Abstract: The invention relates to a process for increasing the amount of enzymes in a grain by germinating the grain in conditions in which the grain is wounded. The invention also relates to hydrolases obtainable from grains for use in food processing and manufacturing industries, to the germination of grains such as barley and to isolation of enzymes from grains.

Abstract: Novel DNAs are provided which code for fish PACAP and GHRH-like peptide. Methods are provided for production of fish PACAP and fish GHRH-like peptide by expression of the novel DNAs. Additionally, methods are provided for producing enhanced growth of fish by transfection with the novel DNAs of the invention. Further a method is provided for identification of transgenic fish.

Abstract: A multifunctional liquid sampling, metering and transfer valve assembly and the analytical system employing same. The valve assembly is capable of performing all liquid handling functions therewithin. The valve assembly comprises a pair of coaxially arranged valve discs engaged in frictional, sealed face to face disposition and includes plural axially parallel through passageways arranged for selective communication, one disc being rotatable relative to the other. Plural dedicated flow paths are defined by said passageways for metering, storing and delivering precise volume aliquots of sample, of diluent and of lysing reagent (in respect of blood cell study) from sources of said liquids to mixing and/or testing chambers. Vacuum is employed to move the liquids along the dedicated flow paths aiding in preventing leakage from the junctions of the passageways within the valve assembly along the engaged surfaces.

Abstract: Automatic printing apparatus wherein a single turnaround item-document is utilized as an initial source of intelligible information-data and thereafter by comparing certain of the data on the document with additional data inputted thereto by means of operably associated external hardware and subsequently summarizing the total data on the item effective to provide a final document including both the initially inputted information-data as well as the data resulting from the comparison and summarization.

Abstract: Pipettor apparatus for dispensing accurate and precise amounts of liquid employs a first pump having a delivery capacity sufficient to handle substantially all of the liquid to be dispersed and a second pump whose delivery capacity is adjustable and only a fraction of the capacity of the first pump.

Abstract: Pipettor apparatus for automatically and rapidly transferring accurate and precise multiple quantities of samples (e.g., blood serum) and reagent to the rotatable transfer disc of a centrifugal analyzer.

Abstract: In optical glass fibres formed of high-silica glass which is susceptible to the production of color centers on drawing into fibres, the attenuation due to such drawing-induced color centers is suppressed or reduced by incorporating from 1 to 100 (preferably 3 to 50) parts per million of cerium oxide in the glass from which the fibre is drawn, under oxidizing conditions such that a significant proportion of the cerium is in the form of ceric ions and the total attenuation is not more than 20 dB/Km in the wavelength range from 800 to 900 nm.

Abstract: A concentrating vortex shaker for the simultaneous shaking and concentration of a multiplicity of liquid samples comprises a heat-conductive block having a plurality of openings for receiving laboratory vessels containing sample liquids and removably mounted on a base provided with an adjustable eccentric drive for displacing the block in a gyrating motion. An airtight cover is removably mounted on the block and forms a chamber above the samples which can be controllably evacuated. The samples can be heated or cooled by a temperature-controlled liquid which is fed through a channel formed in the block or heated by an adjustable electrical heater provided in the block mounting or cooled by a cooling plate, upon which the block mounts.
