Patents Reveal Future
Items of Convenience
Washington Science Serv
ice) The landing space re
quired by the Jet aircraft of
the future may be less, thanks
to a means of reversing the
direction of thrust of a Jet en
gine just patented here.
This Invention won one of
the 976 patents granted Inst
week, for Edgar P. Peregrine
of Royston, Eng., who as
signed it to Bristol Aero En
gines Ltd.
The device consists of a
valve which closes off the
duct through which the Jet
Eases pass and channels them
around to provide a thrust In
the onnosite direction. The
valve consists of two (or
more) segments which open
and close like the beuk of a
bird so that, when open, they
fit flush with the walls of the
duct, and, when closed, they
seal off the duct completely.
Points Upstream '
The "beak" points up
stream so that the pressure of
the Jet holds It closed. The

closing of the valve uncovers
side ducts, previously sealed
off by the valve segments,
through which the jet stream
is deflected. At the same time
corresponding sections swing
out from the outside surface
of the plane to complete the
side ducts so that the jets are
now directed back in the di
rection of the plane's motion
to provide a braking effect.
A vertically collapsible
trailer to be towed behind a
car also won a patent.
The inventor, Vilas L, Sny
der of Wichita, Knns., ex
plains that his mobile home
may be expanded when used
for "sleeping or cooking or
any other purpose for which
trailer houses arc designed,"
and may be contracted for
travel for less wind resist
ance, less obstruction to vis
Ion, a lower center of gravity,
and greater stability.
Sections Raised, Lowered
The trailer Is made In three
vertically telescoping sections
which are raised or lowered
by means of a cable and pul
ley system operating through
a winch.
Also patented this week
were an improved baseball
bat, a flip-top cigarette box
with a built-in ash receptacle
and a multiple smoke signal
unit.
Clarence L. Paullus, Colum
bus, Ohio, points out that
baseball bats often chip and
split after prolonged use. A
player often has to discard
his bat just when he has be
come well used to it.
Invents Bat
To prevent this chipping,
Paullus has invented a bat In
which a series of strips of
very hard wood are let into
the striking surface of the bat
so as to be parallel to the
length of the bat and perpen
dicular to the layering of the
wood. The patent was as
signed to Hillerich and Brads-
by company, Louisville, Ky
There will be no excuse for
getting cigarette ash on the
carpet should some forward-
looking manufacturer adopt
the idea of Clyde A., Richard
O., and Donald G. Peel of
Spring Lake, Mich. They have
designed a flip-top box in
which the side also flips out
to form an ash receptacle.
Another form of smoking Is
the subject of a patent issued
to Bruce E. Del Mar, Los An.
geles, and assigned to Del Mar
Engineering Laboratories Inc.,
also of Los Angeles, The in
vention is a multiple smoke
signal an airborne smoke
bomb that contains a number
of smoke captures which may
be set to be released in a pre
determined sequence as mili
tary signals.
Other Inventions
Other inventions patented
here this week include a side
mounted rear view mirror
with an automatic wiper for
trucks, a means of coating mo
vie screens with lead carbo
nate crystals to give brighter
pictures, a hair drying cap
knitted with covered heating
element which plugs into the
electric circuit, and an under
water camera husing which,
the Inventor claims, maybe
adapted so as to fit virtually
any 33mm camera.
Firefighters Delay
Action by Council
Portland-fllPD - Objections
from the Portland Firefighters
association Wednesday delay
ed city council action on send
ing several proposed city
charter changes to the voters.
The proposed changes are
intended to "modernize" sev
eral chapters of the charter,
including a chapter on the fire
and police fund,
Harry Williams, represent
ing the Firefighters Associa
tion, said the proposed re
visions would result in "mark
edly changing some benefits."
New Bridge Forces
Store To Close
Portland - WPD - W. E. Rob
erts, chairman of the board of
Roberts Bros., said today that
the firm's department store at
S.W. Third and Morrison here
will be discontinued, probably
next month.
Roberts said the new Mor
rison Street bridge has chang
ed traffic patterns in down
town Portland and "has made
the location less desirable as a
retail outlet."
Roberts said the closure
would not affect other Rob
erts Bros, stores, like Lip
man's In Portland, Salem and
Corvallls.
NO JOB TOO SMALL
New York - An 11-yoar-old
who wanted a football jersey
but didn't have the money to
buy it decided to try a bank.
William Sicari went to the
Manufacturers Trust compa
ny, pledged his bicycle and
his electric trains as security
and floated a $5 loan. The
terms were that ho pay $1.02
each month for five months.

Fort Knox, Ky. HOT - U. S.
Army tankem are lighting

Amid the realistically aim

armored battles are waged
dally on a miniature battle

The amall-scalo battle area
la complete with mountain!,
rivers, foresta, buildings and
other features tha't might be
encountered under actual
combat conditions. Two cur
tains divide the "battlefield"
Into the approximate distance
a platoon leader might be
able to see If he were actually
engaging an enemy.
The tank Dlatoon IpaHor onH

in compartments on a mov

board. The platoon leader'i
commands are transmitted by

A tank crew nnrmnllv mn.

training exercise because the
tanka are electronically fired.
At the other enri nl th.

P'atoon leaders are scored .
on the methods by which they
attempt solution of the tacti

on wnai u considered tne best

After each battle Is con
