Horizontal Venetian Blinds

horizontal venetian blinds

    venetian blinds
  • A window blind consisting of horizontal slats that can be pivoted to control the amount of light that passes through it

  • A hanging blind with slats that are held together by strips of webbing or ribbon

  • A window blind is a type of window covering which is made with slats of fabric, wood, plastic or metal that adjust by rotating from an open position to a closed position by allowing slats to overlap. A roller blind does not have slats but comprises a single piece of material.

  • Blinds constructed of horizontal strips of wood, aluminium or PVC, Gives a modern look to home or office and a large degree of light control

  • parallel to or in the plane of the horizon or a base line; "a horizontal surface"

  • something that is oriented horizontally

  • (horizontally) in a horizontal direction; "a gallery quite often is added to make use of space vertically as well as horizontally"

  • A horizontal line, plane, etc

This study examines the effects of the presence of a Venetian blind on the thermal performance of a window. The blind is positioned adjacent to the indoor surface of either a single or double glazed window and the coupled convection and radiation heat transfer problem is solved using a two-dimensional finite volume model. The numerical model is validated with published experimental and numerical results in the literature. The results show that the presence of a Venetian blind significantly improves the energy performance of a single and double glazed window. The blind reduces the overall heat transfer rate through the window by reducing the thermal radiation from the indoor glazing. The improved understanding of the benefits of Venetian blinds may lead to better designs of window/shading systems.

Kino Eye

Kino Eye

An attempt, although not a very successful one, to use my "Lens in a Cap" to shoot through the viewfinder of my old Soviet Konvas, which is perhaps my favorite filmmaking tool. Presented here for reference only, as all artistic merit seems to have fallen by the wayside.

The Konvas has an interesting viewfinder in that it has horizontal shutters running across the image in the viewfinder. There aren't wires, either. These are like venetian blinds. They're probably an eighth of an inch deep. They're apparently supposed to keep stray light from fogging the film during exposure. When I first started to use the Konvas it was very difficult to ignore them, but in time I got so I didn't even really notice them anymore.

You'll notice the complete lack of information in the viewfinder. No crop lines. No exposure information. Nothing. Very simple. This camera has no electronics whatsoever. If you have a DC motor hooked up to it there's that, but in this hand-cranked configuration there are literally no electronics at all. I find that extremely comforting for some reason.

About JET: A History of Sharing New, Feature-Rich Products
Opened in 1958 after the founder of the company, Leslie P. Sussman, took the first Boeing Jet Airplane trip from Seattle, Washington to Japan, JET began as a small dealer that sold air hoists and trolleys out of a single hardware store in Seattle. Over the years, JET has carried everything from snowmobiles, transmitter radios, and forklifts to nylon stockings, but by the early 1970s, metalworking had become the base of their business line. And by the 1980s, JET had expanded into the realm of woodworking. Today, you'll find that JET offers a wide range of popular woodworking tools that are backed with best-in-class features and excellent service.
