Stooky Bill
Stooky Bill was the name given to the head of a ventriloquist's dummy that Scottish television pioneer John Logie Baird used in his 1924 experiments to transmit a televised image between rooms in his laboratory at 22 Frith Street, London. History John Logie Baird invented some of the first experimental television systems. In 1924 he developed a mechanical television system to transmit moving images by means of electrical signals, which he demonstrated on 25 March 1925 at a London department store, Selfridges. It consisted of a spinning disk set with a spiral pattern of 30 lenses. As each lens rotated past the illuminated subject, it focused the light from a spot on the subject on a selenium photoelectric cell. This converted the brightness of the image at each spot into a proportional electric signal, which could be sent to a receiver by radio waves. As each lens swept past the subject, it scanned a successive line of the image. At the receiver, a light shining through t ...

Stucco
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture. Stucco can be applied on construction materials such as metal, expanded metal lath, concrete, cinder block, or clay brick and adobe for decorative and structural purposes. In English, "stucco" sometimes refers to a coating for the outside of a building and " plaster" to a coating for interiors. As described below, however, the materials themselves often have little or no difference. Other European languages, notably Italian, do not have the same distinction: ''stucco'' means ''plaster'' in Italian and serves for both. Composition The basic composition of stucco is lime, water, and sand. The difference in nomenclature between stucco, plaster, and mortar is based more on use than composition. ...

Phonovision
Phonovision was a patented concept to create pre-recorded mechanically scanned television recordings on gramophone records. Attempts at developing Phonovision were undertaken in the late 1920s in London by its inventor, Scottish television pioneer John Logie Baird. The objective was not simply to record video, but to record it synchronously, as Baird intended playback from an inexpensive playback device, which he called a 'Phonovisor'. Baird stated that he had several records made of the sound of the vision signal but that the quality was poor. Unlike Baird's other experiments (including stereoscopy, colour and infra-red night-vision), there is no evidence of him having demonstrated playback of pictures, though he did play back the sound of the vision signal to audiences. Baird moved on leaving behind several discs in the hands of museums and favoured company members. Until 1982, this was the extent of knowledge regarding Phonovision. Discoveries and restoration From 1982, Donald ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Television
The concept of television is the work of many individuals in the late 19th and early 20th centuries. Constantin Perskyi had coined the word ''television'' in a paper read to the International Electricity Congress at the Exposition Universelle (1900), World's Fair in Paris on August 24, 1900. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass medium for advertising, propagand ...

Mechanical Television
Mechanical television or mechanical scan television is an obsolete television system that relies on a mechanism (engineering), mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode-ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) and LED displays are now used to create and display television pictures. Mechanical scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by Scottish inventor John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Doctor Who Villains
Over the course of its many years on television, the long-running British science fiction television series ''Doctor Who'' has not only seen changes in the actors to play the Doctor, but in the supporting cast as well. Companions The Doctor is usually accompanied in his travels by one to three companions (sometimes called assistants). These characters provide a surrogate with whom the audience can identify, and further the story by asking questions and getting into trouble, (similar to Dr. Watson in the Sherlock Holmes mysteries.) The Doctor regularly gains new companions and loses old ones; sometimes they return home, or find new causes on worlds they have visited. A few of the companions have died during the course of the series. Recurring characters UNIT personnel * Brigadier Sir Alistair Gordon Lethbridge-Stewart ( Nicholas Courtney) * Kate Lethbridge-Stewart ( Beverley Cressman, Jemma Redgrave) *Colonel Christofer Ibrahim (Alexander Devrient) * Captain Mike Yates ( ...

Orthopedic Cast
An orthopedic cast, commonly referred to simply as a cast, is a form of medical treatment used to immobilize and support bones and soft tissues during the healing process after fractures, surgeries, or severe injuries. By restricting movement, casts provide stability to the affected area, enabling proper alignment and healing of bones, ligaments, and tendons. They are commonly applied to the limbs but can also be used for the trunk, neck, or other parts of the body in specific cases. Orthopedic casts come in various types and designs, tailored to the nature and severity of the injury, as well as the patient's needs. Advances in medical techniques have made casts more comfortable, effective, and versatile, allowing for both weight-bearing and non-weight-bearing options. Upper extremity casts Upper extremity casts are frequently utilized to immobilize the arm, wrist, or hand for the treatment of fractures, soft tissue injuries, or during post-surgical recovery. They offer stabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plaster Of Paris
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum, lime, or cement,Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily worked with metal tools and sandpaper and can be moulded, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
