Abstract: A method of earth drilling with a sealed bearing assembly and a sealed bearing assembly. A first step involves providing a bearing assembly that has a bearing chamber sealed with fixed sealing assemblies of axially aligned seals, including a primary seal and back up seals. The sealing assemblies are capable of withstanding an intended pressure differential. A second step involves drilling with the earth drilling assembly in a downhole environment in which pressure within the bearing chamber is at hydrostatic pressure with the relative pressure differential caused by pumping activity being borne by the fixed sealing assemblies. The bearings and back up seals positioned within the sealed bearing chamber operate under relatively low pressure thereby prolonging bearing and seal life.

Patent CA-2292714-C (CA)

Filed: 1999-12-20
Granted: 2008-10-14
Abstract: Two transistors are arranged as a Darlington amplifier to produce a constant current through an output resistor coupled to the emitter of the second transistor. AC power is supplied to a full wave bridge which converts the AC power from the source to a DC signal. A first zener diode and the base to emitter voltage drops of the transistors control the voltage across the output resistor. As the input voltage to the bridge is increased above the voltage between the emitter of the second transistor and ground, the extra voltage will be dropped across the collector to emitter of the second transistor. The same current will flow through the output resistor regardless of any input voltage in a defined range. By adding a resistor and diode and detecting the voltage between the resistor and diode with respect to the circuit the zero crossings can be detected.
