摘要:
The present invention discloses a system and method for detecting the spectra of unknown components in the spectrum of a mixture and/or for verifying the presence of suspected components in the spectrum of a mixture. The system and method involves using the algorithm to perform a regression that includes the target and known spectra in a mixture, calculating a residual where the coefficient for the target spectrum is zero, called the extracted spectrum, and comparing the extracted spectrum and the target spectrum. The system and method may be used with chemometrics algorithms, multiple known spectra, and/or multiple target spectra.

Methods of calibrating a fluid analyzer for use in a wellbore are described. An example method of generating calibration data for a fluid analyzer for use in a downhole tool involves lowering a downhole tool including a fluid analyzer to a location in a wellbore, measuring, via the fluid analyzer, a characteristic value of a calibration fluid or a vacuum while the fluid analyzer is at the location, obtaining an expected characteristic value for the calibration fluid or the vacuum at the location, and comparing the measured characteristic value to the expected characteristic value to generate a calibration value for the fluid.

A method measures a property of a germicidal solution in an endoscope processor spectroscopically by placing a quantity of the solution into a cuvette and passing a light therethrough. A reservoir receives a quantity of the solution and bubbles are filtered out via a cross-flow filter prior to putting a sample therefrom into the cuvette for measuring.

Use of rocker shaft pedestals that are manufactured separately from the cylinder head and subsequently fixed to the cylinder head increases manufacturing and assembly costs of an internal combustion engine. The disclosed cylinder head obviates these problems by providing a cylinder head for an internal combustion engine that comprises a top deck and at least one integrally cast rocker shaft pedestal. A rocker shaft for use with a cylinder head of the invention includes at least one flat formed on an underside of the shaft that is adapted for mating with a top of a rocker shaft pedestal. Also described is an internal combustion engine comprising a cylinder block, a cylinder head having a top deck and at least one integrally cast rocker shaft pedestal, and a rocker shaft mounted on the at least one rocker shaft pedestal, the rocker shaft having a plurality of rocker arms mounted thereon. The rocker shaft includes at least one flat formed on an underside thereof adapted for mating with a top of the at least one rocker shaft pedestal. Also described is a method for manufacturing a cylinder head assembly including an integrally cast rocker shaft pedestal.

A method detects proper connection of fixtures to a channel in an endoscope and proper flow through the channel during a cleaning or disinfection procedure. The endoscope has a first opening into one of its channels to which is connected a fixture and a second opening which is placed into a liquid. Negative pressure at the first opening draws an amount of liquid through the channel which is measured. If the channel is blocked insufficient liquid will flow an be measured. If the fixture is not connected properly air will leak in and insufficient liquid will flow an be measured.

Underwater melt pelletizer dies which have a highly thermally conductive pathway from their heating source to the vicinity of the polymer exit end of their die holes and have a thermally insulating material at that end of their die holes have improved operability and can pelletize thermoplastics which are otherwise difficult or impossible to pelletize with such an apparatus.

Apparatus (1) for testing items of metal such as jewelry comprises a housing (3) which is closed at one end (3a) and partly open at the other end (3b). Sealed within the housing is an insert comprising a reservoir (5) containing a testing chemical and an applicator (7). The applicator extends into the reservoir (5) and projects from the housing through its partly open end (3b). The outer surface of the applicator (7) projecting from the housing forms a tip which is used to apply the testing chemical to the surface of the metal under test.
