Title: System design tool and method
Inventor: JOHNSTON TERENCE M
IPC: G06F9/44
Filed: 1989-10-05
Abstract: SYSTEM DESIGN TOOL AND METHOD            ABSTRACT:  A system design tool and a method for use in system design, by which the behaviour of a complex interactive system can be simulated.  The system is represented as a number of interconnected "processes" (e.g. 7,8,14) and each process is provided with an algorithm to model its function and its interconnections (1,2).  The processes may be arranged in a layered hierarchical structure (4,6,9) and each process can have functions such as supplying data from a sensor, relaying data or processing data.  The algorithms are combined into an overall model of the system, and the system model is supplied with data on initial conditions of the system. The system model (for example, a computer program) is then executed using the data on initial conditions so as to perform a simulation of the system, with additional data being supplied during execution to simulate changes in external conditions affecting the system.  The progress of the simulation can be monitored on a display which shows a logic diagram representing at least part of the system, with symbols representing individual processes which change colour, or change in some other way, to show whether the respective process is inactive, transmitting data, processing data or the like.  This allows potential bottlenecks or other problem areas in the system to be identified.          The system design tool and method can be applied to a wide range of interactive systems, such as transport systems, telecommunications networks, chemical plant and so forth.

Abstract: The present invention relates to a method and apparatus for reducing the test cycle time and for improving the measuring accuracy of a leak testing process of a container. The process comprises the steps of providing a pressure difference as an initial predetermined pressure between the exterior of a closed container and the interior of the closed container without destroying the integrity of the container. The pressure exterior to the sealed container is measured for a certain time. This measurement determines the pressure integrity of the closed container. The method also includes the step of minimizing the volume of the exterior of the closed container wherein the size of that volume determines the test cycle time and the measuring accuracy. The invention further comprises a test chamber which is closable and contains a cavity for introducing the container under test. A means is provided for installing or introducing a pressure difference at an initial predetermined value between the exterior of the container under test and the interior of the cavity. A measuring unit is provided for measuring the pressure value which is dependent on the pressure difference and the leakage of the container. The shape of the cavity is at least substantially geometrically similar to the shape of the container so as to minimize the volume of the cavity outside the sealed container under test.

Inventor: HUC ALAIN
IPC: A61K47/42
Filed: 1990-01-31
Abstract: The invention relates to microcapsules with a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, and to processes for the manufacture of the said microcapsules.      According to the invention, the microcapsules comprise a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, the proportion of polyholosides, for example glycosaminoglycans, relative to the atelocollagen preferably being between 18 and 50% by weight. These microcapsules can be manufactured either by a process involving interfacial cross-linking or by the extrusion of a laminar flow which is broken up by vibrations into individual droplets, which fall into a crosslinking bath.      These microcapsules are biocompatible by virtue of the presence of atelocollagen, which has most of the advantageous properties of collagen, namely a very low antigenicity and a perfect biodegradability. They are therefore particularly suitable for the manufacture of cosmetic, pharmaceutical or food compositions.
