Title: Coating bottles
Inventor: GILES BRIAN
IPC: B65G49/04
Filed: 1985-10-08
Abstract: PET bottles are coated with a barrier layer of PVDC to prevent permeation of carbon dioxide. The bottles (28) are moved through respective stages of a rotatable turret (20), each bottle (28) being clamped by its flanged neck on a structure (26) which is vertically movable. The turret mounts a reservoir (24) of PVDC for rotation with the bottles (28) so that the bottles can be moved vertically into and out from the PVDC with minimal disturbance of the PVDC surface. In this way there is avoided uneven and unacceptable coating of PVDC which might otherwise occur in such high speed production, in view of the bottles dragging across the PVDC surface. After coating, the bottles (28) remain on the turret until excess liquid drips back to the reservoir (24), the bottles then being removed to a drying oven. <IMAGE>

Title: Sealing system for hermetic microchip packages
Inventor: GRAHAM DANA R
IPC: H01L23/02
Filed: 1991-03-26
Abstract: A sealable hermetic microchip package includes a vent (46) therein that permits gas to escape during the sealing operation, but then itself is sealed at the completion of the sealing operation to render the package hermetic. The venting of gas from the interior of the package avoids the buildup of internal pressure during the sealing operation that can introduce bubbles and other faults into the sealing material. The vent may be a channel in the sealing surface of the lid of the package that is initially open, and then fills with the seal material as it flows to effect the seal. The vent may also be a hole in the lid that is sealed by the flow of a bead of the seal material. An equivalent approach to venting provides that the lid be mounted on standoffs that flow during sealing to permit the lid to settle onto the base of the package. <IMAGE>
