APPARATUS FOR GENERATINIGYRADIUM TER- Applicati on filed February This invention relates to an improved apparatus for generating radium water and has as its. primary object to provide an apparatus by the employment of which, water, introduced into the apparatus, may become impregnated with radium emanations from the radium-bearing material within the apparatus, to a maximum degree. It is a well known fact that radium emanations contained in water will be rapidly dissipated unless the impregnated water is maintained under pressure. Even under this condition, the emanations will be discharged from the water and be condensed or deposited on the surfaces of the container which are above the water level. Therefore, it is obvious that if these deposited emanations can be again returned to the water, impregnation ofthe water to a maximum degree will be eflected, and the present invention contemplates the provision of an apparatus where by this result may be obtained.

Another object of the inventlon 1s to provide an apparatus for generating radium water so constructed and capable of operation in such a manner as to permit ofrecovery of a maximum amount of the emanations which have escaped from the water within the container of the apparatus and which have condensed or accumulated upon the walls of the container above the water 'level,.so that the apparatus will possess maximum efficiency and a thoroughly impregnated fluid ma be obtained therefrom. Another object o the invention is to provide a novel and highly eflicient radiumemanation bearing unit or medium which will insure of thorough impregnation of the water within the container of the apparatus. I

Another object of the invention is to so construct theradium-emanation bearing unit or medium and the portion of the apparatus with which it is associated, that the said unit may be removed and another unit substituted therefor, thus permitting of the emloyment, in the apparatus, of radium-bearing materials of different strengths.

Figure 5 is a fragmentary sectional view illustrating a slight modification of the invention. Y

The apparatus embodying the invention includes a container which is indicated in general by the numeral 1 and which is supported upon a stand indicated in general by the numeral 2 and comprising a base 3'and spaced upstanding uprights 4, the container being provided with trunnions 5 and 6 uponits outer side located at diametrically opposite points and nearer one end of the container than the other, the said trunnionsbeing journaled in bearing openings in the upper ends of the uprights 4; Inasmuch as the trunnions 5 and 6 are located nearer oneend of the container than the other and which end will be considered, in the following description, as the upper end, the container will be overbalanced' and tend to normally assume the position shown in Figure 2 of the drawings. In order that the container may be swung back and forth upon its trunnions and completely rotated, a crank handle 7 is secured to the projecting endof the trunnion 6, and the purpose of thus imparting motion to the container will presently be fully explained. It may be stated at this point that when the container assumes the position shown inFigure 2, it is inwhat may be termed the generating position and when it is inverted as shown in Figurel, it is in position for the delivery therefmmof the impregnated water, and in order that the container may be held in this latter position while the impregnated water is being drawn therefrom, the wall. of'the container is preferably for-med, opposite one of the uprights i, with a boss 8 having a socket 9 therein to accommodate the end of v a locking plunger 10 which is slidably fitted' through the said upright and which is yieldably held, by a coil spring 11, thereon, in position to engage in the said socket 9, the outer end of the plunger being provided with a finger piece 12 whereby it may be re tracted to permit of return of thecontainer to generating position. A faucet13 of any ordinary type is secured in' an air-tight manner in the wall of the container near the said upper end thereof and, when the container is in the deliveringposition shown in Figure 1 of the drawings, is so positioned as to permit of water being drawn from the container into a glass.

The container 1 may be of metal or any other material found suitable for the purpose and the same is of cylindrical form and comprises a, cylindrical wall 13, an upper end wall 14, and a bottom 15, and the con tainer is preferablyinitially formed intwo sections threaded together as at 16, a gasket 16' being'arranged at the threaded connection to render the same air-tight. A lining 17 of porous material such as porcelaimmay be'applied to the inner surface of the upper section, including the cylindrical wall portion of said section as well as the top or upper end wall 14,and by separating the sec tions, the lining may be cleaned as required.

