Patent CA-2271433-A1 (CA)
Inventor: BRANDON HARVEY
IPC: G09F3/20
Filed: 1999-05-10
Abstract: A label holder for displaying information-containing non-adhesive labels or signs on a channel member at the front of a variety of forms of merchandise shelves in a supermarket or the like, particularly adapted for secure support and ready attachment to both Streator and Lozier type shelf systems wherein the height and configuration of the channel members are different. The label holder may be a co-extrusion of an opaque body panel and a transparent cover resiliently connected along their lower edges to define a label-receiving pocket therebetween. An upwardly and rearwardly extending leg member is integral with the rear of the body panel and underlies and extends behind the channel member. A lower finger is also carried by the rear of the body panel and is biasingly engaged with the upper surface of the lower flange of the channel member. An upper finger is provided on the upper edge of the body panel and is biasingly engaged with the lower surface of the upper flange of the channel member. The upper finger can be collapsed to permit the label holder to be readily engaged within the more closely spaced and prominently defined flanges or lips forming a C-channel on Lozier-type shelves, while expanding to securely engage the label holder between the more widely spaced and less distinctive flanges of Streator-type shelves.

Patent CA-2273284-A1 (CA)
Inventor: FITTS JAMES RUSSELL JR
IPC: B32B25/16
Filed: 1998-10-02
Abstract: La présente invention concerne un stratifié non tissé à alimentation en continu présentant des propriétés élastiques améliorées à la température corporelle. Le stratifié comprend au moins une première et une deuxième couche non élastiques entre lesquelles est intercalée au moins une couche élastique, la couche élastique étant formée d'un copolymère tribloc de polystyrène-poly(éthylène/propylène)-polystyrène ("SEPS") possédant un poids moléculaire moyen en nombre de 81,000g/mol environ. Le pourcentage en poids du styrène est d'environ 18 % et le pourcentage en poids de l'éthylène/propylène est d'environ 82 %. L'augmentation de poids moléculaire dans le bloc EP, tout en permettant de garder le poids moléculaire du bloc de styrène constant, augmente la densité d'entremêlement, la longueur de persistance de la chaîne polymère et le temps de relaxation. En conséquence, la vitesse de désintégration de la charge de stratifié et les mesures de perte de charge sur une période de 12 heures à la température corporelle ont été nettement améliorées par rapport aux stratifiés connus à liaison par étirage de filament continu. Le stratifié s'utilise notamment comme matière de panneau latéral dans des culottes de propreté en raison de sa résistance à l'affaissement à la température corporelle.

Patent CA-2295664-A1 (CA)
Inventor: TANAKA MAKOTO
IPC: A63F13/23
Filed: 1999-05-17
Abstract: This invention concerns an external operation device and makes it possible to conduct communication at a faster rate than previously. The operation means is connected to the operation object via an optical fiber and by converting the electrical signals of the transmission object to optical signals during communication and transmitting said optical signals via optical fibers, even if the frequency is high, no electromagnetic-wave noise is generated as happens when the operation means is connected to the operation object via electrically conductive wires. Thus there is no need to limit the frequency of the optical signals, that is, the communication speed, and therefore communication can be done at a faster rate than previously.

Title: Apparatus and method of splicing digital video streams
Inventor: GAZIT HILLEL
IPC: H04N21/234
Filed: 1999-04-02
Abstract: A splicing system includes a splicer for seamlessly splicing together digitally encoded data streams. In a preferred embodiment, the splicer preferably parses successive splice buffers of data stream data for a splice-out point and a splice-in point, closing an initial GOP if needed. The preferred splicer further finds a new data stream real-time PCR value for aligning new data stream decode/presentation, and aligns the new data stream start time. Concurrently, the splicer preferably uses a frame table to detect overflow and corrects such overflow by adding null packets, thereby delaying portions of data stream data. The splicer also preferably restores data stream encoding by deleting null packets, and thereby accelerating a portion of data stream data. In a further preferred embodiment, the splicer preferably uses a bit-clock schedule offset to delay or accelerate portions of data stream data.

Patent CA-2299472-A1 (CA)
Inventor: HYING CHRISTIAN
IPC: B01D53/22
Filed: 1999-03-20
Abstract: The invention relates to a hydrophobic permeable composite, to a method for producing a hydrophobic permeable composite and to the use of said composite in various processes. Hydrophobic, permeable materials have been known for some time. Plastic materials especially, for example Gore-Tex, but also materials consisting of other organic polymers are used whenever a material is required to be gas- and steam-permeable but not liquid-permeable. These materials have the disadvantage that they can only be used within a certain temperature range. The inventive composite is characterised by a higher temperature resistance since it consists mainly of inorganic materials. It is also relatively easy to produce since it can be obtained using the sol-gel technique. The inventive composite can be used as a membrane in the oxidation of aromatics, for example in the direct oxidation of benzene to phenol.

Title: Closed circuit heat exchange system and method with reduced water consumption
Inventor: KORENIC BRANISLAV
IPC: F28D5/02
Filed: 2000-03-08
Abstract: A system and methods of extracting heat are disclosed. The system may be arranged as a fluid cooler or as a fluid condenser. Three heat exchange sections are provided: a dry indirect contact heat exchange section; a second indirect contact heat exchange section that is operable in either a wet or dry mode; and a direct contact heat exchange section. As a fluid cooler, a connecting flow path connects the dry indirect contact heat exchange section to the second indirect contact heat exchange section. A bypass flow path extends from the dry indirect contact heat exchange section to the process fluid outlet. A modulating valve is at the outlet so that process fluid can be selectively drawn from the dry indirect contact heat exchange section alone, from the second indirect contact heat exchange section in series with the dry indirect contact heat exchange section, or from both the dry and second indirect contact heat exchange sections and mixed. Separate air streams pass through the second indirect and direct contact heat exchange sections before entering the dry indirect contact heat exchange section. As a condenser, process fluid is directed to the dry indirect contact heat exchange section alone or to the dry and second indirect contact heat exchange sections in parallel by valves in the process fluid supply lines. In another embodiment, the process fluid flows in series from the dry to the second indirect contact heat exchange section. The system is operable in different modes to extract heat from the process fluid in the most efficient way with respect to annual water consumption. At low temperatures, the system operates dry with primary heat extraction performed by the dry indirect contact heat exchange section. At higher temperatures, the air streams may be adiabatically saturated with evaporative liquid to pre-cool them below the dry bulb temperature before entering the dry indirect contact heat exchange section. At still higher temperatures, the apparatus may be operated in a wet mode with the primary heat extraction performed by the second indirect contact heat exchange section. Heat is extracted from the process fluid while selectively distributing or not distributing the evaporative liquid over the second indirect contact heat exchange section. Plume formation is prevented since discharge air is heated in contact with the dry indirect contact heat exchange section before leaving the heat exchange apparatus.
