Abstract: A lightweight interchangeable magnetic sleeve and method of manufacture thereof are disclosed. The sleeve assembly comprises an annular tube in the exterior surface having recesses filled with comparatively rigid magnetic means which are firmly adhered therein. The sleeve assembly includes a tubular radially compressible liner component, relatively slightly shorter than the tube, and bonded inside and substantially axially centrally within the tube thus leaving interior cylindrical end regions of the tube exposed beyond the annular end surfaces of said liner. The remaining exposed interior cylindrical surfaces of the tube are rebated back from the liner exposing annular shoulders within the tube. The rebates are tapped so that correspondingly sized threaded end rings of a more structurally robust, rigid and resilient material than the tube material, can be fitted into the tube ends and tightened against the annular shoulders created by the rebating, placing the entire sleeve assembly under slight compression.

Abstract: An article with an operative liquid-bearing surface is adapted for transferring that liquid to a substrate material or printing plate. The entire operative surface of the article is provided with a pattern of microscopic discrete depressions which are usually laser-engraved into the surface so that a substantially continuous wall structure remains which surrounds and defines the depressions. In particular the depressions are of a cross-sectional shape which is symmetrical about one or both of a lateral and a medial axis perpendicular thereto, and arranged adjacent one another in offset fashion, and above and below one another so that the pattern thus formed is substantially uniform and repeating. Each of at least one of the pairs of lateral or medial sidewalls of any one depression are contoured, the contour of one of the pair being generally the mirror image of the other.

Abstract: A cooking apparatus for use in the microwave cooking of a food product is disclosed. The cooking apparatus includes a tray and a lid, both of which have susceptor surfaces in contact with the top and bottom surfaces of the food product, respectively. In addition, the tray elevates the food product from the bottom of a microwave, while the lid is unattached to the tray to permit the lid, and the susceptor surface thereon, to rise and/or fall according to any change in thickness of the food product during microwave cooking, thereby maintaining at least a portion of the susceptor surface of the lid in contact with the top surface of the food product.

Abstract: A package used for storing food and fluid having a food compartment and a drainage compartment, and methods of use and manufacture thereof. The food compartment and the drainage compartment are separated by one or more inner seals or divider walls having one or more passages. The divider permits fluid to flow from the food compartment to the drainage compartment, and to restrict fluid from flowing from the drainage compartment to the food compartment. This provides a package which can reduce the amount of fluid in the food compartment and facilitate removal of the food product from the food compartment, such as by upending the package, without also removing fluid from the drainage compartment with the food.
