Abstract: A phase-locked loop (PLL) includes a voltage controlled oscillator (VCO), a charge pump, a phase detector and a frequency detector. The phase detector detects the phase difference between an incoming signal and a VCO signal. The frequency difference between the incoming signal and a reference signal is detected by the frequency detector separately from the phase detector. During the process of attaining phase lock, the phase and frequency detectors operate simultaneously. The VCO signal is phase-locked to the incoming signal when it is present. When the incoming signal is absent, the VCO maintains a frequency close to an intended bit rate by frequency locking to a multiple of the reference signal. It, thus, avoids extreme system behavior and greatly assists rapid reliable phase lock when the incoming signal is applied following a period when it is absent. The PLL is analog for simplicity, low power, and the ability to achieve the finest possible phase resolution, while the frequency lock mode is digitally controlled for high parametric insensitivity and ease of disabling to minimize power consumption and jitter once phase lock is attained. The frequency detector includes two counters for counting the VCO and reference signals. The frequency detector inhibits either of the counters as needed to force them both to count at the same rate and uses inhibit pulses to control a separate charge pump connected directly to the integration capacitor of the PLL. The frequency detector can be easily added to a wide range of charge pump PLLs.

Abstract: A mixing and dispensing system for two reactive fluids, such as two-component polysulfide sealants, in which the dispensed fluids are supplied to a hand operated mixing and dispensing gun through a pair of flexible hoses suspended above the floor from a pivotal boom. The flexible hoses are pivotally attached with swivel joints onto the inlets of the gun that are spaced on opposite lateral sides of the gun, and the swivels are rotatable about a common generally horizontal pivot axis. The gun is fully weight supported in an operative position above the floor with a tool balancer attached to the boom. The tool balancer includes an adjustably tensioned and extendable line that is pivotally attached to the top of the gun body and rotatable about a generally vertical pivot axis. The gun passes the two reactive fluids separately through the gun body and mounted on the divided outlet of the gun is a disposable static mixer having a single inlet attached to an elongated spiral mixer tube that terminates in a dispensing outlet nozzle. A hand operated actuating trigger is mounted on the static mixer tube in close proximity to the dispensing outlet nozzle. The mixing and dispensing gun is lighter, generates less waste, and is more maneuverable than prior two component mixing and dispensing guns.

Abstract: A method for determining drilling bit condition during a drilling operation is disclosed. The method includes analyzing drilling fluid returning from a well to determine the hydrogen gas concentration of the fluid; observing fluctuations in the hydrogen gas concentration during a drilling operation; and, comparing the fluctuations to known hydrogen gas concentration fluctuations indicative of drilling conditions. The method provides an accurate, substantially real-time way of determining the condition of the drilling bit without changing the structure of the bit and without pulling the drilling bit up to the surface for visual inspection. The method also provides a way to determine if there exists non-lithological debris down hole and to measure the success of fishing operations to remove non-lithological junk. The method can be used without the modification of standard drilling techniques.

Filed: 1998-11-20
Granted: 2007-07-10
Abstract: An extremely safe non-aqueous electrolyte secondary cell free of explosions and which can promptly release the internal pressure in case of rise in the internal pressure. The non-aqueous electrolyte secondary cell has in its opening a cleavage valve obtained on bonding a metal foil to the opening. In case of rise in the internal pressure, the cleavage valve is cleft to release the pressure. In this cell, a value K corresponding to the internal volume in the cell in cm3 divided by the area of the opening in cm2 is set so that 40 <= K <= 350. By selecting the value K to a suitable value, the cleavage valve is in operation when the internal pressure reaches a predetermined value to release the pressure. The metal foil is produced by, for example, a electro-forming method or a cladding method. Preferably, a fluorine- based water-proofing agent is coated on the foil surface.
