[1] In February 1969, Emerson Electric announced plans to purchase Fisher Radio. [2] [3] To purchase Fisher, Emerson initially agreed to exchange 736,000 shares in a transaction worth approximately $75 million. [4] Emerson later agreed to pay approximately $37 million in stock to acquire Fisher. [5] The purchase was completed later that year. [6]
One example of servo valve use is in blow molding where the servo valve controls the wall thickness of extruded plastic making up the bottle or container by use of a deformable die. [9] The mechanical feedback has been replaced by an electric feedback with a position transducer. Integrated electronics close the position loop for the spool.
Camless valve trains have long been investigated by several companies, including Renault, BMW, Fiat, Valeo, General Motors, Ricardo, Lotus Engineering who developed electro-hydraulic valve actuation in the late 1980s as a spinoff of their active suspension program (both utilised similar electro-hydraulic actuation and control), Ford, Jiangsu Gongda Power Technologies, and Koenigsegg's sister ...
Ordinary valves can have many ports and fluid paths. A 2-way valve, for example, has 2 ports; if the valve is open, then the two ports are connected and fluid may flow between the ports; if the valve is closed, then ports are isolated. If the valve is open when the solenoid is not energized, then the valve is termed normally open (N.O.).
The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3 ⁄ 4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread. The half-angle (between the taper surface and the axis of the pipe) is arctan(1 ⁄ 32) ≈ 1.7899° ≈ 1° 47′.
The Fisher Horizon is a family of Canadian two-seats-in-tandem, conventional landing gear, single-engined, high-wing monoplane kit aircraft designed for construction by amateur builders. The Horizon 1 was inspired by the Aeronca Champion and its later version, the Bellanca Citabria , while the Horizon 2 was inspired by the Cessna O-1 Bird Dog .
1920 advertisement for the Thor electric washing machine. The Thor washing machine was the first electric clothes washer sold commercially in the United States. Produced by the Chicago-based Hurley Electric Laundry Equipment Company, the 1907 Thor is believed to be the first electrically powered washer ever manufactured, crediting Hurley as the inventor of the first automatic washing machine.
[1] The original intention of the Fish carburetor was to avoid the problems of the float chamber , and its sensitivity to sideways forces from acceleration and cornering. In the conventional carburetor, a venturi in the airflow creates a lowered pressure and this is enough to encourage the flow of fuel through the metering jets.
