Show 1 I THE LAST FRONTIER FRONTIERA 1 I trI 3 2 j a aA L A REMARKABLE MACHINE WHICH SORTS CIGARS ACCORDING TO THEIR COLOR SCIENCE HAS DEVELOPED AN AUTOMATIC EYE By DAVID DIETZ NEA Service Writer The pioneers of f the last frontier the frontier of science i expect to solve the labor problem for the world some da daThe day The They expect to do it by abol abol- abolishing labor laborThe The scientist looks upon every necessary mechanical task as one which can be bo performed eventual- eventual eventually ly by the proper sort of automatic I machinery Auto and tractors constitute au au- au- au automatic feet feel Derricks and cranes aro are automatic hands Dozens of delicate machines might be classed as II autom i 1 finers Now the tho scientist bas ban added an automatic eye to the tho list The photo photo electric electric cell does the trick This consists of some sonic metal like selenium which allows an elec elec- electric trio trie current to flow through it only when light strikes It ft The stronger stroner the light the more current it lets through The latest application of the photo photo electric electric cell is in an automatic auto auto- automatic automatic matic cigar sorter perfected by in mentors in Brooklyn N JC Y The apparatus automatically picks up cigars holds them up to Its mechanical eo eye the photo photoelectric electric elE cell and sorts them Into I one of thirty compartments on a aI circular table according to the I shade of brown of the tho cigar The shade of the tho cigar of course determines the tho nature of the light which falls on the photo electric cell This in turn determines the tho strength of an electric current which operates oper tes a motor system for distributing tho the cigars The Tho machine sorts accurately 60 clears clars a n one a set sound id which is a higher rate of speed than can bo ho maintained by human sorters The chemist Is slowly making progress In the field of synthetic foods At the present time he he finds it possible to make synthetic fats that are edible and Just as nutritious as the fats found in nature He lIe is not only able ablo to duplicate fats fits and oils which exist ex lilt In nature but b t he can even make ones that thit never ne existed before In the case of the tho fats found In I nature each molecule always alwa's con conn contains contains an even number of carbor atoms The chemist can cm make mako fats in the tho the laboratory that contain either cither an au odd or an even eu number of carbon molecules A prize of known as the Metz prize has bas been blen offered to the tho chemist who devises a means of making synthetic morphine A number ot oI methods of oC making cocaine synthetically have been worked out In Europe Citric Curie acid the tho acid found In lemons sal ammoniac and formal formal- formaldehyde are three of tho the substances used in tho the making of the syn syn- synthetic synthetic tic the cocaine It is believed that the discovery of synthetic morphine would result in the wiping out of the opium crop of India since sin co this crop would no longer be needed |
