Patent CA-2216226-A1 (CA)
Title: Apparatus and method for cultivating molluscs
Inventor: GRAHAM ROBERT
IPC: A01K61/54
Filed: 1996-04-09
Abstract: The invention relates to an apparatus for cultivating molluscs. The apparatus comprises a rotatably supported container for cultivating molluscs therein; a buoyancy member responsive to water level change; a pivotably mounted lever connected to the buoyancy member; and means to effect rotational movement of the container in response to movement of the buoyancy member and the lever so that, in use, the molluscs tumble in the container. The invention also relates to a method for cultivating molluscs. The method comprises the steps of placing molluscs to be cultivated in a rotatably supported container; and at least partially rotating the container in a first direction in response to a water level change, so as to tumble the molluscs in the container.
Patent CA-2221944-A1 (CA)
Title: Air purifier
Inventor: BRAIS NORMAND
IPC: F24F8/26
Filed: 1997-11-24
Abstract: Disclosed is a chemical and biological air purifier. The air purifier has a housing having an inlet and an outlet both aligned on a longitudinal axis, a turbulence generator, one or more vacuum ultraviolet (UV) sources achieving a chemical purification and one or more germicidal ultraviolet (UV) sources achieving the biological purification.      The turbulence generator is mounted within the housing downstream of the inlet and promotes a dispersion and mixing of air received through the inlet. The vacuum UV source is mounted within the housing downstream of the turbulence generator and breaks oxygen molecules into mono-atomic oxygen which then reacts with chemical contaminants present in the air and degrades them by successive oxidation to odourless and inoffensive byproducts. The turbulence generator reduces the production of ozone by increasing the contact between the mono-atomic oxygen and the chemical contaminants. The germicidal UV-C source is mounted within the housing parallel to the longitudinal axis of the housing downstream of the vacuum UV source. The germicidal UV-C source, in use, kills biological contaminants present in the air by irradiation and degrades residual ozone produced by the vacuum UV sources into molecular oxygen, thereby purifying air from the biological contaminants and residual ozone.
Patent CA-2222159-A1 (CA)
Title: Fiber optic ribbon cable assembly and method for its manufacture
Inventor: SMITH TERRY L
IPC: G02B6/38
Filed: 1996-05-07
Abstract: A fiber optic ribbon cable has optical connector assemblies and release elements manufactured in line with the ribbon cable assembly so as to provide a fixed, lateral spacing of the optical fibers relative to each other within the connector assembly and has the remaining portion of the cable manufactured whith an arbitrary lateral spacing of the optical fibers relative to each other. A pair of adhesive tape layers are sandwiched around the optical fibers, release elements and in-line optical connector assemblies. The release elements provide access points to the optical fibers for easy application of a connector in the field. To equip the cable with a connector, the cable is cut near the midpoint of one of the access points. After the cable is cut, the adhesive tape layers and the release element may be easily peeled back exposing the optical fibers.

Title: Application of a polymer backing onto a glass substrate
Inventor: NELSON DOUGLAS M
IPC: C09J163/00
Filed: 1996-06-05
Abstract: A method of forming a polymer backing on a glass substrate through the use of a pre-polymer powder applied onto the surface of the substrate. The backing is applied on-line in an existing substrate manufacturing or fabricating process while the substrate is at a high enough temperature to polymerize the powder. The resulting backed substrate is durable and abrasion resistant and exhibits excellent opacification and adhesion properties. The polymer backed substrate ideally finds use as a mirror.

Patent CA-2224901-A1 (CA)
Title: Method for conditioning fluidised bed combustor ashes
Inventor: ANTHONY EDWARD J
IPC: C04B2/06
Filed: 1997-12-15
Abstract: A process for hydrating CaO residues in fluidised bed combustor ashes that both achieves a better level of hydration, which does not add significantly to the cost of the hydration process, which reduces the consumption of water in the hydration process, and which if desired can trap at least some of the CO2 in the furnace gasses, by using some of it to convert the hydrated CaO to CaCO3. This both reduces the amount of CO2 released to the atmosphere, and converts the potentially dangerous Ca0 in the ashes into an effectively inert and benign material. The hydration reaction between the solid CaO containing ashes and water is activated sonochemically. By exposing the ash/water mixture to sound under the correct conditions of frequency, and power input it is possible to improve both the rate of hydration, and the level of hydration, of FBC ashes. The process can be carried out either batchwise or continuously, and does not require an extended time period.

Title: Distributing network services and resources in a mobile communications network
Inventor: LIU GEORGE
IPC: H04W28/18
Filed: 1996-07-03
Abstract: A full mobility data network architecture and method supports global wireless mobile data accessing. A Mobile Distributed System Platform, a mobility agent and a mobile-floating agent are provided for supporting service and resource mobility, and for distributing network services and resources closer to mobile users. In one aspect of the invention, a predictive mobility management algorithm determines where a mobile user or terminal is likely to be. Mobile-floating agents are then established at these locations to permit pre-connection and pre-arrangement of network services and resources for use by the user upon arrival. This allows mobile networks to more intelligently and dynamically provide services to mobile users. The Mobile-Floating Agent scheme can be used, for example, to build a mobile virtual distributed home location register (HLR) and visitor location register (VLR) in personal communication networks (PCNs), in order to reduce the call set up time. It can also be used for "soft data structure handover" for mobile computing.

Title: Alternator for an automotive vehicle
Inventor: UMEDA ATSUSHI
IPC: H02K3/34
Filed: 1998-03-04
Abstract: The present invention provides a compact, efficient and noiseless alternator for an automotive vehicle which employs a double-layer coil arrangement in a slot for eliminating a coil end interference as well as improving a space factor. An automotive alternator comprises a Lundel-type core rotor with 16 poles, and a stator with toothed portions of 96 pole spaced by slots. U-shaped conductor segments are installed in the slots. One portion of the conductor is accommodated in an outer layer portion of a predetermined slot, while the other portion is accommodated in an inner layer portion of a slot phase shifted by an electric angle of 180°. In this manner, all of the slots are separated into the inner and outer layers to accommodate a plurality of conductor segments. These conductor segments are connected only at one side of the stator to form a total of twelve wavy winding coils. These twelve wavy winding coils are divided into three groups each consisting of a serial connection of four wavy windings to constitute one phase of a three-phase stator coil.

Title: Socket weld apparatus and method
Inventor: KHATCHADOURIAN VAROUJ
IPC: B23K31/02
Filed: 1998-12-23
Abstract: A socket welding apparatus is used in welding a pipe or other object into a socket. The apparatus includes a peripheral groove in the socket spaced from the outer end of the socket and from the bottom of the socket. A stopper is engaged in the groove and projects from the groove into the socket to form a stopper for the end of the pipe. The stopper is made contractible, as by forming it as a split ring, which may be a flat washer with a through slot or a circular section ring. As the pipe or other object is being welded into the socket, the thermal expansion of the object will push the stopper out of the groove to reduce stresses that would otherwise be applied to the weld, reducing the weld quality and leading to weld cracks.
