GERMAN INVENTORS
RENEW ACTIVITIES
Patents Range From New
Anesthetics and DyestuffS
to Modern Pig Sly.

The German chemist once more is
coming to the front.
Distorted into a sinister figure dur
Ing the war and his patents seized by
the allied nations, he has renewed his
researches into the structure of matter
and flood of patentable formulas for
synthetic dyes and medicines is coming
forth from his laboratories
Among the 3,l76 patents issued in
Washington last week German inventors
have prominent place with formulas
ranging from new anaesthetic to new
dye stuffs. The anesthetic, described
as an animo-benzoic acid product,
diethyl animoethanal, was patented by
Walter Schoeller and Hans Georg
Allardt of Berlin. Other chemical
patents issued, besides those for dye
stufts were for a process OF INTRODUCING
Sulphoanic groups into organic COM
pounds and for Classifying and distilling
solid fuel. Still another was for an
acid-resisting wrapping material.
But not all the German inventors are
concerned with organic chemistry,
where they have won their greatest
triumphs. William Lodge of Pader-
born received q patent for a pig-sty,
with dining room and bed chambers
Tor the hogs in addition to space for
the less aesthetic activities which are
most conspicuous in ordinary pigpens.
It apparently is intended to enable
young pigs to be reared for the slaughter
In more refined atmosphere, with
separate compartments for rearing
with sleeping and feeding rooms"
Invention Aids Campers.
Erich Fabrianke of Berlin is con-
cerned with improving the lot of camp
ers with means of lighting tents with
electricity. This consists of a dry bat
terry arrangement incorporated in the
center pole of the tent. Thus the elec-
trio light plant becomes part of the
tent itself and the camper need never
be without this adjunct of civilization
wherever he stops for the night.
Inventions for the week covered a
wide range, from new types of television
apparatus and a means of telephony
over power lines to eyelaShes for dolls
which can be bent naturally SO as to
give the doll a more lifelike appear
ance, and an egg opener patented by a
Californian designed as a valuable ad-
dition to the housewives kitchen kit
The latter consists of a pistol-like ar
rangement operated with trigger. the
egg being contained in a receptacle at
the end and the shell cut away with
knives.
Another curious patent was for
''water skates'-"elongated waterproof
tanks pointed in front and square be-
nlno, Wnlch can be fastened on the
foot and with which presumably the
person with appropriate skill can
skate" over the surface.
Flying Device Patented.
The old dream of the "bird-man"
soaring through the air with his own
wing apparently is not satisfied with
the airplane, the dirigible or the glider.
and inventors constantly are trying to
get back closer to the model of Icarus
Such a device was patented this week
by Emile Laurent of Paris, "a flying
apparatus comprising in combination a
cuirass to be fixed on the body to cover
the back and the head, propeller, two
movable lateral planes Of angle, the in
clination of which may be altered at
will. means for operating by hand said
lateral planes, two lateral, stationary,
supporting planes, two supporting tur-
bines with eccentric extensible blades.
and a motor with oval base arranged on
said cuirass and driving turbines and
propeller"
It seems to be something like an air
plane without a fuSelage or rather with
the body of the aviator to which the
wings are attached forming the fuselage
A man Tugs his motor through the air
on his back and flies with it.
