This expression, typically used to mean ‘the real thing’. But none of the other cups worked as well as his, so customers started asking for "the real McCoy." That's where the expression comes from. Ahrons' Lubrication of Locomotives (1922), which does identify several other early pioneers and companies of the field. Other inventors tried to copy McCoy's oil-dripping cup. Early twentieth-century lubrication literature barely mentions him for example, his name is absent from E. He is credited in some biographical sketches with revolutionizing the railroad or machine industries with his devices. Historians have not agreed on the importance of McCoy's contribution to the field of lubrication. Later, Elijah McCoy became a consultant to the railroad industry on patent matters. Railroad and shipping lines began using McCoy’s new lubricators and the Michigan Central Railroad promoted him to an instructor in the use of his new inventions. McCoy continued to improve upon his design and invented several more improvements. He formed the Elijah McCoy Manufacturing Company to produce his works.Įlijah McCoy was issued his first patent - US patent #129,843 - on July 12th, 1872 for his improvement in lubricators for steam engines. Lubricators with the McCoy name were not manufactured until 1920, near the end of his career. Lacking the capital with which to manufacture his lubricators in large numbers, he usually assigned his patent rights to his employers or sold them to investors. Most of these were related to lubrication, but others also included a folding ironing board and a lawn sprinkler. He continued to invent until late in life, obtaining as many as 57 patents. This creativity gave McCoy an honored status in the black community that has persisted to this day. Washington in Story of the Negro (1909) recognized him as having produced more patents than any other black inventor up to that time. After the turn of the century, he attracted notice among his black contemporaries. His lubricator used steam pressure to pump oil wherever it was needed.McCoy continued to refine his devices and design new ones 50 of his patents dealt with lubricating systems. Elijah McCoy developed a lubricator for steam engines that did not require the train to stop. At that time, trains needed to periodically stop and be lubricated, to prevent overheating. Because of his training, he was able to identify and solve the problems of engine lubrication and overheating. The fireman on a train was responsible for fueling the steam engine and the oilier lubricated the engine's moving parts as well as the train's axles and bearings. However, the only job he found was that of a locomotive fireman and oiler for the Michigan Central Railroad. Afterwards, he returned to Michigan to pursue a position in his field. Born free in Canada, he returned as a five-year-old child with his family to the United States in 1847, where he lived for the rest of his life and became a US citizen.Īt the age of fifteen, Elijah McCoy served a mechanical engineering apprenticeship in Edinburgh, Scotland. patents, most to do with lubrication of steam engines. He was a black Canadian-American inventor and engineer, who was notable for his 57 U.S. His parents were former slaves, George and Mildred McCoy (nee Goins) had fled Kentucky for Canada on the underground railroad. This inventor was born in 1843, in Colchester, Ontario, Canada. President Gerald Ford spoke in regards to this, urging Americans to "seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history." The first celebration of the Black History Month took place at Kent State one year later, in February 1970.In 1976 as part of the United States Bicentennial, the informal expansion of Negro History Week to Black History Month was officially recognized by the U.S. The expansion of Black History Week to Black History Month was first proposed by the leaders of the Black United Students at Kent State University in February 1969. Their names, as well as their personal histories, have become synonymous with the rich legacy that is African-American culture. In celebration of Black History Month, explore our Black History collection and learn more about the black individuals who have made extraordinary achievements in their fields, including inventors such as George Washington Carver, activists like Malcolm X and Rosa Parks, athletes such as Willie Mays and Michael Jordan, and entertainers like Bessie Smith and Oprah Winfrey. Black History Month brings to the forefront, the inspiring stories of African-American icons, many of whom overcame great odds to leave their mark on the United States. There are just two limitations:ġ) It doesn't support Blu-ray menus. MPC-HC is capable of playing Blu-ray discs. 3D support was removed in newer versions. In case of NVIDIA you must use driver version 418.xx or older. Your TV should have an option to turn this into 3D. Such videos are actually encoded as 2D video. Note: playback of SBS (side-by-side) and Top/Bottom 3D video does not have the above requirements.

You can capture 2.39:1 aspect ratio footage using your regular camera. The lenses provide an incredible aspect ratio. Many films you love are shot in this format. Shoot a wide field of viewĬinematographers worldwide love anamorphic lenses, and for good reasons! They help achieve that epic cinematic look. This is known as CinemaScope, a filmmaking process in which a motion picture is projected on a screen, with the width of the image approximately two and a half times its height. Widescreen was pulled off by using lenses that capture a wider aspect ratio and squeezing the image onto a narrow film strip. Plot twist, then streaming services like Netflix and HBO came, making every living room a cinema. Shots from this lens created an exciting widescreen effect which could not be replicated in the home, forcing Americans to go to the cinema. The film industry quickly recognised the potential of anamorphic lenses, especially the ability to capture wide-angle shots to combat the rise in popularity of the televisions - which were at the time finding themselves in many American households. Failing to do this will quickly turn your magic carriage into a rotten pumpkin!

