  • Patent number: 5265728
    Abstract: An arrangement for retaining blister pack tablets comprises a container with at least a front cover and a rear cover with a blister pack sandwiched therebetween and visible through a window in the front cover. The blister pack includes indicia thereon indicating the order in which the tablets should be taken and the container includes a pointer identifying the first tablet in the array of tablets to be consumed. Preferably, the container includes a daily calendar in the form of a loop or cylinder which is moveable with respect to the container so that a desired starting day can be selected by the user or prescriber. Preferably, the loop or cylinder is lockable in its selected position. In accordance with two embodiments of the invention, front and rear lids are pivoted to the front and rear covers, respectively, to conceal the blister pack until it is necessary to take a tablet.

  • Patent number: 5241415
    Abstract: A circular tissue recording chamber has a cavity therein for retaining tissue or cell samples immersed in a liquid bath. The temperature of the bath is maintained at a selected level by a transparent heater positioned beneath the bath, wherein the heater is comprised of a grid of fine wires supported on a transparent mylar substrate. Liquid is introduced into the bath through a serpentine passageway also in proximity with the heater, whereby the temperature of the liquid is raised to that of the bath as it traverses the passageway. The recording chamber has a thickness of approximately 1 cm so as to be readily usable with a high magnification microscope.
