A metering pump is a type of pump specifically designed to deliver precise amounts of fluid at a controlled rate. It is widely used in various industries for applications that require accurate dosing and precise flow rates, such as chemical processing, water treatment, pharmaceuticals, food and beverage production, and many more. ### Key Features of Metering Pumps: 1. **Accuracy**: Metering pumps can provide high levels of accuracy in the volume of fluid being pumped, often within ±1% or better.

The Roundabout PlayPump is an innovative device designed to provide both recreational play and access to clean drinking water in communities, particularly in rural areas of developing countries. It combines a merry-go-round with a water pump, allowing children to play on the equipment while simultaneously generating water for community use. When children spin the Roundabout, the mechanical energy generated from the motion is converted into pumping water from a borehole or well into a storage tank, making it accessible for drinking and sanitation purposes.

A sinusoidal pump, often referred to as a sinusoidal wave pump, is a type of positive displacement pump that utilizes a sinusoidal motion to move fluids. This design allows for continuous pumping action with a smooth flow rate, as opposed to the more abrupt flow patterns seen in some other types of pumps.

Trompe, or "trompe l'oeil," is a French term that translates to "deceive the eye." It refers to a visual art technique that uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions. Trompe l'oeil is often used in painting, mural art, and even architectural design to create illusions of space, depth, and texture.

A variable displacement pump is a type of hydraulic pump that can adjust its output flow rate and pressure based on the demands of the system it serves. Unlike a fixed displacement pump, which has a constant flow output regardless of the load, a variable displacement pump can change its displacement (the amount of fluid it displaces per revolution) to match the requirements of the hydraulic system.

Puppet libraries refer to collections of code, tools, or modules used within the Puppet configuration management framework. Puppet itself is an open-source automation tool used to manage and deploy applications and system configurations across various environments. Here are some key aspects of Puppet libraries: 1. **Modules**: Puppet modules are the primary building blocks of Puppet code. A module typically contains manifests (Puppet code files), templates, files, and metadata.

Chad is a type of paper that is often used for making labels, tags, or other items that require a durable and flexible material. It is typically characterized by its strength, resistance to tearing, and ability to retain printing and writing well. Chad paper is commonly found in various applications, including crafts, packaging, and office supplies.

Herman Hollerith (1860–1929) was an American engineer and inventor, best known for developing a pioneering method for processing information using punch cards. He is often regarded as a key figure in the early history of data processing and computing. Hollerith's most notable contribution came with the invention of the tabulating machine, which he created to assist in the 1890 U.S. Census.

The Glycon cult refers to a religious movement in the Roman Empire during the late 2nd century CE that centered around the worship of Glycon, a deity who was represented as a serpent. Glycon was believed to have healing powers and was associated with the Gnostic tradition, which emphasized secret knowledge and spiritual enlightenment.

Dennis Hejhal is a prominent mathematician known for his work in the fields of number theory, automatic forms, and the theory of modular forms. He is particularly recognized for his contributions to the study of the spectral decomposition of certain differential operators and for his work on the theory of automorphic forms and their applications. Hejhal's research spans a variety of topics, including the mathematical aspects of quantum physics and connections between mathematics and physics.

"Emlyn the Gremlyn" is a character from a children's book series. The character is known for its mischievous nature and playful adventures, appealing to young readers. The stories typically involve themes of friendship, creativity, and problem-solving, often incorporating relatable experiences for children.

Pelham Puppets is a British company that specializes in the design and manufacture of hand-crafted puppets, particularly marionettes. Founded in 1947 by Lawrence and Doris Pelham in England, the company became well-known for its high-quality wooden puppets that often feature intricate designs and mechanisms. Pelham Puppets are characterized by their whimsical characters, including animals, clowns, and various figures from folklore and fantasy.

"Thingee" can refer to different things depending on the context. Here are a couple of possibilities: 1. **Informal Usage**: In casual conversation, "thingee" is often used as a placeholder term for an object or item whose name the speaker cannot recall or doesn't know. It's similar to saying "thingamajig" or "whatchamacallit.

Tom Servo is a fictional character from the television show *Mystery Science Theater 3000* (MST3K). The show, which originally aired in the late 1980s and into the 1990s, features a man (initially Joel Hodgson and later Mike Nelson) trapped in a satellite in space, forced to watch bad B movies as part of an experiment by mad scientists.

Shotgun Red is a character created by comedian and ventriloquist Mike W. Smith. He is a puppet and one of the main characters featured in the "Shotgun Red Variety Show," which showcases a mix of music, comedy, and entertainment. Shotgun Red is portrayed as a humorous, country-style character with a distinctive red color and a laid-back personality.

Stick Stickly is a character and mascot that was featured on Nickelodeon during the 1990s. He is depicted as a stick with googly eyes and a mouth, serving as a playful and quirky figure. Stick Stickly was primarily known for hosting various shows and segments on Nickelodeon, particularly as a part of the network’s programming for children.

Miller Puckette is an American computer music researcher and a professor known for his work in the fields of computer programming for music and multimedia. He is best known for developing Max, a visual programming language for music and multimedia, which allows users to create interactive audio and visual applications. Puckette is also recognized for creating Pure Data (Pd), an open-source visual programming environment that is similar to Max but is freely available.

Colin Percival is a notable figure primarily known for his work in the field of computer security and cryptography. He has contributed to various areas of information security, including operating systems and secure computing practices. One of his significant contributions is the development of the "TrustedBSD" project, which aims to integrate security enhancements into the FreeBSD operating system.

W. Forrest Stinespring is known for his contributions to the field of mathematics, particularly in the area of functional analysis and operator theory. He is widely recognized for the Stinespring dilation theorem, which plays a significant role in the theory of completely positive maps and quantum mechanics. The theorem provides a way to represent these maps through the use of Hilbert spaces and is fundamental in understanding the behavior of quantum channels.

In philosophy, particularly in the context of the work of Gottfried Wilhelm Leibniz, a "monad" is an essential unit of reality that is indivisible and represents a fundamental building block of existence. Leibniz introduced monads as simple substances that are not composed of parts, and they serve as the foundation for the universe's structure and dynamics.
