Hacker Craft
Hacker-Craft is the name given to boats built by The Hacker Boat Co. It is an American company, founded in Detroit, Michigan in 1908 by John Ludwig Hacker (1877–1961, known as John L. Hacker or just "John L.") and is the oldest constructor of wooden motor boats in the world. The company moved operations to New York State in the 1970s and continues to produce hand-built boats. Hacker was a naval architect and American motorboat designer. His major design and engineering accomplishments include the invention of the "V"-hull design and the floating biplane for the Wright brothers. The company was known for its runabouts, utilities, commuters, and tenders. John L. Hacker, the early years Hacker was born in Detroit, Michigan on May 24, 1877. For four years, while working at his father's business as a bookkeeper, he attended night school and took a correspondence course in order to become an accredited marine designer. Once qualified (at the age of 22) he set about solv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hacker Kitty Hawk 1911
A hacker is a person skilled in information technology who uses their technical knowledge to achieve a goal or overcome an obstacle, within a computerized system by non-standard means. Though the term ''hacker'' has become associated in popular culture with a ''security hacker''someone who utilizes their technical know-how of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them – hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques in order to collect evidence on criminals and other malicious actors. This could include using anonymity tools (such as a VPN, or the dark web) to mask their identities online, posing as criminals themselves. Likewise, covert world agencies can employ hacking techniques in the legal conduct of their work. On the other hand, hacking and cyber-attacks are used extra- and illegally by law enforcem ...

Pitting
Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the random creation of small holes in metal. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic (oxidation reaction) while an unknown but potentially vast area becomes cathodic (reduction reaction), leading to very localized galvanic corrosion. The corrosion penetrates the mass of the metal, with a limited diffusion of ions. Another term arises, pitting factor, which is defined as the ratio of the depth of the deepest pit (resulting due to corrosion) to the average penetration, which can be calculated based on the weight loss. Development and kinetics of pitting According to Frankel (1998) who performed a review on pitting corrosion, it develops in three successive steps: (or nucleation) by breakdown of the passive film protecting the metal surface from oxidation, (2) growth of metastable pits (growing up to the micron scale and then repas ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Casting
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 60% of all metal castings are produced via sand casting process. Molds made of sand are relatively cheap, and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop the strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models called patterns, by carving directly into the sand, or by 3D printing. Basic pro ...

Jig (tool)
A jig is a type of custom-made tool used to control the location and/or motion of parts or other tools. Description A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products.. An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics. Jigs or templates have been known long before the industrial age. There are many types of jigs, and each one is custom-tailored to do a specific job. Drill jig A ''drill jig'' is a type of jig that expedites repetitive hole center location on multiple interchangeable parts by acting as a template to guide the twist drill or other boring device into the precise location of each intended hole center ...

APBA Gold Cup
The APBA Gold Cup (originally known simply as the Gold Cup, a speedboat race) is an American hydroplane boat race, named for the American Power Boat Association. It is now run as part of the H1 Unlimited season. Starting in 1904, the Gold Cup consist of three heats, and starting in 1918 the heat distance was 30 statute miles. In 1963 the number of heats was increased to four, but the total distance was reduced to 60 statute miles. In 1976, the Unlimited Racing Commission adopted a winner-take-all format for all its races including the God Cup. In 1981 the total number of heats was reduced to three with the total distance being reduced to 45 statute miles. Since 1983 the Gold Cup has been competed at various total distances ranging from 36 statute miles to 52.5 statute miles. The driver with the most Gold Cup victories is Chip Hanauer, with 11 victories. Dave Villwock is second, with 10, and Bill Muncey is third, with eight.

Factory Direct
Disintermediation is the removal of intermediaries in economics from a supply chain, or "cutting out the middlemen" in connection with a transaction or a series of transactions. Instead of going through traditional distribution channels, which had some type of intermediary (such as a distributor, wholesaler, broker, or agent), companies may now deal with customers directly, for example via the Internet. Disintermediation may decrease the total cost of servicing customers and may allow the manufacturer to increase profit margins and/or reduce prices. Disintermediation initiated by consumers is often the result of high market transparency, in that buyers are aware of supply prices direct from the manufacturer. Buyers may choose to bypass the middlemen (wholesalers and retailers) to buy directly from the manufacturer, and pay less. Buyers can alternatively elect to purchase from wholesalers. Often, a business-to-consumer electronic commerce (B2C) company functions as the bridge bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chris-Craft Boats
Chris-Craft Boats was an American manufacturer of boats that was founded by Christopher Columbus Smith (1861–1939). The company was sold by the Smith family in 1960 to NAFI Corporation, which changed its name to Chris-Craft Industries in 1962. The current successor is Chris-Craft Corporation, which produces motorboats under the Chris-Craft name. History Chris Smith built his first wooden boat in 1874 at the age of 13. Years later, he built a duck hunting boat. His friends liked the way he built them, and they asked him to build them one. This was technically the start of the boat company. He soon began to build more boats and joined his brother Hank in 1881 to begin producing boats full-time. In 1910, the brothers joined with other partners to form the Smith Ryan Boat Company. The firm's name was changed in 1922 to Chris Smith & Sons Boat Company, then to Chris-Craft in 1924. The Detroit-area company became well known for its sleek racing boats in the 1910s and 1920s.
