Abstract: A cosmetic sampler comprising an elongated base formed from a sheet with a top portion and a bottom portion. The top portion has an applicator portion and a discard portion separable from the applicator portion. The discard portion has a first hinge therethrough at a midpoint thereof and perpendicular to the longitudinal axis of the base and a second hinge therethrough where the top portion connects to the bottom portion. There is a cosmetic product disposed on a part of the applicator portion and a transparent protective layer disposed over the top portion of the base. An adhesive attaches the protective layer to the base, covering the discard layer above the first hinge and only partially covering the discard layer between the first hinge and the second hinge, so that the protective layer is easily lifted off of the base below the first hinge.

Abstract: A cosmetic sampler comprising three panels connected to each other via scored hinges. There is an application tip cut into the second or middle panel that extends upward from a first end panel when the middle and first end panels are folded against each other. A single dose of a cosmetic product is deposited on the tip. A third end panel extends from the middle panel and has a hole cut therethrough. The hole directly overlies the tip when the third end panel is folded over the other two panels so the cosmetic is visible through the hole. The sampler is maintained in a folded state where the third end panel overlies the other two panels until the sampler is used. At this point, the sampler is opened and the first end panel is folded back from the middle panel to allow the user to apply cosmetic from the tip directly to their skin.

Abstract: A combination mailer has a jacket which includes opposable leaves which are separable from a more rigid web. Each of the leaves has a cavity formed therein for containing a product sample. A vial or ampule containing another product sample is positioned between the opposable leaves and removably connected to the spine. Optionally, the jacket includes a closure device for maintaining the opposable leaves in a closed position around the vial or ampule.

Abstract: The invention provides a method and apparatus for measuring the sodium sulfide content of liquid industrial process streams. According to this method, a sample of the liquid is passed through a heated filter to remove solids and reduce viscosity and a portion of the sample is then mixed with carbon dioxide to generate hydrogen sulfide gas. The hydrogen sulfide gas is separated from the reacted liquid sample, and a portion of the gas is mixed with dilution air and then analyzed quantitively for hydrogen sulfide.

Abstract: A method and apparatus are disclosed for measuring the gaseous content of industrial process gas streams. Gas is removed from the stream at a low flow rate, under 1 liter per minute, and is passed through a heated filter to remove particulates. The gas is then cooled to about 35.degree. to 70.degree. F. in order to condense water from the stream, and is passed through a metering pump which supplies a precisely metered amount of gas which can be mixed with air for dilution. The gas is then analyzed for the desired components.

Abstract: A gas sampling extractor for extracting a stack gas sample for analysis. The gas sampling extractor includes a filter housing and an eductor in combination with gas conditioning apparatus for sampling and conditioning the emission pollutant content of a gaseous medium in a stack prior to introducing the sample gas to a measuring instrument for further analysis thereof.
