Patent CA-2229396-A1 (CA)
Inventor: ZLIPKO DENNIS
IPC: G01F23/40
Filed: 1998-02-11
Abstract: The invention provides an improved float and float system for use in the monitoring of fluid levels, particularly in small diameter wells by way of a cable and float system. The float system includes a number of centralizers which hold the float cable near the center of the well casing and thus reduce the friction of the cable on the casing walls. The addition of weights on the float cable, either or both below the float and between the float and the top of the well casing, can improve the accuracy and operation of the system even further. A truncated cone-shaped float is provided, with a number of fins displaced evenly around the circumference of the float.
Patent CA-2229497-A1 (CA)
Inventor: MILLER VAN
IPC: A23C9/15
Filed: 1998-02-11
Abstract: A reduced-fat dairy spread which is spreadable at refrigeration temperature, has the appearance, flavour, consistency, rheology, and mouth-feel which is similar to conventional butter. The dairy spread has a formulation which comprises zero up to 43% by weight of butterfat, 30% up to 75% by weight of water, 5% up to 30% by weight of milk solids, and zero to trace amounts of each of a butter culture, salt, and approved butter colours which are compatible with butter, as well as zero to trace amounts of lecithin, potassium sorbate, sodium benzoate, and citric acid. The soft but solid appearance, and refrigeration temperature spreadability, of the dairy spread is achieved as a consequence of protein coagulation at elevated temperatures of a stirred mixture of the starting materials. The liquid starting materials, heavy cream or milk, are unhomogenized; homogenization of the mixture does not occur until after protein coagulation at elevated temperatures has taken place. When the reduced-fat dairy spread is made, the water content is bound by the protein constituents of the milk solids, and is in a continuous phase dispersion. On the other hand, the butterfat is in a discontinuous phase, suspended in the continuous phase dispersion.

Title: Improving the adhesion between rubber components
Inventor: HSU WEN-LIANG
IPC: C08L21/00
Filed: 1998-05-12
Abstract: IMPROVING THE ADHESION BETWEEN RUBBER COMPONENTS      The process of this invention can be utilized to improve the adhesion between rubber components. It is generally most useful for improving the adhesion between two different pre-cured rubber components or for improving the adhesion between a pre-cured rubber component and an uncured (green) rubber component. However, the technique of this invention can also be employed to improve the adhesion between two uncured rubber components.  The technique of this invention is based upon the unexpected discovery that low molecular weight trans-1,4-polybutadiene containing rubber compounds can be used to improve the adhesion between rubber components.  This invention more specifically reveals a technique for improving the adhesion between a first rubber component and a second rubber component in a process for manufacturing a cured rubber article, said technique comprising the steps of:  (1) positioning a layer of an adhesion-promoting rubber composition which is comprised of a low molecular weight trans-1,4-polybutadiene rubber between the first rubber component and the second rubber component,  (2) bringing the first rubber component into contact with one side of the layer of adhesion-promoting rubber composition and bringing the second rubber composition into contact with the other side of the layer of adhesion-promoting rubber composition and (3) curing the first rubber composition, the second rubber composition and the adhesion-promoting rubber composition together under conditions of heat and pressure to produce the cured rubber article.

Title: Chest retractor for performing cardiac surgery
Inventor: CARTIER RAYMOND
IPC: A61B17/00
Filed: 1998-06-26
Abstract: A chest retractor for performing cardiac surgery on the coronary organs of the patient, comprising a movable input means to which the surgeon input is applied in the form of a mechanical force or torque, a contacting means which interfaces and retracts the patient's thoracic structure TS when surgeon input is applied to said movable input means, and a surgeon input load-reducing means or surgeon input load-normalizing means provided in at least one mechanical interface between chest retractor components where relative motion occurs. The load-reducing and load-normalizing means are preferably non-lubricated in order to ensure inert and sterile environment during surgery. In certain embodiments, the chest retractor is comprised of a locking means which provides a continuous variable range of substantially-stable lockable open positions of retractor arms. The chest retractor according to this invention improves the efficiency and safety of cardiac surgery by reducing the surgeon input required to achieve retraction, and by allowing said input to be applied more uniformly and in a controlled manner free from sudden movements through the normalization of chest retractor variables.
Patent CA-2239619-A1 (CA)
Title: Method and apparatus for side pumping an optical fiber
Inventor: GOLDBERG LEW
IPC: H04B10/291
Filed: 1996-12-09
Abstract: A technique for the efficient coupling of pump light into a fiber (19) by injecting the light through the side of a fiber leaving the fiber ends accessible to input and output coupling. This technique relies on the fabrication of a groove (18) or a microprism into the side of the fiber. The groove shape is adapted effective to the variables of light wavelength, orientation of the source and visible relating to fiber construction so as to allow the efficient injection of pump light. Light emerging from a laser diode or other suitable means (16) for launching light placed on the opposite side of the fiber, and in proximity to the fiber wall, propagates laterally through the fiber and impinges on the sides of the groove (18). The vertical rays impinging on the groove facets are specularly reflected and directed along the horizontal fiber axis of the outer core. By employing a reflective coating on the groove (18), the reflectivity of the groove facets approach 100% for a wide range of incidence angle. In this manner one can launch external optical signals into an optical fiber (19).

Abstract: A broadband customer premises equipment ("CPE") interface device (100) interfaces with conventional telephones (152), screen phones (154), and broadband data and video devices. The interface device includes circuitry to connect with a telephone network (102) via a first telephone connection (104) and circuitry to connect with a broadband network (106) via a second, broadband connection (108). In addition, the interface device (100) includes ADSI off-hook alerting ("AOHA") circuitry and adds ADSI script management server ("ASMS") circuitry to provide noninvasive programming of screen phone-type CPE devices (154). ASMS programming information for a CPE device is transferred to the interface device (100) via the broadband network (106) and stored in the interface device. The AOHA and ASMS circuitry requests the CPE  device (154) to go off-hook when idle, without ringing the CPE device (154) like a conventional telephone call. When the CPE (154) is idle, the AOHA and ASMS circuitry routes the programming information from storage (142) into the CPE (154).

Abstract: Des matériaux répartissant les fluides sont particulièrement utiles dans des structures à noyau absorbant utilisées dans des articles absorbants jetables tels que les couches pour bébés, les produits pour incontinents et les serviettes hygiéniques. Un traitement mécanique d'un matériau répartissant les fluides permet d'améliorer les propriétés d'inhibition par capillarité dans le sens préféré de répartition des fluides. Ce traitement mécanique consiste pour l'essentiel à alimenter l'espace entre deux rouleaux cannelés (21, 25) avec une bande (1) de matériau répartissant les fluides. Chaque rouleau cannelé (21, 25) possède des nervures (35) et des sillons (31) circulaires, qui s'engrènent. La largeur des nervures (35) et celle des sillons (31) dépendent de l'épaisseur de la bande (1); il est possible d'ajuster le degré de recouvrement (39) des nervures opposées (35) en fonction du degré de traitement mécanique.
