  • Patent number: 6905650
    Abstract: A molded floor covering for a vehicle floor includes a thermoplastic polymer layer with an integral, threaded drain tube extending therefrom. The drain tube is configured such that a distal end thereof can extend through a drain hole in a vehicle floor when the floor covering is installed within a vehicle. The drain tube includes a threaded bore that is configured to receive a correspondingly-threaded drain plug therein. A method of producing a molded floor covering having an integrally formed, threaded drain tube includes providing a mold having a contour of a vehicle floor with an outwardly projecting threaded member. A layer of thermoplastic polymer is vacuum formed over the mold and around the threaded member such that the layer follows the contours of the mold and threaded member to form an elongate tube extending therefrom.

  • Patent number: 6420147
    Abstract: Haloalkaliphilic bacteria have been isolated from samples of soil, water, sediment, trona (NaHCO3.Na2CO3.2H2O) and a number of other sources obtained from in and around hypersaline soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other, as well as to other known haloalkaliphilic bacteria. In addition, these bacteria are further circumscribed by chemotaxonomic analysis. The bacteria produce various alkali- and salt-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH, saline environment.

  • Patent number: 6383546
    Abstract: The invention pertains to the formulation and process for producing a universal fruit base, which is an apple mash-polysaccharide mixture to which fruit puree(s) and optionally concentrated fruit juice(s) are to be added to form beverage concentrates. The beverage concentrates are to be diluted with water and/or fruit juice(s) to create supreme, distinctive, refreshing, healthy, creamy, smooth, thick, non-gummy and non-settling fruit beverages (smoothies). The resulting beverages possess hydrated cellular particulates, which are stabilized by modified starch and xanthan gum and thus sedimentation of particulates does not occur during the storage of the resulting beverages. Homogenization is not required for particulate stabilization. Pasteurization and sterilization of the resulting beverages can be carried out without the loss of textural and flavour quality attributes and without particulate destabilization and sedimentation.

  • Publication number: 20010037214
    Abstract: A method and system that incentivizes an employee to forego coverage under one or more health care plans maintained by the employee's employer (the “Sponsoring Employer”). According to the method and system, an employee eligible for health care coverage under another plan or plans not sponsored by the Sponsoring Employer is given the option to elect between coverage under (a) a reimbursement account or plan maintained by the Sponsoring Employer that covers eligible health care expenses not covered under such other plan or plans (including, but not necessarily limited to, deductibles, coinsurance and co-payments) and (b) the Sponsoring Employer's other health care plan or plans.

  • Patent number: 6290279
    Abstract: Floor drains are provided that can be inserted through floor coverings and through multiple floor panels of a vehicle body. An elongate hollow body terminates at an open distal end and at an open proximate end. A flange extends circumferentially around the open proximate end. One or more resilient members extend circumferentially around, and outwardly from, the body in adjacent spaced-apart relationship with the flange. The resilient members are configured to secure the floor drain within a vehicle floor panel such that the flange compressively engages the floor panel.

  • Patent number: 6291229
    Abstract: The present invention provides novel aerobic, Gram-positive alkaliphilic bacteria which have been isolated from in and around alkaline soda lakes. These alkaliphiles have been analyzed according to the principles of numerical taxonomy with respect to each other and also to a collection of known bacteria. In addition, these bacterial taxa are further circumscribed by an analysis of the lipid components which serve as chemotaxonomic markers. The alkaliphiles of the present invention produce alkalitolerant enzymes which are capable of performing their functions at high pH which makes them uniquely suited for applications requiring such extreme conditions.

  • Patent number: 6131395
    Abstract: A method for densifying the LO2 propellant of a vehicle (10) includes providing a heat exchanger (16) including a chamber (22), and an isolated heater (24) and cooler (26) located within the chamber (22). The method further includes the step of pumping propellant (LO2) (with pump 14) from the vehicle (10) to the first port (24i) of the path of the heater (24), to thereby create a flow of propellant (LO2) through the heater (24) path, and from the second port (24o) of the path of the heater (24). In conjunction with the pumping, propellant (LO2) is coupled from the second port (24o) of the heater (24) back to the vehicle (10), to thereby establish a recirculating flow of propellant (LO2). The chamber (22) of the heat exchanger (16) is filled with at least sufficient cryogenic liquid (LN2) to cover at least a portion of the path of the cooler (26), and preferably the entirety of the path of the cooler (26).

  • Patent number: 5922382
    Abstract: This invention relates to a novel method of preserving fresh cut fruit for a prolonged period of time. More particularly, this invention is directed to a novel method of preparing and preserving fresh, vitaminized flavored or unflavored cut apple pieces to be stored in containers for extended periods of time of up to 6 weeks at refrigerated temperatures with the retention of acceptable naturally-occurring and adjunctive flavors, crisp texture and original whiteness or yellowness, being free of enzymatic browning.
