Tenax I
The Tenax I is a 24x24 mm fixed lens camera by Zeiss Ikon launched in 1939. The Tenax I was actually launched after the Tenax II. Like the Tenax II, it is a 24×24mm square-format camera taking over 50 exposures on a standard 135 film (35 mm), with a rapid-advance lever next to the lens. But it is a much simpler camera, with a completely different body, no rangefinder, a simple folding viewfinder on the top plate, and a ''Compur'' leaf shutter In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow ... to 1/300". Most of them are equipped with a Zeiss Novar 3.5 cm f/3.5 lens. A smaller number have a Carl Zeiss Jena 3.5 cm f/2.8 Tessar. Production began in 1938, and it was nearly halted in 1941. There was limited production during the rest of the war. After the war, the Ea ...

Tenax II
During the 1930s, Zeiss Ikon (ZI) made a wide range of miniature cameras for the '' 35mm film'' format. Most cameras used the standard 24×36 mm frame size, like the ''Contax'', ''Nettax'' and ''Super Nettel''. However, the ability to take images in fast sequence was a popular marketing element at the time, and several fast-operating models were made. Among these were the Otto Berning's motor-driven ''Robot'' cameras as well as the ZI lever-operated ''Tenax I'' and ''Tenax II''. These have the smaller square format of 24×24 mm, enhancing faster frame advance. The Tenax II is a ''35mm'' RF-camera launched by ZI in 1938. It produces 50 square exposures on a standard length of ''35mm film''. It has a ''Compur Rapid'' shutter, situated just behind the lens, with speeds from 1 to 1/400 second. The camera is wound and the film advanced simultaneously depressing the large lever on the right-hand side of the lens. At first it was only called the ''Tenax'', but the following ...

Poly(2,6-diphenylphenylene Oxide)
Poly(2,6-diphenyl-p-phenylene oxide) (PPPO) is a porous polymer resin based on oxidative polymerisation of 2,6-diphenylphenol. It is mostly known by its trademark Tenax. Properties Poly(2,6-diphenylphenylene oxide) is a low bleeding material with a low level of impurities, and has a high thermal stability (up to 350 °C). Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components. During conditioning or thermal desorption the presence of oxygen should be avoided. Poly(2,6-diphenylphenylene oxide) reacts with oxidising agents such as chlorine, ozone, nitrogen oxides and sulfur oxides forming acetophenone, benzaldehyde and phenol. Therefore, control of blanks is essential and storage time of samples on poly(2,6-diphenylphenylene oxide) is less than a month. Pre-filters based on sodium thiosulphate or Teflon may be appropriate to use. The breakthrough volumes are low for very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phormium Tenax
''Phormium tenax'' (called flax in New Zealand English; in Māori language, Māori; New Zealand flax outside New Zealand; and New Zealand hemp in historical nautical contexts) is an evergreen perennial plant native to New Zealand and Norfolk Island that is an important fiber, fibre plant and a popular ornamental plant.Roger Holmes and Lance Walheim. 2005. ''California Home Landscaping'', Creative Homeowner Press The plant grows as a clump of long, straplike leaves, up to two metres long, from which arises a much taller flowering shoot, with dramatic yellow or red flowers. Despite being commonly known as 'flax', harakeke is of the genus ''Phormium'', a monocot, and is a leaf fibre, whereas flax (linen) is of the genus ''Linum'', a rosid, and is a bast fibre (which comes from the stem of the plant). The two plants have an evolutionary extremely distant relationship with each other. The fibre has been widely used since the arrival of Māori people, Māori to New Zealand, origin ...
