Patent CA-2135569-C (CA)
Title: Self-sealing flexible elastomeric valve and trocar assembly for incorporating same
Inventor: DURMAN BERNARD J
IPC: A61M39/04
Filed: 1994-11-10
Granted: 2006-08-15
Abstract: A self sealing flexible elastomeric valve is disclosed. The valve can be used to seal a trocar device from loss of gas pressure during a laparoscopic surgical procedure when a surgical instrument is inserted therethrough as well as when no instrument is inserted. The preferred one piece valve includes a flange having an aperture, and a cylindrical wall section which extends to a pair of mutually opposed sealing wall sections defining a generally S-shaped slit. This slit configuration at the end of these wall sections define the sealing surfaces. The flange preferably includes a concentrically dome shaped region with the aperture centrally displayed. The valve also is preferably composed of a silicone rubber.      The valve has the advantages of simplicity of manufacture and assembly and the ability to provide an adequate seal against the surface of any surgical instrument inserted through it. Also, the improved valve will require a small amount of force to insert instruments and will resist eversion of the valve walls when instruments are withdrawn.      A trocar assembly incorporating the sealing valve as described above is also disclosed.

Title: Determination of the extent of cross-linking prior to the intentional curing of polymers
Inventor: STRONG A BRENT
IPC: G01N33/44
Filed: 1993-09-20
Granted: 2003-12-16
Abstract: Detection of the extent of cross-linking of a high impedance polymer material during a pre-cure stage is disclosed. The sen-sor inputs a test signal (20) to the polymer material (21) and a fixed resistance reference material (22) to generate an output vol-tage (27) which is indicative of the impedance of the sample. The initial output adopted as a reference and subsequent voltage dif-ferences are taken as a relative indicator of the extent of cross-linking which has occurred within the polymer material.

Title: Apparatus for forming a fill line in a paper cup
Inventor: RIDOUT JOHN
IPC: B27N5/02
Filed: 1995-11-16
Granted: 2001-07-03
Abstract: A simple apparatus for forming a fill line in a paper beverage container such as a paper cup is disclosed. The apparatus includes no moving parts. A fill line is formed by forcing a punch of a mating ring into a finished cup positioned in a die which includes an annular recess spaced below the rim of the finished cup, the annular recess terminating in a bottom edge which serves as an anvil surface forforming the fill line. The fill line provides a user of the beverage container with a reference point for establishing a consistent measure of volume. The advantage is a simple apparatus adapted to be fitted to most paper cup finishing machines. The apparatus has no moving parts and is therefore not prone to requiring maintenance or replacement.

Title: Packaging systems for increased food product shelf life
Inventor: GORLICH MICHAEL P
IPC: B65B7/16
Filed: 1994-05-16
Granted: 1999-11-02
Abstract: A tray having a peripheral flange with one or more raised ledges to secure a pair of membranes to enclose the tray. A lower membrane may be attached to a first ledge of the flange. An upper membrane may be attached to a second ledge or a recessed lip of the flange without connection to the lower membrane, except through the tray. The two attachment surfaces may be separated by a trough or by being positioned on different levels to facilitate trimming of the upper membrane in a continuous manufacturing process. A method and apparatus for modified atmosphere packaging uses a rotary conveyor to transport a plurality of trays to be packaged between a plurality of stations in a circular arrangement. The trays may be loaded onto a receiving platform by depositing them over movable beds which can reciprocate downwardly in order to permit the trays to be removably held inside slots in a removable platform. Since the platform is removable from the conveyor, it may be centered in any particular station by lifting the platform from the conveyor and guiding it into a precise alignment at a particular station. The package may then be filled, its atmosphere replaced with one lower in oxygen content, and then the desired atomosphere sealed within the package. This can be done in the continuous fashion so that the film is severed from a continuous web. A package, packaging method, and packaging apparatus for facilitating the packaging of large meat products and exchanging the ambient atmosphere to establish a desired gaseous atmosphere that extends the shelf life of the product. The package includes a pair of preformed relatively rigid plastic domed or cupped members which abut along a sealing surface. The upper (318) and lower (310) package portions include flanges (312, 336) which are adapted to facilitate not only the formation of the package but its subsequent opening. A reciprocatable filling tube (330) maintains the separation between the upper and lower package portions to permit gas exchange and then may be reciprocated downwardly to allow the upper package portion to abut atop the lower package portion for sealing connection.

Title: Multimedia collaboration system
Inventor: LUDWIG LESTER F
IPC: G06F13/00
Filed: 1994-10-03
Granted: 2001-02-13
Abstract: A collaboration system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments.  It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of date at intermediate hops, as well as video mosaicing and cut-and-paste technology.
