Granted: 2003-07-16
Abstract: A coating system and method of applying coatings includes applying a first coating having an ultraviolet (UV) indicator therein to an area. The area visually inspected with a UV light and defects are remedied until the area passes the visual inspection. A second coating without a UV indicator is applied over the first coating and visually inspected, with the first coating being visible with a UV light at portions wherein the second coating does not cover the first coating. The second coating is reapplied to portions of the area not passing inspection until the second coating passes inspection. The system also includes three, four or more coating layers in some embodiments with layers having a UV alternated with layers without a UV indicator.

Title: Method for extending the useful life of a cordless telephone backup battery during a power outage condition
Inventor: BERNARD BRUCE
IPC: H04M1/73
Filed: 2001-04-25
Granted: 2004-02-11
Abstract: The disclosure discloses a method for extending the length of time over which a cordless telephone system can operate without an external source of power. The method involves detecting a power supply outage, determining that a telephone call is not currently being handled, placing the portable unit into a mode of reduced power consumption, and placing the base unit into a mode of reduced power consumption. After a period of time, the base unit resumes functionality, determines whether a call is being initiated, and handles any such calls.

Title: Process for preparing an amorphous metallic article having an extended surface area
Inventor: SCRUGGS DAVID MILTON
IPC: B01J37/00
Filed: 1985-08-30
Granted: 1988-08-17
Abstract: An extended surface area amorphous metallic article and process for preparation thereof, wherein a homogeneous amorphous metallic alloy is phase-separated to produce two interconnected, internally continuous, amorphous phases, and then one phase is removed. Preferably, the homogeneous metallic alloy has a composition associated with a eutectic between at least two solid solutions. Phase separation is accomplished by exposing the alloy to a temperature which is below the crystallization temperature and also below the phase separation temperature for that composition. Removal of one phase may be accomplished by leaching in a liquid solution, or by vaporization. The resulting article has an extended surface area of the amorphous phase that is not removed. A porous membrane having extended internal surface area may be prepared by continuing the removal process to the removal of one phase throughout the entire thickness of the article. The extended surface area articles, wherein the extended surface area is of an amorphous metal, enjoy particular advantages when used as catalysts.

Title: Optical amplifiers
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G02F1/39
Filed: 1985-11-15
Granted: 1988-06-08
Abstract: @ An optical signal pulse to be amplified and a pump signal pulse are launched consecutively into one end of an optical fibre, which may comprise a separate fibre or part of a transmission line. The pulses differ in wavelength by one or more Stokes shift and the order of launch is determined by the relevant group velocities in the fibre. Owing to dispersion in the fibre the pulses overlap and overtake one another while they are transmitted along the fibre, the signal pulse being amplified as a result of Raman stimulated emission and compressed as a result of power depletion from the pump pulse, thus increasing the bandwidth of the transmission line.

Title: Method of tempering edible compositions
Inventor: GROEN JOHN WILLIAM
IPC: A23G1/18
Filed: 1987-02-02
Granted: 1990-03-21
Abstract: A method of tempering edible fatty compositions such as chocolate involves controlling the temperature of the composition to a predetermined temperature, passing the temperature-controlled composition continuously through a heat exchanger (102) monitoring the consistency of the composition being discharged from the heat exchanger (102) and using this to control the cooling of the composition in the heat exchanger (102). Monitoring of the consistency may be affected by monitoring the pressure difference across the heat exchanger (102) using pressure transducers (114) and (116), or it may be effected by other means such as monitoring the motor used to effect mixing of the composition in the heat exchanger or by use of an in-line viscometer.
