The capacitor C 1 is used to transfer energy. It is connected alternately to the input and to the output of the converter via the commutation of the transistor and the diode (see figures 2 and 3). The two inductors L 1 and L 2 are used to convert respectively the input voltage source ( V s ) and the output voltage ( V o ) into current sources.
Converting units of temperature differences (also referred to as temperature deltas) is not the same as converting absolute temperature values, and different formulae must be used. To convert a delta temperature from degrees Fahrenheit to degrees Celsius, the formula is {ΔT}°F = 9 5 {ΔT}°C. To convert a delta temperature from degrees ...
A short piece of fire hose, usually 10 to 20 feet (6.1 m) long, of large diameter, greater than 2.5 inches (64 mm) and as large as 6 inches (150 mm), used to move water from a fire hydrant to the fire engine, when the fire apparatus is parked close to the hydrant. Solid stream A fire-fighting water stream emitted from a smooth-bore nozzle.
A 9-pin to 25-pin RS-232 adapter cable. The following protocols were designed for serial communication, mostly for the RS-232 standard. They are used for uploading and downloading computer files via modem or serial cable (e.g., by null modem or direct cable connection).
The Transnet Freight Rail Class 20E of 2013 is a South African electric locomotive. In early August 2013 the first of ninety-five Class 20E dual-voltage electric locomotives for Transnet Freight Rail was lowered onto its bogies for the first time. [1] Ten of these locomotives were built by the Zhuzhou Electric Locomotive Company in China while ...
FK-15-10, which is compatible with the Scharfenberg type 10 coupler; metros and suburban railways: FK-9-6; streetcars and narrow gauge railcars: FK-5.5-4 and FK-3-2.5; As of 2020 Wabtec is working on an Digital automatic coupling (DAC) based the Schwab coupler, a possible replacement of the screw couplers in the European rail freight service.

The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and ...
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies ...
