A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis.
A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. The name is a registered trademark of Segway Inc. It was brought to market in 2001 as the Segway HT, and then subsequently as the Segway PT.HT is an initialism for "human transporter" and PT for "personal transporter."
A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor.
The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest hydraulic machines named after Greek mathematician Archimedes who first described it around 234 BC, although the device had been used in Ancient Egypt. It is a reversible hydraulic machine, and there are several examples of Archimedes screw installations where the screw can operate at different times as either pump or generator, depending on needs for power and watercourse flow.
A shopping cart, trolley, or buggy, also known by a variety of other names, is a wheeled cart supplied by a shop or store, especially supermarkets, for use by customers inside the premises for transport of merchandise as they move around the premises, while shopping, prior to heading to the checkout counter, cashiers or tills. Increasing the amount of goods a shopper can collect increases the quantities they are likely to purchase in a single trip, boosting store profitability.
The telautograph is an ancestor of the modern fax machine. It transmits electrical signals representing the position of a pen or tracer at the sending station to repeating mechanisms attached to a pen at the receiving station, thus reproducing at the receiving station a drawing, writing, or signature made by the sender. It was the first such device to transmit drawings to a stationary sheet of paper; previous inventions in Europe had used a constantly moving strip of paper to make such transmissions and the pen could not be lifted between words. Surprisingly, at least from a modern perspective, some early telautographs used digital/pulse-based transmission while later more successful devices reverted to analog signaling.
A urinal is a sanitary plumbing fixture similar to a toilet, but for urination only. Urinals are often provided in men's public restrooms in Western countries. They are usually used in a standing position. Urinals can be equipped with manual flushing, automatic flushing, or without flushing, as is the case for waterless urinals. They can be arranged as single sanitary fixtures, or in a trough design without privacy walls.
A corkscrew is a tool for drawing corks from wine bottles and other household bottles that may be sealed with corks. In its traditional form, a corkscrew simply consists of a pointed metallic helix attached to a handle, which the user screws into the cork and pulls to extract it. Corkscrews are necessary because corks themselves, being small and smooth, are difficult to grip and remove, particularly when inserted fully into an inflexible glass bottle. More recent styles of corkscrew incorporate various systems of levers that further increase the amount of force that can be applied outwards upon the cork, making the extraction of difficult corks easier.
A gas holder or gasholder, also known as a gasometer, is a large container in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap. Typical volumes for large gas holders are about 50,000 cubic metres (1,800,000 cu ft), with 60-metre-diameter (200 ft) structures.

Luther George Simjian was an Armenian-American inventor and entrepreneur. A prolific and professional inventor, he held over 200 patents, mostly related to optics and electronics. His most significant inventions were a pioneering flight simulator, arguably the first ATM and improvement to the teleprompter.
A water power engine includes prime movers driven by water and which may be classified under three categories:
- Water pressure motors, having a piston and cylinder with inlet and outlet valves: their action is that analogous of a steam- or gas-engine with water as the working fluid – see water engine
- Water wheels
- Turbines, deriving their energy from high velocity jet of jets, or from water supplied under pressure and passing through the vanes of a runner which is thereby caused to rotate
Charles Grafton Page was an American electrical experimenter and inventor, physician, patent examiner, patent advocate, and professor of chemistry.
An escalator is a moving staircase which carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal.

Abraham Lincoln's patent relates to an invention to buoy and lift boats over shoals and obstructions in a river. Abraham Lincoln conceived the invention when on two occasions the boat on which he traveled got hung up on obstructions. Lincoln's device was composed of large bellows attached to the sides of a boat that were expandable due to air chambers. Filed on March 10, 1849, Lincoln's patent was issued as Patent No. 6,469 later that year, on May 22. His successful patent application led to his drafting and delivering two lectures on the subject of patents while he was president.
Shankar Abaji Bhisey, Sunker Abaji Bhisey, Shanker Abaji Bhise or Sunker Bisey Abaji was a self-taught Indian inventor who was once called by the New York American as the "Edison of India". Sponsored by Indian nationalists, he moved to England where his inventions included a type-setting machine for the printing industry, an advertising innovation and so on. He then moved to the US where he designed a modification of the then popular ouija board where the supposed message of the spirit was printed onto a strip of paper. This spirit typewriter was patented in the US on 27 June 1922. He made no money from it but shortly after that he promoted a form of iodine termed as "atomidine" as a patent medicine, promoted by the American psychic Edgar Cayce, which earned him royalty and fame. He had nearly 200 inventions to his credit with 40 of them patented.
William Gray was an American inventor and entrepreneur. He is best known for inventing the coin-operated payphone and an improved chest protector for baseball catchers.
