APPARATUS FOB BEGENEBATING AIR. I

To all whom t may concern.'

Be it `known that I, GEORGE voN SCRAP- RINGER, a subject ofthe Emperor of Austria-Hungary, residing at Vienna, Austria- Hungary, have invented certain new and useful Improvements'in Regenerating Air, of which the following is a specification.

In rooms or chambers intended for thev inhalation of radium .emanations it is of importance to regenerate the spent air exhaled by the patients and to render it again respirable. In accordance with the present invention, this regeneration of the spent breathing air is obtained by means of an apparatus which is mounted in such rooms or chambers, takes up the exhaled air, cools the same in a refrigerating device and then lforces it through a medium that absorbs .the carbonic dioxid, whereupon the thus regenerated air is allowed to be discharged` v again in the room or chamber.

The apparatus consists essentially of a box or receptacle that is connected on the one side with an exhauster 0r the like and on the other side with-the emanation chamber and comprises a cooling device and an absorption chamber separated from the latter by affiltering layer.

In the accompanying drawings Figure 1 yshows a side elevation of an apparatus according to the present invention, Fig. 2 is a vertical cross section on the line A-B of Fig. l and Fig. 3 is a plan-thereof with the top plate removed.

On the base platea is mounted a box b' subdivided by two horizontal partitions c, d into three superposed cells or compartments. The lowermost compartment f lined on all sides by perforated metal sheets e contains an electromotor la mounted on a pedestal g and an exhauster i or similar suction device for exhausting the air, driven by the said electromotor. The disgharge tube j' of the exhauster opens by means of an aperture in the partition c into the second box-compartment la which is closed on all sides. Within this compartment lo is arranged kt-he ribbed refrigerator or cooler .l through the pipes of which flows the cooling medium. The spent air forced into this compartment 7c by the exhauster flows along .the outer surface of the ribs of the refrigerator and becomes cooled. In\ order to maintain the air in intimate contact with the cooling pipes and the rlbs of the refrig- Specication of Letters ltatent.

erator, delecting surfaces m may be fitted at suitable places within the compartment lc between the coolingy pipes l.

compartment lc at the topconsists of two metal platesv d d which are arranged at a certain distance apart and are provided with perforations and between which is interposed a ilterin cloth d2. The spent air, which has been orced 'into the compartment k and has been cooled therein,' but which is not yet regenerated, passes through the perforations of the metallic plates d d and the filtering cloth d2 into Athe next higher compartmentn of the box. This walls g g into three' separate sections o, p, o the arrangement `being such lthat the cooled air, coming from the compartment -c enters only into the two exterior sections 0, o of the compartment ma The middle section p is intended for holding the receptacles r which contain and furnish the emanation means, whereas the two exterior sections o o are provided with receptacles .s which are made vof perforated metal plates or of wire cloth bent so as to form a U-shaped cross section `and which are filled with a material capable of absorbing carbon dioxid, such as soda-lime or caustic potash. Each of the sections o, o is subdivided by the partitions t into separate cells u and'in each cell u is suspended-a receptacle s in such a manner as to enter with its lower end into a funnel-shaped space m separated from the adjacent spaces by means of the inclined roof-shaped strips fv (Fig. 2). Theaper- 'tures provided in the top-plate d of the partition wall d open into the said spaces w. The entire apparatus is closed at the top by -means of two perforated metallic plates e e arranged at a certain distance apart and having a ltering cloth z2 placed between the same.r The spentair that has been cooled in the compartment c and has been freed of impurities by its passage through the filtering layer d2 flows now through the absorbing mediumcontained in the receptacle s and 1sA thus freed from carbon dioxid. It then passes through the upper filtering layer e2 where it is entirely `freed from dust whereupon it returns again as clear respirL able air into the room or chamber in which the inhalation of the emanation means takes The horizontall partition d which closes the compartment is subdivided by the partition l 4with absorbing material capable of absorbing the carbon-dioxid in the exhaled air,

andan air filter, closing the apparatus at the top and forming a communication between the compartment containing the absorption device and the surrounding atmosphere.
