For automatic level regulation of cryogenic liquids in dewar vessels reports of devices using different kinds of level sensors such as capacitance, gas-bulb, and resistance have been published. This note describes a very simple and inexpensive cryogenic liquid level controller which utilizes the for
## Abstract An all optical fiber, intensity modulated sensor for discrete liquid level sensing is presented. The highly sensitive and robust design requires only silica fibers, an optical source and a detector. The sensor probe is prepared by etching the silica fibers using hydrofluoric acid. Exper
have a component perpendicular to the surface. According to the laws of friction, this would allow a frictional force parallel to the surface which would increase the reaction further. For a sufficiently large angle between AC and the surface, and sufficiently large coefficient of friction, the bull
