    Abstract: The invention provides a sightglass assembly for viewing the interior of a vessel, such as a reaction vessel for chemical or biochemical reactions, and is adapted to be welded to a vessel wall. The sightglass assembly comprises a window disc fused to a metal frame having a flange extending radially therefrom. The assembly is set into an appropriately sized opening in the vessel wall and the outer perimeter of the flange is welded to the vessel wall. An annular groove in the flange, surrounding the frame and window disc, absorbs stresses created by the heat of welding and thus protects the integrity of the entire unit. When installed, the sightglass assembly and inner face of the tank wall provide an easily cleanable smooth continuous surface, free of recesses and crevasses where bacteria can collect and grow or product from previous batches can accumulate and cause contamination.

  • Patent number: 5406994
    Abstract: A pour spout for conducting a liquid, such as fuel, from a portable ventless container to a tank which includes a mechanism for enabling a user to readily determine when the tank is full and when fluid flow from the portable container into the tank has stopped. The mechanism includes a window in a wall of the container and a deflector connected to the pour spout which extends into the interior of the container for directing air bubbles entering the container through the pour spout toward the window. The window permits a user to visually determine when the displaced air bubbles stop flowing which is an indication that the tank is full and flow of the liquid has stopped. The window may be in the form of a translucent thin wall section, a transparent pane mounted in the wall, or the container itself may be translucent throughout so that the displaced air bubbles may be seen when directed to a location adjacent a wall.

  • Patent number: 5275277
    Abstract: A drinking glass includes a side wall having a transparent circuitous path directed therealong extending from entrance of the drinking glass to a second position in adjacency to a floor portion of the drinking glass to indicate fluid level within the drinking glass structure. Various nomenclature and educational indicia spaces are provided along the circuitous path. A modification includes the drinking glass having a spacing to permit various webs positionable within the drinking glass side wall structure to vary the information and educational indicia available to an individual.

  • Patent number: 5099987
    Abstract: A device for storing and examining contact lenses comprises a (1) with at least two cavities (2) in each of which one contact lens can be stored. The cavity (2) can be sealed by an air-tight, water-tight lid (3) and has a base specially shaped (21) to allow storage of the contact lenses. A liquid container (4,6) which communicates with the cavities through channels (5, 7) is arranged in the body. To examine the contact lenses stored in the cavities, the body (1) is held with the mat surface of the lid (3) pointing toward a light and the observer facing the lower surface of the body (1). At least one convex lens (10) which magnifies the image of the contact lens can be mounted on the lower surface (9). The contact lens can also be examined directly in the storage container (contact lens case) under focal illumination.

  • Patent number: 4986636
    Abstract: The invention is directed to a viewing glass having a transparent pane and a pair of flanges. In order to facilitate simple manufacture of the viewing glass, it is proposed that the pane be arranged in an inside step of the one of the flanges and be surrounded by an O-ring for producing a vacuum-tight connection. The edge of the pane and the step of the flange preferably have corresponding frustoconical surfaces.

  • Patent number: 4960224
    Abstract: A tissue staining cassette includes a container for reagent, a slide retainer for securing a plurality of slides and for suspending the slides in reagent in the container with tissue specimens immersed in the reagent. The slide retainer consists of an open ended cylindrical body having channel containing inserts disposed in the body with the channels opposed for receiving the edges of slides. Depending spring arms corresponding to each of the channels are affixed in the cylindrical body and the end of each spring arm extends into its respective channel. As slides are inserted into the channels the spring arm is displaced and responsive to the displacement the slide is clamped between the end of the spring arm and a wall of the channel. In another embodiment resilient wall members extend across the bore of the slide retainer body to divide the bore of the retainer body into slide receiving areas corresponding to the opposed channels.
