patent was issued to DR.. Lee De
Forest. inventor of the radio tube, for
a method of producing positive film
with both sound and picture records
thereon The method consists in eX-
posing the picture area of the positive
film to the picture record on the mega
tive. longitudinally displscing the posi-
tive and negative films relatively to
each other, and then exposing the sound
area of the positive to the sound area
Of the negative. This, according to the
description, produces positive film
having sound and picture records, sepa-
rated a predetermined distance.
Anthony H. G. Fokker, the aircraft
inventor, associated with Alfred H. Gass-
ner of New York. received patents on
two amphibian airplane devices which
can be controlled by the pilot so that
he can land on water or land as he
plesses.
The first is described as IAN airplane
Of amphibian type, comprising hull,
wings associated Herewith, means con-
nected with the hull and variably ad-
iusted relatively thereto for imparting
the water. wheels for supporting the
airplane from the ground, means con-
Meeting said wheels to the wings, and
said means yieldable in response to
landing impacts, and movable means OF
communication between the lateral sta
bilizing means and the wheels"
Built as Amphibian.
The second is IAN amphibian airplane
embodying an undercarriage structure
for supporting the craft when on the
ground, including float disposed on
each side of the hull of the airplane.
means rigidly connecting to said hull
below the wings, and to each float for
maintaining the latter in fixed rela-
tionship to the hull, and lateral bracing
means rotatably connected with the
hull and floats the wheels or floats to
be used at the option of the operator"
The patent for the cigarette pocket

Evanston, Ill. 1t is intended to be just
the right size so a standard package OF
cigarettes will fit in 1t Snugly, with
tapering edges to the closure flap so
that the feminine smoker can draw out

invented by Pedro Torrabadella OF
Argentina.
The transmitting apparatus consists
of "a light sensitive cell having
plurality of cells sensitive to different
variations in the intensity of light and
adapted to be varied by the passage OF
light through images brought into its
vicinity each of said cells being con-
nected in circuit with the primary OF
transformer, tuning fork having pre-
determined frequency and source OF
supply. each of said transformers nav
ing their secondaries connected in
zones with an amplifier, an antenna
connected to said amplifler whereby
upon the change of intensity of light
upon said light sensitive cells the diff
ferent vibrations CT the tuning forks
induces different impulses into the sec
ondaries of said transformers.
The receiving apparatus comprises an
smplifier connected with an antenna
for receiving the waves of the trans
hitting apparatus, relay in circuit
with the amplifier. a plurality of tuned
reeds having frequencies corresponding
to the freQuencies of the tuning forks
and the transmitting apparatus con-
nected in circuit with the relay through
q corresponding number of transform
ers and a source of supply, each OF the
reeds being connected to corresponding
light cells in a light sensitive. cell, a.
The light is adapted to cast light rays
through the cell, whereby the picture
transmitted is reproduced on the screen

The apparatus for utilizing solar heat
vas patented by Charles H. Drane Of
Del Ray, Fla. 1t consists of glass
topped heat collecting chamber to be
exposed to the sun rays, a heat ex-
changer, a closed gas circulating sys-
tenn, including a coil in the heat COL
lector, a coil in the heat exchanger
and a compressor for COMPRISING hot
gas from the heat collector and deliver
ing it to the heat exchanger; means for
delivering water to the heat exchanger;
a pump for delivering pre-heated water
to the exchanger. and a float In the
ezchanger electrically controlling the
