Abstract: Method and apparatus for the improved operation of an electronic computing scale provides significantly increased resolution in a first weight sub-range (0-12 pounds in the illustrative embodiment). A coarser resolution is provided in a second weight sub-range (11-100 pounds). The raw load cell voltage is communicated along first and second branches, and subjected to a different transformation in each branch to produce first and second transformed voltages. In the first branch, raw voltages corresponding to weights in the low sub-range are mapped onto a desired sub-range of voltages. In the second branch, raw voltages corresponding to weights in the high sub-range are mapped onto a second sub-range of voltages. Depending on the weight on the scale, one or the other of the transformed voltages is applied to the ADC input terminal, and the digital output is scaled accordingly. The circuitry includes a range flag and logic circuitry for sensing the digital ADC output, and controlling the range flag.

Abstract: The use of aziridinyl quinones as antitumor agents is disclosed. A compound which has been found to be particularly effective is the compound 2,5-diaziridinyl-3,6-bis (carboethoxyamino)-1,4-benzoquinone.

Abstract: The process of the present invention for preparing granules of alumina includes pretreating an alumina powder by admixing with cold water in a mixer at a temperature below room temperature, e.g., such as below about 20.degree. C., to form a pretreated alumina having a pore volume saturated with water and further having a surface area of gel structure, and agglomerating the pretreated alumina in a fluidized bed to form granules sized in the range of about 1-3 mm. The process is particularly suited to producing activated alumina in macroporous granules. The process in one aspect further includes a cold hopper for cooling alumina powder prior to the pretreating step.

Abstract: An in vitro assay procedure for the detection of non-genotoxic substances is provided which utilizes a prepared cell culture whose cytoskeleton constituents are structurally identifiable as microtubules, intermediate filaments and microfilaments. The procedure combines the test sample with the cultured cells and detects a presence of epigenetic substances by identifying structural changes in the cytoskeletal constituents in comparison to normal control cells. The assay method is rapid, accurate, reproducible, and has been demonstrated to identify toxic substances which have not been previously detected by presently known bacterial and/or mammalian cell mutagenic assay systems.

Abstract: A curable polymeric composition exhibiting good low temperature flexibility comprising about 50-90 parts by weight chlorinated polyethylene or chlorosulfonated polyethylene containing about 30-45 weight percent chlorine, and about 10-50 parts by weight of an ethylene terpolymer of 48-74 weight percent ethylene, 20-40 weight percent alkyl acrylate wherein the alkyl group contains 4-9 carbon atoms, and 6-12 weight percent carbon monoxide or sulfur dioxide. Such polymeric blends are especially useful for low temperature applications in contact with oil, e.g. automotive seals and hoses.

Abstract: Preloaded connection for supporting an annular body from an annular suspension joint. The connection includes an actuating ring, a split locking ring and a retaining nut which are positioned between the annular body and suspension joint. The connection is preloaded by applying an axial force to the actuating ring causing the locking ring to be expanded outwardly with the annular body becoming preloaded in compression and the suspension joint preloaded in tension with the preload force passing through the mating surfaces.

Abstract: An improved process is provided for the selective production of secondary amines and primary amines by bringing together under reaction conditions a tertiary amine or a secondary amine with oxygen or an oxygen-containing gas in the presence of an activated carbon catalyst, the improvement which comprises using an activated carbon catalyst wherein oxides have been removed from the surface of the carbon.

Abstract: This invention relates to a disposable container and in particular to one having an inner cup provided with a vertical front wall, a vertical rear wall, two vertical side walls and a bottom, and an outer cup provided with a bottom plate and four flaps extending from respective sides thereof.
