The apparatus consists of an iron plate, 33 X 33 X 0.6 cm, fitted with three upright iron rods, each 4 4 c m long (Fig. 1). Two aluminum rods clamped across the upright rods near the top ...

Novel apparatus for the automationof solvent extraction

greater than the monochromator's specification, it should be noted that the monochromator used in this study is over ten years old. Because this error is a rather smooth and stable function of wavelength, it is possible to calculate the wavelength of an unknown emission line in a complex sample to an accuracy better than the monochromator specification. The measured wavelength is slightly depen...

Filtration Apparatus for Protein Extraction from Urine.

Selective Extraction of Isolated Mitotic Apparatus

Mitotic apparatus isolated from sea urchin eggs has been treated with meralluride sodium under conditions otherwise resembling those of its isolation. The treatment causes a selective morphological disappearance of microtubules while extracting a major protein fraction, probably consisting of two closely related proteins, which constitutes about 10% of mitotic apparatus protein. Extraction of o...

Method and Apparatus for Improved Active Sonar

The invention is a method for improved active sonar using a singular value decomposition filtering and a Volterra-Hermite Basis Expansion to model real active sonar measurements. The fitting model minimizes the sum of the squared errors between a measured channel response, z(t), and model response, y(t), which is a fitted Volterra Series solution. The model requires as input an excitation wavef...
