How do you power clocks with liquids?

In general, liquids have mass, take the shape of their containers, and can be made to flow at fairly constant rates. Water that is moving in a stream has what we call kinetic energy, and if we put something in the stream, the object gets pushed. If we put a paddle wheel part way into the stream, it pushes the wheel around and we can use the power converted to run machinery (such as grinding mills, pumps, or clocks). If we dump the water onto the top of the wheel, that allows the water to perform more work over a longer arc, increasing the efficiency of the energy conversion. From observations like these, many Egyptian, Chinese and Greek inventors used this power to perform some very elaborate chores, such as running water clocks (see the link below).

Why is it an arrest warrant cannot be served after 3 PM on Friday?

This isn't THAT unusual. It sounds very much like the warrant is for a minor misdemeanor or traffic offense. These type warrants customarily have this restriction on their service so that they do not interrupt someone's family life during the weekend. Felony warrants, on the other hand, seldom if ever have such restrictions on them.

Are Gridiron Pendulums used in clocks. And if so what kind of clocks?

Gridiron pendulums where first perfected by John Harrison in the eighteenth century. They were devised to compensate for the loss of accuracy due to expansion or contraction due to heat or cold in a clock. They where made of a number of steel and brass rods (with slightly different cooefficients of thermal expansion), working in different directions so that the pendulum would be mantained at a given length whatever the temperature, thus providing a better timekeeper. Historically the gridiron pendulum has been fitted to more expensive accurate clocks, usually longcase clocks. I am sure they have been fitted to just about any clock to improve accuracy, but those clocks with a longer pendulum lend themselves to the gridiron. Nowadays, with the development of Invar steel, which has virtually no expansion due to heat, there is little need for the gridiron. However because the gridiron can look appealing you can still see it in clocks made today, especially Vienna style wall clocks.
