Abstract: This patent application describes the use of molecular imprinting as a means for preparation of anti-idiotypic imprint matrices. With this technique, imprints of artificial or natural molecules including their recognition sites, such as of molecularly imprinted polymers or biological receptors, antibodies or enzymes, can be prepared.

Alternatively, imprints or images of the artificial or biological species can be obtained directly. The so formed preparations can be used in a vast variety of applications, e.g. as new drugs, inhibitors or new affinity materials.

Abstract: An apparatus and method for custom blending and fabricating lipstick to the specific demands of individual customers. The present invention provides a kit which enables a user to blend various pigments to arrive at a very specific shade, and then blend the desired shade with a specific base to result in a desired consistency of lipstick, and which also allows the blended bases and pigments to be heated to a liquefied form and poured into a mold for hardening. Upon cooling and hardening, a conventional lipstick case can be attached to the lipstick for removal from the mold and use by the customer. The present invention therefore not only allows a user to quickly attain the specific shade and consistency of lipstick desired, but also eliminates the time consuming and unsatisfactory process of visiting multiple stores having expansive inventories of variously shaded and textured lipsticks.

Blends of biodegradable polymers such as PHB (polyhydroxy butyrate) or PLA (polylactide) were found suitable for systems. They are available commercially.

Abstract: A candle is made by first positioning a core element centrally in an upwardly open candle mold with the element spaced from an inner wall surface of the mold and from a lower wall of the mold, then extending a thin rod up through the lower wall of the mold to a position at least at a lower end of the core element in the mold, and then filling the mold around the core element and rod with molten wax. This wax is then cooled and hardened around the core element and rod to a hard body and the core is withdrawn upward out of the hard body to leave a central cavity in the body. The hard body is pushed up out of the mold and off the thin rod to leave in a lower end of the body where the rod was a passage extending to the central cavity. Finally a wick is fitted to the cavity and passage and the cavity is filled around the wick with wax. This last step can be carried out by fitting to the cavity a small-diameter hard body of wax itself molded around the wick.
