In the United Kingdom the professional body is the Chartered Institute of Plumbing and Heating Engineering (educational charity status) and it is true that the trade still remains virtually ungoverned; [49] there are no systems in place to monitor or control the activities of unqualified plumbers or those home owners who choose to undertake ...
Gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. Gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. All-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber ...
A metal gate, in the context of a lateral metal–oxide–semiconductor (MOS) stack, is the gate electrode separated by an oxide from the transistor's channel – the gate material is made from a metal. In most MOS transistors since about the mid-1970s, the "M" for metal has been replaced by polysilicon, but the name remained.
A wire gate, western United States. A Hampshire gate, New Zealand gate or wire gate is a type of agricultural gate formed from a section of wire fence which can be removed temporarily. This type of gate is used where access is only needed occasionally, or when the cost of a conventional rigid gate cannot be justified.
Stoplogs are typically used in structures where the removal, installation, and replacement of the logs is expected infrequently. When larger flows of water are passing through a stoplog gate, it can be difficult to remove or place individuals logs. Larger logs often require multiple people to position and lift the logs.

A transmission gate (TG) is an analog gate similar to a relay that can conduct in both directions or block by a control signal with almost any voltage potential. [1] It is a CMOS -based switch, in which PMOS passes a strong 1 but poor 0, and NMOS passes strong 0 but poor 1.
A baby gate or stair gate is a protective barrier designed to prevent babies and toddlers from accessing areas of a home that may not be safe for them, such as stairways and kitchens. [2] Baby gates are typically constructed of metal, plastic and/or wood, and can be expanded to fit in a range of doorway widths. They may be designed for use ...
