Inventor: AULT PATRICK L
IPC: C03C25/14
Filed: 1995-11-27
Abstract: A method for fiberizing mineral material (18) with organic material (38) includes centrifuging mineral fibers (20) from molten mineral material (18) with a first spinner (10) rotating about an axis (12), changing the direction of the mineral fibers (20) to form a downwardly moving veil (26) of mineral fibers (20), establishing a flow of molten organic material (38) moving downwardly in a first conduit (36) positioned within the veil (26), and directing the flow of molten organic material (38) to a position beneath the spinner (10), dividing the flow of molten organic material (38) into a plurality of streams, directing, by means of individual conduits (28), individual ones of the plurality of streams radially outwardly away from the first conduit (36), rotating the individual conduits (28) about the axis (12), centrifuging organic fibers (56) from the molten organic material (38) by means of nozzles (46) at the radially outward ends of the individual conduits (28), and directing the organic fibers (56) into contact with the veil (26) of mineral fibers (20).

Title: Insecticidally-active composition
Inventor: NELSON KURT D
IPC: A01N53/00
Filed: 1996-01-24
Abstract: An insecticidally-active composition that forms an oil-out emulsion of limited stability containing an aqueous phase and an oil phase. When this composition is sprayed onto a target surface, the aqueous phase separates out at least partially from the oil phase in the air or upon hitting a target surface.  Accordingly, this composition does not leave unsightly milky residues.  Moreover, it is highly effective in killing insects.

Patent CA-2212347-A1 (CA)
Title: Sand bag maker
Inventor: STASHICK DANIEL A
IPC: B65B9/20
Filed: 1997-08-01
Abstract: In response to an environmental disaster, such as flooding, or hazardous material spills, a large amount of resources need to be organized and mobilized quickly and effectively.  The response effort can involve thousands of volunteers, military personnel, vehicles and equipment.  Many hours and even days can be spent manually filling sandbags or absorbent booms placing them into dikes, maintaining and upgrading the barrier, and containing spilled materials.  The Barrex system automates the process of sandbag or absorbent boom sewing, filling and placement.  It allows a small crew to produce a continuous barrier and place it in the form of a dike, or a protective or absorbing boom, eliminating the need for thousands of man hours of work.  The process involves forcing the aggregate material into the tube through a forming channel.  The wrapping material is folded over the channel in a circular fashion, to the form of a tube.  The two edges are then joined to form the tube into which the aggregate material is forced.       The tube is then laid in the appropriate position by a movable chute.

Title: Iso drain
Inventor: FORTIER DENIS
IPC: E04H4/12
Filed: 1997-09-18
Abstract: Depuis toujours, les propriétaires de piscine creusée installent un drain de fon d à leur piscine. Ledit drain de fond est stabilisé avec du béton dur et installé à plus de huit (8) pieds de profondeur et donc, par le fait même, à l'épreuve des variatio ns de température du sol et notamment, du gel et du dégel. Depuis quelques années seulement, des drains de fond sont également installés da ns les piscines hors terre. Aucun devis d'installation et/ou de plan d'installation n'est cependant disponible pour un tel drain. Le fond de la piscine étant constitué de matériel mou et flexible, tel le sable et la poussière de roche, ce dernier n'of fre pas la stabilité voulue et le drain de fond se doit d'être stabilisé. De plus, compt e tenu que le drain de fond est installé en surface, les mouvements de sol provoqués pa r le gel et le dégel répétés peuvent avoir comme résultat un déplacement du drain de fond et ce, même si le drain de fond est entouré de béton dur pour en assurer sa stabilité. L'augmentation de la surface occupée par le drain de fond lors de la pose de l'I SO DRAIN aide à pallier à l'affaissement du sol et en augmente la stabilité. De plu s, le styromousse aide à pallier au déplacement du drain de fond causé par le gel et l e dégel. L'invention de forme circulaire est fabriquée de mousse de polystyrène résistant aux changements multiples de température.

Title: Therapeutic fragments of von willebrand factor
Inventor: HRINDA MICHAEL E
IPC: C07K14/745
Filed: 1996-06-06
Abstract: Processes for preparing aqueous solutions of cysteine--altered von Willebrand Factor fragment which are substantially free of aggregate and capable of therapeutic use for treating thrombosis are provided.

Patent CA-2224926-A1 (CA)
Inventor: RAST ROBERT
IPC: H04N7/173
Filed: 1997-12-16
Abstract: A television viewer can easily navigate programs which are grouped according to a common service provider or other grouping criteria by depressing the "channel up" or "channel down" buttons on a hand-held remote control. Programming services which are provided via one or more transmission paths are integrated, thereby allowing a viewer to successively select the grouped channels regardless of the broadcast signal, transmission path, frequency spectrum, transport stream and/or PID in which the channel is carried. Data is provided with broadcast signals to indicate broadcast address information which corresponds to a primary channel and one or more secondary channels of a channel group. A viewer can successively view the channels of the group while bypassing intermediate non-group channels. Grouped channels can thus be designated by a common channel designator such as a channel number. Goodwill and brand loyalty which has been built up over time in a local station channel number can be used to define a family of programs to maintain continuity as channels are added or dropped, or channel assignments of programming services are rearranged.

Title: Foldable agricultural roller
Inventor: BERNIER ANDRE
IPC: A01B73/02
Filed: 1998-05-11
Abstract: The agricultural roller has three rolls mounted in a triangular overlapping operable configuration. The wing rolls are movable about a pair of spaced-apart transversal articulations between the wing roll frameworks and a central framework enclosing the central roll. The transversal articulations are positioned near a respective end of the central roll such that adjacent roll ends move up and down in unison. The central framework is also movable about a longitudinal articulation across the rear end of a trailer frame. The diameter of the central roll is larger than the diameter of wheels on the trailer frame such that the wheels are raisable off the ground when the rolls are deployed in an operable mode. In a towable configuration, the central roll is moved above the trailer frame and the wing rolls are moved above the central roll with their respective axes aligned forwardly.

Title: Method and apparatus for intraosseous infusion and aspiration using an automatic release mechanism
Inventor: JACOBS MICHAEL W
IPC: A61M5/42
Filed: 1998-05-15
Abstract: This invention relates to an apparatus and method for infusing fluids to and aspirating tissue from an intraosseous site. The apparatus is comprised of an infusion tube coupled to an introducer with a release mechanism that removes the infusion tube once it has penetrated the bone a predetermined depth. As the introducer is withdrawn, the infusion tube remains in the bone. The ball release mechanism and other aspects of the apparatus can be modified to yield different penetration depths. The present invention also relates to a method and apparatus for locating the site of infusion and for relieving strain and stress on the infusion site. The template patch uses a key anatomical feature of the bone as a reference point to a target zone for infusion that is located a predetermined distance away from the feature. The template patch has a tube clamp and a covering that protect the infusion site from external forces.
