Patent CA-2299687-A1 (CA)
Inventor: CHAPUT CYRIL
IPC: A61L27/50
Filed: 1998-04-06
Abstract: The present invention relates to a temperature-controlled pH-dependant formation of ionic polysaccharide gels, such as chitosan/organo-phosphate aqueous systems, and methods of preparation thereof. While chitosan aqueous solutions are pH-dependant gelating systems, the addition of a mono-phosphate dibasic salt of polyol or sugar to chitosan aqueous solutions leads to further temperature-controlled pH-dependant gelation. Solid organo-phosphate salts (120 % w/v) are added and dissolved at low temperature (10 ~C) within 0.5 to 4.0 % w/v chitosan in aqueous acidic solutions. Aqueous chitosan/organo-phosphate solutions are initially stored at low temperatures (4 ~C), then endothermally gelated within the temperature range of 30 to 60 ~C. Chitosan/organo-phosphate solutions rapidly turn into gels at the desired gelation temperature. Gelation can be ex vivo within any receivers or molds, or in situ in animals or humans (in vivo) so as to fill a tissue defect or cavity.
Patent CA-2299706-A1 (CA)
Title: Siphon assembly with one way priming valve
Inventor: MALECKI STEVEN JOSEPH
IPC: F04F10/02
Filed: 2000-02-29
Abstract: An improved priming assembly which maybe used for siphoning, includes a siphon tube comprising an inlet end and a discharge end. The discharge end may be connected to a discharge hose that leads to a discharge area. A one-way valve is inserted within the tube adjacent to the inlet end of the tube. The valve comprises a flexible rubber sheath a portion of which is sealed to the inner surface of the tube and which extends toward the discharge end. The sheath is movable from an open position to a closed position. When fluid is caused to flow from the inlet end to the discharge end, the sheath moves to its open position allowing fluid flow. When fluid is caused to flow from the discharge end toward the inlet end, the sheath collapses to the closed position such that it prevents flow of fluid toward the inlet end. Priming of the siphon is created when the sheath collapses into its closed position, under the weight of the fluid as the rigid siphon tube is thrust upwardly. The sheath moves to the open position as the tube moves down within the fluid to be discharged, allowing fluid flow through the valve toward the discharge end, and to accumulate within the tube.
Patent CA-2300599-A1 (CA)
Title: Seismic systems and methods for downhole clock synchronization
Inventor: CHENIN BERTRAND A
IPC: G01V1/44
Filed: 2000-03-14
Abstract: A method and apparatus facilitating the event-synchronized recording of data at different locations, such as may occur at and within a borehole during a Measurement-While-Drilling ("MWD") operations. In a seismic survey the method and apparatus uses three subsystems: 1) a seismic source; 2) a borehole receiver, and 3) a pinger. When used in a borehole containing a drill string, the pinger strikes or vibrates the drill string causing an acoustic signal to traverse the drill string. The signal reaches a borehole receiver where it is detected. The signal is also reflected back up the drill steering to a sensor, nominally an accelerometer sensor, associated with a pinger where it is time-stamped by inclusive timing circuitry. By detecting and recording the round trip travel time of the acoustic signal and using a pulse transmitted from the downhole sensor package, for example, through the drilling mud, remotely occurring events can be synchronized without the use of an electrical connection between the electrically-separated systems recording, time-stamping, and storing the events. Using this method, events time-stamped by clock circuitry located within a borehole sensor package are synchronized to events time-stamped by clock circuitry on the surface to within plus or minus milliseconds or better.
Patent CA-2302015-A1 (CA)
Title: A read-only memory and read-only memory device
Inventor: NORDAL PER-ERIK
IPC: G11C11/56
Filed: 1998-08-28
Abstract: A read-only memory is made electrically addressable over a passive conductor matrix, wherein the volume between intersection of two conductors (2; 4) in the matrix defines a memory cell (5). Data are stored as impedance values in the memory cells. The memory cells (5) comprise either an isolating material (6) which provides high impedance or one or more inorganic or organic semiconductors (9), preferably with an anisotropic conducting property. The semiconductor material (9) forms a diode junction at the interface to a metallic conductor (2; 4) in the matrix. By suitable arrangement of respectively the isolating material (6) and semiconductor material (9) in the memory cells these may be given a determined impedance value which may be read electrically and corresponds to logical values in a binary or multi-valued code. One or more head-only memories (ROM) may be provided on a semiconductor substrate (1) which also comprises driver and control circuits (13), to accomplish a read-only memory device. The device may be realized either planar or also volumetrically by stacking several read-only memories (ROM) in horizontal layers (15) and connecting them with the substrate (1) via addressing buses.
Patent CA-2302578-A1 (CA)
Inventor: YANG C SHU-CHIUNG
IPC: B62M9/10
Filed: 1998-09-03
Abstract: La présente invention concerne un type de structure de moyeu comprenant, pour l'essentiel, un mécanisme d'embrayage constitué par un embrayage et par les dents triangulaires du boîtier de roulement à l'intérieur du moyeu, de façon que l'organe dans son ensemble peut assurer de façon indépendante une fonction de freinage unidirectionnel sans qu'il soit nécessaire d'ajouter des composants comme c'est le cas avec les structures classiques. Dans le cas où l'on souhaite ajouter une fonction supplémentaire de changements de vitesse par paliers, la compatibilité élevée des composants permet de ne remplacer que le support de plateau, et non plus de nombreux composants comme c'était le cas dans les structures classiques, ce qui augmentait les coûts d'assemblage. Vu la tendance actuelle des bicyclettes qui présentent des caractéristiques en constante évolution, la présente invention permet de réduire la nécessité de modifier la taille des composants concernés et par conséquent, de réduire les coûts de production.

Title: Microwave popcorn preparation and serving package
Inventor: SCRIMAGER CYNTHIA
IPC: B65D81/34
Filed: 1998-10-13
Abstract: An expandable microwave popcorn package (1) which contains a charge of popcorn kernels (14) for preparation in a microwave oven. The package (1) is formed of front and back panels (2, 4) preferably joined together at the top and bottom ends by an adhesive and at the sides by side panels (6, 8). The back panel (4) includes a pair of separation lines (18) along which the package material is relatively weak such that a portion (16) of the back panel can be torn from the remainder of the package to expose the popcorn within. Separation lines (18) may be formed by weakening a portion of the bag substrate, by reinforcing the adjacent areas, or by a combination of the two. Side panels (6, 8) are folded to form gussets (7) which allow the package to remain flat during storage, to expand to accommodate the popped kernels. A susceptor (9) is also preferably placed on the front panel (2) opposite the back panel to enhance the popping action.
