Patent CA-2367641-A1 (CA)
Title: Fire block conduit coupler
Inventor: HARLE MANFRED
IPC: B28B23/00
Filed: 2002-01-15
Abstract: A coupler which is used in coupling plastic conduit through a separation in a building has plastic end regions for an overlapped accurately positioned sealed coupling with the plastic conduit to each end of the coupler. The plastic end regions are separated by an intermediate region formed by a wall of plastic based intumescent material which defines a fluid flow passage through the coupler. The fluid flow passage wall has a sufficient thickness of the intumescent material to produce a complete blockage of the passage when the coupler is subjected to conditions which cause an intumescing of the intermediate region wall material.

Title: High performance engine oil
Inventor: MAXWELL WILLIAM L
IPC: C10N40/25
Filed: 2000-02-15
Abstract: High performance engine oils and other liquid lubricants comprise a liquid lubricant basestock of low viscosity from 1.5 to 12 cSt (110C) with two dissolved polymer components of differing molecular weights.  The basestock is preferably a single PAO or blend of PAOs with a co-basestock component which is preferably an ester or an alkylated aromatic of comparable viscosity. The lower molecular weight polymer is highly viscoelastic in character and is preferably an HVI-PAO; this component in the lubricant which provides unexpectedly high film thickness and unexpectedly good wear protection under conditions where the second, higher molecular weight polymer may lose some or all of its thickening power. The use of the highly viscoelastic low molecular weight polymer in combination with the higher molecular weight thickener enables the production of very widely cross-graded engine oils, especially oils with a low temperature grading of 0W or better. Oils with cross gradings of 0W20, 0W30, 0W40 or even more widely cross graded, for example 0W70 or higher may be achieved.

Abstract: Selon l'invention, des bits d'activité de liaison inverse sont indépendamment générés par chaque station de base (102, 104 et 106) pour indiquer si la station de base émettrice (102, 104 et 106) a atteint une limite de capacité de liaison inverse. Dans une première forme de réalisation exemplaire, un terminal distant (122) combine les éléments multivoie des bits d'activité de liaison inverse de chaque station de base émettrice (102, 104 et 106) dans son système actif et, en réponse, transmet un signal de liaison inverse uniquement lorsque tous les bits d'activité de liaison inverse indiquent que les stations de base (102, 104 et 106) du système actif de terminaux distants ont une capacité de liaison inverse. Dans une autre forme de réalisation, le terminal distant pondère les signaux d'activité de liaison inverse en fonction de l'intensité du signal de la station de base (102, 104 ou 106) transmettant le signal d'activité, puis détermine s'il faut transmettre sur la base de la somme pondérée des signaux d'activité.

Title: Dowel for fusing bones
Inventor: FERREE BRET A
IPC: A61F2/30
Filed: 2001-05-24
Abstract: Existing bone dowels are improved through the use of rigid, preferably metallic end plates (306, 320). The plates are positioned relative to the anterior and posterior end surfaces of the bone dowel. The completed structure may be inserted, removed, and positioned into the vertebrae. The use of the rigid endplates (306, 320) facilitates load sharing which helps to prevent graft fracture. In the preferred embodiment, the end plates (306, 320) are positioned against the end surfaces of the bone section (400) through the use of a link member (308), which passes through the interior of the bone section (400) and connects the end plates (306, 320). One of the end plates (320) may include a threaded bore, and one end of the link member may be threaded to receive the threaded bore of that end plate to hold it in place.

Abstract: A solid fuel composition of spent coffee grounds and/or green coffee bean waste, sawdust and a wax binder is useful for manufacturing a fire-log with more flame output. This combination of solid particulate together with wax burns with a natural-sounding sizzling and crackling. The fuel composition also develops cracks as it burns, in much the same way as natural wood logs do. The cracks expose more surface area to combustion air, thereby enhancing flame output.

Patent CA-2389815-A1 (CA)
Title: Coin purse
Inventor: BOYARSKI JOSEPH LEE
IPC: A45C1/02
Filed: 2002-06-18
Abstract: A method of making a folding coin purse involves forming a first pocket and a second pocket in a layer of pliable rectangular material with seams spaced in from the first side peripheral edge and the second side peripheral edge. The first pocket is substantially larger than the second pocket. The first pocket and the second pocket are then turned inside out, thereby forming a body with a first inside out pocket which serves as a coin confining panel, and a peripheral border framing an access opening formed by a second inside out pocket and the seams. The peripheral border is biased into an upstanding position by the turning of the first pocket and the second pocket inside out. The width of the peripheral border is determined by the positioning of the seams. Folding the body in half prevents coins from exiting the first inside out pocket.

Title: Hammer drill
Inventor: HA BOB B
IPC: B23B45/16
Filed: 2002-06-17
Abstract: A hammer drill with rolling contact at the contact surfaces for transmission of axial force between a drive shaft and hammer shaft. In the case of ball bearings, point contact is obtained. In the case of roller bearings, line contact is obtained.  The area of contact is thus close to zero as opposed to a relatively large area in engagement systems using toothed surfaces. Use of point or line contact reduces heat generation and reduces energy loss due to friction.

IPC: C12Q1/02
Filed: 2001-05-08
Abstract: Microfluidic embryo scaled channels (14) for handling and positioning embryos provide the opportunity to evaluate and treat embryos in improved manners.  Fluid flow is used to move and position embryos within microfluidic channels and channel geometrics may be used to place embryos at specific locations.  Surface properties and compliance (deformation) properties of embryos are evaluated as a predictor of viability. The microfluidic channels provide the opportunity for fine controls of pressure to conduct various evalutions at forces slightly below which damage to embryos is known to occur. Measurement of the distance and/or which embryos roll in a same pressure gradient microfluidic channel provides information, with healthy embryos traveling slower or a shorter distance as they demonstrate more stiction to channel walls.
