  • Patent number: 6035798
    Abstract: A marine anchor for recreational boats comprising a rotating hub, with a plurality of flukes extending outward, and a substantially right-angle shaped bail member including five bail positions for receiving a slidable shackle of an anchor chain. The first bail to shakle position is the anchored position. The second bail to shackle position allows for a conventional retrieval of the anchor from above the location of the set anchor. An alternate retrieval can result in a third bail to shackle position from an anchored boat position further away from the set anchor. In the second and third positions the flukes are free to rotate enabling the marine anchor to be retrieved. A fourth position of the bail to shackle position is pulling the anchor chain and shackle from the opposite end of the anchor. A fifth position of the bail is a resting position on the bed of the sea floor by releasing the tension of the anchor chain such as during a slack tide to minimize entanglement with other loose anchors or debris.

  • Patent number: 5947921
    Abstract: Transdermal transport of molecules during sonophoresis (delivery or extraction) can be further enhanced by providing chemical enhancers which increase the solubility of the compound to be transported and/or lipid bilayer solubility, and/or additional driving forces for transport, such as mechanical or osmotic pressure, magnetic fields, electroporation or iontophoresis. In a preferred embodiment the ultrasound is low frequency ultrasound which induces cavitation of the lipid layers of the stratum corneum (SC). This method provides higher drug transdermal fluxes, allows rapid control of transdermal fluxes, and allows drug delivery or analyte extraction at lower ultrasound intensities and other forces or concentrations than that required if each means of enhancing transport is used individually.

  • Patent number: 5942263
    Abstract: A method of manufacturing cheese which is simulative of pasta filata cheeses, but which does not require a mixing and/or molding step, and the cheese product produced by the method, are disclosed. The method includes the steps of pre-acidifying milk; ripening the milk with a mesophilic starter culture to yield cheese milk; coagulating the cheese milk by adding a coagulant to yield a coagulum; cutting the coagulum to yield curds and whey; separating the curds from the whey and washing the curds in water; and proceeding directly to salt, hoop, and press the curds in the absence of any milling, mixing, or molding of the curds.

  • Patent number: 5633836
    Abstract: A time-delayed message indicator system typically displays a printed message pattern on a contrasting viewing surface at a predetermined time after activation. One preferred indicator system employs a migrating message pattern and has a laminar, multilayer construction. The message is printed on a source layer using a migratable ink. An opaque layer overlies the source layer and a release layer protects the migratable message from contact with the opaque layer until the system is activated by removal of the release layer initiating migration of the message ink through the opaque layer. Arrival of the message agent at the viewing surface initiates development of a visible message pattern. To enhance the development process the invention includes a message development trigger, for example, a heating system. The heating system can consist of exothermic chemical reactants that are mixed to react and produce heat, for example by oxidizing iron filings or activated carbon.

  • Patent number: 5554398
    Abstract: The present invention is drawn to a process for manufacturing reduced-fat cheeses. In particular, the present invention is a process for the manufacture of reduced-fat Cheddar cheese. The process is characterized in that the initial coagulum is cut at a firmer state than in conventional Cheddar cheeses, the whey is drained from the curds at a relatively high pH, and the pH is maintained at a high level at the time the curd is milled and salted. The curds are neither washed nor rinsed with water during the process.

  • Patent number: 4882179
    Abstract: A method of manufacturing a specialty cheese according to the teachings of the present invention is disclosed relating to the manufacture of a creamy Havarti style cheese. According to the present invention, to reduce the moisture content, the curd is cooked at a temperature exceeding the recommended maximum temperature for optimum acid production for a mesophile culture and specifically at a temperature in the range of 104.degree. to 106.degree. F. for a cooking time in the range of one hour for retarding the culture growth to restrict the number of cells to reduce the bitterness in the cheese and for modifying the enzymatic activity of the starter organisms while still achieving acceptable acid production. Further, according to the present invention, the change of balance between the enzymatic activities previously accomplished by chilling the curd with a water bath treatment is accomplished by curing the cheese in a first curing regimen at a temperature in the range of 55.degree. to 65.degree. F.
