A kitchen hood, exhaust hood, hood fan, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. [ 1 ]
In electrical engineering, coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill the particular purpose.
The Toyota NZ engine family is a straight-4 piston engine series. The NZ series uses aluminium open deck engine blocks and DOHC cylinder heads. It also uses sequential multi-point fuel injection, and has 4 valves per cylinder with VVT-i.
A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage V out (t) that is proportional to I(t).
He would also be a founding board member of the Radio Corporation of New Zealand. [42] Pacific Radio designs were initially quite plain, but by 1935 were perhaps some of the most art deco designs available—certainly in New Zealand. One model in particular, the Elite, is today a highly-sought-after collectible the world over. [43] [44] [45]
The Order, also known as the Silent Brotherhood, [1] was a neo-Nazi terrorist organization active in the United States between September 1983 and December 1984. [2] [3] [4] The group raised funds via armed robbery. Ten members were tried and convicted for racketeering, and two for their role in the 1984 murder of radio talk show host Alan Berg. [5]
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
A similar problem arose in the early 1980s, some 10 years before New Zealand and for similar reasons [34] in the Canadian province of British Columbia. It is commonly known in Canada as the Leaky condo crisis and has been an ongoing issue that is estimated to have caused $4 billion in damage since the 1980s. [34] [35]
