During the classical period (roughly 1750-1820) a number of instruments fell more or less entirely out of favour, including recorders, lutes and viols. The harpsichord was replaced by the piano, and the guitar was generally heard less often than before.
78s had been phased out by the 1960s so it's very doubtful you'd have any from that decade or from the 1970s. Are you referring to LPs? If so, please post a new question so that others can help answer.
Yes, it's true that newer refrigerators do not use chlorofluorocarbons (CFCs) as refrigerants. CFCs were phased out due to their harmful effects on the ozone layer and have been replaced by more environmentally friendly alternatives, such as hydrofluorocarbons (HFCs) and other substances. As a result, modern fridges comply with regulations aimed at reducing ozone depletion and minimizing environmental impact.
No, Halon and FM-200 are not the same product. Halon refers to a class of bromine-containing compounds used in fire suppression, notably Halon 1301, which has been largely phased out due to its ozone-depleting properties. FM-200, on the other hand, is a more environmentally friendly clean agent known as HFC-227ea, which does not harm the ozone layer and is commonly used as a replacement for Halon in fire protection systems.
Yes, it is possible to use direction finder devices (usually radio receivers with directional Antennas abbreviated to "DF receivers"), the most common and oldest method is triangulation of the the two way radio signal by two and ideally three DF receiver stations, these will compare results and they will be able to locate a two way radio device quite accurately as long as it is transmitting reasonably continuously. At VHF & higher frequencies there are direction finders that use a special antenna array on top of vehicle and use methods to detect the Doppler effect by doing timing comparisons of the received two way signal by switching the receiver to different positioned and phased antennas and the results from the receiver detected pass through a signal processor which can process and and indicate the origin of a two way signal with reference to the DF receiver antenna array position and display it on a screen. Cell phones locations are detected in a similar way by using various cell sites and special processing Software to get an accurate fix on the cell phone position.
Bay Rum cologne was popular although had to be phased out during WW2.

The French Franc was phased out during the year 2001 (The Euro was phased in at the same time) and put out of commercial use on Jan 1, 2002 (but coins and notes could still be changed in banks).
Horses have not been phased out, they are still as popular as they were years ago.
Chlorofluorocarbons (CFCs) were a man-made gas that was phased out during the 1990s due to their harmful effects on the ozone layer. They were commonly used in refrigerants, aerosol propellants, and foam-blowing agents.
The Canadian one dollar bill was phased out by the Canadian National Government in the year 1987. They were phased out in July of that year. They have not been used since then.
In science and engineering, a phase refers to a distinct form of matter that is uniform in its physical and chemical properties. It can also refer to a specific stage in a process or sequence of events.
The cells that eventually form the organ systems of the infant start developing during the embryonic phase of pregnancy, which is generally considered the period from conception to about 8 weeks. This is when the basic structures of the organs begin to form through processes like cell differentiation, migration, and tissue organization.
Yes, there were slaves in Wrentham, MA during the colonial period. Like many other New England towns, Wrentham had some residents who owned enslaved individuals for labor. The practice of slavery was gradually phased out in Massachusetts, with the state passing laws to abolish slavery by the early 1780s.

The M1A1 Thompson has been phased out of service for quite some time. The last force that I'm aware of which used them with any regularity were the republics which split from the former Yugoslavia (particularly Croatia) during the Yugoslav wars. Those forces have since phased all of those weapons out of service, as well. Your likelihood of being assigned a submachinegun period is minimal, anyhow. Submachineguns are typically limited to special operations forces on an 'as needed' basis, and they've been completely phased out of line units, as they've been replaced in their roles within line units both by modern assault rifles and light machine guns.
