the form of a cone.
Fig. 3 the apparatus mounted upon a foot or base.
In Fig. 1 there is seen at T the transformer or coil (P the primary,
S the secondary of this coil), V, the screw of the trembler, C the
condenser the discharge of which across the spark gap E produces
oscillations in the self-induction coil L1, which in its turn acts by
induction upon the self-induction coil L2; this self-induction coil L2
is connected on one side to the first exterior ring "a", on the other side
to the following ring "b". It thus forms an electrostatic field of high
frequency which induces oscillations in the other rings "c", "d", "e", "f".
As a modification, L2 may be suppressed and the rings "a" and "b"
may be connected each to one of the ends of L1.
One of the ends, or even any point of the self-induction coils L1 or
L2 may likewise be connected to any one of the rings.
Fig. 2 shows the arrangement of the rings in the form of a cone.
The open circuits "a", "b", "c", ..., "f" can be constituted by solid
conductors. They can also be tubular circuits, this being advantageous,
since, for the same bulk, the radiating surface is larger. Finally, the area
of the cross section of each of these various circuits can vary from one
circuit to the other for instance, this area can decrease from the periphery
(ring "a") to the center (ring "f") of the radiating system.
Figs 3 shows the apparatus mounted upon a foot A along which it can
slide, in order to be placed at any desired height and upon a hinge B
which allows it to be oriented upon the horizon.
