Apparatus and methods for hermetically sealing materials that cannot be satisfactorily sealed directly to one another using conventional techniques are disclosed. A laminar sheet material having adjacent bonded dissimilar metallic layers is interposed between elements being sealed. One of the metallic layers bonds metallurgically to one of the elements, while the other metallic layer is hermetically sealed to the other element using conventional techniques such as welding. The methods and appara...

A web of variable shaped packages is pinch fed in a delivery path by an underlieing endless belt and an overlying endless belt, the latter having flexible tubes thereon which conform to the shapes of the packages. The web is thus fed to a cutting station where individual packages are severed.

A method and system for verifying the presence of a lens in a transparent package. The method comprises the steps of moving the package into an inspection position, and conducting a light beam through the package and onto an image plane to form an image of the package on the image plane. The method further comprises the steps of generating a set of signals representing the image on the image plane, and analyzing those signals to determine whether a lens is present in the package. This analyzing ...

Apparatus for making flexible packages having an openable and resealable interlocking closure from a continuous web of flexible film, the closure being formed transversely to the direction of film flow at the consumer preferred position across one end of the package during package formation at line speed. The system utilizes a converter device mounted atop or adjacent to standard packaging apparatus to form a small amount of the running packaging film into the resealable closure structure as an ...

Method and apparatus for semi-automatically packing packages being supplied by automatic packaging apparatus at a rapid rate, characterized by the steps of or means for diverting the packages sequentially into one or more chutes; accumulating the packages from all chutes on a gate; transferring the packages from the gate and in a desired position into a receiver; providing clearance in the receiver for a next package or packages transferred from the gate; repeating the above steps until a predet...

The specification describes an optical fiber grating package with means for controllably adjusting the strain in the optical fiber grating count. The package is provided with two threaded members with different thread counts so that when both members are simultaneously turned axial displacement results, and the magnitude of the displacement is determined by the difference between the axial displacement of the two threads.

Asphalt is packaged in consumable containers (10) having breakage means, such as short notches or long channels (110, 111), to allow for easy breakage into smaller portions for ease of handling and feeding into kettles. The containers are advantageously made of an asphalt-polymer composition so that the entire asphalt package may be melted in a kettle, e.g., for use in a roofing or paving application. The containers may have various features to enhance processability and handleability, including...

A trimmer for a lumber package. The trimmer comprises a reciprocating, retaining carriage to receive the lumber package. A first track. Means reciprocate the retaining carriage along the first track from a loading position through a second position. Cutting means on each side of the track at the second position trim the lumber package. Compressor means are reciprocable at the loading position to compress a lumber package in a direction substantially perpendicular to the first track. Releasable r...

A packaging film which shrinks to form at least part of a package when exposed to heat. The packaging film includes a thin film substrate that contracts or shrinks when heated and which is substantially transparent to radiant energy. The film also includes a susceptor material carried by the film that is sufficiently opaque to radiant energy to absorb and transfer to the substrate enough heat energy to cause the substrate to shrink, when the film is exposed to a source of radiant energy. In one ...

A semiconductor package comprising multiple stacked substrates having flip chips attached to the substrates with chip on board assembly techniques to achieve dense packaging. The substrates are preferably stacked atop one another by electric connections which are column-like structures. The electric connections achieve electric communication between the stacked substrates, must be of sufficient height to give clearance for the components mounted on the substrates, and should preferably be suffic...
