Tang stamps on pocketknives as well as sheath knives were gradually changed to “Western USA” during the 1960s. Beginning in 1978 and continuing until the mid-1980s, the stamp “Western USA” was used with a letter added beneath the “USA” to indicate the production year. A-1977 B-1978 C-1979 D-1980 E-1981 F-1982 G-1983 H-1984 I-1985 J-1986
H 2 O + M + e − ⇌ OH − + MH. On the positive electrode, nickel oxyhydroxide, NiO(OH), is formed: Ni(OH) 2 + OH − ⇌ NiO(OH) + H 2 O + e −. The reactions proceed left to right during charge and the opposite during discharge. The metal M in the negative electrode of a NiMH cell is an intermetallic compound. Many different compounds ...
A 50 volt nickel–iron battery was the main D.C. power supply in the World War II German V-2 rocket, together with two 16 volt batteries which powered the four gyroscopes (turbine powered generators supplied A.C. for its magnetic amplifier driven servomechanisms). A smaller version was used in the V-1 flying bomb.
This battery contained two independent 4.5 V batteries, and had a four-pin connector. 9 V with a center tap was available by wiring in series. There were two ⌀3.2 mm negative pins spaced 9.5 mm apart and two ⌀4.0 mm positive pins spaced 14.3 mm apart. Negative and positive pins were spaced 18.1 mm apart.
The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.
On June 5, 1980, Gulf and Western unveiled an electric car, powered by a zinc chloride battery that would hold a charge for several hours and permit speeds of up to 60 miles per hour (97 km/h). By year's end, the U.S. Department of Energy (which had invested $15 million in the project) reported that the battery had 65% less power than predicted ...
The open-circuit voltage is 1.55 V, the average voltage during discharge is 1.25 V. [9] While the energy density is only around one third as that of a lithium battery, the distinctive virtue of the nickel–hydrogen battery is its long life: the cells handle more than 20,000 charge cycles [4] with 85% energy efficiency and 100% faradaic efficiency.
The company's original factory in Little Valley, New York, burned down in 1912. [2] This resulted in the factory moving to Springville, NY. [2] Beginning with World War I, Case has made military knives for U.S. servicemen including the M3 Fighting Knife and the V-42 stiletto (the latter, for the Devil's Brigade).
