Patent CA-2230980-A1 (CA)
Title: Film adhesif de blocage d'ebauches de lentilles
Inventor: HYDE PATRICK D
IPC: C09J7/38
Filed: 1996-07-11
Abstract: Cette invention concerne une bande conformable destinée à la liaison d'un bloc lentille à des ébauches de lentilles ophtalmiques. Cette bande se compose d'un support polymère et d'un adhésif auto-collant. Dans un premier mode de réalisation préféré, la surface du support consiste en un mélange d'un polymère d'oléfine et d'un polymère ayant une fonction acide. Ce mélange peut servir de couche de support, c'est-à-dire directement sur la couche adhésive de la bande, ou encore former la couche de surface externe d'un support stratifié. Dans un second mode de réalisation, la surface du support consiste en un copolymère comportant un monomère d'oléfine et un monomère ayant une fonctionnalité acide pendante. Un bloc lentille peut être collé à une ébauche de lentille ophtalmique par application d'une partie de la bande susmentionnée sur une lentille ophtalmique, ceci de manière à ce que l'adhésif auto-collant de la bande entre en contact avec ladite lentille. La bande est ensuite adaptée au contour de la surface composite de la lentille, avant que le bloc lentille soit à son tour fixé à une partie au moins de la couche de support polymère. Cette bande peut être obtenue par extrusion d'un matériau de support polymère tel que celui décrit ci-dessus, puis par extrusion d'un adhésif auto-collant et, enfin, par mise du matériau de support polymère en contact avec l'adhésif auto-collant. Il est également possible, afin de former la bande, de co-extruder le matériau de support polymère et l'adhésif auto-collant. Dans les modes de réalisation préférés entre tous, cette bande peut être enroulée en un rouleau ne comportant pas de matériau de revêtement intermédiaire.

Title: Serial data transmission of variable length mini packets using statistical multiplexing
Inventor: BHARUCHA BEHRAM H
IPC: H04L12/56
Filed: 1998-03-25
Abstract: AAL2 mini packets are integrated directly onto the physical layer to provide serial data transmission using statistical multiplexing.  This can be achieved by generating a plurality of frames of a predetermined size.  A plurality of AAL2 variable length mini packets are then statistically multiplexed onto the plurality of frames.  A pointer field is then inserted into each of the frames.  The pointer field includes a pointer that delineates the starting place of the next full packet in the frame that includes the pointer field, a framing bit that forms a pattern with other framing bits, and a parity bit.  The frames are then transmitted over a serial transmission line.

Title: Solid polymer type fuel cell and method for manufacturing the same
Inventor: UCHIDA MAKOTO
IPC: H01M8/10
Filed: 1998-04-21
Abstract: An electrode of solid polymer electrolyte fuel cells is produced by a step of preparing a mixed liquid containing an organic solvent, a noble metal catalyst-supporting carbon powder and a colloid of a solid polymer electrolyte having a particle size of 1 nm or more and less than 400 nm, said colloid being adsorbed to the carbon powder and a step of forming an electrode by coating said mixed liquid on one side of a gas-diffusible layer.          According to the present invention, the solid polymer electrolyte is surely adsorbed to the surface of the catalyst and thus a wide reaction area can be secured.          Furthermore, thickness of the solid polymer electrolyte layer can be controlled to one in which hydrogen and oxygen can be easily diffused.
Patent CA-2235995-A1 (CA)
Inventor: BAUGH JOHN L
IPC: E21B23/03

Patent CA-2236656-A1 (CA)
Title: Continuous chain caster and method
Inventor: SPEED BODDY BRUCE
IPC: B22D11/06
Filed: 1996-11-13
Abstract: A continuous chain caster has upper and lower mold assemblies (10, 16) comprising endless belts (12, 18) and chains (14, 20) traveling at synchronized speeds. The mold assemblies meet to form a mold channel (22) which is filled with molten metal from a headbox (24) and feed tip (27). As the molten metal passes through the mold channel, the metal solidifies into the shape of the mold channel. Each belt is positioned outside the corresponding chain so that the smooth surface of the belt defines the surface of the mold channel thereby preventing the formation of fins between mold blocks (32) which make up the chain, protecting the chain blocks and neutralizing deformations in the chain blocks. The upper and lower blocks of the chains have protrusions at opposite ends which engage the opposing blocks to form the sides of the mold channel. By sliding the chains relative to each other, the width of the mold channel is adjustable.

Title: Axial-drive felling head
Inventor: NAUD JEAN-YVES
IPC: A01G23/081
Filed: 1998-07-09
Abstract: Described herein is an axial-drive felling head for restraining, cutting and manipulating trees. The felling head comprises a holder connected to a manipulator arm, or crane, of a logging vehicle. At least partially housed in either a frame or the holder is a motor for rotating the frame coaxially about the axis of rotation of a drive shaft of the motor. The frame is preferably disposed with arms for gripping and a saw for cutting. Advantageously, the felling head further comprises a transmission, preferably a gearbox, for augmenting the torque produced by the motor. The gearbox, which is preferably of planetary type, is at least partially housed in either the frame or the holder. Since the drive shaft is coaxial with the axis of rotation of the frame, the size and complexity of the transmission is thus minimized.

Title: Carbon-carbon piston architectures
Inventor: NORTHAM GEORGE BURTON
IPC: C04B35/83
Filed: 1997-03-06
Abstract: An improved structure for carbon-carbon composite piston architectures is disclosed. Initially, the carbon fabric or tape layers are prepregged with carbonaceous organic resins and/or pitches and these plies (21) laid up or molded about a mandrel, to form a carbon-fiber reinforced organic-matrix composite billets (20) shaped like a "U" channel having legs (26, 27), a "T"bar, or a combination of the two. The molded carbon-fiber reinforced organicmatrix composite part is then pyrolized in an inert atmosphere, to convert the organic matrix materials to carbon. At this point, cylindrical piston blanks (22) are cored from the "U"-channel, "T"-bar, or combination part. These blanks are then densified by reimpregnation with resins or pitches which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes. Once the desired density has been achieved, the piston billets are machined to final piston dimensions; coated with oxidation sealants; and/or coated with a catalyst.
