  • Publication number: 20240131152
    Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

  • Publication number: 20160088855
    Abstract: The present disclosure relates to a method for the manufacture of a cream cheese, the method comprising: providing a milk- and cream-containing dairy composition; fermenting the milk- and cream-containing dairy composition to form a mixture of curds and whey; forming a concentrated mixture by removing at least an aqueous portion from the mixture of curds and whey; forming a cream cheese from the concentrated mixture; the method further comprising obtaining a retentate by ultrafiltrating and/or microfiltrating a mixture of skimmed milk and an acidic aqueous by-product of a cheese-making process, and: a) supplementing the milk- and cream-containing dairy composition with at least a portion of the retentate; and/or b) supplementing the concentrated mixture with at least a portion of the retentate.

  • Patent number: 8051996
    Abstract: A baby bottle storage assembly includes a bottle that has a cylindrical body, a chamber formed therein, and has open top and closed bottom ends. First and second coextensive protective caps are conjoined to the top and bottom ends. The second protective cap has a cavity positioned adjacent to the body's bottom end, defining a storage chamber when the second protective cap is secured to the bottom end. A first discharge nozzle is intercalated between the first protective cap and the body's top end, and has a nipple protruding outwardly from the first protective cap. Spare discharge nozzles are housed within the storage chamber and are intercalated between the second protective cap and the body's bottom end such that the spare discharge nozzles are isolated from ambient surroundings. The first and spare discharge nozzles are formed from resilient rubber material.

  • Patent number: 7560225
    Abstract: A process for ion milling using photoresist as a mask is described. In a preferred embodiment the invention is used in the fabricating air-bearing features on sliders for use in magnetic storage devices. According to the invention the photoresist (liquid or dry) is applied, developed and removed as in the prior art which includes baking steps. The embodiment of the invention includes an additional baking step beyond whatever baking steps are used in the photolithography process. The additional baking step is preferably performed immediately prior to ion milling. The additional baking step according to the invention yields increased uniformity of the depth of the ion milling which is believed to result from reduction of volatile material such as water in the photoresist. When the invention is used as part of the manufacturing process for ion milling the air-bearing features on a slider, the features are more uniform which improves the overall quality and performance.

  • Patent number: 7296420
    Abstract: Embodiments of the present invention are directed to a pallet assembly which facilitates direct cooling of the wafer carrier. In one embodiment, the pallet assembly comprises a frame which holds at least one carrier of a component. The pallet assembly further comprises a tray which is operable for being mechanically coupled with the frame. The tray comprises at least one discreet region which corresponds with the carrier when the tray is coupled with the frame. In embodiments of the present invention, the discreet region comprises at least one hole extending through the tray for permitting a coolant medium to dissipate heat from the carrier.

  • Patent number: 6132632
    Abstract: A method and apparatus for achieving etch rate uniformity in a reactive ion etcher. The reactive ion etcher generates a plasma within a vacuum chamber for etching a substrate disposed at a cathode of a reactor can within the chamber wherein the plasma emanates from a top plate of the reactor can, and is influenced by localized magnetic fields for locally controlling etch rates across the cathode to produce a uniform etch rate distribution across the cathode as a result of the localized magnetic field. The magnet array may be disposed between the top plate and the vacuum chamber for providing the localized magnetic fields. The magnet array includes a plurality of individual magnets and a grid plate for holding the individual magnets in position.
