Light tubes (also known as solar pipes, tubular skylights or sun tunnels [1]) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides. In their application to daylighting, they are also often called tubular daylighting devices, sun pipes, sun scopes, or ...
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
Renovation work at East High School was completed in December 2008. The work included restoring numerous skylights throughout the building, refinishing the solid woodwork and wrought iron railings, as well as installing energy-efficient lighting fixtures. The new capacity is 1032 students.
CNC plasma cutting Plasma cutting performed by an industrial robot Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma . Typical materials cut with a plasma torch include steel , stainless steel , aluminum , brass and copper , although other conductive metals may be cut as ...
The name of this area derives from Lucas Sullivant, who was first deeded this land.For a time the area was known as Sullivant’s Hill and as time went on, the ownership of the land was transferred and the name was changed to the Hilltop.
A retractable skylight rolls (on a set of tracks) off the frame, so that the interior of the facility is entirely open to the outdoors, i.e., not impeded by a hinged skylight. The terms retractable skylight and retractable roof are often used interchangeably, though skylight implies a degree of transparency. Tubular daylight device
Because of declining enrollment in the school district and deterioration of the building, Central High School permanently closed following the 1981–1982 school year, in June 1982. After the closure, Central High School was used as a shooting location for scenes in the 1984 film Teachers, depicting the fictional "John F. Kennedy High School".
Arc-based cutting methods are used for cutting these materials. Among these, plasma arc cutting is the most commonly employed technique, owing to its precision and ability to cut through high-alloy steels efficiently. [1] Thermal cutting creates a shallow region contaminated material adjacent to the cut surfaces - the heat affected zone. For ...
