Abstract: An elongated body of molded plastics material has an end portion with longitudinally spaced and laterally extending temperature numbers overlying corresponding bands of liquid crystal compositions, and an elongated lens of transparent plastics material covers the numbers and compositions and is sealed to the end portion of the body around the compositions. In one embodiment, the compositions are carried by an aluminum strip or foil which has a center portion spaced within a cavity and opposite edge portions projecting to the outer surface of the body between the lens and the body end portion. In another embodiment, the body end portion has longitudinaly spaced cells or cavities for receiving the liquid crystal compositions in a slurry form, and in a further embodiment, the body is molded of a transparent plastics material and has an end portion which forms a second lens to provide a double-sided thermometer.

Abstract: A device for detecting thermal differentials emanating from a radiant source by transforming such differentials to visible representations that can be photographically recorded for subsequent diagnostical and analytical study. The device includes a light transmitting housing having one end supporting a resilient frame with a flexible thermally responsive screen an opposite end supporting a camera. The device is especially useful in the early detection of cancer or of other contralateral heat differentials in the body due to various abnormal or disease conditions or to monitor chemotherapy or progress of surgical recovery.

Abstract: A method is disclosed for recording topological thermal data by scribing onto a thermographic indicator overlay thermograms produced by a thermochromatic band composed of temperature responsive liquid crystalline materials and temperature gradients of the thermograms determined with a surface thermometer having a plurality of display areas composed of thermochromatic compositions each exhibiting a distinct temperature event range spaced from the others by a temperature interval. Such method is especially adapted for application to the surface of the human body for the early detection of carcinomas as evinced by elevated temperature areas.

Abstract: A combination of two or more shear-sensitive cholesteric compounds in a carrier (which can be a third cholesteric ester) creates a mixture of liquid crystals which may be colored or clear which when subjected to a rubbing action produce various colored crystal formulations due to the shearing of the crystals in the physical application of the formulation to a surface. A variety of colors from light red to dark blue can be created which disappear as the cholesteric esters are absorbed into the surface. During the application of these formulations a desirable color display is created which adds to the attractiveness of the system, particularly as cosmetic ingredients. Because the cholesteric materials are usually esters of cholesterol, they are readily taken up by the skin and are desirable components for cosmetic formulations.

Abstract: A cardboard panel is printed with identifying and advertising information and carries an article confined between two flexible sheets of transparent plastics material. The sheets are heat-welded together to form a display case for the article and have outwardly projecting border portions which are adhesively bonded to the front face of the panel. A line of weakening is formed within the sheets between the case and the border portions to provide for separating the case from the panel and to provide a reusable storage and carrying case for the article.
