Clipper is the brand name of a type of refillable butane lighter, designed by Enric Sardà and owned by Flamagas S.A. [1] since 1959. The lighters are mostly produced in Barcelona, with others manufactured in Chennai and Shanghai. [2] Clipper has a wide range of lighters, gas refills and other accessories.
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
In principle, the lightest element that can be analysed is beryllium (Z = 4), but due to instrumental limitations and low X-ray yields for the light elements, it is often difficult to quantify elements lighter than sodium (Z = 11), unless background corrections and very comprehensive inter-element corrections are made.

Circular and U-shaped lamps were devised to reduce the length of fluorescent light fixtures. The first fluorescent light bulb and fixture were displayed to the general public at the 1939 New York World's Fair. The spiral CFL was invented in 1976 by Edward E. Hammer, an engineer with General Electric, [7] in response to the 1973 oil crisis. [8]
Cold-cathode lamps include cold-cathode fluorescent lamps (CCFLs) and neon lamps.Neon lamps primarily rely on excitation of gas molecules to emit light; CCFLs use a discharge in mercury vapor to develop ultraviolet light, which in turn causes a fluorescent coating on the inside of the lamp to emit visible light.
This layer also reflects the phosphor light to the desired direction, and protects the phosphor from ion bombardment resulting from an imperfect vacuum. To reduce the image degradation by reflection of ambient light, contrast can be increased by several methods. In addition to black masking of unused areas of screen, the phosphor particles in ...
Z – Vacuum full-wave rectifier (dual power diode with common cathode) Following digits: model number and base type For signal pentodes, an odd model number most often identified a variable-mu (remote- cutoff ) tube, whereas an even number identified a 'high slope' (sharp-cutoff) tube
