Patent CA-2125147-A1 (CA)
Title: Elasticized Sanitary Napkin
Inventor: SNELLER DIANE L
IPC: A61F13/00
Filed: 1992-12-09
Abstract: A unitary disposable absorbent article (20) such as a catamenial pad or incontinent pad is provided with an elasticized side flap (30) by operatively associating an elastic member (32) on both the upper surface and the lower surface of the side flap (30). The elastic member is preferably joined to the inner surface (48) of the side flap as well as the outer surface (46) of the side flap by folding it about the distal edge (50) of the side flap. In a preferred embodiment, the elastic member (32) comprises an elastomeric laminate of an elastomeric layer (42) and a coverstock layer (44), with the coverstock layer (44) being on the outside (46) of the product, so that the sanitary napkin is provided with soft longitudinal edges (38) which contact the wearer during use. In addition, the elastomeric laminate provides relatively low tension that while raising the side flaps (30) of the product to be a barrier against lateral leakage, also maintains the product in a shape which does not encourage fluid run-off or leakage at the ends of the pad as well as providing a bunching benefit.

Patent CA-2137488-A1 (CA)
Inventor: BAUM RICHARD I
IPC: G06F9/46
Filed: 1994-12-07
Abstract: A coexecutor for executing functions offloaded from central processors (CPs) in a data processing system, as requested by one or more executing controlprograms, which include a host operating system (host OS), and subsystem programs and applications executing under the host OS.   The offloaded functions are embodied in code modules.  Code modules execute in the coexecutor in parallel with non-offloaded functions being executed by the CPs.  Thus, the CPs do not need to execute functions which can be executed by the coexecutor.  CP requests to the coexecutor specify the code modules which are accessed by the coexecutor from host shared storage under the same constraints and access limitations as the control programs.  The coexecutor may emulate host dynamic address translation, and may use a provided host storage key in accessing host storage.   The restricted access operating state for the coexecutor maintains data integrity. Coexecutors  can  be  of  the  same  architecture  or  of  a  totally  differentarchitecture from the CPs to provide an efficient processing environment for theoffloaded functions.  The coexecutor interfaces host software which provides therequests to the coexecutor.  Offloaded modules, once accessed by the coexecutor,may be cached in coexecutor local storage for use by future requests to allow subsequent invocations to proceed without waiting to again load the same module.

The film may be bonded to the first sheet or it may be free. The present invention also provides a method of packaging produce involving the use of this packaging material.
Patent CA-2146671-A1 (CA)
Inventor: HULKKONEN SEPPO
IPC: F26B21/04
Filed: 1993-09-15
Abstract: A method and configuration suited to feeding a water-containing fuel such as peat or brown coal into a pressurized space such as a pressurized dryer (2) or a high-pressure gasifier. A fuel with a high moisture con-tent requires drying in a dryer (2) prior to gasification or combustion. In the dryer the fuel dewatered, whereby the separated water is discharged as steam from the dryer. The generated steam is separated from the fuel flow exit-ing the dryer (2) and it can be routed as injection steam to a gas turbine (14). When a portion (21) of the steam extracted from the fuel flow exiting the dryer (2) is fed into the fuel entering the dryer (2) or to a heat exchanger (25), which is employed for heating the fuel flow, a fuel of higher moisture content can be fed into the dryer (2), or alternatively, the moisture content of the fuel can be increased to improve the feed of the fuel. The method imparts no reduction of the economy of the energy gen-eration process.

Title: Knowledge base management system with dependency information for procedural tests
Inventor: MCGUINNESS DEBORAH L
IPC: G06F9/44
Filed: 1995-04-27
Abstract: A knowledge representation system which allows a user to generate, maintain and access information in a knowledge base using a description language is disclosed. The knowledge representation system maintains the dependency relationships between the different objects that are stored in the knowledge base so that pieces of information that are related to or dependent upon added or updated information may be properly classified at all times. The knowledge representation system includes a mechanism for processing dependency information that is returned from user-defined test functions in order to accurately maintain the dependency information implicated upon execution of the user-defined procedural test functions. A subsumption function determines if a particular individual in the knowledge base satisfies a concept.  The subsumption function evaluates each component of a concept description and maintains the dependency information implicated by the concept component. A test restriction evaluation subroutine determines whether test restriction components of the concept are satisfied and processes the dependency information that is returned from the user-defined procedural test functions.

Filed: 1995-05-24
Abstract: An active adaptive control system introduces a control signal from an output transducer (14) to combine with the system input signal (6) and yield a system output signal (8).  An error transducer (16) senses the system output signal and provides an error signal (44). An adaptive filter model (40) has a model input from a reference signal (42) correlated to the system input signal, and an output outputting a correction signal (46) to the output transducer to introduce the control signal according to a weight update signal (74) provided by the product (from multiplier 72) of the reference signal and the error signal.  Selective leakage of the weight update signal is provided in response to a given condition of a given parameter, preferably output power of the correc-tion signal, to control performance of the model, to selectively degrade same according to need.  Leakage is varied by multiplying a previous weight update value by a factor .gamma. and adding the result to the product of the reference signal and error signal, and varying .gamma. as a function of the correction signal.
