Why What Is Billiards Is A Tactic Not A method > 자유게시판

And most bulb bases are still compatible with the standard incandescent bulbs we all grew up with. Although triacetate does not decompose in as dangerous a way as nitrate does, it is still subject to a process known as deacetylation, often nicknamed "vinegar syndrome" (due to the acetic acid smell of decomposing film) by archivists, which causes the film to shrink, deform, become brittle and eventually unusable. In the American game, roqueting a ball out of bounds or running a hoop so that the ball goes out of bounds causes the turn to end, and balls that go out of bounds are replaced only nine inches (23 cm) from the boundary rather than one yard (91 cm) as in association croquet. There are seven solid-colored balls numbered 1 through 7, seven striped balls numbered 9 through 15, an 8 ball, and a cue ball. If an attempt is made to pocket a ball, and the ball hits the pocket, bounces out and lands on the ground, the ball is placed in the pocket and the game continues.

Balls must be played in order (for the primary ball colours, this is blue, red, black, and yellow), and this order of play is maintained throughout the game. You must be able to determine your finish and start point for using this purpose. Most automobile "touch up" paints are still made from lacquer because of its fast drying, easy application, and superior adhesion properties - regardless of the material used for the original finish. Nitrocellulose film base manufactured by Kodak can be identified by the presence of the word "nitrate" in dark letters along one edge; the word only in clear letters on a dark background indicates derivation from a nitrate base original negative or projection print, but the film in hand itself may be a later print or copy negative, made on safety film. Projection rooms may also be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium. The use of volatile nitrocellulose film for motion pictures led many cinemas to fireproof their projection rooms with wall coverings made of asbestos.

BD usually arrives in subscribers' mailboxes, at the newsstands and on the counters of finer billiard shops and rooms by the week before the issue date (i.e., the November issue would arrive around Oct. 24). However, because of postal inconsistencies, issues will sometimes arrive somewhat late, sometimes up to a full week. Also, polyester film is so strong, it will not break under tension and may cause serious damage to expensive camera or projector mechanisms in the event of a film jam, whereas triacetate film breaks easily, reducing the risk of damage. Later that same month, many more reels and film cans of negatives and prints also burned at Edison Studios in New York City, in the Bronx; then again, on May 13, a fire at Universal Pictures' Colonial Hall "film factory" in Manhattan consumed another extensive collection. Yet again, on June 13 in Philadelphia, a fire and a series of explosions ignited inside the 186-square-meter (2,000-square-foot) film vault of the Lubin Manufacturing Company and quickly wiped out virtually all of that studio's pre-1914 catalogue. Acetate film manufactured during the era when nitrate films were still in use was marked "Safety" or "Safety Film" along one edge in dark letters.

Commercial production started in 1891, but the result was flammable and more expensive than cellulose acetate or cuprammonium rayon. Related fires in other medical facilities prompted the growing disuse of nitrocellulose stock for X-rays by 1933, nearly two decades before its use was discontinued for motion-picture films in favour of cellulose acetate film, what is billiards more commonly known as "safety film". Cinema fires caused by the ignition of nitrocellulose film stock commonly occurred as well. That fire, a catastrophic one, started inside a film-inspection building and caused over $7,000,000 in property damages ($213,000,000 today). In the meantime, George Eastman had already started production of roll-film using his own process. Triacetate remains in use for most camera negative stocks because it can be "invisibly" spliced using solvents during negative assembly, while polyester film is usually spliced using adhesive tape patches, which leave visible marks in the frame area. This was used commercially as "celluloid", a highly flammable plastic that until the mid-20th century formed the basis for lacquers and photographic film. Disastrous fires related to celluloid or "nitrate film" became regular occurrences in the motion picture industry throughout the silent era and for many years after the arrival of sound film. The film was also used for many years in the field of medicine, where its hazardous nature was most acute, especially in its application to X-ray photography.
