Abstract: The invention permits the application of an identifying mark onto a freeze-dried tablet without the need for application of pressure or for printing directly on the tablet. The invention comprises the preparation of a freeze-dried unit that is embossed with an identifying mark such as a manufacturer's logo, medicinal component strength, or other information relating to the unit. The desired identifying mark is first embossed onto the base of a container such as a blister pocket. Liquid suspension is then filled into the container and freeze-dried therein. The resulting freeze-dried unit in the container is thereby embossed with substantial copy of the identifying mark that was embossed on the base of the container. The embossed identifying mark on the base of the container remains thereon as well, providing at reduced manufacturing cost the added ability to learn the identifying mark on the enclosed freeze-dried unit without opening the blister pack.

Abstract: An improved method for manufacturing freeze dried pharmaceutical tablets in blister packs is disclosed. Liquid dosages are introduced into a multilayer laminated blister sheet having an impermeable intermediate layer that is positioned between first and second outer layers, each of which has substantially the same coefficient of thermal expansion. The properties of the outer layers of the blister sheet are such that there are no inter-layer stresses that will cause curvature of the blister sheet when it is subjected to temperature changes during the freezing and freeze drying steps. Following the introduction of the dosages into the depressions of the blister sheet, the dosages are frozen and freeze dried. A lidding sheet is then attached to the blister sheet to seal the solid dosages into the blister pack.

Abstract: A floatable fishing device comprising a float and fishing lamps to indicate catches of fish on hooks associated with the device. A pair of pendulum operated switches actuate two lamps, of different colors, depending on the direction of the swinging of the pendulum when the float is inclined by the pull of caught fish. The float is provided with a guide rod. A ring secured to the free end of a fishing line is slidable on the guide rod. A plurality of hooks are attached to the fishing line in spaced relationship. The device permits the fisherman to fish at a remote distance.
