Abstract: A smokeless tobacco product is provided. A tobacco product configured for insertion into the mouth of a user of that product comprises a tobacco formulation including a granular tobacco composition enclosed within a water-permeable pouch that has been treated with a substance selected from the group consisting of: an analgesic, a buffer, a coloring, an effervescent, or an organic acid.

Abstract: Growth of keratinocytes is provided by subjecting a basal medium, insulin, pituitary compound and keratinocytes to cell growth conditions. Cell growth can be provided in the absence of exogenous epidermal growth factor. A conditioned medium results after the keratinocytes are subjected to cell growth conditions, treated keratinocytes are provided, and the treated keratinocytes are subjected to cell growth conditions in a basal medium. The conditioned medium contains autocrine factor. The conditioned medium then is contacted with further keratinocytes to provide a cell growth mixture. The cell growth mixture is subjected to incubation in order to provide replicative DNA synthesis and hence cell proliferation. Cells so provided can be used for dermatological research, toxicological testing and skin grafts.

Abstract: A cathode current control system employing a current thief for use in electroplating a wafer is set forth. The current thief comprises a plurality of conductive segments disposed to substantially surround a peripheral region of the wafer. A first plurality of resistance devices are used, each associated with a respective one of the plurality of conductive segments. The resistance devices are used to regulate current through the respective conductive finger during electroplating of the wafer. Various constructions are used for the current thief and further conductive elements, such as fingers, may also be employed in the system. As with the conductive segments, current through the fingers may also be individually controlled. In accordance with one embodiment of the overall system, selection of the resistance of each respective resistance devices is automatically controlled in accordance with predetermined programming.

Abstract: An improved electronic monitoring arrangement for a rotameter utilizes a single point source of radiation at one side of the rotameter and a vertical array of detectors diametrically opposite to it. The elevation of the radiation source is identical to the uppermost elevation of the radiation detectors. Radiation from the source will thereby intersect a common remote edge of the top surface of the float within the rotameter throughout its intended range of movement along the elevation covered by the array.
