Abstract
Abstract Means are disclosed to illuminate the contents of a vessel at the locale of mixing in such a manner that the condition of the mixture can be readily ascertained. The light source is positioned outside the transparent or translucent wall of the vessel between a pair of convolutions in the wall whereby the interface between the liquid contents and the inner wall of the vessel is illuminated by light that includes transmitted light, reflected light and refracted light transmitted from the light source to, through and in the glass or plastic wall of the vessel. Switch means are provided to connect the light source to the power source as the vessel is placed on the mixer base.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
In a blender, the combination of: a receptacle having a light transmissive vertical sidewall encompassing a blending zone; a source of light positioned adjacent to and concentrated in a diametral direction upon the outside of said wall at said blending zone; light diffusing means between said light source and said wall whereby diffused light is directed peripherally incident on the interior of said receptacle, optically interacts with material to be blended in said blending zone and is passed peripherally through said sidewall as a combined transmitted and reflected image the density of which is indicative of the blended condition of said material.
Claim 2
Dependent Claim
102 words
In a blender, the combination of: a receptacle having a light transmissive vertical sidewall encompassing a blending zone; a source of light positioned adjacent to and concentrated in a diametral direction upon the outside of said wall at said blending zone; light diffusing means between said light source and said wall whereby diffused light is directed peripherally incident on the interior of said receptacle, optically interacts with material to be blended in said blending zone and is passed peripherally through said sidewall as a combined transmitted and reflected image the density of which is indicative of the blended condition of said material.
Claim 3
Dependent Claim
16 words
A blender in accordance with claim 1 in which said light transmissive wall is transparent glass.
Claim 4
Dependent Claim
30 words
A blender in accordance with claim 1 in which said light transmissive wall is a transparent methyl methacrylate polymer characterized by its ability to reflect light along its internal surfaces.
Claim 5
Dependent Claim
47 words
A device in accordance with claim 1 wherein said encompassing sidewall is provided with facets with convoluted corners causing light rays directed through the outer surface of a facet to be transmitted along said encompassing wall through reflection and passed through the inner surface of another facet.
Claim 6
Dependent Claim
82 words
A blender in accordance with claim 1 in which said receptacle is detachably supported on a base with a drive motor therein; blending means rotatably supported within said blending zone from the bottom of said receptacle, said blending means being releasably coupled with said drive motor by relative vertical movement; pressure switching means mounted in said base and connected serially with said drive motor and said source of light and said source of light being connected in parallel with said drive motor.
Claim 7
Dependent Claim
23 words
A blender in accordance with claim 5 in which: said pressure switch means is releasably engaged by said receptacle in its working position.
Claim 8
Dependent Claim
47 words
A blender in accordance with claim 5 in which: said source of light is supported by said motor base in an open-sided housing; and said light diffusing means comprises a translucent panel carried by the open side of said housing, spaced from the side of said receptacle.
Claim 9
Dependent Claim
41 words
A blender in accordance with claim 7 in which: said wall of said receptacle is longitudinally convoluted; and said translucent panel is spaced from a pair of said convolutions with said source of light aligned with the space between said convolutions.
