    摘要： An apparatus for slush molding a thin shell having an outer layer and an inner layer. The apparatus includes two tubs alternately movable to a cast position for dispensing their respective material contents into a mold cavity. According to another embodiment of the invention, the apparatus includes a diverter valve configured to alternately open a passage from each of two tubs to the mold cavity to selectively dispense charge materials from the respective tubs into the mold cavity. In addition, a method is provided for forming a thin shell having an outer layer and an inner layer. A first polymer material is cast and allowed to melt on a heated mold surface to form an outer layer. A second polymer material is then cast and allowed to melt and form an inner layer on the inner surface of the outer layer. The shell is then removed from the mold.

    摘要： A turbine blade (10) includes internal channels (16) which provide a flow passage for a cooling medium to assist in cooling the blade (10) when in use, wherein the channels (16) include a plurality of turbulence promoting ribs (28, 60, 64, 70) mounted on the wall surfaces (44, 62, 66, 72) thereof. Each rib (28, 60, 64, 70) comprises two rib portions (30, 32) joined at one end to form a chevron junction (34), wherein the chevron junction (34) defines an angle (36) of between 80° and 120° and is directed into the flow of the cooling medium through the channels (16). Each rib portion (30, 32) of a rib (28, 60, 64, 70) defines a gap (40, 42) therein.

    摘要： A method for semi-quantitatively or quantitatively detecting the presence of a microbe in a sample is provided. The method utilizes a test dye that undergoes a detectable color change in the presence of one or more microbes. For example, in one embodiment, the test dye is a solvatochromic dye (e.g., Reichardt's dye) that responds to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth. Regardless, the color of the test dye may be compared to the color of a control dye, wherein the color of the control dye corresponds to a known microbe concentration.

    摘要： The invention provides a breath testing device which includes a visual indicating agent which changes color in the presence of an odor associated with bad breath, such as sulfur and ammonia odors. An example of the visual indicating agent is 4,4′-bis(dimethylamino)-benzhydrol (Michler's hydrol or BDMB) and related dyes having a similar chemical structure. The indicating agent is applied to a substrate which is then inserted into a tube or straw, or which covers one end of a straw. When a user with bad breath blows into the tube or straw, the indicating agent will change color. The breath testing devices provide a quick and affordable means for a user to test their breath, and they may be packaged in discreet, pocket-sized dispensers which can be carried in a pocket or purse.