It's important to note that the images captured through your anamorphic lens need to be stretched in post-production or when projected. Essentially, these lenses maximize the use of the sensor by fitting more footage onto the sensor. Moreover, the anamorphic lens changes the dimensions of an image in one axis allowing for a wider field of view and squeeze that same image onto a narrower sensor. Their ultra-wide rectangular aspect ratios, long horizontal flares and their characteristic oval bokeh has made these lenses the ultimate go-to in the filmmaking world.

Some NPCs have zombie version textures and all mobs have nicknames. All NPCs have different textures, thus they look different and have their names and nicknames. One interesting and fun change that the ZigZag resource pack introduces is new NPCs. The inventory system is much easier to manage as it looks much better in light blue. The resource pack introduces new blocks, mobs, NPCs, flowers, trees, paintings, animations, particle effects, new music, and sound effects. While objects and mobs are still blocky, they are much more detailed and colorful. ZigZag changes many visual aspects, making Minecraft look more cartoonish but with higher fidelity. The result is the ZigZag texture pack which encompasses all their hard work, with Jamie having the most considerable contribution. Jamie and her colleagues created a private server on which they all toyed around with textures, 3D models, effects, lighting, to create a Minecraft version as they imagine it. It is the result of the hard work of Jamie Mckinernan, who has been working at Harmonix for many years. The ZigZag resource pack is one of the few resource packs that introduce a complete visual overhaul of Minecraft.

For example, if you get a sketch pad for dry media and use it for water-based painting, colors will bleed through the page. Type of Media You Useīefore choosing a sketchbook, it is important to decide on the media you want to choose because not every type of paper is suitable for each medium. However, you will definitely need something compact and lightweight to keep in your backpack if you prefer drawing landscapes and objects outside. You also need to think about where you’ll draw since if you prefer drawing from the comfort of your home, you can get a sketch pad that is bigger and bulkier. It’s a good idea to think about how you intend to use this notebook. Keep this aspect in mind before choosing a sketchbook to ensure it can handle the artwork you intend to draw. You may prefer to use only a quarter of the page or use the complete page to show your creativity. If you’re a regular artist, you’ll find that you instinctively sketch at a certain scale. How to Choose a Sketchbook Pick your preferred sketchbook size Your intended purpose will affect your decision as you need different types of papers for different activities. The most used papers in a sketchbook are cartridge-toned paper, watercolor paper, and black paper. You should look for terms like “long-lasting spine” to rest assured you are investing in the right product. A strong binding keeps all the content tightly knit to ensure that the pages won’t fall out while you move around. You need a book with a sturdy binding for a long-lasting journal. If you’re looking for something for random, quick sketches, you may want to choose a lightweight book rather than a heavy one with unnecessary pages and sheets. The more pages you want in it, the more bulky your sketchbook will be. The weight of your sketchbook is another important feature that can make or break things. Even if limiting yourself to a specific size might be difficult, it is essential to choose a notebook that is practical for your intended purpose. SizeĪ sketchbook’s size depends on your needs as an artist, writer, or just someone searching for a place to jot down their thoughts. To get the most out of their sketchbooks, artists and individuals should take the following features into account before making any purchases. There are so many sketchbook brands to choose from that it might be difficult to make a decision. It’s much easier to concentrate on your drawing when you’re using a sketchbook with a thread binding that lies flat on your desk. The lack of glue or chemicals in a thread binding makes it an excellent option for artists who are concerned about the longevity of their work. Thread bindings, which may be seen in some of the most expensive sketchbooks, make the book appear slimmer, and it is especially noticeable when compared to a wire-bound sketchbook. We recommend cutting out the pages with a precision blade to ensure a hassle-free sketching experience if you go for glue-bound sketchbooks. Glue binding is most commonly used by manufacturers that offer inexpensive sketch pads. Professional artists should avoid using glue bindings because they can get in the way of sketching and the glue type that most companies use is generally harmful from an archival perspective. Veteran artists may not choose a glue-bound sketchbook because it doesn’t lay flat on surfaces or it can be a hassle to pull out sketches. The only drawback of wired binding is that you may damage the paper when taking these sketchbooks out with you. Such sketchbooks are easy to manage, and the perforated edges make tearing the paper a breeze. The perk of spiral binding is that you can fold the pages over completely without creasing or warping the sheets. This is the most common binding type, and the easiest to deal with for artists. Binding Types for Sketchbooks: Wire or spiral bind Scroll through this handy guide to know how to choose the finest sketchbooks. For those who like to take out their sketches, the pages should be entirely perforated so they may easily be detached. If you’re looking for the greatest sketchbook, you’ll want to make sure that the paper is heavy enough, the binding is solid, and the cover is sturdy enough to preserve your work. There are so many sketchbooks to choose from, and each one excels in a different area (charcoal, marker, gel pens, toned paper, watercolors).
