Robert Henry "Bob" Gurr (born October 25, 1931 in Los Angeles, California) is an American amusement ride designer and Imagineer.
 His most famous work was for Walt Disney's Disneyland Park, and its subsequent sister parks.
 Gurr is said to have designed most, if not all, of the ride vehicles of the Disneyland attractions, including Autopia, Haunted Mansion, the Disneyland Monorail, the Submarine Voyage, and the Matterhorn Bobsleds.
 He was named a Disney Legend in 2004.
 He also worked on the King Kong Encounter animatronic for Universal Studios Hollywood.
A rail yard, railway yard or railroad yard is the US term for a complex series of railroad tracks for storing, sorting, or loading/unloading, railroad cars and/or locomotives.
 Railroad yards have many tracks in parallel for keeping rolling stock stored off the mainline, so that they do not obstruct the flow of traffic.
 Railroad cars are moved around by specially designed yard switchers, a type of locomotive.
 Cars in a railroad yard may be sorted by numerous categories, including railroad company, loaded or unloaded, destination, car type, or whether they need repairs.
 Railroad yards are normally built where there is a need to store cars while they are not being loaded or unloaded, or are waiting to be assembled into trains.
 Large yards may have a tower to control operations.
This is a list of windows on Main Street, U.S.A. at the Disney resorts.
 The names painted in the windows serve as credits for some of the many people who contributed in some manner to the parks (Disneyland Paris being an exception, where some refer to characters or stories from Disney films and shows).
 Typically they appear as fictional businesses (realtors, dentists, etc.), and often refer to a hobby of or development made by the person honored.
 Bob Gurr's window, for example, refers to his development of most vehicles at the park.
Chute dogging is a rodeo event related to steer wrestling, in which the steer used weighs between 400 and .
 However, the competitor starts the event in a roping chute with the steer as opposed to grabbing onto the steer from horseback.
 The event is designed to give novices a chance to prepare for steer wrestling.
The Mark IV monorail was a design model of straddle-type monorail trains.
 The design was developed by legendary Disney Imagineer Bob Gurr.
 Ten trains were built by Martin Marietta in 1969 at the cost of about $7 million USD each and they were used on the Walt Disney World Monorail System between 1971 and 1989 before they were replaced by the Mark VI monorail, although a few lasted until 1991.
 Sometime between 1991 and 1994 Monorail Coral and Lime (which had been introduced new in 1984) were sold for $3.5 million each, refurbished, and used to begin the Las Vegas Monorail operations.
 In 2004 Lime and Coral (now the MGM and Bally) were replaced by fully automated Bombardier MVI 4-car trains.
Chevrolet "Corvair Powerglide" is a two-speed automatic transmission designed specially for the then all-new 1960 Chevrolet Corvair compact car that emerged in the fall of 1959 as Chevrolet's competitor in the then booming small car market.
 The Corvair was powered by a six-cylinder rear engine that necessitated a specially designed transaxle.
 Corvair Powerglide took the principles of the standard Chevrolet Powerglide and modified them to suit the rear-mounted powertrain location of the new Corvair.
 The Corvair used the Powerglide for all 10 years it was produced; from 1961 to 1963, Pontiac used a modified version of Corvair Powerglide it called 'TempesTorque' for its front-engine, rear-transaxle Tempest, LeMans and Tempest LeMans cars.
Autopia is a Disneyland attraction, in which patrons steer specially designed cars through an enclosed track.
 Versions of Autopia exist at Anaheim, California and Disneyland Paris in Marne-la-Vallée, France.
 There was also an Autopia at Hong Kong Disneyland on Lantau Island, Hong Kong before it closed on June 11, 2016.
 Other versions of the attraction can be found at the Magic Kingdom as the Tomorrowland Speedway and formerly at Tokyo Disneyland as the Grand Circuit Raceway.
The Omnimover is an amusement ride system used for Disney theme park attractions.
 Roger Broggie and Bert Brundage developed the system for WED Enterprises, which patented Omnimover in April 1968.
 The term was coined by Imagineer Bob Gurr and is a portmanteau of OmniRange and PeopleMover.
 Outside of Disney, it is known as an Endless Transit System.
A bulk carrier, bulk freighter, or bulker is a merchant ship specially designed to transport unpackaged bulk cargo, such as grains, coal, ore, and cement in its cargo holds.
 Since the first specialized bulk carrier was built in 1852, economic forces have fuelled the development of these ships, causing them to grow in size and sophistication.
 Today's bulkers are specially designed to maximize capacity, safety, efficiency, and durability.
Cadence braking or stutter braking is a driving technique that involves pumping the brake pedal and is used to allow a car to both steer and brake on a slippery surface.
 It is used to effect an emergency stop where traction is limited to reduce the effect of skidding from road wheels locking up under braking.
 This can be a particular problem when different tires have different traction, such as on patchy ice for example.
 Its use in an emergency requires a presence of mind that the situation itself might preclude.
 Cadence braking is supposed to maximize the time for the driver to steer around the obstacle ahead, as it allows the driver to steer while slowing.
 It needs to be learned and practiced.
 For most drivers of modern cars, it has been entirely superseded by ABS, however it is still a valuable skill for drivers of non-ABS equipped vehicles such as classic cars or economy cars.
