In Europe, 12 volt plugs and sockets are not specially regulated and do not require approvals for the CE mark. [citation needed] The male plug is sometimes used to feed power into a vehicle to recharge its battery because it usually has no regulatory circuitry between the outlet and the car battery. For instance, portable solar battery ...
In most coolers gas is compressed and expanded periodically. Well-known coolers such as the Stirling engine coolers and the popular Gifford-McMahon coolers have a displacer that ensures that the cooling (due to expansion) takes place in a different region of the machine than the heating (due to compression). Due to its clever design, the PTR ...
The automatic kind will also lower when the ignition switch is turned off. Unlike most car antennas adjusted directly by hand, power antennas retract completely beneath the surface that they are mounted on. This convenience could be found on most luxury cars by the late-1950s. The automatic power antenna became much more common in the 1970s. [1]

Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
In a multi-frequency attempt, the distress signal is sent on the MF and all the HF distress frequencies in turn. As this requires retuning the antenna for each sending, without waiting for an acknowledgment, a multi-frequency attempt should only be done if there are only a few minutes until the ship's batteries are under water. As the distress ...
