Patent CA-2262935-A1 (CA)
Inventor: WOODSIDE ANDREW B
IPC: C03C25/26
Filed: 1997-08-07
Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers (10), such as reinforcing fibers (12) suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable.  Heat energy may be employed to lower the viscosity and improve the wetting ability of the applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers (32) are used to form a composite strand (14), which may be subsequently processed in-line or off-line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet form and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles. Each strand is made from fibers, including reinforcing fibers and optionally fibers of a matrix material, that are impregnated with a chemical treatment so that the treatment is disposed between substantially all of the fibers.

Title: Simplified ink jet head
Inventor: PALIFKA ROBERT G
IPC: B41J2/16
Filed: 1995-03-17
Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive.  The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate.  An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12).  Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate.  Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages.  In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.

Filed: 1996-09-06
Abstract: A filtration apparatus is provided, of the type that includes a stack of rapidly rotating membrane packs (32) and a stack of stationary separator elements (36A, 36B) interleaved with the membrane packs to leave thin gaps (40A, 40B) between them, which obtains the advantages of both series-connected and parallel-connected systems. A feed conduit (82) connects the radially outer ends (110) of the gaps, to carry feed fluid into and out of each gap.  The rapidly rotating membrane packs cause radially outward flow near their surfaces, which causes radially inward flow (102) near the surfaces of the stationary elements, to cause fluid flow radially inwardly and then outwardly through each gap. The stationary elements have apertures (131-138) to equalize the pressure on opposite sides thereof and to promote fluid shear at the membrane surfaces. An accumulator (140) is coupled to the feed inlet (12) to maintain feed fluid pressure during an abnormal loss of feed fluid pressure, for the time required to stop rotation of the stack of membrane packs.

Title: Method for forming article using sol-gel processing
Inventor: BHANDARKAR SUHAS DATTATREYA
IPC: C03B37/016
Filed: 1999-06-07
Abstract: A silica body useful for forming an optical fiber preform exhibits an ultimate strength of at least 20 MPa at 10 wt.% water loss. The body attains this strength, it is believed, by precipitation of silica at the contact sites of adjacent silica particles, thereby forming neck regions.      The resultant network provides the strength to the gel body, such that the body is capable of being dried under more severe conditions than a gel body formed by previous sol-gel methods and is also more robust toward handling. The controlled precipitation is attained by inducing gelation and initiating drying at a pH of about 10.5 or higher, at which silica remains highly soluble. By gelling and drying at this pH level, the solubilized silica appears to precipitate in a controlled manner at the point of contact of adjacent silica particles, since such sites are the minimum free energy sites for precipitation.

Patent CA-2277449-A1 (CA)
Inventor: MOUNT DENNIS WILLIAM
IPC: B01D1/00
Filed: 1999-07-07
Abstract: A vapour recovery system and method for volatile chemicals which enhances the efficiency and safety of the process of recovering the vapour is disclosed. The volatile substance is vaporized in a distillation unit under the control of a computerised heating system. The resulting vapour is first directly condensed by bubbling the vapour directly into the liquid phase of that volatile substance. Any vapour that remains after having passed through said liquid phase accumulates above the liquid phase and is allowed to escape into a vapour management module. The vapour management module facilitates efficient condensation of the vapour by allowing heat exchange from the vapour to a material contained within said vapour management module. Upon cooling in the vapour management module, the vapour condenses, and can run back into the liquid phase through which it had passed when in the vapour phase. The vapour management module has an exhaust that is substantially free of the vapour.

Inventor: MERZ PETER W
IPC: B60J10/00
Filed: 1999-09-27
Abstract: It is described an adhesive compound that is formed by means of specific adhesive system. Due to the specific adhesive system the disconnecting of the adhesive compound is considerably eased, what, in particular, is of great benefit for the quick removal of plastic windows (1) in case of emergency. The specific properties of the adhesive compound are based on its specific structure in which in the middle of the compound between the substrates (1, 4), in particular one plastic window (1) and one flange (4), a specific parting layer (3) is installed by which the two substrates (l, 4) can be disconnected easily. The parting layer (3) is an elastomere, in particular an elastomere that has an extremely high tenacity and an elongation at rupture of 500 % up to more than 1500 % and that shows a good adherence to the assembly adhesive (2) so that the removal can be performed by stretching the parting layer (3) whereby it constricts and thereby peels off from the adhesive (2).
