Abstract: An apparatus for the treatment of potable water having a substantially cylindrical pressure vessel which houses an ultraviolet light. The pressure vessel is in fluid communication with a filter stage which filters the water before treatment by the ultraviolet light. An ultraviolet lamp assembly sealed within a light permeable sleeve and having a single end cap provided with electrical terminals at one end only is disposed in watertight fashion within the pressure vessel. Downstream from an inlet to the pressure vessel is a deflector/baffle assembly provided to regulate the flow pattern and flow rate of the water within the pressure vessel thereby providing a uniform flow rate to achieve optimum kill rates of bacteria and other living organisms by exposure to the ultraviolet light. The ultraviolet lamp assembly is secured within the pressure vessel by a threaded closure nut which is easily secured or removed by hand.

Abstract: A measuring scoop with molded reusable fit clip is disclosed. The measuring scoop includes a bowl with a scraping lip or shoulder used for more effectively lifting product into the bowl, an elongated handle which is integrally mounted on said bowl and a reusable fit clip on the free end of the handle, which clip is used for sealing closed a bag of product. The design of the handle as well as the design of the reusable fit clip extends the life of the molded friction fit clip by improving the clipping force as well as the clip's resistance to deformation from applied stress.

Abstract: A male/female quick-connect system is provided which is adapted to sealingly couple to the opening of a container of liquid product. The female component of the system is adapted to couple to any standard 3/4" plumbing fitment and/or 1/4" ID standpipe and is self-venting so that any stock container can be used without modification. The male component which sealingly couples to the female component is provided with a barbed tip adapted to receive a variety of feed line sizes. A one-way elastomeric valve is disposed in the male member which only allows product to flow therethrough when the male component is coupled to a source of vacuum thereby preventing product from flowing back into the container.

Abstract: A self-contained, disposable water filter cartridge for a water treatment system for treatment of potable water has one-way ball check valves at the water inlet and water outlet to the cartridge. The generally cylindrical water filter cartridge is generally spherical on one end while substantially planar on the other end and is of a welded plastic construction. Asymmetrical lugs radially disposed about the periphery of the planar end are adapted to mate with an apertured deck of a water treatment system.
Abstract: A method of evaluating follicular biopsy specimens (skin samples) in order to count the number of comedones (25) present in the specimen involving the steps of applying an adhesive, in vivo, to a subject's skin; applying a microscopic slide to the adhesive covered skin; allowing the adhesive to set adhering to the slide; removing the slide with the adhesive and the skin attached thereto, thus yielding a follicular biopsy specimen; examining the specimen under a stereoscopic microscope under cross-polarized light then evaluating the specimen using image analysis hardware and software to determine the number of sebaceous plugs or comedones existing in the specimen.
