Title: Internally delaminating tabbed innerseal for a container and method of applying
Inventor: MCCARTHY THERESA A
IPC: B65D17/40
Filed: 1990-01-17
Granted: 1998-08-01
Abstract: An improved innerseal for sealing containers includes a body portion having an upper surface and structure connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure adapted for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding portion which is adhered to the first bonding portion with a second bonding force which is less than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and remain adhered to the rim, while a second part of the first bonding portion will remain adhered to the second bonding portion, thereby exposing the opening in the container when the grasping structure is pulled. A method for manufacturing containers so sealed is also disclosed.

Abstract: 플랜트(102)의 파라미터를 추정하는 파라미터 동정기(103)는 모델(104), 감산기(107), 지연회로(106) 및 파라미터 적응 메카니즘(106)을 포함하고 있다. 교란은 유한 수(=m)의 임펄스로 구성되는 임펄스 트레인으로 표현되는 것으로 가정한다. 상기 모델은 플랜트의 입출력을 근거하여 플랜트의 n상태 변수 및 출력을 추정한다. 감산기는 플랜트의 출력과 추정된 출력간의 오차를 출력한다. 지연 회로는 상태 변수를 파라미터 적응 메카니즘에 인가하기 전에 N(≤n+m+1) 샘플만큼 상기 모델로부터 출력된 상태 변수들을 지연시킨다. 파라미터 적응 메카니즘은 오차와 지연된 상태 변수의 곱을 근거해서 파라미터들을 계산한다. N은 오차에 관한 교란의 영향이 교란의 초기로부터 N개의 샘플에서는 사라지도록 정해진다. 이는 파라미터 적응 메카니즘이 교란의 영향을 받지 않는 추정된 파라미터를 출력할 수 있게 해준다.
