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 unique system for distributing and sampling cosmetics is disclosed. The cosmetics which are normally dry, are combined with a liquid carrier and film forming agent and deposited onto a substrate. The film forming agent acts to microencapsulate the cosmetic and lightly bond the cosmetic to the substrate. When the film forming agent dries, it protects the cosmetic. Thus, the cosmetic can be applied to a substrate and covered with a paperboard sheet. Access to the cosmetic can be provided by a tear strip. Greasy cosmetics, such as lipstick, can also be applied to a substrate according to the present invention. These cosmetics are first microencapsulated with gelatin and the formed microparticles are secondarily encapsulated with a film forming agent and deposited onto a substrate. This method permits cosmetics to be distributed through the mail and as magazine inserts and the like.

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: Solidification of liquid crystalline compositions is retarded by incorporating therein compounds which are steroid derivatives of isostearyl carbonate. These novel carbonates which are quite stable to environmental factors such as ultraviolet light exposure, temperature changes, oxidation, etc., retard solidification of liquid crystalline compositions for extended periods of time. Moreover, these compounds, some of which of themselves exhibit color play, can be used in increasing amounts to increasingly narrow the color play range without noticeably decreasing the specular intensity of the color changes of liquid crystalline compositions.

Abstract: Disclosed is an improved microform card which includes a wear-strip spacer element structure located on the card surface in one of several configurations, some containing coded secondary information. The wear-strip spacer elements separate the card surface from adjacent optical elements in a card utilizing apparatus by a distance sufficient to prevent the formation of colored Newton rings at the card-to-optical-element interface. Card utilization equipment capable of recognizing the presence of wear-strip spacer elements on a microform card and using any secondary information encoded thereon is also disclosed.
