3 Claims.

The object of my invention is to provide a new method for heating and/or maintaining proper temperature levels of solutions or fluids used as therapeutic agents, stimulants, foods or tonics administered subcutaneously, intravenously through a needle or other device attached to the end of a tube, or intrarectally or other organs of the body through a rubber tube or any other kind of tube usually employed in the adminisi tration of such fluids, solutions or drugs.

I attain these and other objects of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a view partly in side elevation and i5 partly in longitudinal section of a part of my invention;

Fig. 2 is an end elevation at the outlet end of the device;

Fig. 3 is an end elevation at the inlet end of {En the device;

Fig. 4 is a vertical section on line 4-4 of Fig. 1; Fig. 5 is a diagrammatic view of the electric circuit used;

Fig. 6 is a view, partly in elevation, partly in 3.". longitudinal and partly with only a portion of the shell broken away to show the interior contruction of one form of my invention;

Fig. 7 is a transverse section on approximately line of Fig. 6; and :1", Fig. 8 is a diagrammatic view of the electric wiring for this form of the invention.

Like numerals designate like parts in each of the several views.

Referring to the drawings, l indicates any conl i provideplates 2 of insulation maiiigl tion as supports forheater coils 3. Mounted onplates 2 is a semi-cylindrical plate or shelf on which I mount a tube or other suitable container 1:") 5.Container 5 has a suitable end plate 6 (which may be removable if desired) and the inlet tube I4. I provide a suitable thermostat and thermostatic casing for same designated 1 and mounted in anend plate 6 as shown in Fig. l. I also pro- 43 vide a suitable removableend closure plate 8 at the outlet end of the container. I provide suitableencircling reinforcing plates 9 to reinforce thecontainer 5 at the end portions thereof, as shown in Fig. l.

50 I provide an outlet tube I mountedn closure plate 8 and an inlet tube l4 mounted inclosure plate 8. Inlet tube M may be connected with a faucet or provided with a conventional valve not claimed as a part of this invention. 0n out- 55 let tube ill I provide a valve casing l i in which a valve I2 is mounted, having a threaded portion mounted in the threaded seat at l3. This plate is held in place by thethumb screws 24 ofclosure member 8, as shown in Fig. 2.Plate 8 is preferably slightly bevelled at 26 to a seat tightly in the end oftube 5. Referring to Fig. 5 illustrating the electric circuit, thenumeral 15 designates a current wire from which the wire it leads to theheater coils 3 which in turn are electrically connected with the armature switch ll of the relay ill. I provide a wire l9 leading from member I! to the secondcurrent wire 20. I provide awire 2| from current wire 29 to therelay 3 and awire 22 from the relay If! to the thermostat l and awire 23 from thethermostat 1 to the current wire l8.

As will be understood by referring to Fig. 5 the thermostat may be adjusted to make and break the electric current at the particular temperature desired and thereby control the operation of therelay 1 8 to operate the armature or switch I! and thus connect or dis-connect the electric coils from the electric switch and thereby control their operation and thereby automatically regulate the operation of theheater 25 coils and thus the temperature of the liquid within thecontainer 5. The heater coils may be of any desired length and position to secure a uniform temperature of the fluid throughout the tube; or at the inlet end; or at the outlet end as desired.

For successful use of an instrument of this character it is necessary (a) that solutions must be sterile and kept sterile; (b) that the solutions should be heated to the proper temperature (apnin n iiiiii n. n innn the blood stream or under the skin at tha temperature; and (c) that the apparatus for heating solutions, i. e., the containers, should be detachable for sterilizing.

By actual tests solutions flowing through tubes in small quantities and at a slow rate lose approximately 2 degrees for each inch of tube through which the solution flows. My apparatus not only heats the solution to a predetermined temperature but delivers it at this temperature into the vein by means of the attachment represented in Fig. 6. This has been proven by placing a thermometer in the flow pipe near the needle where it can be observed. 0

As will be understood by referring to Fig. 2 of the drawings, theenclosure plate 8 may readily be removed by removing thethumb screws 24 or disengaging the slottedears 25 from saidthumb screws 24.

using ordinary salt, sodium chloride, it is preferred to use the phosphorus pentoxide in the glazing of those wares which are diflicult, or practically impossible to glaze, by the use of ordinary salt, such as wares which have a high lime or high alumina content. Such wares may be glazed by the use of phosphorus pentoxide alone or after a preliminary salt glaze produced in the usual manner. In some instances the phosphorus pentoxide glazing may be followed by a final salt glazing.

The gaseous mixture containing phosphorus pentoxide and suitable for glazing with the material may be obtained by any convenient means, such as, by the partial or total oxidation 01 phosphate reduction furnace gas, by the oxidation of elemental phosphorus 'or by the volatilization of phosphorus pentoxide. The amount of the phosphorus pentoxide required will depend upon the composition and the surface or the were to be glazed. The operation of a 30 foot down-draft sewer pipe kiln given below will serve to further indicate the method of operation a and the amounts of glazing materials required. One round of salt means to lbs. of sodium chloride, distributed equally to each fire box and oneround of phosphorus pentoxide means 25 to 100 lbs. of phosphorus pentoxide, or its equivalent, distributed equally to each fire box. The ware to be glazed is placed in the kiln, brought to the proper temperature for salt glazing and contacted with a gaseous mixture containing the active glazing agent in any one of the sequences outlined as follows:

1. One or more rounds o! phosphorus pentoxide.

2. One or more rounds of phosphorus pentoxide, and one or more rounds of sodium chloride.

3. One or more rounds of sodium chloride, and one or more rounds of phosphorus pentoxide.

4. One or more rounds oi sodium chloride, one or more rounds of phosphorus pentoxide and one or more rounds of sodium chloride.

The kiln is operated throughout in substantially the same manner currently used in the salt glazing operation and after the final glazing operation the kiln is cooled in the usual manner.

It will be seen, therefore, that this invention actually may be carried out by the modification of certain details without departing from its spirit or scope.

I claim:

1. Process for making glazed ceramic ware,

which comprises, burning a phosphate reduction furnace gas to form a gaseous mixture containing phosphorus pentoxide, and contacting a glazed ceramic ware with the gaseous mixture containing phosphorus pentoxide, while maintaining the ware at a glazing temperature.

2. Process for making glazed ceramic ware, which comprises, burning elemental phosphorus to form a gaseous mixture containing phosphorus pentoxide, and contacting an unglazed ceramic were with the gaseous mixture containing phosphorus pentoxide, while maintaining the were at a glazing temperature.

3. Process for making glazed ceramic ware, which comprises, contacting an unglazed ceramic ware with a gaseous mixture containing sodium chloride, while maintaining the ware at a,

glazing temperature; and contacting the salt glazed ceramic were with a gaseous mixture containing phosphorus pentoxide, while maintaining the were at a glazing temperature.

4. Process for making glazed ceramic ware,

5. Process for making glazed ceramic ware,

which comprises, contacting a glazed ceramic ware with a gaseous mixture containing phosphorus pentoxide, while maintaining the ware at a glazing temperature.

6. Process for making glazed ceramic ware, which comprises, contacting a ceramic ware with a gaseous mixture containing phosphorus pentoxide, while maintaining the ware at a glazing temperature.

7. A glazed ceramic ware, consistirig of, an

unglazed ceramic ware which has been glazed with salt and phosphorus pentoxide.

8. A glazed ceramic ware, consisting oi, a glazed ceramic ware which has been finally glazed with phosphorus pentoxide.
