A louver is a window, blind or shuttes with horizontal or, less often, vertical slats, that are angled to admit light and air, but to keep out rain, direct sunshine, and noise. The angle of the slats may be adjustable, usual in blinds and windows, or fixed.
This patent is about a tower made by LARGE and SMALL louvers.
In a combined large and small bore syringe, the small bore syringe is used as the plunger for the large bore syringe. Movement of the small bore syringe plunger produces a high pressure, low volume flow while subsequent movement of the entirety of the small bore syringe as the plunger of the large bore syringe produces a low pressure, high volume liquid flow.
