In other words, a tool designed to drill directionally with continuous rotation from the surface, eliminating the need to "slide" a mud motor. The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [ 1 ] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for ...
A screw-propelled vehicle A screw-propelled vehicle is a land or amphibious vehicle designed to cope with difficult terrain, such as snow, ice, mud, and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving. They have been called Archimedes ...
By 1969 the company was forced into bankruptcy. Production manager Vernon Eads bought the remains of Midget Motors under the name Barthman Corporation. He moved the base of operations to Glouster, Ohio, just north of Athens where he could rent space cheaply. [1] He opened a plant in Florida, but after a fire there the company closed in 1970.
Sprint cars are open-wheel race cars, designed primarily for the purpose of running on short oval, circular dirt or paved tracks. Historically known simply as "big cars," distinguishing them from "midget cars," sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa.
A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor which is transferred as ...
The process is very similar to a dental drill used by a dentist. These tools are able to dig faster, operate in a much higher temperature environment, deliver longer downhole life, and produce a better and straighter hole quality than a conventional mud motor. In many applications turbodrills can offer their customers significant cost savings ...
A mud agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to ...
The Euclid Company of Euclid, Ohio, made specifically-designed off-road heavy haulers, compared with other companies that modified on-road trucks for off-road earth-hauling. The Euclid Crane and Hoist Co., formed in 1909 and owned by George A. Armington and his five sons, had become a large, respected and profitable operation by the early 1920s.
