Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
Time-Temperature-Transformation diagram for two steels: one with 0.4% wt. C (red line) and one with 0.4% wt. C and 2% weight Mn (green line). P = pearlite, B = bainite and M = martensite. Isothermal transformation diagrams (also known as time-temperature-transformation ( TTT ) diagrams ) are plots of temperature versus time (usually on a ...
These diagrams are used to represent which types of phase changes will occur in a material as it is cooled at different rates. These diagrams are often more useful than time-temperature-transformation diagrams because it is more convenient to cool materials at a certain rate (temperature-variable cooling), than to cool quickly and hold at a ...
A hot box is the term used when an axle bearing overheats on a piece of railway rolling stock. [1] The term is derived from the journal-bearing trucks used before the mid-20th century.
The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO 2) and hydrogen (H 2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat. CO 2 is usually reduced by H 2 to carbon in presence of a catalyst (e.g. iron (Fe)) and requires a temperature level of 530–730 °C (986–1,346 °F).
In conventional DLTS the capacitance transients are investigated by using a lock-in amplifier [3] or double box-car averaging technique when the sample temperature is slowly varied (usually in a range from liquid nitrogen temperature to room temperature 300 K or above). The equipment reference frequency is the voltage pulse repetition rate.
In 1937 W.B. Schulte, [2] McGall's employer, started the company MICRO SWITCH. The company and the Micro Switch trademark have been owned by Honeywell Sensing and Control since 1950. [3] The name has become a generic trademark for any snap-action switch. Companies other than Honeywell now manufacture miniature snap-action switches.
The transmission control unit (TCU) in older automobiles with a clutchless manual transmission (without a clutch pedal) typically consists of an electrical switch connected to the gearshift, that is activated whenever the internal transmission control unit senses driver touching the gearshift to switch gears, which then primes a sensor or ...
