Abstract

The IBM 7841 Textile Color Analyzer includes a textile sample handler primarily oriented towards measuring or analyzing the colors of textile samples. Such a machine can be modified by adding a sample handler for receiving liquid samples for the purpose of measuring dye strengths. Thus, the resultant machine would include two alternate sample measuring devices and would also include means for rendering one of the devices inactive while the other is active. Shown in the drawings are two handlers, one for handling a fixed length liquid cell or cuvette and the other for handling different sized cuvettes.

Liquid Dye Strength Measuring Feature

The IBM 7841 Textile Color Analyzer includes a textile sample handler primarily oriented towards measuring or analyzing the colors of textile samples. Such a machine can be modified by adding a sample handler for receiving liquid samples for the purpose of measuring dye strengths. Thus, the resultant machine would include two alternate sample measuring devices and would also include means for rendering one of the devices inactive while the other is active. Shown in the drawings are two handlers, one for handling a fixed length liquid cell or cuvette and the other for handling different sized cuvettes.

With reference to Fig. 1, the handler thereshown includes a connector 1 adapted to be connected to the analyzer for directing light along a first fiber-optic bundle 2 from a suitable light source and then returning light through a fiber-optic bundle 3 after passing through a cell or cuvette 4. Bundle 2 is connected to a collimator 5, such as passes through cell 4 and into the aligned end of fiber-optic bundle 3. Cuvette 4 is contained in an opaque dye cell housing 6 which includes a cover 7, allowing the cuvette to be placed into and removed from housing 6. During periods when the handler is inactive, a black opaque member may be inserted in place of cuvette 4 to block the passage of light from bundle 2 to bundle 3.

As shown schematically in Fig. 3, collimator 5 includes a condenser lens 10 that receives the cone of light emergi...
