Show FOR THE HOT SEASON A cathl mathene which turn turns out a glau glass of 1 I sod soda for a tenth of is cent A portable apparatus lias has recently been constructed by which soda water canborg can boro be reduced in cost from twelve cents to three centa cents a gallon it has las three cylinder cylinders respectively for gas gus water and prepared eoda soda water the gas cylinder which holds twenty two pounds of liquefied carbonic acid Is narrow but enormously strong being capable of resisting a pressure of pound pounds to tho the square inch without bursting when empty it can be taken apart from the rest of the machine and ree recharged barged where the carbonic acid gas cas is condensed charged cylinder cylinders may also be obtained from the natural gas wells on the banks of the rhino in europe tho the middle cylinder is made like an ordinary hot water reservoir and holds about sixty gallons of croton water it withstands a pressure of ISO pounds to the square inch the Tho third cylinder Is simply an ordinary sod coda water awater drum such as may inny bo be seen about store stores where aerated w waters are sold on draught drought the process proem of a liquefying or solidifying carbonic acid gas Is coming becoming ah austry many volumes of the gas are pumped into ft small chamber which is kept under ie a freezing mixture until condensation and liquefaction ia is produced until lately it his ha been used cheuy tor for adding gas to lager beer and for causing intense cold iu iii tho the laboratory but fresh uses are being constantly fit found for it chemists who manufacture their own soda water prepare this gas from marble dast which is a carbonate of lime and i sulphuric acid add the gas Is thou forced under pr pressure mare into a cylinder containing water which is then rolled about until the gas cas and water are thoroughly mixed when tho the carbonated water constitutes tho the soda water of commerce many chemists have aban abandoned donod this process pro cese and get their soda water ready made from the wholesale who losalo manufacturer by the new now process a cylinder of li liquefied quelled carbonic tar bonic acid gas is capable of turning out gallons of eoda soda water tho the gas passes paws from the first cylinder into a small chamber where the pressure which Is required tor for the remainder of the manufacture ii I 1 regulated it Is about seventy fib pounds to the square inch the gas Is then divided into two streams I 1 one being admitted into of t the he second or water cylinder while the other pas passes into a chamber through several injector Joc tors A pi ppe pe runs from the bottom of the water cylinder to tois tills chambermaid chamber and as the gnu gria rushes through the line flue nozzles of the in rectors it draws the water with it past a valve valto the gas and water at aie a by this time mixed mime 1 but in order that they may become co completely in so 0 o it small turbine wheel obstructs their course in such a way that theyan tb eyan thoroughly incorporated after passing ith it the third cylinder Is connected with the eoda soda water fountain in the usual way vitty TV two gauge gauges are added to the apparatus to show the amount of abo pressures in making ng soda water by this method the cost 0 f at cent glass Is about one ten tenth th of a cent ne new v york bun sun |
