    • Self calibrating a pyrometer includes taking two different temperatures thereby generating two voltage spectra, calculating the spectra ratio R of the two voltage spectra, determining the slope of the plot of the logarithm of the spectrum ratio versus c.sub.2 /.lambda. to arrive at a relationship between T.sub.1 and T.sub.2, solving for T.sub.1 within the spectra ratio, and arriving at a value for T.sub.2 by substituting experimentally measured values for R into the spectra ratio equation. This method is then repeated for the determination of T.sub.2. The pyrometer calibration constant h.sub..lambda. can then be determined by dividing the measured voltage spectra by the planck function at the known temperature (i.e., T.sub.1 or T.sub.2). Measurement of subsequent temperatures can now be determined by measuring the voltage spectra and dividing by the calibration constant h.sub..lambda. which will result in a planck function L.sub..lambda. (T) which can be solved to yield the surface temperature.
    • 自校准高温计包括采取两个不同的温度,从而产生两个电压谱,计算两个电压光谱的光谱比R,确定光谱比对数相对于c2 /λ的对数曲线的斜率,得到T1 和T2,在光谱比内求解T1,并将R的实验测量值代入光谱比方程,达到T2值。 然后重复该方法以确定T2。 然后可以通过将测量的电压谱除以在已知温度(即T1或T2)下的平板功能来确定高温计校准常数hλ。 随后的温度的测量现在可以通过测量电压谱和除以校准常数hλ来确定,这将导致可以解决以产生表面温度的平面函数L lambda(T)。

    • A dispenser has first and second reservoirs configured to contain first and second components of a single dose of a multi-component dental adhesive. The reservoirs are sealed by closures which are slidably received in the reservoirs. When the closures are moved from first positions to second positions, the contents of the reservoirs may be accessed with an adhesive applicator. An applicator configured to be used with the dispenser has a collar spaced from a tip of the applicator, whereby the applicator may be used to move the closures while ensuring that the tip does not contact the closures.
    • 分配器具有构造成容纳单剂量的多组分牙科粘合剂的第一和第二组分的第一和第二储存器。 储存器被可滑动地容纳在储存器中的封闭件密封。 当封闭件从第一位置移动到第二位置时,可以使用粘合剂施加器来访问储存器的内容物。 构造成与分配器一起使用的施用器具有与施用器的尖端间隔开的套环,由此施用器可以用于移动封闭件,同时确保尖端不接触封闭件。
