Abstract: A device for determining rotary motions generally includes a signal generator with inwardly directed teeth or inwardly directed projections and a double-sided measuring coil which is arranged within the surface of the signal generator. The measuring coil has a core of permanent magnets and pole shoes. The pole shoes project from both sides of the coil and extend up to the inner surface of the signal generator. The pole shoes are designed, arranged and conformed to one another so that, whenever the end piece of a pole shoe points to a tooth or a projection, the second, diametrically opposite end of the pole shoe is directed to a tooth gap or depression. The measuring coil core is made up of at least two permanent magnets which are magnetized perpendicularly to the coil axis and respectively embedded between two pole shoes.

Abstract: High pressure natural gas enters the regulator at the inlet port and is directed through a filter to a passage in the valve body and into the inner chamber of the valve body. The valve means which controls the high pressure gas as it expands past a valve seat and into the low pressure chamber of the regulator body, is spring mounted in a bushing to prevent undesired vibrations. The expanded and colder low pressure natural gas is directed through a nozzle to the outlet port of the regulator body. The outlet port has a bypass orifice that leads to the diaphragm chamber. Pressure variations in the diaphragm chamber control the movement of the valve means coupled to the diaphragm means.
