摘要:
A sealed container comprising a cup and lid and a method for sealing such a container is disclosed. The cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.

A sealing head for a lidding machine is disclosed. The sealing head comprises a ball-and-socket joint that allows the head to provide an even, consistent seal when the orientation of the lid and container is not perfectly perpendicular with the sealing head. The sealing head also comprises an insulator portion that rests against the lid during sealing to protect the contents of the container from excessive heat. Heat is applied to the lid through a rim that extends around the circumference of the insulator portion.

A lidding machine and method for filling containers with a flowable food product is disclosed. Extraneous tabs extending from the container lids after the lids are cut apart are trimmed closely using knives with a blade curvature that matches the curvature of the edge of the containers. One or more "feet" are used to hold the lids in place during the cutting process. A two-layer lid may be used for such containers, the inner lid having openings through which the food product may be dispensed, and the outer lid being removable. The outer lid may be designed so that it partially covers the inner lid, and has a tab that does not extend beyond the edge of the container. The consumer may open the container by pulling this tab back across the inner lid.

The present invention provides metal powder compositions for pressed powder metallurgy and methods of forming metal parts using the metal powder compositions. In each embodiment of the invention, the outer surface of primary metal particles in the metal powder composition is chemically cleaned to remove oxides in situ, which provides ideal conditions for achieving near full density metal parts when the metal powder compositions are sintered.

An article, such as a lens article (10, 10′, 10″, 100) containing a first component, e.g., a filter (14, 14′), or component thereof, having a minimum degradation temperature, and a second component, e.g., a substrate (22, 22′), comprising a blend of first and second thermoplastic polymers. The first polymer, which has a glass transition temperature higher than the minimum degradation temperature of the first component, is selected based upon its ability to provide the article with one or more desirable characteristics. The second polymer is blended with the first polymer in a predetermined amount that provides the blend with an adjusted glass transition temperature lower than the minimum degradation temperature of the first component so that the first and second components can be heat processed together at a temperature greater than or equal to the adjusted glass transition temperature but below the minimum degradation temperature.

The method of compacting agglomerated powder comprises the steps of receiving a mass of agglomerated powder of random sizes; separating the mass into at least three distinct range of sizes including a fine range, a medium range and a coarse range; and thereafter compacting the agglomerated powder of each of the ranges into green briquettes, each of which is characterized in having a self-supporting structure to permit handling for a subsequent sintering operation to form a bonded compacted mass.

An elevator load bearing assembly (30) includes a jacket (34) having different portions comprising different polymer compositions. In a disclosed example, a plurality of tension members (32) are at least partially surrounded by a first portion (36) comprising a first polymer composition. A second portion (38) establishes at least one exterior surface (40) of the jacket (34) and comprises a second polymer composition. In one example, a surface-modifying agent is added to alter the composition of at least a portion of the jacket (34). In another example, co-extrusion techniques using different polymer compositions establish different portions of the jacket (34).

In one embodiment, a system for providing fault-tolerant inertial measurement data includes a sensor for measuring an inertial parameter and a processor. The sensor has less accuracy than a typical inertial measurement unit (IMU). The processor detects whether a difference exists between a first data stream received from a first inertial measurement unit and a second data stream received from a second inertial measurement unit. Upon detecting a difference, the processor determines whether at least one of the first or second inertial measurement units has failed by comparing each of the first and second data streams to the inertial parameter.
