     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 16 illustrate an improved jalousie 18, comprising a casing 20 built in a wall 22 of a building 24. A structural framework 26 is in the casing 20, while a louver 28 fits into the structural framework 26. A component 30, best seen in FIG. 11, is for tilting the louver 28 inwardly in the structural framework 26. The louver 28 can be removed from the structural framework 26, to be cleaned and replaced when needed. 
     The improved jalousie 10 further includes an element 32, for sliding the louver 28 in the structural framework 26, as best seen in FIG. 11. The louver 28 contains a sash 34. A plurality of slats 36 are positioned within the sash 34 in horizontal adjustable parallel arrangements, to regulate the passage of air into the building 24 for ventilation purposes. 
     Each slat 36 is a thin narrow flat rectangular strip 38. Each thin narrow flat rectangular strip 38 is fabricated out of a transparent material 40, to allow light to enter into the building 24. The transparent material 40 is glass. 
     The tilting component 30 is a hinge member 42 on a bottom rail 43 of the sash 34, to allow the sash 34 to tilt forward into the building 24 from the structural framework 26. The sliding element 32 is a track 44 built into the structural framework 26, to allow the hinge member 42 on the bottom rail 43 of the sash 26 to ride within the track 44. 
     A plurality of weather strips 46 are provided. Each weather strip 46 is between the abutting edges of the slats 36, to insulate when the slats 36 are closed during cold weather conditions, as shown in FIG. 11. 
     A pair of latch mechanisms 48 are also provided. Each latch mechanism 48 has a manually operable lock handle 50. Each latch mechanism 48 is located in a side jamb 52 of the casing 20. The lock handle 50 extends through an inner face 54 of the side jamb 52 of the casing 20. When the latch mechanisms 48 are placed in locked positions by the manual operation of the lock handles 50, the structural framework 26 with the louver 28 will be maintained in an upright position in the casing 20. (See FIGS. 6, 7, 8 and 11.) 
     The structural framework 26, as shown in FIGS. 1 through 12, is a window 54. The structural framework 26, in FIGS. 13 through 16 is a door 56. 
     Screens 58 can be used, as shown in FIG. 5. The screens 58 will cover the louvers 28, which can be opened in warm weather for ventilation. The screens 58 can slide and be removed into the building 24. The screens 58 can also pocket into the wall 2, if the casing 20 is so constructed to the wall 22. 
     In the windows 54, the louvers 28 can slide back and fourth in the track 44, as shown in FIGS. 1, 2, 4, 5, 10 and 12. The louvers 28 can slide up and down in the track 44, as shown in FIGS. 3 and 9. The louvers 28 are stationary in FIGS. 6, 7, 8 and 11. 
     In the doors 56, the louvers 28 are stationary, as shown in FIGS. 13 and 14. The louvers 28 can slide back and fourth in the track 44 in FIGS. 15 and 16. 
     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. 
     While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. 
     Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
