Patent CA-2224336-A1 (CA)
Title: Brush section for an electric toothbrush
Inventor: DRIESEN GEORGES
IPC: A61C17/24
Filed: 1996-06-12
Abstract: The invention is directed to a brush section for an electric toothbrush in which a handle section is connectible with the brush section. A disk-shaped bristle carrier at the end of the brush section remote from the handle section has on its upper side bristle tufts disposed on one central ring and one outer ring. The bristle carrier is rotatable about an axis of rotation in an alternating oscillating fashion from a central position.      The axis of rotation is aligned at approximately right angles to a longitudinal center line of the brush section. In use of the electric toothbrush, an improved cleaning action is accomplished in that the outer ring of the bristle carrier is set with tufts of bristles of different lengths. Adjacent tufts on the outer ring form clusters of tufts, each cluster having bristles of a length different from bristles of tufts of at least one other cluster. The arrangements of clusters and tufts are particularly useful in penetrating the interproximal spaces on either side of a tooth.

Title: Method of disgorging flames from a two stream tangential entry nozzle
Inventor: SNYDER TIMOTHY S
IPC: F23R3/12
Filed: 1997-12-19
Abstract: A method of reducing the tendency of the combustion flame to stabilize within the mixing zone of a tangential entry nozzle is disclosed which comprises mixing fuel and air in a mixing zone within a fuel nozzle assembly, thereby producing a first fuel/air mixture which is isolated from the combustion products by maintaining sufficiently high axial velocities throughout the mixing zone and using a combination of a second internal passageway within a centerbody (either fueled or unfueled) and the surfaces of the combustor inlet port
Patent CA-2229618-A1 (CA)
Inventor: SIEBERT ELIZABETH J
IPC: C08J3/03
Filed: 1996-08-07
Abstract: Des résines époxy, en particulier celles à base de bis-phénol A, peuvent constituer le composant polymère principal d'une composition capable de former spontanément un film lorsqu'elle est déposée, tout en restant stable au cours du stockage. Pour cela, la granulométrie de toutes les particules des polymères capables de former un film présentes dans la composition doit satisfaire aux critères suivants: (1) la granulométrie moyenne des particules diffusant la lumière doit être d'au moins 100 nm environ, mais ne pas dépasser 300 nm environ; (2) pas plus de 1,0 % environ en volume des particules diffusant la lumière ne doivent avoir un diamètre supérieur à 450 nm environ; (3) pas plus de 25 % environ en volume des particules diffusant la lumière ne doivent avoir un diamètre supérieur à 250 nm environ; (4) pas plus de 50 % environ en volume des particules diffusant la lumière ne doivent avoir un diamètre supérieur à 200 nm environ; (5) et pas plus de 75 % environ en volume des particules diffusant la lumière ne doivent avoir un diamètre supérieur à 175 nm environ. Ces dispersions peuvent être réalisées d'une manière avantageuse par un procédé en deux étapes, une solution des polymères capables de former un film est d'abord émulsifiée dans de l'eau, pour former une dispersion préliminaire, et cette dispersion préliminaire est ensuite soumise à au moins une opération de réduction de la taille des particules, dans laquelle la dispersion préliminaire est forcée à travers une ouverture étroite.

Patent CA-2234676-A1 (CA)
Title: Ball point fluid-assisted electrocautery device
Inventor: MULIER PETER M J
IPC: A61B18/14
Filed: 1996-10-02
Abstract: An electrocautery device is disclosed. In accordance with one aspect of the invention, the electrocautery electrode/tip is provided with a hollow, conductive tube terminating at its distal end in a ball point type tip. Fluid, preferably conductive fluid, is applied to the proximal end of the hollow electrode/tip, and expelled from the distal end thereof during electrocautery.  The ball point distal tip allows the distal tip to be directly applied to the tissue and "rolled" or slid along the tissue. This allows the distal tip to be moved across the tissue without dragging or snagging on the tissue. In addition, the conductive fluid expelled from the distal tip further lubricates the distal tip as it moves across the tissue. If conductive fluid is used, the conductive fluid emanating from the electrode/tip conducts the RF  electrocautery energy away from the distal tip so that it is primarily the fluid, rather than the distal tip that actually accomplishes the cauterizing of tissue. That is, the fluide serves as a "virtual" electrocautery electrode.  Since it is the fluid, rather than the distal tip that cauterizes, coagulates and ablates, no burns or perforations are made to the tissue, reducing the amount of debris at the site. Also, the flow of fluid through the electrode/tip tends to keep the distal tip clean and cool.

Patent CA-2240529-A1 (CA)
Inventor: TALLURI MADHUSUDHAN
IPC: G06F21/62
Filed: 1998-06-15
Abstract: The present invention pertains to a system and method for performing remote object invocation. A object-oriented computing system includes a number of independent computing nodes that are interconnected via a communications link. The nodes represent client and/or server computers that do not share memory. Each node includes a number of domains having separate address spaces. Each domain includes one or more threads of execution that invoke one or more objects. The object's method can reside in the same domain as the requesting thread, in a different domain within the same node, or in a different domain in another node. A file descriptor is used to represent those objects whose methods reside in a different domain than the requesting thread. A file descriptor is a protected kernel entity that enables a thread to invoke an object. A thread can only access those objects forwhich it has received an associated file descriptor. An Object Request Broker (ORB) services the object invocation requests for those objects residing in different domains. The ORB provides a mechanism that translates the file descriptor used to reference an object in one domain into the file descriptor used to invoke the object in the domain having the object's method.

Title: Systems and methods for executing application programs from a memory device linked to a server
Inventor: DOMENIKOS GEORGE C
IPC: G06F9/445
Filed: 1997-03-14
Abstract: A computer (12) to connect to a server (14) of an Internet site for executing an application program that is stored on a disk (14a, 14b) linked to the server. Processes transport from the server a server address signal representative of a network address of the server, and a path name signal representative of a file system that includes an application program. The process further generates a mount request as a function of the path name signal and transports the mount request to the server to direct the server to provide an array of server file pointers that point to a file descriptor representative of the file system that includes the application program. The processes provide an array of remote file pointers to a program loader that transports a file block associated with the selected remote file pointer from the disk at the server site to a local program memory element. Process requests may be translated into HTTP compliant commands.

Patent CA-2249140-A1 (CA)
Inventor: SAKAMOTO SHIZUO
IPC: G06K9/00
Filed: 1998-10-01
Abstract: A method and apparatus is provided for object detection and background removal, and also storage media for storing a program which enables automatic detection of an object minutely and with high precision for obtaining an outline. A sectional image statistic calculation measure calculates a mean value and standard deviation of characteristic value of brightness of the sectional image, with the input image being subjected to division processing into sectional image. A  background sectional image selection measure causes a sectional image whose standard deviation is the smallest value in the sectional images to be taken as the sectional image with a high probability of including only the background. A background statistic estimation measure investigates the sectional image, including only the background, and another sectional image under the relationship between the mean value and the standard deviation. This investigation is implemented in terms of whole sectional images, a threshold generation object detection and background removal measure discriminates the background and the detected target object based on predetermined calculation procedure. A second threshold is in use, and is obtained in such a way that the standard deviation multiplied by the constant number given beforehand from the mean value is added thereto.
