  • Solid nutrient media useful for isolating and identifying alkaliphilic bacteria
    Patent number: 8097447
    Abstract: The present invention relates to a solid nutrient media composition having alkaline pH, useful for isolating and identifying alkaliphilic microorganisms in pure form. The media composition consists of 5-15 g of carbon source, 2.5-10 g of peptone, 2.5-10 g of yeast extract, 0.5-1.5 g of dipotassium hydrogen phosphate; 0.1-0.5 g of magnesium sulphate heptahydrate, 30 ?l-4 ml of super saturated solution of sodium hydroxide, 5-20 g of potassium chloride and 10-30 g of ?-carrageenan in one liter of distilled water. The potassium salt in combination with ?-carrageenan in specific proportion has been found to be a suitable replacement of agar in solidifying bacteriological media especially, for isolation of extreme alkaliphiles. The present invention also provides a method of using the solid nutrient media composition having alkaline pH to study biodiversity of cultivable alkaliphilic bacteria.

  • Continuous personalized plastic card manufacturing system
    Patent number: 8096719
    Abstract: A method for producing personalized cards on a substantially continuous basis. The method includes providing multiple supply rolls of card stock having a thickness of at least about 12 mils. The card stock is corona treated in an in-line corona treating unit to provide a printable surface having a surface tension energy of at least about 38 dynes/cm. Fixed and variable data are printed on individual card units of the card stock in first and second printing units of the in-line printing system. A removable activation label may be applied by an in-line label application unit to the variable data. The card units are die cut in an in-line die-cutting unit to a predetermined size. The first and second printing units are shaft driven printing units and the card units are capable of producing card units at a rate of at least 50,000 card units per hour.

  • Integrated reactor and centrifugal separator and uses thereof
    Patent number: 8097219
    Abstract: An apparatus for providing reaction of fluids and separation of products with increased residence time. The apparatus includes a stationary shell, a rotating hollow cylindrical component disposed in the stationary shell, a residence-time increasing device external to the stationary shell, a standpipe for introducing fluid into an interior cavity of the hollow cylindrical component from the residence-time increasing device, a first outlet in fluid flow communication with the interior cavity of the hollow cylindrical component for a less dense phase fluid, and a second outlet in fluid flow communication with the interior cavity of the hollow cylindrical component for a more dense phase fluid.

  • Shielding, particulate reducing high vacuum components
    Patent number: 8092927
    Abstract: A method of forming a gate valve for use in a high vacuum environment of an electron gun by machining a core of non-magnetic nickel-chromium-molybdenum-iron-tungsten-silicon-carbon alloy that is weldable with nickel alloys and has a tensile strength of about 750 megapascals, machining a cladding of nickel-iron, welding the core to the cladding to form the gate valve, and machining the gate valve so as to remove any dimensional differences at an interface between the core and the cladding. In this manner, because the final mechanical tolerance is controlled by machining instead of part assembling, extremely high alignment accuracy is obtained. The final part provides field shielding as provided by the nickel alloy shell, low stray field provided by the non-magnetic alloy, good vacuum performance, and tight mechanical tolerance control.

  • Optical parametric model optimization
    Patent number: 8090558
    Abstract: A method is presented for selecting the order in which parameters are evaluated for inclusion in a model of a film stack, which is by ranking them according to measurement precision. Further, a method is presented for determining which parameters are to be floated, set, or discarded from the model, which is by determining whether average chi-square and chi-square uniformity decreases or increases when the parameter is added to the model. In this manner, a model for the film stack can be quickly assembles with a high degree of accuracy.