It has been found that porous material of this nature will more readily accumulate and retain the emanations which are deposited thereon than will a non-porous surface and, therefore, inasmuch as, in the generating position of the container shown in Fi ure .2, the portion of the container which 1s provided with the lining 17 is above the level of the water within the container, the radium emanations which. escape from the water during the process of generation, will be deposited upon the surface of the saidlining and retained thereby.

The numeral 18 indicates in" general a unit which carries the radio-active material and this unit comprises a metal base 19 :which is of flat circular form and threaded at its periphery as at 20 to engage threads upon the wall ofan opening 21 formed in the bottom 15 of the container and located centrally of said bottom. The underside of the base 19 is preferably formed with a diametric groove 22'for the application of a screw driver whereby the base may be water within the container. The numeral shown in Figure 4 of the drawings. At this point it will be evident that radio-active units bearingradio-active material of difbe readily substituted ferent strengths may he cylinder 24 is, of

course, open at its top so that water introduced into the container will fill the cylinder aswell as surround the same and, when the container is in the enerating position shown in Figure 2 of tfi e drawings, the radium emanations will impregnate the water with- I in the-containerand these emanations will be dissipated and deposited upon the lming ,17. Inasmuch the container is closed in an air-tight manner during the period of gen- T eration, none of the emanations w1ll escape to the atmosphere.- 1 In order that water may be introduced into the container of the apparatus, the top wall 14 of the containeris provided with an interiorly threaded neck 26 into which is removably threaded a closure plug27,a packing gasket 28 being preferably interposedbetween the upper end of the neck and the underside of the head of the said plug so as, to provide an air-tight fit between the parts.

The numeral 29 indicates in general "a pressure check valve which may be of any ofthe well known types and which is "secured in an opening in the top wall 14 of I the container in an air-tight manner and provides means whereby carbonic acid gas or 1111; under pressure, or carbonated water,

may be introduced into the container, primarily to establish pressure within the container but also for the purpose of either carbonating the water within the container or aerating the same.

In the use of the apparatus, the container I 1 being in the position shown in Figure 2, i

the closure plug 27 is removedand, the valve or faucet 13 being open, water is introduced into the contalner until it appearsat-the said faucet, whereupon the faucet is closed and. the plug 27 is replaced. Carbon dioxide gas,

carbonated water, or air, under pressure, is then introduced into the container by way of the check valve 29 until the desired pressure has been established in the container, and c:

this maybe determined by an ordinary pressure gage applied, to the valve. The container is then permitted to remain in the position shown in Figure 2, for a suflicient tions from the radio-active material 25 within the cylinder 24, after whichthe container length. of, time to permit the water to become'impregnated with the radium emanais rocked or swung backwardly and forwardly through the'medium of the crank handle7, or the cont-ainermaybe so swung tion, may be completely rotated several times through the medium of the crank handle so as to cause the water within the container to wash or surge over the lining 17 and effect further impregnation of the water with the radium emanations. It will be understood that where carbonic acid gas is introduced under pressure into the container, the agitation of the water in the container resulting from the previously described move ment of the container, will effect absorption of the gas by the water, and whether the gas referred to or air is introduced under pressure, the efiect will be to disturb the radio-active material of the unit 18 and force the radium emanations into the water. Likewise, when the container is rocked or revolved, the radium emanations which have been deposited on the wall of the container will be taken up by the water.

When it is desired to withdraw the radium impregnated water from the container, the container is rotated to the position shown in Figure 1 of the drawings, and the faucet 13' may then be opened to permit of the discharge of the water, it being understood that the pressure which has been established within the container serves to effect delivery of the water without the necessity of the provision of any vent opening in the con tainer.

The lining 17 is a permanent lining and it will, of course, be desirable to introduce into the container of the apparatus filtered water so that there will be no likelihood of the accumulation of impurities upon the surface of the lining.

Figure 5 of the drawings illustrates a slightmodification of the invention in which the sections of the container may be connected by threads 30 or in any other manner, and a continuous bead 31 of solder applied to the outer side of the container to extend entirely around and close the joint between the sections in a gas-tight manner, it being understood that by scraping off the bead 31, the sections may be readily separated.
