Baffle Ball is a pinball machine created in 1931 by Gottlieb . It was the first pinball machine, and was designed by company founder David Gottlieb. It cost a penny to play and gave players seven balls to shoot into scoring holes. It spawned a home version in 1932 called Baffle Ball Senior. ref http www.nokia.com A4136002?newsid 1000426 Nokia Celebrates 75 Years Of Pinball With New Screenshots For Mile High Pinball from Nokia ref References reflist Baffle Ball was responsible for the launch of the company Gottlieb that went on to make pinballs such as Ace High and Black Hole. It used no electricity and for 1 cent, players got 5 balls. They would be fired up onto the playfield and fell into pockets and holes there were no flippers . Some were worth more than others, and players tried to fire the ball at just the right speed. The best thing to get was the Baffle Ball, which was getting the ball into a tiny hole at the top. It would double all points All scoring had to be done by hand. It would sit atop bar counters and the bar tender may award payouts for high scores. It seems rather basic now among all of these electronic flipper pinballs nowadays, but it was well ahead of its time. It is very popular with collectors and is very sought after.

orphan date March 2010 Unreferenced date March 2009 A squirrel baffle is a device designed to deter squirrel s, raccoon s and other small mammal s from accessing birdfeeder s to retrieve birdseed . They are typically mounted on the pole of a birdfeeder, and most effectively at least four feet from the ground, as squirrels can jump rather high. Squirrel baffles vary in design. One type may employ a rotating cylinder to destabilize the climbing surface, while another will feature a large round tube difficult for a squirrel to grab onto. Other designs include tapered cones and sloped disks. Many squirrel baffles are made of painted metal or plastic, in order to create a slippery surface. The roof of a hanging birdfeeder can also be designed to act as a baffle to prevent squirrels from jumping down onto the feeder. Providing an alternate equivalent food source in conjunction with a squirrel baffle is often the best way to minimize unwanted visits to a birdfeeder. There are many squirrel feeders available, as they love to eat all sorts of food.

Unreferenced date December 2009 A sound baffle is a construction or device which reduces the strength level not the intensity of airborne sound . Sound baffles are a fundamental tool of noise mitigation , the practice of minimizing noise pollution or reverberation . An important type of sound baffle is the noise barrier constructed along highways to reduce sound levels at properties in the vicinity. Sound baffles are also applied to walls and ceilings in building interiors to absorption acoustics absorb sound energy and thus lessen reverberation . Highway noise barriers Main Noise barrier The technology for accurate prediction of the effects of noise barrier design using a computer model to analyze roadway noise has been available since the early 1970s. The earliest published scientific design of a noise barrier may have occurred in Santa Clara County , California in 1970 for a section of the Foothill Expressway in Los Altos, California . The county used a computer model to predict the effects of sound propagation from roadways , with variables consisting of vehicle speed , ratio of trucks to automobiles, road surface type, roadway geometric s, micro meteorology and the design of proposed soundwalls . Interior sound baffle design Main Architectural acoustics Since the early 1900s scientists have been aware of the utility of certain types of interior coatings or baffles to improve the acoustics of concert halls , theaters , conference rooms and other spaces where the quality of sound is important. By the mid 1950s Bolt, Beranek and Newman and a few other U.S. research organizations were developing technology to address the design challenges. This design field draws on several disciplines including acoustical science , computer modeling, architecture and materials science .

Image bafflespray.jpg thumb right 275px Figure 1 Baffle spray scrubber Baffle spray scrubbers are a technology for air pollution control . They are very similar to spray tower s in design and operation. However, in addition to using the energy provided by the spray nozzles, baffle s are added to allow the gas stream to atomize some liquid as it passes over them. A simple baffle scrubber system is shown in Figure 1 . Liquid sprays capture pollutant s and also remove collected particles from the baffles. Adding baffles slightly increases the pressure drop of the system. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubber s. A number of wet scrubber designs use energy from both the gas stream and liquid stream to collect pollutants. Many of these combination devices are available commercially. A seemingly unending number of scrubber designs have been developed by changing system geometry and incorporating vanes, nozzles, and baffles. Particle collection These devices are used much the same as spray tower s to preclean or remove particles larger than 10 m in diameter. However, they will tend to plug or corrode if particle concentration of the exhaust gas stream is high. Gas collection Even though these devices are not specifically used for gas collection, they are capable of a small amount of gas absorption chemistry absorption because of their large wetted surface. Summary These devices are most commonly used as precleaners to remove large particles 10 m in diameter . The pressure drop s across baffle scrubbers are usually low, but so are the collection efficiencies. Maintenance problems are minimal. The main problem is the buildup of solids on the baffles. br Table 1 summarizes the operating characteristics of baffle spray scrubbers. ref http www.epa.gov apti US EPA Air Pollution Training Institute developed ... characteristics of baffle spray scrubbers align center width 12 Pollutant align center Pressure ... more details

For the engine component, see Rocker cover Context date October 2009 A rocker box also known as a cradle is a mining implement for separating alluvial placer gold from sand and gravel. It consists of a high sided box, which is open on one end and on top. ref http www.icmj2.com BegCorner USGSHowToMineForGold.htm 8517h10 West, J.M. 1971. How to Mine and Prospect for Placer Gold. Information Circular 8517, Bureau of Mines. Accessed April 19, 2012 ref The inside bottom of the box is lined with riffles and a usually a carpet similar to a sluice . On top of the box is a classifier sieve usually with half inch or quarter inch openings which screens out larger pieces of rock and other material, allowing only finer sand and gravel through. Between the sieve and the lower sluice section is a baffle, which acts as another trap for fine gold and also ensures that the aggregate material being processed is evenly distributed before it enters the sluice section. It sits at an angle and points towards the closed back of the box. Traditionally, the baffle consisted of a flexible apron or blanket riffle made of canvas or a similar material, which had a sag of about an inch and a half in the center, to act as a collection pocket for fine gold. Later rockers including most modern ones dispensed with the flexible apron and used a pair of solid wood or metal baffle boards which. These are sometimes covered with carpet to trap fine gold. The entire device sits on rockers at a slight gradient, which allows it to be rocked side to side. Today, the rocker box is not used as extensively as the sluice , but still is an effective method of recovering gold in areas where there is not enough available water to operate a sluice effectively. Like a sluice box, the rocker box has riffle s and a carpet in it to trap the gold. It was designed to be used in areas with less water than a sluice box. The process involves pouring water out of a small cup and then rocking the small sluice box like a cradle ... more details

Three variants of the mine exist one with magenetic influence fuze, one with a self extending tilt rod fuze, and another with a contact baffle. Upon ejection from its container, the mine deploys a small parachute which retards its descent. The three prong legs of the mine form a spike as the mine descends. If the mine strikes soft ground, the spike is driven into the ground and the mine is held upright. In addition the mine has an anti handling device .
