Binder jet 3D printing, known variously as "Powder bed and inkjet" and "drop-on-powder" printing, is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a CAD file. Binder jetting is one of the seven categories of additive manufacturing processes according to ASTM and ISO.
12" Quadruple Sector-less Wimshurst Machine (Bonetti Machine) An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained ...
In electricity generation, a generator [1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...
Microsoft Binder was an application originally included with Microsoft Office 95, 97, and 2000 that allowed users to include different types of OLE 2.0 objects (e.g., documents, spreadsheets, presentations and projects) in one file.

Nafion is a brand name for a sulfonated tetrafluoroethylene based fluoropolymer - copolymer discovered in the late 1960s by Dr. Walther Grot of DuPont. [1] Nafion is a brand of the Chemours company. It is the first of a class of synthetic polymers with ionic properties that are called ionomers.
Trapped-key interlocking is a method of ensuring safety in industrial environments by forcing the operator through a predetermined sequence using a defined selection of keys, locks and switches. It is called trapped key as it works by releasing and trapping keys in a predetermined sequence. After the control or power has been isolated, a key is ...
A modern compact binder for rice (2006) The reaper-binder, or binder, is a farm implement that improved upon the simple reaper. The binder was invented in 1872 by Charles Baxter Withington, a jeweler from Janesville, Wisconsin. [1] [2] In addition to cutting the small-grain crop, a binder also 'binds' the stems into bundles or sheaves.
